"Look at it, this is the latest information sent by the north!" After discussing the matter of the academy, Li Shimin handed a memorial to Li Xiu and Changsun Wuji and said, with a look of worry on his face. .

At that moment, Changsun Wuji took the memorial and looked at it first, but a solemn expression appeared on his face, and then handed it to Li Xiu. As a result, when Li Xiu opened the memorial, he also frowned, because this was a piece of information about the latest developments in the northern grasslands, and the movements of the main forces on the grasslands were described, and the longest part was about Xue Yantuo's movements.

In early March, the eldest son of Xueyantuo Khan Yinan raised troops south and destroyed the Hutu tribe, which was entrenched in the south of the desert. In the middle of the year, Yinan's second son sent troops to fight eastward and annexed another tribe, Donghe tribe. In April, Xueyantuo Khan Yinan personally sent troops to fight with the Uighurs for three days, and both sides had their own victory and defeat...

Li Xiu also felt very difficult when he looked at the information in his hand. He did not expect that even under the suppression of the Tang Dynasty, Xue Yantuo could develop so quickly. Now he has become the overlord on the northern grassland of the Mobei Province and has even begun to extend his power to the south of the Mobei Province. If they continue to develop like this, they may be bounded with the land of the Tang Dynasty further south. At that time, the people on the border of the Tang Dynasty will suffer from wars again.

"What do you think about this?" Li Shimin saw that Li Xiu and Changsun Wuji had read this information and asked immediately. Although the Turks were destroyed and the remaining Turks were moved to the south to open up land and farm, the Hu people on the grassland were killed indefinitely. The Tang Dynasty did not have the energy to completely occupy the entire grassland, so he could only pay attention to the trends of the grassland at all times to avoid another Turk.

"We must have to curb Xue Yantuo's expansion, but now I am worried that our previous method of curbing Xue Yantuo may have failed. To stop Xue Yantuo's expansion momentum, we must come up with a more effective way!" Changsun Wuji spoke almost without hesitation at this time.

When the Turks were destroyed, Xue Yantuo had tested the attitude of the Tang Dynasty, but almost dragged the victorious army to death on the grassland. Li Shimin was furious and not only suppressed Xue Yantuo everywhere on the surface, but also secretly provoked Xue Yantuo's internal or peripheral tribes, causing Xue Yantuo to fall into internal and external troubles.

However, this method only lasted for several years. Xueyantuo Khan Yi Nan was also a powerful figure. He first cleared out some internal opposition forces, and then gathered the power of the entire tribe to expand outward. In recent years, the power has been at its peak. Except for a few large tribes such as the Uighurs, there has been no longer any force to pinch their power on the grassland.

"I am also considering this issue now, but Xue Yantuo is mainly entrenched in the northern part of the world. If we work hard to expedition, we will not talk about how much manpower and material resources we need to consume, and we are not sure of winning. But if we don't send troops, there is no way to weaken Xue Yantuo's strength." Li Shimin also said very distressedly at this time.

"We definitely cannot send troops. After all, from the Tang Dynasty to the north of Mobei, and the grassland climate is unpredictable, no one knows what to encounter. The long expedition of the army has always been a taboo in military strategists, so I think it is best to let other forces fight with Xue Yantuo. For example, the Uighurs is a good choice. They have always had good friends with our Tang Dynasty and have conflicts with Xue Yantuo. Their strength is not much worse than Xue Yantuo. As long as they join forces with a few tribes, they should be able to compete with Xue Yantuo for a long time." Changsun Wuji thought about it for a moment and spoke.

"The Uighurs are indeed a choice, but the Uighurs are not stupid. They will never be willing to work hard for us. If you want to persuade them, you may have to pay a considerable price. In addition, I am also worried that killing Xue Yantuo will make the Uighurs a big deal in the future!" Li Shimin said distressed again at this time. As an emperor, he must consider all aspects of things and often face a dilemma, and he can only choose a solution with the least harm in the end.

When Li Shimin said this, he suddenly realized that Li Xiu had not spoken, but instead looked at the memorial just now, but his eyes seemed a little distracted, as if he was in deep thought, which made Li Shimin unable to help but ask, "Li Xiu, what do you think about this matter?"

Hearing Li Shimin's words, Li Xiu seemed to wake up from his thoughts. He looked up at Li Shimin and Changsun Wuji, and then pointed to a passage in the memorial and said: "Your Majesty, I found that in March, Yi Nan sent two sons to fight in the east. Could it be that he had already divided the power of military power to his two sons?"

"Yes, Yi Nan's two sons have grown up long ago. In addition, Xue Yantuo had civil strife before. In order to control power, Yi Nan handed over part of the military power in the tribe to his two sons. In this way, the father and son will control most of the military power in the tribe, and no soldiers can be used for others if they want to rebel!" Li Shimin nodded immediately and said.

"Haha, it seems that Yi Nan really doesn't have a good memory. If Your Majesty wants to deal with him, there is actually no need to spend any effort to buy the Uighurs." Li Xiu suddenly smiled relaxed when he heard this.

"Oh? What's your solution?" Li Shimin couldn't help but feel shocked when he heard Li Xiu's words and asked immediately.

"Your Majesty still remember how you divided the various forces on the grassland when Jie Li was in great power?" Li Xiu did not answer immediately, but instead smiled and spoke again.

"At the beginning?" Li Shimin couldn't help but show a contemplative expression when he heard Li Xiu's words. When Jie Li was in great power, he did use many means to differentiate the forces on the grassland, but many years have passed, and Jie Li had already died, so he really couldn't think of the things he did at the time?

"Haha, my son-in-law, I know how to deal with Xue Yantuo!" Changsun Wuji's memory was obviously much better than Li Shimin. He immediately reacted when he heard Li Xiu's words, and a relaxed smile appeared on his face.

"Don't keep it a secret for you two. Tell me quickly how to deal with Xue Yantuo." Li Shimin understood when he saw that the company commander Sun Wuji understood, and he couldn't help but ask anxiously.
