The last two periods of Tuesday afternoon were math classes, and the students in the audience were doing exercises. The tip of the pen swiped across the paper, and there was a rustling sound in the classroom.

The stuffy oil bottle glanced at Zhang Tianyou, who was beside him, who turned his head slightly to him and kept glancing at him. Suddenly, he turned sharply and looked at the other man steadily.

"What do you want to ask me?"

Zhang Tianyou made an innocent statement: "What did you say? ”

The Adam's apple of the stuffy oil bottle rolled irritably.

"Your voyeuristic skills suck."

“……”

"The teacher is almost done writing the board book. Ask. ”

Zhang Tianyou's eyes wandered left and right for a while, and when he looked at Shi Zuocai, he blushed slightly.

"You and Liu...... Didn't sleep all night? ”

The stuffy oil bottle was stunned for a while, and understood the reason for Zhang Tianyou's question.

He could probably imagine himself at the moment: heavy dark circles, a colorless face, pale lips, as if his body had been hollowed out.

Yesterday afternoon, Uncle Huang, a security guard at Chenhui Middle School, told him that there was no one in the school, and that he had not given up. It wasn't until the other party repeatedly confirmed that the teachers at all levels and the archives said that there was no such person, so they had to give up.

No one inadvertently saw the photo of Liu Yanshi and recognized who she was.

This is unexpected, but equally disappointing.

The photo of Liu Yanshi was printed on the card and passed on, although it was Mr. Devil's inspiration and the practice of buying lottery tickets; But so many teachers didn't recognize Liu Yanshi in the photo, at least it shows that the possibility of a connection between Liu Yanshi and Chenhui Middle School is infinitely close to zero.

In other words, at this point, all the clues are completely broken.

Stupidly took the card of the "big star" Liu Yanshi, and the stuffy oil bottle almost didn't know how he got home. Countless thoughts were tumbling in his mind.

According to the inertia of thinking, the first suspicion of the stuffy oil bottle was naturally that someone had erased Lin Yushang's information when he entered the school: but this was quickly rejected by himself.

Teachers at different levels said they had no impression of the name and were sure that they had never met the student.

In this way, there may be only one last one left.

If it is true that Lin Yushang once said that it was Liu Yanshi who handled the enrollment procedures for her, then according to the woman's amazing forged documents, it is very likely that Lin Yushang's original school has been modified.

But this may undoubtedly be unacceptable to the stuffy oil bottle.

According to his estimates, there must be two to three hundred high schools in Guangzhou, and finding a person by one name among them is tantamount to looking for a needle in a haystack.

This made him have to admire Liu Yanshi's ability to cause trouble.

As a result, there is little hope of finding a breakthrough in the people involved in the case. The last hope is to find a breakthrough in the modus operandi, but this is almost an impossible task.

There is not much information about the case in the newspapers, but the brief information outlines an almost 100% perfect crime. The stuffy oil bottle also deliberately searched the Internet for the details of the venue, and spent the whole night reconfirming a sad fact.

Except for an entrance and exit with eight cameras, not even a pigeon could fly out.

……

"Zuocai, Zuocai, Zuocai?"

The math teacher knocked on the podium with a chalk eraser, but found that Shi Zuocai still did not respond.

“…… Zhang Tianyou, you call him. ”

Zhang Tianyou poked Shi Zuocai with the tip of his pen. Shi Zuocai stood up, his gaze still wandering and distracted. The math teacher frowned and tapped on the blackboard:

"Was Shi Zuocai thinking about the topic just now? Let's talk about the solution to this problem. ”

Shi Zuocai said lightly, "I'm distracted", and he didn't look at the blackboard, so he sat down.

The math teacher was already surprised by his fugue and tapped on the blackboard again:

"Okay students, this problem is the difficulty of the finale problem in solid geometry, we can try the counterproof method. First of all, we might as well assume what conditions we get if the prism AB is not perpendicular to the bottom BCD......"

Shi Zuocai propped his head on the table, and the math teacher's words seemed to gradually escape in his ears. Just as the math teacher continued to write on the board, a small plastic bag passed from his left front.

Shi Zuocai looked up and found that Fu Ying'er, who was half a classroom away from him, glanced at him and turned his head again.

In the plastic bag was a box of sleeping pills, and a note was attached to the bag, which was Liu Yanshi's handwriting: "Your face is so bad, you should pay attention to rest." ”

A smiling face was also drawn on the note. It's like a condolence, and it's like a tease.

Shi Zuocai looked at Zhang Tianyou beside him - he was looking at him incredulously, his eyes were full of jealousy and indignation, and he almost wrote "How handsome you are" on his face.

Shi Zuocai had no desire to explain to him. He bowed his head frantically and wiped his face with his hand.

Suddenly, he stopped and wrote a few words on the title page of the math book.

Then, after a pause, he wrote another line.

……

It was five o'clock in the morning when the stuffy oil bottle regained consciousness.

He woke up in his bed, but he quickly judged from the fatigue of the body that the damn annoyance had barely slept all night last night.

Despite the frequent exchange of consciousness with each other, it is rare for the bottle to lose consciousness completely when the body is occupied by someone else - more often than not, being occupied by the other person resembles dreaming. Thus, although the consciousness of the two personalities is not common, they tend to share memories of everything they have experienced together.

The last time I completely lost consciousness, I was still hypnotized by Liu Yanshi's personality. As for this time, it was probably the result of extreme mental and physical exhaustion, unable to support the simultaneous movement of two personalities.

The stuffy oil bottle held his head, and the feeling of headache came like a tidal wave. He sat up with his support and felt his hand on the bedside table, which was his math book.

He lit the lamp and flipped to the title page of the book, where there were three words he had subconsciously written before giving his body to Mr. Demon to avoid trouble.

"Counter-evidence."

There is another line of small print underneath. That was the final breakthrough he came up with after he wrote the "Counter-Evidence Method".

"What would you do?"

He flipped down.

The last few pages of the title page of the math book are full of table of contents. Large blank spaces on the catalog pages were covered with jumbled handwriting, and in a brief glance, the Stuffy Oil Bottle saw many tricks and tricks that he could not imagine.

But these almost perfect designs are crossed out, and the handwriting is hasty and messy.

Finally, before turning to the last page of the table of contents, in the bottom right corner of the penultimate page of the table of contents, the stuffy oil bottle saw the words that had not been crossed out on the first line.

"It's so fun, it's so fun, it's fun, it's fun, it's fun, it's fun......, it's fun, it's fun, it's

The handwriting on the last page is frenzied and scribbled, interspersed with typos, apparently left in a state of extreme mental excitement.

"I've never seen anything so extreme, and I hope I can do it myself in the future. Gotta tell you! From all that is known, let a living person disappear into thin air, I can't do it. ”

"It's impossible to create a case like this. I can't either! But I can do it...... It's a trick to make everyone think that this incredible disappearance case has really happened in the world! ……”

“…… First of all, I will create a 'Hayashi Yu Shang' that does not exist. ”
