The first emperor in history to unify China, Qin Shi Huang, has passed away, and the world is in turmoil, with various heroes fighting to be his successor.

"High status does not depend on birth; every man can achieve great power if he exerts himself"

These words were not only the words of a great and noble man but also the words of many ambitious people who were beginning to rise to the occasion. And in a secluded hermitage, Sima Qian, an "Alternate History Manager Apprentice," begins to dream. The world of man is in turmoil, swallowed by a black wave, and everything is collapsing. Unable to overlook the collapse of the alternate history that is heading to destruction, Sima Qian breaks the rule of the Immortal Realm and descends into the mortal world. And in that mortal world, where Sima Qian descended, two dazzling stars appeared. Xiang Yu and Liu Bang. The era of the two people, later known as the "Red Dragon Maiden" and the "Wicked King" begins.
