Otaku in the Late Han Dynasty

Liu Zheng, a modern homebody, transmigrates to the late Eastern Han Dynasty and becomes a lowly auxiliary soldier of the Yellow Turban rebels. Drawing on his knowledge of history and modern military tactics, he survives the Battle of Changshe. He saves the fierce general Xu Huang, defeats Cao Cao, crushes Sun Jian, recruits Huang Zhong, and slays Zhu Jun. He invents the stirrup to shatter Hua Xiong’s cavalry. In the end, he launches a surprise attack on Luoyang, captures Emperor Ling and He Jin, and retreats safely with the crown prince, shaking the whole realm.
