Tuyuhun knew that the Tang Dynasty was going to recruit a large army to attack, and he was not afraid, Tuyuhun had absorbed a large number of miscellaneous beards after many years of recuperation, and now there are hundreds of thousands of people who control the strings.

The strength is stronger than Xue Yantuo, and Murong Fuyun, the Khan of Tuyuhun, is ambitious because of his experience in fighting with the former Sui, and wants to defeat the Tang Dynasty.

In that year, the Sui sent a large army to attack Tuyuhun, and Tuyuhun fled westward, with the help of the plateau climate and familiar with the terrain, the Sui Dynasty army could not catch up at all.

After the Sui Dynasty army came here, there was a lot of altitude sickness in the army, and it was impossible to stay here for a long time, and finally the army could only withdraw after setting up a county here.

It's just that after the Sui Dynasty withdrew, Tuyuhun began to return here again. In the end, the Sui Dynasty spent a lot of money and soldiers, but it still did not completely conquer Tuyuhun.

Now Murong Fuyun has gathered a large number of Zahu, Turkic and other tribes, and his strength has increased greatly, after seeing the response of the Tang Dynasty, he only felt that the Tang Court was weak, so he said loudly: "This is a thousand miles of plateau, it is the territory given by God to Tuyuhun, and the people of the Central Plains will be cursed when they come here like the former Sui more than ten years ago!" ”

"Their so-called Hao Tianwen King can't control this, and the heavens won't bless him Li Shimin!"

"The Tang army will only be cursed when they come here, they will be tortured by the curse and dying, and then they will be easily defeated and killed by the iron cavalry of this king!"

Murong Fuyun and the nobles of Tuyuhun held a banquet, and then issued an order to clear the walls and fields, and all the tribes were evacuated to the western plateau.

Not a single cow or sheep can be left, he wants to let this long supply line drag down the Tang people, and let the Tang people be cursed and die a painful death on the plateau.

Murong Fuyun felt that the current strength of the Tang Dynasty was not as good as that of the former Sui, and how could the Tang Dynasty do what the former Sui had not done back then?

The Sui Dynasty was so powerful that there were millions of armor soldiers, the grain was piled up in the barn, and a single campaign could mobilize millions of people, but even such a powerful Sui Dynasty did not let Tuyuhun surrender, let alone the Tang Dynasty.

Although Murong Fuyun was very arrogant, not everyone among the nobles of Tuyuhun was like him. In the fourth year of Zhenguan, Tuyuhun also sent an envoy to Chang'an.

This group of Tuyuhun nobles came to Chang'an and saw the prosperity of Chang'an City, the prosperity of the Tang Dynasty, the momentum of the Tang Dynasty, and the great military might of the Tang Dynasty.

At the same time, I also met the Heavenly Khan.

They know very well that although the current Tang Dynasty is not as good as the former Sui at its peak, how can Emperor Yang of Sui compare with the Tang Dynasty Holy Son of Heaven and Tian Khan?

Just those families of the former Sui. If you put a pig on the throne, you will not be completely defeated in just ten years of hard work.

Can Emperor Yang of Sui be compared to His Majesty the Emperor, who was revered as the Heavenly Khan by the steppe tribes?

What's more, the current Hexi and Hehuang are not full of nonsense and sparse people. Datang can use the land of Hehuang as a logistics base to supply the military rations of the front-line army.

How powerful the DTZ was at the beginning, there were hundreds of thousands of people who controlled the strings, and hundreds or even tens of millions of tribal people. Coercing the grassland, Xue Yantuo, Hui Hui and their Tuyuhun are all looking up to their noses.

And now?

The DTZ was wiped out, and the grassland became the sphere of influence of the Tang Dynasty.

Those Tang people fought on the steppe, the territory where the Hu people were best at fighting, and the Turks were defeated. Those Dons even dared to attack in the snow.

With such a powerful army, can Tuyuhun really be able to resist?

The Holy Son of Heaven of the Tang Dynasty ordered the army to come to attack Tuyuhun, and these people knew very well that this time it was not only the Tang Dynasty, but also a large number of servant troops from the grassland tribes and the Western Regions tribes.

It's just that they are auxiliary soldiers and servant troops, but their strength is no worse than Tuyuhun. Datang may not need to prepare too much grain and grass.

And it's so easy to evacuate westward to the ice sheets?

The living conditions on the ice sheet are extremely harsh, and hundreds of thousands of Tuyuhun have retreated here, and it is not easy to survive here.

They will also face a lack of food, which is okay for a short time, but once it is a long time, they can't stand it.

These Tuyuhun nobles looked at their ambitious king worriedly, and they were skeptical that they would be able to defeat the wise and wise Tang Dynasty Saint Son.

But these people didn't dare to say it, Murong Fuyun was not a good stubble, otherwise his brother Murong Fushi would not have died back then.

With the issuance of Li Shimin's edict, the imperial court dispatched 20,000 troops, and at the same time, Li Shimin, in the name of Tian Khan, launched a conscription order to recruit troops and horses from various departments of the steppe and the countries of the Western Regions.

The edict of the Holy Son of Heaven and the Heavenly Khan soon spread all over the world, and after receiving the edict, the various departments of the steppe began to gather troops and horses to go to Hexi to enlist in the army.

Soon, the countries of the Western Regions and the various tribes of the steppe gathered an army of 50,000. Coupled with the 20,000 elites of the Tang Dynasty and the 5,000 soldiers and horses stationed in Hehuang, Hexi, a total of 75,000 people, and then claimed to be 200,000 troops, ready to attack Tuyuhun.

Originally, it was best to send Li Jing as the commander in chief in this big war, but Li Shimin considered that the climate on the plateau was harsh, and Li Jing was already over 60 years old.

So he wanted to use Wang Xuanji as the commander, but after Li Jing learned about it, he went to the palace in person and strongly requested that he lead the army to conquer Tuyuhun.

Li Shimin thought about it for a while and finally agreed, but in order to prevent accidents, he ordered Wang Xuanji to be the deputy marshal.

Then send a large army to attack Tuyuhun.

Wang Xuanji has been in the land of Hehuang for several years, and he has been quite effective, and there is no need to mobilize grain and grass from the Central Plains, and the grain and grass in the land of Hehuang are enough for 100,000 troops to use for half a year.

The Tang coalition army came to the land of Hehuang, and the Tang army soon fought Tuyuhun. Tuyuhun's strength is weaker than that of the Turks, how can it be the opponent of the Tang army.

Three encounters, consecutive defeats.

Despite this, Tuyuhun did not suffer much loss, and several defeats were also small-scale operations.

Tuyuhun was also a cavalryman, and he was very familiar with the surrounding environment, and as soon as he saw that the situation was not good, after paying some price, he quickly withdrew.

After Murong Fuyun saw the strength of the Tang army, he immediately decided to lead the army to retreat westward.

Even when retreating to the ice field, Murong Fuyun was worried that the remaining grassland would provide pasture for the Tang army's war horses, so he ordered people to burn all the grasslands.

"Order people to burn the pastures, throw sick and dead cattle and sheep into the water sources, so that those Tang troops can't get a little supply, drag them down, and wait until they are sick, thin, and can't stand it, and at that time, it's time for the Tang people to see the sharpness of our scimitar!"
