The Slacker Demon Lord Is Forced to Subjugate His Own Slacker Life

(A satisfying, drama-free story, so sit back and enjoy. The protagonist has style, and the heroines aren't self-sacrificing doormats.) After sleeping for 600 years, he wakes up and, in an effort to clear his subordinates' names, somehow ends up teaching them how to fight him. He's the Demon King, yet he has to defeat himself? He's the Demon King, yet a group of enemies who keep shouting that they'll destroy him swear their lives to him, and even the girls throw themselves at him? Demon King Lin is still looking forward to a future of lazing around.
