Modern youth Lu Chen time-travels to the chaotic Dayu era, becoming the penniless young chieftain of the Black Wind Fortress, and activates the Hegemony Allusion System. He single-mindedly wants to save up enough wealth to run away to Jiangnan to retire, but is always dragged into dangerous missions issued by the system. Yet his subordinates interpret his every survival move as a far-reaching, grand strategy. Lu Chen is forced to gather troops, subdue martial arts factions, cleverly break the Taiping County official siege, and gets accidentally embroiled in the game of warlords. Clearly just wanting to lie flat and avoid disaster, step by step he is pushed onto the spotlight of contending in a chaotic world, embarking on a hilarious path to hegemony against his will.
