Since Zhuge Liang came out of the mountains, in order to thank Liu Bei for his kindness, so he conscientiously contributed to the Shu state, after Liu Bei's death, he was also a single person to pick the beam and support Ah Dou to ascend to the throne, but unfortunately he planned seven Northern Expeditions and failed, and finally after his death, the Shu state died not long after. Zhuge Liang died in 234 AD, in Wuzhangyuan, in fact, before his death, he also made some arrangements for the Shu kingdom
During the reign of Liu Bei and Zhuge Liang, the Shu Han talents were abundant because they would employ people, and Jiang Huan, Fei Yi and others were all excavated during this period, but in the Liu Chan era, he favored eunuchs internally and could not restrain Jiang Wei externally, which made the national strength decline day by day. In fact, Zhuge Liang had quietly left behind a fierce general who could have prevented the demise of Shu Han, but Liu Chan abandoned it, and this person was Huo Yi.
He took Huo Yi with him, and also let him tour the military camp with his adopted son, grasp the situation of army building at the grass-roots level, and accumulate experience in leading soldiers. Therefore, when there was a rebellion in Yongchang in Nanzhong later, the imperial court sent him out to suppress the rebellion, and as a result, he beheaded the head of the thief in a battle. During the more than ten years that he defended Nanzhong, the local barbarians were all sincerely impressed by him, and there was no rebellion again, and his Nanzhong defenders were also one of the most elite troops of the Shu Han.
Liu Chan refused because Chengdu was well prepared, but in fact he still distrusted this fa xiao, fearing that he would bring troops into Beijing at this time to cause trouble. As a result, when Deng Ai led a surprise attack, the army was sent outside, and the defense of Chengdu was empty, frightening Liu Chan to surrender quickly. If Liu Chan could hold on to Chengdu and at the same time ask Huo Yi for help, Deng Ailao's expedition would inevitably be defeated and retreated, and the main force of Zhong Hui would be blocked in the Sword Pavilion, and Cao Wei could only return to Shu in vain, but unfortunately Liu Chan was just a soft egg!
