Cao Cao wanted to raise troops to come to Xuzhou in person to take revenge, but was persuaded by Xun Yu.

Xun Yu (yù) character Wenruo, Yingchuan Yingyin (now Xuchang, Henan) people. Cao Cao's chief strategist and outstanding strategist. Xun Yu is planning, conspiring, Kuang Bi, and has made many achievements, and is called "my son's room" by Cao Cao.

Xun Yu said: "Xuzhou is just a small piece of land in Gongsun Kang, even if it is fought out, it will not have much impact on him." But Cao Gong, you have such a little family background. Consume a little more, and it's unimaginable. You must know that there is more than one Xuzhou around us, and all the princes are eyeing us, and once they find that we are weak, they will inevitably pounce. Even Yuan Shao is no exception! You must know that when Cao Gong and Liu Bei fought over Yanzhou last year, Yuan Shao wanted Cao Gong to attach himself to him. ”

Cao Cao calmed down, no longer mentioned the words of revenge, and asked Xun Yu: "Wen Ruo, what should I do now?" ”

Xun Yu said to Cao Cao: "The Duke of Wen of the former Jin Dynasty accepted King Xiang of Zhou, and the princes Jing Cong; Gaozu went east to conquer the righteous emperor and returned to the heart of the world. Since the Son of Heaven Boyue, the general first advocated the volunteers, in order to disturb in Shandong, failed to go to the right of the Guan, but still dispatched the generals, the danger of the messenger, although the difficulty outside, but the heart is all in the royal family, is the general doctor of the world Su Zhi also. Is the car driving today? The righteous have the idea of saving the foundation, and the people feel old and mourn. Sincerity is therefore at this time, and the Lord is expected to obey the people, and the great shun is also; Bingzhi is impartial to serve the heroes, and the general is also; Fu Hongyi to be handsome, great virtue also. Although there are adverse festivals in the world, they must not be tired, and it is clear. Han Xian and Yang Fengqi dare to do harm! If it is determined from time to time, the Quartet will have hearts, and although they will think about it, they will not be able to do it. ("Three Kingdoms, Wei Shu, Xun Yu Biography").

Cao Cao believed that Xun Yu's words were reasonable, so he personally led a large army to Luoyang at the secret invitation of Dong Cheng, the general of Anji, and welcomed the emperor's relocation of the capital to Xu County (now Xuchangdong, Henan).

At the end of the Eastern Han Dynasty, the heroes rose together, Emperor Han Xian was embarrassed and migrated, 196 A.D. was the first year of Jian'an, Cao Cao specially welcomed him to his own territory Xuchang, on the surface it was to respect the imperial power, but in fact in the name of Emperor Han Xian to crusade against dissidents and appoint personnel, that is, "to order the Son of Heaven not to be a minister", or "to coerce the Son of Heaven to order the princes". Cao Cao, who proclaimed himself a great general, took advantage of this political advantage to rapidly expand his power.

Xinhai, Emperor Xian of the Han Dynasty named Cao Cao as the lieutenant of the school and recorded the affairs of Shangshu. Gengshen moved the capital to Xuchang. In November, Emperor Xian of the Han Dynasty named Cao Cao as the commonplace, and the riding generals were military, and the hundred officials always listened. Later, Cao Cao was named a general and the Marquis of Wuping.

In order to make the Han court in Xuchang authoritative, Cao Cao gave official positions to all the princes in the world.

Gongsun Kang was also named one: General Zhengdong.

General Zhengdong: General of the Heavy Horn, one of the four generals. The veteran is added as the "General of the Eastern Expedition".

During the time of Cao Wei, the official position was lower than that of the three dukes, and he commanded the four prefectures of Qing, Yan, Xu, and Yang, and was stationed in Yangzhou.

In other words: Cao Cao recognized Gongsun Kang's strength and confessed it. recognized Qingzhou and Xuzhou as Gongsun Kang's territory, and gave Yanzhou and Yangzhou to him.

Cao Cao has such a good heart? Of course not.

Cao Cao was a plan to drive the tiger and devour the wolf, and the general of Zhengdong was stationed in Yangzhou. That is to hope that Gongsun Kang will fight Yuan Shu, instead of coming to find trouble for himself. This is a conspiracy.

Cao Cao and Gongsun Kang were just gone, but they couldn't beat Gongsun Kang on the frontal battlefield, so they sent someone to assassinate him. Cao Cao played yin and sent two waves of men to assassinate Gongsun Kang.

Cao Cao didn't give them a time limit, just asked to be able to kill Gongsun Kang.

When he heard that Gongsun Kang was a beautiful woman, he sent a few beautiful women, and there were two female assassins hidden in them. Cao Cao ordered them to lurk first, and wait for a year and a half, Gongsun Kang lost his vigilance against them before they could act, it was best to use poison, and the assassination by force was no match for Gongsun Kang's martial bravery. Of course, if Gongsun Kang is asleep, it is okay to assassinate him again.

Gongsun Kang didn't understand Cao Cao's intentions, so he laughed at these beauties, and wondered if he heard that Cao Cao had several daughters who were also very beautiful, if the relationship eased, could he ask to marry one or two?

Fortunately, Gongsun Kang arranged these beauties in Qingzhou, instead of bringing them back to Liaodong. He himself was not afraid of being assassinated, but the women and children of his family were afraid.

In Liaodong, the servants of the Champion Hou Mansion are all born to three generations of families, and even the servants who Zhen Jiang married are not used. It can be seen that Gongsun Kang is cautious. Of course, Gongsun Kang, the maid who married Zhen Jiang, still smiled, because he was fortunate to have little time and was not pregnant, so Gongsun Kang did not accept him as a concubine. In the Champion Hou Mansion, there are still quite a few maids who have had zero contact with Gongsun Kang, and if they have a relationship, they will be accepted as concubines, and the number of his wives and concubines will be twice as many as now.

Therefore, none of the beauties sent by Cao Cao were accepted by him as concubines, but they were just counted as maids in the room. In fact, the main reason is: these beauties were selected by Cao Cao, and even Cao Cao was not tempted by women, will Gongsun Kang be tempted?

If Cao Cao is not lustful, if Cao Cao sends a woman who makes him happy, he may be accepted as a concubine by Gongsun Kang. In that case, even if you can't kill Gongsun Kang, infiltrate the mansion of the Liaodong Champion Hou, and kill Gongsun Kang's son or concubine, it is still possible.
