Genshin Impact: My Baiqi Disciple's Chinese Historical Experience

I, Bai Qi, was originally an ordinary college student in China. I accidentally traveled to the Warring States Period in China and assisted the ancestors of the Qin Dynasty in sweeping the world.

A system came to Bai Qi's side, bringing with it the regret that the Teyvat people changed the history of China. Current heroines include Barnabas and Columbia
