Li Rui traveled through time and became Wu Zetian's abandoned grandson, and was thrown into a prison the moment he opened his eyes.
Bored in prison, he drew a map of the world. The jailer exclaimed: "Your Highness, this thing is worth a hundred thousand soldiers!"

Li Rui smiled: "Royal Grandmother, do you want to try to unify the world?"
