Standing in front of the door of the multimedia classroom, looking at the doors and windows that were sealed by wooden boards, Yu Siqi began to wonder if he had lost his eyes. Because he had seen a figure floating past here and into this classroom. But now it seems that either I am dazzled; Either he saw something unclean.

Neither of these situations is good news for him now, especially the latter, which makes Yu Siqi feel that the atmosphere around him has become a little weird.

The rain was heavier, and the rain-soaked banners on the balconies were blown crooked in the cold wind. It is precisely because of the strong wind that Yu Siqi no longer dares to stand near the balcony.

Judging from the clues we have learned so far, even if I go to other buildings, I may not be able to find a good place to shelter from the wind and rain.

What should I do now!

Yu Siqi, who was racking his brains to think about this problem, suddenly came up with a terrible idea, this idea may not be a good idea in essence, but for him now, it may be the only thing he can do.

Turning back to the door of the Security Section, the black security door basically hindered his fantasy of wanting to enter the Security Section. But he didn't come back to go to the security department, but to the long sign that had fallen in the doorway.

Weighing the material of the sign in his hand, it was a bit like aluminum alloy, which he didn't know very well, but it was long enough, and it should be quite strong.

You might be able to use the 'leverage principle' to pry those annoying planks off, or...

Holding this long and wide sign, Yu Siqi looked at the classrooms on the first floor. In fact, it stands to reason that now that he already has the tools, he can just find a wooden board that is pleasing to the eye and start working. But he had a bold idea in his heart, and the figure that might have appeared in front of the multimedia classroom always haunted him. So much so that he had no interest in the other classrooms at all, and planned to go straight to the 'theme'.

Stuck the sign diagonally upwards into the gap between the wooden boards, and Yu Siqi raised his hands outward. 'Rattle', the sound of wood and nails loosening, proved that his idea worked, and he repeated it a few more times.

Finally, under the premise of his repeated operation, the wooden planks in front of the door of the multimedia classroom were all pried down by Yu Siqi.

Looking at the sign that had been almost completely deformed, Yu Siqi felt that this thing had fulfilled its responsibility of 'its', so he casually threw it aside.

Some of the dark green doors were now standing in front of him, and with a slight push, he could tell what was inside.

He held a flashlight in his left hand and a dagger in his right hand. After flicking the satchel back, Yu Siqi took a deep breath and pushed open the door of the classroom he had always cared about.

The structure of the auditorium was dim and damp, and nearly a hundred chairs that could be flipped were artificially moved to the position against the wall. Directly in front of the entrance, a thick wire hung from the ceiling, and at the end of the wire, a long-rotting corpse and a chair that had been kicked down were tightly fastened.

Yu Siqi's first reaction when he saw this scene was, did he break into a 'self-hanging scene'? Judging by the picture given so far, it is very likely that this is the case. But what about the wooden planks outside, if the deceased hanged himself with wires in the multimedia classroom, he would not have been able to seal all the doors and windows with his ghost.

The doors and windows are sealed, and it should have nothing to do with the deceased, hey... More and more puzzles haunted him, and he was now desperate to know what was going on here, and why there were so many things that didn't make sense. If only Father Ann were here, he might have been able to relax a lot with him.

However, on second thought, over-reliance on others is not necessarily a good thing. Besides, if I can solve the puzzle by myself, the satisfaction will probably be no worse than any experience.

After confirming that there was no extra space and hidden place to hide anything in this multimedia classroom, Yu Siqi put away the dagger and began to explore here with confidence. At the same time, he also brought in the pile of planks that he had unloaded at the door, and used his lame fire-making skills to make a campfire.

The rise in temperature not only allowed Yu Siqi to dispel the chill around him, but also illuminated the dim multimedia classroom. Looking closer, Yu Siqi found that the corpse was much more corrupted than the one he had seen before. In particular, the soft tissues of the face and joints even showed white bones, which surprised him.

Although he had not learned any knowledge in this area, based on his shallow understanding, he could almost deduce that the deceased must have died earlier than the previous 'unlucky bastard' who was bitten to death by the 'wild dog'.

The deceased was dressed more elaborately and looked like a good suit. And judging by the only remaining hair and facial contours, as well as his figure, this is definitely an elderly man. A teacher or a staff member, or a parent.

After paying a little homage to the dead, Yu Siqi began to turn up the pockets of the 'dead'. Soon, he pulled out a bulging men's wallet from the pocket of the inner lining of his jacket.

When I opened it, I saw that there was a depleted fruit phone, a bunch of keys, some small paper and pencils, and a credit card. There was nothing that could reveal the identity of the deceased, which made Yu Siqi somewhat disappointed. You know, he didn't dig into other people's pockets for the sake of his mobile phone, especially the pockets of the 'dead man'.

But thinking that this guy won't need this thing in his life, and he may be obliged to bring things, Yu Siqi's hand unconsciously stuffed his wallet into his satchel, and stood up pretending that nothing had happened.

The strangulation marks on the deceased's neck, as well as the chair he kicked and the wires hanging down, basically showed that this guy hanged himself, but since there was no clue to his identity, Yu Siqi couldn't find the reason why this guy chose to end his life here on the corpse.

Looking away, the most conspicuous ones are naturally the blackboards that have been hastily wiped. What was written on it was almost impossible to make out now, but judging by the scribbled scratches, the person who did it must have been in a hurry.

Could it be the deceased himself? So why was he in such a hurry? Aren't you in a hurry to report to Hades? It's possible, but it's not very likely. Well, assuming he is in a hurry to seek death, then what about the reason?

Everything has a cause and effect, and don't you need to find out the reason now?

With this doubt and persistence, Yu Siqi found a strange phenomenon in the trash can in the corner.

Although there is nothing out of the ordinary, it is interesting that the trash cans in the multimedia classroom are filled with torn ribbons and balloons when the lights are all in place at the entrance of the school and in the corridors.

Did the deceased do it again? Or is there someone else doing this?

As Yu Siqi explored deeply, more and more similar doubts filled his brain.

For example, he even found each class's celebration signs in the trash, and the celebration signs that should have been posted outside each classroom were put into a tote bag and stuffed into the trash can.

For another example, Yu Siqi found a teaching notebook torn into several copies in the innermost part of the lower level of the lecture hall. After hours of hard work by the 'puzzle master' Yu Siqi, he finally understood all the contents inside. Most of them are filled with various types of mathematical formulas, as well as teaching philosophies, and the last few pages repeatedly say "It's all my fault".

Although Yu Siqi's feet were slightly numb from standing for several hours, he was still very satisfied with the information he had obtained in exchange for such hard work. Especially after carefully analyzing the contents of the note, Yu Siqi realized that the owner of the note was most likely the guy who hanged himself and was also the acting principal of the school.
