Devourer of Ten Thousand Realms [Cultivation Isekai] (Eat Grow Survive)

Power isn't just taken, it's consumed. Look, I wasn't a smart kid. I was an idiot for running away from home.But there was no way I could have predicted that a weirdo was going to fall out of the sky and pass me a key to the entire multiverse like it was a stolen car. Now, I could go anywhere except home, but the multiverse was full of evil cultivators, monsters, and worse. The only way I could survive was by Devouring the power of others, whether I could handle it or not.  Too much, and I'd light myself on fire from the inside.  Not enough, I'd get eaten by a giant bug.  And there were people out there who really wanted to get their hands on this key.  If I wanted to survive, I only had one choice, even if it made me a monster in the process: Eat. Grow. Survive. Content Warning: Violence, body horror, cannibalistic elements, and morally questionable decision-making. Volume 2 - The Immortality Heist - Launching in October
