Great Qin: What If Li Chengqian Became Fusu

#History: The Protagonist Is Reborn as Fusu

I think it was a quick transmigration story. The protagonist became young Fusu and worked with the First Emperor to make the Qin dynasty better and better. They were especially close, and the First Emperor supported everything he did. I think Hu Hai was executed by the First Emperor after his true nature was exposed. In the end, he was buried alongside the First Emperor.
