Emperor of Nothingness

Legend says that when a person dies, they become a ghost and go to the underworld. But what happens when a ghost dies? Mortals can cultivate to ascend to immortality; what can ghosts become through cultivation? Immortals cultivate pure yang spiritual energy to create a pure yang primordial spirit; ghosts feed on yin energy, transforming yin into pure yin spirit; corpses take the path of extinguishing the soul and eternal life, refining the physical body! I cultivate immortals, ghosts, and corpses simultaneously, dominating the three realms and opening the underworld! The mortal world and the celestial realm honor me as the Emperor of Nothingness, and the underworld calls me the Emperor of the Underworld!!
