I'm Really Not Lao Ai

Zhao Jiu, a history teacher, transmigrated into the body of Ying Jiu, a down-and-out member of the Qin royal family in the eighth year of King Zheng's reign. He soon realized something that could cost him his life: he was the very same "Lao Ai" who, according to the history books, was made Marquis Changxin, torn apart by chariots in the public square, and had his three clans exterminated. The name "Lao Ai" was a slur invented by historians. If he failed, the history books would call him Lao Ai. If he succeeded, they would record just one line: King Jiu of Qin took the throne. Claim the throne, destroy the six states, conquer the Xiongnu and the Western Regions, and unify the world. The title of Emperor of the Ages belongs only to Qin Shi Huang, Ying Jiu.
