Like many middle schools in Guangzhou, Chenhui Middle School did not have too strict verification measures when some of its students returned to school after lunch break and lunch break at home.

Mr. Demon squinted, stretched, stretched his slender fingertips into his pocket, and took out a selfie of Liu Yanshi - Mr. Demon downloaded a human-looking dog from Liu Yanshi's Weibo, made it similar to the size of a celebrity signature card, and spent five yuan in the print shop to make a beautiful card.

With Liu Yanshi's image of a bit of star temperament, it really looks like a signed card of an international supermodel.

He walked towards the security booth not far from the school gate.

"Uncle Security! Uncle, are you free, I would like to ask you for a favor. ”

Uncle Huang, the security guard, listened to the call outside the window, and turned his head to see that it was a student wearing a school uniform from Chenhui Middle School.

"What's the matter?"

"Ah...... That is true. The student scratched his hair:

"I have a relative who sent this and asked me to pass it on to this senior sister. But we don't know which class the senior sister is in, and we don't even know if the senior sister has transferred to another school now, only the name of the senior sister; So ......"

"Ah, that's fine." Uncle Huang generously agreed, took the signed card from Shi Zuocai's hand, and took out a bill from the drawer, "Write down your name, and I'll give it to her later." ”

Shi Zuocai agreed repeatedly, and wrote "Lin Yushang" on the paper; After a moment's hesitation, he said:

"My relative said that this gift is a signed card of a famous Australian model that she and Lin Yushang chased together, and the price will be more expensive; So, I hope to make sure that it is in her hands as much as possible......"

……

Sitting in the stands by the playground with his legs crossed, he quietly looked at a stone on the playground, like an autistic child who had been lost in a mental hospital.

Mr. Demon effortlessly bought a school uniform from the school uniform store next to him and sneaked into Chenhui Middle School, but he was a little too excited.

It never occurred to him that he might not be able to go out before school.

In fact, before he could take a step towards the school gate, he was stopped by the security guards.

The way he dealt with this mistake was also fairly simple. Leave the control of your body to the stuffy oil bottle, while you hide in the depths of your mind and go to sleep.

On the football field in front of the stuffy bottle, many students are excitedly playing football. And he just wanted to crash headfirst on the steps of the stands.

Maybe I need to think of that annoying spirit as a bigger trouble than Liu Yanshi. He thought.

Of course, the afternoon of reflection that Mr. Demon had "won" for him was not a bad thing for him. In the empty stands, he can better organize the memories in his head and complete the remaining reasoning that needs to be done.

The first thing that appeared in his mind was the case after Lin Yushang disappeared and Liu Yanshi was controlled.

Yes, after the disappearance of Liu Yanshi, another model disappeared from the town.

The model's disappearance is much more "normal" than Hayashi's.

She stayed in the hotel with the other members who participated in the fashion show. Prepare to take a simple group photo after the finishing touches are completed and then disperse.

After Yoo's arrest, the police gave the go-ahead to the show's official push for the finishing touches. Early in the morning after work, the head of the fashion show reminded the models to get ready and found that the room of a model named Xu Siwu was empty.

The police retrieved the surveillance and found that the time of the model's disappearance perfectly coincided with the time of Lin Yushang's disappearance.

In fact, after the show was over and she left the show, she never returned to the hotel.

The disappearance itself is tantamount to a wordless confession: the police are convinced that she should have absconded in fear of crime as soon as she subdued (or murdered) Lin Yushang, and bought herself time to escape through the perfect means of committing the crime.

Naturally, Liu Yanshi, who was not found to be suspected of committing any crimes, was also acquitted.

It stands to reason that as the biggest suspect in this case, it is the model's information that should be investigated by Shi Zuo the most. But the bad thing is that the model's profile, like the vast majority of Yoo's profile, looks impeccable.

The model, Xu Siwu, was about 20 years old when she disappeared and signed a contract with Nicole Fashion Show at the age of 15 to perform for her at the time of the show.

On the official website of the fashion show, all her information can be clearly consulted, but it is all information related to the identity of the model, and there is nothing suspicious to talk about.

But the reason why Shi Zuo decided not to use her as the target of the investigation was not because her file could not be handled.

As soon as he read the details of the case, Shi Zuocai made a judgment diametrically opposed to that of the Australian police: this model named Xu Siwu could never be the murderer of Lin Yushang.

After Lin Yushang's disappearance, everyone focused on the social network in her daily life, from the landlord Anna, the neighbor Susan to the suspect Liu Yanshi, all of whom were investigated and interrogated in great detail.

But in the report, Xu Siwu, who is an ordinary model and has nothing to do with Lin Yushang in the official record, has never been the target of suspicion.

In other words, it wasn't until she disappeared from sight that her disappearance was taken as evidence of self-confession.

If Xu Siwu was the real mastermind behind Lin Yushang's disappearance, then with her meticulous scheming to make Lin Yushang disappear in broad daylight and get away with it, she would never have imagined that her absconding would become the biggest evidence to identify herself.

But she did disappear forever. Moreover, the stuffy oil bottle has been closely verified on the Internet, and since she disappeared, there has never been a report of her arrest.

Stuffy Oil Bottle looked at the flickering computer screen before leaving the door, and couldn't help but purse his lips - even he didn't know what he was thinking at the moment.

He hoped that his reasoning was close to the truth: Liu Yanshi murdered Lin Yushang, and just to clear his suspicion, he took the life of the model Xu Siwu, whom he had never met.

But deep down, there seems to be another voice dissuading him from afar: No, don't. Don't be like that.

Sitting on the playground, looking at the stones under his feet, his thoughts tumbling in his mind, gradually weaving into a network.

If his judgment was not wrong and Lin Yushang's disappearance was planned by Liu Yanshi, then as long as he could catch up with the slightest trace of Lin Yushang's interpersonal relationship, he would always be able to find the relationship between her and Liu Yanshi.

No matter what the truth is, as long as the connection between the two is found, it is equivalent to finding the first breakthrough in the case.

As if deciding something, the bottle touched his neck, stood up, kicked the stone off the ground, and let out a sigh—just then he heard a distant shout.

Before he could replace Mr. Demon, the security guard Uncle Huang had already run in front of him.

"Oh, classmate, why did you skip class and come here...... It's so hard to find you, I'll give you back. ”

Uncle Huang wiped the sweat from his head and took out a photo from the wallet on his waist - it was naturally Miss Liu Yanshi's selfie "signature card".

Shi Zuocai stood in place in a daze, casting a puzzled expression at Uncle Huang; Uncle Huang sighed, stuffed the signature card into Shi Zuocai's hand, and opened the chatterbox:

"Hey...... Classmate, there is no such person among the students of our school in these years......"
