At this time, Yuan Xi, Xin Ping and Wang Kuang were stationed in Chen County, with 5,000 cavalry and 20,000 infantry.

Yin Li could not encircle Chen County, but was only responsible for supervising Chen County, and the contact between inside and outside Chen County was not completely blocked.

The news that the high-level cadres were completely annihilated soon spread to Chen County, Xin Ping, Wang Kuang and others were in a hurry, reinforcements could not come, they could die in battle, but Yuan Xi could not be killed or captured.

Now Huang Zhong's army has arrived in Xiyang City, the distance is far away, there are not many Yanzhou soldiers outside Chen County, if they wait for Huang Zhong to return, they will have no chance to retreat, now is the best time to retreat; Moreover, Chen County is only a few dozen miles away from Ruyang County, and it can be withdrawn on the same day, which is much simpler than the retreat of Gao Gan.

As a result, Xin Ping, Wang Kuang and others quickly reached an agreement and decided to take the risk of retreating.

Before the breakthrough, Xin Ping made a full mobilization, Yanzhou soldiers are few, as long as the infantry maintains the formation of retreat, the Yanzhou cavalry will have nothing to do, they can withdraw to Ruyang County on the same day, they will be safe, and they do not have to carry a large amount of baggage, the speed of retreat is relatively fast, therefore, the morale of the officers and soldiers is still very high, and they are not affected by the high cadres to be completely annihilated.

In order to ensure the safety of the road, Xin Ping made comprehensive preparations, cut down trees and made a large number of antlers, and each chief and commander had to carry one, in case of a situation where they had to set up camp, they could be lined up on the periphery to block the cavalry.

According to Xin Ping's arrangement, 10,000 infantry went out of the city first, and it was led by Wang Kuang's Taishan soldiers, followed by pikemen and sword and shield soldiers, followed by 5,000 cavalry, and finally 10,000 infantry and more than 600 Taishan soldiers.

There are only more than 1,200 Taishan soldiers, all of whom are very strong, equipped with weapons such as hard bows and ring hand knives, complete armor, very strong combat effectiveness, and loyal to Wang Kuang, which is the capital on which Wang Kuang relied on to gain a foothold in Yuan Shao's forces; Yuan Shaojun's archers were relatively few, and the more than 1,000 Taishan soldiers were also the confidence for Xin Ping to dare to retreat in the plains.

The range and power of the infantry bow far exceeded that of the cavalry, and after Yin Li tried it, he dared to fight hard, so he had to let them out of the city.

The reason why Xin Ping arranged 5,000 cavalry in the team and was protected by the infantry was because he felt that these cavalry were by no means the opponents of the Yanzhou cavalry, not to mention the level of training, the quality of the war horses alone was too far behind the Yanzhou war horses, so when facing the Yanzhou cavalry, his cavalry not only had no advantage, but became the object of protection, and he did not dare to let the cavalry break through alone.

Yin Li only has 7,000 infantry, and his combat effectiveness far exceeds that of the enemy, but he does not have an advantage in numbers, and if he fights hard, he will also suffer heavy casualties, which is the result he does not want to see, so he can only outwit; This is the experience he learned in the Qingzhou army.

His strength is cavalry, and the combat effectiveness of 5,000 cavalry far exceeds that of the enemy, whether it is the quality of knights or the quality of war horses.

Therefore, Yin Li let the enemy army out of the city, and then sent 7,000 infantry to take over Chen County, and he personally led 5,000 cavalry to deal with Yuan Shao's army, preparing to use the mobility advantage of cavalry to annihilate the enemy in the movement.

Yuan Shao's army kept the formation out of the city, the team was very spectacular, but the marching speed was very slow, and the team was wide, fifty people side by side, including the cavalry, more than three miles long, which made Yin Li find an opportunity, just create chaos and disrupt Yuan Shao's formation, and these people would become his delicious prey.

Most of the horses of Yuan Shao's cavalry were bought from Gao Shun, and they were all inferior or inferior horses; The worst horses of the Yanzhou cavalry were medium horses, and the officers were equipped with superior or better horses; Wu Chang, Shi Chang, Du Bo and Tun Chang are matched with first-class horses, Junhou is matched with excellent horses, and Yin Li is a Zhonglang general, with special horses.

