After receiving the various constraints and orders from Zhu Yunwen and Zhu Yuanzhang regarding the redistribution of power, the vassal kings dared not speak out and could only silently endure them.

And they all had to act very obediently, praising Zhu Yuanzhang and Zhu Yunwen for making excellent decisions.

In fact, they had no other choice but to do this. After all, putting aside Zhu Yuanzhang, Zhu Yunwen's position in the Ming Dynasty was unshakeable.

How could those princes dare to disobey Zhu Yunwen in the slightest? So whatever Zhu Yunwen said was law, and even if they were not entirely satisfied, they had no choice but to listen.

That's something that can't be refuted.

As a result, these feudal lords began to marry only one wife. Those who already had concubines were all divorced if they hadn't borne children, and those who already had wives were no longer allowed to marry.

The family planning policy in the Ming Dynasty began with the princes. Of course, this family planning policy only applied to the princes and did not apply to ordinary people.

With the threat of the barbarian king resolved, a weight was lifted from Zhu Yuanzhang's mind.

At this point, in Zhu Yuanzhang's view, there seemed to be nothing in the court that he could worry about.

After all, people's lives are getting better and better, and the economy of the Ming Dynasty is becoming more and more impressive.

Its military strength is also incredibly powerful, giving it an overwhelming advantage over other countries.

The local people's education, medical care, and living standards were all very good, so there was basically nothing for Zhu Yuanzhang to worry about.

Under these circumstances, Zhu Yuanzhang practically lived the life of a retired emperor.

He would only occasionally inquire about state affairs each day, and basically left most matters to Zhu Yunwen.

During this period, Zhu Yunwen, along with the three Yangs of the cabinet, continued to improve some of the Ming Dynasty's policies.

In addition, Ma Sanbao lived up to his mission, continuously strengthening various trade exchanges overseas and opening up a maritime Silk Road-like route, establishing a series of trade and economic cooperation with various countries overseas.

Sell ​​the things from the Ming Dynasty and buy things from outside.

Such a transaction would also increase the revenue of the Ming Dynasty, and at the same time, it would allow the people of the Ming Dynasty to obtain more abundant resources from overseas.

In this day and age, the resources available are really nothing more than gold, silver, iron, copper, and various grains, crops, fruits, and so on.

This directly led to the fact that people in coastal areas could not only make a living by fishing, but also become wealthy through trade and cooperation with overseas countries.

Upon receiving this news, Zhu Yunwen was deeply moved, realizing that coastal areas indeed have their advantages.

It's already starting to show up now.

At the same time, Zhu Yunwen was also thinking that the Ming Dynasty had developed to such a point in such a short time that many things had appeared hundreds of years earlier.

So, does he have the ability to continue to transform the Ming Dynasty into an era that is infinitely close to modern society in later generations?

Although it was difficult, Zhu Yunwen felt it wasn't impossible.

After all, he has now produced powerful weapons such as guns and cannons, and has also repaired cement roads and manufactured products like floral water.

If he had more time to recall the knowledge he gained in the world before his transmigration, it wouldn't be impossible for him to create the Ming Dynasty as a society infinitely close to modern times.

Thinking about this, Zhu Yunwen continued to ponder how to use his knowledge to create something.

The rapid progress in later generations was mainly due to breakthroughs in science and chemistry.

However, these things can only be achieved through the joint efforts of all those who study science and chemistry.

It wasn't something Zhu Yunwen alone could have brought about.

All he can do is create something new, so all he can do is proceed step by step.

For example, his current idea is whether it is possible to build a steam train, an idea that has been in his mind for a long time.

After all, he had told Zhu Yuanzhang and Zhao Qingzhu countless times that he would make the Ming Dynasty more perfect and more advanced.

Now, the changes Zhu Yunwen has brought to the world are merely cement, coal, toilet water, bicycles, and various firearms and bombs.

But that's still far from enough.

After having the idea, Zhu Yunwen summoned the people from the Ministry of Works to his Eastern Palace, where he drew a model of the train using blueprints.

Actually, trains are relatively easy to build; the key is the steam system.

This thing must be able to be manufactured in order to pull a train; the steam system is relatively easy to understand.

It is also the most primitive train power system, the principle of which is to build a coal-fired steam boiler.

These things are easy to understand when separated; burning coal is simply burning coal.

Coal has been extensively mined in the Ming Dynasty, and the coal mining industry is now very mature and can be found in various places.

Moreover, due to the enormous amount of coal mined, the price of coal is very low, and the cost is also very low.

So coal is not a problem.

Steam is easy to understand; it's simply water that's heated and turned into gas, expanding infinitely.

The boiler is even simpler; it's just a sealed boiler. You combine these three things, pour water into the boiler, heat it up, and leave only a small opening in the boiler's location.
