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

Menyouping glanced at Zhang Tianyou who was slightly tilted towards him, and kept glanced at him. Suddenly, he turned around and looked at the other person steadily.

"What do you want to ask me."

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

The Adam's apple of the Duoyou Bottle rolled irritably.

“Your voyeurism skills are terrible.”

“…”

"The teacher is almost finished writing on the blackboard. Ask quickly."

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

"Did you and Liu... haven't slept all night?"

Mon Oil Bow was stunned for a while and understood the reason why Zhang Tianyou asked.

He could probably imagine what he looked like at this moment: his dark circles were heavy, his face was nowhere to be looked, his lips were pale, as if his body was hollowed out.

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

No one accidentally saw Liu Yanshi's photo and recognized who she was.

Although this is not surprising, it is also disappointing.

The photo of Liu Yanshi was printed on the card and passed it on to someone. Although it was a devilish man who had a sudden inspiration and used it as a way to buy lottery tickets; but so many teachers did not recognize Liu Yanshi in the photo, which at least shows that the possibility of a connection between Liu Yanshi and Chenhui Middle School was infinitely close to zero.

In other words, all clues have been completely interrupted so far.

He took the card of "big star" Liu Yanshi in disappointment, and Menuo Ping almost didn't know how he got home. In his mind, countless thoughts kept rolling.

According to the inertia of thinking, the first thing that Man Youbou suspected was that someone erased Lin Yushang's information when he was enrolled in school: but this was quickly rejected by himself.

Teachers from different levels of the group said they had no impression of this name, and they were sure that they had never met this student.

In this way, there is only the last one left.

If it was really as recorded in the newspaper, Lin Yushang once said that Liu Yanshi was the one who handled the admission procedures for her, then according to the woman's superb counterfeiting of documents, it is very likely that the school Lin Yushang originally attended had been modified.

But this may undoubtedly be unacceptable to the oil bottle.

According to his estimate, there must be at least two or three hundred high schools in Guangzhou. Finding one person by name is tantamount to finding a needle in a haystack.

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

In this way, the hope of seeking breakthroughs from the people involved in the case is slim. The final hope is to seek breakthroughs from the method of committing the crime, but this is almost an impossible task.

There is not much information about the case in the newspaper, but the brief information outlines almost 100% perfect crime. Mon Oil Bottle also searched the details of the venue online and confirmed a sad fact again throughout the night.

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

...

"Student Zuo Cai, Shi Zuo Cai, Shi Zuo Cai?"

The math teacher wiped the chalk and knocked on the podium. When he found out, Zuo still had no response.

"...Zhang Tianyou, call him."

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

"Is Shi Zuocai thinking about the question just now? Let's talk about the solution to this question."

Shi Zuo said lightly, "I'm distracted." Without looking at the blackboard, he sat down.

The math teacher was already familiar with his wandering around the world, and knocked on the blackboard again:

"Good students, this question is the difficulty of the final question in three-dimensional geometry. We can try the reverse proof method. First of all, let's assume that if the edge ab is not perpendicular to the bottom bcd, what conditions will be obtained..."

Shi Zuocai supported his head on the table, and the math teacher's words seemed to gradually disappear in his ears. Just as the math teacher continued to write on the blackboard, a small plastic bag came from his left front.

Shi Zuocai looked up and found that Fu Yinger, who was half a classroom away from him, looked at him and turned her head.

There was a box of sleeping pills in the plastic bag, and there was a note on it, which was written by Liu Yanshi: "The face is so bad, you should pay attention to rest."

There was also a smile on the note, as if condolences, and as if teasing.

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

Shi Zuo had no desire to explain to him. He lowered his head in a depressed manner and wiped his face hard with his hands.

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

Then he paused and wrote another line.

...

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

He woke up in bed, but he quickly judged the fact from the fatigue level of the body: the damn annoying sperm almost slept all night last night.

Although they often exchange consciousness with each other, the silly oil bottle rarely completely loses consciousness when the body is occupied by others - more often, the body occupied by the other party is somewhat similar to dreaming. Therefore, although the consciousness of the two personalities is not common, they often share memories of everything they have experienced together.

The previous time I completely lost consciousness, but I was hypnotized by Liu Yan's personality. As for this time, it was probably due to extreme mental and physical fatigue and the inability to support the two personalities to move at the same time.

The oil bottle held his head and the headache came like a tide. He sat up and touched his hand towards the bedside table. It was his math book.

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

"Counter-proof law."

There is another line of small words below. It was the last breakthrough he came up with a sudden idea after writing the "Reverse Proof Method".

"what will you do?"

He turned down.

The pages behind the title page of the mathematics book are all catalogs. The large blanks on the catalog page are covered with chaotic writing. In the short browsing, Mon Oil Bottle saw many techniques and tricks that were unimaginable to him.

But these almost perfect designs were crossed out, with the handwriting being hastily and chaotic.

Finally, before turning on the last page of the directory, in the lower right corner of the second to last page of the directory, Mon Oil Bottle saw the words that were not crossed out on the first line.

“It’s so fun, it’s so fun, it’s so fun, it’s so fun…”

The handwriting on the last page was frantically and sloppy, mixed with typos, which was obviously left behind in extreme excitement.

"I have never encountered such an extreme person. I hope I can do it myself in the future. I must tell you! From all the known things, I can't make a living person disappear out of thin air."

"It is impossible to create such a case. I can't do it 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!"
