After Guarding the Border for Years, I United the World

"Prince Dan, proceed to the northern desert at once and guard the frontier. Without an imperial decree, you may never return to Xianyang!"

Reborn into the Qin Dynasty, he is sent to the frontier from the start, where he unexpectedly activates the Hegemony System.

"Guard the frontier for one year and receive the Primordial Unity Inner Art!"

"Guard the frontier for three years and receive the Azure Dragon Spear and Xuanyuan Sword. With supreme power in hand, you can survey the realm!"

"Guard the frontier for five years and receive the Tiger and Leopard Cavalry and The Art of War!"

Eight years later, Qin Shi Huang dies, and the realm descends into chaos.

Just as the warlords storm Xianyang and the empire teeters on the brink of collapse, a golden spear bursts onto the scene, turning heaven and earth pale!
