Li Xiangxi and Yu Xiaoli were scientific researchers in modern laboratories. Due to an accident, their souls traveled to Xiang Yu and Yu Ji in the parallel world. In the parallel world, they made up for the regrets of their previous lives and reproduced the series of events that the world thought would happen after Xiang Yu crossed the Wujiang River. Because they understood history and the original fate of the characters, they did not compete with Liu Bang for the world. Instead, they used modern skills to turn things around, leading the soldiers of the Central Plains to expand the territory and drive out the barbarians!
