The water-cold raindrops fell on the two of them, dripping down the corners of their faces and clothes, and the pitch-black lightning guns, splashing one after another, and the surrounding time seemed to be about to freeze.

There was a hint of surprise in the veiled woman's eyes, but it soon disappeared, she gently stretched out her left hand, lifted the veil, and revealed an old face that Chu Yunsheng didn't expect at all, where is there a fox spirit who should have a peerless face? The dry skin, wrinkled, as if stacked on top of each other, the whole person is more like an old lady who is about to die.

"Surprised? This is the price of using forbidden arts. She didn't seem to be in the slightest panic at the tip of the gun to her throat, and said softly.

Chu Yunsheng was indeed a little surprised, this was different from all the versions he had heard about this woman, but it was just surprise, the essence of the matter had not changed.

He shook the body of the gun and said coldly, "Who are you?" ”

The veiled woman smiled back, looked at Chu Yunsheng, and said, "Since you can understand what I'm singing, does it matter who I am?" In fact, what you want to ask is not who I am, but who are you? Right?"

Chu Yunsheng's heart was shocked, and he said angrily: "Nonsense! Tell me who you are? Otherwise, you won't survive for ten seconds! ”

Unexpectedly, instead of being afraid, the veiled woman pressed her throat against a point and sneered: "Really? Is it very capable of killing one of your own kindred? ”

Without hesitation, Chu Yunsheng stabbed the tip of the spear slightly into her skin, breaking out a trace of blood, and said coldly: "Ghosts are your kindred!" If you don't say anything else, die! ”

The veiled woman suddenly took a step back, left the tip of the gun, and said with a frown: "So you don't know anything yet?" But how can you understand it? Is it one"

She didn't continue, but kept looking at Chu Yunsheng, as if she didn't want to say anything more.

Chu Yunsheng's face was cold, he had never been a person who liked to kill indiscriminately, but he really had a heartfelt slow evil towards foreign races, and he was about to stab him with a gun.

"Why don't I tell you how darkness comes!" The veiled woman remained motionless, her eyes flashing, and she suddenly spoke.

The lightning bolt came to an abrupt halt.

"Say!" Chu Yunsheng retracted his body, and the rain gathered along the body of the gun to form a line behind his back, dripping into the ground.

Regarding how darkness came, the predecessors of the ancient book had a narrative explanation, where the predecessors called it "the heavenly track closed", but not to mention that Chu Yunsheng understood the rules and graphics he listed, it was these explanations, and it was only a narrative predecessor who did not seem to want to waste limited space on this kind of thing.

As far as Chu Yunsheng's current heart is concerned, how did the darkness happen? Why is the end coming? Since the darkness, so far, many, many bizarre things have followed, so that he gradually understood some truths: since the heavenly track is sealed, there must be a "person" who seals it, and there must be a "reason" for sealing it, especially the "passing" of the ship mound below, and Yan Min's hatred for thousands of years, which makes him feel that a huge historical figure is hidden in the endless river of years.

But these things have nothing to do with the predecessors of the ancient books, according to the records of the ancient books, when the predecessors came to the earth, his form was extremely urgent, and he died soon, and there was not enough time to find out who sealed the heavenly rail, and he didn't seem to have any interest in verifying the heavenly rail, not to mention the heavenly rail, even those overlords, super civilizations, could not fall behind in his eyes

West, just a brush.

He was only shocked by the stele, and even had a wonderful "exchange" with the stele that Chu Yunsheng had also experienced, the difference was that Chu Yunsheng saw the trajectory of his ancestors, while the predecessors "saw" a "legend" that was so far away that it had been swept into the garbage heap and could only be found on the worship murals on some remote and very ancient death stars.

When the predecessor first started to write the ancient book, the purpose was only because the humans of the local primitive tribe took care of his last time, but in fact, what he revealed between the lines was that he didn't want to interfere with the earth's heavenly orbit being sealed and so on, but after discovering the stele, he immediately raised the height of the book to the point where he hoped that the successor would attach great importance to this legend and find his own people for him, and then find the stele to beware of the evil demons outside the sky.

And Chu Yunsheng, as the inheritor of the ancient books of his predecessors, has also been following the ideas of his predecessors, thinking that his system has nothing to do with the Heavenly Rail Seal, and his predecessors can be said to be completely outsiders, and he is only the successor of this outsider, belonging to people who should not have appeared in the first place, and has nothing to do with this huge historical figure. ,

But the predecessors don't know if they didn't take it into account, or if they were deliberately negligent, he is an outsider, and his successor to the ancient book, that is, the current Chu Yunsheng, is not an outsider! He is a human born and raised on Earth.

