As for Guo Ziyi's side, Li Qing knew that he didn't have to worry about it. He had been fighting on the battlefield for so many years, so he naturally had his own way to escape.

When the group arrived in Yizhou, Li Yu was so excited. Although Li Yong's early preparations were good, when he heard that the Tubo people sent 300,000 troops directly, he was still scared. He didn't know if Li Yong could withstand it.

If Li Qing couldn't resist it, what would he do with the prince had always been a matter of confusion in Li Yu. Because he had no soldiers in his hands, he could only run away once the enemy attacked him.

Now, it doesn’t matter what method is used. What’s important is that Li Yan really lets the Tubo people retreat.

"Third brother, this time, you really saved the Tang Dynasty!"

In front of the Jiannan Dao ministers and generals, Li Yu expressed his true feelings. As soon as he said this, he basically declared that all the contributions this time were from Li.

"Crown Prince, I'm lucky to be a blessing to be aware of my fate. If the prince had not been in charge of Yizhou, I'm afraid the soldiers would not be able to use their lives like this!"

The two brothers praised each other for a few words, and then went to the city. In Yizhou, Li Yu had prepared a sumptuous banquet for Li Yan to welcome his triumphant brother.

During the banquet, Li Yi directly proposed that the Tang Dynasty, represented by Li Yu, the crown prince, signed an alliance with Nanzhao, who made great contributions in the battle against the Tubo people. In dealing with Tubo, the Tang Dynasty and Nanzhao would form an offensive and defensive alliance.

Regarding Li Qing's proposal, at the beginning, Li Yu wanted to write a letter to ask Li Heng for instructions, but when he saw that Ge Luofeng had already come with Li Qing, he heard about Li Qing's daughter Feng Yi during the meal that after Li Qing returned to Chang'an City, he would marry Ge Luofeng's daughter Feng Yi, so Li Yu did not hesitate this time and directly agreed to the matter.

The next morning, Li Yu summoned all officials in Yizhou City and signed an alliance with Nanzhao King Ge Luofeng in front of everyone in the name of the crown prince of the Tang Dynasty. The provisions in this alliance were very clear that whether it was the Tang Dynasty or Nanzhao, as long as one side was attacked by the Tubo people, the other side must also send all its troops.

In addition, the trade exchanges between Nanzhao and the Tang Dynasty were strengthened, and a little bit of a hole was made for them in terms of salt and iron.

This is a treatment that no other tribe does not have. Ge Luofeng actually knew in his heart that these benefits were all because of Li Qing and Feng Yi. Nanzhao wanted to go further after unifying the Six Divines, which was in this era.

After the signing of the alliance, Ge Luofeng immediately resigned with Li Neng and Li Yu, and took his generals to go back to Taihe City.

After all, although the Tubo people are now retreating, when they find that their royal city is fine, they are still very likely to throw their anger at Nanzhao.

After Ge Luofeng left, Li Yu asked Li Qing to explain in detail how Chi Song Dezan retreated.

When Li Yu said that he borrowed Guo Ziyi's troops and took a very high risk to surround Wei and rescue Zhao in Tubo's nest, Li Yu could not say a word for a long time.

Li Yu thought Li Yu would not expect that he would be so brave, but the real situation was that Li Yu never wanted it. As a rank of officials of the Tang Dynasty and could almost be said to be the oldest general in the Tang Dynasty, he would have completely obeyed Li Yu under such circumstances.

Of course he knew that Li Yi had not contacted Guo Ziyi directly through himself or Li Heng under such circumstances, and it was definitely urgent to be in power, but what made him even more concerned was that Guo Ziyi actually listened to Li Yi directly.

Even Guo Ziyi is like this, let alone other generals of the Tang Dynasty.

In other words, from this incident, we can see that the mobilization of most of the soldiers and horses in the Tang Dynasty was almost the same as Li Qing. If Li Heng said, Li Qing has almost become Li Shimin of the past.

Li Yu suddenly felt that the title of Prince is probably meaningless to him. If Li Wen can always put himself first in everything like he is now, he would be able to maintain it. However, if Li Wen gets upset one day and doesn't want to maintain it, it's not the prince who can decide.

From this moment on, Li Yu became a little absent-minded, and Li Yi could indeed feel it, but he did not investigate the reason in it in depth.

After Ge Luofeng left Yizhou, Li Neng re-arranged the defense of Jiannan Road again. Because there were no talents who could fight in Jiannan Road that could be proved, Li Neng could only regard Jiannan Road and Lingnan Road as a whole. The guards of these two places were all handed over to the 50,000 or 60,000 people he brought with him.

Although he knew that this was a very difficult task, Li Guangbi also understood what the situation was in the Tang Dynasty now, and now the Tang Dynasty and Nanzhao have signed an alliance. If something really happened, his troops and the people under Ge Luofeng could withstand it for a long time.

Just as everything in Jiannan Road was almost done, Li Yu and Li Qing were about to take a rest for another two days before returning to Chang'an City, they sent a message of expediting thousands of miles from Chang'an City.

When Li Yu saw the letter he sent, his face turned pale. He dismissed everyone out, leaving only him and Li Neng in the house, and then handed the letter to Li Neng tremblingly.

Seeing that Li Yu suddenly became like this, Li Yi felt aroused, as if he had thought of something, but his expression had not changed much, so he took the letter directly.

However, when Li Yi really saw the contents of the letter, his face couldn't help but change.

The letter was written by several prime ministers in a joint name, and the contents were very short, that is, the emperor and the emperor were sick recently. Since the two of them had temporarily repelled the Tubo people, they should go back to the court quickly. If they go back late, something might happen.

Although this is very obscure, Li Yu and Li Qing can see what it means. Obviously, Li Heng and Li Longji fell ill at the same time, and judging from this posture, it is obviously a big deal.
