According to the lineage records of the Secret Immortal Sect, only when a cultivator breaks through from the Foundation Establishment Stage to the Purple Mansion Stage can they utilize the power of the Ascension Immortal Silkworm to perform the Celestial Reincarnation, undergo Fetal Transformation and Shape-shifting, and thereby live a second life.
Below the Foundation Establishment Stage, both Magical Power and Divine Soul are lacking, making it impossible to withstand the integration of the Ascension Immortal Silkworm, whose powerful Abnormal Power would cause both Divine Soul and physical body to collapse.
Above the Purple Mansion Stage, the cultivator's body structure, Magical Power, and Divine Soul are already formed, making further transformation impossible.
