Manhwa Recap: After successfully leaving Earth, humanity has spread to several star systems and developed into a new species of humans that are taller and have extraordinarily long lifespans. Meanwhile, extreme pollution and overdevelopment have turned Earth, the once-thriving mother planet, into a nuclear wasteland. With an average lifespan of only 40 years, the surviving original inhabitants of Earth are now widely discriminated against by the new humans. Among these natives of Earth is the protagonist, but in contrast to others who have given up, he puts in a lot of effort to become an even better mechanic than the new humans. #manhwa #manga #manhua
