I Built the Imperial Tomb at the Beginning, and I Became the King of Scrolls in the Qin Dynasty.

A modern migrant worker accidentally traveled across the Qin Dynasty. Possessing full-level modern skills, he counterattacked step by step from the bottom and became a close associate of the First Emperor. He entered Lishan Mountain, presided over the construction of the Qin Emperor's Mausoleum, and revealed the eternal secrets deep in the underground palace. Everyone sighs that the Qin Mausoleum is mysterious and unpredictable, but they don't know the real secret. It's all up to me - the secret keeper of Qin Ling.
