My Healing Is Too Fast, My Enemies Can't Take It

Good heavens, can someone tell me why the little junior sister from a remote mountain village has an entire spirit-stone vein in her storage ring? Why does she eat with Earth-rank magical weapons, cook with Heaven-rank magical weapons, and sleep with divine artifacts? Why does she snack on thousand-year-old spirit fruit like it's ordinary fruit? Why does she treat ancient divine beasts as food? And why can the father she calls an ordinary man grab heavenly lightning with his bare hands? Most importantly, why does a support spirit master specializing in healing charge straight to the front in team battles???
