Lin Xinyi briefly explained the situation to Conan, but Conan still muttered a little in his heart.

No way... He has been "green" too many times these days, and he is worried every day, as if he has become a frightened bird.

It wasn't until Lin Xinyi dragged the detective to the café, dragged him to Xiaolan and Fei Mi, and confronted him face-to-face, that he finally calmed down his worried heart:

"It turns out that Sister Xiaolan is here to meet her mother."

Conan let out a long sigh of relief, and his miserable green little face finally looked a little better.

But Mao Lilan asked with some confusion: "Conan, weren't you at home before?" How did you come to this place? ”

"I..." Conan made an excuse with some embarrassment: "I made an appointment with Gray Yuan-san to come out to play, and I happened to pass by here!" ”

"Gray Plains?" Maoliran looked to the side, the tea-haired girl who appeared with Conan.

This little girl is pink, petite and lovely, although her temperament is a little cold, but like ice cream, it is a little cold.

"Oh... She seems to have been with you yesterday as well. ”

Mao Lilan's gaze swirled back and forth between Conan and Gray Plains, and then he couldn't help but quip:

"It turns out that Conan knows that he has asked girls out to play alone, haha."

As soon as these words came out, Lin Xinyi and Gray Yuan's eyes turned cold at the same time.

"Humph!" Gray Yuan glanced at Conan beside him with disdain, and then quietly pulled away and stood closer to Lin Xinyi.

"Ahem, Miss Maori." Lin Xin straightened his face and criticized with a serious face: "Primary school students know what love and love, if you talk like this, it will have a very bad impact on children's education!" ”

Hearing this sudden preaching, Mao Lilan was a little caught off guard:

Speaking of... It seems a bit strange to make such a joke on a first-grade student.

It's just that herself, as a typical representative of early love, has had a good impression of a certain childhood sweetheart since kindergarten... So, subtly, I didn't notice that there was anything wrong with this.

"I'm sorry," Maoliran apologized with some embarrassment.

She was mainly apologizing to Gray Plains.

Because Mao Lilan could keenly feel that this tea-haired little girl didn't seem to like the joke just now, so she had a kind of hostility towards her.

But Gray Yuan Wai turned his head very unappreciatively, and did not choose to let go of his cold arrogance of rejecting people thousands of miles away.

Then, Miss Gray Yuan raised her head and gently tugged at the corner of Lin Xinyi's clothes.

She used her big eyes, which barely had a trace of fluctuation, but Lin Xinyi could read it, and hinted at it:

"Let's go, let's go home, student bio."

Lin Xin comprehended and returned a silent gaze: "Received."

Then, he took the initiative to say goodbye to Mao Lilan and Fei Miao.

Ms. Fei Mile was very enthusiastic about keeping Lin Shinichi.

She really wanted to take this opportunity to invite Lin Xinyi to have a cup of coffee, not only to express her gratitude, but also to learn more about this profession from her daughter's teacher, and by the way, to talk about her daughter's future life plan.

In order to allow this good student to further gain the support of his family, as a mentor who brings other people's children into the pit, it is not easy for him to refuse parents' inquiries.

So, Lin Xinyi and Concubine Mile chatted for a while before they were finally able to get out.

"I'm home too." Gray Yuan Wai casually made an excuse and followed closely out.

If nothing else, the two of them should go home and learn biology.

But at this moment...

"Ah!!h

There was a shrill scream from the bathroom:

"Blood, good, lots of blood!"

A guest shouted with a pale face as he stood at the door of the bathroom that he had just pulled open, looking so alarmed.

"What?!" Lin Xinyi's pace came to an abrupt halt.

He couldn't help but turn his head, staring at Detective Conan in surprise:

Conan's expression was very innocent, and his life was at stake, and Lin Xinyi didn't have time to complain more about Conan's doom aura.

He didn't delay for a second, quickly took a step, and ran to the door of the bathroom:

Sure enough, I saw that I was in a toilet cubicle in the bathroom...

A large pool of blood that had not yet fully coagulated slowly flowed from under the closed door of the cell.

The bright red color was extremely dazzling, as if the entire bathroom was dyed with a layer of creepy blood.

"Oops." Lin Xinyi's heart sank:

Such a large amount of bleeding, and the blood on the ground is showing partial coagulation...

It shows that the person in the toilet compartment had been seriously injured a few minutes ago, and I am afraid that it was too late to give first aid.

"Don't even go near the scene, I'm a policeman!"

Lin Xinyi first revealed his identity, and then turned to Mao Lilan and said:

"Miss Maori, help cordon off the scene and don't let anyone in the store leave here."

"Hmm." Maolilan nodded solemnly.

She stood up abruptly in her mother's slightly surprised gaze, and a touch of calmness and firmness quietly appeared on her young face.

That vigorous and resolute, professional and capable appearance has a taste inherited from his mother as a "queen" in the workplace.

Fei Mi was secretly pleased with her daughter's performance, so she also stood up from the card seat and took the initiative to say:

"Call the police and block the scene for small things, just let my mother and me help."

"Xiaolan, you go and survey the scene with Mr. Lin."

"That's what you do best, isn't it?"

"Hmm... Just leave it to Mom. Maolilan groaned for a moment, and soon agreed with some gratitude to her mother's help.

She handed over the work of the blockade site to Fei Mi, and quickly took out the latex gloves that she had been carrying with her since joining the work, and followed Lin Xinyi's steps closely into the bathroom full of blood.

