“I am the rot in your foundation. I will crawl back from hell and bury this world.”Those were Red’s final words as his classmates—the people he once sought validation from—watched him dissolve. They stole his life force to fuel their own ascensions, becoming Paladins, Sages, and Kings. They threw his empty husk into the Abyss, satisfied the 'Terrorist's Son' was finally gone.But death was not the end. While his body lay broken in the abyss, his soul drifted to the sanctuary of a Forgotten God.Awakening the forbidden SSS-Rank Talent [Exponential Divinity - 100x Growth], Red realizes that in this world, power isn't given—it's built. He doesn't need heroes; he needs monsters.From the chitin of hyper-evolved insects to dragons, from eldritch horrors to the nightmares sleeping in the dark, he begins to construct a civilization that defies the natural order. Under his hand, the weak do not just survive—they evolve into calamities.The Heroes are leveling up in their golden towers. The Gods are watching from their thrones.But in the shadows, Red’s Strongest Civilization is already preparing for war.[Betrayed and sacrificed, I awakened an SSS-Rank Talent. While others struggle to build a village, my civilization grows 100x faster.]
