Doomsday King System

This is a novel about a person who died immediately after the apocalypse but returned to the previous moment and obtained the apocalyptic king system! Note: The protagonist in this book acts in a dark way and does whatever it takes to achieve his goals! The protagonist is not the Virgin! No heroine, no brothers, everything is just his tool! Don't be surprised if you see it, and I'd like to ask you gentlemen to bring some flowers. Thank you all This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
