I first met Shen Yu in my second year of college. I was twenty-one years old at the time, and she was only nineteen years old in my class.

In other words, when she was nineteen years old, she already had an extraordinary aura.

Ever since that side, my mind has been filled with her shadow. As a person who reads and reads stupidly, I am well versed in the truth of "knowing oneself and knowing one's opponent, and not being defeated in a hundred battles". So before chasing her, I also tried to understand her background. I began to get close to the teachers and classmates in their department, beat around the bush, and inquired about everything about her.

But the results of the spy made me even more confused, because her previous experience was like a cloud, and no one could tell her origin and background.

"I've never seen her parents, and they're said to be abroad." That's what her classmates said.

"When she first entered school, she came with a backpack alone, and she didn't have her parents to accompany her." Her roommate said so.

"Student files are private, and you can't check them randomly - but let me take a look at them for you, don't spread them!" The teacher of the Student Affairs Office said to me.

She typed the name "Shen Yu" into the computer, and then froze there.

"Her registration information - it's weird!"

I hurriedly stretched out my head, only to see that Shen Yu's name, date of birth, ID number, school registration number, household registration location, home address, middle school information, etc. were registered in the file form. Looking at her registered home address, she is from Songshan City, the provincial capital.

The next one is more strange, there is a column called "name of the head of the household". Students are usually still registered in the same household register as their parents, so most of them are registered in their father's name.

But Shen Yu is different, but her name is registered in that column.

This is not surprising, it is strange that her "family relationship" and "emergency contact" columns are empty, and only there is a Songshan landline number in the "emergency contact".

I didn't have any other abilities, but I had the ability to remember it, and I wrote down the number with just one glance.

"Huh? What's going on? Why is there no parental information? I asked the teacher.

"These are entered based on the information in the household registration book, and there should be a photocopy of her household registration book." The teacher opened a link, and sure enough, her household registration information was called up from the system.

Sure enough, she was the only one in Shen Yu's household registration book, with no parents, let alone siblings.

"Strange, strange." The student teacher shook his head vigorously and said.

......

I quit the student office and tried to call that emergency number.

"I'm sorry, the user you are calling is empty, please ......" The sweet female voice rang in my ears.

"Why?" Another, sweeter female voice rang out behind me.

"Huh?!" I turned away in surprise.

Shen Yu was standing behind me at some point, she was carrying a backpack and squinting at me. I turned so hard that I almost rubbed her breast.

"You...... Tired of being alive? Her eyes widened instantly.

"Yes, I'm sorry......"

Because I was in such a hurry, I forgot to hang up the phone, and the prompt inside was still ringing.

“Sorry， the subcriber you dialed……”

I was just about to hang up, but who knew that she snatched it away. She glanced at the number on the screen of her mobile phone, and suddenly Long Yan was furious.

"I heard that you were inquiring about my privacy and kept staring at you! Look at you coming out of the student and sneaking up on the phone to know you're not doing a good job! "She held up my phone and looked like she was about to fall to the ground.

"Don't, I was wrong......" I quickly begged for mercy.

"Don't spy on other people's privacy in the future, otherwise you will look good!" She tossed her phone to me and turned and walked away.

My heart was crossed, and I quickly chased after it.

"That, that, you can ......"

"Can't!"

"You, can you be my daughter......"

"Shut up!"

"Can you be my girlfriend?" I finally spit it out in its entirety.

"Get out!" Without looking back, she quickened her pace towards the library.

This was the first time I confessed to a girl. After that, in the more than two years I spent in college, I confessed to her eight times on and off.

"Are you bothered?" She asked me.

"No, it's not annoying."

"I'm annoyed by you!"

"Then I guess our definition of 'annoying' is not quite consistent......"

......

Time flies, more than two years have passed, and she and I have spent time graduating from college.

After graduating, she went abroad to study, and I joined this cultural company and lived a life of mending the pot and carrying the pot.

But in my third year of work, I made up the pot and actually made up for the shit luck.

At that time, the company was going to make a series of books, but one of the authors wrote too unbridledly, and the whole article was full of typos. Even if the "land" is not used correctly, the key is that it is all wrong.

Publishing a book requires a set of editing, proofreading, and processing work. But looking at the manuscripts of these two authors, "editing plus" is basically equivalent to rewriting, so colleagues don't want to take over as editors.

Just like that, the editor-in-chief remembered me again.

"It's definitely a bestseller, you've done a good job, and you'll get a revenue share!" I probably also felt that the task was too heavy, so the editor-in-chief patted his chest vigorously and made a wish to me.

