Da Qin: Gongzi Dan, Guarding the Border for Eight Years

"Gongzi Dan, go to Mobei immediately and guard the frontier. Without the will, you will not be allowed to return to Xianyang for the rest of your life!" He had just been reborn in Da Qin and was sent to the frontier at the beginning, accidentally activating the hegemony system. "Guarding the border for one year will reward Hunyuan's inner strength!" "Guarding the border for three years will reward the Qinglong Spear, Xuanyuan Sword, and the Supreme Being in hand, peeking into the world!" "Guarding the border for five years will reward Tiger and Leopard Cavalry, Sun Tzu's Art of War!"... Eight years later, Qin Shihuang died, and the world was in chaos. Just when the princes from all walks of life were marching through Xianyang and the building was about to collapse, a golden gun appeared from the sky, and the color of the world changed!
