Everyone gasped, but what Xin said was right, this phenomenon does not conform to objective laws, but the cave where several people are located is not just like this Penlos staircase, which is incomprehensible?

Ke Xin looked at the pattern under her feet and continued: "Se Yami, they have been walking for more than three days, and it stands to reason that they have walked nearly a hundred kilometers away, but we only walked for more than half a day before catching up, what does this mean?" ”

Yun Yanuan also looked at the three-dimensional pattern that could not exist and said in a deep voice: "It proves that they are walking in a circle and going back!" ”

"That's right, they must walk in circles again, and if they go on like this without a clue, they will never be able to get out, and they will not be able to spend their lives!" But my face was full of worry.

Ami Se took a small step forward and said, "However, this is a false proposition, a paradox, something that cannot exist in reality, since it will not exist, how can we walk on it?" This statement is definitely not true, it must be because of the color of the rock wall, the light absorption effect is too strong, causing us to ignore the existence of the exit! ”

Ke Xin pointed to the pattern on the ground and retorted: "You said it doesn't exist, so why can I draw it?" ”

Se Ami pointed to the pattern of the Penlos Staircase and said: "This is painted on a flat surface, there is no height in the 2D world, so it can be visually presented, ignoring the time, we are in 3D space, there is a thickness, this pattern cannot be established, I don't believe your statement, we can never be on the Penlos Staircase." ”

Ke Xin shook his head and said: "Ignoring time, we are not in 3D space, but in 4D space, this is a folded space, one more dimension than the outside, then, the Panloth Staircase seems to be achievable!" ”

"What? 4D space, here is the folding space? Ami Se looked incredulous.

"That's right, this is a folding space, the four of us have discussed it before, but at the time it was just a guess, but after passing through this cave that resembles the Penloth Stairs, I am almost more sure of this conjecture!" Kexin said very seriously.

"I don't see any difference between this and the outside world, how can I identify this speculation?" Ami Se said, shaking her head.

"It's normal that you don't notice the difference, because the limit of our brain is 3D space, and we can't feel it at a higher level, but it doesn't mean that it doesn't exist, such as this Panlos Ladder, which can be realized in a two-dimensional plane, but it can't be established in a three-dimensional plane, but it can be in a four-dimensional space!"

You can talk about it eloquently.

"Well, assuming this is a four-dimensional space, then how did the Panloth Ladder form in the four-dimensional space? The four-dimensional space is also composed of the most basic three-dimensional space, and it also has thickness, how do you realize this impossible paradox? ”

Ami Se is stubborn and insists on not believing in Kexin's conjectures.

Unexpectedly, Se Ami said that Kexin was very happy, this little girl was jealous that people had one more doctorate title than him, but he didn't think that Se Ami should be twenty-seven or eight years old, and Kexin was only twenty-two years old, and the gap between this is not a doctor's title.

"I knew you would think so, I'll explain it to you!" As he spoke, Ke Xin picked up the lower teeth of Candle Jiuyin, soaked in golden snake oil, and divided the original Panlos Staircase into two, drawing a three-dimensional square on both sides.

Two quadrangles of the same size do not fully intersect and fall apart from each other, each leaving a section of space.

"Got it?" But he looked at Ami Se triumphantly and said.

"If that's the case, the Penros Staircase can indeed be represented in a folded space, are we in such a staggered space?" Seami's eyes lit up, and as soon as she saw the picture drawn by Ka Xin, she already understood Ka Xin's thoughts.

But Yun Yanuan and Diana, two people who don't learn and don't know how to understand, Yun Yanuan is still pretending to be reserved, touching her chin there and seeming to be studying, but in fact, she is a mess at all, Diana has no so-called face consideration, and asked directly: "What does this mean?" "This girl is starting to learn Yunya Nuan's Northeast accent.

Ke Xin smiled smugly and pointed to the two quadrants:

"This cave is the junction of two spaces, but it may be naturally formed, or it may be man-made, when the space intersects, the two spaces are staggered by a distance, so that we will go up, but eventually return to the original point, because this upward height has been offset by the staggering of space, which forms a complete Penros Ladder."

After a hearty answer, Yun Yanuan and a few people completely understood her guess and the principle, and couldn't help but be admired by this little girl's head.

"If your guess is correct, then we have found the crux of the problem, but how to solve this game?"

Yun Yanuan looked at Kexin and asked.

Ke Xin looked at the pattern under his feet, thought for a while and said: "If my guess is true, then I have a way to crack it, but it may take some time, but it won't be too long, because I guess that this cave is not as long as I imagined!" ”

"But Lord Xin's orders, Xiao Yunzi obeys!" Yun Yanuan couldn't help but be happy when he heard that he had a way to solve this dead end.

"Yes, yes, hurry up and let us out, it's a big deal to find an entrance to the cliff again, it's really not possible, let's just live here, anyway, there are men and women, there is nothing missing!"

Diana was tormented crazy by this broken cave, and she couldn't help but sigh at this moment.

"Look at your little bit of interest, I don't want to bring you back, I'm going to lead you to the interior of the island, trust me, Amen!" But the heart is a stinky fart.

"Don't sell it, tell me what to do!" Yun Yanuan asked anxiously.

The torches don't last long, and he must find the exit as soon as possible, otherwise it will be too dangerous for a few people to get around in the dark, especially the possible man-eating ants.

"Let's go back to the first marker!" With a wave of his hand, the team turned around and walked towards the long slope.

After a while, I came to the place where the first mark was made, but my heart muttered: "The first mark is about five hundred steps away from our entrance, and there are some errors, because my steps are uneven, but it is not much worse!" Come, come with me, and turn around again! ”

Yun Yanuan didn't know what medicine was sold in her gourd, but at this moment, only this girl had a so-called way, so she could only listen to her, and walked back five hundred steps like a fool.

"Are we wasting our time?" Ami Se was a little puzzled, even a little unhappy, because walking back and forth like this is like a child's game.

Yun Yanuan didn't like her attitude, she didn't have the consciousness of a newcomer at all, especially the girl didn't consider her ethnic position, so she didn't give a good face and said, "Why don't you wait for us here?" ”

Seami saw the displeasure of this only man, hurriedly put away her tsundere, restored her delicate and weak face, shook her head and said that she was scared and wanted to go along, and apologized very sincerely.

Her expression changed so quickly, which made Yun Yanuan very uncomfortable, and she had the feeling of seeing a two-faced person, but she didn't think much about it.

After walking back in five hundred steps, Ke Xin asked the four people except himself to stand facing the rock wall, one meter apart from each other, and then gave the order: "One. Two. Three. Bang ...... wall"
