He should have stopped leveling at Level 100 and gone to an area with the weakest Level 601 monster and one hit killed it using all his mana to unlock all his Stat boosts for his Title.
Ngl I'm going to need more I usually like super evil main characters like lelouch leylin fang yaun but this skill and plot is so good that I want more .
could you summerize the changes that you make in past chapters in the authors note, so that I know what changed since I don't want to reread the whole chapter to find out that only spelling or grammar was fixed. thanks
