My First Isekai Hit a Hydrogen Bomb—What Could Go Wrong?

Lu Yi's first interdimensional journey lands him at ground zero of a hydrogen bomb test on Bikini Atoll. With no control over his destination and only luck (or authorial whimsy) to guide him, this hapless transmigrator must survive apocalyptic scenarios armed with nothing but wit, a memorial for his deceased hamster, and an alarming willingness to abandon his humanity. Each door opens to a new world where opportunity and catastrophe arrive hand-in-hand. Will he master the art of dimensional travel, or become another casualty of cosmic bad timing?