I couldn't guess the editor-in-chief's intentions, so I decided to ask the author to meet and talk. As a result, a fat man of more than 200 pounds came that day, and he was snorting and panting when he walked. He moved sideways into the small conference room and sat down in the chair across from me.

The plastic chair let out a miserable scream, but it managed to hold on, and finally painfully supported the overload.

"Are you ......?" I asked.

"I'm 'Bai Xiaochun'." He said, "Your editor-in-chief is my uncle. ”

"Ah......" I was stunned for thirty seconds, "your two novels are quite good, they are the ...... of this 'land'"

"I deliberately used the wrong one, the avant-garde author, performance art." He said.

"Okay......" I raised my hand in surrender.

He has a "arrogant" ability, and the two of us can't communicate at all. I had to respectfully escort him to the elevator and watch him try to stuff himself inside.

The editor-in-chief happened to be passing by, and he waved at the fat man, then patted me on the shoulder.

"This writer is a good seedling, Xiaoyan, I gave you good resources. Work hard, and you will definitely get a commission if you have income. ”

I had to nod, and it seemed that the book had to be rewritten for him myself.

Fortunately, since I was a child, I have a great memory, and my brain is like a scanner, no matter how long it is, as long as I look at it, I can immediately call up images from my head.

But Rao is like this, I still spent three months plunging into Bai Xiaochun's complicated novel. It took more than ten hours a day to rewrite, and my eyes were almost blind.

My colleagues were snickering at me, and even Lao Zheng came to persuade me.

"Or- forget it? No, I can push this errand away. ”

I shook my head and pushed? To whom is it pushed? Originally, it was all thrown to me what people didn't do, but I was the company's RECYCLE, and what I didn't do anymore could only be permanently deleted.

Can the editor-in-chief let me delete his nephew's work?

People are not as good as heaven, although it took me half a year's effort, Bai Xiaochun's book became an instant hit. not only became popular, but also quickly resold the film and television adaptation rights at a high price.

"I'm a fat man, but I'm a talented fat man, and my belly is full of talent!" He "snapped" on his stomach for the interview, and spoke as confidently as before.

I published two of his best-selling books in a row, and I sold the rights to the adaptation, and the editor-in-chief finally remembered me, and he gave me a big prize money against the crowd — and of course, he took a bigger share himself.

At that time, housing prices were still cheap, and I used this money as a down payment to buy a one-bedroom house in the rural-urban area.

On the night I signed the purchase contract, I trembled with excitement and called Shen Yu, who was studying abroad, to call him across the ocean.

"I've finally bought a house, we have a house!" I said excitedly.

"Shut up!! What are you doing with me when you buy a house?! She snapped back, and I could imagine her nostrils spewing cold air.

"Hey, hey, hey......" I still smirked excitedly.

"Sick!" She scolded me, but didn't hang up.

"I'll wait for you to come back." I say.

"Back to your head!" She finally hung up with a snap.

"Hey, hey......" I'm used to her way of talking, so I'm still holding the microphone and continuing to giggle.

After that, other colleagues were envious of my bonus, and they asked the editor-in-chief to do the work, and finally I was transferred to the lukewarm and unhurried project of "Rare Book Collection", and I lived a mediocre and ordinary life again.

In fact, sometimes, I miss the fat man named Bai Xiaochun.

......

But there is one thing, God has really been kind to me.

That is, Shen Yu has never been in love, let alone married.

It's not that there are no suitors around her for so many years, but she has turned a blind eye to them.

When she went abroad to study after graduating from college, I was worried every day, and although I could come up with various ways to contact her every day, I was always afraid that one day the line between us would break.

She also rarely talks to me about emotional matters, and she always answers my messages and my phone calls, but if she wants to take a step forward, she always avoids it sensibly.

I often can't help but confess to her, but I am always pounced back by her words.

"I'm celibate, you know."

Or is it –

"Give up and find a kind and considerate girl who can live. As for me, I guess it was a crooked neck tree in my previous life, or the kind that hanged the emperor, so I won't get married in this life. Don't waste any more time with me. ”

But I'm indomitable, I've been defeated and fought, I've been rejected if I've been rejected, it's normal to be rejected, it's not normal not to refuse, and that's what happened if I thought about it.

Besides, as long as she doesn't hate me, I'll crouch next to her tree and wait for what's wrong. I'm still an Arsenal fan, and it's a unique temperament for us to go up and wait for reinforcements every year.

