Former international law enforcement officer Qiao Yibai, in order to trace the whereabouts of his missing sister, mistakenly enters the Hall of Ten Thousand Traces after touching an antique with his childhood friend Xie Ren. Every antique in the hall transforms into a dungeon; losers will completely dissipate, and even friends and family will forget their existence. The two meet veteran player Qin Yueru and are about to open six major civilization dungeons. The first season involves consecutively clearing two major civilization dungeons from the Republic-era theater to the Northern Wei palace, relying on dismantling rule loopholes to pass levels again and again. As the level-clearing deepens, the reincarnation background and the ultimate truth of the Hall of Ten Thousand Traces are slowly unveiled. This journey to find his sister ultimately becomes a redemption spanning reincarnations. The six-generation intertwined romantic fate of Qiao Yibai and Qiao Qing, and their sacrifices for the country and home, are all within the dungeon stories.
