Eight Born Necromancers: Annihilation of Light and Darkness

[Pure Western fantasy undead flow, no elements of immortality/cultivation/immortal cultivation, don't enter if you don't like it] [Light and darkness are one body] [Dark belly] [Strict] [Invincible killing] Dressed as the most humble handyman in the Academy of the Undead, I was stepped on: "A handyman, is he worthy of practicing necromancy?" When I was about to die, the holy light exploded in my body. They don't know that what I awakened is the ultimate taboo of the undead, Light and darkness are one body! Other people's undead souls will collapse when exposed to the holy light. My undead soul swallows the holy light, is covered with gold patterns, and heals automatically. Overwhelm everything! The Church of Light is hypocritical, and its top leaders have long been infiltrated by the void. After seven reincarnations, I was the reincarnation of the God of Annihilation! Bone Guards, Corpse Generals, Soul Spirits, Bone Dragons... The eight natal destinies are all here to kill gods. In this life, I will tear apart the mask of the Holy See and let the so-called light and darkness crawl under my feet!
