Qin's Wind, Chu's Moon

I transmigrated into the body of a princess from Chu in the era of Ying Zheng, and I stay alive by revealing history.

I tell him he'll conquer Han in three years, so he insists on doing it in one day.

I tell him seeking immortality will kill him, so he turns around and captures aliens to make pills.

When I'm forced back to the laboratory, he tears open a rift in spacetime with his bare hands:

“Come back with me.”

Behind him, countless cosmic warships kneel as one:

“Welcome back, Empress!”
