At the end of the Eastern Han Dynasty, all the heroes came together, there were wolves everywhere, and there were swords and halberds in all directions. Since Cao Pi proclaimed himself emperor, Liu Bei of Shu also proclaimed himself king the following year, and Wu Sunquan founded the country. From then on, the Three Kingdoms were finally established. When later generations comment on this period of history, they are all called "heroes".
In the seventh year of the Jianxing of the Shu Han Dynasty and the second year of the Taihe period of the Cao Wei Dynasty, Zhuge Liang, then the prime minister of the Shu Han Dynasty, launched his third Northern Expedition. When the army arrived at Qi Valley, a group of troops harassed the enemy with guerrilla and surprise attack tactics, and assisted Han general Chen Shi to seize Wudu and Yinping counties. Kong Ming was also surprised. The following year, Cao Zhen, the governor of Cao Wei Guanyou, launched an offensive against Shu Han, but was attacked and restrained by a mysterious force in Ziwu Valley. The grain and grass were burned, and there was heavy rain. But Kong Ming didn't know that this group of troops who came and went without a trace was established by the Shu Han generals who selected the elite young Han people. They were named after the two generals Guan Yu and Zhang Fei who the emperor relied on most during his time, and after the ten ancient Tiangan "Yan Feng" and "Duan". "Meng", "You Zhao", "Qiang Wu", "Tu Wei", "Zhu Li", "Shang Heng", "Zhao Yang", "Heng Ai" and "Shang Zhang" selected ten outstanding warriors by order to form a powerful army - "Fei Yu".
