After this time, after the gathering in Li's mansion, Hebei Road returned to peace. He recruited troops and trained troops when it was time to help the tribes in the north establish trade channels, and helped them establish trade channels. It can be said that there is no abnormality in the slightest.

The tribes who had surrendered to the Tang Dynasty became more and more convinced by Li Qing after returning. Not only did Tongluo and the Pugu tribe really not suppressed the surrounding small tribes as they promised, but they also tried hard to help them establish business channels with the Tang Dynasty.

After studying with Li Wen, Mou En and Konoha were deeply touched.

They understood that relying on force to control the surrounding tribes like the Uighurs would not last long, but tribes like them were the prey of the weak. Once you really didn't control them, it would not be certain which tribe they had the final say in this territory in a few years.

So under the rules of the game set by Li Yong, they came up with a solution, that is, when the business roads formulated by many tribes to trade with Hebei Road and even Chang'an City, the caravans of other small tribes must pass through the territory of Tongluo or the Pugu tribe.

If they had traded with the Tang Dynasty just for the livelihood of the people in their tribe, Tongluo and the Pugu tribe would naturally not care about it. However, if they had accumulated troops in secret, they would naturally not be able to wait for things to happen.

Li Qing could naturally see what was going on with these little abacuses they made, but he didn't care much about it.

After all, they have their own laws of survival in their territory. Since they are not citizens of the Tang Dynasty, Li Nai naturally cannot use the laws of the Tang Dynasty to demand others, especially when he is just a governor of Hebei Dao.

Li Yi did calm down, but after experiencing the great joy of establishing the queen and crown prince, Chang'an City finally got bad news.

The news was sent by Li Guangbi, who was on Lingnan Road, but the only places involved were not Lingnan Road.

When Li Heng sent Li Guangbi to Lingnan Road, he actually knew that the people of Nanzhao were not very honest. However, since Li Longji had visited Shuzhong before, he was quite familiar with the situation of Jiannan Road, which was also adjacent to Nanzhao.

So Li Heng, in accordance with his old father's advice, sent Li Guangbi directly to Lingnan Road.

Once the Nanzhao people wanted to have any abnormal movement, the Tang Dynasty could at least attack Nanzhao from Jiannan Road and Lingnan Road. After all, compared with Tubo, Nanzhao still did not have much ability. The Tang Dynasty was at least not afraid of the Nanzhao people.

But the heavens are not as good as others. Even when Li Longji returned to Chang'an City, he made arrangements for Jiannan Road and left Li Heng's younger brother, Li Longji's thirteenth son, to take charge.

However, according to Li Guangbi, Cui Yuan, who should be guarding Jiannandao with Li Yu, didn't know when he would go to Guqiu with Nanzhao people, and regarded the south of Jiannandao as the primary target of Nanzhao people. Li Yu was already in a difficult position at this time.

When Li Guangbi wrote a letter to Chang'an City, he was already leading his troops to intercept the Nanzhao people from Lingnan Road to the west, but he still faced the cliché problem, that is, the military strength was really insufficient.

Even if Li Guangbi gave up his defense against Lingnan Road, he could only send about 50,000 troops, which is a huge difference from the forces of the Nanzhao people.

It was said that he was to intercept the Nanzhao people's attack on the southern part of Jiannan Road, but Li Guangbi himself knew that the role he could play was just to slow it down for a while. Neither he nor Li Yu would be able to completely stop the Nanzhao people in the end.

If Jiannan Road is half gone, let alone anything else, if something happens to the Tang Dynasty in the future, the emperor will not even have a big rear. So after learning the news, Li Heng immediately became anxious.

"Sir, you see how to deal with this matter. Although the Nanzhao people occasionally invade our Tang Dynasty, they mostly made small fuss before, and at most they harassed some surrounding villages and people. Even a decent city has never attacked. Why are they so bold and arrogant now?"

Of course, Li Heng immediately found Li Yu and Li Mi, who were already the crown prince, to discuss how to resolve this matter.

The father and son's eyes were all focused on Li Mi. In fact, Li Heng was indeed in a mess at this time, and the emperor was pushed up by his son and his confidants at that time. Basically, there was nothing wrong with him when he encountered something.

Li Yu actually had some thoughts in his mind, but in front of Li Mi and Li Heng, he really had no meaning at all.

The one who controls his father most is his teacher. Even Li Yu knew that if Li Mi had not had Li Mi, his father might not have been able to make such a great determination to be his own.

After Li Mi learned the news, his face was not good either.

In fact, according to Li Mi's own plan, the position of crown prince in the Tang Dynasty was also set, and it was time for him to leave.

When they returned to the mountains where they practiced Taoism, Li Heng and Li Yu had to always support themselves. They had to eat, drink and drink, and they were not short of beautiful girls. This was actually the little life Li Mi wanted to live the most.

But since childhood, Li Heng has definitely treated him well. Now that Li Heng has a difficult time, he certainly can't leave.

However, it is true that Li Wen has a good head, but it is impossible for him to become a good head to appear in the soldiers and horses that Li Guangbi needs most. This is a very typical skillful woman who can't cook without rice.

"Your Majesty, now that Nanzhao has made it clear that he should take advantage of the weak national strength of our Tang Dynasty, it is impossible to escape without any loss. Jiannandao is located in a narrow and long manner. With the strength and ability of the Nanzhao people, it is impossible for them to go too deep. Li Yu's men should be near Yizhou, and Yizhou is the gateway to the north. The people of Nanzhao must not be allowed to break through to this point. Therefore, Your Majesty should inform Li Guangbi and Li Yu that with Quzhou as the boundary, you must not let Nanzhao people pass Quzhou. And south of Quzhou, you may not be able to defend with your current ability!"

"Teacher, there are important towns such as Kunzhou and Yaozhou south of Quzhou. Is this all given to Nanzhao?"

Obviously, Li Yu did not agree with Li Mi's suggestion. The Tang Dynasty belonged to their Li family, so Li Mi could not just say it casually. If you don't want a small half of the Jiannan Dao city, the people will be poisoned by Nanzhao, right?

As the prince, at least Li Yu felt quite unwilling to accept this.