Yin Li led the cavalry to follow the rear to press the formation, and could attack at any time, sending two divisions of cavalry to constantly shoot arrows and harass Yuan Shaojun's left and right flanks.

At the same time, let the soldiers shout the slogan "surrender or kill" to break Yuan Shaojun's will.

There are a large number of Yuan Shao's officers and soldiers who have been hit by arrows, and as long as they can still move, they must keep up with the pace of the troops; Even if someone was shot, Yuan Shaojun remained unmoved and continued to move forward in formation, thanks to Xin Ping's pre-war mobilization and morale boost.

Yin Li did not believe that the officers and soldiers of Yuan Shaojun were not afraid of death, every time a thousand cavalry were dispatched, even if each person shot three arrows, it was three thousand, even if one tenth hit, it would be a few hundred, and it might not be much at the beginning, and when the number of casualties gradually increased, their psychology would definitely collapse, and the formation would definitely be disrupted.

In the plains, the infantry formation is disrupted, and in the face of the cavalry, it is the lamb to the slaughter.

Therefore, Yin Li ordered the implementation of the wheel tactic, each time a thousand cavalry were dispatched, and after one round of attack, they returned to rest in the team, so that all the cavalry could maintain sufficient physical strength and be ready to cover the kill.

At this pace, Yin Li estimated that it would be difficult for the enemy to reach the banks of the Rushui River before dark, but the conditions at night were changeable, and the cavalry was not suitable for combat, so the battle had to be ended during the day, or the enemy army could be held back, so he sent people back to Chen County and ordered the infantry to prepare food, horse food, and transport a large number of arrows.

Constant harassment, the most reaped of the results are the tun chief, the military marquis, and even the two military horses took turns to fight twice, calling it "enjoyable".

Yin Li knew that his position as a lieutenant general was a bit empty, it was Gao Shun who took care of him and Wu Dun, and his martial arts and strategies were not even as good as these military horses, so he had great respect for several military horses, and the relationship between them was relatively harmonious, which also led to a very good relationship between the officers and soldiers in the army under his jurisdiction, and his combat effectiveness improved a lot.

Even if he was harassed like this, Xin Ping did not dare to send cavalry to fight back, otherwise not only would he not be able to catch up with the Yanzhou cavalry, but he would also be easily eaten; The spear array he prepared was to prevent the cavalry from charging into the formation, but the Yanzhou army only harassed, and left at the first touch, and did not take the bait at all, and Xin Ping was helpless, so he could only be beaten passively but could not fight back.

The Yanzhou cavalry was sparsely formed and fast, and even if they fought back, the hit rate was very low; Their infantry is dense and slow, and has a high chance of being hit.

In a single cycle, nearly 2,000 Yuan Shao officers and soldiers were killed and wounded, and those who were shot and killed had been trampled into flesh by the officers and soldiers and war horses behind them, and the speed of the troops' march was slowed down.

Xin Ping felt that if this continued, before they reached the banks of the Rushui River, the officers and soldiers would either be killed or collapsed; He thought quickly, suddenly, he thought of the circular formation, so he immediately adjusted, the cavalry was in the center, the pikemen and sword and shield soldiers were outside, and the periphery was a circle of antlers, more than a thousand Taishan soldiers were scattered, if the Yanzhou cavalry came to harass, the hard bows of the Taishan soldiers would counterattack.

Taking advantage of Xin Ping's change of formation, he reaped a lot of results, and when the formation was changed, Yin Li injured dozens of cavalrymen, so he immediately ordered to stop harassing, because under this formation, Yuan Shaojun could only be fixed in one place and could not move.

The shields of Yuan Shao's saber and shield soldiers were small and had little defensive effect, and Yin Li was mainly afraid of those infantry archers.

Yin Li thought to himself, if the enemy does not move, he will not move, his cavalry can take turns to rest and eat, and Yuan Shaojun did not carry a lot of baggage, so he would definitely not be able to hold out for a few days to see who could survive whom.

Xin Ping was very anxious in his heart, such a formation, although the Yanzhou cavalry did not dare to fight forward, they could only watch from a distance, but they were also very uncomfortable, this formation is not good for marching and rushing, the longer the time drags on, the more unfavorable it will be for him.
