In the shouts of Jieli Khan and the calm of Princess Yicheng, Li Yan slowly stepped into this place.

"Tie them up, and when General Cheng and them arrive, escort them back to the court."

Li Yan glanced at Jieli Khan indifferently, not caring about his incompetent rage at all, the current Jieli Khan no longer had any resistance, Li Yan naturally did not need to continue to expend energy on him.

"Tang Jun? No way! How could the Tang army enter my Turkic royal city! No way! ”

Jieli Khan couldn't believe what was happening in front of him, how could the Tang army come here quietly? Jieli Khan simply could not understand.

"When there is a snow storm in winter, you should be on guard, but unfortunately you don't."

"Okay, shut his mouth, press him down and guard it well, don't let him die."

Li Yan was a little annoyed by the voice of Jieli Khan, so he sent someone to take him away from here.

While Jieli Khan was escorted away, Princess Yicheng just watched all this silently.

She is just a princess of the previous dynasty, and now that the Tang Dynasty has broken through the Turkic royal city, presumably she will not have any good results.

Princess Yicheng sighed in despair.

"You should be the former Princess Sui Yicheng."

Li Yan naturally saw this middle-aged woman, and he didn't need to think much about Li Yan to judge her identity.

The face of the Han people, at the age of thirty or forty, also appeared in the palace of Jieli Khan, and all kinds of clues clearly pointed out the identity of this woman.

"You stay by yourself for the time being, I will send someone to bring you food in the next few days, and when the army arrives, I will send someone to Chang'an to meet my Majesty the Emperor of the Tang Dynasty."

Li Yan is very aware of Princess Yicheng's life, she is a woman with an extremely patriotic heart for the Sui Dynasty, even after the fall of the Sui Dynasty, she is actively seeking to restore the country.

Now located in Dingxiang City, which is located between the Tang Dynasty and the Turks, there is a puppet Sui regime, during which there is the handwriting of Princess Yicheng.

Li Yan also knows very well that this Princess Yicheng is even more pitiful, after she married the Turks, she married four khans successively, and was inherited by the Turkic khans from generation to generation, and her fate can be described as extremely miserable.

Because of this extreme ideology, Li Yan knew that Li Shimin would not tolerate her.

Even if Li Yan brought her back to Chang'an, I was afraid that in less than a year, she would still lose her life.

"Thank you, general."

Princess Yoshinari is still wrapped in a futon.

To be honest, she felt more hopeless than ever before.

Perhaps before the Tang army broke through the Turkic royal city, she was still thinking about using the power of Jieli Khan to let the Sui Dynasty continue to exist, but now that Jieli Khan has fallen, she knows that the Sui Dynasty regime in Dingxiangcheng will not last long.

At this moment, her heart was like ashes.

Li Yan walked out of the door slowly, he didn't have time to think about the idea of Princess Yicheng or Jieli Khan, and a trace of emotion appeared in his heart for a long time.

"In the second year of Zhenguan, I, Li Yan, led the army to destroy the Eastern Turks, which can always leave a name in history."

Li Yan sighed in his heart.

I think he was just a time-traveling otaku at the beginning, and after a long struggle, he actually achieved such a grand goal......

Just when Li Yan became more and more emotional, Ge Dahai came to Li Yan's side.

"Boss, the internal cleanup of the royal city has been completed."

Ge Dahai's report on the military situation interrupted Li Yan's train of thought.

"Send someone to arm, do you still need me to teach you?"

Li Yan responded angrily.

It was rare for him to sigh in his heart, and the pride was interrupted just after a sign was brewed, so that Li Yan's mood was a little uncomfortable.

"Wait a minute! I'll write a letter, and when the deployment is completed, you will immediately lead people to the edge of the desert, and wait for the army to arrive in Mobei, and after the army arrives, you must hand it over to General Cheng as soon as possible. ”

Li Yan's expression became serious.

Now when he discussed tactics with Cheng Yanjin, he didn't mention at all that he would defend the city after capturing the wolf tent, so Li Yan had to reconnect with Cheng Yanjin as soon as possible to reconnect with the battle plan.

After the army arrived in Mobei, it must start a war as soon as possible to force the tribes of Mobei to converge towards the king's tent.

In the process, Li Yan would completely blockade the royal city and never let any Turkic tribe know that Jieli Khan had been captured alive.

In this way, in the absence of a commander, the tribes will definitely think of leading their troops to this place, and then Li Yan will be able to launch a siege and completely clear the Mobei grassland!

"Okay, boss."

Ge Dahai didn't dare to hesitate, and hurriedly ran to run errands.

……

Two hours later, the sky was light, the sun was shining in the royal city, and everything seemed to be going on as usual.

The tribes of the entire Mobei grassland are busy with various matters after the snow disaster, either hunting and collecting food, or gathering to bury their fellow tribesmen.

All in all, no tribe has discovered the destruction of the Ashina tribe and the anomalies in the king's tent.

And so it went on for seven days.

During this period, Turks occasionally went to the king's tent, but after eating the closed door, they all chose to leave on their own.

After all, during the reign of Jieli Khan, he often ignored the ministries and always showed self-respect.

The messengers of the ministries have long been surprised.

It was on the seventh day that a tribe on the grassland finally discovered the anomaly.

They found that the Ashina tribe, a tribe that relied on itself to be a royal family and grabbed prey everywhere every day, mysteriously disappeared.

After the exploration, the Turks were horrified to find that the Ashina tribe had been wiped out silently and tragically!

Just as they were about to tell the king's tent, something really frightened them!

The 30,000 army led by Cheng Yanjin, after a seven-day trek, completely pacified Monan, crossed the Gobi, and successfully advanced into the Mobei grassland!

When Cheng Yanjin led the army to Mobei, he received a letter from Zhang Dazhu as soon as possible.

When Cheng Yanjin saw the letter, the whole person was in a trance.

"The royal city has been breached, Jieli Khan has been captured alive, General Wangcheng divided his troops to attack the various tribes quickly, and tended to make the various departments gather to the royal city......"

Cheng Biting Jin's head was dizzy.

He originally thought that Li Yan would be deflated after entering Mobei, so he hurriedly led people across the Gobi to come here.

Who would have thought that the first news he received after arriving was that Li Yan had solved the main goal of the war, and all that was left was the task objectives that were large in number but extremely simple to complete......

"Generals, marshals have sent letters, Jieli Khan has subdued the law, and now you ......"

Dispatching troops is still quite good at this kind of thing.

What's more, in the past seven days, except for Zhang Dazhu, the other two scouts were not idle, they basically searched for information on the entire Mobei, and even drew a simple map.

In this case, Cheng Yanjin did not encounter any difficulties at all in the process of implementing the strategy.

In just two days, the entire Mobei has become a place of war.

The tribes, already weak, took all the elites to the royal city.

A war of encirclement that annihilated the entire Mobei Turkic tribe slowly kicked off.
