Cheng Feng sent the information of the four classmates to Ling Xuezhi's computer from the Internet. In the evening, Li Tao sat in front of the computer and watched carefully, and then began to search for records of the case and similar information.

Deng Yuhao hid outside the door and quietly called Sima, he knew that this time Li Tao wanted to find out the truth by his own ability, but this matter was too weird after all, and he was still afraid that something would go wrong. But Sima's phone couldn't get through, so Deng Yuhao had to go back to the house to see what Li Tao had found.

"Look, there's a blog here." Li Tao suddenly said excitedly.

Deng Yuhao and Ling Xuezhi both gathered around to see the above content. This blog is two years old, with only one article called "Cold Walls", which does not even have the author's signature.

"It's the weirdest thing I've ever seen, and I don't know if anyone else has made the same discovery as me. The temperature of that wall is constant at all times, I have measured it, it is about 10 degrees Celsius, no matter how the sun shines, even if you burn it with a lighter for a long time, it is the same. There must be something in this that I don't know, this year is the third year, I don't know, 'he' will come, if he comes, who will be next? I'm so afraid, I'm afraid that one day it will fall on my head, who can help me? ”

"It's probably the wall of Building 9 that someone noticed before we did." Deng Yuhao said.

"You see, this is a recent post, if this person is from the school, then he must know what is going to happen, and it must have something to do with what happened to Cheng Feng." Li Tao said.

Ling Xuezhi said: "It won't be such a coincidence, I think it's weird." ”

When the two heard Ling Xuezhi's seemingly insightful words, they asked him what he had speculated.

"Don't you think this was all planned by that Cheng Feng? It's weird that this blog is like it's made for us, but what is his purpose in doing this? ”

"But it wouldn't have been ready two years ago, would it?" Li Tao said.

"I have a solution." Deng Yuhao said, "Why don't we reply and see how this blogger reacts, didn't he finally say that he wanted someone to help him?" ”

"Well, yes, although it's been a long time, it's not impossible, since he didn't delete it, it means that the matter hasn't been resolved." Li Tao said.

So Li Tao replied: You are NSZG (Nansong Vocational High School), right, we know a little about the wall, can you exchange it with you, QQxxxxxxxxxx.

"Now we have to wait for this person to reply." Deng Yuhao said that he actually didn't want Li Tao to do anything more.

Who knew that Li Tao immediately said: "How can you wait? ”

"What else can I do?" Deng Yuhao said.

"If the four students go missing, the school will definitely still pay attention to it, there should be a record from two years ago, maybe there is something about that wall, we should look for it." Li Tao said.

"I'm afraid the school won't show it to the students." Ling Xuezhi said.

"The archives are on the seventh floor of the school library, so you can't usually get in, but we can find a way." After Li Tao finished speaking, he began to think.

Deng Yuhao patted his chest and said: "This kind of trivial matter, hold me, I have already thought of a way." ”

Li Tao and Ling Xuezhi looked at him in surprise and said, "No, let's hear it." ”

"Hehe, it's not interesting to say it, anyway, this method can only go to me alone, you just wait for me in the bedroom." After speaking, Deng Yuhao walked out, and when he arrived at the door, he smiled at the mysterious smile of the two.

"Why is this guy so active all of a sudden?" Ling Xuezhi wondered.

said that Deng Yuhao let out a long breath after going out. When he heard that Li Tao wanted to sneak into the data room just now, he was so frightened that he hurriedly made up a reason to stop him. The school rules of Nansong Vocational High School are very strict, and the things that are expressly forbidden are never soft, and if they are caught, they must not be ordered to withdraw from school. After thinking about it, Deng Yuhao was proud again, haha, thanks to my urgency, I went to the library to shake it first, and then I could go back with a random reason, and then I could tell Li Tao how tightly guarded it was, and there were many cameras just like the books inside, and there were thirty administrators squatting at the same time, so I couldn't scare you a little detective.

Humming a little tune, Deng Yuhao headed towards the library.

"Here we are." Li Tao said that at this time, a friend was applying, and Li Tao named him "Cold Wall".

"So fast." Ling Xuezhi said.

But this person's avatar didn't flash for a long time, and both of them guessed whether it would be a mistake, but Li Tao still waited patiently and didn't talk to him first, Li Tao asked him to think that he had a decisive clue.

Sure enough, after a while, the man began to speak.

"You're an NS student?"

"yes, you're the cold wall?" Li Tao replied.

"Well, it seems that I'm not the only one who has discovered the secret of Building Nine."

"What else do you know beyond the surface?"

"Missing." Li Tao replied.

"That's all?"

The other party's words made Li Tao very surprised, could it be that there was anything else besides the disappearance? So he returned: "We know less than you do, but we have a solution." ”

"Solve it, hehe, you can't think of what the wall of Building Nine is, and help me solve it, forget it, you better study hard."

Li Tao heard the clue and immediately returned: "You are not a student. ”

"Hehe, the reaction is fast enough, but I advise you, it's better to leave the matter of Building 9 alone, so as not to get into trouble."

Then the man's portrait was darkened. Li Tao slapped the table and said, "Hey, it was too obvious just now. ”

Ling Xuezhi said: "If there is any way, we don't know anything." ”

"I can only wait for Deng Yuhao's news." After speaking, Li Tao lay back.

The library is really popular, it's almost nine o'clock, and it's still full of people. It's just that the situation is different on the sixth floor, except for Deng Yuhao, who is standing at the door of the school's archives, it is empty.

"I'm just saying, how can you just go to the archives." Deng Yuhao looked at the closed door and said. I wanted to try my luck, but this is good, I don't even have to panic, I shook my head, called Sima, but I still couldn't get through, so I turned around and left helplessly.

People have psychological shadows, and Deng Yuhao doesn't know why he wants to turn back, but after all, strange things still happened. The door of the archive room, which was obviously closed just now, is now generously open, not only open, Deng Yuhao found that this archive room didn't even have a door, so what did he see a minute ago?

The darker and colder the door, the more Deng Yuhao's footsteps were attracted, and he slowly entered it with his fists clenched.

When he was a child, adults told him that there was a light switch on the left side of the door, and this time, common sense really didn't deceive Deng Yuhao. Countless fluorescent lights flickered overhead, causing the surroundings to quickly shift between darkness and light. Deng Yuhao couldn't help but feel that these dozens of fluorescent lamps would not stop, they just wanted to flash until Deng Yuhao was scared, afraid that he would leave.

"Smack!" In the end, the archives were still shrouded in a blank white light, as if they had just finished telling an old story of the triumph of light over darkness. The information in the archives is roughly chronological, with the motto and the great achievements on the other side.

"Two years ago, it should have been 2007......" Deng Yuhao searched.

At this moment, there was a sound of footsteps next to him.
