The old man Ye Su didn't answer the question, but the answer was already obvious, obviously the 1,386 stone steps outside the temple were the handwriting of this old man, and even Yang Chen suspected that the entire temple was built by the old man in front of him.

And in the past ten years, in addition to replacing the stone bricks on the stone steps, he has spent more time thinking about one thing.

Why did the old man Ye Su embarrass him in the first place.

It is true that they once met the old man Ye Su on the grassland, and they also had a few conversations, sometimes because they disagreed, the words were quite fierce, and even Yu had threatened to kill the old man Ye Su several times.

But at that time, it seemed that the old man Ye Su was not the kind of villain who held grudges, and later from the stories of the little girl Zhuoma "There was a mountain once upon a time", Yang Chen became more and more sure that the old man Ye Su was definitely not because of Chu Yu's disrespect for him and held a grudge.

So why, when he was about to finish repairing those stone steps, Old Man Ye Su happened to take his three disciples to climb the mountain?

Mountaineering is mountaineering, why destroy those stone steps?

And why did they decide to go down the mountain when they were about to finish it again?

After countless days and nights of thinking, Yang Chen realized that the old man Ye Su was actually helping himself.

He repaired three thousand and more than 1,000 steps of the avenue three times.

That's three thousand.

The first time, dusting.

The second time, the solid book.

The third time, Lixin.

This is what Old Man Ye Su wanted him to do.

Although it was not yet clear what the point of his doing this was at this time, Yang Chen knew that he had invisibly owed the other party a great favor.

It's just that he can't figure it out, the old man Ye Su has always believed in himself, although now he is no longer the king of angels, the god of the world, but in essence, he is still an angel.

So why did the old man Ye Su help himself?

So above, the first question after climbing the mountain, he asked this one.

However, the old man Ye Su did not answer the question, and answered the two questions as one question.

If you live long enough, in addition to seeing a lot, knowing a lot, and understanding a lot.

Human beings themselves should believe in themselves, but the problem is that the species of angels is real, no matter what the principle of their existence is, but it is still a kind of life.

Existence is truth.

This is what Old Man Ye Su wanted to express to Yang Chen.

Yang Chen understood, so he respected the old man in front of him more and more.

The Maple Blue Big 6 has been around for a long time, and the exhibition of human beings has also lasted for a long time, even longer than the human heritage on the earth.

But in fact, it is precisely because of the emergence of cultivators that it takes an extremely long time for each generation of dynasties to change.

The exhibition is naturally slow.

A more important reason is that there is only one large 6 in the maple blue big 6, although it is divided into countless large and small countries, but in general, all information exchange is unified.

The status of the temple on the Big 6 is also unified.

Then a problem arises, since the temple is supreme, it is natural that it cannot tolerate the existence of doctrines different from the temple.

So there will be no Galileo in this world, there will be no scientists like Newton, because once such a existence appears, it will be ruthlessly erased.

Old Man Ye Su had lived for a long time, so he had seen or said that he had been a part of those beings, so he was able to know many things that others did not know.

For example, the big 6 they live in is just a small piece of the planet, for example, this planet is round, just a corner of the universe.

Because of this, his thoughts were able to be comprehended by Yang Chen, and then admired.

He saluted respectfully to the old man Ye Su, sat down in front of him, and very unceremoniously lifted the teapot and poured himself a cup of tea, and then said: "There are three thousand avenues, thousands of universes, and thousands of forms of life. ”

Hearing this, Old Man Ye Su put down the teacup in his hand, glanced at Yang Chen in surprise, and then said, "But what we are still pursuing, it seems to have become common sense with you?"

"It's true. ”

Yang Chentian shamelessly turned the research results of the previous generation of sages into his own, and said eloquently: "The universe is endless, and in this endlessness, there can be only one kind of life in nature. ”

"Wonderful words. ”

Old Man Ye Su laughed, completely caught in a state of communication, and asked, "According to what Mr. said, the universe is endless, so there is no boundary?"

"Otherwise, the universe has boundaries. ”

"If there are boundaries, how can there be no end?"

Yang Chen didn't know what the scientist named Instein thought back then, but at least he knew the assumption that the ants crawled on the basketball, and replied at the moment: "If the universe is a sphere, then no matter where it comes from, it can eventually return to the original point, isn't there a boundary?"

"The problem is that, in this case, it's not that the universe has boundaries, it's that the universe is finite. The old man Ye Su retorted with a blow of his beard and a glare.

Yang Chen didn't know that his own understanding of the scientist was wrong, and the old man Ye Su gave the correct answer, but in his cognition, the universe should indeed be infinite, but it should have a boundary, but since there is a boundary, how can it be infinite?

