This seed will be the seed of the inner world of the cultivators in the Immortal Realm, also known as the World Seed.
Lu Yi heard from the Yu Family Ancestor about the cultivation in the Immortal Realm, which involves continuously comprehending laws, absorbing Immortal Spirit Qi, and condensing one's own law-based World Seed, eventually creating a Small World based on the laws one has comprehended.
The Small World merges with the Immortal Body, transforming into the Inner World, and then, by inscribing laws within the Inner World, one thoroughly forges it into a unique Immortal Domain.
Upon reaching the Immortal Venerable Realm, the Inner World reaches its zenith, and the comprehension of laws has also achieved Perfection, with the Law Patterns fully inscribed within one's own Inner World, stabilizing the Immortal Domain.
This means that every Immortal Venerable has their own complete world of law.
