It makes sense that su Luxia is questioning the Taoist old man master's method. Honestly it just seems like a way for him to use innocent souls to build his own powers. Since su Luxia is a ghost in this story, I know the ending (whatever it may be, idk spoilers) is probably gonna be her passing to heaven and leaving the girl Taoist master behind. It's gonna be bittersweet but I hope they act cute and have fun at least. Also su Luxia's taste 👌👌👌 bc that girl is cute
