Why can Wargo destroy Shu with so few troops?

After Zhuge Liang's death, Wei attacked Shu, and Cao Wei's general Zhong Hui led150,000 elite to a deadlock with general Jiang Wei at Jianmenguan. Wargo and Zhuge Xu attacked Jiang Wei, but both failed. Wargo thought it was impossible to fight hard, so he thought of a dangerous way to sneak into a level playing field. At that time, Zhong Hui wanted to see his jokes and agreed.

From Yin Ping to Jiangyou, the mountain is inaccessible and very difficult. This year 10, Wargo led more than 10,000 troops and walked more than 300 kilometers from Yin Ping Road, digging mountain roads and building bridges and pavilions. When the mountains are high and the valleys are deep, it is extremely dangerous. And transporting food is dangerous. "In the face of difficulties, Wargo took the lead and encountered a crisis." Wrapped in a blanket, he pushed it down, and all the soldiers climbed the wooden cliff, filed in, climbed the path, cut the mountain to clear the way, and crossed more than 700 miles of uninhabited dangerous areas, "grain transportation is in danger." "Wei Jun overcame these unimaginable difficulties, finally passed the level tone and arrived in Jiangyou. The river is bounded by Shimen, close to Fucheng water, with a big river on one side and cliffs on three sides. It's a natural barrier as famous as Jiange, but the oil commander Ma Miao in Shujiang saw that Wei Jun was afraid of war and surrendered. Just ran away.

Wargo went straight into Fucheng. When Wargo bypassed Jinggu from level tone and entered Chengdu, Liu Chan already knew the news and ordered Commander-in-Chief Zhuge Zhan to lead the army to repel the enemy. Originally, Wargo's surprise attack plan here was bankrupt, because Huo Yi, the satrap of Nanjun County, heard that Wei Jun had smuggled level tone, and also wrote to Liu Chan, requesting approval to send troops to the north for support. Liu Chan thought that Zhuge Zhan's army had surpassed Wargo and it was entirely possible to defeat Wargo, so he refused to approve Huo Yi's request to lead reinforcements to the north, but Zhuge Zhan's army arrived. Business, advised Zhuge Zhan to move forward quickly, occupy it, don't let Wei Jun into the ground. Huang Chong persuaded him repeatedly, and even shed tears in pain, but Zhuge Zhan remained unmoved and stayed in Fucheng.

Wargo beat Zhuge Zhan striker. As soon as Zhuge Zhan heard that the striker was broken, he led the troops to retreat from the city gate for hundreds of miles and retreat to Mianzhu. And gave it to Wargo as a gift. After entering Mianzhu, Zhuge Zhan realized that he had made a big strategic mistake and sighed, "Except for Huang Hao, I won't be Jiang Wei, and I won't keep Jiangyou. I have three sins. Why should I face it? " The last battle was tens of thousands of corpses of the Shu army. Zhuge Zhan, Huang Chong, Shang Zun (the grandson of Zhang Fei) and Li Qiu, the right commander of Yulin, all died in battle. At this time, the latter listened to Qiao Zhou's advice and surrendered to Wei without waiting for Yan Yu's reinforcements. Wargo was going to lose this time, but he met Liu Chan and surrendered directly ~
