Everyone Is Demonized: I Started as the Immortal King

[Summoning + Farming + Army + Immortality] The blood moon descends and the world changes. Seven billion people around the world have become demonizers. Fang Gan was reborn before the blood moon came, and successfully fused himself with the Lord of Bones and became the King of Immortality! Summon an army of skeletons, overthrow all monsters in the world, and build a necropolis, a place of pilgrimage for countless undead! Someone turned into a bloodthirsty demonic tree and evolved by sucking the blood of demonizers. However, he was defeated by countless skeleton warriors and became the nourishment of the immortal king. Someone turned into a ferocious giant beast, which could easily destroy a town with its powerful body strength, but was stabbed to death by a powerful skeleton cavalry. Some people have become ghosts wandering in the city, nourishing themselves by absorbing the fear power of others, and can only become nutrients for the skeleton mage. Until the day when the blood moon fell to the earth, the stars shattered, and billions of evil gods tore through the sky to launch a massive attack, the evil gods discovered that what was waiting for them was a huge undead army that was invincible in the world...