"Or- forget it? Where is there no grass at the end of the world? "When I was eating in the cafeteria at noon, Lao Zheng persuaded me again.

In those days, Xin Xiaoruo just came to the company for an internship, and she sat next to her and sneered.

"Cut, this kind of behavior of his, there is a new term called 'kneeling and licking'. And the person who 'kneels and licks' is called 'licking the dog'. ”

"Dogs are dogs, dogs are so cute." I took a sip of Coke and said with a hicuff.

Xin Xiaoruo glanced at me, with an indignant look on her face.

"You're like that- don't insult the dog, okay?!"

"Well, it's hopeless." Lao Zheng sighed and said to me, "However, once in the sea, except for Wushan, I sometimes envy you, you can persevere, and guard such a relationship." Gee. ”

"What envy! It's all stinky straight men. Xin Xiaoruo muttered.

I didn't pay any attention to them, because I wasn't always passive in the relationship, and I often racked my brains to come up with various topics to get her attention.

Not long after, on the day her foreign thesis was approved, I took the initiative to call her again.

"What are you looking for me again?"

"Congratulations on your paper. You also notified me on WeChat this afternoon. ”

"Don't I have half a sentence in WeChat, so you don't have an excuse to celebrate." She said coldly.

I was speechless for a while, and then I suddenly remembered that I encountered a black boat in the Zhulong River when I was a child, and I thought it was a new topic, so I told it to Shen Yu.

She was silent on the other side of the Pacific Ocean, and I thought she was asleep.

"Hey, are you tired of listening?" I asked.

"No, listen carefully." She actually replied to me in a serious tone this time.

Because of the time difference, I was afraid that she would be really sleepy, so I finished the strange thing when I was a child at a fast speed. The voice was still silent.

"Is it still there?" I asked again.

"Yes." She finally whispered, and then she paused again, as if thinking about something, but finally she said something that cheered me up.

"The two of us may be the same kind of people." She said succinctly.

"What?" I was stunned for a moment - am I the same kind of person as her? How can I be the same kind of person as the goddess?

"Have you changed anything since you saw the Black Ship?" She asked again.

"Nothing has changed." I thought for a moment and said, "I remember everything you say except for good memory—is it?" ”

"Get down to business! Don't play poor! Her tone sounded a little harsh, and I quickly shut up.

"So—is your family on good terms? Happiness? She came out of nowhere.

“…… It's good, my parents are honest people, and they are very good to me. ”

"Oh." She paused, thought for a moment, and continued.

"I want to go back home. When the time comes, you can pick me up at the airport. ”

"What?" I couldn't believe my ears.

"Can you believe it? When I was a child, I saw the exact same black ship. She seemed to be struggling to suppress the emotion in her tone, "And then my home fell apart." I wonder why. ”

Confused, I wanted to continue asking, but I heard her yawn softly in the microphone.

"Are you tired? Then hurry up and rest. ”

"Hmm." Shen Yu's tone was a little tired, and she hung up the phone with a click.

Later, every time I think about this experience, I regret it very much.

If she had been bolder at that time and asked more questions, at least she would have figured out the reason for her entanglement.

It would be nice if we had been more able to reason and no longer be so Buddhist, at least we would have studied the Black Ship Incident to the end and thoroughly studied the Black Ship Incident earlier, then we might have been able to discover the crisis hanging over the city earlier.

......

But thankfully, Shen Yu is really back, which is something I've been looking forward to for a long time.

When she returned home, I naturally went to the airport to pick her up. For this, I also hurriedly bought a second-hand Peugeot.

I always thought that she wanted to find out about the black ship, so I returned to China. But when she returned, she seldom mentioned anything about the Black Ship. Even sometimes when I didn't mean to mention it, she was silent for a while, and then she tried to divert the topic.

She had previously said that her family was torn apart after the Black Boat. This sentence reminds me of the fact that in the registration information of the student office, she was alone in the household registration book and did not have the information of her parents.

I guess the Black Ship must have caused some misfortune and hit her too hard—she may not have been prepared, or had not mustered up the courage to face it.

Therefore, my relationship with her has not changed much.

After Shen Yu returned to China, he did not go to big cities such as Beijing, Shanghai and Guangzhou. She returned to Weiyang, the central city of the region, where she took up a teaching position at Weiyang University and single-handedly helped the school open a major in logic.

I often went to the school to find her, and according to the students who took her classes, she was a serious teacher who was not affectionate, and treated her students as coldly and selflessly as I did.

