Origin Story
三国时期，魏国与蜀国为争夺汉中而发生激战。刘备与诸葛亮派老将黄忠去迎战曹兵被打败，赵云率军援救。曹操亲率大军追赶。赵云命士兵打开城门，偃旗息鼓，独自立在营前，曹操败退，刘备封赵云为一身是胆的虎威将军。
During the Three Kingdoms period, Wei and Shu clashed fiercely over control of Hanzhong. Liu Bei and Zhuge Liang sent the veteran General Huang Zhong to fight against Cao's forces, but they were defeated. Zhao Yun led his troops to the rescue. Cao Cao pursued with his army. Zhao Yun ordered his soldiers to open the gates of the fortress, lower the flags and silence the drums, and he stood alone before the camp. Cao Cao retreated and Liu Bei appointed Zhao Yun as the Tiger General, who was „full of courage.“
