Xue Yantuo's Zhenzhu Khan Yinan tried to bite off a piece of fat from the Tang Dynasty, but Tang Taizong ordered Li Shichang, Zhang Jian, Li Daliang, Zhang Shigui, Li Xiyu and others to send more than 100,000 troops, starting from Yingzhou in the east and Liangzhou in the west, and Wudao sent troops to counterattack Xue Yantuo.

Xue Yantuo crossed the desert and marched thousands of miles, the men and horses were tired, and the Turks burned and cut the autumn grass, causing the horses to gnaw the branches and skins of the forest.

In December, Dadu set up 30,000 cavalry to force the Great Wall, Li Shiyun led the Tang soldiers to, the dust rose to the sky, and Dadu set up fear and went north.

Li Shiyun selected 6,000 cavalry and Turkic elite cavalry under his subordinates, chased through Baidaochuan to Nuozhenshui, and the two sides fought fiercely.

Xue Yantuo's arrows were fired together, Tang Zhan Ma died, Shi Xun ordered the soldiers to dismount and rush to the enemy formation, Xue Yantuo's troops were defeated, and the Tang soldiers attacked, beheading more than 3,000 people and capturing more than 50,000 people.

The remnants of the Dadu set up the rate to run to the north of the desert, and it was snowing heavily, and Xue Yantuo froze to death eight or nine times out of ten.

Yi Nan was afraid that Datang would launch a retaliatory devastating blow against him, so he hurriedly asked people to go to Chang'an, the capital of Datang, with heavy gifts, to apologize, and at the same time proposed to Datang that he wanted to marry a princess.

The Zhenzhu Khan Yinan in the Xue Yantuo Department thought that as long as he sincerely admitted defeat and expressed his submission to the Tang Dynasty, the Tang Emperor would not refuse his marriage proposal in order to appease himself.

At that time, Ashina Simo, followed Jieli Khan, was loyal to Jieli Khan, and finally together with Jieli Khan, was captured alive by the Tang Dynasty, and was escorted to Chang'an, in order to appease Ashina Simo, Tang Emperor Li Shimin, didn't he also marry an eldest princess to Ashina Simo?

And also reused him, made him the new Eastern Turk Khan, and let him take the original people back to the hometown of the Eastern Turks, living on the Monan steppe, and allowed them to enter Shuofang in Tang City to spend the winter when the harsh winter comes.

There is also Tuyuhun, how strong he was before, repeatedly violated the Tang Dynasty, which made the Tang Dynasty angry, sent troops to defeat Tuyuhun, and finally raised another Tuyuhun king, and married a princess to the Tuyuhun king.

Although Tubo was finally destroyed by the Subi State, but before that, Tubo Zanpu Songtsen Gampo sent people to ask the Tang Dynasty for marriage, but it was also successful, and the princess Wencheng who married the Tang Dynasty, with a large number of rich dowries, has already set foot on the land of Tubo.

Therefore, the true pearl Khan Yinan of Xue Yantuo never thought that if he asked Datang to marry a princess so sincerely, he would be rejected by Emperor Li Shimin of the Tang Dynasty, aren't there many princesses in Datang?

The Zhenzhu Khan Yinan of the Xue Yantuo Department, the person sent to the Tang Dynasty to apologize for his sins and ask for marriage, was his uncle.

The so-called heavy gift is 3,000 good horses, and the tribes in Mobei basically have no property such as gold and silver, cattle, sheep and horses are their property, and the trade between the tribes is basically barter.

Li Shimin and the ministers discussed, and the ministers all thought that now that the Tang Dynasty has frequent wars and the national strength has not yet recovered, it is not appropriate to continue to fight with it, and marriage is the best choice.

Li Shimin said: "Yi Nan is the leader of a small tribe, how can he compare with Jieli's strength, it was I who established him as a khan, so he will have today, I hurt him, does he dare to disturb the border?" ”

Zhenzhu Khan Yinan's first marriage proposal ended in failure and was brutally rejected by the Tang Emperor Li Shimin.

