The Battle of Goryeo took less than a few days to end.

In other words, there are more than five vassal states under the Tang Dynasty's court with a population of one million, including the Bohai Kingdom, the Goryeo Kingdom, the Wuyue Kingdom, the Dali Kingdom, and the Zhenla Kingdom. The sphere of influence, from the Northeast to South Asia.

In addition to nominal interests, the merchants of the Tang Kingdom could also conduct business activities in their countries without any obstacles. Shaofu Temple and Maritime Affairs Office made a big profit.

The Silk Road has formed a practical route.

Zhenla, Chameng, Guangzhou, Quanzhou, Hangzhou, Jinshan, Jeju, Kaijing, Anbian Prefecture, and finally Longquan Prefecture, the capital of the Bohai Kingdom.

The market spans tens of thousands of miles is extremely vast.

It can be imagined that on this golden route, merchant ships were weaving, thousands of sails competed for their success, and the Tang ship carrying silk, paper, books, spices, porcelain, ivory, agate, tortoiseshell and other commodities told the power of the Tang Dynasty to all parts of the world.

Isn't this more majestic and quicker than Zheng He's voyage to the West?

"There are five great countries, and the Tang Dynasty is already a great country in the world. I wonder how the Zhengshitang deals with this vassal state?"

Li Jia shook her head, disregarded Sun Zhao's words, and then turned her head to Zhao Cheng and said.

"During the Tang Dynasty, there were two types of vassal states. One was the internal vassal state, the Beiting Protectorate, the Heishui Protectorate and other internal vassal states. For example, the Western Regions countries must pay tribute every year, and the Protector leads his troops and takes the protons in Chang'an.

As for the countries that are transformed into foreign countries, they are all granted kings and set as bans. They are also divided into three or nine levels, such as Silla, Tubo, Dashi, Uighurs, etc., which are the first level and are given six lunar eclipse, and the others are reduced in turn..."

Zhao Cheng said casually.

Hearing this, Li Jia nodded, sat down slowly, and thought carefully.

The Tang Dynasty's tribute system was the culmination of China. The title of Tian Khan almost topped the Tang Dynasty and had the right to deal with the countries in the world.

The internal vassal states, which are basically semi-autonomous, need to be recognized by the court in order to hold the throne. By the time of Emperor Xuanzong of Tang, the number of people tributed by various countries each year exceeded 4,000.

Honglu Temple was so worried.

Foreign vassals, such as the newly conquered Goryeo, basically only offer the goods and give them back equally, hoping that the two countries will be at peace and equal.

As for Li Jia's request for 50,000 jin of money and 50,000 jin of grain, it really hurt the face of the Supreme Kingdom of the Celestial Empire. The prime ministers did not say it on the surface, but they were muttering in their hearts.

Today, I am indeed a greedy person!

"The internal vassal state is already considered good. Protons and other measures are very good, but for foreign vassal states, it is not possible, and it is on the surface."

Li Jia murmured softly, and thought of the tribute system in the Ming and Qing dynasties. Ming Taizu included vassal states in the monogenic system with China as the core, especially his right to enthronement. Without China's enthronement, the king could hardly hold the throne.

However, during the Tang Dynasty, whether there were enthronements or not was of little effect.

Then, the tribute system began to expand. At the same time, Japan also put forward tribute requirements for Ryukyu and North Korea, North Korea to Jurchens, Vietnam to Champa, Nanzhang and other countries, forming several secondary tribute centers.

This is equivalent to that if the Ming Dynasty had the intention, its influence could actually cover most of Asia.

Tribute during the Ming and Qing dynasties stipulated the obligations of vassal states, such as pilgrimage and tribute. China also had the obligation to protect vassal states, which was mutual.

For example, the Ming Dynasty sent troops to Korea, the Qing Dynasty due to the Sino-French War in Vietnam, and the Sino-Japanese War in Korea were the last aftermath of the tribute system.

"The jurisdiction of foreign vassal states is still a bit rough!"

Li Jia felt a clear mind and said in a deep voice.

"I am vulgar, I hope your Majesty will tell you!"

Several prime ministers said respectfully.

Although the Zhengshitang pursues vassal states, it still cannot reach the emperor.

After all, the title of Tian Khan greatly satisfyed the emperor's vanity. Every emperor had Tian Khan's dream, especially after the Anshi Rebellion, when internal and external difficulties were in trouble, it became the emperor's heart.

The prime ministers didn't care about these things and let the emperor deal with them. Anyway, they would not affect the country, and their impact on them was even more slim.

Under the indulgence of the prime ministers, Li Jia was extremely happy. He used his excitement to express his vanity as a time traveler:

"The Tang Dynasty is the lord of the Tang Dynasty, and naturally the lord of the world."

"In my opinion, the etiquette and respectful follower of the country are different, and should be divided into different levels to evaluate their countries and pay tribute and rewards, which are naturally different."

The central meaning of this sentence is that the world is the world. Although all countries pay tribute to me, their customs, population size and degree of obedience are different, so they divide the levels and formulate their due powers and obligations.

"Therefore, the country has a second-class and the first-class are princes, such as Goryeo, Wu and Yue. Their people exceed one million, their place is thousands of miles away, and their armored soldiers exceed ten thousand. It is natural that they should be princes. They must pay tribute every year, and the number will be determined!"

Li Jia said softly, and then said that from today on, the Dali Kingdom and the Zhenla Kingdom must also pay some tribute, not those lions and tigers, but real gold and silver, such as grain, copper, gold and silver, cloth, etc., and no one is exceptional.

Of course, they had to send the crown prince to Changsha and go to the Imperial College for study, and they were not released until they became an adult.

Instead, it is necessary to cooperate with the Tang Dynasty's war. If necessary, a large army must be sent to cooperate.

Paying tribute, protons, and supporting military forces are the obligations of first-class vassal states.

As for the Tang Dynasty's obligation, it was to ensure that it was not invaded by other countries, subvert the regime, and ensure the security of its country.

The most important thing is that if there was no enthronement of the Tang Dynasty, the king of the country would not be orthodox, would no longer protect his safety, and would even go to conquer.

As for vassal states, they are called Xiao Wang, and are comparable to Dukes. For example, some small countries, the Tang Dynasty did not bother to ask for too much. As long as they accepted the canonization, came to pay tribute every year, and gave them equivalents.

This is equivalent to the attitude of foreign vassal states in the pre-Tang Dynasty.

"All vassal citizens can come to the Tang Dynasty to do business, study, serve as soldiers, and even participate in the imperial examination!"

Li Jia finished speaking in one breath and was quite excited.

This was re-edited by him based on the tribute system of the Tang Dynasty and the Ming and Qing Dynasties. It can be said that his jurisdiction over the vassal states has greatly increased.

If it is according to Western standards, this can be considered a country.

After saying that, he looked at the prime ministers and waited for praise.
