After Sun Quan captured Jingzhou and killed Guan Yu's father and son, Liu Bei's anger was indescribable, and Guan Yu, who was extremely trusting and admiring, was beheaded by an unknown young general under Sun Quan's account.
If Sun Quan had killed Guan Yu in a brazen manner, it would have been enough, but when Guan Yu was fighting with Cao Cao's army and was unguarded, he secretly stabbed the most powerful knife from the back, attacked Jingzhou, and cut off Guan Yu's back road. Whether thinking about brotherhood or considering political interests, Liu Bei wanted to cut down Wu.
However, the Imperial Ceremony temporarily dragged liu Bei's impulsive pace. After the establishment of the Shu state, Liu Bei completely lifted the shackles, and at this moment, he made the most wrong decision in his life and poured the whole country's troops against Sun Quan.
Zhuge Liang first stood up and euphemistically expressed his opposition to Liu Bei. Zhuge Liang believed that although Sun Quan had taken Jingzhou, cao wei was strong and there would be no more moves to endanger the shu state. If Liu Bei now sent an army to fight against Sun Quan, he would fall into a fight and completely break Sun Liu's alliance, and if Cao Pi took the opportunity to attack the Shu state at this time, it would be too dangerous. However, Liu Bei made up his mind and firmly rejected Zhuge Liang's proposal.
Just when Liu Bei issued a military order, mobilized troops, prepared grain and grass, and was about to attack Eastern Wu. Another piece of news came that made Liu Bei's heart ache, and Zhang Fei was killed.
Zhang Fei is brave and good at fighting, and his majesty and might do not reduce Guan Yu, but in terms of personality, Zhang Fei is slightly different from Guan Yu. Guan Yu cared about the soldiers and disdained the soldiers; Zhang Fei respected the soldiers, but did not care about the soldiers. Liu Bei wanted to conquer Sun Quan, and he ordered Zhang Fei to lead 10,000 troops from Langzhong to join Liu Bei's army at Jiangzhou.
Before Zhang Fei sent his troops, he reprimanded the generals Zhang Da and Fan Qiang for trivial matters, and angrily said that he would be severely punished. Zhang Da and Fan Qiang, fearful of punishment, discussed privately and decided to kill Zhang Fei and surrender to Sun Quan. Therefore, when Zhang Fei was sleeping, the two men cut off Zhang Fei's head and went down the Yangtze River to ask Sun Quan for merit.
Zhang Fei's death seemed to have once again stabbed a knife in Liu Bei's heart. Although Zhang Fei was killed by his subordinates because of his tyranny and widowhood, Liu Bei, who was extremely angry, no longer considered this, and he calculated the account of killing Zhang Fei to Sun Quan.
In July of the first year (221) of the Shu Han Dynasty, Liu Bei almost did his best to command a large army to attack Sun Quan. Along the way, the army was endless, and Jiangdong was shaken.
Sun Quan did not want to fight Liu Bei, and he could see that Liu Bei was playing with his life this time. In Sun Quan's eyes, interests are the most important. He took Jingzhou because he was afraid of Guan Yu's prestige and fear that Liu Bei's power was too strong.
Now that Sun Quan had captured Jingzhou, he did not have to consider Liu Bei's threat for the time being, so he once again shifted his attention to Cao Wei. Sun Quan believed that compared with Liu Bei, Cao Pi was the most feared enemy. After much deliberation, Sun Quan decided that this unnecessary war with Liu Bei should be avoided as much as possible!
In Eastern Wu, Zhuge Liang's brother Zhuge Jin held a heavy position and was very familiar with Liu Bei. Sending an emissary of peace, Zhuge Jin was the most suitable. Zhuge Jin regarded Liu Bei as a wise man and played a set of choice tricks with Liu Bei.
The letter reads, Liu Bei, you should not neglect the great righteousness of revitalizing the Han Dynasty because you are concerned about your feelings with Guan Yu, you should inherit the banner of the former emperor, do not dispute with Sun Quan for the sake of Jingzhou's small profits, and ignore the great cause of the world. Moreover, even if you regard Sun Quan as an unforgivable enemy, where should your first enemy, Cao Wei, be placed?
However, the two ai generals were killed, Jingzhou was taken, and Liu Bei, who was extremely angry, did not eat his set at all, and completely ignored it. Sun Quan's several requests for peace were rejected, and he had to prepare for a big battle with Liu Bei. Since war was inevitable, Sun Quan began to plan how to reduce casualties and increase the probability of victory.
Fearing that Cao Pi would send troops from Hefei to the south to take Shukou when Liu Bei attacked Jingzhou, thus falling into the dilemma of a two-front battle, Sun Quan, after careful consideration, disregarded his own identity and asked the younger Cao Pi to surrender.
In August of the second year of The Reign of Wei Huang (221), Sun Quan sent emissaries to Wei as vassals and returned the soldiers who had been captured. The courtiers were very happy. Cao Pi believed that Sun Quan had surrendered to him from afar, and if he went to fight him, it would make the people in the world who were willing to submit to the State of Wei suspicious, so he crowned Sun Quan as the King of Wu.
Liu Bei led a large army to march into Shensu, and the Area of Wu County and Mogui occupied by Sun Quan was also on high alert. In the end, the famous "Battle of Yiling" in the Three Kingdoms period ended with the defeat of the Shu soldiers.
