The rules of this world were very few but game-like.
According to the information Alex received, this world is filled with all kinds of beasts and bizarre monsters. Killing these monsters would drop various ranks of crystals, and these crystals could be used to draw out rewards from various roulette wheels.
Talking about roulette wheels or even treasures and strength, they are divided into five ranks in this Domain World. These ranks are Common, Rare, Legendary, and Mythical.
Treasures below the False Rank were all considered Common Treasures within this Domain World. Likewise, cultivators below the Life Creation Stage were regarded as Common Cultivators.
The Rare Rank included False and True Treasures, as well as cultivators at the Life Creation Stage and the Death Domination Stage.
