Hush!don't open the door for him

As soon as Fang Yin entered the classroom, he ran into Qin Pinggui with a serious face. After seeing him come back intact, Qin Pinggui's expression relaxed a lot.

"How is it?" he asked in a low voice, looking concerned.

Fang Yin was unmoved by his useless concern, without any emotion on his face, just nodded and said perfunctorily: "It's good."

On the contrary, Mao Chengcheng chattered, shaking off all the things that they were surrounded by people in the toilet just now.

"They looked so vicious and terrifying. Fortunately, the door was not opened. I think we still have to follow the class rules Fang Yin said. It's too scary, too scary." Mao Chengcheng patted his chest with a look of lingering fear.

Fang Yin didn't greet them, just pulled away the chair in front of Xiaoxiao, and sat down in front of her.

The place where the name was originally written on the small desk has been painted out by her. It seems that she doesn't want Fang Yin and the others to know her real name.

She was writing something at her desk, which looked like an exercise book.Fang Yin suddenly sat in front of her, his tall figure covering the light.As if she had been frightened suddenly, she raised her head and shrank back for a moment, then realized that she had lost her composure, and quickly adjusted her state and relaxed.

As if Fang Yin didn't see her abnormal state, he looked at Xiao Xiao's wet almond eyes and asked, "You said you can ask you any questions, right?"

Little nod.

"Do you have siblings?"

Qin Pinggui and the others didn't know what Fang Yin was doing, so they just stood by and looked at it stupidly.

Xiao Xiao immediately denied it: "No."

Seeing her determined look, Fang Yin smiled and said nothing.

Xiao Xiao couldn't sit still, she narrowed her eyes slightly, looking a little dangerous: "Why do you ask that?"

The atmosphere was a little stagnant, Fang Yin faintly smelled the danger, but he didn't realize it, and made a very innocent gesture to look at Xiaoxiao: "Just ask. Why are you nervous?"

Xiao Xiao looked at him and said nothing, but the expression on his face was not so good-looking, and he was not at all as comfortable as he was at first.The two looked at each other for a moment, Xiao Xiao suddenly smiled, and she said, "It's not me who should be nervous."

After she finished speaking, she ignored Fang Yin, lowered her head and continued working on the exercise book in her hand.

Ten minutes later, the class bell rang again. This was a self-study class.Fang Yin took out the exercise book from his schoolbag and started writing, as if he was really a student.

Qin Pinggui on the side frowned. He held down Fang Yin's pen-holding hand, abruptly interrupted his movements, looked at Fang Yin worriedly and asked, "What's the matter with you? Since you arrived After the fourth floor, you become very wrong."

"Really?" Fang Yin didn't care. He asked, "Do you know what Zhao Shuyi did before the fog fell?"

The question he asked Qin Zinggui was exactly the same as he had asked Mao Chengcheng in the corridor before.

"Doctor, when I saw her for the first time, she was wearing a white coat." Qin Pinggui thought for a while and said.

Fang Yin nodded, pulled out his hand lightly, and said, "Really. I suspect... between us, someone is a fake."

Qin Pinggui immediately understood what he meant: "You doubt Zhao Shuyi?"

"Guess." Fang Yin said, sketched in the exercise book, and wrote down a quadratic function problem, "reasonable speculation, reasonable doubt."

Qin Pinggui kept staring at Fang Yin, but Fang Yin ignored him.

He was doing quadratic function questions under his pen, but he was circling the clues he got all afternoon quickly in his mind. He already had some obvious eyebrows, but he couldn't be sure, and needed some evidence.

But it's still early.

According to Li Xingxing's handbook, it can be deduced that the duration of illusions on the first to third floors is about three days, and the longest can reach four days.Now Fang Yin has just entered the illusion for a short afternoon, it is still early.

The light on the fourth floor of the teaching building has been dizzy, and there is no way to judge the time by the sky.And Fang Yin didn't have any usable timing tools.The classroom is so dilapidated that there is not even a clock. He can only rely on the one-to-one correspondence between the course content of each class and the class schedule to obtain a vague concept of time.

There is no evening self-study in No. 05 Middle School of the city.The last class ends at around 30:[-]. Through asking a little question, he learns that the lights-off time of the dormitory building is ten o'clock in the evening, which means that he has four and a half hours of free time.

Fang Yin took advantage of these four and a half hours to get a rough idea of ​​the terrain of No. [-] Middle School in the city.The dormitory building, the cafeteria, and the teaching building each have five floors.

And each floor of each building has a one-to-one correspondence.The first floor of the dormitory building was also brand new, but the fourth floor was dark and dilapidated, with most rooms empty and sealed.

Fang Yin does not know the specific meaning of these clues for the time being.You can only temporarily maintain a skeptical attitude.

He dumped Qin Pinggui on the pretext of going to the bathroom, and searched the whole dormitory building but couldn't find the bed of the boy who was locked in the bathroom.

