Another twenty years, when Ling Chen saw Balu again, the other party was already an old man, his temples were gray, it was difficult to move, and his eyes were clouded by the years, but he was a little more determined.

Ling Chen didn't have the heart to communicate with the other party, according to the previous style, read the other party's memory empty, it turned out that in the past twenty years, Balu will be Ling Chen's imparted knowledge, and many people argue, and put it into practice, especially in terms of population control, the demand for labor in the agricultural society, the increase in the premature death rate, and the lack of social security, so that farmers, as long as possible, will have more children, so as not to be old and have no support. In this case, the high birth rate, although there is also a high mortality rate as a hedge, but the population will always increase, coupled with the loose state control, no social security, land annexation is a natural thing, there are always people who are shrewd and diligent, and there are people who are stupid and lazy.

Once the land is annexed, it will cause a small number of people to occupy a large number of production materials, and these things cannot be circulated for a long time because of the underdeveloped commodity economy, and there is no economic crisis in feudal society, but most of the rich landlords have rotten grain, and there are countless people who have frozen to death outside, which is the root of the agricultural social cycle.

And the knowledge that Ling Chen taught the other party makes this possibility low, or even disappears, keeping the population within a certain range, and then doing a good job in the upper distribution, can make the entire agricultural society self-sufficient for a long time. However, the premise is that it can only be implemented in a small place, and in too large a place, it is always impossible for the regime to control it in time due to problems in communication technology.

It turns out that from Baru's memory, he controlled the city of zhì. It's also his territory. According to the Earth algorithm. It was about a thousand square kilometers, and he set up a academy with this knowledge and taught his disciples, who acted as bureaucrats according to this knowledge and governed the people at the same time, always keeping an eye on these indicators, land annexation, and population growth. The number of major landlords and the living conditions of the people are to make targeted adjustments to the policy, including encouraging births, restricting births, distributing materials, and cracking down on those big landlords.

Because this knowledge was widely spread, the enlightened landlords also understood, and of course there were people who were overly greedy, but that was to separate the landlord class. The implementation of these policies is also understood by those with foresight and does not attract opposition. The resistance is not great.

In this way, the city under his rule was the best of all the nearby territories, and the people lived and worked in peace and contentment, although they could not resist natural disasters and diseases, but at least there were far fewer man-made disasters.

Therefore, the common people are also very supportive and loving to him, and he already has the title of sage, as for other nearby territories, some are also willing to learn from it, and some are short-sighted and don't care at all, anyway, the chaos is hundreds of years at a time, and they just gather by themselves now.

After Ling Chen saw it, he felt that this civilization should have been successful, this civilization could survive in an agrarian society for a long time in this way, and there was no need to progress to the industrial age, and then fly to the universe and the like, but this could not be said to be that this civilization was under his rule, because now only Balu could enter.

However, Ling Chen also found a way, after a long period of research, he also knew the method, this Balu himself is a medium, the basic composition of his body, is the key to quantum communication, so as long as he is given a memory, let him die, scatter the ashes to every part of this planet, you can let the humans of this planet enter the virtual world, at most, open up a separate scene for them.

…………

"When I die, you will scatter my ashes all over the earth," said Balu to his disciples at the Bashan Academy, and as for his son, he did not pass on his position to his son, but to one of the students who understood his scriptures best.

"Know, teacher" Ancient feudal society, the obedience to the master is very large, heaven and earth monarch teacher, this is to reduce the cost of governance, and the use of an order, can be spontaneously maintained, without the need for rulers, always with law enforcement officers to maintain.

"Stand down, and Babs remains," he said, as Babs was his chosen successor.

"Teacher," Babs knelt down, he was originally only a child of a poor family, after entering the academy, he studied hard, and was able to go deep into the fields, trying to implement Balu's ideas, sorting out those private loans, reducing the burden of the people, and inhibiting mergers, these things are not easy to do, and it takes a lot of energy, if they are just ordinary nobles in feudal society, they would rather spend these time enjoying singing and dancing, and having fun, just like Balu's own son.

Although his son can't be said to be unfilial, after all, the environment affects him, and he can't endure hardships like Balu, and he is not willing to care about the food and drink of those ordinary people.

The city guards, unlike the soldiers of the feudal society, have some ideas, Balu are selected from the children of the peasants, and a small number are selected from the landlord class, so that they understand that the soldiers are to maintain the peace and contentment of these people, that is, their own families, and to implement his policies, which is also for this purpose, so these armies still have a great public heart, not the same as ordinary feudal troops, just for private individuals, the so-called imperial court, is only an abstract concept, and the real allegiance is the food and military salaries issued by the imperial court, Or the fields that are divided, they will not take into account any great righteousness.

But the city guards are different, they are from the township, the people around them are familiar with them, they are also familiar with the villagers, and they understand that the implementation of those policies is to let everyone live and work in peace and contentment, as long as a concept becomes a collective concept, it will be automatically inherited and retained, and it will be maintained spontaneously, because it is ultimately beneficial to everyone.

"Well, I have a great secret, and I haven't told anyone," he said as he was about to close his eyes, when he suddenly struggled and said something that surprised his disciple.

"When I was depressed in my early years, I once went to a temple, and in that temple, I had a dream, and in my dream, I met an immortal, and the immortal told me what to do, and you learned those things in the academy, they were all taught by the immortals," he said slowly.

"Teacher? Could it be that the rumors from the outside world are actually true? Babs couldn't believe it, and some people who were jealous of the teacher spread rumors that he had received these strange remarks from the devil, but the peasants and townspeople who had received the benefits were-for-tat, saying that they were taught by immortals.

"Although they are just guessing, they are about the same, except that although I have seen the immortals, there are only a few words that I really say to the immortals" Speaking of this, Balu coughed twice.

Babs didn't dare to ask any more questions, the teacher ran out of oil, and every word had to be memorized. (To be continued......)
