Smaller worlds have a volume of only two or three minor nations of the Immortal Realm.
The size of these worlds is primarily determined by whether one's foundation at the time of breaking through to become a Heavenly Immortal was profound?
And how they nurtured and developed their world after the breakthrough?
These are the deciding factors.
When Lu Yuan created this world, he sacrificed the entire peaceful region and specifically amassed a vast amount of Qi Luck. Just in terms of resources, it would not fall below the standard norm, even belonging to the upper-middle tier.
And during the creation of the world, he used two Dao Fruits, making his foundation twice as profound as other Heavenly Immortals.
Hence, after establishing the Taiping World, this world's vastness far surpassed that of the common Cave Worlds.
Ordinarily, a Heavenly Immortal with a weaker foundation might have a world the size of two or three minor nations upon their initial creation.
