Demon Annihilation! Heroine! the Best Combat Power Ceiling (Certain Bugs Can Be Ignored)

I want to read a book similar to "Demon Slayer: Kimetsu no Yaiba: I Become Muzan's New Father". Please indicate if it is similar to a rice pillar. It can be lifted with one mouth, but not closed.

When Ghosts Are Exterminated, There Are No Miserable Relatives. for Example, the More Pampered Your Brother Is, the Better He Will Not Have His Biological Son.

Demon Slayer Fanfic

I want to read a book like "I Wanted to Be a Pillar, But I Became a Shangxian". I really want to read Demon Slayer fanfics. Does anyone have any? Tell me if you have any, please
