On September 30, 2018, the day after the signing, all of our team members arrived at the police station early. We moved all the computers out of the house and waited for Sangju Technology to ship the new computers.

I told you that we both set a time of 10 a.m., but they didn't come. It is worth mentioning that our captain has not been at the police station these days, and we have no way of knowing where he is. Maybe he went to investigate the real culprit of the case himself, maybe he just looked at us and hid in disgust, of course I hope it's the former.

Finally, Zhang Doudou led a large army to arrive. I saw that Xiao Yu's eyes were already straight, and I told him not to hit her, because I already had the intention of chasing her in my heart. The work he brought was done quickly, and I poured her a glass of water next to me, thankfully she remembered me. But chatting was my weakness, and my initial problems were ridiculous.

"Why didn't you come at the allotted time, and why?"

"You're very bad at talking." Xiao Yu next to him said interruptedly.

I thought she might not answer this question, but she said it in a serious way.

"It wasn't me who came this morning, it was our product manager, but I couldn't get through to her phone, so I had to ship this batch of things instead of her."

I just answered without asking any more questions, and that's when our captain returned. I seriously suspect that he is indeed hiding from the noise, and I can understand him. I introduced Zhang Doudou to the captain, and the captain asked politely.

"I've used your company's products very well, thank you."

"Thank you, I feel honored." After a brief pleasantry, Chen Doudou and the others left, how I wish she could stay here a little longer, even if it was for a minute. But I don't know when the next time I'll meet her will be. I didn't expect the next time I met him so quickly.

At one o'clock in the afternoon, we received a call from the police, it was none other than Zhang Doudou, I heard the voice over there was her, and I snatched the phone from Liu Xiaoyu's ear. I was afraid that she was in danger on the other end of the phone, but fortunately he was just the one who reported the crime. The real victim is Ma Shuang, the product manager who is going to ship the goods today, and the specific situation is not yet known. In this way, the captain, me, Xiao Yu and Cao Yang quickly rushed to the scene of the crime, and I deeply felt that this time it was the murderous maniac again, and I swore to find him out this time.

The deceased's name was Ma Shuang, 28 years old, and he was the company's product manager, and it was discovered that his identity was Zhang Doudou. The deceased was lying on his stomach on a computer desk with a 30-centimeter-long dagger stuck behind his back, and there was no trace of a fight at the scene. According to Zhang Doudou's recollection, he had lunch and wanted to see if Ma Shuang had come, Ma Shuang's office was not locked, so Zhang Doudou entered it in a grand manner, but he didn't expect such a bloody scene in front of him. Zhang Doudou, who reported the case, looked like he had never seen such a formation, and he was so frightened that he didn't dare to be born next to him. There was a strong fear in his eyes.

The first thing the captain and I did when we got there was to see if the deceased had the symbol of the mysterious black spider on his body, and as we expected, the tattoo of the black spider appeared on the back of the deceased's neck. I think it was that Nangong Ming who came out to commit the crime again, and the crime again and again slipped away from our eyes again and again.

The medical examiner quickly made a preliminary determination of the deceased, and the time of death of the deceased was between 9 and 11 a.m., which was the time when she could not be found. We didn't see the suspect as Zhang Doudou or the chairman Na Yongbo, we just quickly attributed the mastermind behind this case to Nangong Ming's murderous maniac.

Just as we were looking for sufficient evidence for this conclusion, the exciting news came. Through the discovery of the identification team, a mysterious half of a fingerprint was found on the thirty-centimeter dagger, and it was found through the comparison of the most advanced technology that it was really Nangong Ming, the suspect in the murder case three years ago.

After hearing this news, we were like being beaten with blood, and finally the process of solving this case had the right direction. We immediately put a wanted warrant on Nangong Ming, and united the whole country to see if we could catch Nangong Ming's clues.

We also contacted our police friends in Canada in the hope that they would also help us morally and bring this cruel murderer to justice sooner.

We held a conference for this in which only our criminal police participated, and we seemed very relaxed at the meeting, and finally determined the identity of the murderer after nearly half a month of terrifying experience. We all have people who propose to close the case directly and throw the work of catching Nangong Ming to the above, after all, Nangong Ming often disappears after killing people. However, this proposal was not approved by the captain, who told us that he felt that there must be some secret in the case. He pulled out a few photos of himself and shouted loudly.

