Global Evolution: I Devour Everything.

The night the gods descended, the world ended in screams. Gigantic eyes split open across the sky while every human on Earth heard the same message: “EARTH HAS BEEN SELECTED.” Then the monsters came. Cities collapsed overnight. Oceans mutated. Entire countries vanished beneath waves of flesh and fire. Humanity awakened supernatural abilities to survive, but survival only created something worse. Evolution. Tobi Vale awakens a strange ability called the Adaptive Devour Evolution System, a power that allows him to evolve by consuming monsters, absorbing traits, and surviving deadly situations. Poison sharpens his body. Pain strengthens him. Devouring powerful creatures changes him into something increasingly inhuman. At first, Tobi only wants to protect the people close to him. Then he learns the horrifying truth behind the apocalypse. The gods never came to save humanity. Earth is a feeding ground. Now, hunted by monsters, cults, evolved humans, and the gods themselves, Tobi must evolve fast enough to survive a world where power is everything. — Description from novelcodex.org
