Xiaohe listened, so he asked:

If this is the case, then it also means that the races that are most able to replicate their own offspring will be able to achieve their own immortality. If this is the case, then the number of people will increase without limit, and will not this lead to a shortage of resources, and even war? ”

Runzhi listened, so he smiled, and then said:

In fact, what you are talking about is also a problem that most ordinary people are worried about, in fact, with the increase of population, it is true that if the material growth cannot keep up, it may cause a shortage of resources. As long as we see the shortage of resources, it naturally has a certain relationship with the population, but the most fundamental relationship is not the population, but the way of producing resources. In fact, we will find that in primitive societies, in addition to grain, only Shengping is the most valuable, that is to say, animal skins are the most valuable, why is this? This is because at that time, only animal skins could be used as clothing, and whether you could only know that animal skins were limited, that is to say, whether you could know that animal noses were limited, and how many animal noses could be used to know how many people, that is, if there were too few animal skins, then people would freeze to death because there were no animal skins as clothes. At that time, people will think that there is a limit to animal skins, and there is only one beast we can hunt, so how can we reproduce a population on a large scale? There are only a few devices that can give birth, so will people die in this natural world in the bare because they don't have animal skins to wear? This is indeed the case, that is, when there are few animal skins, all those who do not have animal skins as artists will die under the ravages of nature. At that time, people did not know that there was a more useful natural material, that is, linen cloth, and then silk, and at that time people began to have new clothes, and at that time, people no longer only thought that animal skins were limited, and if so many people were produced, then so many people would die because of the lack of animal skin clothing. I don't think that although the evaluation is limited, but the evaluation is gone, but there is the simplicity of producing linen linen, far more than people imagine, at that time people want to get animal skins, they must go hunting, and the prey of hunting is limited, so the population has always stayed in a very small range. ”

Runzhi paused, then continued:

"After the appearance of linen and linen, people no longer had to worry about the size of the population, it was up to the skins to decide. After the advent of linen, the pressure on society was no longer that people were afraid to give birth to the next generation and worried that because the hides were not enough for the next generation, they no longer had to worry about dying because there were too few skins. Therefore, after the appearance of sweater rags, that is to say in our Huaxia, that is, around the time of the Shang Dynasty, when linen cloth first appeared, the population almost achieved a linear rise. Later, when I arrived at the end of the Qin Dynasty and the beginning of the Han Dynasty, the first silk began to appear in front of the world. At this time, it was also the time when the population of China began to break through the 50 million level. By the time of the Tang Dynasty, the clothes at this time not only had the previous linen, linen, and silk, but also more other kinds of cotton cloth, and even other kinds of fine clothing. At that time, people not only had countless clothes to wear, but most people no longer had to worry about the lack of clothes, and let their children die after birth because they had no clothes to wear. At this time, people really began to worry about food, when there is more food, people will produce more children, when there is less food, the next generation will be produced, and even wars will break out, resulting in a large reduction in the existing population. At this time, the real restriction on the size of the population began, and it turned from clothing to food. But by the time of Wu Zetian, some changes had taken place at this time, and Wu Zetian encouraged people to invent some new farming tools, and asked many officials to carry out a large number of promotions. ”

Xiaohe poured a cup of tea for Runzhi, Runzhi very politely picked up the cup made of gold, took a sip, and immediately felt a very comfortable feeling, and immediately realized that this tea was an authentic Wuyi Mountain big red robe.

Runzhi took a sip of tea, and then said:

"During the reign of Wu Zetian, because Wu Zetian achieved large-scale improvements to agricultural tools such as iron plows, and carried out large-scale promotion, so that the existing cultivated land was more easily cultivated, people could produce more food crops with fewer people. At the same time, during the reign of Wu Zetian, through the reward of farming, even those who produced a large number of grain matches could be exempted from certain taxes or reward officials, so that the output of grain cloth was greatly increased. This is also similar to the Shang Dynasty in the Qin Dynasty, when officials were also awarded according to the amount of grain and cloth produced, and even exempted from taxes and awarded official titles. Of course, there was no awareness of environmental protection at that time, and at that time, if people cut down trees on a large scale, they needed to ask the local forest ranger to approve the tree cutting. At the same time, at that time, Wu Zetian encouraged the development of wasteland on a large scale, and turned a large number of wasteland into fertile land, which made the area of cultivated land about five times as much as before. It was at this time that the population had increased from about five times the previous population. It has achieved the glory of a new period, and also laid a solid population and material foundation for the subsequent Kaiyuan Dynasty. In this process, there is one person who must be mentioned, and this person's name is Di Renjie. In fact, the reason why Wu Zetian can have such a mind is naturally closely related to the man behind him. In other words, at that time, it was impossible for Di Renjie, who was born in the Shu clan, to ascend to the throne of the emperor. Because if he seizes power and ascends the throne, he will either face a great chaos in the world, although he can calm the chaos, but then a large number of people will suffer, and he, who is kind and thoughtful by nature, does not want to do so. Di Renjie's biggest purpose is to use political means to achieve his great responsibility of self-cultivation and governing the country and the world in a stable environment.

Therefore, he firmly and secretly supported Wu Zetian and offered advice as an important way for him to rule secretly. With the assistance of this very famous talent, Wu Zetian was able to quickly control the government at that time with the help of many means and even necessary killings, because he had the support of firm talents behind him. As the saying goes, those who win the hearts of the people win the world, and the real hearts of the people are first of all supported by the top talents born in the Shu people. ”
