Astronomy can be regarded as the first thing that stimulates human civilization, after all, the more people know, the more they will feel their own insignificance, and the hidden unwillingness and unwillingness of human beings to admit defeat or the pride of being the top of the whole world for thousands of years has stimulated human beings to exhaust all ways to conquer those vast and boundless universes.

Just as in the early days, human beings conquered animals, conquered the earth, and even conquered the sea, the emergence of astronomy tore the veil of the dark Middle Ages, so that a West far behind the East China began to gradually catch up, and took advantage of the hundreds of years of Manchu wild boar skin notice, completely caught up with and surpassed the East China, and the century of humiliation of China began.

Although it is a bit biased, for Cao Cao, he thinks that if there is no astronomy, then there would not be so many Western historical celebrities in history, and there would be no final Renaissance, but always under the rule of Christianity.

It is precisely because of this that Cao Cao values the subject of astronomy the most, and Cao Cao, who was originally a little distressed because he had no good excuse to set up an astronomical discipline, thought of what he saw today, his face was full of smiles, and the origin and usefulness of the nine numbers still gave Cao Cao an excuse to set up an astronomical discipline.

Of course, Cao Cao actually understood in his heart that even if the astronomy discipline was established at this time, if he wanted to see success, not to mention a few decades, even if it was one or two hundred years, it was very likely that he would not see any achievements.

However, just as Europe has spent hundreds of years and countless lives in the dark Middle Ages, for the future of China, for the Chinese civilization to continue to develop after his death, even if he can't see it in his lifetime, Cao Cao believes that the brilliance of astronomy will definitely be seen among his descendants!

However, although there is already an excuse to set up an astronomical discipline, it does not mean that Cao Cao will set up this discipline at this time, not that Cao Cao is not in a hurry. If he was really not in a hurry, then Cao Cao would not be so excited after getting that excuse again.

The real reason for Cao Cao's preparation to postpone the establishment is actually one point. That is, the world has not yet been settled, and Cao Cao doesn't know how much money is needed for astronomy, but as long as he thinks about the academy of sciences in later generations, Cao Cao doesn't think that he has so much money when the world is not yet flat, and he doesn't think that the civil and military forces under his command will really let him come at will.

If only he Cao Cao had set up the discipline of astronomy. As long as the power of the astronomical discipline, a big spender, comes to the cost, Cao Cao absolutely dares to guarantee that his own Wei Mansion will definitely not be peaceful, and it is difficult to say whether he will die, but he can still guarantee it once a day.

After dividing this matter into the matter of the future when the world was unified, Cao Cao, who had recovered from his contemplation, also had the time and energy to take a good look at the city under his rule in the next part of the journey.

There is a saying in history that the scholar is every three days, and he should be impressed. This sentence can actually be placed on the Chen capital, but I haven't seen it for just a month, the prosperity of the Chen capital is more than a month ago, and at the same time, on the street, you can see from time to time, one by one, the northern barbarians wearing nomadic clothes are walking on the road, but compared to the hatred and fear of the barbarians a few years ago, the Han people, especially the local Han people in Chendu, only despise and ignore and be proud of these barbarians.

Because they know it well. These barbarians came from a tribe called Wuhuan in the northern grasslands, and this tribe had long been subjugated to the command of the Duke of Wei, so for the people of the Han land, these barbarians. It's just that Cao Cao has a dog, why should people be afraid of dogs?

Seeing these Wuhuan people with their hair scattered, Cao Cao patted his forehead, as if he suddenly remembered something, and asked Chen Gong behind him: "Gongtai, there is one thing that I almost forgot about it." How about the Wuhuan people who moved into Chendu in Anxin North District, but what is abnormal? ”

Although Wuhuan has surrendered, it is obviously impossible to make Cao Cao believe in the discipline of the barbarians, so as early as when he led the army to return to the north, Cao Cao issued an order to move all the families of the upper echelons of Wuhuan to Chendu, not only to blackmail those Wuhuan people, so that they dare not think about anything, but more importantly, to gradually integrate Wuhuan and finally let the Wuhuan nation disappear completely.

In Cao Cao's heart, the relocation of the upper class of Wuhuan family to Chendu is only the first step, and in the future, Cao Cao will slowly disperse all the Wuhuan people on the grassland step by step, and move into the Central Plains separately, Cao Cao believes that with the unparalleled inclusiveness and assimilation of Han culture, the Wuhuan nomadic people may disappear completely in just a few decades, just like the barbarians such as the dog Rong and Donghu in the past.

As for the danger of moving these Wuhuan people into the Central Plains, Cao Cao didn't think about it at all, because it was impossible at all, not to mention that at that time the Wuhuan people were scattered and moved to all parts of the Central Plains separately, just the huge population base of the Han people in the Central Plains was enough to eliminate those hidden dangers.

"Back to the king, those Wuhuan people are still law-abiding, and they haven't done anything, not only that, but some Wuhuan people are completely obsessed with the life of Chen Du, and they take the initiative to speak Chinese, perform Han etiquette, and wear Hanfu, so you don't have to worry,

It is impossible for these Wuhuan people to make waves in Chen Du. ”

Chen Gong didn't understand what Cao Cao thought, so he just told Cao Cao about the actions of the Wuhuan people in the past few days, and when it came to the Wuhuan people saying sinicization, Han etiquette, and wearing Hanfu, Chen Gong's face had a touch of pride, of course, not only him, but also Dian Wei and Xu Chu on the side, their own culture, can be actively imitated, how can they not be proud.

Speaking of which, many people in later generations believe that the national cognition of China has not appeared until the modern era in that hundred years of humiliation, but in Cao Cao's view, this is not very correct, in his opinion, the national consciousness of China was actually as early as the Spring and Autumn Period with the generation of culture and formally appeared.

With one of the five hegemons of the Spring and Autumn Period, Qi Henggong, Jiuhe princes, after a Kuang world, the national consciousness of China was actually born, and the people in the Central Plains at that time generally believed that the people outside the Central Plains were the four Yi, and no matter which country the people in the Central Plains were, they were all the same people, all of them were Huaxia or called the Central Plains.

It is precisely because of this vague and not too mature view that there was a Warring States period, when King Qin Zhaoxiang heard that Zhao State was attacked by barbarians and stopped attacking Zhao State, but was preparing for military warfare at any time to help Zhao State resist the barbarian things, if the national consciousness of China is really only in modern times, then these things would not have happened during the Spring and Autumn Period and the Warring States Period.
