If the Nascent Transformation Stage was equivalent to the Fourth Ring, then it makes sense for the Deity Stage to be equivalent to the Fifth Ring. This was in line with Chen Heng's understanding of cultivation.
According to what he had learned from those inheritances, when cultivators in this world reached the Fourth Ring Nascent Transformation Stage, they would complete a sublimation.
Their entire bodies would give birth to a brand new Nascent Soul. Even if their bodies died, they could rely on their Nascent Soul to exist alone. They could even seize the bodies of others and revive them once again.
This description also gave Chen Heng an inexplicable sense of familiarity. Looking at it from another angle, wasn't the so-called sublimation and Nascent Soul a process similar to the birth of a true spirit?
