The Necromancer Who Joined the Demon Sect

Li Buyu traveled to the fantasy world and became a little handyman of the Demon Sect. And the gift given to him by the God of Destiny is... A necromancer tome? Without time to think about it, facing the cruel start that could turn into his senior sister's cauldron, his senior brother's spiritual meal, and his master's corpse puppet at any time, Li Buyu made a choice - to turn his senior sister into a banshee, his senior brother into an abomination, and his master into a corpse witch... Many years later, in the face of the crusade and encirclement by the upright cultivators, Li Buyu sacrificed an army of undead, causing many immortals and old monsters to burst into laughter. They smiled and used thousands of methods to attack. "You dare to use this little corpse puppet technique to defend against enemies even if it's not worthy of publicity?!" "Huh?" "Something's wrong!"
