The first cancer in the world of immortality

Chapter 97 Ancient Ruins: Penrose Staircase

Ye Zijin patted Xia Ying's little head to comfort the nervous little girl.

Then he said, "Everyone, take out all the fairy coins that were distributed to you just now, and put them in front of me."

Everyone took out the fairy coins, Ye Zijin felt it carefully, and nodded.

"Brother, what are these fairy coins used for?" Jiu Zhongyue asked curiously.

"In the dark space, after walking for so long, I haven't encountered any danger." Ye Zijin explained simply: "So I guess, some events hidden here may have been triggered, but we didn't perceive it. .”

"And in the dark space, it is very possible to trigger the 'true and false substitute' event. That is to say, there is likely to be something else mixed in, pretending to be someone in the team, waiting for the opportunity."

"It's a standard plot in horror novels, after all."

"Well……"

Although he didn't quite understand some of the nouns, Jiu Zhongyue already understood the general meaning of Ye Zijin.

"So, these fairy coins you issued have been specially processed by you? If someone of us is replaced, when you check the fairy coins, you can find something wrong?"

"That's right. But after the investigation just now, this kind of thing didn't happen."

Ye Zijin glanced at Jiu Zhongyue appreciatively: "Sure enough, you don't know what you look like."

"Hmph, that is."

Jiu Zhongyue proudly raised her head.

Meng Zhongxian stood beside her and calmly glanced at her complacent sister: "Big idiot, you have been ridiculed."

"...Huh? Who, who dares to mock me!" Jiu Zhongyue stared, and her smile disappeared instantly.

But Ye Zijin didn't have time to care about these two brats.

Now he is thinking about the problem of this weird space.

"If you guessed correctly..."

After a moment of contemplation, Ye Zijin said slowly, "This is probably the legendary Staircase of Penrose."

"Penrose Stairs?" Everyone was confused.

Ye Zijin sighed softly, and once again gave everyone a simple science popularization.

The Penrose Staircase, which is a combination of four staircases.

The four staircases are connected at the four corners, but each staircase presents the same state—going down at the same time, or going up at the same time.

Therefore, the Penrose ladder can be said to be a ladder of infinite extension and development.

"how is this possible?!"

Jiu Zhongyue said: "For now, if every staircase extends downward, then our height should also drop a lot."

"How could it be possible to return to the previous height, the previous place?!"

Ye Zijin did not answer, and his eyes were full of doubts.

The Penrose ladder was proposed by the famous British mathematical physicist Professor Penrose.This kind of ladder comes from the optical illusion that occurs when a three-dimensional object is depicted on a two-dimensional plane.

And everyone has already confirmed that the Penrose Staircase cannot appear in the three-dimensional space.

However, isn't the place where I am now the inside of the Penrose Staircase?
"Xiaoyu, attack the wall."

Ye Zijin had no choice but to try all the possibilities.

Mu Xiaoyu nodded, raising the long sword in her hand.

The sword light flashed, and the sword energy was vertical and horizontal.However, this seemingly dilapidated stone wall has not been cut out of the slightest trace.

"Attack the other wall!"

No exception.

"Attack the top of the head!"

No exception.

"Bring a shovel and dig the ground!"

Can't dig at all.

"Turn around, I'm going to pee."

Everyone: "???"

"I don't believe that a group of living people can still be trapped to death in a staircase."

"Wen Liang, why are you turning around? Take off your pants, go pee on the opposite side."

Everyone: "..."

……

"Oh, just wait for the result."

Ye Zijin let out a long sigh.

He mixed drinking water with his own urine and let it flow down the steps.

If this is really the Penrose Staircase, according to the law of its infinite extension, soon, I and others will see the continuous flow of urine mixture from behind.

After about 10 minutes, a wisp of liquid suddenly flowed down the steps behind him.

Wen Liang, who was standing at the back, hastily stepped back a few steps to avoid the seemingly clear liquid.

"Um……"

Ye Zijin was stained with some liquid, and sniffed it with the tip of his nose: "It smells like my urine. It's not another liquid that has been replaced by someone."

Everyone: "Uh-"

"In other words, are these liquids really going down without any external force, and finally come back from behind us..."

"Could it be that this is really the Penrose Staircase with no exit?"

"No, it's not right. If there is really no exit here, then why would there be a mysterious call in my heart, guiding me to come here..."

