Reborn as a Turtle: My Evolution System

Crushed by a truck, I awoke in a brutal monster-infested forest... as a palm-sized turtle. Weak, slow, and instantly targeted as prey, my life seemed over the moment a ravenous beast snatched me up to be devoured. But just as despair set in, a 'Devouring Synthesis Evolution System' awakened! Now, every monster I consume fuels my growth, transforming my frail shell into an impenetrable fortress and my sluggish crawl into a terrifying charge. From a helpless meal, I will eat my way to become the ultimate apex predator. But in a world where even humans are 'wild monsters' to be devoured, what terrifying final form will my evolution truly lead to?
