Mr. Shui Jing once said: Wolong Fengchi can get the world, Liu Bei can get both, but unfortunately Fengchi died in Luofengpo when he led the army to capture Xichuan, leaving Zhuge Liang to bow down and die, and then he died of illness. If Liu Bei could unify the Three Kingdoms without dying, the answer was impossible.
Zhuge Liang
In ancient times, the strong standards of a country or prince depended on many factors such as land, city, population, weapons, army, and military generals. If the phoenix did not die, zhuge Liang, who was logical, would not have left Jingzhou, Guan Yu would not have carelessly lost Jingzhou and defeated Maicheng and was beheaded, Zhang Fei would not have eagerly avenged the beating of the soldiers and had their heads cut off, and Liu Bei would not have led his troops to attack Eastern Wu and died of illness by Lu Xun's burning camp. As a result, Liu Bei sat in Jingzhou, Xichuan, Hanzhong, and other places, and his ministers included Zhuge Liang, Pang Tong, Ma Liang, and others, the military generals Xiang Yu, Zhang Fei, Zhao Yun, Ma Chao, Huang Zhong, Wei Yan, Li Yan, and later Xiu Zhiping, Zhang Shao, Zhang Nan, Feng Xi, and Ma Dai. At this time, Zhuge Lianglong's pair was basically satisfied: first go to Jingzhou, then take Xichuan, Xihe ethnic minorities, Nan and Sun Quan, wait for the world to change Jingzhou and Yizhou jointly send troops and can recover the world, even so Liu Bei is also difficult to take the world.

In terms of land population: although it has Jingzhou, Yizhou, Hanzhong and other places, it is still at the bottom of Sun Quan and Cao Cao at that time, and the total population is about 1.3 million, and the gap between Sun Quan's population of about 2.4 million and Cao Cao's population is too large; in terms of talent training: In addition to the above figures, the few people in Shu Han are too withered for Eastern Wu and Cao Wei talents.

According to Longzhong's countermeasures, the world can only send troops to cut down Wei and will not cut down Wu, because of the geographical location occupied by Liu Bei, if Wu relies on jingzhou strength, it still needs Yizhou troops, so that Yizhou is empty Cao Wei will definitely sneak attack, so it can only cut Down Cao Wei, and the reason why The eastern Wu should know and will not sit idly by while shu Han destroys Cao Wei is not good for itself; so it will send troops to play a balancing role, so that the three kingdoms will be in a full situation; and after many years, Zhuge Liang and a large number of talents will die, and Shu Han talents will still be destroyed. Therefore, Liu Bei could not unify the world.
