So I Got Reincarnated as an Ant

"I died a hero... only to wake up as an ant." After sacrificing his life to save a little girl, Ethan Ward expects to be rewarded with heaven—or at the very least, a decent reincarnation. Instead, he hatches from an egg as a tiny carpenter ant in the middle of a monster-infested forest. Before he can even process his new six-legged body, he's chased by a giant hunting spider hundreds of times his size. Just when it seems like the shortest isekai adventure in history is about to end, a mysterious voice echoes in his mind. A System has awakened. Armed with powerful skills like Appraisal, Devour, and Adaptive Evolution, Ethan discovers that every battle makes him stronger, every creature he defeats brings new possibilities, and every evolution pushes him further from being an ordinary ant. There's just one problem... He's at the absolute bottom of the food chain. To survive, Ethan will have to outsmart venomous centipedes, explosive beetles, carnivorous flowers, living fungi, ancient monsters, and creatures that can crush him without even noticing he's there. Along the way, he'll gather an unforgettable band of bizarre allies, uncover the hidden secrets of evolution, and slowly build a colony unlike anything the world has ever seen. But this isn't just the story of one ant becoming stronger. It's the story of a tiny creature who will one day unite monsters, challenge kingdoms, shake the gods themselves, and build an empire that begins with a single worker. After all... Every great empire starts with one tiny step. — Description from novelcodex.org
