Li Shimin was on the way back when he received Ashina Simo's recital. After reading the recital, Li Shimin was silent for a long time, and then he closed the recital, walked out of the room alone, looked up at the moon, and was dumbfounded.

After the Turkic matter was settled, Li Shimin thought that he would be able to stop for at least a few months. But I didn't expect trouble to come so soon.

Xue Yantuo!

After walking a Turk, another Xue Yantuo came.

Xue Yantuo, originally one of the Tiele tribes, by the merger of Xue and Yantuo, the ancestors of Xue Yantuo had lived together with the tribe surnamed "Xue", and later annexed the tribe called "Yantuo", so it was called "Xue Yantuo", the official system and customs, and the Turks were about the same.

During the great cause of Emperor Yang of the Sui Dynasty, the Eastern Turks were powerful, and the Tiele tribes living in Mobei belonged to it. At that time, the Eastern Turks Luo Khan levied taxes excessively, and the Tiele tribes complained, and when the Luo heard these complaints, he was furious and killed more than 100 Tiele chieftains. The Tiele tribes then rebelled by force, and jointly promoted the leader of the Khambi as the Khan of Yi Mozhen Mohe, and the leader of Xue Yantuo, Yi Lost Bowl, as the Khan of Yi Yu, and turned against the Western Turks and was hostile to the Eastern Turks.

When Li Shimin had just sat on the throne of the emperor, the Western Turks were in civil strife and fled. The leader of Xue Yantuo, Yi Nan, led more than 70,000 households of his tribe to submit to the Eastern Turks again, and he expected the Khan of the Eastern Turks to change from Chuluo to Jieli, but he never expected Jieli to be a more brutal person than Chuluo. Yi Nan had no choice but to lead his subordinates to resist hard, and Jieli sent an army to suppress it, but he didn't expect to be defeated by Yi Nan, and even incorporated many Turkic tribes.

The victory in this battle completely changed the attitude of the Tiele people towards the Turks. For the first time, they felt that the seemingly invincible Turks could actually be defeated. In the winter of that year, the surnames of Tiele elected the great hero of Tiele to become the Khan. Yi Nan didn't dare to admit it, and insisted on not accepting it.

At that time, Li Shimin was preparing for the use of troops against the Eastern Turks, uniting all the forces that could be united, and trying to weaken the Eastern Turks. The ministers discussed, and they all believed that they would unite Xue Yantuo, create trouble for the Eastern Turks, involve their troops, and echo the interests of the Tang Dynasty. So Li Shimin sent the guerrilla general Qiao Shiwang to secretly contact Yinan, and worshiped Yinan as the pearl Viga Khan, and rewarded him with a lot of treasures. Yi Nan was overjoyed, so he agreed to take over the throne of the Great Khan, established the Xue Yantuo Khanate, built a tooth at the foot of the desert Yu Overseer Mountain, and fought against the Eastern Turks, because he accepted Li Shimin's canonization, Xue Yantuo naturally became a vassal state of the Tang Dynasty in Mobei.

After the establishment of the Xue Yantuo Khanate, a small number of nomadic tribes who had been humiliated by the Eastern and Western Turks, such as the Hui Hui, Bayegu, Aqiu, Tongluo, Fugu, Xia, etc., were annexed one after another, and Xue Yantuo's territory became larger and larger, with a population of more than 400,000 and 50,000 elite soldiers.

With the expansion of his strength, Xue Yantuo's actions became more and more unscrupulous. The attitude towards the Eastern Turks became more and more tough, and even made many sneak attacks with troops. And his attitude towards Datang has also become arrogant with the improvement of his own ability. Li Shimin took into account the overall situation of exterminating the Eastern Turks, and did not stop or punish it, but added more rewards, which made Yi Nan have the illusion that Xue Yantuo was of great importance to the Tang Dynasty.

When the Tang destroyed the Eastern Turks, a large number of defeated Turkic tribes were left homeless. They were unwilling to attach to the Tang Dynasty, let alone join the Western Turks, so they could only go north to join Xue Yantuo. Moreover, after the war, Li Shimin placed the remnants of the Eastern Turks in the Hetao area, so that the East Turks were also important and the Shuosai region was empty, Xue Yantuo took the opportunity to rapidly expand his power, occupied most of the territory of the original Eastern Turks, and moved the tooth tent from Yu Dujun Mountain to the south of the Duluo River in the north of Duwei Jieshan, which was closer to the border of the Tang Dynasty.

At this time, Xue Yantuo's heart of disobedience appeared. The envoys of the Tang Dynasty are not as respectful as before. There are often contemptuous behaviors, and I don't care about them.

A large part of the reason why Ashina Simo was able to agree to the attachment so readily was also because of Xue Yantuo. Xue Yantuo is getting stronger and stronger, and they also covet the fertile pastures of the Hetao, but this grassland was originally Turkic, even if it is not counted, in the past, when the Eastern and Western Turks were not divided, this was where the royal court of the people was located, which could not be relied on. Xue Yantuo wanted to grab this grassland, so he had to fight.

In recent months, friction has been common. The Turkic side did not win once, but Li Xiaogong and Li Ji's army approached, Xue Yantuo relented a lot, and the men and horses withdrew to the other side of the river, without a head-on conflict with the Tang army.

After attached, this group of Turks is the real people of the Tang Dynasty, and if Xue Yantuo dares to harass again, it will be equivalent to a war with the Tang Dynasty. Although Xue Yantuo is strong, it is only relative to the current weak Eastern Turks, and against the Tang Dynasty, Ashina Simo still firmly believes that the Tang Dynasty will definitely win.

This is Ashina Simo's perspective on things, but for Li Shimin, he doesn't think about this.

In fact, as an opponent, Li Shimin has never taken Xue Yantuo in his eyes. Don't look at how many elite soldiers Xue Yantuo has now, in Li Shimin's eyes, he is just a local chicken and a dog, and it is not worth mentioning at all.

The reason is simple. Xue Yantuo is a typical tribal state, and the ethnic composition is very complex. It swells too fast, its personnel are uneven, and if the war goes smoothly and the army roars by, there is no problem to be seen, and once it encounters hard stubble, the war is scorched, and this loose tribal country will soon fall apart.

If he fights, Li Shimin doesn't need to think about it at all, the 20,000 people led by Li Ji will be enough to overturn Xue Yantuo's 100,000 people. Li Shimin is not afraid of fighting, but what he is afraid of is that it will involve energy.

Whether it is Li Xiaogong or Li Ji, it is Li Shimin who is ready to use it to fight Goguryeo's people. In Li Shimin's eyes, only Goguryeo can be regarded as an opponent. If you fight with Xue Yantuo at this time, you will inevitably have to divide at least 20,000 people to fight with Xue Yantuo, and Xue Yantuo's territory is so big, if Yi Nan wants to delay, it will be too easy to drag it for a year and a half. If we want to use troops against Goguryeo next year, there will be a shortage of 20,000 people, which may affect whether the war can be won or not.

Li Shimin regarded the war against Goguryeo as the last and most glorious battle of his life, and he would not let Xue Yantuo ruin his hard-won victory.

This was one of them, at that time, Li Shimin was preparing for the use of troops against the Eastern Turks, uniting all the forces that could be united, and trying to weaken the Eastern Turks.
