After conquering the entire territory of Korea and completely controlling Korea, it was time to deal with prisoners of war and other issues.

For a total of more than 400,000 Korean prisoners of war and about 60,000 Japanese prisoners of war who returned from the Korean captives, Zhu Ci sent them to the Mongolian steppe without any suspense to participate in the construction of cities and the transformation of Mongolia, which was also an earlier idea.

According to Zhu Cijiao's estimate, with the addition of these hundreds of thousands of prisoners of war, the construction of Mongolia can be completed more than twice as much as the time.

After all, they were coolies, and in order to leave a glimmer of hope for those prisoners of war and let them work in peace, Zhu Ci ordered the Korean prisoners to work in peace for a period of ten years, and after learning Chinese characters, they could be released back to their hometowns after ten years.

This is a glimmer of hope and a kind of expectation, and only with hope and expectation will they not despair and will it be more convenient to govern.

Of course, the past ten years were limited to Korean prisoners, and Zhu Cijiao, a prisoner of the Japanese invaders, was not so easy to talk to.

After the defeat in Seoul, the Japanese invaders raped and plundered several Korean cities in North Korea in the course of their rout, and indiscriminately killed innocent people, resulting in the tragic death of hundreds of thousands of innocent Korean people.

Although the target was Koreans rather than Han Chinese, the ferocity and perversion of the Japanese still made Zhu Ci uncontrollable anger, so in order to punish the Japanese and to show the evil anger in his heart, he did not hesitate to extend the period of ten years for the Korean prisoners to twenty years, and the work assigned to the Japanese would be the hardest, making them pay for what they did.

Ten years is not a long time, but it is not a short time, but after all, there is an expectation, so after the news reached the Korean prisoner of war camp, it did not cause any waves among the Korean prisoners.

On the contrary, it was the Japanese Invaders, they felt that because of the prejudice of the Ming Dynasty, they had to work twice as long as the Koreans, which made many of the Japanese prisoners feel desperate and unconvinced, and began to make a fuss, but unfortunately they were greeted not by the compromise of the Ming Dynasty, but by cold bullets, after mercilessly executing hundreds of Japanese who dared to make trouble, the remaining Japanese Kou were immediately honest, although they were still unwilling, but the innate servility and the experience of hundreds of people also made them no longer dare to resist.

After dealing with the issue of prisoners of war, the next step is undoubtedly how to transform North Korea and make it truly incorporated into the Ming Dynasty.

The territory of Korea is not large, at least it is larger than most of the current provinces of the Ming Dynasty.

"Your Majesty, the minister proposed to divide Korea according to the four counties of Han divided by Emperor Wu of the Han Dynasty, divide Korea into four, set up four prefectures, and directly incorporate Liaodong!" In the imperial study, Li Yan proposed to Zhu Ciji.

"No!" Zhu Ci thought about it, and after a while, he shook his head and disagreed.

At present, the administrative system of the Ming Dynasty is divided into three levels: provinces, prefectures, and counties, and if North Korea is divided into four and incorporated into Liaodong, with the area of North Korea, after it is incorporated into Liaodong, the area of Liaodong will be too large and not suitable for jurisdiction.

Moreover, if North Korea is a newly occupied area, the people in it are different from the Ming Dynasty in terms of language, writing and many customs, etc., and they must be transformed, and the transformation of North Korea requires the dedication of a provincial governor, so in order to facilitate the reunification and transformation, Zhu Ciji finally decided to set up a province in North Korea!

Of course, Zhu will not really set up the whole of Korea directly as a separate province.

"In this way, Tielingwei and Xianxing Mansion will be merged into Liaodong, and the rest of the places will establish a separate province, take the name of Lelang County in the Han Dynasty, and become Lelang Province!" Zhu Ci thought for a while and decided.

Tielingwei and Hamhung Province occupy about one-fifth of the territory of North Korea, but they are not densely populated places in North Korea, the population is not large, and the annexation of Liaodong is not enough to make the jurisdiction of Liaodong too large, and at the same time firmly control the Yalu River in Liaodong, killing two birds with one stone.

"The Emperor Shengming!" Since Zhu Ciji had already decided, Li Yan had no objections, and immediately decided like this.

In order to truly transform North Korea, it is also necessary to unify the Korean language and script, etc., and only when there is cultural unity can it be truly assimilated.

Zhu Cicheng planned to set up schools in all counties and towns of North Korea to teach all Koreans to learn Chinese, Chinese characters and Chinese history, and in order to stimulate Koreans to agree with their hearts as soon as possible, Zhu Ciji also ordered the establishment of institutional restrictions.

North Korea is different from the Ming Dynasty, when the Ming Dynasty opened the country, there was a Zhu Yuanzhang who really considered the people, and the agricultural tax was set very low, and Zhu Yuanzhang was only fifty taxes when he was established, even when Emperor Chongzhen was the most difficult, the agricultural tax of the Ming Dynasty was only twenty taxes and one one, which was still lower than all dynasties.

North Korea followed the original system of the Goryeo Kingdom, whether it was agricultural taxes or other aspects, the oppression of the people was much higher than that of the Ming Dynasty.

Moreover, since Zhu Ci ascended the throne, the Ming Dynasty has undergone several reforms, not only reducing the agricultural tax to the level of 30 taxes again, but also canceling the forced labor, and forcibly restricting the price of landlords' land leases, it can be said that the ordinary people of the Ming Dynasty are happier than all dynasties in history.

If the Ming Dynasty also implements the same policy in the territory of the DPRK as in the interior of the Ming Dynasty, the people of the DPRK must be extremely welcome and look forward to it.

However, Zhu Ciji does not plan to do this directly, but to link the benefits of the Ming policy with cultural identity, and only Korean families who can speak Chinese and write Chinese characters are eligible to enjoy the benefits of the Ming policy, enjoy the low agricultural tax, exemption from forced labor and other policy benefits of the Ming Dynasty, while the families who have not learned Chinese and Chinese characters for a day still follow the original tax rate and policy of North Korea.

Zhu Cijiao wants to create a way to divide Koreans into two classes, and Koreans who can speak Chinese and Chinese are the first class, and they can enjoy the benefits of the Ming Dynasty. Those who did not know Chinese and Chinese characters were still being squeezed under the old Korean system.

This is also a strategy of killing two birds with one stone, only comparison can make people see the gap, see that the Ming system is superior and happier than the original Korean system, so that more and more North Koreans identify with the Ming Dynasty, and hope that they will truly become a Ming people, which will continue to stimulate their enthusiasm for learning.

At the same time, some immigrants are also needed, and the Korean royal family and nobles have left a large amount of land, as well as several cities that were slaughtered by the Japanese invaders, which are suitable for the resettlement of some immigrants, and the immigration to North Korea will be carried out simultaneously with the immigration to Mongolia.