However, Zhenzhu Khan Yinan did not give up, and continued to send his henchmen to Datang to ask for marriage.

In fact, the reason why Xue Yantuo's Zhenzhu Khan Yinan had to ask to marry the princess of the Tang Dynasty was that there was no way to do it.

Since the defeat to Datang at the end of last year, Zhenzhu Khan Yinan's situation has been very bad.

Tongluo, servant bones, and other tribes were originally attached to the Xue Yantuo tribe, but at this time, seeing the strength of the Xue Yantuo tribe, their hearts began to be less happy, and they were attached to the Xue Yantuo tribe again, and obeyed the orders of Yi Nan, the true pearl khan.

At this time, the Zhenzhu Khan Yinan, urgently needs the support of the big powers, if he can marry the princess of the Tang Dynasty, then his position will be stable, and the surrounding tribes will be afraid of him, attached to Xue Yantuo, and obey him, the Zhenzhu Khan.

Wasn't it because of the Tang Dynasty that after the Tang Dynasty canonized itself as the True Pearl Khan, the power of the Xue Yantuo Department grew and developed rapidly?

Li Shimin was originally a little hesitant about whether to make peace with Xue Yantuo, but this time, the ministers still insisted, and at this time, making peace with Xue Yantuo was very beneficial to the Tang Dynasty.

At the court meeting, Li Shimin said his two ways to deal with Xue Yantuo, the first is to send 100,000 male soldiers to directly destroy Xue Yantuo, and the second is to agree to Xue Yantuo's marriage proposal, and a princess in the next family will be able to keep peace for 30 years.

Sikong, Shangshu's left servant shot Fang Xuanling stood up and said: "After the chaos at the end of the Sui Dynasty, the national strength has not yet recovered, full of devastation, since Your Majesty ascended the throne, there have been many wars, if you send another 100,000 troops, go to Mobei to attack and destroy Xue Yantuo, it is really not very rational, I hope Your Majesty is cautious, for the livelihood of the world, and kissing is the best way." ”

Chu Suiliang also stood up and opposed the use of troops against Xue Yantuo's troops, and harmony was the best choice.

Li Shimin saw that the ministers were all inclined to make peace with Xue Yantuo, so he said: "I am the parent of the people, Gou Ke is profitable, how can I love a daughter." ”

Anyway, there are a lot of clan girls, just find a clan girl and marry her as a princess, but you can be a 100,000 male soldier, as if you can't.

So he decreed that a woman was selected from among the daughters to be married in the clan and named her a new princess.

The Tang Emperor gave the Zhenzhu Khan Yinan to marry the Xue Yantuo Department with a new princess, and the news spread to Mobei, and the Zhenzhu Khan Yinan was really happy.

Tongluo, Servant Bone and other tribes, seeing that Zhenzhu Khan Yinan had become the son-in-law of the Tang Dynasty, no longer dared to give birth to two hearts, and was afraid of Zhenzhu Khan Yinan again as before, even more than before, and had to closely attach himself to Xue Yantuo and obey the orders of Zhenzhu Khan Yinan.

Because the tribes in Mobei are really inexplicably afraid of Datang, they don't dare to provoke Datang.

Li Lizhi, the princess of Changle, was tormented by illness and completed her short life of 21 years.

Li Shimin and Empress Changsun were very sad about the departure of their beloved daughter Princess Changle, and ordered Princess Changle to be buried in Zhaoling, so that they would always be by their parents' side in the future.

Li Lizhen, the princess of Changle in history, would not die of illness until a year later, but now, because of the sudden rebellion of the eldest grandson Wuji, she was hit hard, resulting in an early onset of illness and died a year earlier than in history.

Li Zhonghua's appearance in the sky inadvertently changed the fate of many people, and Li Liqing, the princess of Changle, is just one of them.
