Eunuch Wu Emperor

I was in another world, or in the palace. I thought it was another novel about a reborn emperor, but it turned out to be in a cleansing room. There is a person sharpening a knife in front of him, but this is the simplest dilemma he has ever faced. Let's see how the protagonist turns things around and reaches the pinnacle of martial arts. The world is more vast than we imagine. Open this book. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
