Emperor of the Dark Night, I Just Want to Lie Down During the Day

After traveling through time, he became a wasted prince, ridiculed by the civil and military officials of the court, and the emperor wanted to destroy the entire Xiao family. During the day, I drooled and dozed off. At night, I am the "shadow" that scares the world. My sister was forced to marry? Knock the fifth prince away with one stick. My fiancée is trying to track down my identity? I took off the mask in front of her. The emperor wants to raid his home? I brought 300,000 border troops to the city. Throw the throne to me? No, I want to lie flat. Princess Qingyuan, you choose the emperor, I will bask in the sun. —— [Signed, feel free to read. Pretending to be useless during the day and killing gods at night, system flow + counter-routine, the heroine is not a flower vase.
