The 24 solar terms are the product of the countless revisions of the calendar in the agricultural era, and their determination principle is naturally not a big secret when later generations have already figured it out.

But in ancient society, especially in ancient times, this is completely a result of nothing, and Zhuhai has naturally never seen such a detailed calendar that can divide the twelve seasons into twenty-four.

This made Zhuhai fall into a deep shock, and on the other side, Akamatsuko was also reflecting on himself.

I killed this guy in one twenty-four solar terms, why didn't I think of pretending to be forced like this!

It seems that it was still bypassed by the other party before.

"However, the solar terms are not used in all places, if you go all the way west, wading through quicksands, as far as Bactria and in the land of the west, the 24 solar terms are no longer applicable, but those places also have their own set of calendars. ”

Zhuhai agreed: "I have been to a far place, in the West Pole of the former Republic of China, they have their own set of calendars, which is very different from the Central Plains, and even more different from the Oriental Sea. ”

Yu Zai nodded: "So, this is the difference between water and soil, in fact, it can also be regarded as the difference between heaven and earth, this heavenly character, is the climate, this earth character, is the terrain, mountains, lakes, soil, vegetation, birds and animals, tribal customs, are very different." ”

"If you ask me about the landform of mountains and rivers and the management of water veins, I can tell you now. ”

Yu Zai said to Zhuhai: "The terrain is called latitude in the east-west direction, and the meridian in the north-south direction, the mountains are high and heavy, and the water does not flow; the high and sunny places promote the growth of all things, and the low and dark places accelerate the decline of life; the hills are high, the peaks are majestic, and the valleys are low-lying. ”

“..... The damp heat and miasma make a man hoarse, the evil tendencies deaf, the forest makes a man's legs lame, the woods make a man's back hunched, and the riverbank makes his feet swollen........"

These are the original words in the terrain training, and Yu Zai is very familiar with this back.

has been following Chi Songzi for so long, of course, Yu Zai can also hold back a sentence or two, and this tone and wording are in line with the chattering communication of wizards in this era.

"The psychological and physical characteristics and dispositions of the tribal and the people who live in various places are similar to and echo the topographical and climatic characteristics of the terrain in which they live. ”

"But how did these terrains come to be?"

Yu Zai pulled out his axe, held it flat and released it, and the axe fell to the ground with a thud.

"Why does the axe fall towards the earth and not into the sky?"

"Why is it that the golden stone is produced in the earth and not in the sky?"

"Why don't rivers dry up after tens of thousands of years?"

Without thinking, "Because the earth has great power, which can bind all things, and wrath, it can overthrow all things." ”

He felt as if he had touched a bit of the real principle of the earth, and Yu Zai said: "I think that real geography should see the essence of all natural phenomena, just like rivers flowing for thousands of years without drying up, because between heaven and earth, there is a set of laws of circulating hydropower. ”

"But the birth of the great flood was because this law was broken, and the heavy rain was abnormal, constantly flooding the rivers, the earth rejuvenated, the ice and snow melted into huge waters, and the atmosphere flowed in the sea, and the hot and cold winds met to produce storms, rolling up a tsunami that shook the earth....."

Jihai was excited, so he told the Mingyi group about observing the moon and tides, and after listening to it, Yu Zai was really surprised.

In this era, there are actually island tribes living in the sea who have begun to observe the relationship between the tide and the sun and the moon?!

"This power between heaven and earth cannot be seen or touched, but it really exists. ”

"So, here's the problem, is the reason why you dare to divert the river is because you have found this law?"

Yu Zai said modestly: "The principle of the earth cannot be explored from a piece of land, you go from the plain to the hills, the hills have their own set of cycles, from the hills to the swamps, the animals of the hills cannot survive in the swamps, you go from the swamps to the desert, you will see that the animals there are hiding during the day and haunting at night." ”

"Divert the water from the east to the desert of the west, and the desert will keep swallowing up the water, so where does the water go?"

"In the cycle of heaven and earth, I tell you, the world can be divided according to this, and many of the states in which heaven and earth interact with each other are formed by climatic zones..."

Zhuhai is asking, Yu Zai is answering, and no matter what kind of question, Yu Zai can give an answer, and even a set of strict logic, Zhuhai gradually became distracted, until finally, he sighed: "The principle of such a vast world, I never thought that I would hear it in such a small land, no wonder the people here have no worries about food and clothing, spread songs and ballads, and can properly use the principles of heaven and earth, this is the sage who benefits the world!"

Yu Zai was taken aback, the name of the sage is not easy to take, but Zhu Hai is like a student who has learned a lot of knowledge, respectfully saluted Yu Zai, and said "Dazai" and retreated!

"I will leave, live up to the teachings of Dazai, look at the nature of the mountains and rivers in the world, the rivers, seas and lakes, learn astronomy and geography, educate the people, make them know the sky and recognize the location, and then write bamboo slips, and spread the name of Dazai!"

At this time, he was in high spirits, and was about to leave immediately, to go away and observe many changes in the heavens and the earth, he asked Yu Zai that this unwritten bamboo slip would be completely different from the humanities he had described in the past, but Yu Zai stopped him.

"Human geography is also a very important part of geography!"

Yu Zai thought for a while, and suddenly said: "I think you can combine the two, the phenomenon of humanity will also touch the essence of the principle of heaven and earth, you see, it seems that we qi refiners have been doing this!"

After saying this, several Qi Refiners nodded one after another, and said one after another:

"That's right, it's right, that's why we've been practicing!"

"Yes, after hundreds of years of cultivation, the essence of the principle of heaven and earth, we have been on the way to explore!"

"Oh, there's a lot we don't know!"

Zhuhai was immediately moved by the spirit of exploration and knowledge of several Qi Refiners, and hurriedly saluted:

"You are all the pioneers of the principle of heaven and earth, the guide of benefiting all living beings in the world, so that they can enjoy food and clothing, and open up the well-being of all people.

The Qi Refiners were immediately very satisfied! They waved their hands again and again, saying that "it is just a matter of duty"!

Look, isn't this forced to be put back!

Mother's, it's really comfortable to have an apprentice!

Zhuhai said that he asked Yu Zai to give a name to this Jian Mu that had never been written, his expression was sincere and serious, Yu Zai thought for a while, and suddenly had a somewhat funny mentality, and said to Zhu Hai and all the Qi refiners: "The so-called human law earth, earth law heaven, heaven law Tao, Tao law nature.... So...."

"This is called 'man and nature'...... Right....?"

Yes, man and nature!
