If Liu Bei wins the battle of Yiling, can he defeat Cao Cao to unify the Three Kingdoms if he wins Soochow?

Anyone who has seen "The Romance of the Three Kingdoms" knows that although the decline of the Shu Han began with the death of Guan Yu, the strength of the Shu Han was gone forever. It was due to anger and loss of reason. He wanted to avenge his younger brother. Liu Bei attacked Soochow but was defeated by Yiling. But if Lu Xun did not stop Liu Bei's attack in the Yiling battle, would history be rewritten? The answer is no, and it depends on our specific analysis.

Yiling War

First the Yiling War broke out. The fuse was the death of Guan Yu. The Shu Han lost not only a famous general, but also related Feather stationed in Jingzhou. Therefore, when Liu Bei borrowed Jingzhou from Jingzhou, he did not repay it. In the end, the retribution fell on Guan Yu, because Guan Yu was famous in the battle of Xiangfan, and at the same time he gave Sun Quan a huge deterrent, so that Dong Wu and Cao Wei secretly colluded. Together. Liu Bei led the 50,000 Shu army to attack Soochow. In fact, the main goal was Jingzhou. After all, Jingzhou, as a strategically important place connecting the north and the south, has been watched by all forces.

If Liu Bei defeats Lu Xun in the Battle of Yiling and wins, the dominance on the battlefield will be in the hands of Shu Han, and at least Jingzhou, which was lost due to the death of Guan Yu, can immediately return Shuhan. But if you want to annex Dongwu, you can't do it with the battle of Yiling alone. Even if the 50,000 Shu army is unharmed, you can't do it. At most, you can only let Sun Quan give more benefits to the Shu Han. After all, to win Yiling, you have to win Jiangling to be considered to win Jingzhou. To overthrow Sun Quan with this is simply nonsense.

As long as the Soochow can not be solved quickly, the Shu Han will always choose to form an alliance with Soochow and fight against Cao Wei together. Because Cao Wei had unified the north for many years, after Cao Cao’s death, Cao Pi came to power. He did not initiate a major war like the Battle of Chibi like Cao Cao. He also adopted a policy of rest and recuperation, which made Cao Wei, who has the most population and food production areas, and Dongwu, The power gap between the Shu Han is getting bigger and bigger. Therefore, even if Liu Bei was defeated in the battle of Yiling, Lu Xun was chased to Baidi City, and Baidi City died of illness. When Zhuge Liang presided over the diplomatic work of the Shu Han Dynasty, he still chose to repair relations with Soochow.

Because regardless of the victory or defeat of Yiling, the biggest threat to the Shu Han is still the northern Cao Wei. In the end, he will choose to form an alliance with Dongwu to fight against Cao Wei. After all, Cao Pi is still very happy to watch. When the two competed, he unified the world at the least cost. It was the general trend that Cao and Wei ruled the world, and the biggest problem of the Shu Han was the problem of population, food, and economy, which could not be solved by winning the battle of Yiling. Therefore, even if Liu Bei defeated Lu Xun, history would still be difficult to rewrite.
