@davinademilo: Grandmaster of Demonic Cultivation, Scum Villain's Self-Saving System and Heaven Official's Blessing are all works from Moxiang Tongxiu, but the settings are distinct from each other.
Fanworks often remix the details, but while they're all
Xianxia setting adjacent, they have fairly different magic mechanics and expectations, and they're character-centered stories rather than "typical" self-indulgent xianxia/transmigration webnovel/manhua. Scum Villain came first, Grandmaster second and Heaven Official's Blessing third, and it shows, reading the original stories.
Scum Villain further separates itself from the other two by being an affectionate parody and genre critique rather than fully fledged fantasy drama/romance. Grandmaster and Blessing have some common elements of mystery and investigation in their plots, but more important concepts in both stories are things like social prejudice, empathy, and the ability of love to save people.
