The words on the paper are intermittent, which seems that the writer's mental state is getting worse and worse, but the content that he can read has made Zhou Bai feel extremely strange.

……

Mike would sit up and look at the door every night.

His condition is getting worse and worse. Will he eat him?

Today, Mike still didn't sleep. He just stood at the door. It seemed that he would go out anytime and anywhere. I didn't dare to get up... I felt that he had found the situation.

Open the door, Mike opened the door and went out. I wrapped my quilt tightly and forced myself not to look at the things outside the door.

Mike didn't come back the next day, and another person disappeared. What should we do?

I feel dizzy when I get up every day.

I became more and more sleepy. He kept staring at me in class. I felt that I had been found.

In the morning, I found the paper I put on the door lock fell down. Who moved the door lock last night?

My chest is getting more and more painful. I can feel something inside

I was too tired. I didn't go to class. He came to me.

Everyone will be eaten, and we have lost hope.

He is looking at me. He looks at me through the keyhole at night. He is waiting for me to come out!!!

I decided not to sleep anymore, I can't be eaten!!

It's right not to sleep. I feel better and better

……

Zhou Bai frowned. He was a big man of immortality. Most of the words behind him were meaningless nonsense, and he was a little confused.

Alice asked, "what do you think?"

Zhou Bai glanced at the girl who looked only 12 or 13 years old and said softly, "stay up less and sleep more."

"Not for you." Alice said angrily, "who do you think the 'he' mentioned above is?"

Zhou Bai: "I don't know. There are too few clues. You can say it's you."

Alice curled her lips. "Don't you think the teacher and the whole base are suspicious? I found this diary in the interlayer of the bed board. That person should have slept in my bed before."

Zhou Bai accidentally glanced at each other. A little girl grew up in the environment of underground base, and the whole world outlook was shaped by this environment. It was really not easy to take the initiative to doubt.

However, Zhou Bai didn't plan to discuss anything with a child. He nodded and said, "go to bed early at night. Don't be like him. You'll become a great Luo Jinxian."

Seeing that Zhou Bai was going to leave, Alice kicked her feet angrily, chased up and said, "don't you want to leave the base? Don't you want to go out and have a look? There might be no end of the world outside!"

Seeing that Zhou Bai still ignored himself, Alice said, "BANDU's character has completely changed since last month, as if he had completely changed. He had also read this diary, but when I asked him again, he didn't remember it at all."

Zhou Bai's footsteps paused slightly and looked at Alice: "what else do you know?"

Alice: "in the laboratory on the fifth floor underground, BANDU has been there, and he has changed since he came back. I even suspect that he is not BANDU at all!"

"How did he get to the fifth floor?" Zhou Bai touched his chin and asked, "I asked Aisha. There is fingerprint retrieval at the gate there. Only teachers can go there."

Alice said, "if you want to go out, you need to open the alloy door on the first floor, and if you want to open the alloy door, you must have an electronic card. BANDU and I searched the whole base and couldn't find it. That electronic card can only be in the laboratory.".

We found that a ventilation pipe was connected to the fifth floor of the basement. BANDU and I spent several months cutting the fence inside.

But after BANDU came back from the laboratory that day, it seemed that he had changed and the fence in the ventilation duct had been repaired... "

Alice's face showed a look of fear: "what happened... Did the teacher find us?"

Zhou Bai's eyes showed a thoughtful look: "do you want to go out and have a look?"

"You..."

"Then take me to the vent."

Whether it's the so-called electronic card, the cat related to the auxiliary system, as well as the secrets of the base and the teacher, all seem to be related to the underground laboratory. Zhou Bai decided to go down and have a look in person.

So led by Alice, he found a ventilation duct under the ceiling of the canteen, and then comforted Alice to go back.

That night, looking at Aisha who was sleeping soundly, Zhou Bai quietly got up from the bed.

"Sure enough, I still want to go in the evening."

But the moment he reached out to open the door, his mind couldn't help flashing Aisha's warning before, don't go out at night.

"It's okay. The strange face I saw before is not the cat." Zhou Bai comforted himself, "and I'm a motivated man. Alice and BANDU also cut the ventilation pipe every night. What am I afraid of?"

Out of the room, gently close the door, looking at a dark corridor, Zhou Bai frowned slightly.

Because there is no light in the underground space, now the corridor outside is almost dark, and Zhou Bai finds that he can't see anything at all.

So he had to reach out to the wall and walk towards the canteen in the direction he remembered.

After walking for a while, Zhou Bai couldn't help swallowing his saliva. In the silent and almost absolute darkness, every minute and second was much more painful than expected.

After taking a few steps, Zhou Bai always felt as if something was looking at him in the dark.

Finally came to the canteen, Zhou Bai felt in the direction of the ventilation duct.

In the dark, Zhou Bai's hands felt up inch by inch along the solid wall. His hands were soft, and he actually felt a soft thing.

His heart was startled: "what is this?" The palm of his hand touched the soft thing all the way, and one hand suddenly grabbed Zhou Bai's mouth, which scared him almost to start reading.

"It's me." Alice whispered, "I guess you'll come in the evening. How are you going to get down? I'm going with you this time."

Zhou Bai rolled his eyes, and Alice then said, "this time I must see for myself what's going on. I'll call if you don't take me over..."

"OK, OK, I'll take you there." Zhou Bai said helplessly, "you loosen your hand and pinch my neck."

Alice was stunned and said slowly: "... I didn't pinch your neck."

Zhou Bai's scalp was numb in the dark, and he directly launched the power of the yuan God to push away the palm holding his neck.

Then he reached out and grabbed Alice, looking nervously at the darkness around him.

Alice, who was caught, said in fear, "what's the matter? What happened?"

Zhou Bai: "who is there?"

He looked at a dark space, and the power of the yuan God swept around the surrounding space, but he never felt that there was anyone else.

"Get out of here."

In the silent darkness, no voice answered Zhou Bai's words.
