Isekai/Reincarnation/Medieval(Dungeons and Quests) (Male Lead OP)

This dude dies in a tomb but then a relic saves him. He goes back 15 yrs in the past and gets revenge while also becoming really op.

So mc dies from over working himself, with his life being going to work and coming home to play paradiso. He gets reincarnated as a fat worthless Lord in Paradiso who isn’t even a side character. With his knowledge of the game he exceeds everyone’s expectations and works to become the main character of the game bc he’s petty like tht.