"Brother Zhuan, can you help me ask for a favor? Last time I went out on a date with my girlfriend from another school, I was ordered by Mr. Shen to deduct my attendance points. A boy surnamed Xue stopped me and said.

"I ...... Try. "It's hard for me to refuse, but I'm also apprehensive.

"Please!" He waved at me, and he ran away without a trace.

I sat on the stairs of the school building with my computer in my arms and looked back at the booklet that came from Hell not long ago.

I asked a photocopy company to help me make the contents of the booklet an electronic version, so that it is easier to turn and does not damage the fragile original.

Although the visitors from Hell had mentioned to me about the Black Ship, I knew that Shen Yu was a bit taboo about the topic, so I didn't tell her about meeting the Hell Stranger and getting an archaeological pamphlet.

I flipped through the photocopied booklet text on the computer, which contained a record of the Western Night Kingdom, in addition to the content of the country's subsequent disappearance of 10,000 people, there was also a "Western Night Destruction Puli Three Kingdoms Text", which seemed to be a document sent by the military town below to the Metropolitan Protectorate.

I later checked the information, and the Western Night Kingdom was a small country in the Anxi Prefecture, but it suddenly grew in strength during the Tang Dynasty, and also attacked the nearby three countries of Puli, Deruo, and Yinai.

But unexpectedly, after Xiye conquered the Three Kingdoms, he did not occupy the city or plunder the wealth. They moved all the people of the Three Kingdoms to the national capital of Huggandu City as slaves, and the most interesting thing is that it is recorded in the documents-

“…… West Night ...... plundered the iron cauldron of the Three Kingdoms and returned to the ......"

The iron kettle is the iron pot, which means that the West Night Kingdom snatched all the iron pots of the three countries and brought them back to their own capitals.

Xiye Country is also too ruthless, not only everyone is arrested, but even the cooking pot is not spared......

I was giggling with my notebook in my hand when I heard the sound of a string of crisp high heels.

I quickly closed the computer and looked up obliquely, only to see Shen Yu wearing a knee-length plaid skirt and a white shirt standing in front of me.

She didn't wear stockings on her legs, and her legs were smooth and white, like freshly rinsed silk, and I couldn't help it...... Swallowing and spitting.

"It's crooked again!" She coughed vigorously.

"No, no, no......" I got up, "reading, reading......

"Stutter as soon as you lie!" She passed me and stumbled downstairs.

I rushed to catch up with her, and a few girls around me couldn't help but snicker.

"There's a boy named Xue who took your class......" I said breathlessly as I trotted.

"Are you interceding for him? It's quite a loyal thing. She half-turned her head, swept the corner of her eye and said, "Du Wanqian knows, right?" If she is a bully on campus and does not abide by discipline, I will still deduct her attendance points. ”

"Why bother so much, you will be hated like this."

She stopped suddenly.

"When people live, they either attract love or hate." She was halfway through her speech, and finally softened her tone, "Since you brought this up, let him write a review that will impress me." ”

"Hey, hey, hey, gotta gotcha." I was overjoyed, not because Shen Yu agreed to intercede, but because she actually sold me a favor.

"Are you going for a swim? I also brought swim gear......"

"I'm not going swimming today – people came to me at the police station and they said they needed my help with a case." She said.

"Looking for you?" I was amazed.

"Yes, no? They need logical analysis. ”

This is the first case Shen Yu received. The case was a case of continuous home robbery and homicide.

......

I was not involved in this case, and the details later were also told to me by my high school classmate Lin Ying.

Lin Ying is a newcomer to the police department, and has just been promoted to deputy criminal investigation captain, and the two of us briefly shared a table in high school. I still remember when she was wearing a plaid skirt and a ponytail, and when she came up, she picked up a ruler, took a piece of chalk, and drew a three-eight line in the middle of the table.

I was dumbfounded—big sister, this is a schoolboy trick, how old are you and so naïve.

"I," she said, pointing at me and shaking her finger, "I've never shared a table with a boy!" ”

Unexpectedly, a few days later, she took the initiative to pick up the tablecloth again and wiped off the chalk line.

"Keep it, the sleeves are dusty. Besides, you're shyer than a girl, and you look okay. She took off her guard, threw the rag back, and said cheerfully to me.

With this old classmate relationship, I quickly became acquainted with the people at the police station. Since I heard that Lin Ying was at the police station, I often invited the female captain to dinner in order to listen to some of Shen Yu's movements.

Lin Ying was sitting across from me at this time, she had a beautiful face, wearing jeans, a white shirt, a black and white headband on her short ear-length hair, and a pair of sunglasses hanging from the collar of her shirt on her chest.

