Immortality, but people in primitive society

"I don't like being the ruler, so I want to study the roundness of the earth and the squareness of the sky, but they won't allow it."

"I told them that the sky is round and the earth is square, but they didn't believe me. They even thought I was betraying the ancestors of the Buting Kingdom and wanted to kill me. I had no choice but to step up my career and become a great leader, and then capture the king..."

"The theory that the sky is round and the earth is square is something we at Wenxing have painstakingly concluded through the efforts of countless generations. We observed the stars, the changes in the heavens and the earth, and summarized various cultivation practices before arriving at the conclusion that 'the sky is round and the earth is square'..."

The great teacher talked incessantly, and daytime listened attentively beside him.

If it were in the past, he would have found some reasons to refute it, but now he just thinks that the theory of the earth being round is really amazing!

The sky is round and the earth is square, which not only describes the topographical structure of the world, but also represents a big picture view of the universe.

The early Wenxing tribe constantly drew maps, observed the stars, and then studied and practiced. Generation after generation, they finally summed up this theory.

The amazing thing is that this theory is based on the Taichu Bagua, so it is not really a cultivation path, but more like a philosophy. And this philosophy can be well fed back into cultivation.

Of course, the major sects do not have a very deep understanding of the yin and yang of heaven and earth, which may be related to the fact that they cannot surpass a certain level of strength.

From the perspective of the day, he thought of many more things through the roundness of the sky and the squareness of the earth. The yin and yang of heaven and earth, the laws of heaven and earth, the creation and destruction of the world, and so on...

After the Great Master finished speaking, Bai Tian remained silent. He just stared quietly at the hemisphere in front of him.

Dajiao didn't say anything either, just stood obediently by the side.

After a long while, Bai Tian finally reached out to fiddle with the hemisphere and said calmly, "Have you ever considered the possibility that the earth might also be a very big ball, and the sky is infinite?"

The Great Master frowned and asked, "In other words, the land we are on now is just a very small part of a very large sphere?"

Bai Tian sighed, "I don't know either. I just find it a little strange. If what you said about the earth being round is true, then who created this land? The surrounding sea must have an end. Where is it?"

"Also, the stars and the sun, where are they? Why does the sun rise and set?"

The great master stared at the hemisphere with a frown on his face. After a long pause, he mused, "Perhaps, it really is a sphere. Haotian, look at it this way. If the world we're in is truly a sphere, and the sky is also round, then wouldn't that make the sky round and the earth square?"

"It's just that the place we're in is just one of the eight trigrams of Taichu. The countless trigrams around it are either nothingness or water..."

The idea of ​​pupils shrinking during the day is very bold!

The Great Master continued, "Haotian, perhaps we can really give it a try. If we start from the east and sail along the sea, if we can really return to this land, it means that we really have a big ball under our feet."

"Perhaps there are many continents on the sphere, like the Taichu Bagua, with each hexagram representing a continent; or perhaps there is only this continent."

"But I beg to differ with your claim that the sky is endless. I've read records that say Zhuanxu and his companions... well, you and them, together, opened up a connection between heaven and earth, thus creating the spirit world. Since there's a spirit world, that sky can't be endless, otherwise where is it?"

Yes, if the sky is endless, how do we explain the relationship between the three realms?

Multidimensional space? Or dimension? Plane?

Ultimately, however, whether this concept of the earth being round and the sky being square is actually true still needs to be verified. Of course, the philosophical concept of the earth being round and the sky being square does align well with cultivation.

Thinking about it, Bai Tian whispered, "We still need to do more in-depth research. During this period of time, I will stay at your place temporarily. Please show me your research on Wenxing..."

So for the next period of time, I stayed in Buting during the day.

During the day, I returned to the spiritual world and shared the great religion's round sky and square earth with Su Ling.

Su Ling frowned as she listened. "If that's the case, then what about the spirit world? The spirit world initially overlapped with the human world, so it could be said to be a replica."

"If the space in the human world is boundless, then the spirit world must be the same. But water must have an end, right?"

"But if the human world is on a big sphere, then is the spirit world also on another big sphere? What about the heavenly realm?"

Bai Tian pondered, "Perhaps, the heavens are quite special. In the beginning, there was nothing in the heavens; everything needed to be created. Moreover, the heavens are still expanding; only the first level of heaven has appeared so far."

Su Ling frowned. "That's the problem. Since the heavenly realm is a flat space, the human world and the spirit world should be the same, right? Otherwise, how do we explain the heaven?"

Bai Tian pondered for a moment and said, "Su Ling, is there a possibility? According to the theory of creation and what Jiu Yin said before, the human world is very likely a flat space. And the so-called end, in fact, has no end, or is it that the end is the law?"

"You mean, when the surrounding water reaches a certain level, it gradually turns into a law and then folds back?" Su Ling touched her chin.

Bai Tian nodded: "Perhaps this is really possible. Under the control of the law, when the sea surface extends to a certain extent, illusions will appear..."

Bai Tian suddenly stopped talking midway through his words.

Su Ling couldn't help but wonder: "Why?"

Bai Tian frowned, "I seem to have thought of something, but I can't grasp it for a moment. Space stretches and laws fold..."

Suddenly, Bai Tian's heart trembled, "Su Ling, maybe we are wrong!"

"This place we are in is very likely a ball. But we are inside the ball!"

"The end of the sea is not the sea, but the sky. The sky and the sea are connected, but there is no clear boundary, because the end is the alternation of laws and is difficult to identify..."

"The human world and the spirit world are likely two concentric circles. It's just that because they are so vast and the land area is so small, they look like replicas."

"As for the heavenly realm, perhaps it is just breaking through the two concentric circles, transcending to the true outer space, to the true void space..."

As he spoke, Bai Tian's eyes lit up: "Su Ling, I understand! The laws of heaven that we need to comprehend are actually beyond the heavens."

"Perhaps we are just a speck of dust in infinite space, or perhaps a bead... Perhaps, perhaps there are many, many similar specks of dust outside the sky, endless..."

"No, no, how do you explain the sun? There has always been light in heaven, but we can't see the sun... Small hole, rotation? Yes, it's very likely. Suling, I want to go back to Buting Kingdom and do some experiments..."
