Li Nian, a Three Kingdoms enthusiast from the 21st century, has his soul transported to the late Han dynasty and becomes the son of Li Chun, the Governor of Yuzhang. His awakened "System of Chaos Across a Hundred Dynasties" tears through time and space, bringing emperors such as Qin Shi Huang, Li Shimin, and Genghis Khan, along with their famous ministers and mighty generals, into the Three Kingdoms era. The heroes of a thousand years of Chinese history gather, igniting an ultimate war of chaos. As the young master of an influential Jiangdong clan, Li Nian must wage campaigns and earn merit amid the competing powers of Cao Cao, Liu Bei, and Sun Quan before he can summon a team of his own from across the ages. As Bai Qi faces Lü Bu and Zhuge Liang clashes with Wang Yangming, he learns from history and uses the System to maneuver across the land. In this battle spanning a thousand years, he forges a path to unifying the realm that belongs to Li Nian alone.
