After the military occupation of Annam, the newly established Jiaozhi Political Secretary was directly led by high-ranking officials such as Lu Jiayu and Zhang Huangyan, who were familiar with colonial rule and assimilation education.

The Thirteen Prefectures Governors, which were established on the basis of the Thirteen Xuanfu Divisions under the former Annan Metropolitan Control Division, were directly transferred from the local officials who were familiar with the assimilation of foreign races in Monan and Mobei, or from the grassroots officials who had experience in the southwest to reform the land and return to the stream, and immediately began to rule the Jiaozhi sinicization.

During the Yongle period, the Ming Dynasty's rule over Jiaozhi failed, and a big reason was that only the military occupation and the appointment of upper-level officials were carried out, and the ruling basis of Jiaozhi was not fundamentally changed.

It is not only reflected in the unified transfer of grass-roots officials from the Ming Dynasty, but also in the fact that His Majesty the Ming Emperor immediately issued an order to join the Ming household registration, follow the customs of the Han people, and change the clothes and crowns, the Ming Dynasty will not confiscate their private property and land and protect them, and the people at the bottom will also enjoy the same welfare treatment as the Ming people.

However, for those who refuse to change customs, they will be directly transferred to the second class and incorporated into the slave labor camp to participate in the construction of the territory of the Jiaozhi Political Envoy, and for those who intend to resist, they will directly implement the joint sitting system, that is, if one person from each A resists the Ming Dynasty, all the people in the first class will be killed.

On the one hand, there is no need to pay taxes and serve in conscription, and the welfare temptation of receiving free education, and on the other hand, there is no schooling, no military service, no officials, and the obligation to pay poll tax, and on the other hand, the people of all walks of life in the Jiaozhi Political Envoy Division are naturally willing to choose to obey the rule of the Ming Dynasty.

However, in order to prevent the remnants of the separatist regime of the former Annam Kingdom from having a chance to revivenation, the four major families with the surnames of Zheng Nguyen, Vu Mo, and their affiliated big landlords in Jiaozhi were directly slaughtered on charges of aiding thieves or failing to suppress thieves.

Although this led to a sporadic rebellion in the next few years, it also completely stifled the chances of these indigenous families trying to become the owners of the land again.

In short, in order to make this land completely become a province of the Ming Dynasty, it is necessary to adopt the means of iron-blooded pressure and cultural export at the same time.

Even for this reason, the Ming Emperor Zhu Youxiao also specially ordered to move 100,000 wealthy households in the south of the Yangtze River to enrich Jiaozhi, which not only weakened the control of the gentry who had transformed into merchants over the south of the Yangtze River, but also allowed them to take root in the Han culture they mastered in Jiaozhi, a land that had not yet been fully developed.

However, what is unexpected is that less than a month after the Ming Dynasty completely occupied the Jiaozhi Political Envoy.

His Majesty the Emperor of the Ming Dynasty, Zhu Youxiao, decided to strike while the iron was hot according to the proposal of the Ministry of War, and ordered the mobilization of the First Army to the south and the Fourth Army, in addition to the troops left behind in Jiaozhi, a total of more than 150,000 troops directly from the firewood stick, on the grounds that the Zhenla Kingdom and the Later Li Dynasty were embarrassed to annihilate and not help the Ming Dynasty to suppress the thieves.

The kingdom of Zhenla was caught off guard, and their army was still limited to the era of spears and swords, and even many tribes were very short of iron tools or iron-making skills were not high, so that some armies even only used wooden sticks and bamboo as weapons.

Because of this, in the face of guns and poison gas bombs, these indigenous armies naturally could not resist the attack of the Ming army, and at most they resisted stubbornly through the mountains and jungles.

According to the plan of the Ministry of War, since it was so easy to fight an Annam, it was decided to directly pacify Chenla, Siam, Laos, Donghu and other countries within a year, and then unify the entire Southeast Asian Peninsula and completely divide Nanyang into the Ming Inland Sea.

However, the unification of the entire Southeast Asian Peninsula is not really smooth sailing, as the Ming Dynasty's ambition to unify the entire Southeast Asian Peninsula and include it in the scope of Ming rule is becoming more and more obvious, some Southeast Asian separatist forces that have not yet had time to be destroyed are no longer involved in internal strife, and are busy trying to find various ways to resist the Ming Dynasty.

Due to the complex geographical situation in this area, it also caused certain difficulties to the war process of the Ming Dynasty.

However, Zhu Youxiao did not give up, but simply transferred a total of 200,000 troops of the Second Army and the Third Army to the Southeast Asian battlefield again, and went out to fight from Guangxi, Yunnan and other places.

According to Zhu Youxiao's intention, it was necessary to pull all the troops of the Ming Dynasty up and attack them in turn from all directions, so as to not only train the army but also plunge the local regime in Southeast Asia into the quagmire of war, and promote the intensification of its internal contradictions and its complete disintegration.

The South China Sea Fleet and the ocean-going fleet of the Ming Navy carried out shelling of various fortresses along the coastline from the South China Sea to the Bay of Bengal in turn, directly focusing on their rear bases.

Since then, from Yunnan to Guangxi, and then from Guangxi to Jiazhi, and then the entire sea area, the Ming Dynasty has basically been in a situation of strategic encirclement of Southeast Asia.

In addition, the Ming Dynasty directly used this to increase the army, and the soldiers who had gone to the local military academy instructors or garrison officers and soldiers after leaving the army were called back, and immediately expanded the number of recruits, directly expanding the army by 600,000, and after three months of training, the army of 300,000 was directly dispatched to the south.

As a result, the entire military industry, which had already been losing money, was completely stimulated, and several large-scale manufacturing workshops under the Ordnance Department immediately changed their production mode and began to produce guns and ammunition on a large scale.

The decline in employment due to the improvement of production technology and the influx of immigrants has also begun to pick up.

Because of this war, Daming's economy continued to enter a state of benign development.

As the newly occupied territories continued to expand, the construction of major communication arteries that played an important role in the control of the newly occupied territories required the immediate construction of some key passes, as well as the logistical military transportation and the repatriation of raw materials plundered from these newly occupied territories, all of which required a large amount of manpower, i.e., slaves.

As a result, the aborigines were taken captive from the colonies or directly from the newly occupied territories, and the trade of white pigs and Kunlun slaves from places like Europa and Africa became more and more popular.

In order not to make these foreign populations completely overwhelm the native population of the Ming Dynasty in terms of population.

Zhu Youxiao had no choice but to order that in the future, those who were not registered citizens in the territory of the Ming Dynasty would be forcibly castrated, and those who were not castrated would not be allowed to be trafficked into the territory of the Ming Dynasty, and their human trafficking companies would also suffer heavy fines.

In this way, the Jiaozhi political envoy and the local people who had been Sinicized in the areas previously occupied by the Ming Dynasty were fortunate to escape the fate of the heirs, while the local people who were unwilling to accept the trend of assimilation and were willing to work as low-level slave laborers had to face the fate of being cut off from their descendants.

However, because of the huge number of slave laborers to perform this operation, the Ministry of Health had to send a large number of medical personnel to help these human trafficking companies, and Zhu Youxiao also ordered the Ministry of Health to allocate 1 million silver dollars to provide postoperative medical treatment support and surgical instrument support.

This also reflects the generosity of the Ming Emperor.
