Deadworld Isekai

Matt's in the prime of his life. So when his doctor tells him he only has months to live, he figures it's just really bad luck. But it's about to get a whole lot worse. When Matt's Earthly form finally expires, a truck-avatar system gives him the opportunity to become a hero on the paradise world of Gaia, a supposedly verdant, rich land teeming with plants and potential. What he finds instead is a place completely bereft of life. A literal dead planet. Thanks a lot, truck.

When Matt Perison first came to Gaia, everything was wrong and dangerous. He was promised redemption and repayment for dying of cancer, but that turned out to be a lie. He was promised a nice place in which to exist, but instead he got death. He was promised, in all ways, good. But what he has, in all ways, is bad. He's made the best of it though. Aided by his system guardian, Lucy, and the dungeon system itself, Barry, Matt began to build a life for himself. He's getting pretty good at surviving in a place where nothing else is alive. But surviving isn't all there is.
