“God of blackfield” “Real man” “Again my life” “Medical return” are manhwas similar to this, and for reincarnation into modern world I haven’t read a lot but I would recommend “holy idol”.
Oh god holy idol is hilarious! There's not a chapter that i didn't laugh!
https://www.mangago.zone/read-manga/villain_initialization/ this one too but ist fantasy based world
Can anyone recommend me manhwas similar to this and reincarnation into modern world?
