Li Xiuning was not surprised by what she did, after all, she also knew the threat of these alien races after returning from Liaodong.

But it's too early to know that Datang can wait for five or even ten years.

At that time, Li Xiuning believed that under the leadership of this second brother, he would definitely be able to sweep away the alien races in the north.

At this time, Li Xiuning's thoughts were scattered, and others were not clear, but Li Shimin's eyes kept falling on Shu An.

"I don't know how the Father will choose!"

Li Shimin thought silently, although he didn't say too many words, the meaning was already very clear.

"Actually, winter doesn't seem to be good."

This time, a lot of time has passed, Shu An suddenly chuckled.

If it was before, then Li Shimin hoped that the alien race would not invade in winter, but now Li Shimin is not so different.

As for the reason, then it is the role of cotton clothes, and the soldiers at the border can also eat enough.

Under such a dual situation, there was naturally no more such thing as a soldier losing his life due to the cold in the previous winter.

Even with an adequate supply of food, some elite troops like Xue Rengui still have winter training.

Of course, Xue Rengui can be taught by Shu An, and he is not a stranger to winter training.

Although some people think that Xue Rengui is asking for trouble, the current Xue Rengui has also grown into a big tree by himself, and no one can shake it.

However, the only drawback is that it costs too much, but fortunately, Xue Rengui can directly report to Li Shimin.

If you count it up, Li Shimin can be regarded as the nominal leader of this elite army, and he still has a lot of advantages in terms of cost.

And Li Shimin, who heard his father's words, frowned at first, but then seemed to have some understanding.

The previous emperor didn't think so much, and even in his opinion, it was okay to start a war in any season, or he had confidence.

But now, it seems that winter seems to be really good, and the reason is that the ice and snow in the north will divide the areas one by one.

Those alien races are destined not to be united, after all, in the heavy snow, it is not only difficult to move, but also easy to lose their way.

It is impossible for these aliens to unite, but there is a problem that time seems to be a little rushed.

But if he doesn't attack this winter, then he will have to wait until the next year, which Li Shimin doesn't want to accept.

A year doesn't seem like much, but Li Shimin can't wait, but Li Shimin still doesn't understand where this father's choice is Fangxi.

At this time, Shu An also seemed to see the doubts of this emperor, and the smile on his face remained unchanged, and then slowly spit out a few words.

"Xue Yantuo!"

Even if the former Eastern Turkic Jieli Khan has been depressed in Chang'an, it does not mean that the Turks have perished.

The current Eastern Turkic region was originally led by the leader of Xue Yantuo, Yi Nan, and if this continued, Shu An knew that this Xue Yantuo leader would establish a Xue Yantuo Khanate.

Don't look at the submission to the Tang Dynasty now, but the Turks are like a wolf that can't be fed.

Although the Xue Yantuo Khanate was also destroyed by the Tang Dynasty later, Li Shimin was already in his twilight years at that time.

It also cost Datang a lot of national strength, but it is better to take advantage of the current attack and take the lead in solving Xue Yantuo.

After the words fell, Li Shimin's face first showed a look of surprise, he didn't expect that Yafu would choose the most difficult Xue Yantuo.

Among the alien races in the north, Xue Yantuo is now the real king of the grassland, but because Xue Yantuo surrendered to the Tang Dynasty before.

Therefore, Li Shimin also has a lot of scruples in terms of morality, so he wanted to do something to the Liaodong region before.

didn't expect this father to be more ruthless than him, but he wanted to directly attack Xue Yantuo at this time.

Li Shimin did not speak for the first time, but continued to look at his father, wanting to listen to his explanation.

"The only one in the north who can pose a real threat to Datang is Xue Yantuo."

"There are also many conflicts between Xue Yantuo and the Western Turks, but presumably Xue Yantuo will win."

"At that time, if the leader of Xue Yantuo is ambitious, then uniting the tribes of Hui, Bayegu, Aqiu and other tribes is likely to become a big problem for the Tang Dynasty."

........

This time, Shu An's explanation is very detailed, and any possibility of threat must be strangled in the cradle.

Not to mention that it is recorded in history, Xue Yantuo eventually became a big problem for Datang.

With Shu An's narration, Li Shimin's face also began to become more and more serious, because he had the experience of the previous Turks.

Therefore, if Xue Yantuo truly unifies the entire grassland, then it is really possible to become a threat to the Tang Dynasty in the future.

Even Li Shimin can't sit back and watch something happen, take precautions, if you wait until the future, it will be really too late.

"But if you use a sword against Xue Yantuo, then I'm afraid that this winter may not be able to fully achieve the goal." ‘

But Li Shimin still had some hesitation and said that although the Tang Dynasty in winter can send troops, it will also be affected by ice and snow.

Coupled with the fact that the grassland is so big, if you want to destroy Xue Yantuo, one winter is simply not enough.

If it is to wait until the beginning of spring, then it is very likely that Xue Yantuo will unite other alien races and tribes.

At that time, Datang was afraid that he would be attacked by most of the alien races in the north, and even this emperor had some big heads.

"Now the north is just two places in the grassland and Liaodong, if you do something to the grassland, then let Liaodong be in chaos."

However, in the face of Li Shimin's questioning, how could Shu An not think about this question, and quickly responded.

"Let Liaodong be in chaos?"

Li Shimin was stunned and said, but then felt that this matter was not easy.

"The people of the world must have seen the messenger of Silla, but I don't know what they think?"

Shu An's voice continued to sound, knowing that this matter has a lot to do with these small countries.

"Really?"

Li Shimin suddenly remembered something and said softly, there is a lot of research on the emperor of the countries around the Tang Dynasty.

In other words, when there is nothing to spare, this emperor will study it, and he will naturally understand the contradiction between Silla and Goguryeo.

Similarly, Goguryeo is also the main threat to Liaodong in the Tang Dynasty, but if you want Silla to start a war against Goguryeo, this is possible, you must know that Silla has been pressed and beaten.

Otherwise, he would not have sent an envoy to Datang, just to seek Datang's support.

However, if you pay a certain price, then it seems that it is not an impossible thing, once these two small countries start a war, then Liaodong will be chaotic.
