Cao Cao was also relieved that Liu Yu did not send troops. He had long expected that Liu Yu would not send troops, but there is always a case in everything, Liu Yu often does not play cards according to common sense, who knows if Liu Yu will lead troops to Yanzhou in anger.

After many inquiries and knowing that Liu Yu would not send troops but would hold the territory, Cao Cao finally put his mind at ease and was ready to develop his strength.

As Cao Cao thought, there is always a case in everything. Liu Yu didn't trouble Cao Cao, but someone else made trouble for him.

Cao Song died and was killed by Tao Qian.

Since Cao Song had a big quarrel with Cao Cao, he left his hometown angrily, regardless of Cao Cao, and traveled in the world.

Although Cao Song hates Cao Cao, a loser, Cao Song is a parent, even if there is a big contradiction, he will always care about Cao Cao's news. As Cao Cao's strength continued to expand, his official position became bigger and bigger, and Cao Song regretted that he had a big quarrel with Cao Cao at that time. And Cao Cao was also worried about his father's life, so he took the initiative to send people out to look for him.

Cao Cao's initiative allowed Cao Song to maintain his old face, and more importantly, he didn't have much money on him, so he came to Xuchang happily. The father and son also released their previous suspicions.

After staying in Xuchang for a while, Cao Song ignored Cao Cao's obstruction and began to travel the world again. Although Xuchang was stable, Cao Song felt a different life when he traveled before. Cao Song, who had been up and down in the sea for many years, felt that the first half of his life was in vain, so he decided to appreciate the beautiful scenery of the Han Dynasty in his later life.

Cao Cao is not very willing, his father is so old, if there is a good one, how can he explain it to his brothers and sisters.

Cao Song's attitude was resolute, and Cao Cao could only let him go, and arranged more guards around Cao Song to talk about his heart.

Traveling around the world costs money, and Cao Song has long run out of money, so he naturally stretched out his hand to the son of a big bureaucrat and a big landlord.

The corners of Cao Cao's mouth twitched, his father really didn't make people worry.

Cao Song got a huge amount of money from Cao Cao, and he was happy for the rest of his life.

In fact, Cao Song is worried about the lack of money, where to go in his capacity, can the local officials entertain, honor and stammer?

Cao Song finally discovered this problem, and scolded himself for being so old and confused, and even forgot the basic officialdom routines.

With these filial piety, Cao Song began to use it lavishly, and enjoyed it everywhere he went.

The local officials are all experts in the officialdom, and they are changing tricks to curry favor with Cao Song, hoping that Cao Song can say a few good words in front of his son Cao Cao. Cao Song also understood their hard work, and agreed with his mouth, as for whether this would cause trouble to Cao Cao, it was none of his business. The local officials were overjoyed, as long as they climbed the big tree of Cao Song, then they could soar.

In the future, when these local officials were arrested for committing crimes, they all claimed to be Cao Cao's disciples, which caused Cao Cao's reputation to deteriorate a lot.

I often walk by the river, how can I not get my shoes wet. Cao Song also met a sinister guy who led his life to an end.

Being touted by so many people along the way made Cao Song begin to become arrogant, and sometimes interfered in the internal affairs of other officials, pointing fingers, which was very annoying. But considering that Cao Song was the father of the great prince Cao Cao, and had a deep backing background, these officials could only endure it for the time being, and they were happy to serve Cao Song, and then they couldn't wait to send Cao Song out of the country.

Cao Song heard that Xuzhou is rich, the scenery is pleasant, and the characters are quite handsome, how can Cao Song, who is enjoying life, let go of this good place.

Knowing that Cao Song was coming, Xuzhou Thorn Shi Taoqian prepared a lot of gifts with his heart, and personally went out of the city to greet Cao Song, which can be said to have done a good job.

Cao Song's face was proud, as if he was an honor for Xuzhou to come to Xuzhou.

Tao Qian didn't care, held a grand reception banquet, and invited representatives of the Xuzhou context martial arts and family to participate, which gave Cao Song enough face.

Tao Qian's courtesy made Cao Song more and more arrogant, and after drinking a few glasses of wine, Cao Song began to sneer at Tao Qian, and even laughed at Tao Qian's incompetence in such a grand place. This made Tao Qian's face all lost.

Tao Qian is a Xuzhou assassin history, where can he endure such an insult. Tao Qian, who has always been known for being insidious, also endured it, and decided to find an opportunity to do Cao Song in his heart.

Tao Qian entertained Cao Song without changing his face, which made Cao Song even more arrogant.

After eating, drinking, and having fun in Xuzhou, Cao Song is ready to go to another place to enjoy life.

Tao Qian had already arranged an ambush on Cao Song's way. Cao Song didn't expect someone to kill him, so he fled to a toilet in a hurry to hide. Tao Qian gave a death order, did not kill Cao Song, and vowed not to give up. In the end, Cao Song was found by Tao Qian's people and killed in the toilet. Cao Song didn't know who killed him until the moment he died.

Tao Qian also did the finishing work and pushed things away. But Tao Qian forgot a sentence called Skynet, which is magnificent and negligent. Tao Qian's killing of Cao Song was still known, and it quickly spread to various places.

When Cao Cao heard the news, he was stunned for a while.

Cao Cao thought that his father would be kidnapped and blackmailed, but he didn't think that he would be killed, or he was killed by Tao Qian. Cao Cao's first reaction was that he had heard it wrong, and hurriedly sent people to find Cao Song. The men and horses sent out finally brought back Cao Song's body, and Cao Cao grieved to hold a funeral for Cao Song.

Cao Cao kept a vigil for Cao Song for seven days and seven nights, and the funeral ended. Cao Cao publicly announced that he would send troops to attack Tao Qian in Xuzhou to avenge his father. Most of Cao Cao's henchmen are from the Xiahou family and the Cao family, they are relatives of Cao Cao, and they are also sad and indignant about Cao Song's death. Xun Yu and other resourceful people wanted to dissuade Cao Cao, but they were stopped by Guo Jia.

"Wen Ruo, it's rare for the lord to have such a good excuse to expand the opportunity to expand his territory, do you still want to stop it?" Guo Jia could see a trace of excitement under Cao Cao's grief.

Guo Jia's words made Xun Yu and the others pause, and they finally understood Cao Cao's intentions. Xuzhou is so rich that it borders Yanzhou. If Xuzhou is captured, then the problem of insufficient grain production in Yanzhou can be greatly solved. This is very important to Cao Cao, who intends to dominate the world.

Cao Cao ordered the three armies to march towards Xuzhou. Before he was released, Cao Cao swore that he would definitely let Tao Qian know what the consequences of killing his father would be.

Cao Cao's three armies rushed straight to Xuzhou, and a major battle was inevitable.