"Hey, tell me, how did she solve that serial murder case?" I told Lin Ying.

"You want to know about her, no matter how big or small." Lin Ying stared at me and said with a wrinkled nose in disgust.

"Tell me about it!"

"You, you took the marriage money to invite me to dinner, so you are unwilling, you want to get some information, right?" Lin Ying sneered, "Okay, satisfy you." Tsk, when I talk about that case, I feel that Mr. Shen is simply—like a fairy. ”

"Tell me about it."

"You've heard of that case, right?"

"Of course."

That case was a sensation.

The three serial cases occurred in Building 15 of the Binjiang Community, and they did not take more than half a month. The murderer's modus operandi is very simple and magical.

The cases all occurred at midnight, on the upper floors of the building, and the three white-collar tenants who lived alone were attacked, all of whom were men.

The second victim may not have been killed by a single blow, and before he died, he also called the emergency number 120. According to 120, the phone rang and hung up.

The attack was carried out by striking the head with a blunt object, and three young men were to be quickly subdued and killed, and this man must have been a powerful young man.

The deceased's room was marked by extensive turnover, and the belongings taken were cash. And some very valuable items, such as jewelry, electronic appliances and luxury bags, etc., are abandoned by the murderer.

One of the victims also had two gold bars hidden in his home, which the killer turned over and threw on the ground, but still ignored them.

What's even more strange is that the police have never figured out the entrance and exit of the scene of the midnight murderer.

There were no signs of prying on the doors and windows of the victim's home, and there were no pry marks on the lock slots on the outer locks.

It stands to reason that such a situation should belong to an acquaintance committing a crime. However, after checking the relationship between the three victims, it was found that they had no contact with each other and had no mutual friends or colleagues.

They are all tenants - in fact, this neighborhood was originally an old suburban neighborhood, most of the young people in the community have moved to the city, and the rest are some elderly people who live alone.

However, feng shui takes turns, and in the past two years, Weiyang City has developed a new financial logistics park attached to the Binjiang community. The living facilities of the riverside community are complete, and the rent is cheaper than that of the new community, so most of the residents have become white-collar tenants.

They go out early and return late, have a heavy work load, eat mostly and take out to solve the problem, and basically don't know each other.

In particular, the second deceased had just moved to Weiyang, and he was killed on the third day of living in the Binjiang community. He has no relatives and no reason in Weiyang, and many colleagues in his company don't even know him.

Therefore, the suspicion of acquaintances committing crimes was the first to be raised, and the first to be ruled out.

Lin Ying: Then they thought of the courier or takeaway to commit the crime.

But as the investigation progresses, both possibilities are ruled out.

It is impossible for the courier to deliver the parcel at midnight, and even if it does, the tenant will be suspicious and will not open the door for them.

And the delivery person can't knock on the door out of thin air, if he can knock on the door, it must be the tenant who has ordered the takeaway. However, the police investigated the mobile phones of the three victims and found no records of ordering food on the platform or by phone.

Moreover, Lin Ying and they are also facing another strange problem.

That is - what exactly is the purpose of the murderer?

All three tenants are young people who now pay on the go all day and generally don't have any cash on them.

In fact, the killer did not steal much cash after the killing. Although the amount of cash kept by the homes of the three victims could not be calculated, the police investigated their withdrawal records, and none of the three people withdrew more than 3,000 yuan in the past month.

That is, the murderer broke through the door and killed three people, but robbed no more than three thousand pieces of property.

Is it just for such a little money that he committed crimes with such fanfare?

In fact, after the second murder, Lin Ying boldly put forward a hypothesis - that is, the murderer should be looking for something.

After all, the murderers committed their crimes in the same building.

Building 15 is an old-style tower with 26 floors, each with 12 rooms, or a total of 312 households.

Lin Ying put forward a speculation that the murderer had a very important item, which was of high value and illegal origin, but was accidentally picked up or taken away by a passer-by.

By the time the killer found out, it was too late, and he watched as the man took his belongings and disappeared into the tall fifteenth building. He rushed into the building, only to find that the building was so densely populated and so crowded that he couldn't tell which floor or room the person who picked up his things lived.

What to do?

Fortunately, the murderer was not without clues, he should have seen the back of the person who picked up things, and knew that it was a young man.

He squatted in Building 15 and attacked two young men one after another. In order to divert the suspicion of the police, he created the illusion of a burglary.

The reason why the murderer did not steal jewelry and valuables was because those things were not easy to realize, and secondly, they were not the target of his search.