"It's... What does it taste like? ”

As soon as he entered the bathroom, the first thing he smelled was not blood.

It was a strange, uncomfortable, pungent smell in the nose.

Although the large exhaust fan in this bathroom has been whirring and the windows are open, the ventilation efficiency is very high.

But the smell still lingered in the bathroom, so much so that even the bloody smell of the blood in the place seemed dwarfed.

"Mr. Lin, how's the situation?"

Mao Lilan didn't pay attention to the smell for the time being, but turned his inquiring gaze to Lin Xinyi.

"People... It should be dead. ”

Lin Xinyi stood in front of the toilet cubicle where blood was flowing out, and said with an ugly face.

Then, he tried to push the door of the cubicle with his gloved hand, but couldn't:

"The door to the compartment was not locked, but the corpse was leaning against the door, blocking the door."

"This..."Mao Lilan was slightly stunned:

"The door is blocked from the inside by a corpse?"

"How is the murderer going to get out of this cell?"

Lin Xinyi was not busy studying this issue, but commanded in a calm tone:

"Leave this alone, and observe the scene in this toilet cubicle."

With that, he walked straight out of the bathroom and asked the café owner, who was still in shock, for a chair to use as a footrest.

Seeing that the café owner happened to have a Polaroid camera, he also asked for it.

In this way, Lin Xin set up a chair in front of the toilet cubicle, stood up, and condescendingly recorded the situation in the cubicle with a photo:

Sure enough, it was the same as what he had just said:

A bloodied female corpse lay close against the door, blocking the door of the cubicle from the inside.

And on her corpse, there was also a bloody knife.

This knife is probably a murder weapon.

What's even more strange is that there are still a few drops of fresh blood on the top of the door panel of the toilet cubicle.

"How can there be blood on top of the compartment door?"

"No matter how much blood is splashed, it can't be splashed on the door frame!"

Lin Xinyi frowned, and a wave of doubt welled up in his heart.

And when he suppressed this doubt, and then carefully observed the face of the deceased in the compartment, which was covered by his long messy hair:

He was shocked to find that the deceased lying in the toilet compartment was the young long-haired woman he had met in the bathroom earlier.

"Damn..."Lin Xinyi's heart swelled with anger:

In the ten minutes that he left the bathroom and chatted with Xiao Ai, Fei Mile and others, a living person he once had a relationship with died so silently.

It is impossible to prevent it, and it is impossible to prevent it at all.

Life with Conan is like a box of chocolates, never knowing who will be the next "candy" to be swallowed by the abyss.

He didn't know how Detective Conan had adapted to this constant stream of sudden changes.

In short, seeing a life tragically passed away by his side, Lin Xinyi's mood was very bad.

"Miss Maori, push the door open..."

As soon as Lin Xin recorded the original situation inside the compartment with a photo, he jumped down from the chair and said to Mao Lilan with a solemn face:

"I'm going to see the body."

"Hmm." Maolilan nodded solemnly, and then cautiously pushed the door of the cubicle in.

The door was pushed open, and the corpse that stood in the way lay in a pool of blood.

Lin Xinyi tried not to destroy the scene again, but carefully avoided the large patch of blood on the floor and got closer to see the corpse.

And Mao Lilan was very quick and helped put away the bloodstained short knife.

"A stab to the heart, which is clearly the cause of death for this massive hemorrhage."

"However, on the neck of the deceased... And strangulation marks? ”

Lin Xinyi observed for a while, and immediately discovered a very strange situation:

A stab in the heart is enough to kill.

However, the skin of the middle of the neck of the deceased can be seen in a horizontal atresia around the neck and a strip-shaped groove around the neck.

The back of the neck is about the third and fourth cervical vertebrae, and there are overlapping knotted buckle marks.

"Two weeks of strip-like cord grooves, overlapping marks on the back of the neck."

"This is obviously a mark caused by someone attacking from behind, using a rope to wrap around her neck twice and squeezing hard."

Lin Xinyi said this, but his expression became a little more relaxed.

Mao Lilan looked at it with some puzzlement:

"Mr. Lin, is there any special significance to this discovery?"

"Absolutely." Lin Xin nodded:

"Strangling people with a rope is one of the easiest means of attack to leave traces."

"First of all, it requires the murderer and the victim to be in close proximity to each other."

"Secondly, it takes a lot of time to strangle people to death and strangle them unconscious."

"The victim is a big living person, and it is impossible not to struggle and resist under the pain of suffocation."

"And in the process of resisting, because the two bodies are close to each other, it is easy for the victim to grab important biological samples such as hair and dander from the murderer."

"At this time, if you look closely at the fingernails of the victims, you may be able to gain something."

As he spoke, Lin Xinyi carefully raised the palm of the deceased and observed it carefully.

And this look... His face changed instantly.

"What's wrong?" Maolilan asked a little nervously.

Lin Xinyi did not answer, but first sniffed the smell of the deceased's hands.

Of course, it is not to take the hand of the deceased to the nose and sniff it heavily, which is extremely unprofessional.

The forensic doctor's method of smelling is actually the same as that taught by a junior high school chemistry teacher, using a gentle fan of the hand to let a very small amount of gas drift into the nasal passages:

"Bleach..."

Lin Xinyi's expression was very solemn:

"This bastard washed the dead man's hands with bleach."