"I would like to ask you to take a look at these four photos, why do the deceased have the tattoo of the mysterious black spider on their body after they die? I don't want to jump to conclusions until we get to the bottom of it, all the evidence isn't something you ask about, it's something you need to discover. ”

We were speechless when we asked this question, and we had to pretend that we were continuing to solve the case, but in fact there was still a week left before the case was submitted, and when the time passed, we would not have to worry about this murderer.

Just after the meeting, I saw Cao Yang and the captain whispering at the door, and I saw that Cao Yang had never been so excited, because in the eyes of everyone, he was always polite and polite. And this time he danced and begged for something, and I couldn't ask, so I could only pretend to be drunk and leave without seeing.

I finally stayed up until eight o'clock in the evening in the office and was ready to go home. I was unexpectedly happy and excited to go home this time, the evidence of the murderer was finally found, although we haven't caught him yet, but at least we know what kind of person he is, and I feel extremely proud and proud that I participated in this big serial murder case for the first time.

In this huge city, we are all incomparably small, and this insignificance is incomparably great, and this greatness depends on whether you have completed your mission. And I felt that great sense of insignificance at that time.

But even now, I can't imagine that I only had one night to enjoy this peaceful happiness at that time.

October 1, 2018, a sacred day, we ushered in the National Day. But this National Day started with a phone call I received in the morning. At six o'clock in the morning, I was lazily lying in bed enjoying the pleasure of nothing, and suddenly my phone rang. Maybe it's a habit I've developed recently, and I felt a sense of disobedience at the time. I picked up the phone, and it was Liu Xiaoyu on the other side of the phone. I only heard Liu Xiaoyu shouting loudly.

"Oh no, Wang Wei! Cao Yang is about to be arrested. ”

I didn't believe it at first, and I shouted impatiently. "That's what you called me? Today is not April Fool's Day, how can we be arrested if we are policemen? ”

"You heard him right, now I'm going to escort him to the Public Security Bureau, he broke into the house illegally last night!"

I still didn't believe it, but listening to his tone, he shouldn't be lying to me, so I had to pack up and go to the Public Security Bureau. This is indeed the case, Cao Yang sneaked into Na Yongbo's home in the early hours of last night, and was found and caught by security guards after entering the room and reported the crime.

I couldn't understand why he did this, and he sat alone in the interrogation room waiting for his interrogation to begin. I looked at him from the monitor, and he was not nervous at all, on the contrary, he sat there calmly, and he was still talking to the familiar policeman next to him, talking and laughing, and he was not nervous at all. This kind of scene immediately reminded me of the appearance of him and the captain after the meeting yesterday, I was just about to go to the captain to ask what kind of misunderstanding made Cao Yang sneak into Na Yongbo's house late at night, because I knew Cao Yang and he wouldn't steal anything. There must be something hidden that would make such a risky move.

Just when I found the captain, before I could speak, he pulled him to the interrogation room, and Cao Yang was interrogated by me and the captain. I was here to ask all the questions, and the captain was just silent.

"Why did you sneak into Nayongbo's house in the middle of the night?"

"For the sake of the case."

"What kind of case, why don't you follow the order and make your own decisions."

"Because of yesterday's murder, I know Na Yongbo too well, he was my college roommate, and now he is a young and promising entrepreneur. You don't know how he made his fortune, that is, he deceived the common people in the countryside to borrow his usury, and my fellow villagers borrowed from me, including my parents. However, he changed the contract without authorization, and the interest rate became higher and higher, so that he could not repay the loan, and as a result, he grabbed the land and house, and after changing hands at a high price in the market, he became the current entrepreneur! ”

"Do you know him that well?"

"Of course, he was an all-rounder when he was in college, and economics, medicine, and literature were all difficult for him, and I think his achievements were inseparable from his talent."

"But how did you relate this case to him?"

"Just because I knew him so well, he was weird in college. None of us wanted to be with him because he couldn't control his emotions all the time. Sometimes excited, sometimes low, completely like a pervert! ”

Speaking of which, I also thought that Nangong Ming was also a strange man, but I can't know if they are in contact or not.

"Then what did you find when you hit his house this time?" I asked with interest.

"Guess what I found? When I first entered his house, the moonlight was reflected, and I saw a photo of a celebrity from the Republic of China period hanging on the wall of his house, I don't know who it was, but underneath the photo is a very familiar pattern of "black spider". “

This sentence instantly made my hair stand on end, and the captain next to me suddenly spoke.

