What should Shu do to unify the whole country during the Three Kingdoms period?

How does Shu unify the whole country? Words in the book: Wolong Feng Chu has a safe world, but there is still a word that many people may not know! Namely: filial piety at the beginning of the child, one person dies, it is difficult to prosper! Zi Chu refers to Liu Ba, and filial piety refers to Fazheng! So if two people are dead, is it difficult for the Han Dynasty to prosper?

First of all, let's take a look at how Zhuge Liang planned great events for Liu Bei in Longzhong Dui! Longzhong's suggestion: 1 Take the land of Jingzhou first. 2. The land of Yizhou is now Sichuan. As base areas, these two places will be profitable once the Central Plains changes! All the way from Jingzhou to Henan, all the way from Sichuan to the east into the Guanzhong area around Xi' an. It's also a big deal! In other words, the state of Wu at that time was not under Zhuge Liang's consideration at all! Zhuge Liang thought that Wu died after capturing the Central Plains! This is very reasonable, because after Wei destroyed Shu, Wu basically had no resistance!

However, Guan Yu was careless about Jingzhou, and Shu had to fight from west to east in order to go to the Central Plains. There is only one road without a military plan to go hand in hand with two roads! If Shu can hold Jingzhou, maybe Zhuge Liang can seize the Central Plains when he leaves Qishan six times!

Second, the defects of Zhuge Liang's long-term alliance With the fall of Jingzhou, the Central Plains changed dramatically: the emperor's Zen position was given to Cao Pi, and the Han Dynasty ended. Liu Bei Group is unstable in Shu, and there is no so-called "Han Dynasty"! People are distracted, and Shu has been rebellious! At this time, the role of Fazheng and Liu Ba is revealed! However, the death of Fazheng has brought more pressure to Liu Bei Group! So Zhuge Liang said: Yizhou is exhausted!

Third, Zhuge Liang was too cautious when fighting in Qishan. Since he realized that Yizhou was exhausted, he should go out and get Guanzhong! Send troops from Ziwuling! But he didn't!

The building can't jump straight! Longzhong is a classic plan, but things are impermanent and Zhuge Liang can't change it!
