Chen Xi looked at Cai Yan curiously, to be honest, he was a little unsure of Cai Yan's depth now, Cai Yan understood the knowledge imparted by Chen Xi very well, and after understanding it, he also gave birth to his own thinking.

"It's good to hear it, you are indeed a little aggrieved that you didn't take the exam." Chen Xi said.

"It may be that I instilled some of my own thoughts into Wang Yi, and now she doesn't write profoundly, but in general, she has written what I said at the beginning." Cai Yan said, saying that here Cai Yan looked at Wang Yi again, she is really a very smart woman.

"I may have thought about these things very little before, but under the rule of Xuande Gong, I have a lot of time and have come into contact with a lot of absurd but thoughtful classics." Cai Yan slowly tells her own story.

"It may be that I was born with the ability to understand and understand the classics, and those books of yours have given me a lot of food for thought, many of my concepts have changed, and the perspective of seeing things is much different than before." Cai Yan obviously showed a sighing look.

"I was worried about it, but so far, it should be good, and many things seem to me to be very simple now." Cai Yan looked at Chen Xi faintly, and there was no confusion in his eyes.

"In my opinion, dynastic change is just an inevitable process, which can make him come late or early, but it can't be changed, which is the inevitable result of selfish desires and interests." Speaking of this, Cai Yan smiled, "It must have been taught to me by you." ”

"The real collapse of the dynasty is essentially because there is no promotion channel at the lower levels. The upper echelons have a monopoly on all interests, and in this case. Vested interests also want to get more benefits because of their selfish desires. Cai Yan retold it with the kind of words that Chen Xi had used, and I don't know why Cai Yan used these words. Chen Xi was slightly upset.

"As for how to crack it, the most fundamental thing is to improve output, whether it is agriculture or the handicraft industry that Chen Hou said, as long as it can solve the problem of clothing, food, housing and transportation, the dynasty will not collapse no matter how turbulent." Cai Yan was slightly disappointed when he said this, "But it's impossible." ”

"Why can't it?" Chen Xi sighed in his heart, Cai Yan's comprehension is really amazing, if this kind of person is in the future generations. I'm afraid it's a person who learns God,

"Land, acres, I have calculated that the population of 60 million is probably the warning line that Chen Hou said, and once the dynasty is unified and enters the stage of prosperity, the population of the world will skyrocket, I specially checked the population from the first Han Dynasty to the Ling Emperor......" Cai Yan was obviously a little sad, she had never paid attention to these things.

"Hmm. Indeed it is. Chen Xi nodded and said, "The population of 60 million is indeed the limit of the current bearing capacity of the Central Plains, so I want to expand the territory." Because of Physician Hua and Physician Zhang, the plague did not break out, and because of the suppression of Xuande Gong, the Central Plains did not enter the level where the princes regarded the people as mustard. Now the Central Plains has a population of nearly 50 million......"

Cai Yan had already guessed this number, and because of the lot of knowledge inherited by Chen Xi, she already had a clear understanding of the war.

It can be said that a large number of people disappeared during the war. It is the foundation of the next prosperity, because so many people have died. Only then did we have land, and only then did we have acres of land.

Unfortunately, the biggest problem did not change, and in the process, the number of the family became larger, and the population tolerance limit of the Central Plains land fell again with the same grain yield per mu, until more violent unrest broke out and the family took out part of the land.

"So you should expand the territory, your thinking is indeed right, the solution is that I chose to improve agriculture and handicrafts as much as possible internally, and put the surplus manpower into expanding the territory externally, instead of clearing the population in the civil war and encroaching on the land of the brothers, it is better to fight out and take other people's land!" Chen Xi said coldly.

If it was three years ago, Cai Yan might have felt that Chen Xi had no gentlemanly style in doing this, and he might even think that Chen Xi had done too much, but after three years of understanding, Cai Yan also understood how his current life came about.

"Later, if I want to read the papers, I will also participate, just to see if there are any amazing words." Cai Yan changed his words and proposed to Chen Xi.

"It's fine." Chen Xi did not refuse in this regard, to be honest, these people in this exam answered quite well, but it is a pity that Chen Xi's vision is too high, and he always looks at the problem from a historical perspective, so it seems that this group of people behaves averagely.

"......Huh" Lu Yu exhaled deeply, and he didn't know if it was because he was hit by Mi Zhen's behavior or what, Lu Yu, who was holding his breath, was very smooth when answering the last question, almost without adding points.

[There shouldn't be any problem in this way, Lu Boyan, that bastard, shouldn't be able to pass the test. Lu Yu thought in his heart, [I don't know how that guy is now. 】

Just when Lu Yu was about to turn his head to look at Lu Xun not far away, he suddenly found Xun Yue standing behind him, and immediately sat down.

"Very interesting answer." Xun Yue said to Lu Yu with satisfaction, and then walked towards the other place, he had been standing behind Lu Yu for a long time.

Lu Yu also started from the degree of food and clothing, explaining the problems in the last years of the dynasty in addition to the political environment, but Lu Xun took the road of conquest and expanded his acres as much as possible, while Lu Yu embarked on another path based on the current environment.

Under the condition that the current environment remains unchanged, in fact, the most important thing to do is not to expand, the limit of its own ruling scope has been determined, then the most important thing to do is to improve the utilization rate, not only the acres of land, but also the utilization rate of people and things.

Lu Yu also gave examples of the comparison between the grain yield per mu in the past and the current crop, as well as the changes between the grain production area in the past and the current grain production area, and then proposed the relocation of densely populated areas, as well as the official reclamation, to maximize the use of the resources that are currently available.

Overall, this answer is very good, but Lu Yu also said in the end that there is no way to solve the fundamental problem, but he still chooses to explore his own limits, after all, he feels that the land under his feet is not infinite.

Although this is already off-topic, the person who gets the paper cannot deny this fact, and Lu Yu also pointed out the distance of the empire's limit in the volume.

It's just that unlike others' goal of extending the life of the empire indefinitely, Lu Yu said bluntly that he can't do it at all, after the limit of the empire's rule appears, he should not continue to consume national strength to expand his territory, but should turn to exploring his own limits, digging in all directions, and paying equal attention to technology and acres! (To be continued.) )
