Xing Ziliang was very depressed at the moment, the most important thing was not that he couldn't walk out of the stone stairs, but that his stomach was screaming. Pen ~ fun ~ pavilion www.biquge.info

During the foundation building period, it is not possible to carry out long-term valley reclamation, but it can last for a long time longer than ordinary people, but the physiological appetite and hunger still need to be endured.

Xing Ziliang doesn't think he's very smart, so he's now very worried that he really won't be able to get out, and he will starve to death and die of thirst here.

"How can there be a Penrose Ladder in this world, it's not scientific......," he muttered and complained, "No, this world is not scientific in the first place, how can I be superstitious about science?"

"But it stands to reason that the Penrose Staircase can't exist in the three-dimensional world, so there should only be two cases of this stone staircase, one is that a special construction method is used, and the other is that I really encountered a ghost hitting the wall. ”

Xing Ziliang began to recall his knowledge of the Penrose Ladder, remembering that the first time he heard about this famous math paradox was in a math class in high school, when the math teacher accidentally mentioned it.

Although the teacher did not go into detail, he remembered that the teacher also said that in ancient times, there was a stone staircase building similar to the Penrose Steps, which was made by skilled craftsmen, and used visual errors and other means to make people lose in it.

It feels like a simple single staircase, but the actual structure is extremely complex, with many forks and turns, and a variety of clever designs to lure people astray.

It's a pity that the teacher only mentioned it by chance when he was learning geometry at that time, and the specific situation was not clear.

Xing Ziliang looked up and down, thoughtfully, it seems that the existence of corners every ten or so steps is to confuse people, and he keeps spinning in place.

Thinking of something, he got up and went back to the corner below, put the corner of his coat in the corner, and walked up again.

"One, two, three......"

"Sixteen, seventeen, eighteen......"

He counted the steps as he went, and after turning the corner, he began to count again, until he saw the corner of his clothes again, and he was sure that the stairs had indeed been twenty steps all along.

"I made a total of four left turns, which means that I would go back to the same place every eighty steps......"

Xing Ziliang planned to try the methods of cracking one by one, and first chose to close his eyes and count the steps silently.

"If there's a bad optical illusion around the corner that causes me to keep going back and forth, maybe I can try to close my eyes and not look at it so that it doesn't go astray. ”

However, when he walked the eighty steps, he opened his eyes and still saw the corner of the clothes, and everything was in vain.

"But when I closed my eyes just now, I felt a little weird......," Xing Ziliang looked thoughtful.

He thought about it for a long time, but he still couldn't think of why he felt strange, so he simply decided to go again, so he closed his eyes and continued to move forward.

When he returned to square one for the second time, the feeling was clearer.

"There must be something strange about this step, when I close my eyes and walk forward, I lack one of my five senses, and what mystery does my body feel alone that I touch......?"

Now that he had a clue, Xing Ziliang naturally would not give up, and began to keep trying, walking several times with his eyes closed, and each time he walked, he felt that the strangeness was becoming clearer and clearer, but it was always like a thin veil that was difficult to pierce.

But gradually, Xing Ziliang began to notice that this strange feeling did not come from the heart, but from the feeling of the body itself.

He began to look for a way from himself, completely emptying his mind, even giving up on silent counting, and moving forward with only one feeling with his eyes closed.

At first, he either walked two steps less and turned around and hit the wall, or he reached the corner and walked back and slammed directly into the wall.

As the saying goes, if you don't hit the south wall, you won't look back, Xing Ziliang hit the wall one after another and didn't look back, he kept trying, and his braincase was almost blue, but gradually, he actually walked back to the same place just by feeling, and didn't hit the wall once.

After nearly four or five hours of trying, he can even close his eyes and trot a full lap back to where he is.

"My control over the physical body seems to be ......" Xingzi Liang muttered to himself, feeling incredible, and unconsciously, his control over the physical body seemed to be more detailed.

"Have I reached the state of physical perfection......?"

Xing Ziliang was amazed, at this moment he felt that he could feel the different states of his body every second, even the contraction of pores, and there was an instinct in his body.

Xing Ziliang knew that there was a realm in martial arts, which was called subtlety.

But there is a difference in subtlety, one is the spiritual subtlety, the control of one's own thoughts, etc., is to transform the subtlety, which is an extremely profound realm.

The other is the subtlety of the physical body, as the name suggests, the physical body reaches a state of extremely sensitive feelings, and has extremely detailed control over itself.

In other words, the physical body also has a memory, which is even different from the nerve reflex, which is a real memory, in short, something similar to the words "who can make perfect".

For example, if someone suddenly hits a judoka on the shoulder, he may directly respond by giving you an over-the-shoulder throw.

Just like the oil seller in a certain story, he can pour oil into the gourd through the round hole in the middle of the copper plate from afar, which is how perfect it is.

When the conditioned reflex of the physical body is combined with the ability to make a skillful combination, it has the realm of reaching the memory of the physical body, that is, the physical body is subtle!

In the original earth, almost no one in modern times could reach this state, even the martial idiot grandfather had only heard of it, and perhaps only ancient times existed.

But in this world, because of the existence of the cultivation avenue, the body opens the sea of knowledge, refines the body and crosses the qi, and the subtlety of the physical body is no longer ethereal, and even at this time, Xingziliang guessed that once he enters the Dan period, depending on his personal situation, he can naturally gradually reach the state of the physical body.

But at this moment, he actually reached this state in advance and comprehended the subtleties of the flesh.

At the same time, Xing Ziliang also understood where the strangeness he had always felt came from.

He almost ignored the fact that since there could be no real Penrose Ladder in the three-dimensional world, why did he still return to the original point when the ladder kept going up.

The strangeness of this stone staircase comes from the fact that it is not flat!

Xing Ziliang can break through the subtle realm of the flesh in the continuous back and forth, which also stems from the strange feeling of the body.

He passed through a total of four corners, and at the fourth corner he returned to the same place, and he could simply divide the stone staircase into four stone stairs from east to south, from south to west, from west to north, and from north to east.

If the stone stairs are ten centimeters high, Xingziliang has walked up a total of two hundred centimeters from east to south, but the problem lies in the three stone stairs behind.

If the passage where each stone staircase is located is regarded as a pipe, and the stone staircase is built in the pipe, then the pipe from east to south is normal, the pipe is inclined upward, and the stone staircase built in it is also upward.

But the three stone stairs behind the corner are within different pipes, and all three pipes are inclined downward, until they also go down two hundred centimeters, and then return to the starting point where the first pipe is.

Although the other three stone stairs appear to be upwards, they have many ingenuity, but in fact each step of the stone staircase is not horizontal, but inclined downward, and the width of the stone staircase is also constantly extended, so that it is built in a larger pipe, with extremely imperceptible gaps, such as only tilting one centimeter, extending the width of one centimeter, such a small difference, it is difficult to feel the change.

Moreover, the three stone stairs are not fixed, each step will sink when he steps on it, which is also a very small gap, but it eases the feeling that he is actually going down.

And the reason why Xing Ziliang felt strange was because he was walking on the upward stone staircase even though it was obviously a downward pipe, and the stone staircase seemed to be upward, but the staircase was inclined downward.

In the process of feeling strange and constantly trying to crack it, his sensitivity to the flesh also formed a kind of exercise, and finally he reached the state of being in the flesh.
