"System, give me a chance. I really don't want to be a monster." "The world is about to usher in a new era, please host to increase your demon power as soon as possible." "Ding, the host's current title is: "The Little Demon Who Just Arrives". Please increase the demon power as soon as possible." On a cliff, a young man with a handsome face is hanging on the edge of the cliff, with a look of helplessness on his face. Although he has been in this world of demons and monsters for more than 20 years, and his spiritual power is clearly comparable to that of the Demon King, why does the system still let him become a monster? Come on, being a monster is really worthless.
