I once read this QT BL somewhere where the MC was the evil sect leader and ML was a monk. I remember that MC was injured and was being chased by his enemies when ML saved him. The evil sect was actually some good but reclusive people who didn't like to mix with people from mainland. But MC had some kinda treasure map or super powerful martial art book on him so he was plotted against and harmed. I also remember that the first time they had sex in that arc was in a forest or somewhere after killing some people cuz I remember ML thought MC looked sexy with blood on him. Later ML gets banned by his sect cuz he was together with MC but he takes MC as his god/idol so he doesn't care. I probably read it in crysenthimum garden. I think it was FOD but probably not cause I can't find the arc. If anybody knows, please tell me which novel and which arc it's from.
I'm pretty sure it's extra 2 of FOD. If you go to the FOD content page in keztranslations and click extra 2 it should link to the chrysanthemum garden translation
