Lin Yue traveled through the Qin Dynasty, but the system warned: every change will accumulate the cause and effect of destruction.
He gave technology to Qin Shihuang, helped the Han Dynasty destroy the Xiongnu, and helped the Tang Dynasty avoid war... He thought he was creating perfect history. Until that day, the changed "An-Shi Rebellion" broke out again in the Tang Dynasty, and the resentful spirits of the Six Kingdoms who died in vain revolted in the Qin Dynasty - history began a terrifying counterattack.
Lin Yue finally understood that his enemy was not the Huns or the rebels, but history itself! It is the "fate" that is destined to make China suffer!
To truly save China, what he must do is not to repair the past, but... To completely subvert it!
