Reborn Crow: Comes with Unlimited Lifespan

"I'm super, why did I turn into a bird?" "The system doesn't have it either. Let's play... Wait, I have unlimited lifespan?" Bring me the Krypton Life Upgrading Technique! A forbidden technique that burns life-span and explodes seeds? Give me more strength! The villain is too strong and even Krypton Life can't defeat him. I just lie down on the spot and wait for the opponent to die of old age! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
