In Shu Meng 243, the Chu king Qiu Xiu wanted to destroy the State of Wei, and the Shu Han Emperor Wei Huan captured the Yue minister He Zhi.
On August 1, 277 AD, the news of the collapse of the Wushu alliance had spread throughout the north and south of the great river, and some people were happy and some were sad. In Shouchun, the seat of Yangzhou, after reading the information book, Yangzhou Mu Chu Wang Yi Qiu Xiu said to his generals and staff: I did not expect Shu Han to abandon the Wu-Shu alliance so decisively, it seems that Shu Han's determination to unify the world is very great, although the lone king has declared himself a vassal to Shu Han, Shu Han also accepted us and also named me the King of Chu. However, we are still in the land of bullets, there are many crises, the lone king wants to fight against Cao Wei, but the State of Wu and the State of Yue are looking at us with a tiger's eye, although we are subordinates of Shu Han, but we have difficulties, Shu Han must sit idly by, it is impossible to send troops to help us, it will only make us fend for ourselves.
His chief of staff said to Qiu Xiu, the king of Chu: The Great King is wise, Shu Han will certainly not care about us, as for the Great King saying that he wants to attack the State of Wei, he thinks it is inappropriate, first, our army is only 50,000 soldiers and horses, unable to cut down Wei, second, the Shu Han army has gone south, the morale of the Shu army is as high as a rainbow, the morale of the Wei army is as low as water, and the 150,000 Wei troops in Picheng, Xuzhou, are just dying and struggling, and the Shu army will definitely win. Other subordinates of Yuqiu Xiu also agreed. Qiu Xiu, the king of Chu, could only say: Then strengthen the defense of Shouchun, the Vietnamese army, the Wu army, including the Shu army, are all looking at us. Yu Qiuxiu thought in his heart, will it be a road of no return that he declared independence this time and established himself as king? Just like the big brother started the army, and finally the soldiers were defeated and killed?
On the other hand, the Shu Han army had recovered from the chaos, reorganized the army, and under the command of the Shu Han general Wen Duan, continued to march south and attack Xia Pi.
Another Shu army, led by Shu Han's chancellor Wei Wan, attacked Xiao Pei of the Yue state on the way and captured the Yue minister He Zhi.
