Transcending to Great Qin: From Attendant to World Sovereign

Transmigrated into a minor attendant of the Qin Dynasty, originally wanting to slack off and coast through life. Unexpectedly, the First Emperor chases me for firearms, cement, steam engines, and even forces twelve stunning beauties on me as 'business partners'? Harem intrigue? Not a thing. These twelve sisters are more competitive than each other: one turns the penal system into a chancellor, another becomes the richest through military industry, and yet another sweeps across Eurasia with iron cavalry... A century later, the Roman Empire tearfully sues for peace, and black dragon flags are planted worldwide. The First Emperor hugs my shoulder and laughs: 'My dear minister, my fate is in your hands!' — Forcing the tyrannical Qin to endure for ten thousand generations, I am reluctantly made the world sovereign. Annoying.
