Heya! So there was this completed korean (I believe) novel that used to be on WuxiaWorld (not anymore cuz of licenses) about an assassin who didn't have a heart and got sent to another world. I can't remember or figure out what novel it was though, for the life of me. If someone could help then please, I'm begging you ;-;
This somewhat sounds like King of the Battlefield But I'm not sure as it wasnt on WW. Still, I can't think of any KR series that have been on WW before that fit that description
Ah I found it using Wayback Machine guys thanks for the help! It was called I'm Sorry For Being Born ;p