According to this reasoning, Lin Ying sent people to keep an eye on the building on the 15th, and then contacted the police stations and anti-drug teams in other cities and counties to see if there were any major thefts or drug trafficking cases recently.

Unfortunately, most of the messages she received were negative.

What hit Lin Ying's enthusiasm even more was that under the strict surveillance, a third case occurred in Building 15. A young man was killed at 1 a.m., and the officers on guard did not notice any strangers entering or leaving the building!

Could it be that the murderer is inside the building?!

Lin Ying quickly organized an investigation of the residents of Building 15 one by one, but the results of the investigation were inconclusive.

There were no residents in the building who met the conditions speculated by the police, and no one was found who matched the motive for the crime.

Just when the police were at a loss, the leaders of the city bureau somehow found Lin Ying.

"There is a recent article in the circle of friends, introducing a logic expert in our Wei Yang, why don't you ask her for consultation?"

"Leader, you know better than anyone else, logic and forensic investigation are two different concepts." Lin Ying said unhappily.

"If you listen to both, you will understand."

Lin Ying thinks about it, now that the case has encountered a bottleneck, there is nothing she can do for the time being, find someone to talk to, maybe you can broaden your mind.

She then called Weiyang University, but the director of the Academic Affairs Office who answered the phone was a little hesitant.

"Teacher Shen from the Department of Logic......"

"Listening to your tone, is it a problem at school?" Lin Ying asked.

"No, no, we will do our best to cooperate with the police's request. It's just that this Teacher Shen has a somewhat eccentric temper, and he usually doesn't want to socialize......"

"This is professional consulting, not social." Lin Ying replied.

She was actually prepared as well, because in general, it is normal for an expert professor to have a little temper. But what I didn't expect was that things seemed to be going quite smoothly.

The legendary and obedient teacher Shen actually agreed to the invitation of the police station, and after class that afternoon, she appeared in the police station.

“…… And such a beautiful university teacher......" Yu Yiqing, the newly recruited female police officer, said with wide eyes, "Even a woman like me can't help but fall in love with her......"

"Xiaoyu, don't you like men?" Shi Chong, a male police officer who had come a year earlier, stared at Shen Yu and asked Yu Yiqing.

"Men? Hehe......" Yu Yiqing sneered at him.

Although Shen Yu was born with an indifferent face, Lin Ying still welcomed her in with a smile.

"Teacher Shen, do you drink tea?"

"No need, I took a look at the materials sent at noon, and I already know who the murderer is."

"What's that?" Xiao Yu spoke out the question for Lin Ying.

"I need to confirm the accuracy of some preset premises," Shen Yu ignored Xiao Yu's questioning and said to himself, "First, are you sure that when the third case occurred, no one in Building 15 entered or exited the building through any passages?" ”

"This ...... Pretty sure. Lin Ying said.

"Second, are you sure you can rule out that all the young tenants in the building are not suspects?"

"This ......"

"Please don't hesitate to answer, it's important." Shen Yu said bluntly.

"Hey, you look very pleasing to the eye, why are you talking so unpleasantly—this is our captain!" Xiao Yu shouted at Shen Yu.

Lin Ying gestured to Yu Yiqing, and then said succinctly: "Sure." We carefully searched the rooms of various young tenants and found no evidence related to the scene. ”

"What is evidence of a connection at the scene? Fingerprints or DNA information? ”

"In fact, such a direct clue was not extracted from the scene. We analyzed the height and appearance of the suspect by technical means through the height, angle, and scar of the wound. This analysis is accurate. ”

"But it's not the same as the tenants, does that mean?"

"That's right. So, basically no clue yet. ”

"Understood, thank you Captain. Let me briefly state my own analysis, which is actually a simple syllogism.

"However, speaking of the syllogism, let's talk about my first instinct when I read the dossier - that is, what kind of identity did the murderer have to allow him to enter the homes of the three victims without a trace, and then easily hammer the three to death?"

"This is also the biggest doubt—does Mr. Shen have an answer?" Lin Ying asked rhetorically with a smile.

"Of course there is, and the reason is the absolute confidence of the victim in relative strength."

"What...... Thing? Xiao Yu was stunned.

"Okay, then let's not talk about this......" Shen Yu continued, but her words were interrupted by Shi Chong again.

"This beautiful sister seems to be very jumpy when she talks."

“…… Let's move on to the syllogism. Shen Yu ignored the Shi Chong and Xiao Yu, "Everyone is engaged in criminal investigation, and they must be familiar with the application of the three-stage interpretation." So I don't want to make an axe, so I just say the conclusion.