He originally guessed that the boy was the one whose name was erased from the class rules, but there was no place for him in the dormitory.But since this is the case, the sixth article in the class rules has no meaning.

Article [-] of the class rules stipulates that you are not allowed to chat with Kou Kou in the dormitory, and Kou Kou is not allowed to respond when talking to you.But if Kou Kou is not a person living in the dormitory, what kind of conditions will trigger this?

The time to turn off the lights came soon, but Fang Yin did not get any useful information.

When I returned to the dormitory, I saw an envelope in kraft paper on my bed.There is a red wax seal on it, showing that it is still unread.

"What is this?" Fang Yin pinched the envelope and asked Qin Pinggui.

The two of them live in the same room.Mao Chengcheng lives next door.

Just now Fang Yin said that when he went out to use the bathroom, Qin Pinggui was the only one left in the room. After he came back, there was such an inexplicable envelope.

Qin Pinggui insisted that he didn't know: "When I came back, it was on the bed, and I had it too."

The content of the envelope is very simple, only three lines.

The first line, don't tell others what's in it.

In the second line, bring your friends to the fourth floor of the teaching building to participate in a small game before eleven o'clock.

In the third line, if your friend does not come, you will be punished in his place.

Tiny... Tiny again.

Whether this Xiaoxiao is that Xiaoxiao, Fang Yin doesn't know yet.

"What was written in your letter?" Fang Yin folded the letter and stuffed it back, shaking Qin Pinggui, and asked.

Qin Pinggui looked at him for two seconds and said, "I want to find Xiaoxiao on the fourth floor of the teaching building. What about you?"

"Same." Fang Yin put the letter in his pocket and said with a smile, "Let's go together."

something wrong.

Or, Qin Pinggui lied, he told Fang Yin false information, so they are safe for the time being.Then there is a high probability that the content of everyone's letter is the same.Here, they don't know anyone, there are only four of each other and a mysterious little girl.Fang Yin is Qin Pinggui's friend, and Qin Pinggui is Fang Yin's friend.No matter who takes whoever goes with them, the so-called punishment cannot be avoided.

Or, the content of Qin Pinggui's letter is different from Fang Yin's, and there is nothing in his letter that cannot say this, then Qin Pinggui is a friend who is about to participate in the game.But what conditions will cause the content of the letters between them to be different?

Fang Yin held the envelope, looking calm, but his mind was spinning fast.

As soon as the words were finished, the dim yellow tungsten lamp on the roof suddenly went out with a "snap".

Lights out.Time to sleep.

The voice of the housekeeper aunt came from the corridor: "Everyone sleep well! Don't let me find out which child is not good."

Fang Yin stood still and did not move.

There were no curtains in the room.Obviously there is no moon and sea of ​​stars in the illusion, but there is light outside at night.The soft, hazy white misty light passing through the cracked glass seemed strangely holy.

The two stood silently for a few seconds before Fang Yin said, "Let's go. Avoid the auntie."

After ten o'clock in the city's No. [-] Middle School, the patrollers changed from the dean to the auntie of the dormitory and the uncle of the guard.

Fang Yin and Qin Pinggui sneaked out of the dormitory together.

At first, I thought that there was no one in the empty campus at night, but I saw two doggy figures like them at the door of the teaching building from a distance. When I got closer, I thought, oh, isn't this an old acquaintance?

"You guys are here too." Mao Chengcheng saw that their eyes lit up, but then he wrinkled his face again, "The door is locked, you can't get in at all."

Zhao Shuyi was not as excited as Mao Chengcheng, and asked them in a low voice, "Have you also received the letter?"

Fang Yin and Qin Pinggui nodded.

The glass door of the teaching building was locked with two iron chains from inside the building, and there was no way to open it.If you break it hard, the glass door can be smashed open, but it must make a lot of noise.

The four were at a loss, but Fang Yin suddenly remembered that there was a small door on the side of the teaching building, which was locked from the outside.

"You know how to do this?" Mao Chengcheng squatted beside Fang Yiner, watching him pick the lock with Zhao Shuyi's one-word card.

While feeling the lock in his hand, Fang Yin said modestly: "I have learned a little bit."

"Why are you learning this?" Mao Chengcheng didn't have the slightest sense of sneaking, and couldn't stop talking for a while.

Fang Yin was worried that they would be discovered if they made too much noise, so he quickly signaled Mao Chengcheng to be quiet, until he successfully opened the lock, and then he explained in a low voice: "I have nothing to do, I have learned a little bit."

Mao Chengcheng was amazed and gave him a thumbs up.

The small door is located on the side of the teaching building, and they need to go through the glass main door to reach the stairwell.Dim light shone on the glass front door, and one could vaguely see someone looking out.

Hair disheveled.

All four of them were taken aback.

is small.

As if aware of something, Xiao Xiao turned around and found four people who couldn't avoid it.

... "How did you get in?" Xiao Xiao asked blankly while holding the key.