"I think we need to find out who the person in that huge portrait is."

At the end of the interrogation, I was still extremely puzzled as I walked out of the interrogation room. What kind of magical clue is this, if there is any connection between Yongbo and Nangong Ming, what is it, and who is that historical figure.

Fortunately, Cao Yang did not steal anything, and his position was also adopted by the Public Security Bureau, and the final punishment given to him was 15 days of administrative detention. Although he escaped punishment, his police position may not be guaranteed. The only thing now is to find the murderer quickly, and maybe he can be reinstated.

The captain suggested that our city library see if there were any books related to the atlas, and we came to the library to frantically look at the books from the Republic of China period to see if we could find some clues. And the librarian is very good, he is a man with a sense of justice. When he knew what we were here for, he led all the bibliophiles to find the only clue. Finally, we found an article in a "Xinhai Essay" written in 1920, the ninth year of the Republic of China, and this article is the article I wrote at the beginning. The protagonist in it is Nahan and his "black spider". Later, in the early days of the founding of the People's Republic of China, the "**" period and the reform and opening up period, we found cases and events that recorded the "black spider".

The answer may be in front of you, that is, Na Yongbo is the descendant of Na Han, and he completed his slaughter with the so-called bloodline of the "Black Spider".

But there are still many doubts, that is, whether the previous three cases of black spiders have anything to do with Na Yongbo, so I told the captain my question.

I remember the captain reading the article for a whole day, looking for the only clue he had. The captain finally slapped the table, and I thought he must have discovered something. The captain took a pen and paper and explained it to me slowly.

"What nationality do you think the so-called Nahan in this article is?"

"Manchu, it says Manchu youth."

"That's right, I guess his Manchu surname should be Yehenara, because it happened after the Xinhai Revolution and it was normal to change his name. But do you know what surname Yehenara changed in the subsequent Chinese surnames? ”

"I don't know, if I do, I'll die."

The answer is that most of them were changed to Na, and the rest were changed to the three surnames of Nan, Bai and Ye. What do you think about that? ”

"Isn't this the name of Nangong Ming, Ye Li, and Bai Hao, could it be that the three of them are the accomplices of Na Yongbo, I know that this case is organized murder!"

The captain laughed when he heard this, and he picked up a spiritual book again.

"It was you who first discovered Nangong Ming's mental abnormality and often behaved strangely, and Cao Yang also confirmed that Yongbo also had mental problems. The similarity between them is that they often change their personalities and styles, so I conclude that it is dissociative identity disorder, which is commonly known as split personality disorder! ”

"Then all four of them have this disease, how can I get more confused the more I listen."

"It's not that they all have split personality, it's that they're just him!"

I interrupted him when I heard him say this, and I couldn't allow him to reason around anymore. I couldn't understand what he was saying. The captain looked me in the eye with a sonorous look, and I was really frightened because I had never seen such a determined look in my eyes. He said it categorically.

"I think the four of them are the same person."

I laughed out loud when I heard this, what kind of bullshit reasoning if it was a person, what would happen to their appearance and identity. I can only answer him with such an imbecile question. The captain continued.

"You look at their profession, first of all, Nangong Ming is a doctor, which allows him to kill people perfectly on the scene without leaving a trace of clues, Ye Li University professor explained that he fully understands the history and culture of his family, and then the key is Bai Hao's makeup artist, I have the right to suspect that he has used his profession to play for a long time, these people are what we often call Yi Rong, and in the end, his entrepreneur status makes him full of funds and will not switch back and forth, resulting in his pennilessness, The most important thing is the ID card or other proof of identity, which his technology company can do. ”

"What can you do?"

"It's 3D printing technology, through which any document can be typed, not to mention that he is a large technology company and has strong financial resources, and it is not difficult to have someone as an eyeliner in major document management places."

I was impressed by his outrageous reasoning, but I did not dare to agree with him. I'm blunt.

"How do you prove that they are a human being? If you have to go to the hospital like that, it's not like you used to ask him to do anything to the suspect, and now you can't do some strange tests on the suspect without a valid reason, and the inspector can't get by. “

"Don't worry, I have a way."

After saying that, the captain said that he had something to do and left, and I returned home in a huff. Thinking about his reasoning all night, I really think that if his reasoning is correct, his abilities are really comparable to famous detectives such as Sherlock Holmes and Meiji Kogoro. Thinking about it, I fell asleep, and I was greeted by the harmonious society I dreamed of.
