Go up to the third floor, the two of them stood in the stairwell, poked their heads upstairs, and separated by a staircase, but also had a rough view of the scene above.

There is a door at the exit of the stairwell. Next to the door is a window, but the window is embedded in the wall, blending in with the wall, and if you touch it, you can see that the so-called window can't be opened at all.

It's not so much a window as a three-dimensional painting on the wall.

On the contrary, the door can be opened, but the appearance of the door is unusually abrupt, the door frames on its left and right sides are pressed and twisted by the wall, the left and the right are embedded in the wall in different directions.

The beam on the roof of the door did not play a role in opening the door, it collapsed and broke, but the concrete held the broken railing firmly in place.

It was the wall that held up the door, and it was like a child's plasticine, pinched out and then inserted into the stick.

The two of them walked upstairs, the footsteps in the stairwell echoed in the room, and they could be heard clearly, the place was so quiet that there were bursts of pulsating sound in the air.

When the environment was extremely quiet, when there was no even insect chirping in the air, the hearts of the two began to feel a burst of depression.

Like a big hand, it grabbed the heart and clenched it tightly and anchored the depression.

They walked to the door, and somehow, the two began to exchange sign language.

"Do you want to go in?" Jiang Wan asked.

He nodded, and as he tried to pull the twisted and broken door open, he didn't feel any resistance.

The door opened, and the world inside appeared in front of the two of them.

“level 2。”

Somehow, a word popped up in his heart, he looked at the space in front of him, and the moment he looked back, he realized one thing in his heart: "This is a brand new space...... It's going to be a dangerous world. ”

He frowned slightly, and looked back into the room.

As far as the eye can see, the room is extremely ordinary.

The two of them hunched over and entered the room together, and in the room, there was a rectangular doorway on the left and right, and behind the door there was nothing visible, and a layer of black things was in the way, pure black, the same thing as the imagination, and abstract things were in the way.

In the center of the room, a long table and chair were placed in the center, and on that table, it was divided into six sections, each with flowers, books, and a calculator.

When they got closer, they saw that each of the books on the table was the same, and the calculators were all in the same place, as if they were the same person, without different habits, and put everything in the same place.

He glanced down at the table and pulled out the chair under it.

The chair was made of wood, with a thick layer of lacquer.

But under the reflective wood paint, the wood was permeated with red and black, and he reached out and touched it, and the layer of wood paint was extraordinarily slippery.

Has anyone really sat on this? He couldn't help but wonder about it. He looked down and saw a small patch of yellowish paper under the table, through a small crack in the table.

He reached out and picked at it, and the note fell into his hand, the handwriting on the note trembled, he looked up, took a pen from the table, opened the cap, and imitated writing on the palm of his hand.

"What is this?" Jiang Wan came back to her senses, she walked to Chen Qing's side, and frowned at the words on the note.

On the sticky note, there are three simple lines of text, which may also be called "rules", but the words on the sticky note are too simple to be believed.

She looked at Chen Qing, and the other party's brows were also furrowed, thinking that she had the same doubts.

"It's too simple...... And ......" he looked at the words in his hand, a little hesitant.

"You can't be distracted during working hours.

Door-to-door visits are not allowed during working hours.

Lights are not allowed to be turned on during working hours.

Working hours must be unconditionally in accordance with the orders of the superior. ”

On the sticky notes, there are only these simple four lines.

It's easy to say that you comply, but here's the problem...... Is the message on this sticky note real?

He looked up, his gaze looking around him again.

In the center of the room, in addition to the long horizontal table, there is a separate table.

There were no other books on that table, which also caused it to be impossible to see the table in the first place at the entrance position.

Chen Qing looked at Jiang Wan, flicked the note in his hand and said, "This may be the rule of the second floor...... But the problem is that we don't know if it's true or not.

I think it is credible to leave it in Zhang Lan's room, because Zhang Lan's room may also be an entity in the Overworld, and in the Backrooms...... I don't think they can just go into the Overworld. ”

"Why?" Jiang Wan was a little puzzled: "Obviously, two of them have already escaped." ”

"That's why I think it's impossible." Chen Qing shook his head and continued to explain: "It's very simple, if every physical creature could leave the Backrooms at will, then the main world should have been destroyed a long time ago. According to Bu Zhaozhao's inference, these creatures may have existed for the same age as the earth, and you humans have developed for 2,000 years, but what about 2,000 years ago?

Secondly, it is also a matter of probability. We know that the event of an entity escaping the Backrooms is a small probability, so I don't think there will be a second or third time when the small probability event has already occurred. ”

Jiang Wan frowned when she heard this: "But you are equivalent to gambling." ”

"Gambling......" Chen Qing smiled, but shook his head: "No." It's not gambling, it's probability, it's math, it's the truth you can rely on in the universe. ”
