silver eyes, white hair, and flawless skin. the MC is Albino then?
what immortal? what billion years old? true cystal is life..
food is life
it's up to readers(i think?) to judge the MC's personality, either way it's still up to his development(and author)
well, instead of being a cultivator, why not being a warrior/soldier? but, maybe there's something in this mortal..
