This room looks more like a research room, with bookshelves on both sides of the wall, filled with all kinds of books.

The thunder and screams seemed to be much smaller, and the lights were dim, but fortunately, everyone could see everything here clearly.

The setting of the game is that at this moment, their identities are passers-by who accidentally walked in here. Not only do they have to escape, but they also have to uncover all the secrets here.

Except for the two doors they just walked in, there are no other exits here. They can't go back the same way, so the bookshelf is a very likely clue.

The bookshelf is very high. Xu Yao walked over and pulled out a book to read. He found it was very light. He smiled and waved it at Xia Han, saying, "It's fake."

Some books could not be moved. Li Tianfeng tried to pull them out, but failed.

Xu Yao took down all the movable books and looked at them. He said, "There are wires at the back. It looks like it has a mechanism."

Li Tianfeng said, "You can't dismantle the bookshelf, can you?"

Xu Yao quickly checked all the bookshelves and found that only two rows of books were movable. Li Tianfeng pursed his lips and thought, his eyes wandering around, guessing, "These books..."

Xu Yao had already started to classify the books according to the cover. Li Tianfeng groped for the empty space on the bookshelf and found uneven traces under the shallow dust.

He asked, "Is there a mark on the book?"

Xu Yao picked up a book and showed it to him. There was a circular mark on the back of each book: "Are you talking about this?"

Li Tianfeng used a flashlight to illuminate the mark on it. It was indeed a pattern similar to the circular mark on the book. He said, "It should be based on this pattern."

Suddenly, the light extending from his hand disappeared, and Li Tianfeng Tianfeng's surprised voice rang out: "Hey? Why isn't it lit?"

Xu Yao guessed, "Is it out of power?"

Li Tianfeng fiddled with the bookcase for a few times, then gave up helplessly: "It should be."

Xu Yao wanted to hand him his intercom, but Li Tianfeng waved his hand to refuse: "Just follow the instructions."

He stepped aside and stood, using the light in Xu Yao's hand to see the scene in front of him clearly. At this time, Xu Yao had already quickly put the books on the shelf, with different patterns in different positions, and filled the bookshelf again.

The two stood there and saw the bookshelf slowly move to the sides, revealing a hole, as if leading to darkness.

Li Tianfeng glanced at Xu Yao, who had already raised his flashlight and walked in.

It was an iron ladder that went up vertically to the next floor.

Xu Yao used the flashlight to illuminate the space and saw that it seemed very bright, so bright that he felt dizzy, but this feeling did not affect his climb up, and soon he stood steadily on the ground.

A laboratory, with various test tubes and bottles of medicine on the table, and a thick book spread out with strange words written on it.

Li Tianfeng climbed up closely and saw a door next to it, so he walked towards it.

This was the only room with bright light.

Xu Yao endured the increasingly strong dizziness and studied the book on the table carefully. Li Tianfeng pushed open the door next to him, and a surprised voice suddenly rang out: "Xu Yao!"

Xu Yao followed and saw a baby carriage in the door, with a toy doll lying inside, the child's eyes were closed, and the room suddenly rang with the child's giggling. Although I knew it was fake, it felt creepy.

Suddenly, all the lights in the room went out, and only a huge black shadow rose up on the wall where the baby carriage was leaning against.

Li Tianfeng waved to Xu Yao: "Where's the flashlight?"

Xu Yao ran over to illuminate him. Li Tianfeng said: "Is there anything wrong with the stroller?"

He said this but slowly stepped back half a step. Xu Yao raised the flashlight and walked forward to the stroller to check carefully. He found that there were also wires under the stroller. Just as he was about to turn around and call Li Tianfeng to come over, he heard a muffled "click" from behind.

All the lights went out in an instant, and he was trapped in the darkness, and the door was locked.

Li Tianfeng stood behind the door. Xu Yao couldn't see his expression at the moment, but he could imagine the expression on his face at the moment.

He should be smiling, his smile is calm and elegant, just like a certain moment in the past.

Li Tianfeng's voice came from the intercom: "Xu Yao, you lose."

Xu Yao pulled the door twice, and suddenly felt the sound of air flow from somewhere. White smoke quickly filled the room. It was colorless and odorless dry ice, but it felt suffocating.

All the background sounds stopped abruptly, and someone said: "The game is over."

According to the story of the secret room, the only way to get out of here is to exchange the life of a companion, or, before the door is closed and the "poison gas" is released, find the clues in the stroller and open the door.

However, Li Tianfeng won.

Xu Yao reacted quickly: "Your intercom has always been charged!"

Li Tianfeng said: "Yes."

Xu Yao breathed hard, the pure black space made him feel extremely uncomfortable. The bloodiest and most profound memories of the past instantly flooded into his mind. He tried hard to speak: "You lied to me?"

Li Tianfeng said again: "This is just a game, isn't it?"

Xu Yao said: "Then what? Like killing others, killing me is also part of your game?"

Li Tianfeng shook his head and stared at the door, his eyes tangled but fixed. Chong: "How I wish the one who abandoned me wasn't you..."

Xu Yao fell down beside the stroller, leaned against it, and said slowly: "Even if I said I didn't abandon you, would everything be different?"

Li Tianfeng said calmly: "No, I must avenge myself."

Xu Yao looked into the endless darkness and asked: "Even if it makes me an unforgivable person?"

Li Tianfeng turned his back, his eyes without hesitation: "Yes."

Xu Yao closed his eyes: "Li Tianfeng, you disappoint me so much."

Li Tianfeng, wearing a gas mask, walked slowly into the room.

"Speaking of disappointment, this is not as disappointing as the disappointment you brought me when you abandoned me."

Xu Yao felt that his whole body was paralyzed and his head hurt as if it was about to explode.

Li Tianfeng directly threw a pair of boxing gloves to Xu Yao, put them on himself, looked at him provocatively, and said:

"Xu Yao, let's fight."

Xu Yao couldn't help but sneer. This was not a fair match at all. Under such conditions, Li Tianfeng was just thinking of ways to punish him.

But Xu Yao would never beg for mercy. He would fight to the death and meet the challenge with all his strength.

He slowly stood up with all his strength and shot a sinister look over.

"Okay, let's have a good fight."
