Chapter 568 (1/2)

Mo Xiaowan was really scared. Just now she felt that someone had been staring at her. Now she feels that way.

It was like an endless ladder. Xiao Chenyuan thought sister Sang's master could take them out of here by casting spells. However, it seems not. The cock has been taking them down the stairs. Unexpectedly, I don't know how long it took, the cock's head and neck fell down again.

Sang's master wanted to lead the way through the rooster. I'm afraid it's impossible.

Originally, Xiao Chen wanted to lead the way by burning runes, but he had to rely on the soul of a third party. However, the people who died here are afraid to be people tens of thousands of years ago.

How can they borrow their souls?

Xiao Chen doesn't know who built it?

When master sang saw that the chicken head was separated from the chicken neck, he could only put the body of the male chicken aside and take back the chopsticks.

Soon, Xiao Chen saw Sang's master take out the rune paper, burn it into water and let one of his disciples drink it.

Originally, the apprentice didn't want to drink when he was killed, but now he doesn't drink. Is it waiting for SANA to drink.

After the younger martial brother drank it, Xiao Chen felt that the other party's eyes became blurred. When Xiao Chen saw Sang's master, he didn't know what to whisper. When Sang's younger martial brother led the way, Xiao Chen didn't follow him.

Instead, he took sang and Mo Xiaowan back.

I don't know how long it took. To Xiao Chen's horror, he didn't even return to the fork this time.

Xiao Chen can confirm that the three of them have indeed walked out of the endless ladder.

”Xiao, Xiao Chen, where are we?” At this time, even Mo Xiaowan felt that the three didn't return to the original place at all, and it was always dark here.

There were many lights on the ladder just now, but there were none at all.

After the sauna took out the lighter and lit the light next to it, Xiao Chen looked ahead and still couldn't see the end. Looking down, he couldn't see the end either.

”I don't know where it is, but you take a break first. I have to think about countermeasures.” Xiao Chen said.

In fact, there are really endless stairs in the world, but it is not the so-called ghost beating the wall. It can also be explained clearly according to scientific theory.

This is the Penrose ladder. It is a famous geometric paradox. It refers to a ladder that always goes up or down but can't reach the end. It can be regarded as a variant of the Penrose triangle. The highest point or the lowest point can never be found on this ladder.

Penrose ladder was proposed by British mathematician Roger Penrose and his father geneticist Leonid Penrose in 1958.

Normally, Penrose ladder cannot exist in three-dimensional space, but it can be easily realized as long as it is placed in a higher-order space. Like Mobius ring and Klein bottle.

Xiao Chen is not aware of the endless ladder theory put forward by this foreign scientist. However, he did not expect that such a ladder could be built with the wisdom of the ancestors of the Chinese nation tens of thousands of years ago, which makes Xiao Chen really admire it.

He felt that if those tomb robbers outside really broke into here, even if they brought enough food for several months, they would finally die in such a place.

However, for thousands of years, no one should be able to get in, that is, when the sauna got the two jade pendants, he brought him in.

”Xiao Chen, what should I do now?” Sang asked.

In fact, she knows that her school organization has always studied the cemetery in Jiuli Valley, and even the earliest data map here is about the construction of this cemetery.

However, sang didn't expect that when she went inside, she found that it was completely different from her imagination.
