Naturalization of the Ming Dynasty is the Ming people, which is customary, and there is no official document or proof.

But the Nationality Act fills this gap, giving it legal recognition and some formal ceremonies. Such as oaths, such as naturalization papers, and so on.

This is not just a sense of ceremony, but a more solemn and solemn appearance. Don't think it's so simple to become a Ming person, and Daming is not accepted by everyone.

Li Guozhu understands, and Dong Yingju also understands.

Setting a threshold and taking an oath of naturalization does not guarantee that naturalized people will be loyal to the Ming Dynasty. Not to mention naturalized people, it is a Ming person, who knows if it will be treason and join the enemy?

But they didn't know that the promulgation of the "Nationality Law" actually had another profound meaning, which would become the reason for the Ming Dynasty to go to war with foreign countries in the future.

Because no one has ever heard of the term "extradition", although the pursuit of treasonous traitors has long been the case.

As long as the Ming is strong enough, the army is invincible, and the traitors will have no place to stand. No matter if you run to the ends of the earth, you must be brought to justice, punished by the law, and punished as a latecomer.

"First naturalization, then inspection, two years to speak Chinese, five years to pass the exam, can be regarded as officially joining the Ming Dynasty." Dong Yingju smiled, stretched out his hand to stroke his beard under his chin, and said, "Long live the deep meaning, can Master Li understand?" ”

"Xia Guan understands." Li Guozhu arched his hand, "Long live this is a wise policy, and it can be implemented first in this county." ”

"Very good." Dong Yingju nodded, he just said hello first, the will of the saint is not good, who dares to disobey it?

After a pause, Dong Yingju said again: "The medical officer sent by the Holy Lord, carrying a prescription for the treatment of malaria, has arrived in Mekong Province. ”

Li Guozhu's eyes lit up and he praised: "This is a great joy, it relieves the people's worries, and the immigration work can be carried out smoothly." ”

In the southwest, the heat is unbearable, and mosquitoes and flies breed. The most prevalent disease is malaria.

Moreover, due to the limited level of science and technology, people do not know the cause of malaria. Some to miasma, and some to unclean.

The emperor naturally knew that it was a mosquito bite, and he also knew that there was a special medicine for the treatment of malaria.

Cinchona was not available for the time being, although he had already found a way to do it through missionaries and planned to plant cinchona trees in the South Seas.

And what can be immediately applied to practice seems to be the green song, commonly known as the stinky song plant.

Of course, the emperor did not know the extraction method of Qingsonglin, and also thought that it was impossible to achieve it with the current technology. But which of the two methods works, he can let the doctor try to squeeze the juice with Qingsong, or boil water with Qingsong.

At the same time, now that the cause of the disease is known, mosquito nets, perfumes, mosquito coils, etc., which prevent mosquitoes, can also come in handy.

At the behest of the emperor, both the Tai Hospital and the Medical College conducted experiments and research in this area, and finally verified that the juice squeezed with Qingsong has a curative effect.

Don't underestimate this method of preventing and curing malaria, but it removes a major obstacle to expanding its territory in the warm and humid lands of the South Seas. Not only will it reduce the number of injuries and illnesses in the army, but it will also reassure immigrants.

Dong Yingju laughed and said: "This official has seen the prevention and treatment plan brought by the medical officer, this disease can be prevented and treated, and it will be implemented, and there is nothing terrible about the miasma in the land of the South Seas." ”

Li Guozhu hesitated for a moment, and asked tentatively: "I don't know if this prevention and control method is kept secret?" ”

After a pause, he added: "It's not for outsiders, but for maritime merchants, and the maritime merchants who run in the South Seas give them an extra layer of protection." ”

Dong Yingju smiled and said, "Anyone who is a citizen of the Ming Dynasty can be informed." Even if it is a barbarian, this official can't keep it a secret for too long. ”

There is no need to block the secret, and it won't last long. After all, if you want the people to know how to do it, it is impossible for thousands of people not to be learned by outsiders.

Li Guozhu immediately put his mind at ease, thinking that even if he didn't tell the Maritime General Association, his father-in-law would get a cure for it.

You must know that the emperor's grand ambitions, the maritime merchants will always be the first to know and the first to act.

He got the post of county commander in Mekong Province, but it was just a matter of experience, and it would not last long.

Li Dan and Yan Siqi have already set their sights on the vast land of Nanyang, and under the instruction of the emperor, under the guise of commerce and trade, they will infiltrate and spy until they occupy a larger territory.

According to the emperor's promise, whoever established the meritorious deeds, the imperial court would not hesitate to reward the knighthood and give a certain fief.

This is the first time in the history of the world, giving the merchant a real title, a real fief. Even for the founding feats of this dynasty, there are very few people who have received this treatment.

Obviously, the emperor was also optimistic about the pioneering spirit of the maritime group, so he gave it convenience first, hoping that they could succeed and become an example for others.

"Liaodong has been flattened, the whole country is celebrating, and Mekong Province should also congratulate Daming and the Son of Heaven." Dong Yingju smiled, showing a different ease and happiness from before, "You have already seen the layout in the city, right?" ”

Li Guozhu hurriedly nodded and said, "The lanterns are colorful, and it is very grand. In the county town under the rule of the lower officials, there is also the same celebratory atmosphere, but it is not as good as the government city. ”

Dong Yingju smiled and talked with Li Guozhu for a while before letting him leave.

Dong Yingju was the only one left in the hall, he pondered for a long time, picked up the thoughts interrupted by Li Guozhu again, picked up the pen and paper, and began to write a secret note for the emperor.

There are some things that Dong Yingju did not tell Li Guozhu. It's not that they don't trust, but they have nothing to do with Li Guozhu.

The emperor asked Dong Yingju about the situation in Mekong Province, mainly the situation of the Champa state in the north, and the situation in the north of the Champa state and the south Nguyen in the north of the Champong state.

At that time, Annam was divided into two divisions, the north and the south, and the army was exchanged for many years, and the north Zheng and the south and Nguyen won and lost each other, and no one could defeat the opponent in one fell swoop, so as to unify Annam.

And the Champa state was already weak and about to be destroyed, but Nam Nguyen did not free his hands to allow it to exist respectfully.

However, the Ming Dynasty expanded land reclamation in Mekong Province and sandwiched the Champa state in the middle.

In such a situation, Nan Ruan may be even more difficult to start. They are not stupid, and keeping the Champa State as a buffer is much less pressure than facing the powerful Ming Dynasty.

In Dong Yingju's view, the temporary maintenance of the Champa state is more conducive to the development of Mekong Province. After all, now Mekong is expanding mainly to the south, to the sea.

At the southernmost tip of Indochina, it is significant to have a port. As a transit point to Siam and the Malayan Peninsula, it provided greater convenience for maritime merchants heading to the South Seas.

At the same time, this is also what the sailors require, to be able to better control the South China Sea and resist the Xiyi.

"Long live the Ming Jian, if Mekong Province can add another 100,000 immigrants next year, the land reclamation will be enough for three years. And the army of water and land has more than 10,000, and it can sweep away the barbarians, and it is invincible......"

Dong Yingju put down his pen and felt that Liaodong was pacified, and the imperial court should be able to give greater support to Mekong Province.
