The situation in classroom 201 is okay, Lin Fengmian went in and walked around, not much different from the high school classroom in his impression, but this place has been abandoned after all, in addition to the limited light source, the overall appearance is also a dilapidated appearance.

After searching all the desks in the classroom, Lin Fengmian didn't find anything valuable, except for some waste paper, not even a ballpoint pen.

However, although no supplies were found...... Lin Fengmian still found some clues in the classroom.

Belch...... I don't know if it can be used as a clue.

The blackboard in this classroom is still well preserved, and there are not too many stains on it, Lin Fengmian noticed that there are rows of blurred numbers in the corner of this blackboard, which should be written in chalk, but the retention time may be a little long, causing it to look a little blurry.

After studying for a few minutes and still yielding no results, Lin Fengmian walked out of the classroom.

He had to go to Li Shishi, and the little girl had said that her eyesight was very good, maybe she could see what was written on the blackboard.

said that Cao Cao Cao would arrive, and as soon as he got out of the classroom, Lin Fengmian bumped into the eldest lady who was about to go inside.

"Huh? Fengmian~"

Li Shishi still looked tender like water, she saw Lin Fengmian coming out of the classroom, and probably guessed something, so she took the initiative to report.

"I searched all the rooms I could get into, but I couldn't find anyone...... Maybe there is another way to get into other rooms......"

There are actually very few rooms that can be entered on the second floor, but for soft girls...... What more could you ask for?

Lin Fengmian nodded when he heard this, indicating that the president had worked hard.

"But I just stood outside the door of the science lab and looked inside, and I noticed something glowing on the instrument shelf...... I care a lot about ......."

Just from the name, you can guess that there must be something in the science lab, not to mention the clues, there must be a lot of tools, if you can find something like a scalpel...... Even if it is sharpening the knife, Huo Huo ...... to Liu Jian It's not that hard anymore.

Ah, of course this is a joke, no matter how obscene Liu Jian is, it has not yet reached the point where he deserves death, but Li Shishi's idea Lin Fengmian still agrees, the door of the science laboratory has to find a way to open, whether it is to search for the luminous object or to reserve materials, it is imperative, but before that......

"Miss."

Lin Fengmian scratched the back of his head and said, "I have also searched this classroom, and there is nothing worth noting, but there seems to be something on the blackboard, I am worried about what the clues are, but the light source inside is not good, you can see ......"

"Ah......h

Li Shishi gasped, she seemed to be very happy, she suddenly grabbed Lin Fengmian's hands, "Do you need my help?" Feng Mian's classmate...... You're so polite, you can't let go of any clues, if there's anything I can help with, you're welcome~"

“……”

Lin Fengmian nodded a little overwhelmed, he didn't really understand much about the friendship between girls......

Tsk, just like Hou Ange and Su Kuobei, they are often confusing......

After a polite moment, Li Shishi followed Lin Fengmian into the classroom, she looked carefully in front of the blackboard with her butt cocked for a few minutes, and as Lin Fengmian expected, she quickly gave the answer.

"This is the number......

Li Shishi reasoned briefly by herself, but it didn't seem to have any effect, "90~110...... I don't know what it means......"

90～110？

How does it sound like a volatile value?

“…… Maybe it's somewhere password. ”

Lin Fengmian also pondered for a few seconds, and soon realized that this was Xu Zhaojie's fatal heart rate in the real world, but this thing was useless in the illusion of death, so he motioned to Li Shishi not to worry about it for the time being, and first went to see what the situation was at the door of the science laboratory.

The door to the science lab is locked, but it is equipped with a special lock cylinder compared to the staff office on the first floor......

Ah, speaking of which, there are some hoes and pickaxes on the first floor, and the padlock in the staff room may be opened by brute force, but the science lab in front of me ...... It won't work.

After observing the lock cylinder, Li Shishi asked worriedly on the side, if there is no way to find the key to matching, it is estimated that the laboratory will not be able to enter, but Lin Fengmian does not think so, he pointed to the door of the laboratory and said to Li Shishi.

"This is a very ordinary single-row tooth mark lock, and the spring mechanism inside does not have an anti-theft buckle, and only a little ordinary tool is needed to pry it open......"

"Huh? Does Fengmian still know these things? ”

Li Shishi was surprised when she heard this, in her opinion, Lin Fengmian was just a freshman who had just entered high school, and she looked small and exquisite, but she didn't expect that there would be research on these aspects.

"Ah......h

Lin Fengmian smiled embarrassedly, he really hadn't actually studied the lock-picking skills, but he had seen Hou An Ge countless times in the previous detection process, and he had seen too much, so he naturally understood a little bit of it, Li Shishi said this, it was really a good idea to lift him.

"That Fengmian classmate...... What kind of tools do you need? ”

"Well...... Lin Fengmian thought for a while, and said to Li Shishi, "Miss...... You wait a little longer on the second floor, and I can think of where I can find what I'm looking for. ”

"Okay."

……

"Hey! Stinky little ghost, is there anyone on the second floor? ”

As soon as Lin Fengmian came down the stairs, he was spotted by Liu Jian, who was sitting on the first floor, he shook his flashlight and asked in a strange way.

"Do you care about that?" Lin Fengmian gave him a blank look.

Liu Jian smiled, "Why do you put on a depressed expression, there are so many rooms on the second floor, there are always people who can't get in, maybe your friend is hiding in one of them, as a friend, shouldn't you be more positive and optimistic?" ”

"Wow...... Uncle Liu also has a gentle time? It's disgusting~"Who doesn't have a girl's heart anymore?"

"Dead imp!"

……

Ignoring Liu Jian, who was guarding the staircase, Lin Fengmian ran directly back to the bathroom on the right side of the first floor......

Sure enough, a place like [bathroom] is a gathering place for babies......

What Lin Fengmian is looking for is commonplace, but it is left in the current environment...... It seems that this is the only place to be found.

The short man fumbled in the toilet, and after ten minutes, he dragged a wire back to the door of the science laboratory.

Unexpectedly...... Li Shishi is no longer here.

May be impatient...... So let's go search for other rooms first......

Lin Fengmian didn't take it to heart, he fiddled with the wire in his hand a little, skimmed it into a U-shape, and then began to concentrate on tinkering with the lock cylinder of the laboratory.

"Ah, the door is open......"

was tinkering, Li Shishi suddenly came out from behind, and suddenly her voice frightened Lin Fengmian's hand slip-

"Click."

The door opened.
