Ashina Helu was a Turkic nobleman of the Western Turks, and the hereditary protector of the Western Turks.

Since the Eastern Turks were destroyed by the Tang Dynasty, Ashina Helu led his troops to nomadic herding in the north of Yinshan, spying on the various tribes of Xue Yantuo east of Yinshan.

Last year, Ashina Duxun fled to the Ashina Helu Department because of a falling out with Lu Zhi, and informed Ashina Helu of the news that the Tang Dynasty would have a big battle with Xue Yantuo.

Ashina Helu led 50,000 cavalry to the west of Yudu Junshan (now Hangai Mountain) and waited for the outcome of this battle.

At the end of the fourth lunar month, the news of Xue Yantuo's defeat spread to Ashina Helu's tent.

Ashina Helu didn't know that Li Chengqian had either killed or sent all the captured Mobei soldiers to the mine, and thought that the defeated tribal soldiers would flee back to the tribes in a few days.

Therefore, Ashina Helu took advantage of the emptiness in the north of the desert to occupy Xue Yantuo's lair first, and the others had to decide how to deal with it according to the number of young and strong people who had returned from defeat.

After Ashina Helu occupied Xue Yantuo's lair, he calculated every day that he would wait for him to defeat the defeated army that Xue Yantuo had fled back from, and reduce them all to slaves, and the entire Mobei would be his.

-----------------

At the beginning of the fifth lunar month, the thatch under Yudujun Mountain has grown to three feet high.

Under the clear blue sky, the endless grassland, the deep and light colors form a variety of patterns.

In the distance, a bright river meanders like a silver ribbon on the green grassland, and the gurgling water moistens this lush grassland.

On both sides of the river, groups of yellow wild asses, majestic wild horses, horned deer with branches on their heads, Bactrian camels, elf-like antelopes, wild goats, yellow sheep and other wild animals are either running happily, or leisurely gnawing on the grass, or drinking water by the river.

Since Yi Nan led the young men of the Mobei tribes to the south last year, there has not been a large-scale hunt on this grassland, and the beasts here have lived very leisurely at the turn of spring and summer.

Xue Rengui rode on his war horse and raised his eyes to look at the vibrant grassland in front of him, and said with a sigh of relief: "This place is so rich, no wonder His Royal Highness the Crown Prince must send a scribe to record the terrain of the mountains and rivers when he comes, so as to prepare for the future operation of the Tang Dynasty." ”

Xi Junmai, who was next to him, didn't hear Xue Rengui say anything, just stared at the towering Yudu Army Mountain dozens of miles away.

After a while, Xi Junmai's eyes lit up and said, "Brother Xue, do you know the mountain in front of you?"

Hearing this, Xue Rengui also looked up at the mountain in front of him and smiled modestly: "Before coming, Xue really didn't know that this mountain was Yanran Mountain in the Han Dynasty, but His Royal Highness the Crown Prince was a pedantic celestial, and when Xue came, he told Xue that this mountain was the place where the Eastern Han Dynasty Dou rode Shi Yanran. His Royal Highness the Crown Prince also specially instructed Xue to sacrifice a sacrifice at the foot of this mountain in Shaojiao, and died in the Han family during the Eastern Han Dynasty. ”

Xi Junmai sighed after hearing this: "His Royal Highness the Crown Prince is really benevolent and benevolent, and even the heroic spirit of the Eastern Han Dynasty has not forgotten. ”

Xue Rengui smiled when he heard this: "His Royal Highness the Crown Prince has the world in mind, and often says that all my Chinese heroes must be respected, both ancient and modern. ”

Xi Junmai's eyes lit up when he heard this, and he laughed: "Brother Xue and I should be considered heroes here today, right?"

After that, he jerked the war horse, and the war horse galloped forward, and Xi Junmai laughed on the horse and looked very happy.

Xue Rengui also hit his horse to follow, his face was calm, but he thought in his heart, this time he led the army to come, but His Royal Highness the Crown Prince first destroyed Xue Yantuo's army to receive women and children, and it was still far from the Eastern Han Dynasty chariot general Dou Xianle Shi Yanran!

Because Li Chengqian gave them a relatively tight time, and the scope of the Mobei parts was very large, so as soon as the desert was over, they divided their troops into two routes, Xue Rengui and Xi Junmai led 10,000 Tang troops to go straight to the lair of the Xue Yantuo department, and then gathered the small tribes around the Xue Yantuo department after the old nest of the Xue Yantuo department was laid.

