If you like revenge concept with martial arts, magic and system window involved and can't find any manhwa. then don't worry about it cause this manhwa is perfect for it. A quick review on this manhwa by me: MC was betrayed by world and wanted to destroy the world. Then he got selected as vessel of chaos and was capable of destroying world but he doesn't want the hands of others to do it. With this on, he meets his three master who teaches him martial arts, magic and sword technique to make him capable of destroying the world.  Recommended for you to read it to know about MC journeys on his world domination plan.
