Circular Radiance Immortal gathers all divine position worlds into one, forming a grand divine world. At that time, behind the True Immortal, a round of radiant light will appear, containing a spiritual world within.
By then, the True Immortal's Dao Heart and Will will undergo a transformation, enabling the temporary integration of the Dao Heart and Will into immortal treasures, amplifying their power several times or even tens of times.
However, becoming a Circular Radiance Immortal is extremely difficult. Not only does it require the divine position world to become stronger and have more divine power, but it also requires the World Immortal to comprehend their own divine power to a certain extent.
Only when comprehension of all divine positions reaches a certain level can the World Immortal merge all divine position worlds to form a grand divine world, gathering into a round of radiant light in the True Immortal's mind.