"Let's start by looking at Building 15 as a closed area in which there are two types of residents, the elderly who stay and the tenants.

"Now the police have established two premises: the murderer is in Building 15, and the murderer is not a tenant.

"So, some of the occupants of Building 15 have two identities, one as the victim and the other as the murderer.

"This leads to a simple syllogism: there are two types of residents in Building 15: the elderly and the tenants, and the murderer is the occupant of Building 15 – the murderer is not the tenant – so the murderer is the elderly."

Lin Ying and her colleagues were stunned.

"So, that's why those young guests are opening the door. If there is an elderly person outside the door who is trembling and sick and begging for help from a neighbor, not only will they not lose their sense of security – because they are much more powerful than an older person in comparison – and they will even feel compassion and responsibility.

They hurriedly opened the door and welcomed the old man in. Some people may help the old man into the house, and some people rush to call the emergency number, but they don't notice the murder weapon hidden in the old man's sleeve......

"But I think the first case should be the induced psychopathic violence. However, after the murderer was thrilled to commit the crime, he unexpectedly gained psychological satisfaction and dependence, so he kept looking for a desirable target and began the massacre in the same building......"

Soon after Shen Yu finished his analysis, a series of murders in the Binjiang community were solved.

The suspect turned out to be an old man, and he was also a woman.

When she was young, she was in good health, full of confidence, and she had a stubborn temper and a particularly strong sense of jealousy.

Later, after retiring, she paid special attention to physical fitness, so although her hair was gray, her physical strength was actually very good.

And the reason why she killed people is jaw-dropping, it turned out to be to get rid of the loneliness of the elderly.

The suspect had a son, who bore her a grandson. The son works as an auditor in an accounting firm, is a trapeze, and does not visit his mother several times a year.

The suspect loves his grandson very much, and his grandson is also in college and is busy studying and falling in love. Sometimes the suspect misses his grandson and calls him, but either no one answers, or he is hung up instantly.

In the middle of the night on the day of the first incident, the suspect suddenly felt uncomfortable, and she called her son's phone, but it kept a busy tone. She wanted to call 120, but she was afraid that she would not have anyone to take care of her before the ambulance came.

She remembered that there was a young man who rented a house in the corner of the hallway. She clutched her chest and walked over and rang his doorbell.

The young man looked through the cat's eyes and saw that it was the old neighbor standing in front of the door with his chest clutched, and he hurriedly opened the door and asked her what was wrong.

The suspect said that he was uncomfortable, and the young man quickly invited her into the house, poured her a cup of hot water, and then turned on her mobile phone to make an emergency call.

Just then, the suspect stumbled upon a photograph in the room.

In the photo, the young man is holding an old man with gray hair, and the two of them are smiling very happily.

The suspect asked, who is this?

The young man replied, "This is my grandmother, who loved me the most when I was a child, and sometimes I have been away from home for a long time, and I really want my grandmother to cook." In order to catch up with next year's job stability, I have to take her old man Wei Yang to live for a while.

The fire of jealousy in the suspect's heart burned brightly - why does that grandma have such a good grandson!

The more she thought about it, the more angry she became, when she caught a glimpse of a wrought iron vase next to her. A demonic force took control of her hands, and she suddenly felt no pain in her chest, she stood up and touched it, reaching out to pick up the vase......

Unexpectedly, her movements were seen by the young man who was waiting for the phone to turn on.

Grandma, what are you? The young man asked.

Oh, I think this vase looks good.

The young man didn't say much. At this time, the phone was already turned on, and he lowered his head and began to make calls.

With a "bang", the heavy vase base chiseled through the back of his head.

After the murder, the suspect somehow calmed down more. She felt her heart beat more steadily and her breathing easier.

She also sat on the sofa for a while, then went into the back room and turned all the young man's belongings out, creating the illusion of a burglary.

She didn't want anything that could identify her, no matter how valuable. In the end, she only took more than 500 yuan in cash from the drawer.

The renminbi in circulation could not be traced, and she got up as she thought, trying to erase all traces of her visit.

As for this vase, let's take it away and throw it away. The young man is just a tenant, and there is one less vase in the house, so he probably can't find out.

To the suspect's surprise, the young man's death was discovered by the unit the next day. After the news of the murder in the community spread to the Internet, she soon received a call from her son.

Mom, are you alright? It scares the hell out of me! Don't go anywhere these days, I'll see you tomorrow! The son said in alarm.

