Cheng Yu nodded: "just to ensure 15000 elite combat power, less than 10000 garrison can't stop the attack of Sizhou army." With that, he turned to Weizi and said, "Mr. Wei, you have been in Puyang for such a long time. You should know the situation in the city. How many soldiers can Puyang recruit?"

At this time, he already knew that his family had been killed by Huangfu Chaobo, and the whole population had been assigned to Hedong Salt farm as slaves. Hearing Cheng Yu's question, he immediately gritted his teeth and said, "Huijun division, there are more than 58000 people in Puyang City. If you want to be strong in the city, you can be the Lord There are 12000 recruits. "

At this point, Cao Cao can't understand Cheng Yu's meaning. Since Puyang can't keep it, he can't take advantage of it. Huangfu Chaobo recruited all the elite soldiers in the city to resist the attack of Sizhou army. Who cares about him in the future.

It's Cheng Yu. Even if the Sizhou army controls Puyang, it will be a big burden. The city with tens of thousands of people has been recruited. After a war with Sizhou army, it is estimated that half of them will die on the top of the city. At that time, the people in the city will not blame Cao Cao, because he has already run away, and there will be endless troubles after the State Army becomes the new ruler here.

"Well, Mr. Wei, it's up to you to recruit soldiers in the city. From tomorrow on, the original ten thousand Garrison and the ten thousand newly recruited soldiers will guard the city. Our fifteen thousand elite will be responsible for assisting. When the time is ripe, we will break through and leave..." As soon as Cao Cao made a decision, he ordered;

"how many elite of these 20000 soldiers can be left in the end, we will take them with us at that time. As for the city," Cao Cao sighed, "still don't..."

"The end will take orders!" Xu Rong soon found out that when the Sizhou army attacked the city wall, it would soon be able to attack the city wall, but the soldiers who attacked the city wall would soon be driven down from the city, and so on.

Xu Rong saw all these in his eyes. At a glance, he saw that the main forces guarding the city were some newly recruited soldiers, but behind them there were a large number of elite soldiers waiting for them. Once he found out where the soldiers were not enough, there would be elite soldiers to make up for them. Cao Cao was training.

However, even if Xu Rong knew it, what happened? Cao Cao is training, but Xu Rong is also training. Although these 30000 soldiers are veterans, there is still a big gap from the elite of the barracks. Now that the garrison of Puyang City is far from enough to let himself down, Xu Rongzheng is good at training in rotation.

In the next few days, Xu Rong still arranged the war as before. During this period, he was attacked by elite soldiers and horses from time to time. Although he let Cao Cao Jun guard the city wall every time, Cao Cao Jun also lost a lot of elite soldiers and horses.

Just as Cao's generals were secretly proud of their success, in the early morning of October 20, Sizhou's army opened several tunnels to Puyang City, and then attacked Puyang City again.

Fortunately, Cao Cao had always been suspicious, and he soon responded. Later, he finally led more than 10000 disabled soldiers out of the encirclement and went straight to juancheng.

In the face of Cao Cao's breakthrough, Xu Rong did not order the army to pursue. Although the Sizhou army won, the soldiers were tired after a month's war. In addition, although Cao Cao was defeated, Xu Rong ordered the army to stop pursuing rationally.

Another point is that Cheng Yu's strategy is very successful. There are 12000 newly recruited soldiers in Puyang City, and nearly 8000 people died and wounded in the battle. Before entering the city, Xu Rong told Huangfu Chaobo about his speculation. After the capture of the city, Huangfu Chaobo ordered to screen out the nearly ten thousand captured soldiers. After careful inquiry, he finally confirmed Xu Rong's conjecture.

Finally, in desperation, Huangfu Chaobo had to order that the families of the soldiers who died in the battle be compensated according to the standard of the soldiers who died in the army of Sizhou. Only in this way can Puyang's people be slightly pacified.

However, this also made Huangfu Chaobo more afraid to catch up with Cao Cao's army. Later, after leaving Zhao yunbu in Puyang, Huangfu Chaobo and Xu Rong led the army to Chenliu. Now Chenliu's war is not over, and Cao Hong's 50000 troops are attacking Chenliu.

Because Chen Liu had only 30000 troops, Zao only negotiated with Chen Rong, Zhou Cang and Wang Ran and decided to stick to Chen Liu. As for the other counties, if they can keep the rules, they can only give up.

So Cao Hong's army conquered kaocheng, Jiwu, Xiangyi, waihuang and yongqiu in a month, and arrived outside Chenliu on October 12. Cao Ren left only a thousand soldiers to defend the cities he had captured. The rest of his troops, plus the troops he had collected from several cities, totaled 60000 troops. They arrived directly at Chen Liu city. He was ready to take Chen Liu down at one stroke.

With Puyang's lesson, Huangfu Chaobo had ordered Shi A's shadow guard to keep a close watch on Chen Liu. Sure enough, some people with bad intentions were dug out from the city, and then they were all directly executed by Zaozhi. For a time, Chen Liu had already killed his head before the war started.

After Cao Hong's army arrived at Chen Liu, they just took a day off and began to attack the city. Unfortunately, Chen Liu's well-equipped troops and solid city are far from the counties that Cao Hong attacked before.The two sides fought in the city for five days. Cao Hong lost thousands of troops, but he was unable to attack the city wall. However, although Cao Hong did not have tiger and leopard cavalry in his hands, he still had 2000 ordinary cavalry. When he attacked Chen Liu, Cao Hong did not forget to release his cavalry to explore the movements of the surrounding armies, especially the movements of the Sizhou army in Puyang.

Because of his caution, he saved tens of thousands of troops under his command.

When tens of thousands of troops of Huangfu Chaobo arrived in Xiaohuang county to the north of Chenliu, Cao Hong already got the news of the arrival of reinforcements. Seeing the sudden arrival of the troops of Huangfu Chaobo, Cao Hong had guessed that the battle in Puyang was over, so he led the troops to retreat overnight.

On the third day, Huangfu Chaobo, who arrived at Chenliu City, knew that Cao Hong's army had left. Immediately, he sent Tujia, Xiliang iron cavalry and Chenliu's ten thousand soldiers to pursue. He did not want to wipe out the enemy, but he had to recover all the cities under Chenliu's rule.

On November 2, Cao Hong's army retreated to Ningling, Wang Ran's army recovered all the lost cities under Chen Liu's rule, and the war in Yanzhou ended.

At this time, the war in Jizhou ended on October 22, the third day when Cao Cao lost Puyang City again. Yuan Shao left several generals to defend the cities of Taoguan and Quliang, and the army returned to the Bohai Sea.
