After the proving ground came to the world

Chapter 2 Endless Stairs 2
Lu Ning chuckled twice: "I can see it from reading novels. If I was really a boss, my grades would not have been hovering around 70 or so without making any progress. If you want to talk about bosses, I think Mo Ran is the best." , every time the exam is more than 90, a college bully, so terrifying!"

Wang Moran, who was caught by the cue, raised his head to look at them: "Okay, don't talk about this for now. Let me talk about some of my reasoning."

The others listened obediently.

Wang Moran looked serious, and said quietly: "Have you heard of the Penrose Staircase?"

Lu Ning (pretty face): "No."

Su Qian (curious face): "No."

Wang Moran sighed helplessly: "Actually—"

Cheng Buyu: "I know."

The three of them who were used to being scared shuddered reflexively, and looked at Cheng Buyu who had just spoken.

Su Qian: "Oh my god! Fortunately, I've gotten used to being scared in the past two years. But don't say a word, why did your sense of presence weaken so strongly! We could still feel your presence before."

Cheng Buyu's stiff face was slightly happy: "I don't know. But after entering the dungeon, I feel that I can hide myself better."

Su Qian looked at her without words: "Indeed, you hide so much that you don't feel like you anymore."

Cheng Buyu rolled his eyes and smiled.

Lu Ning clapped his hands twice and brought back the topic.

"Shut up, let me tell you, what is this staircase?"

When it came to business, Cheng Buyu restrained his smile.

"This is a well-known paradox in geometry.

Refers to a ladder that always goes up or down but never ends.

It is never possible to find the highest point or the lowest point on this ladder.

Just like the well-known Mobius ring, it goes back and forth and cannot find the exit. "

"Normally such stairs cannot exist in three dimensions."

Su Qian barely understood: "So, this means we can't get out, right? We are trapped here forever, right?"

Wang Moran heard the trembling in Su Qian's ending voice, and hugged her shoulder comfortingly: "Don't worry, we will go out."

Lu Ning thought for a while and said, "Actually, the results of this theory are not applicable to our current situation. The place we are in now is not a purely realistic place.

It has many possibilities.

So, girls, let's find clues!

If it was as silent as he said, there should only be these few stairs here, and the clues should be easy to find. "

The other three nodded in agreement.

Only by taking action will there be a chance to leave here.

Lu Ning was the first to walk up the stairs. She was going down. Going downstairs was much easier than going up.

Lu Ning kept talking about the Penrose stairs that Cheng Buyu had just mentioned. To verify, she took out her hair tie and tied it to the handrail of the stairs.

After about 5 minutes, the four of Lu Ning saw the goose yellow hair band tied to the armrest at the beginning.

The four people who had been psychologically prepared for a long time did not panic, but returned to the starting point.

This time they need to find clues on the stairs.

The four searched for clues separately.

Lu Ning carefully observed the steps, handrails, walls, and the white mist under the stairs.

Soon, Lu Ning found the dried blood on the steps.

If he hadn't observed it carefully, Lu Ning would have thought it was accidentally splashed paint.

Lu Ning walked in the direction where the blood splattered, and she was a little puzzled when she saw the blood splatter, which had increased significantly but was still scarce.

The amount of bleeding here is too little!
It seems to be the level of scratching the palm of your hand.

Or, did the blood go elsewhere?
Lu Ning conceived in his mind that the pooled blood was on the side of the handrail of the stairs, so...

Lu Ning squatted down, leaned his head between the two connecting sticks, and looked down.

For a moment, Lu Ning's eyes widened, his voice was stuck in his throat and he couldn't make a sound.

She felt as if she had seen hell!

As far as she could see, there was a human face.

A face about to rot.

Lu Ning backed away fiercely, knocking her body against the wall, and the severe pain pulled back her consciousness that was about to slacken.

She checked her mental value at the moment: 63
