During the Three Kingdoms period, the three families of Wei, Shu and Wu stood on their feet, among which the national strength of Shu was the weakest. However, the ancestors of Shu have also been broad, at least at the peak, they have subdued Jingzhou and Yizhou, and the five tigers will be complete, but Guan Yu will lose the good situation as soon as he dies. After Guan Yu's death, Jingzhou was lost, Guan Ping was killed in battle, and Shu began to decline. In fact, the loss of Jingzhou was not the most fatal defeat, and it was only later that Liu Bei's fiasco at Yiling really brought Shu into the abyss of backwardness.
In the early stage of entrepreneurship, Liu Bei was bullied until he invited Zhuge Liang to assist, and later began to counterattack. In 221, Liu Bei officially ascended the throne and established the Shu regime. The first major thing Lao Liu did after taking the throne was to raise troops to attack Wu. At this time, due to the incomplete lineup of the five tiger generals, coupled with Ma Chao's desire to guard Yangping Pass, and Zhao Yun's opposition to sending troops, Liu Bei only brought Zhang Nan, Feng Xi and other non-mainstream generals to crusade against Sun Quan. These are not counted, Liu Bei has not yet brought the embodiment of wisdom, Zhuge Liang, to conquer Wu. The war was fought for more than 1 year.
In 222, due to the hot weather, Liu Bei had no choice but to lead more than 40,000 Shu soldiers to be stationed near streams and dense forests. At the same time, the camp of Shu was also placed 700 miles away. There were 50,000 defenders on the Wu side, and after a change of commander, Lu Xun became the commander of the Wu army. Lu Xun used to give people the impression that he was a little fresh meat, and he was also a scholar, without the slightest commanding temperament. But Lu Xun's IQ is very high, and this guy quickly found the code to crack Liu Bei's army: fire attack. In this way, Liu Bei's problem, which even famous generals such as Han Dang, Zhou Tai, and Pan Zhang could not solve, was easily resolved by Lu Xun.
There were several reasons for Liu Bei's fiasco. First of all, the Shu army only had 40,000, and the Wu soldiers had 50,000, and Liu Bei's troops were at a disadvantage. Secondly, the soldiers sent by Shu were all second-tier generals, and Zhao Yun, Ma Chao, and Wei Yan did not go to the front line. Another reason is that Zhuge Liang didn't go. Many people think that the most important reason why Liu Bei was hammered by Lu Xun is that Zhuge Liang did not go. So the question is: If Liu Bei really brought Zhuge Liang to go, would Shu be able to turn defeat into victory? If we look at it according to normal logic, if we don't say that Zhuge Liang abused Lu Xun 100 percent, at least the Shu soldiers would not be defeated miserably, and Lu Xun also admitted this point himself.
Lu Xun came up with a plan to attack the enemy with fire, and then said something like this: "I have this plan, but I can't hide it from Zhuge Liang'er." Luckily, this person is not here, so I have achieved a great success. In fact, Lu Xun's words have already given the answer: if Zhuge Liang goes, the Shu army will definitely not be defeated. It is not denied that Lu Xun is a good commander, but he is a star to death, and it is okay to abuse the diamond-level Liu Bei, but he also has no advantage in the face of the top king Zhuge Liang. Zhuge Liang is extremely intelligent, especially good at fire attack. Zhuge Liang is best at using fire to break the enemy, such as burning Bowangpo and burning rattan armor soldiers.
In addition, Zhuge Liang's military strategy is also very good. Ma Liang once showed Zhuge Liang the map of Liu Bei's station, and the latter immediately pointed out the drawbacks: fear of fire attack. This means that if Liu Bei had brought Zhuge Liang to go, the Shu army would not have camped for 700 miles, let alone stationed in a wooded place. In this way, Lu Xun can't use fire to break Shu. If Zhuge Liang goes to the front line, Shu will be invincible, and then if he uses his wits again, he will be expected to defeat Wu. It's a pity that history has no ifs, and Zhuge Liang failed to save Liu Bei's fiasco.
