Duskblade

Kaden awakens once again at the dawn of Earth’s cataclysmic “System” invasion, armed with haunting memories of his previous nightmare life. Desperate to overturn his grim fate, he sets his sights on a special druid class—only to unlock a legendary hidden class! 

A druid who had to devour to become stronger! With every enemy he devours, the madness increases. The nature twists and contorts in his presence. Plague spreads where he goes. The cursed forests become his grove. 

Would the fallen druid be able to face the twisted alchemist who once enslaved the entire planet? Can Kaden master this cursed power to save humanity—or will it consume him, turning him into the very evil he seeks to destroy?

It had to be something rare-grade at the least!

Kaden's thoughts churned in a frantic spiral, struggling to wrap around the sheer absurdity of what had happened. This wasn't how evolution was supposed to work.

His fingers dug into the bark of the tree, grounding himself as his mind replayed the sequence of events. He had accepted his F Rank evolution, expecting the usual requirements—perhaps a trial, a skill refinement, a temporary boost. Instead, he had been swallowed into that cocoon.

If he had hijacked that creature's evolution, then what exactly had he evolved into? Did he absorb some of the genes of the beast? Was he going to take on some of the beast's characteristics? Was that going to make him more powerful or less?
