Especially for Li Xin, he is not ready to eliminate Jiang Zuo now, after all, this piece of meat is too big, and he may be able to get a temporary advantage by rushing into the army, but in the long run, I am afraid that it will be unfavorable after all. Based on these considerations, Li Xin ordered the Tang army to form a new confrontation with the Jin army with the current place of stay as the boundary. Huan Wen also continuously strengthened the defenses along the line, and after returning to Guyi, he began to train a new army, ready to be used to resist the future attack of the Tang Dynasty.

Because the training place is located in Jingkou, it is also called Beifu at this time, so this new army is also called Beifu soldiers!

At the end of May, Li Erhei and Liao Chuan sent news that Pingzhou was finally completely pacified.

Not long ago, the Ministry of Labor received news that Murong Chui and his party had fled to Goguryeo. At that time, Liao Chuan and Li Erhei had already joined forces, captured most of Pingzhou, and were stepping up their march to the surrounding areas to sweep away the remnants of the enemy.

After learning the news, Li Xin sent a secret letter to Liao Chuan and Li Erhei, which contained only a geographical map of mountains and rivers, on which it was written and painted Xuansu, Lelang, Obifang and other counties. Li Xin encircled the peninsula and wrote next to it: "The sea is the boundary!" ”

After seeing this thing, Li Erhei and Liao Chuan and Yu Song all understood what Li Xin meant.

So, a few days later, Li Erhei, Liao Chuan, and Yu Song led an army of 120,000 and attacked the southeast in three ways. At the same time, Goguryeo was severely accused of hiding the remnants of the Yan Kingdom and making enemies of the Tang Dynasty. In addition to strictly ordering them to hand over Murong Ping and the others, they also had to save them from surrendering to the Tang Dynasty.

Faced with the strong pressure of the Tang army, the king of Goguryeo originally planned to surrender, after all, this was not a difficult thing for him, and it was not the first time he had done it. But when he saw Li Xin's conditions, he changed his mind.

Because he wants to take back Xuanxuan, Daifang, Lelang and other places, and appoint officials from the imperial court to take over these places. This means that none of these places will be under his jurisdiction in the future, and he will no longer be able to ~ rule as he did in the past.

This is a little unacceptable for him. After all, although these territories were all picked up by him secretly~ while the Central Plains was in turmoil, it was not so easy to let him hand it over at this time.

In contrast, when he returned to the Yan State and other forces, except for changing his name and lowering his official position, there was no change in power. It's not like under the rule of the Tang Dynasty, he fell from the throne to the position of a real courtier.

Therefore, there is such a gap at this time, coupled with the fact that he believes that today's Goguryeo is far from being comparable to that of the past, and with Murong Ping and others instigating him, this mind is hot.

Xu wanted to disgust the Tang Dynasty, not only did he not hand over the people, but he also gave Murong Ping and others official positions. In this way, he is determined to go against Datang.

Then, he organized a large army and prepared to fight Li Erhei and them hard, so as to protect his throne from being taken away. However, although his ideas are very resolute, his strength cannot support his dreams.

Under the large-scale attack of the Tang army, Goguryeo finally did not support it, and its national capital, Marudu, was officially broken after holding on for ten days. The king of Goguryeo led the remnants of the clan ministers of the kingdom to flee to the south, and finally landed on the island to the east, and it is unknown what the outcome was.

And Li Erhei and Liao Chuan and them advanced by land and water, and killed them all the way from Marudu City to the south. Finally, at the end of July, they made it all the way to the seashore.

In the process of this chase, Murong Ping and the others were also caught one by one. After all, they are no longer of any use to the king of Goguryeo, but have become a burden, why do they stay by his side!

Anyway, after more than four months, the Yan Kingdom was finally completely wiped out. At this point, the Tang Dynasty truly unified the north, and Li Xin immediately set up Daifang, Lelang and other places as Dongzhou, and began to expand to the vast plains in the north while pacifying the people.

The Hu tribes living there, such as Su Shen, Fuyu, Kou Man Khan, and Pi Li, saw that the Tang Dynasty was extremely strong, and they all rushed to Pingzhou to surrender to the Tang army to show their obedience. For these people, in addition to sending envoys to appease them, Li Xin tried his best to ask them to live in the mountains and accept the new policies of the Tang Dynasty.

The demise of the Yan Kingdom made the Tang Dynasty truly remove its worries. At this time, only Datang and Jiangzuo were left in the world, and there was no doubt that Datang had an advantage in terms of territory and population. Moreover, this advantage will definitely become more and more obvious.

Almost everyone believed that Li Xin should soon formally order an attack on the Jiangzuo regime, so as to dominate the world.

Even those people in Jiangzuo almost all think so. Because, Huan Wen worries about this matter almost every day, and constantly deploys troops and horses to guard the border, especially the Yangtze River.

But what people didn't expect was that after unifying the north and eliminating the Yan Kingdom, Li Xin fell uncharacteristically silent, and all the soldiers and horses entered the rest. For the time being, it seems that the soldiers have no intention of fighting again.

At first, Huan Wen and the others thought that Li Xin just wanted to take a break because of the successive battles. But I didn't expect this break, but it was year after year, which greatly exceeded the expectations of people in the world.

After returning to the end of the war, Li Xin began to make every effort to restore the national strength and the production of the people. And the most important thing is naturally to reward the meritorious deeds and reward the soldiers who have made meritorious contributions on the battlefield over the past year or so.

This time, Li Xin sealed the princes and set up the governor's mansion of the five armies. After all, after the establishment of the states, there are generals on the military to deal with, and generals like Li Erhei and them have no need to stay at the border anymore, and they can return to the center.

Li Erhei was named Marquis of Anyuan and appointed as the governor of the Chinese army because of his contribution to the defense of Shuofang and the pacification of Pingzhou and Goguryeo. Zhou Tong was named the Marquis of Xiling and appointed as the governor of the left army for his contribution to the two states of Liang Yi.

Liu Xiaohai with his Pingqingzhou and the destruction of Yan State, promoted to the position of Marquis of Haixing, and served as the governor of the right army. Liao Chuan was appointed as the former military governor for his contribution to the destruction of Goguryeo in Yanding, Pingzhou, and Changchuan. Peng Lin was promoted to the position of Marquis of Gao Yun and appointed as the governor of the rear army because of his outstanding achievements in the Quartet.

These five governors are the leaders of the five military governors' mansions, and they are all second-rank positions, and they have reached the peak of their current positions as civil and military ministers. Although there are still three dukes and three orphans, the title of prince and so on, Li Xin does not plan to put these positions on the actual position.
