I Help the First Emperor Unify the World

Interstellar maiden Weisheng Xue unexpectedly binds to a system and transmigrates to a cultivation world. The system says that sword cultivators here can shatter stars with a single strike, pháp cultivators can lock up恆星 with a single talisman, and curse masters can sever life and death with a single word. Weisheng Xue thinks, "I understand, staying alive is important, I'll go into seclusion to cultivate first."

Twenty years later, she looks at the man in front of her who claims to be the Emperor of Qin. [20 million people can't even get fed, does the cultivation world have such poor places?] Feeling that her goals are ambitious, Weisheng Xue pats his shoulder, "Brother, you need to look further. We are cultivators, let's set a small goal first."

Qin Shi Huang asks, "Like what?" Weisheng Xue replies, "Morning遊北海, evening暮蒼梧." Three days later, Weisheng Xue says, "Brother, this place of yours is too backward, we need to change our small goal." Qin Shi Huang asks, "To what?" Weisheng Xue declares, "Farming, mining, and building flying ships."

Years later, the system finally accumulates enough energy to reconnect to the interstellar network. Weisheng Xue sees the bold, capitalized headline: Archaeological discovery of Mother Planet's ancient era [Qin]... She feels dazed, "Ying Zheng?" The First Emperor, putting down his transmission talisman, looks up, "Teacher."

She stiffly turns her head, "Li Si?" Li Si, just disembarking from a flying ship, bows, "My Lord." Weisheng Xue: ...So I didn't transmigrate to a cultivation world, system, you lied to me!

Note: The female lead and Ying Zheng are not a couple, but there is a one-sided crush from supporting characters towards the female lead. Enter with caution if you mind. The main plot is focused on infrastructure development, with later elements of technology and cultivation. This is a parallel world, a fictional history.
