The Tang Dynasty does not know much about the Wa Kingdom, and only part of the information can be found in history, and the nearest one has been almost twenty years, and since then, the two countries have not interacted with each other.

The main reason is due to the chaotic times at the end of the Sui Dynasty and the lack of care about others at the beginning of the Tang Dynasty.

However, compared with the Wa Kingdom, the Tang Dynasty has a lot more understanding of Goguryeo, and the two countries have been constantly communicating in recent years.

In the fifth year of Wude, Li Yuan was grateful to the Han soldiers who died in Goguryeo at the end of the Sui Dynasty due to the Gongda Goguryeo, so he personally wrote a letter, agreeing that Goguryeo would send these Han people who stayed in Goguryeo for some reason back to China, and at the same time, Li Yuan also ordered the Tang Dynasty to send back the Goguryeo people who stayed in the Tang Dynasty for some reason.

And Gao Jianwu did not work hard this time, and did his best to search for the outlaws of the country, and escorted them back to China with the gift of guests, nearly 10,000 people before and after.

And Gao Jianwu also won the favor of Li Yuan and the Tang Dynasty, so he had seven years of martial arts, Li Yuan sent Shen Shu'an, the secretary of the Criminal Department, to Goguryeo, and canonized Gao Jianwu as the Shangzhu State, the king of Liaodong County, and the king of Goguryeo.

This is equivalent to adding the hardest insurance to Gao Jianwu, at this time, no matter how much anyone dares to oppose him in the country, or raise troops to rebel or something, what he needs to worry about is not Gao Jianwu's counterattack alone, at least he has to think about it first, they can't provoke the Tang Dynasty.

Gao Jianwu used several years of hard work, pretending to be a grandson as a dog, and finally won the approval of Datang, and then his fangs were revealed.

In the ninth year of Mudeok, Silla and Baekje wrote to Lee Yuan, saying that Gao Jianwu had closed the road so that he could not enter the Hajj and had repeatedly harassed them.

According to the records of the secret scroll, this matter actually started a long time ago, but it was only in the ninth year of Wude that this letter was sent to Chang'an, and as for the previous one, of course, it was stopped.

Li Yuan was furious when he heard this, and the edict ordered Zhu Zihao, a waiter to go to mediate, and Gao Jianwu apologized and asked for reconciliation between the two countries.

Then there is the recent news, this year's Tang Dynasty's destruction of the Turks, which also brought a great shock to Goguryeo, Gao Jianwu hurriedly sent a messenger to congratulate the Tang Dynasty and presented the map of the domain.

The envoy of Goguryeo probably left Chang'an in October, but before leaving, his envoy also inquired about the news that the king of Zhao of the Tang Dynasty was going to inspect the kingdoms of Liaodong in the future.

"Are you all going with this king?" Li Yuanjing was a little surprised, these goods have a good life, but go out with yourself?

"That's right, Your Highness, we are also brothers who have suffered together, you can't just think about Fang Er with this kind of good thing!" Cheng Chuliang was chattering and dissatisfied.

His eldest brother definitely can't go, Li Yuanjing has already arranged a lot of work for him, but Cheng Chuliang is a little bit small in his heart.

Being beaten at home all day, you have to be careful outside, and you finally have such a chance to go to the vassal country to be powerful, so a fool won't go.

So a few people discussed, let's just block the door......

"Have you read all this?" Li Yuanjing was a little speechless, but it was not good to refuse directly.

"I've seen it, some of it was still found by us, Gao Jianwu is docile like the local dog outside the village, I feel excited when I think about it......" Cheng Chuliang smirked.

Docile?

Li Yuanjing smiled, if a scheming person like Gao Jianwu was docile, then he really didn't know what to say.

Judging from the data, this is true, but why did Gao Jianwu block the road and prevent Silla and Baekje from entering the Hajj?

Why did Li Yuan send Zhu Zihao, who was not a high official position, to mediate, and Gao Jianwu, who was frightened, hurriedly wrote a letter to ask for peace?

No one is a fool, and no one will think that Gao Jianwu is docile, and it is estimated that it is just these fools in front of him.

Even Gao Jianwu couldn't see that he was testing the Tang Dynasty, if Li Yuan didn't react to this back then, it is estimated that it would be a huge question mark whether Silla and Baekje still exist now!

"When you go out, you may encounter some unexpected dangers, you better think clearly before deciding!" Li Yuanjing didn't tell them some details of their speculation, but just left the decision to them to solve.

"Think clearly, you must go, who knows when the next time will be!" The eldest grandson rubbed his hands eagerly, with a look on his face.

Young men in their teens, youth hormones are at a vigorous age, and Fang Er's goods have already blown this trip to Goguryeo in front of them, can these goods still bear it?

"Go find a thousand-stone sea ship yourself, you can prepare a shipload of goods to accompany you, and this king will let you make a windfall." Li Yuanjing nodded and didn't say anything more.

"Hehe, it's been prepared for a long time, His Royal Highness has prepared all kinds of cloth, I discussed it with Fang Er, get a boatload of porcelain, and Changsun Jian has prepared a boatload of tea, and you can set off in half a month!" Cheng Chuliang said with a sly smile.

"Okay, the fifteenth day of the first lunar month will depart from Chang'an!" Li Yuanjing was speechless, these goods are really attentive, and even the goods are ready.

He rowed for a few months before, but only collected twelve thousand-stone sea ships, cloth or something is very simple, just pull it directly from the Yangzhou workshop, and Yangzhou is also a rich production area of silk, Li Yuanjing directly purchased a batch of silk of various grades over there, and it happened to be loaded nearby.

Of course, another reason for choosing to go to sea from the south of the Yangtze River was mainly because the 2,000 sailors given to him by Li Shimin were trained there.

As for the quality of the navy, this Li Yuanjing is not clear for the time being, anyway, he doesn't have too high expectations, just don't get seasick.

Next, on the eve of the New Year's Day, Li Yuanjing got the edict given to him by the imperial court, and in a blink of an eye, Li Yuanjing changed from a private trip to an official trip.

However, Li Yuanjing didn't care about this, but Li Shimin arranged two supervising imperial histories by his side, which made Li Yuanjing feel a little uncomfortable in his heart. Will they say that you are not decent enough or something?

It wasn't until after the end of the Zhengdan Dynasty meeting that Li Shimin asked people to call Li Yuanjing over.

He replied shyly and reminded Gao Jianwu that it was not so simple, and he should pay more attention to everything, and then he asked Li Yuanjing to pay homage to the soldiers who died in the Sui Dynasty for him after he arrived in Goguryeo.

Li Shimin wanted to harvest his prestige crazily, but it turned out that it was Li Yuanjing who ran errands, and Li Yuanjing only nodded and agreed, this trip was not just as simple as having fun.
