Upgrade from skeleton

The pale flame burns the earth, countless dead recover and sweep the earth, the order will be rewritten, and God will no longer be high. "Ding, absorb the soul fire of level-1 skeleton soldiers, and can evolve into level-2 skeleton" "Ding, absorb the soul of level-4 Warcraft frost wolf, and can evolve into undead wolf Knight" "Ding, absorb the soul of ancient dragon, and can evolve into death Dragon Rider". With the evolution system of the dead, see how I ascend the divine realm, kill the God King and rewrite the order.
