Unkillable Gaslander

Y/N was your average lad living on a farm with his brother when a terrible fate befell him.
But fear not for he has a second chance at life thanks to reincarnation but ends up in some place even worst.

The Gas lands, a world where the planet is split up into 7 layers each with a continents that revolve around the core of the world and on all of them live terrifying monsters that hunt humanoid life.

But there is another catch for our dear Y/N, he has gained a form of immortality that will keep him alive from even the most terrible of wounds, downside it will keep him alive through the most terrible of wounds.
