Cao Cao didn't dare to recuperate, Youzhou couldn't be his sad edge, he had to take Youzhou first before he could go all out to deal with Zhang Yi. Now that Zhang Yi is not moving, he must take Youzhou before Zhang Yi moves his troops again, and then develop while defending Zhang Yi.

Cao Cao was much weaker than the same period in history, and at this time in the same period of history, he had not only taken Youzhou, but also driven Yuan Shang and Yuan Xi to Liaodong. Not only that, but he also occupied the entire Xuzhou, as well as Huainan and other places. Moreover, Cao Cao had a very large army, and it can be said that the historical Cao Cao was at least half stronger than the current Cao Cao. From the perspective of talents, Cao Cao has lost too many talents, Xiahoudun, Liu Ye, Hua Xin, Wang Lang and others are all under Cao Cao's rule.

Cao Cao has a characteristic, that is, the more difficult the time, the stronger the resilience. At this time, he showed such a side, in June of the twelfth year of Jian'an, that is, not long after Zhang Yi returned to Shouchun, Cao Cao went north to Jizhou and began to prepare for the attack on Youzhou.

When he arrived in Jizhou and joined Zhang Liao, he gave Zhang He an order to attack Dai County from Bingzhou, he himself led troops to attack Zhuo County and Shanggu County, and Zhang Liao attacked Guangyang County and Yuyang County from Bohai County.

Yuan Shang and Yuan Xi hoarded an army of 30,000 in Fanyang in Zhuo County, and let Wuhuan soldiers and horses be in Gu'an County. When Cao Cao went north to Zhuo County, he directly attacked Beixincheng and looked across the Fan River from Fan Yang.

Confronting Yuan Shang and Yuan Xi across the river, Cao Cao asked his advisor Guo Jia: "Now that Yuan Shang is in Fanyang and Wuhuan is by his side, what should I do?" ”

Guo Jia chuckled and said, "The lord already has a plan, why do you want to ask Jia again?" ”

Cao Cao said: "It is said that heroes see the same thing, and if there is someone who thinks the same as me, I can rest assured." ”

Guo Jia shook his head, "Even if the right thing is definitely done by yourself, you must do it, and even if you don't do the wrong thing, even if you don't want to do it." ”

Cao Cao didn't think so, "If no one agrees, wouldn't life be boring?" ”

Guo Jia smiled and didn't continue, but looked in the direction of Fan Yang and said: "Yuan Shang and Yuan Xi are just unscrupulous, although Wuhuan is difficult to deal with, as long as you find the lifeline, you can completely break it with one blow." ”

Cao Cao asked curiously, "Fengxiao, does this have an idea?" ”

Guo Jia said: "Wuhuan is difficult to deal with mainly because it comes and goes freely, and even if it is defeated, it will soon come back." But as long as he finds him where their royal court is, and takes down their royal court, narrow the old and young, Wuhuan can be pacified. ”

When Cao Cao heard this, he was overjoyed, if he could really win his royal court, he could really do it once and for all. But before that, Cao Cao now needs to find the location of the royal court, otherwise, where will he attack?

"After ordering Zhang Liao to conquer Guangyang and Yuyang, look for someone who can find the Xiongnu royal court!"

"Order Zhang He to march east immediately after capturing Daijun, outflank Gu'an and Fanyang, and encircle and suppress Yuan Shang and Yuan Xi with me."

Cao Cao issued two orders in a row, and began to mobilize the army, attracting the attention of Yuan Shang, Yuan Xi and Wu Huan, and creating opportunities for Zhang He.

After Zhang He entered Dai County from Bingzhou, he directly attacked Beipingyi from Banshi County to the northwest, and then went north to Gaoliu, the seat of Dai County. After taking Gaoliu, Zhang He sent a partial division north to Macheng, and he himself went south to the Taoist and the Shan clan. Because he received Cao Cao's order, he needed to go directly south to Pingshu, to Guangchang, Jizhou, and then cross the Great Wall to the source of Yishui.

