Because of Li Chengqian's own iniquity, in the next nearly a month, he could only take his daughter-in-law to shuttle back and forth in the major halls of the East Palace, and even during the Shangyuan Lantern Festival, he did not dare to show up, but spent it with his daughter-in-law in the Lihua Palace.

Although Li Chengqian was hiding in Tibet, he knew everything that was happening in the outside world through Ming Wei.

I also know that with Li Wei's efforts in business and the introduction of Li Shimin's policies, the entire Datang is like a huge machine, running at full strength, so that Datang is quietly changing every day.

In particular, some things that have been circulated from the East Palace have been favored by countless princes and nobles and wealthy gentry, and of course, the most obsessive thing is the novel clothes.

Now in Chang'an City, especially those noblewomen, the favorite thing is nothing more than three, holding the mirror produced by the royal workshop, wearing the clothes of the royal clothing workshop, sitting in the royal pastry shop, ordering a favorite pastry, and chatting with their girlfriends, which has become a fashion.

The men, on the other hand, are more likely to eat all kinds of food and drink mellow wine in the royal restaurant.

This kind of life has been staged in Chang'an City, so with the increase in demand, the income of countless people with low-level raw materials has slowly increased.

However, compared to the changes and beauty in the city of Chang'an, the life of Jieli Khan in the northern grassland was not so good, a few days ago, his Turkic army and the army led by Li Jing in the battle of Tietun Mountain, was defeated by Li Jing head-on, so that Jieli Khan directly lost nearly 100,000 armored soldiers.

Jieli Khan, who thought that he had received the support of the Tang family, had to retreat to the grasslands further north, and also made Jieli Khan give up his ambition to continue to go south, but wanted to retreat to the depths of the grassland and recuperate in preparation for another battle in the coming year.

But the army of the Tang Dynasty didn't want to let him go like this, as well as the nearly 200,000 Turkic iron cavalry under his command.

After Li Jing found out that Jieli had run away, he asked his lieutenant Su Dingfang to lead 2,000 men and horses to bite Jieli's army.

At the same time, Xue Rengui, who had already attacked the grassland tribes in the eastern grasslands, also received Li Jing's order to ambush Jieli on the road to the north, waiting for Jieli's arrival.

"No. 1, do you think the marshal's judgment will be wrong, we have been waiting for three days in this place where birds don't, and we haven't seen anyone coming, will they go any other way" No. 4, who was already waiting impatiently, stood behind Xue Rengui and complained loudly.

"Take other roads, it's impossible, you don't know the terrain here, except for this road under our mountain, the rest is no man's land, and there is no big water source, Jieli go there to find death, so we just have to wait here, by the way, I asked you to prepare the things are ready" Xue Rengui looked at the small river in the distance and said to No. 4.

"There are already brothers who have gone to the upstream position with laxatives, but this can really work, it is living water, just our little laxative, how much effect can it have" No. 4 asked Xue Rengui very puzzled.

"As long as the timing is right, it will be more or less effective to launch them at one time when they are stationed, and we don't want to use this way to make them all lose their combat effectiveness, after all, they have nearly 200,000 horses, okay, you go to rest first, I'll stay here for a while" After speaking, Xue Rengui let No. 4 go back first.

Waiting for the 4th to leave, Xue Rengui stood on this unknown hill, looking at the grassland that had gradually become green, and his mood was very complicated.

After receiving the order of Li Jing, the marshal, he took people to investigate the surrounding area, and finally chose this place as the place for this battle, he could think that maybe in a few days, this bleak but vibrant place will be covered by a mountain of corpses and a sea of blood, although he can't bear it, but he also knows that this is their mission as soldiers, and if it goes well, after this war, there will be no more forces in the northern grassland that can threaten the Tang Dynasty, and this huge grassland will also be included in the territory of the Tang Dynasty.

In this way, time passed quietly in a long wait, and several days still did not wait for the arrival of the army of Jieli Khan.

On this day, Xue Rengui went to the front to check as usual, and suddenly there was a huge sound of horses' hooves in the distance, and he knew that it was coming.

He hastened to be informed, and everything went according to plan, while he continued to hide on the hill and observe.

Sure enough, an hour later, a continuous army arrived, stopping a few dozen miles away from them to set up camp, while several pairs of cavalry scattered in all directions to reconnoiter in the distance.

"King, let's rest here today, and when we go on our way tomorrow, when we cross here, we can turn around and head towards Yin Mountain, gathering other scattered tribes along the way, and when we develop again, we must let the Tang people know how powerful we are" In a yurt that had just been built, one of Jieli Khan's staff members was facing Jieli Khan, who was sitting on it.

"Alas, how many more people can there be, those fleeing clansmen also said that there is a demonic army in the grassland, attacking those tribes everywhere, many tribes that were unwilling to submit before have been swept away by that army, in this grassland, can still be gathered, except for us, just like the clansmen further north, so I decided not to go to Yinshan, continue to go north, I want to subdue those people and horses, and in order to avoid those Tang troops, by the way, the pair of Tang troops who have been biting us have been solved" Jieli Khan sighed, Said to the staff member under him.

"The Tang army is still following us, the king wants me to say, it's better to send a large army to destroy them, where they continue to attack like this, the men and horses behind will not be able to stand it, this Tang army, every day does not attack, even a sudden attack, regardless of whether there is a result of the battle and retreat immediately, so that our warriors can not rest well" The staff member looked at Jieli and reported to him.

"If you say that, it's really a trouble, we have to solve them, otherwise it's not good to let them follow all the time, if they still attack the camp in the next few days, let Porto lead an army of 20,000 to destroy them, and the people sent to Chang'an to ask for surrender, have you set off?" said Jieli now with some exhaustion.

"People have already set off, I just don't know if the Tang Emperor will agree, king, you still don't think so much, you haven't had a good rest for a few days, just rest early today and think about the next plan tomorrow" Jieli's staff looked at the tired Jieli and persuaded him.

"Okay, this king will rest first, this matter of camping, you can have more snacks, you can't make any mistakes" After speaking, Jieli waved his hand and let them go down.
