"Of course it's true."

Jiang Xinghuo faced the bearded man's question and said affirmatively: "It doesn't matter, if you think about the example I will talk about next, you will definitely be able to understand why I said, 'Productive forces determine production relations, and the economic base determines the superstructure'." ”

"Please tell me more about Mr. Jiang." Zhu Gaoxu also listened to it with relish and wanted to continue listening.

"Let's talk about the timeline, just now we said that from the beginning of the Zhou Dynasty, the form of the dynasty began to gradually change from a slave dynasty to a feudal dynasty, and the inevitable result of feudalism is the annexation war of feudal lords."

"With the spread of iron farming tools and ox ploughing, well, that is, the progress of productivity again, the land that could produce a great deal of wealth began to become the core interest of the princes."

"The more land a prince has, the more people he can support, the more troops and the tax base he gets, and then gain a greater advantage in feudal annexation wars. Marked by the victory of the king of Chu, the transformation of the feudal dynasty into a unified dynasty has in fact been irreversibly carried out. ”

"It is precisely because of the progress of the productive forces that the well field system began to collapse, and after the Shang Dynasty changed the law, 'the whole world is not the king's land' was denied in the legal sense, and the tax per mu made the land officially become private property at the legal level, and the Qin State fully transferred to the 'farming war' system, and the productive forces once again determined the relations of production."

"At the same time, the economic foundation also began to determine the superstructure, after the Qin State unified the world, abolished the feudal division, set up counties and counties, and established a central centralized system with the prime minister and the three princes and nine secretaries system as the core."

"So that's it...... Do you understand? ”

Zhu Gaoxu suddenly realized.

"Because iron plough and ox ploughing replaced cooperative tillage, the productivity improved, so the relations of production changed, and the slaves who farmed for the Son of Heaven and the princes became peasants of higher status, and this time even had the right to produce grain and distribute it!"

"And there is more grain produced, and Daqin, which is based on the farmers' cultivation war, will abolish the feudal feudal counties and counties, because the peasants do not belong to the feudal princes!"

In the secret room, there was complete silence.

Zhu Di was stunned for a moment before he asked.

"Master, you said that a stupid boy like the second child can use these two principles to deduce the fundamental reason for the reform system of Great Qin after learning it, isn't this a dragon slaying technique?"

Dao Yan's expression changed from disbelief to self-doubt.

Dao Yan shook his head, but still said firmly: "Jiang Xinghuo is still talking about 'current situation', not 'luck'. ”

"Does it make a difference?" Zhu Di couldn't help asking.

"There is a difference, the 'current situation' is something that mortals can grasp, and the 'luck' is something that true celestials can perceive."

This is a very mysterious statement.

However, Zhu Di has already believed most of it.

This is not surprising, because Jiang Xinghuo's insight is too far-reaching, and what he said is so reasonable, it is difficult not to believe it.

Jiang Xinghuo's so-called "Theory of National Fortune" is obviously inconsistent with Zhu Di's familiar history, but it directly points to the essential truth after the fog of history, so interlocking, and even makes Zhu Di feel that Jiang Xinghuo is really an immortal who stands on the long river of time and overlooks thousands of years of history!

"After all, the old man doesn't believe that there are really immortals in this world."

"And...... If the latter speculation comes true, does Your Majesty think that these words were heard by us on our own initiative? ”

Zhu Di's expression also became solemn.

Zhu Di has read those folk scripts, immortals can't take the initiative to reveal the heavenly secrets to mortals, otherwise they will suffer from heaven's curse.

If Jiang Xinghuo is really an immortal, then in other words, does the other party know that he and Dao Yan are eavesdropping next door, so he deliberately told the dragon slaying technique?

"Hiss~"

Zhu Di and Dao Yan glanced at each other, obviously the two thought of going together.

Jiang Xinghuo, who was on the other side of the wall, of course didn't know that Zhu Di and Dao Yan had already started to make up for their crazy brains.

However, it is indeed not an exaggeration to say that Mr. Ma's two principles in the world are dragon slaying techniques.

And today's bearded man seemed to be exceptionally smart, and he even asked another question.

"Mr. Jiang, I believe it, but I suddenly have a question."

"Say." Jiang Xinghuo encouraged students to actively ask questions.

Zhu Gaoxu asked in a deep voice: "Then according to what you said, 'the productive forces determine the relations of production, and the economic base determines the superstructure', if one day agricultural technology advances again, is it time to change the dynasty, and the Ming Dynasty will die?" ”

Hearing this, Zhu Di also pondered.

Zhu Di thought about it according to Zhu Gaoxu's train of thought, and he also felt that it was very likely.

Slash-and-burn farming became cooperative farming, which led to the demise of the slave Shang Dynasty and the establishment of the Zhou Dynasty's feudal system, patriarchal system, and well-field system.

Cooperative farming became iron plough and ox farming, which led to the demise of the feudal Zhou Dynasty and the establishment of the county system, the central centralized system, and the private ownership of land in the Qin Dynasty.

Once the Ming Dynasty's agricultural technology made breakthrough progress, would it be a good thing or a bad thing for the Ming Emperor?

After all, if the grain output per unit of farmland is more, the Ming Dynasty can get more tax base and population for a period of time, but the total amount of farmland is capped.

Just like Jiang Xinghuo said, whether it was the Xia who turned from the tribe to the dynasty, or the Zhou who turned from slavery to feudalism, or the Qin from feudalism to great unification, it was all due to the increase in grain production and population explosion due to the progress of agricultural technology, which led to the change of the dynastic system.

"What you're thinking about makes perfect sense."

Jiang Xinghuo paused for a moment and said helplessly: "But have you ever considered that according to the lifespan of the Ming Dynasty, it may not last the next agricultural technology progress?" ”

What?!

Hearing this, Zhu Gaoxu was stunned.

"Mr. Jiang." He opened his mouth with difficulty, "Are you saying that the Ming Dynasty will die before the next agricultural technological progress, so you don't have to think about the fact that agricultural technological progress will lead to the destruction of the country at all?" ”

Zhu Di, who had a hint of joy on his eyebrows just now because of his second son's enlightenment, instantly became gloomy.

Jiang Xinghuo, even said that Daming would not survive the next agricultural technological progress and would die in the country?

Saying it in front of him, the emperor, isn't this cursing him to his face?

Zhu Di looked back at the secret room where only he and Dao Yan were the two, waved his sleeves unhappily, and continued to listen.

"That's true."

Jiang Xinghuo pondered the wording and said, "Originally, this was the content of the second lesson, but since you have asked everything, then I will continue to tell you, do you remember the two questions I asked you before talking about "The Theory of National Fortune"?" ”

"I remember."

Zhu Gaoxu repeated it.

"Why is it that at the beginning of the dynasty, the king is always wise, and after two or three generations of emperors, he can often reach the peak of national power, and then several generations of kings are incompetent, and finally the power is in the hands of the eunuchs and harem ministers until the country dies?"

"Why is there a phenomenon of 'the world must be divided for a long time, and the world must be united for a long time' repeated over and over again on the land of China? Why did the life span of dynasties generally not exceed 300 years? The change of dynasties from generation to generation, is it really a cycle of five virtues and heavenly ways? ”

"Then I'll tell you the answer right now."

"This is the second lesson of the "Theory of National Fortune" - what is dynastic longevity."

Zhu Di and Dao Yan glanced at each other and sat up straight.

If what Dao Yan said is true, Jiang Xinghuo can really say it accurately about 'luck', then Jiang Xinghuo's identity as an immortal, I'm afraid the probability of being an immortal will be greatly increased!
