In 618 AD, the Tang Dynasty was established and the capital was Chang'an. The Tang Empire became the most powerful empire in East Asia, with a far-reaching prestige and great attraction to Japan and Asian countries.

However, Japan sent envoys to the Sui Dynasty four times, and the government and the opposition admired Chinese culture even more, and there was an upsurge of learning and imitating Chinese culture. In 623 AD, the Sui monks Huiqi and Huiri returned to China after studying in China for many years, and the emperor reported that the Tang Dynasty was the country with the most complete legal system. It was recommended to send envoys to Tang to study.

In order to achieve the goal of learning the advanced system and culture of the Tang Dynasty more directly and effectively, the Japanese government at that time decided to organize a large-scale mission to the Tang Dynasty, send outstanding figures as envoys, and bring overseas students and monks to China.

With the help of the envoys to the Tang Dynasty and the generosity and civilization of the Tang Dynasty, Japan quickly completed the transformation from slavery to feudalism, and also directly took the initiative to learn and use the most advanced skills of the Tang Dynasty, which had a huge impact on the future. For example, in history, after Japan's envoys to China sent to China, they learned the technology of steel filling and 100 steelmaking, and brought Tang knives and other weapons to Japan. However, in China, the development of steelmaking gradually slowed down, and in the later Ming Dynasty, the reason why the Japanese were so difficult to destroy was largely because of the advantages of weapons, so they had the upper hand in the battle against the Ming army.

If it had not been for the steelmaking methods that the Tang envoys had not learned from the Tang Dynasty, Japan would not have been able to develop advanced steelmaking methods. "Learning from Datang" has led to Japan, which has lagged behind for countless years, directly standing on the same starting line as Datang in many aspects.

"I was originally going to hand over to you the people who couldn't enter Chang'an City, so that you could take them to Weinan, so that although they couldn't enter Chang'an City, they could also see the world in Weinan. However, it seems that Wei Qing is not very interested in sending Tang envoys. What's the matter, Wei Qing doesn't know anything about sending Tang envoys? Li Shi saw Wei Renshi's reaction, so he asked.

The Tang delegation was warmly received in the Tang Dynasty at that time.

After receiving the report of the arrival of the mission, the relevant state capital of the Tang Dynasty immediately welcomed them into the pavilion, arranged food and lodging, and played the imperial court at the same time.

The local government sent a special envoy to escort the principal members of the mission who were allowed to enter Beijing to Chang'an, and all the expenses of the journey were borne by the Chinese government.

After sending the Tang envoy to Chang'an, the Tang court envoy led the horse out to greet him, served wine and meat to comfort him, and then got on the horse and the internal envoy introduced the main personnel into the capital, lived in the Sifang Pavilion, and was received by the envoy.

According to the Tang envoy to present tribute, the Tang Emperor issued an edict to commend the Japanese envoys, and gave a banquet in the inner hall, and also awarded knighthoods and rewards to the envoys.

Envoys sent to the Tang Dynasty generally stayed in Chang'an and the interior for about a year, and they could visit and buy books and shop everywhere at will, so as to fully appreciate the customs and customs of the Tang Dynasty.

Before sending the Tang envoys to return to China, there were farewell ceremonies as usual, banquets and drinks, gifts, and cherished farewells.

In the end, the Tang envoy was sent to the coast from the internal envoy to the coast and returned to Japan by boat.

Therefore, Li Shicai thought that Wei Renshi should receive the other personnel of the Tang mission who could not enter Chang'an to meet in Weinan. After all, outside Chang'an City, only Weinan is the most prosperous under the influence of Wei Renshi.

Listening to Li Shi's words, Wei Renshi almost wanted to jump up and give him a kick.

Do you want to make cement?! Do you want the technology of the greenhouse?! Do you want the firing process of glass?! The practice of honeycomb coal is also gone? The technology of coking is not kept secret, or what?!

For a while, Wei Renshi felt that he was going to blow up.

The importance of secrecy that the fuck has been popularizing for you for so long!

Wei Renshi then explained to Li Shi: "Your Majesty, the Wa Kingdom was originally a barbaric and backward barbarian country, and its people were not even as good as the Hui and Tubo people, let alone uneducated. After the former Sui Dynasty, the country was unified, and His Majesty also knew what the grand occasion was during the opening of the emperor's reign. Therefore, at that time, the lord of the Wa State sent four Sui envoys to the former Sui. The people of the Wa Kingdom were not a good thing in the first place, and the reason for sending Sui envoys was not because they wanted to be vassals to the former Sui, nor because of respect. Rather, it serves three purposes. The first purpose is to learn the advanced culture, system, especially technology, and advanced things in all aspects of society in the pre-Sui Dynasty, so as to make a ready-made child, so as to make itself advanced. The second purpose, at that time, Buddhism was introduced to the Wa Kingdom, because the culture of the Wa Kingdom was backward, and there was no ideological system of its own, so after Buddhism arrived in the Wa Kingdom, as a representative of a culture, it had a deep influence on the lords and nobles of the Wa Kingdom, and controlled the slaves with them. In a sense, he has become the ideological master of his country, so he is also seeking Buddhist scriptures. The third purpose is geopolitical factors and profit grabbing. Of these three purposes, the most important is the first, and the second most important is the third. As for the pursuit of Buddhism, it is just an external pretense. ”

"From the time the Tang envoy was sent to the present, if the minister remembers correctly, it has been more than ten times! In the past ten or so times, the Wa Kingdom has already learned all kinds of systems, laws, and craftsman skills that should be learned...... I've learned it all! It took us thousands of years to build up the system, system, law, and technology...... He only sent Tang envoys a few times, and they all went to study! Wei Renshi continued: "At present, the purpose of these envoys to the Tang Dynasty has become to come to the Tang Dynasty to persuade and welcome back those scholars and scholars of the Tang Dynasty who are still living and studying in the Tang Dynasty. Oh - if they know that cement, coking, new wrought iron and steelmaking methods, and new weapons have appeared in our Datang, then they should change their purpose and steal our updated technology! ”

Hearing Wei Renshi's words, Li Shi frowned and asked, "What does Wei Qing mean is that these people will learn the more advanced techniques of my Datang today?!" ”

"Exactly, Your Majesty!" Wei Renshi said to Li Shi: "If Your Majesty doesn't believe it, you can send someone to look through all the previous records of the Tang envoys and look carefully." You will definitely find that after those Tang envoys arrived in the Tang Dynasty, they either wanted to enter the national prison, or they wanted to take the Tang people back to the Japanese Kingdom. Your Majesty went to see the Tang people who returned to the Wa Kingdom with the Sui envoys, and most of them were craftsmen except for the monks! Your Majesty can check the books they took from the Tang Dynasty again, some of them are Buddhist scriptures, and the rest are all of my Tang Dynasty's regulations and legal literature, etc., and the Wa Kingdom is a comprehensive copy of the Tang Dynasty, Your Majesty! ”

Wei Renshi didn't like these envoys.

It is precisely because he collected this information in later generations in order to write papers that Wei Renshi hated them even more.

Look at how Datang treats Japan, and then look at how Japan repays China.

Comparing the two sides, if there are still people who like these Tang envoys, it can only be said that this person is really big-hearted.

Wei Renshi asked himself if he could do it.

From the moment Li Shi heard the three words of sending Tang envoys, Wei Renshi decided.

Take mine and make it up for me!

In short, the plan will not teach them to succeed.

Moreover, they have to pay the price for what they stole from Datang before!
