The laws of birth, aging, illness, and death weren't only about humans, the world, and the myriad spirits, but also about different worlds.
There were tens of thousands of worlds in the Sea of Realms, and they could be counted as the Great Realm, the worlds, and the realms.
It was based on the number of Immortal Ascension stage cultivators the world could accommodate.
Due to the existence of the Immortal Ascension stage cultivator, some worlds that should have been heading toward "death" were still struggling in the Sea of Realms.
During the process of an Immortal Ascension stage cultivator's cultivation validation, the world could also completely inscribe the cultivation technique of the Immortal Ascension stage cultivator. Even if the Immortal Ascension stage cultivator pushed open the door and left, or if something unexpected happened and he was unable to return, the world where he achieved his cultivation validation would still have his cultivation technique.
