Cao Cao decided to withdraw his troops, but it was not so easy. As soon as Cao Cao's side moved, Li Jing's side found out.

Li Jing had just received reinforcements from Gao Changgong and Wang Yanzhang, and was talking to them. The bravery of the two is also spread among the soldiers, and Li Jing is glad that with the two fierce generals in his hands, he can use even more.

Li Jing just wanted to see how to use these two fierce generals, when he heard a report from the soldiers that there was a building in Cao Cao's camp.

"Let's go up to town and have a look!" Li Jing invited.

Qin Qiong, Gao Changgong, and Wang Yanzhang of course agreed, and among Zhang Yi's troops, Li Jing was the most valued by Zhang Yi, and was more valued than the patriarch Di Qing. If he receives Li Jing's attention, it may be much easier to be promoted in the future. When you are a soldier and fight, it is more about getting promoted and making a fortune and leaving a name in history!

On the top of the city, the four looked at the camp outside the city, and saw that Cao Cao's army was constantly retreating outward.

Li Jing pointed at Cao Ying and said, "It seems that Cao Cao knows that he can't capture Cai Yang, and plans to retreat." ”

Qin Qiong and Li Jing are familiar, "Envoy? Aren't we chasing? ”

Li Jing said with a smile: "Don't worry, you go to the army first and wait for my order!" ”

"Good!" Qin Qiong immediately took Gao Changgong and Wang Yanzhang down to the city to prepare the army.

"You just arrived in Caiyang, do you need to rest first?" Qin Qiong asked.

"No need, I've fought with Cao Jun along the way, and I'm not tired at all!" Wang Yanzhang said indifferently.

It can be seen from this sentence that there is indeed arrogance on Zhang Yi's side, and the battle that has been fought for more than half an hour is just a fight in Wang Yanzhang's eyes, and the tone is too relaxed.

Li Jing waited for Cao Cao to retreat, and then he gave an order: "Let Qin Qiong lead 3,000 people to follow Cao Cao, and if Cao Cao enters Xinye, he will cruise nearby." If Cao Cao continued north, he was harassed. Ordered Gao Changgong to take 3,000 people as Qin Qiong's rear to answer Qin Qiong at any time, in case Cao Cao designed Qin Qiong. Ordered Wang Yanzhang to take 3,000 soldiers and horses to Liu Yuanjing's camp, if the Cao army there withdrew, Wang Yanzhang went north to support Qin Qiong and Gao Changgong, if the Cao soldiers there did not withdraw, then drag them down, and Liu Yuanjing should join forces outside the country to defeat the enemy. ”

The three of them received the order and quickly left the city, but when they reached the outside of the city, Cao Cao and Yu Ban's two armies all retreated, and stayed there after retreating to Xinye. Qin Qiong, Gao Changgong, and Wang Yanzhang also camped outside Xinye City, keeping an eye on the movements of Cao's army at any time.

After Li Jing confirmed that Cao's army had retreated, he immediately met with Liu Yuanjing, went north to Xinye, and continued to confront Cao's army.

The attack and defense of the two sides switched, Cao Cao, who was besieging the city, became the defender, and Li Jing, who was defending, became the besieging party. However, Li Jing had no intention of attacking the city, even if he dragged it like this, he would take advantage. Why? It's because of the supply line problem!

Although Cao Cao has been in Nanyang for several years, there is a lot of grain and grass used in Nanyang, and there is not much leftover, so Cao Cao's supply of grain and grass comes more from Yingchuan County, that is, from Xuchang. Although Zhang Yi's grain and grass come from Chaisang, the distance is very long, but the efficiency of water transportation is very high! As long as the ship is not sunk, a grain ship about the size of a ship can transport the grain used by a thousand soldiers for ten days, and the consumption is only ten days of food for fifty people, and one-twentieth of the road consumption is much stronger than Cao Cao's road consumption of one or even two times, and Li Jing can consume Cao Cao to death just by consuming grain and grass!

And Li Jing has another backhand, that is, Master Shang.

Fuyang, where Master Shang and apprentice are located, is not very far from Cai Yang, and he has already sent someone to contact Li Jing. When Li Jing was besieging the city of Cao Cao, he gave orders to Shang's master and apprentice.

It's just that the speed of news transmission is a bit slow, and there are two ways for the messenger to go from Caiyang to Fuyang. If you go to Huyang and Ping, it is easy to be caught by Cao Jun, so you go to Xiangxiang, enter Tongbai Mountain, and walk to Fuyang on the road. After the envoy arrived in Fuyang, Master Shang and his apprentice had already gone to the ravine to ambush, and the envoy went to the ravine again.

When Master Shang got Li Jing's order, Zhang Yizheng had already broken through Xiangyang. After receiving the order, Master Shang and his apprentices immediately marched west and attacked the Ping clan.

The city of Ping was small, and the master and apprentice broke it in less than a day. Then he left 500 people to defend the city, and continued to the west without stopping, heading straight to Yuyang.

Cao Cao left less than a thousand people in Yuyang, while Shang Shi's apprentices were as many as five or six thousand. Master Shang and apprentice came from afar, and did not bring siege equipment, but they were not helpless. Zhang Yi is an expert in raiding, and the master and apprentice were not allowed to do anything, so he took people to rest first, and after nightfall, he selected two hundred skilled people to steal the city.

The two hundred men reached the bottom of the city and climbed to the top of the city by scratching. This city is only three or four zhang high, and it can be thrown with your hands, not to mention that Zhang Yi's army is also equipped with a strong crossbow. The crossbow fires and scratches, fixes the ropes, and after climbing to the top of the city, it follows the head of the city and kills the city gate.

At night, Cao Jun's defense was lax, and the city gate was easily opened, and the master and apprentice were allowed to enter the city.

After Master Shang and his apprentices entered the city, they immediately rewarded the whole city to prevent leakage of news.

Master Shang took Yuyang, which was the day before Cao Cao entered Xinye. It is said that no book is written without coincidence, and there are many coincidences in reality, and these coincidences often determine many major things, such as the story of a nail destroying a country, which is the case.

Cao Cao retreated to Xinye, but he didn't want to stay in Xinye for a long time. Xinye is too far away from Xuchang, and the supply line is too long, and the gains outweigh the losses. During the Battle of Guandu, he knew the importance of short supply lines, otherwise he would not have retreated to the Guandu area by himself. He occupied Wancheng before, and he didn't continue to attack Nanyang because of this road, the supply line could only give him a strategic space to Wancheng, and he couldn't stand it any longer.

So Cao Cao took Cheng Yu and Zhang Xiu to continue to retreat, and after retreating to Yuyang, he planned to go into the city to rest.

As a result, at this time, Master Shang and his apprentice came out of Yuyang City, and Li Jing led his troops to attack later.

Cao Jun was caught between the two sides, and he was in chaos all of a sudden. The four fierce generals flanked back and forth, and in the case of a surprise attack, no matter how elite the troops were, they couldn't stand it, and Cao's army collapsed all at once. Zhang Xiu and Li Tong protected Cao Cao and Guo Jia to retreat safely, and Cheng Yu and Li Dian also organized some soldiers to retreat from the battle.

Only at the end, Yu Ban once again showed his ability, quickly organized a thousand people, and then kept gathering soldiers to stop the four, so that the Cao army was not wiped out.

After chasing Cao Cao outside the city of Jianyang, and seeing Cao Cao enter the city, Li Jing ordered the army to be stopped and returned to Yuyang.
