Dominating The Age Of Gods With My Monthly Sign-In System!

In the primeval world of Ur, the thirteen Major Gods dictate fate.When Caius transmigrated into the third son of House Draxos, he realized two terrifying truths.First, he was the destined Main Villain of a dark fantasy epic, fated to be executed by the righteous Protagonist.Second, after being rejected by his family patron, the God of War, the original Caius formed a pathetic contract with a dying Minor God of Ash just to attend the Divine Academy.To the world, he was a laughingstock but Caius quickly knew that the Protagonist destined to kill him is no hero.He is the psychopathic reincarnation of the God of Light. His grand quest to gather the most powerful maidens is actually a massive slaughterhouse.He intends to groom them, harvest their divine contracts, and sacrifice them to devour the authorities of the thirteen Gods for ultimate supremacy.To survive his execution and shatter the reincarnated God and his perfect game, Caius relies on the cheat that finally finishes loading in his mind.[Ding! You have awakened the Monthly Sign In System.]It was a system that was activated only once every thirty days but when it does, reality breaks.For his first monthly rewards, the System gives him an overpowered grimoire and forcibly binds his soul to the ultimate anomaly: Ereba, the Chained Goddess of the Void.Instantly, the Void devours his pathetic Ash contract replacing it with a lethal Void Mana capable of canceling and consuming the thirteen Gods and their magic.Now operating from the shadows, Caius steals the doomed heroines before they can be harvested.As the global fate rewrites, the reincarnated God watched his flawless harvest violently unravel.Wait, how is a failed noble devouring the Gods?!
