Powerful mage MC finds themselves in a younger body in the future of the world and has to deal with the extermination of an intelligent enemy that has arisen in the time they were absent. In the mean time they pick up disciples and teach them how to fight while also encountering enemies that are nearly capable of besting their seemingly all-powerful magic. Good reads if you want to see the subjugation of a cocky enemy force. Main difference is that Disqualified Crest more of a travelling adventure feel and I Became A Legend has Cthulu/alien imagery.