So in the conversation with the old man Ye Su, he became more and more vague, and had to say: "That's just a hypothesis, but if that's the case, then should the ant crawl outside the sphere or inside? If it crawls inside, then what is the scenery outside the inside? If it crawls outside, is the ant outside the universe or inside the universe?"

Caught in the madness of discussion, Old Man Ye Su didn't notice that Yang Chen had divided the universe into two parts, inside and outside, and naturally didn't know that Yang Chen's problem in doing so had actually planned the universe as a category with boundaries, after all, between inside and outside, there was a boundary.

He still shouted unconvincedly: "There is something wrong with your idea, whether it is outside the ball or inside the ball, ants can't fly out of the universe, right?"

Whether it was the destruction of a universe that he had encountered before, or whether he was now in a closed universe, Yang Chen didn't know if these belonged to the universe, in his opinion, these things he encountered were all born within his own universe, especially the thirty-six human worlds under the order of angelic civilization, which made him firm in this belief, so he became more and more confident in this conversation.

I only heard him say: "What you said is indeed true, but the question is that if the universe has no boundary, but is finite, then what is infinite?"

The old man Ye Su was choked by his words, and the hot tea he had just drunk in his mouth was squirted out by him before it passed through his throat.

He pointed at Yang Chen, his fingers trembled violently, and he shouted angrily: "You are using strong words. ”

"The old man is old, don't be so angry, don't accidentally catch your breath, I can't afford it. Yang Chen spread his hands and said, in this kind of academic truthfulness, he completely forgot his respect for the old man.

The old man Ye Su became more and more angry, and then suddenly thought that he seemed to be caught in the discussion of the universe, and completely forgot the original intention of letting Yang Chen go up the mountain, and couldn't help but wonder, what did the old man do when he was looking for this kid to go up the mountain?

Because of this thought, he completely forgot about Yang Chen's disrespect for him, and began to bow his head and think.

Seeing the sudden appearance of the old man Ye Su, Yang Chen felt a little embarrassed, what he said before was completely the result of the research of the previous generation of sages, and as for the last sentence, it was completely strong.

The reason why infinity is infinite is that it is not finite.

But the problem is that all things that can be known are limited, and the unknowable and incomprehensible things only exist in people's minds, but there are also places that cannot be thought of, and there are also limitations.

So what is infinity?

This is a question that has no answer, and the old man Ye Su naturally doesn't know.

But who knew that just when Yang Chen was thinking like this, the old man Ye Su suddenly spoke: "Time is infinite. ”

When he opened his mouth, his voice was very loud, startling Yang Chen, and then he realized that he didn't have anything to refute the other party's conclusion.

Time is real and can be known, at least partly by man, and no one knows where it came from and where it will end, the unknown is infinite.

Yang Chen has nothing to refute this.

Because he doesn't know.

His ignorance is also limitless.

For a while, because of Old Man Ye Su's words, Yang Chen suddenly became silent, so Old Man Ye Su became extremely happy, but when he thought of his original intention of looking for this kid to go up the mountain, his old face turned red, and he said embarrassedly: "Ahem...... It's really a meaningless conversation, so what if we know that? So let's talk about something more realistic, right?"

Yang Chen glanced at the old man with disdain, since there is no point in his heart, what are you so proud of?

However, Yang Chen didn't know that in the near future, this conversation, which was defined as meaningless by Old Man Ye Su, would become extremely important, and it would also make him regret it.

It's just that these things were born in the future, and although Yang Chen was extremely unhappy at this time, he had to admit that his thinking really couldn't keep up with the logic of Old Man Ye Su, so this discussion about the universe provoked by him ended temporarily.

It's just that as an earthling with countless theories that are incomparably advanced, Yang Chen's heart is still a little unconvinced when he is said by an old man who is still in the feudal era at this time.

But then I thought that even if I added my previous life, I would only live for a few hundred years, but the old man in front of me had lived for thousands of years, and it was normal to say that he was normal, so I felt more comfortable.

Anyway, this conversation, which seems to be meaningless and meaningless at the moment, is finally over, just noticing the word "reality" behind the old man Ye Su, Yang Chen's heart still jumps, and he faintly feels that the old man Ye Su looks like a weasel giving a New Year's greeting to a chicken, so he has to be more careful.

So he asked cautiously: "I don't know if the old gentleman is coming down this time, what advice do you have?"

Yang Chen said polite words on his lips, but his hands were extremely unpolite, he drank all the tea and poured himself another cup, this tea is indeed okay.

If the three guests waiting outside the cottage knew what Yang Chen was thinking at this time, they would definitely rush into the house and scold him.

Even the three of them didn't have that mouth, but now they were treated like boiled water by Yang Chen and poured and drunk, if they knew, they didn't know how distressed they were.
