Reincarnated as a Dragon Hatchling(2017)

Tensei Shitara Dragon no Tamago Datta: Saikyou Igai Mezasa Nee

In a world full of dangerous monsters, our unnamed protagonist finds himself reborn at the very bottom of the food chain as an immobile, powerless egg. Even just hatching will require leveling up by fighting monsters–the same monsters who’d love to eat him as a snack. But with the help of the mysterious voice in his head, he’s determined to grow into the most powerful creature in the world!
