Interstellar Journey: Awakening the Earth-Class Repairman System

[Interstellar + System + One Female Lead + Imaginative Planets + Lighthearted + Slow-Burn + Adventure] Chainswords, antimatter cannons, racing through the stars, trains crossing the galaxy, planets of wildly different shapes, civilizations that control the fundamental laws, interstellar archaeology, and eldritch deities of the deep cosmos too horrifying to look at, and much more. Come along on a spectacular journey of cosmic exploration. P.S. The story will have a fairy-tale feel, without too many heartbreaking moments. In a universe this vast, there’s nothing strange about dragons existing. My writing isn’t the best, but I’ll do my best to make the story clear. Please treat it as a bit of entertainment and take it easy while reading.