So when Chu Yunsheng heard the sad songs and words of the Seven Insects in the ship mound that only he could hear, he was actually very flustered, because he had always felt that those huge historical figures had nothing to do with him, and he was just a marginal person holding the relics of an outsider.

What scared him even more was that he was afraid that he would be proven to be an alien race, as the Divine Domain said, a foreign race with a fragment of the life base of other races in his body,

Just like children will worry about whether they were born by their parents, Chu Yunsheng cares very much about being a "human", not any other monster, and he was born by his parents! Even when he was a bug, he always wanted to restore his body.

Therefore, the sad song of the veiled woman greatly stimulated Chu Yunsheng's sensitive area, the difference was that he wanted to take the initiative more now, either he forced her to say something and completely figure out what was going on, or if she refused to say it, he would kill her immediately to prevent future troubles, in his consciousness, all foreign races were not a good thing!

In fact, he prefers to believe that the reason why he can hear those things, but he doesn't know anything as the veiled woman said, is because he cultivated the system of the ancient books of his predecessors, and not because there are any remnants of the base source fragment in his body, at least there has never been any more strange things in his head, and everything is still his original, although there is nothing too luminous in his life, but it is his own memory and life, and for him, this is one of the most precious things,

Chu Yunsheng absolutely can't tolerate being robbed of himself like the Heavenly Guide of the Divine Domain, or having an extra memory of life that doesn't belong to him, he is him, between heaven and earth, unique, irreplaceable, and not allowed to add anything more!

"You don't need to be so nervous" Seeing that Chu Yunsheng's face was always tense, the veiled woman said lightly: "Even if you can hear "Mourning", you can't remember anything, and you are just an ordinary combatant at best,"

"Mourning?" Chu Yunsheng thought of the sad song full of sadness and remorse that even made him cry involuntarily, and said with a slight squirming mouth

"Yes, it's called Mourning, Mourning!" The veiled woman nodded, her face darkened, and after a moment, she suddenly said, "Have you heard of the Mebius circle?" ””

Chu Yunsheng shook his head, not knowing what she was talking about,

The veil woman smiled, folded the veil she took off into a long band in the rain, and then rotated one section 180 degrees, and then glued it together with another section, showing it in front of Chu Yunsheng, and said: "This is a Mebius circle, it has only one side, no matter where you start from there and finally return to the starting point, the route you have traveled is one face, and it is completely closed."

"What do you want to say?" Chu Yunsheng shook his head incomprehensibly, not knowing what she was doing,

The Veiled Woman ignored him and continued, "You can use your imagination to understand this plane as a vast two-dimensional space, and you will find that I have just turned it around a little bit and closed it off,"

Chu Yunsheng still didn't understand what she was talking about, but this time he didn't speak, just looked at her fixedly, to see what she wanted to say.

"The Mebius circle is a geometric problem discovered by humans in the 19th century, and the reason why we borrow it is because it makes it easier for you to understand what is happening later, although the metaphor is too simplistic and even naïve, but it is the only way to make you understand.

The veiled woman let go of the long belt and curled up a tube again, twisting and turning as if to explain.

Chu Yunsheng knew that the implication of her words was that her IQ was not enough, and she could only understand the superficial truth, but he didn't care, he never felt how smart he was.

The veiled woman glanced up at Chu Yunsheng, seemed to be very satisfied with Chu Yunsheng's "modest" attitude, and continued: "If time is regarded as an axis, not a dimension, and it is independent, let's not care whether this axis will be shortened or lengthened due to the movement of space, we will only discuss the problem of space in a small way, as you just saw, in three-dimensional space, we can use an extra dimension, similar to the method and technique of forming a Mebius circle, but in fact it is ten thousand times more complicated, Form a two-dimensional space and completely close it, there is no exit, and you will never find a three-dimensional world"

Chu Yunsheng was not too stupid, and quickly found a contradiction, and said: "But what you are closed is a circle, not a flat plane."

The veiled woman continued to play with her slightly more complex model without raising her head, and said: "Yes, but that's just because you are now standing in the perspective of three-dimensional space, in fact, if you are a creature living in this closed two-dimensional space, you will never know that this is a circle, you will only feel that this is a plane, the world you live in,

However, it is precisely because it exists in a three-dimensional space, in fact, it is indeed a closed circle, so the creatures living in this closed two-dimensional space, after fully exploring and understanding their world, some intelligent creatures will give birth to ideas that they cannot imagine or understand, and they will feel that there should be at least one dimension to support and ensure the existence of their two-dimensional world.

This dimension is the third dimension, but they have never seen the third dimension, and they will never know what the third dimension looks like, so they can only guess and imagine,"
