On the grassland, the Tang army was moving, and at this time, the cavalry became the main force.

The infantry returned to the east of the Wolf Mountain Range, cooperating with Cheng Biting Jin to attack Liang State, and on the other side, Cheng Biting Jin and Wei Chi Gong had almost taken Liang State and the puppet Sui.

At this time, the grassland is running for thousands of miles, and the infantry can't keep up with the speed of the march, so it's useless at all, so it's better to let them go to Liang Guo to get some military merit, otherwise it's not a matter if they come out without a harvest.

And with heavy grain and grass or something, Li Jing also notified the logistics director, Yang Cixin, who was the assassin of Lingzhou at the time, this is the former Sui royal family, of course, and now Li Tang's courtier.

Born in Hongnong Yang's family, he is still Yang Guang's cousin according to his generation, but this relative is a little far away, so the impact in the process of fighting is relatively small, and now he is also a senior official of the fourth grade.

Most of the grain collected from Lingnan was transported all the way north to Lingzhou, where he and the local Zhichong Prefecture guarded it, and then handed it over to the quartermaster after the army set out for the expedition.

It's just that Yang Cixin got the holy decree and became the general manager of logistics, although he still dealt with the quartermaster, but he also got his name with Li Jing.

Li Jing informed him this time, asking him to send all the heavy grain and grass to Cheng Yanjin's side, and the 40,000 infantry had been transferred to the Liang position, and the cavalry on their side did not want grain and grass, and directly raided the grassland.

This time, the horses Li Jing brought from Datang were specially selected, and most of them were mares, why? Because considering that when entering the grassland to fight, the logistics line is too long, if you can't catch it, you can also use mare's milk as a service.

In order to prepare for the battle this time, Li Er can be said to have been doing it secretly since the Battle of Jingyang, otherwise where would there be so many mares who happened to be still lactating?

I have to say that Li Er is indeed a very vindictive emperor, in the ninth year of Wude, the Turks hit Jingyang City, this time he is actually preparing to retaliate back, even if it goes on according to the original plan, he has a backhand.

Before Hou Junji left Beijing, he gave this loyal horse boy a secret decree, if the things on the grassland were settled, according to the established plan, the three clans reached a balance, and Hou Junji also wanted to go to the king of the three clans of the grassland to show off his might.

But I didn't expect that the three tribes of the grassland actually designed a trap for the Tang Dynasty, this time not only Hou Junji was going, but even Li Ji and Li Jing were ruthless, ready to really teach these three nomadic aliens on the grassland a lesson.

Even through this action, the three tribes of the grassland were directly included in the rule of the Tang Dynasty, and the ruling ability of the Turks, Hui and Xue Yantuo was completely eliminated.

Now is the time when the three tribes of the steppe are the most empty, and the Western Turks in the west may move eastward at any time. Instead of cheapening the Western Turks, it is better for Datang to shoot directly.

The old and weak women and children have never been in the consideration of the generals of the Tang Dynasty, and the fault in the green and strong grassland is a godsend, not a great opportunity created by the Pure Yang Immortal for the Tang Dynasty, and it must not be given up.

Therefore, the 50,000 Tang Iron Cavalry directly waved north, preparing to take over the dominance of the entire grassland, and even divided the troops into three roads and directly began to advance in three directions, each of which would be responsible for the territory of the original tribe.

First of all, Li Jing chose the Turks, because he and the Turks had some old grievances that needed to be settled. And Li Ji was ready to take down Hui after Hou Junji selected Xue Yantuo.

The three cavalry rolled away in three directions, but Lu Hanyang stopped in place, he was not going to go to the north, anyway, there was basically no resistance in the grassland now.

At this time, he was ready to go west, and if the Western Turks waved their troops to the east, he would also teach them a lesson. After all, this northern grassland is already in the bag of the Tang Dynasty, how can you let others pick peaches.

However, Lu Hanyang is not ready to exterminate the Western Turks now, because at this time, the Tang Dynasty is not capable of ruling such a large territory, and the northern grasslands are enough for the Tang Dynasty to digest it well for a long time.

This war, from the division of the grassland prepared at the beginning, and the action of taking the opportunity to seize the Liang State and the puppet Sui, directly turned into a real external expansion that now includes the grassland as a target.

This time, the credit of Li Jing, Li Ji, and Hou Junji is great, and of course, Cheng Yanjin and Wei Chigong are not small.

After all, the merit of expanding the territory and opening up the territory is the greatest, and destroying the enemy country is the supreme glory of the general. Hou Junji and the five of them are all due to such achievements. The Turks have always been a major problem in the northern part of the Tang Dynasty.

Hui Hui, Xue Yantuo is also a large tribe that is no different from the Turks, although the Liang State and the Puppet Sui are smaller, but they are the original land of the Central Plains Dynasty, and the credit of recovering the lost land is enough to make up for the gap in the land area.

Moreover, the grassland is too far away from the Central Plains Dynasty and is also an inconvenient place, the land is vast and human-shaped, and the habit of herdsmen living in pursuit of water and grass is even more incompatible with the farming people.

For the grassland, the Central Plains Dynasty is very greedy, but it is not to say how rich the products are, after all, in this era, the grassland has no other use except to provide meat.

Wool, minerals in the grasslands, and so on are not yet ready for development. Therefore, the Central Plains Dynasty wanted to conquer here, mainly because it wanted to consolidate its own border defense, not that it must turn this place into its own ruling area.

Because of this era of underdeveloped communications, the rule of these places is really very thin, after all, it takes more than a month to go back and forth, what happens, report, and then when the approval is processed, the daylily is cold.

But it is undeniable that this time it is indeed the fact that the Central Plains Dynasty expanded its territory to the north for thousands of miles, and the Tang Dynasty army swept the grassland, and directly exterminated the resisting grassland forces.

In the grassland tribe, they slaughtered cattle and sheep as supplies, and then swept all the way over, completely taking down the last strength of the three grassland tribes.

And Cheng Yanjin has surrounded the national capital of Liang State, and with the cooperation of 50,000 foot soldiers from west to east, he quickly took all the places of Liang State except for the national capital, and this so-called capital was deliberately left by him.

At this time, Wei Chigong captured alive the so-called emperor of the puppet Sui, and with the support of the Turks, Yang Guang's grandson Yang Zhengdao. This is a little radish head in his teens.

With the support of her aunt and grandmother Princess Yicheng and grandmother Empress Xiao, this little radish head became the emperor of the pseudo-Sui, of course, this is the name of the Tang Dynasty, but in the Turks, it is called the King of Sui.

Because of his people, most of his courtiers were the common people and officials of the Central Plains who had escaped from the military disaster or were captured by the Turks. These people were given to Yang Zhengdao by Jieli at the beginning, and his status was lower than Jieli.