The next day, the son took the whole family to the Binjiang community, asked for warmth for a long time, and installed an alarm at the door of the house.

On the third day, his son went on a business trip, and he entrusted his grandson to visit his grandmother. The grandson brought a girlfriend, and the girl was very well-behaved and helped her grandmother cook at home.

It turns out that the dead in the community can still often find their families, so let them die......

The suspect thought so in her heart, and repeated the same trick, making a second and a third case one after another, but her tool of crime changed from a vase to an old wrench.

After the third case, the son was completely panicked, and he rushed to the community and took the old mother to live in his home. Therefore, when the police investigated Building 15, they did not enter the door to check the suspect's residence.

......

This is the truth of the first case that Shen Yu helped the police solve. Listening to Lin Yingyi today, I feel more and more that the woman I love is extremely cool.

"Amazing, amazing. I really didn't look away. While eating, I admired Lin Ying.

"What's the matter with you? You're going to die. Lin Ying began to persuade me, "It's really rare to see a Buddhist chasing girls like you." I really don't know if she's abnormal or if you're abnormal. ”

"Why not chase? Did she say that she would never marry? She only said that she was a celibate. ”

"Don't these two mean the same thing?"

"At least not in terms of formal logic—I've been studying logic lately, in order to have a common language with her, hehe."

"Okay, if you work so hard, maybe there's a slight possibility." She seemed to be comforting me, but I felt that any encouragement and comfort I had heard in this matter was true.

"Then there's hope for me—do you think I'm like a spare tire?"

"Don't insult whether the spare tire is good or not, you're a snow chain at best. Also, you invited me to dinner and chose to be next to the university, did you wait for the end of the meal, and the bell rang over there, so you wiped your mouth and rushed over to offer your courtesy? ”

"Who's going to be courteous?" I asked rhetorically, feigning confusion.

Lin Ying glared at me, just as her WeChat rang, she glanced down at her phone, picked up a napkin to wipe her mouth, and then hurriedly stood up.

"I'm not poor with you, there's another big case, I have to go to the scene quickly."

"Hey, I spent two hundred yuan to invite you to dinner, and we only talked for less than five minutes."

"Look at your unproductive energy! Oh, by the way, I'll give you a move, there is a recent film called "Lu Yao Zhi Ma Li", which is about the spare tire and the goddess. You can ask her to check it out, in case her hard-hearted heart is impressed. Lin Ying left this sentence and left in a hurry.

I watched Lin Ying walk away, looked at the food on the table, ate it slowly, and then bought two tickets at a nearby cinema. Seeing that it was almost time for Shen Yu to get out of class, he hurried towards the teaching building of Weiyang University.

Today was a day of great luck, as soon as I entered the door, I saw her coming down the stairs.

"What are you doing again?" The usual opening remarks are so used that they are almost enemas.

"Why do you say that?" I rushed over to help her carry her bag, but she carried it over her shoulder.

"Yesterday came, the day before yesterday came, the day before yesterday, the day before yesterday, the day before yesterday, the day before yesterday, the day before yesterday...... Forget it, you're almost out of necessity when you come to the school to find me. ”

"Not really. I have just read the concept in the book, and the law is inevitable, objective, universal and eternal. It's actually a coincidence that I came to the school to look for you, for example, I happened to be passing by here today, and then I had a whim and wanted to invite you to a movie. ”

"Are you still endorsing? - What movie? Shen Yu walked forward quickly, and I followed closely behind.

"Lu Yao Zhi Ma Li".

"Don't look."

"It's pretty good."

"Isn't that what we mean about the spare tire? Do you think you're like a spare tire? She suddenly stopped, turned around and asked me a question, and asked me so much that the second monk was confused.

"Not really. Lin Ying said I was not qualified. ”

She snorted and laughed.

"Let me be clear, I've never used you as a spare tire."

"Then can I turn positive?"

"Die." Shen Yu glared at me, "Did you drive?" ”

"It's on."

"Then pull me to the scene of the killing. Lin Ying said that it was a big case and needed me to go over, and there were already more than a dozen missed calls on her phone. ”

"That'......" I hesitated a little as I held the two movie tickets in my hand.

"Let's go! I won't go this time, I'll ask you to see it next time! ”

"Really?! I parked my car on the side of the road outside the school. Can I go in and have a look at it this time? ”

"You're not afraid of being scared?" She didn't look back at me, she looked ahead and giggled.

"You're not afraid, how can I, a big man, be afraid?"

I was ready to perform well in front of Shen Yu, so that she could impress me.
