Have you ever recommended a novel from another world where the main character likes to sleep? He loves to sleep whether he's in class or as a mercenary?

I recommend the Invincible Sleeping God System. The main character especially likes to sleep. Whether it's cultivation or dealing with various challenges, he relies on sleeping to obtain strength. This is definitely a relaxing and interesting novel from another world. I suggest you read it. I hope you like this fairy's recommendation. Muah ~😗
