Although this isn’t exactly wuxia, I would take Qianye from Monarch of Evernight and transplant his abilities and skills into a wuxia setting. He would be a blood cultivator as well as a dual body cultivator as well. And what ties the two cultivation arts together seamlessly instead of clashing is the common but unique cultivation art that increases levels and power at the expense of the self, a heretical art, but cleanses the body and strengthens it as well. This cultivation art also leaves a slight residue of the light element and amassed enough in the body becomes the more purer yang energy, which is the glue tying the two cultivation arts together.
This character in a wuxia world would look like a dual yin yang cultivator who is also a body refiner.
