However, when the two armies encountered, Bu Lishe discovered that Xue Yantuo had invented a new tactic of foot combat, with five people as a combat group, four of whom fought on foot in front and one in the rear to take care of the war horses, cooperating with each other, and after victory, the horses were given to the infantry to pursue. Xue Yantuo was shot to death, just like when dealing with the Hexi army, thousands of soldiers died on the hundreds of steps of the charge, the Turkic army was defeated, and the loss of 20,000 elite horsemen in the first battle was captured by Xue Yantuo 4,000 soldiers and 5,000 horses.

When Bu Lishi returned to the Lightning River, he was already emaciated, not to mention the lost army, even the 10,000 people who fled back with Bu Lishi were mostly wounded and had no fighting spirit. As soon as the coalition forces of the Murowei and other tribes heard that their hometown was under attack, they were homesick and did not want to stay in the Lightning River, and found various reasons to leave; Bu Lisheh also asked to retreat to Dali City, but finally met their request and sent the coalition forces back to rescue.

This is also a decision that Zhao Deyan has no choice, there is only attachment on the grassland, there is no loyalty to talk about, leaving these people in the Lightning River, and worrying that someone will see that the Turks are not good at the time, so it is better for everyone to simply do it. In the face of Bu Lishe's retreat with his clansmen, leaving less than 10,000 defenders, Zhao Deyan could only let the Turkic people who could hold weapons, regardless of men, women, and children, be armed, and reserve food, arrows, stones, and wood.

The Lightning River was in chaos, and he couldn't hide the long-awaited Tuli in the city, and Tuli understood that his opportunity had come, and after arranging for the messenger to report to Anzhou and Zhuo County, he immediately sent people to the Lightning River to spread the news, and he was willing to accept the Turks. A large number of Turks fled to the city, but the Sui army came faster than Tuli expected, especially when they saw that the general who led the team turned out to be Xu Shiji.

As a left-behind guard in Zhuo County, Xu Shiji should be in charge of Zhuo County and control Hebei; But according to the speed of the messenger's delivery, I am afraid that Xu Shiji appeared in the city of Pin before even Zhuojun arrived, and the only explanation was that because Yang Chong was in Zhuo County, Xu Shiji could lead the army to the battle, and he had already left the Great Wall and arrived in the Anzhou area.

Tuli guessed correctly, because Yang Chong believed that the Turks would be defeated, Xu Shiji had actually led an army of 30,000 to Anzhou, and immediately led 45,000 people to set off when he heard the news; This was a good opportunity to defeat Xue Yantuo and determine that the Great Sui was the hegemon of the Northeast, and Xu Shiji had been waiting for a long time. Listening to Yang Chong and Tianqi talk about the combat methods of Xue Yantuo's infantry army, Yu Juluo and the others felt that the tactics of the Hexi army were similar, so where did Xue Yantuo's bow and crossbow come from, and it was time to solve the mystery.

After the main force of Commander Xu Shiji joined with Tuli, he marched all the way to the Lightning River, Yi Nan had captured the left city of the Lightning River, and Zhao Deyan led the Turkic army and people to defend the right city and was fighting hard. Xu Shiji sent someone to spread the message to Yi Nan, the Great Sui hoped that Mobei and the Northeast would be peaceful, Xue Yantuo and the Turks should be bounded by the desert, and the Great Sui did not want to see anyone cross the border to invade, and hoped that Xue Yantuo would choose the good and withdraw the army from the Lightning River.

After receiving the letter, Yi Nan led the vanguard of 30,000 to go first, and came to Huluchuan to greet him. Xu Shiji led the troops to see it from afar, and ordered Liu Heimin to lead the army, with Tuli and Zhang Jinshu as the vanguard, and 20,000 cavalry rushed directly to Xue Yantuo's army, and the sound of rolling hooves was like thunder, and the dust on the grassland suddenly rose to the sky. Yi Nan did not dare to flee north, and on the one hand, he sent people to supervise the army behind, and on the other hand, he set up a formation to meet the battle.