While washing his hands with drinking water, Ye Zijin fell into deep thought.

After a long time, he suddenly thought of something, and muttered to himself: "Penrose Staircase...space paradox...paradox...unreasonable state when being observed..."

Ye Zijin suddenly trembled, and hurried forward.

"Hey, Zijin, slow down!"

The partners next to him hurriedly followed.

Ye Zijin quickly ran to the first corner, which was the corner closest to her.

Looking at it with the light of the torch, there was a not-so-thick water stain on the ground.

After observing for a while, Ye Zijin ran forward again, and soon came to the second corner.

On the ground at the second corner, there were no longer fine water stains, but a pool of unevenly distributed wet water marks.

"Heh heh heh...hahahaha! I understand, I understand everything!"

The corners of Ye Zijin's mouth gradually opened.In his eyes, the brilliance of confidence has also been restored!
"What do you understand?" Jiu Zhongyue asked hastily.

Ye Zijin laughed loudly: "The Penrose Staircase, this is a spatial paradox that cannot appear under visible conditions."

"But what about when part of the ladder is not visible?"

"It can be seen from the imprints of these water flows that these liquids are not moving in a uniformly accelerated motion. They are subjected to other resistance in the middle, causing the liquid to scatter and divert, resulting in large irregular water spots!"

"In other words, this so-called Penrose Staircase is not standing still!"

Jiu Zhongyue took a deep breath: "Hiss—it turned out to be like this!"

Ye Zijin smiled and said, "Understood?"

Jiu Zhongyue: "I don't understand."

Ye Zijin: "???"

Then what are you yelling about?
Jiu Zhongyue chuckled: "It just sounds like it's very powerful."

Ye Zijin: "..."

In fact, the principle of this mechanism is very simple.

When Ye Zijin and the others circled around these stairs, at any moment, there would always be at least two steps that were invisible.

In other words, the maximum number of stairs they observed at the same time was two, that is, when they stood at the corner.

So where they can't observe, the other two stairs must be stationary?

The Penrose Staircase is a paradox in terms of dimensions, and its own nature determines that it cannot appear in this dimension.

However, if it is to deliberately create an atmosphere like the Penrose Stairs by silently changing the invisible stairs...

In this mysterious world of cultivating immortals, this method must be extremely simple!

Seeing that everyone was still full of doubts, Ye Zijin shook his head, did not explain too much, but directly issued an order: "You two are standing here and don't move."

"Jiu Zhongyue stares at the place where the stairs go down, and Meng Zhongxian stares at the place where the stairs go up, which is the direction we just walked down."

"Remember, your eyes must always be fixed on your respective directions, and never divert your eyes! Absolutely!"

The sisters looked puzzled.But before they opened their mouths to ask, Ye Zijin had already led others to the next corner.

Helpless, they could only whisper to each other while following Ye Zijin's method.

"Wen Liang Xia Ying, you are standing at this corner, keeping your eyes on the direction of the stairs going down. Just like the pair of sisters, never avert your eyes!"

"Okay." Wen Liang and Xia Ying nodded obediently.

Although Ye Zijin's usual painting style is a bit broken, but I have to say that he is still very reliable at critical moments.

"call……"

Ye Zijin let out a long sigh of relief, and walked towards the next corner.

While walking, he said to his side: "Xiaoyu, get ready for battle."

"Uh-huh!"

With the long sword in hand, Mu Xiaoyu stared vigilantly at the corner not far ahead.

"Hmph, no matter who is playing tricks..."

Ye Zijin smiled lowly, took the last step, and stood at the third corner: "This Penrose staircase, break it for me!"

At this moment, in the Penrose Stairs consisting of four staircases, every staircase is exposed to someone's sight!

In other words, the entire ladder is in a "visible state"!
In the visible state, the Penrose Staircase is a paradox, a completely impossible thing to exist!

After taking the last step, Ye Zijin turned her head and looked at the last staircase that she had walked down many times.

There, it is no longer the infinitely downward-stretching ladder that everyone has seen before.

Instead, there is a staircase extending upwards.

At the end of the stairs, there is a small door.Inside the door, the faint purple light was swirling and flowing continuously.

This is the familiar space channel!

The Penrose Staircase has been broken!

　Suddenly realized that I forgot to make a preview of this article.

　　Then, the remedial measure is... not to do it in the future~