When he was in Pingshu, he once again sent a partial division to attack Dong'anyang, Daixian, Dangcheng, and Sanggan.

Zhang He went directly from Yishui to Gu'an, and Wuhuan didn't expect that there was an enemy in this direction. Zhang He suddenly killed, and Wuhuan was caught off guard.

Wuhuan is generally active in the three counties of Youbeiping, Liaoxi, and Liaodong, but it is headed by Liaoxi Badun. The relationship between Badun and the Yuan clan is very good, so this time Badun also came with troops. He has been Wuhuan Shan Yu for nine years, because he is not the son of the previous Wuhuan Shan Yu Qiu Liju, but just a slave. However, when Qiu Liju died, his son Lou Ban was still young, so he took power on his behalf.

It was during this period that Yuan Shao sealed the leaders of the Wuhuan of the four counties and counties, Bundun, Nanlou, Sumuyan, and Wuyan as Shan Yu, and it was also at this time that he recognized the status of Bun Dun Shan Yu. Although Wuhuan of the three counties later served Lou Ban as Shan Yu, this feeling Wuhuan has always remembered.

This time, Bang Dun brought the Wuhuan Nanlou in Shanggu and Wuhuan Wuyan in Youbeiping, and gathered more than 10,000 Wuhuan soldiers.

Even though Wuhuan was a soldier, he did not have any military discipline, and he was shocked by Zhang He and dispersed in a hurry. Some were frightened, while others wanted to get away from Zhang He's attack first and then gather. Zhang He saw Wuhuan scattering and fleeing, and immediately led his troops to pursue, Zhang He also had cavalry under his command, so he directly brought the cavalry to pursue.

As a result, Wuhuan changed from a fake defeat to a real defeat, and retreated through Zhuo County before escaping from Zhang He's pursuit. Zhang He gained a lot in this battle, killing more than 1,000 Wuhuan people and obtaining more than 2,000 war horses.

After defeating Wu Huan, Zhang He immediately turned back to Fan Yang.

Fan Yang Yuan Shang and Yuan Xi also knew about the defeat of the Wuhuan army, and the defeat of Wuhuan affected the morale of the army, and the two brothers decided to retreat after discussion.

But Cao Cao knew before them that he arrived in Fanyang County first. Just in time for the Yuan brothers to withdraw their troops, Cao Cao directly waved his army to pursue, so it was another retreat and a losing battle. The Yuan brothers had no experience in escaping from Wu Huan, and before they arrived in Zhuo County, they were defeated by Cao Cao. The two brothers took only about 1,000 cavalry and went north to the upper valley.

But when they passed through the vicinity of Guangyang County, they found that there were also Cao troops in the Guangyang area. When they arrived at the upper valley, they got together with Nanlou. When Nanlou learned that Cao Bing had appeared in Guangyang, he immediately told the Yuan brothers that he was not safe here, and asked them to go to Badun, the western part of Liaoning was remote, and Cao Cao could not attack it at all. When the Yuan brothers heard this, they felt that it was very reasonable, and immediately bid farewell to the difficult building and marched towards Liaoxi.

After Cao Cao and Zhang He's troops were united, they directly attacked Xiazhuo County, and then sent troops to attack Fangcheng in the east, Yanguo in the west, and Liangxiang in the north.

Zhuo County was all taken down, and Cao Cao set his sights on Shanggu County again. The Yuan clan has been defeated, and the biggest threat to Shanggu is no longer the defenders there, but the Wuhuan Nanlou Department located in Shanggu.

Cao Cao didn't stay long in Zhuo County, went directly north to Shanggu, went directly to the county to rule Fuyang, and then sent troops to attack Nanlou. Nanlou was defeated in Gu'an, and his vitality was already greatly damaged, how can he still be Cao Cao's opponent? After the First World War, he suffered heavy injuries and had to go east and follow the Yuan brothers to seek refuge in Shan Yu's royal court.