In order to facilitate the display of tactics, Xue Yantuo used the trump card of infantry winning tactics and deployed a formation of more than ten miles in Hulu River; Xu Shiji ordered the Turkic cavalry of Tuli to charge into battle, and Yi Nan's tactics were really powerful, and Tuli was defeated with just one charge. Xu Shiji ordered the Sui cavalry to assault, but as a result, Xue Yantuo's people were all shot, and most of the Sui army's war horses were shot to death; Xu Shiji was furious and ordered the Sui army to dismount and fight with foot with spears.

The Sui army studied Xue Yantuo's tactics, and in fact, the cavalry that went ahead included the Wagang battalion established by Xu Shiji himself in imitation of the Hubu battalion, which was also composed of the elite of the selected infantry combat, with a shield in front and a spear behind it; Under the cover of the shield army, the Sui army did not pay many casualties and rushed into Xue Yantuo's position.

As soon as the two sides came into contact with each other, they were superior and inferior, and the spears of the Sui army were long, and unlike the Turkic spears, they were difficult to cut; The machetes of Xue Yantuo's warriors were short, and the Sui army suddenly gained the upper hand in the hand-to-hand encounter, stabbing them one by one, and the enemy army fell like a stake. Seeing that there was a gap, Xu Shiji ordered Zhang Jinshu to lead 5,000 cavalry to attack, specifically kill the warriors who led the horses of Xue Yantuo, and plundered and shot the horses of the Xue Yantuo people to death.

When Yinan discovered the purpose of the Sui army, he had lost a third of his war horses, so he could only order the withdrawal of thirty miles, and was chased and killed by the Sui army all the way, beheading more than 3,000 levels, and capturing 5,000 Xue Yantuo soldiers who had no time to escape. When Xue Yantuo's whole army arrived, Yi Nan reorganized and fought again, and more than ten armies on both sides set up a battlefield in the north of Hulu River; Xu Shiji grabbed the upper hand, ordered the Sui army to release the airship, under the bombardment of the thunder, Xue Yantuo people struggled to support for two hours, and finally couldn't resist, Yi Nan escaped.

Xue Yantuo was defeated in front of the spears and heavenly thunder of the Sui army, including 20,000 soldiers being captured, and losing more than 40,000 troops; Liu Heimin and Zhang Jinshu led 20,000 cavalry to pursue 200 li, captured more than 20,000 Xue Yantuo civilians who were on the way to retreat, and rescued 15,000 captured Turks. However, Tuli and Zhao Deyan were a little dissatisfied, and the Sui army only dispatched an ordinary army and chased hundreds of miles, and if they pursued two hundred miles like the Turks, the effect could be better. Xu Shiji replied coldly to the two: "From the time the Sui army was dispatched, the final decision-making power was in the hands of the Great Sui. ”

This time, the booty of the Great Sui, more than 40,000 Xue Yantuo's captives, 50,000 cattle and sheep, more than 10,000 war horses, and a large amount of grain that Xue Yantuo snatched from the Turks, the effect was much better than that expected by Yang Chong, Xu Shiji and others; Leaving Yi Nan, the Xue Yantuo people had no choice but to fight the Turks to the end when they lost their materials and population. Therefore, when Xue Yantuo's envoy Hun Jin Zhe sent a descending table and three thousand war horses, hoping that the Great Sui would forgive; Xu Shiji agreed that as long as Xue Yantuo did not attack the Lightning River, the war would be over.

Regarding the garrison of the Lightning River, Xu Shiji refused with Yang Chong's order, Zhuojun had made a plan, under the premise that the Turks did not make a clear statement, occupying the Lightning River was only a temporary pleasure, and the current situation of the great enemy could not divert the Turks of the Lightning River, once Xue Yantuo withdrew the army, the Turks turned their faces, and the consequences were unimaginable. And Tuli is actually an unstable factor, in the current state, he has not completely given up on Khan's dream and returned to the Lightning River, which is likely to stimulate the unstable factor in his heart.
