"The person hiding in the sixth compartment is Fan Yu's father!" Before reading the note, Chen Ge had never thought in this direction: "It seems that Fan Yu's aunt has concealed something very important."

When Chen Ge speculated on the murderer before, he lacked a very important link, that is, the motive for the murder. Now the appearance of these notes has pointed out the direction for Chen Ge.

"There are three notes in total, each with a different handwriting. This means that at least three people know about the dirty things Teacher Fan has done. This should not be a false accusation or malicious intimidation."

Chen Ge did not touch the note in the book because too much time had passed and the paper was very fragile. He was worried that he would destroy this crucial evidence.

"The handwriting on the paper is very clear, there is no deliberate concealment. Teacher Fan left these three notes probably to catch these three students by comparing the handwriting. After all, Muyang Middle School is not very big, and he can use the convenience of his position. He can check the handwriting of all students in three days."

Chen Ge wrote down the contents of the note. In fact, he was also very curious about how these three students discovered the secret in the cubicle: "Are they all victims? But judging from the tone between the lines, it doesn't seem like that, especially the last sentence. If you don't want to leave, then stay forever. This doesn't sound like something a victim would say at all."

The message conveyed by the three notes was very strong, but Chen Ge thought the demands were very frivolous. The correct way to deal with the behavior of Fan Yu's father should be to call the police and let him accept legal sanctions, rather than a so-called public apology, because once some things are made public, they will cause secondary harm to the victims and expose their inner pain to the public.

"The content on the note does seem to be written by students. Could it be that they were the ones who threw Teacher Fan into the well?" The motive for murder was there, but the means and time did not match. Two adults disappeared that night. They wanted to get rid of the two adults silently and cover up the scene without leaving any traces. This did not seem like something a few students could do.

"I must have overlooked something." Chen Ge tried to think from the perspective of Fan Yu's father.

It is impossible for Fan Yu's father to make a public apology. Once the matter is exposed, he will be ruined and will also face legal sanctions. He has made a mistake before coming to Muyang Middle School. If he makes trouble again, he will be a repeat offender and will be punished more severely.

Fan Yu's father must have known all this, so he saved the note, hoping to find the student who threatened him by comparing the handwriting. However, from the results, he found nothing after three days of searching.

"To summarize what we know, three pieces of paper were written by different people. Teacher Fan compared the handwriting of everyone in the school and found none. These three people also discovered the secret of the sixth compartment. The strange thing is that they did not call the police or inform the school. Instead, they used the most ineffective and easiest way to expose themselves, which was to threaten Teacher Fan directly. Last but not least, the contents of the paper really came true."

These three points are what Chen Ge thinks are unreasonable. Putting them together, three people who could not be found in the school discovered the secret of Teacher Fan's peeping, and after warning Teacher Fan to no avail, they made him disappear.

"There is basically no one who can meet all three of these requirements at the same time." Chen Ge already had an idea of ​​who the murderer was, but he was not sure yet.

"The note mentioned a girl. They wanted Fan Yu's father to apologize to that girl. As long as I can find her, many problems can be solved." After recording everything with the live camera, Chen Ge closed the book and put it back where it was.

"These notes were stuck in the book. If I hadn't paid special attention and searched the drawer, I would have missed them. It seems that if I want to find out the cause and effect, I still have to start with the details." Chen Ge left the mathematics office and carefully searched the other rooms on the second floor, but unfortunately there was no other gain.

"It's already ten thirty. If we continue like this, the remaining two side quests will be difficult to complete." Chen Ge came out of the office building with a flashlight. He searched for a well in the school in the heavy rain, but he couldn't find one after an hour.

"Where's the well? There's no way the black phone could have gone wrong!" Chen Ge ran all over the campus but couldn't find the well. His shoes and pants were soaked, and he looked a little embarrassed.

"There is only half an hour left until midnight, so let's put the deep well mission aside for now." Chen Ge grabbed the brim of his raincoat and walked towards the teaching building with his head down. He wanted to go to the last classroom before midnight. If the classroom mission was also difficult to complete, then he would be ready to run away.

Water got into my shoes, and my steps felt heavy when I walked. Every step I took left a shoe print on the ground.

After entering the teaching building, Chen Ge went straight to the last classroom. Since he was already there, it would not be his style not to go in and take a look.

Standing outside the window and looking inside, there was only the desk in the middle of the classroom with textbooks, paper and pens on it, which felt very out of place.

“It does look very weird.”

The original site of Muyang Middle School was a crematorium. Chen Ge had seen this mentioned in some posts online. Some people said that the last classroom corresponded to the place where corpses were kept in the crematorium, and it was filled with heavy negative energy, so the old principal locked this classroom.

Others said that when a class from Muyang Middle School went out for a picnic, the bus had a traffic accident and many people died. The students in this class always came back for class, so they had to vacate this classroom.

The last statement is more inspiring. Before Muyang Middle School was closed, it was the worst in all middle schools in Jiujiang, and its average student scores were the lowest. In order to change this situation, the school teachers suggested dividing the classes into good and bad classes according to their scores, with the classes with worse scores being placed further back. However, this proposal was rejected by the old principal, who locked the last classroom to encourage students that no one is born to be the last, and it is wrong to label them as good or bad.

There are many legends about the last classroom of Muyang Middle School. Chen Ge only remembered the three most discussed ones.

He confirmed the time again, and at 11:36 pm, he pried open the door of the last classroom and entered.

Chen Ge walked quickly. His purpose was clear: to take a closer look at the things on the middle table.

When he first entered the classroom, he didn't feel any difference from outside, just a little quieter.

Coming to the middle desk, Chen Ge looked through the textbooks and white paper. There was nothing on them. When he picked up the textbook, he suddenly found a lot of words carved on the wooden table.