He Li was more familiar with Mobei, so he was responsible for collecting the women and children in the outer tribes.

At that time, Yi Nan did not recruit from the Chebi Department when he sent out the army, and the Chebi tribe was still in the hands of Chebi He Li's younger brother Chebi Shamen, and Chebi He Li could use the strength of the Chebi Department to do things, so he didn't bring many soldiers and horses.

As soon as Xue Rengui and his party arrived at the foot of Yudujun Mountain, they were discovered by Ashina Helu's spies.

At this time, Ashina Helu had already rewarded Xue Yantuo's women and children to his generals as slaves, and he himself took his guards to hunt around every day.

As soon as he heard that there were 10,000 Tang troops, he was stunned for a moment, and secretly thought: Even if Xue Yantuo's entire army is wiped out, the Tang army will not be able to come here if none of them come back!

The so-called wounded enemy is 1,000 and self-inflicted 800, the Tang army destroyed Xue Yantuo, shouldn't he lick his wounds in the sound of celebration at this time?

He didn't know that this time, because the Tang army used gunpowder, the casualty rate of the Tang army was greatly reduced.

Ashina Helu still doesn't want to understand what the Tang army is doing in Mobei, and now there are old and weak women and children left in the Mobei departments, which is meaningless to the Tang army.

The grassland tribes must rob each other's people to be slaves after the war, but this is meaningless to China, the men are stupid, the women are ugly, and it is too rude to keep them as slaves, and the family has to sit in a living Hades all year round to deter them.

Of course, if the steppe people surrender on the battlefield, they will also be captured, and the use is generally to sacrifice prisoners when the division is returned to the court.

"Lord Ye Hu, Datang only has 10,000 soldiers and horses at this time, if we win the battle, we will definitely be able to get a lot of good armor." Ashina Helu was thinking about Ashina Duxun next to him, but he smiled and offered him advice.

Hearing this, Ashina Helu turned his head to look at Ashina Duxun, and said with a grim expression: "What do you know?" Since the Tang Dynasty has sent troops, I am afraid that there are more than 10,000 cavalry. ”

Ashina Duxun's face was ugly when he heard this, but he was still unconvinced: "The soldiers and horses of the Tang Dynasty will not come here to hunt, and now that we occupy Xue Yantuo's lair and divide Xue Yantuo's women and children, can we still let them out?"

Ashina Helu knows that Li Shimin is powerful, so he is unwilling to clash head-on with Datang, but as Ashina Duxun said, it is impossible for him to spit out the meat in his mouth now.

"It is rumored that I will order the gathering of a large army to meet the Tang army." Ashina Helu is also a sitting, standing up, and ruthless stubble.

In history, he fell out with the Western Turkic Khan and surrendered to the Tang Dynasty in the 20th year of Zhenguan, and rebelled immediately after Li Shimin's death, which shows that he was never willing to be subordinate.

At this time, he made up his mind and immediately led troops to meet Xue Rengui, in order to destroy this 10,000 Tang army first, even if there were people behind, they could escape with the spoils.

Xue Rengui and Xi Junmai led the army to the foot of the Yudu Army Mountain and followed the guide's guidance, passing through the pine forest one mile in front of them, which was the valley where the Xue Yantuo tribe was located.

Seeing that it was getting dark, Xue Rengui was hesitating to enter the pine forest, but suddenly heard a rumbling sound of horses' hooves faintly from the pine forest.

Xue Rengui and Xi Junmai were also veterans in the army, and when they heard the sound, they immediately knew that there was an army coming from the opposite side.

Xi Junmai frowned and said, "Where did this army come from?"

Xue Rengui stared at the pine forest in front of him with his eyes and said with a solemn face: "It should be the Western Turk Yehu Ashina Helu who dares to compete with the Tang Dynasty here." ”

As the horse's hooves grew louder and louder, they rumbled like war drums.

Xue Rengui guessed that the other party had at least more than 30,000 cavalry, looked up at the majestic Yanran Mountain, shook the reins and carried a spear and rushed towards the pine forest opposite.

Xi Junmai understood as soon as he saw that Xue Rengui was going to the edge of the pine forest and waiting for the other party to come out outside the range of the opponent's bow and arrows, and as soon as the opponent's cavalry walked out of the pine forest, he would meet the Tang army's arrow rain.
