I'll be straight forward and what I want you guys to tell me are novels which have a similar protagonist , Fang Yuan, to Reverend Insanity. Let story not have harems and an over reliance on people/people relying on the protagonist. I know there're no other specifics but I really want a character as scheming, shameless and intelligent as Fang Yuan for the protagonist as a story I want to read. No romance please. Thank you.
https://www.novelupdates.com/series/soul-of-negary/ - MC of this story does not understand what the heck having a heart means. Carefree Path of Dreams - by the same author as Warlock of the Magus World and MC is named Fang Yuan like one from Reverend Insanity. You could probably guess what kind of novel this is from this much information. Regressor Instruction Manual- About an MC who manipulates his way into other peoples' hearts to get them to take care of him.
