With Lu Xiangsheng's monument in Beihai, the war of unification of the Qin Dynasty finally came to an end.

There was no strong enemy in the north, and the South was also completely pacified. Duke Mu fled to Myanmar with King GUI, some Ming Dynasty officials who fled to Yunnan and thousands of disabled soldiers and defeated generals. Qin Shuang also did not pursue, but began disarmament according to Qin Huan's order.

The fourth corps, the Fifth Corps and the 100000 troops of the first Corps totaled 300000, leaving only 20000 people stationed in Yunnan, 30000 in Guangdong and Guangxi, and the rest began to return to Huguang.

Because most of these soldiers are from Jiangnan and Huguang, they are not suitable for fighting in the mountains in the southwest. As the weather turns hot, a large area of personnel are acclimatized and unwell.

Similarly, only 50000 soldiers and horses were left in Northwest China and Sichuan. All the remaining soldiers and horses were retired and settled down in the local area.

So far, the field army of the Qin army, that is, a regiment in the northeast, a regiment in the north, a regiment in the northwest, a regiment in the southwest, a regiment in Guangdong and Guangdong, and 200000 troops returning from Yunnan, plus 30000 white pole soldiers of Qin Lihua and 5000 cavalry of Lu Xiangsheng.

Although the field army was abolished, the National Guard troops in all provinces were sent out in batches, almost all of them 17 or 18-year-old boys.

Qin Huan planned to rest for a year or two. After all the provinces in the world had settled down, the field army had been reorganized and the National Guard had been deployed, he would fight abroad.

In his opinion, a small country can send 10000 or 20000 troops, and a larger country can send up to 50000 or 60000 troops.

With the rise and reunification of the Central Plains Dynasty again, the surrounding countries have sent envoys to Nanjing to pay tribute and ask for the canonization of the emperor of the Qin Dynasty. Of course, some have come to ask for help, including the Lee Dynasty of Korea and the Ruan Dynasty in southern Vietnam.

Qin Huan was still busy in Wuchang with the arrival of many envoys. He had no intention of returning to Nanjing. Song xiance, who had just become the head of the Lifan academy, was also confused about what to do. Finally, he had to let envoys of all countries live first and then go to Wuchang to ask for instructions in person.

………

"Song Aiqing, who are the envoys of these countries?"

"Your Majesty, there are North Korea, Ryukyu, Vietnam, Nguyen, li..." Song xiance quickly replied, talking about seven or eight small countries in a row.

"Why did so many vassal states pay tribute?" Qin Yumei frowned at first. When the Central Plains Dynasty was strong, there were dozens of small countries that came to pay tribute, and there were more than a dozen. There were only seven or eight like today, which was unique.

"Your Majesty, some small countries in Nanyang have been destroyed by the red hair people. Even if they have not been destroyed, many people take into account the red hair people and dare not pay tribute."

Song xiance said angrily. Obviously, he also felt that there were a few countries to pay tribute. He was the head of the Li Fan court.

"What tribute did the messenger bring? Are there any beauties? " Qin Huan nodded noncommittally and asked, but he didn't seem very angry.

"There are no beauties under your majesty Hui. They are all local specialties." Song xiance's face twitched and answered honestly.

In fact, all countries in the past dynasties were not unwilling to offer beauty to the emperors of the Central Plains Dynasty, but the emperors did not like it.

Just like in the Tang Dynasty, marrying a princess to a foreign nationality is a charity to them, but letting him marry a foreign woman himself, even if he is a concubine, is an insult to them.

Not to mention the emperor, even those literati and bureaucrats disdain to take those foreign women as wives and concubines. At most, they are just raising their singing skills for fun. Anyone who gives a title will definitely be ridiculed. Dignitaries and dignitaries are like this, not to mention the king of a country.

Qin Huan obviously didn't think so. He hated that marrying a Han woman to a foreign nationality was actually an act of exchanging women for peace. So he coughed and said, "the rules of tribute have to be changed, and the systems of the patriarchal state and vassal state have to be changed."

"Your Majesty, please show me how to change and how to change?"

"Well..."

Qin Huan smiled and explained in detail the vassal system he had planned for a long time.

If you want to become a vassal state of Daqin in the future, first of all, the king must come to Daqin to accept the canonization. At that time, the emperor will give the king the great seal, python robe, jade belt, crown and canonization edict, and the king will also accept the protection of Daqin. No matter whether it is foreign invasion or civil rebellion, Daqin will send troops to kill or overthrow the king, Truly share weal and woe with the great Qin Dynasty.

Although the great Qin Dynasty would not interfere with the inheritance of the throne and military politics of its vassal state, there are several articles that must be observed and accepted.

The first is that the businessmen of the two countries can trade freely. The second is that the dependent country must use the currency of Daqin. The third is that the dependent country is not allowed to form an alliance with other countries without permission. If it wants to levy other countries, it must first report to Daqin and send troops to levy after obtaining permission.

Once the above articles are violated, it will be regarded as betraying the home country. The consequence is to destroy the country and kill all the king's family.

Of course, this is only the first step. The second step is that the Daqin society will set up a secondary school in each dependent country. All people in the country can participate in the assessment. After graduation, those with excellent results can go to the Daqin university to continue their further study. After graduation, they can settle down as officials in Daqin.

In this way, only dozens of places need to be paid every year to enable the people of the country to spontaneously learn Chinese. After all, the assessment of the secondary school of the country will not be too strict. As long as they can speak Chinese, it doesn't matter if they can't read. They can teach again in the school.

The third step is the integration of titles, that is, the vassal king has the right to confer the title of minister, but he has to report it afterwards. In the future, if he wants to remove these titles, he must be approved by the Royal Qin Dynasty, and it is not allowed to act first and then act.

The fourth step is military integration.

That is, in the future, the standing forces of each dependent country can not exceed the provisions of the great Qin Dynasty, the military ranks must also be in accordance with the provisions of the great Qin Dynasty, and the standing armies of all countries must accept the recruitment of the great Qin Dynasty unconditionally.

In a few decades or hundreds of years, I'm afraid all the dependent countries will speak Chinese and write Chinese characters, which is not much different from the Han people.

Qin Huan believed that most countries were willing to accept the first step. After all, as long as they came to the great Qin Dynasty to be canonized, their own and national security could be guaranteed, which was definitely a fatal temptation for those small countries.

As for the use of Daqin's treasure money, as long as it can be exchanged for yuan treasure, I believe the people of all countries can also accept it.

Free trade between businessmen of the two countries is a dream of all countries. Private alliances and foreign operations are not allowed. It is too much to ask for instructions, but it is not unacceptable. After all, most countries are peace loving.

As long as the first step is implemented, it will be too late even if the kings do not want to take the next few steps, because at that time, countries already have a sense of belonging to Daqin and do not agree that it is entirely possible to change a person to be a king, and Daqin does not even use force.

It's like boiling a frog in warm water. It assimilates unconsciously. Of course, the premise is that the Central Plains Dynasty should always be stable and strong, and there can be no large-scale civil strife, otherwise everything will stop!

Compared with the barbaric way of colonial plunder in European countries, this suzerain state model of non-interference in other countries' domestic politics and military affairs is absolutely a hundred times more civilized.

The reason why Qin Huan came up with this model of suzerain state was that his eyes were not only on the three-thirds of an acre near the great Qin state.

But in the future, all ethnic groups in the world should become vassal states of Daqin. It doesn't matter if they can't build a country. As long as they accept the canonization of Daqin, Daqin will help you build a country, divide your territory and drive away the invaders.
