Li Mo is a double academic master in the Department of Modern History + Department of Biology. He is proficient in the history of the Qin Dynasty, basic medicine and simple engineering. He has a sober character and a sharp tongue, and occasionally makes mistakes. After traveling through time, he accidentally became an apprentice of an alchemist who was pardoned by Qin Shihuang. His original intention was to change the fate of the second generation of the Qin Dynasty who died, and by the way, help Ying Zheng survive, and ultimately promote the Qin Dynasty to sweep the world.
Qin Shihuang Yingzheng was able to condescend to useful people and have zero tolerance for useless people. Later on, he was gradually impressed by Li Mo's ability, but he always maintained the emperor's suspicion and majesty, and occasionally there were cute and funny moments of contrast.
