In the autumn of the fourth year of the first peace, when Yuan Yao led his troops into Chenyang, there was also a storm breaking out on the land of the Central Plains, which swept almost all the princes of the Central Plains.

Last year, Chen Liutai guarded Zhang Miao and Jibei Prime Minister Bao Xin ambushed Chen Zhi, a general under Yuan Shu, and then the Yellow Turban of Montenegro invaded Yanzhou, killed Liu Dai, the assassin of Yanzhou, and planted the Yellow Turban battle flag almost all over Yanzhou. At the critical moment, Cao Cao stood up and single-handedly solved the Yellow Turban bandits in Montenegro, and even captured more than 100,000 Yellow Turbans in Montenegro and subdued Zhang Yan, the leader of the Yellow Turbans in Montenegro. Later, Cao Cao was jointly recommended by Wan Qian and others in the former Yanzhou Zhizhong as the assassin of Yanzhou, and only waited for the appointment edict of Chang'an to come down.

Cao Cao also fought a turnaround battle from this, occupying most of Yanzhou, only Yongqiu was occupied by Chen Zhi, and it could not be recovered for a while. However, Cao Cao's strength has also improved by leaps and bounds, with an army of 100,000 and 1,000 fierce generals.

After Cao Cao occupied Yanzhou and became a world-famous prince, Cao Cao's father, Cao Song, who had taken refuge in Langya due to the war, took his young son Cao De to Yanzhou.

Cao Song is the father of Cao Cao and the adopted son of Cao Teng, who often served Cao Teng during the period of Emperor Huan.

At the end of Emperor Huan, Cao Song was subordinate to the school because of Cao Teng's relationship and his own decent treatment of others. After Emperor Ling succeeded to the throne, Cao Song successively served as an important official position of Da Honglu and Da Si Nong, and Cao Song was not an honest person like Cao Teng, he had been an official for many years, and because of his power and profit, the Cao family could be said to be a rich party.

In the fourth year of Zhongping, Taiwei Cui Lie was dismissed, and Cao Song, who was the great Si Nong at that time, bribed the lieutenant and donated 100 million yuan to Xiyuan, and was given the position of Taiwei and ranked as the third duke. However, Cao Song's lieutenant was dismissed after only half a year, and then Cao Song returned to his hometown in Qian County.

During Dong Zhuo's rebellion, Cao Cao stayed in Chen's cavalry, and Cao Song helped him with his family wealth, but he was afraid of the sword soldiers on the battlefield, so he took his young son Cao De to take refuge in Langya County, Xuzhou.

And Xuzhou Thorn Shi Taoqian also saw Cao Cao's development, and felt that Cao Cao was not a simple person, and one day he would be trapped in the dragon and ascend to heaven, so he wanted to marry Cao Cao and seek a way out for his heirs. At this time, Cao Song was going to Yanzhou, passing by Xiapi, Tao Qian welcomed Cao Song to Xiapi City, and treated him with good wine and food every day, in order to let Cao Song be able to read his own good, so as to achieve the purpose of befriending Cao Cao.

I have to say that Tao Qian's strategy is still very effective, and Cao Song also thinks that Tao Qian is a good person, and plans to say a few words to him in front of Cao Cao, anyway, it is a convenient thing.

When Cao Song was leaving, Tao Qian arranged for his subordinate Zhang to lead 500 elite soldiers to guard, Zhang was originally the Yellow Turban Yu Party, and Tao Qian surrendered later, but the thief nature has not changed, on the way to protect Cao Song, coveted Cao Song's belongings, and because he was despised by Cao Song along the way, he was resentful, so, in a sudden heavy rain, Zhang took his own leaders to kill Cao Song's family, set fire to the temple where they stayed, and then went to Huainan to seek refuge in Yuan Shu.

Zhang Lai took refuge in Yuan Shu, and did not directly find Yuan Shu, but found He Man, Liu Pi, Gong Du and others under Yuan Shu, and He Man and others also kept Zhang Yu because Zhang was once a yellow scarf, and prepared to recommend it to Yuan Shu at a later date. Of course, Zhang did not say that he killed Cao Song's family, because once this matter was revealed, Liu Pi and Gong Du would not let him go.

On the other hand, Cao Cao had already received the news that Cao Song was coming, but when the calculated time came, there was still no trace of Cao Song and his party, and even after not meeting a person who came to report the news, Cao Cao felt uneasy and hurriedly sent someone to find Cao Song and his party.

After Cao Cao learned of Cao Song's death, he was furious, regardless of the dissuasion of his subordinates Xun, Manzhong and others, and led 80,000 troops to Xuzhou, so that Xuzhou would accompany Cao Song to bury.

Cao Cao didn't know that Zhang killed Cao Song because he was greedy for money, and he didn't know that Tao Qian wanted to befriend him, what he knew was that Tao Qian's subordinate Zhang killed his father Cao Song, and it must have been Tao Qian's instigation behind his back.

If Cao Cao was the only one who was angry, then Xun, Xi Zhong and others might be able to persuade him to come back, but in addition to Cao Cao, Cao Ren, Cao Hong, Xiahou Yuan, Xiahou and other Cao Cao's family generals were all furious, so that Xi Zhong and others could not be persuaded to come back at all. can only watch Cao Cao raise an army of 80,000, with Cao Ren, Cao Hong, Xiahou, Xiahou Yuan and others as the vanguard first, and he took Dian Jie, Dian Wei, Le Jin, Fang Yue and others behind, Xi Zhong, Cheng Yu, Chen Qun and others as military advisors, Xun, Man Chong, Mao, Han Hao and others stayed in Yanzhou.

Cao Cao was angry with 80,000 troops because of Cao Song's death, and the news of Xuzhou was naturally not hidden from the several princes around him, and it didn't take long for Yuan Shao, Liu Bei, Gongsun Zhan, Yuan Shu and others to get the news, and after getting the news, the reactions of the major princes were different.

After Yuan Shu knew that Zhang, who had killed Tao Qian, had escaped to his command, he immediately ordered someone to find Zhang, and then ordered someone to send Zhang's head to Cao Cao with a knife.

Yuan Shu and Cao Cao are also quite friendly, and Yuan Shu is most unaccustomed to a thief like Zhang, so he will naturally not show mercy, as for Liu Bi, Gong Du, and He Man, who took in Zhang, they were all implicated because of this matter, and were demoted and punished by Yuan Shu.

Of course, Zhang's head was sent away, but the property that Zhang looted that originally belonged to Cao Song was left by Yuan Shu, and it is already worthy of our friendship to solve the murderer for you, as for the stolen goods or something, then I will stay, and I Yuan Shu also needs to be paid for killing people.

When Zhang's head was sent to Cao Cao, it did not calm Cao Cao's anger, and Cao Cao had already invaded Xuzhou at this time, and the messenger sent by Tao Qian was directly killed on the spot, or fried, without showing the slightest idea of reconciliation.

You sent someone to kill my father, and you still want to reconcile with me, do you think I'm Cao Cao so easy to bully? If I don't slaughter Xuzhou this time, my Cao Cao will not be surnamed Cao, and your surname will be Tao.

With such thoughts, Cao Cao ignored the messengers sent by Tao Qian or other Chen Gong and others who came to persuade Cao Cao, no matter what they said, Cao Cao's army did not stop marching, and fought all the way into Xuzhou.

Cao Cao's move also angered Chen Gong and made Chen Gong go directly.
