This is the story of a time traveler and a train crew of space heroes, journeying through various worlds on a journey of adventure. The first world is Douluo Continent (completed, Chapter 60). The current world is Yaliluo VI. Pam: "The transition is about to begin, everyone, please be prepared. 5, 4, 3, hey? Why is there someone up ahead?! Brake! Oops, I can't stop!" "The host's life is in imminent danger. An emergency wormhole will be opened, allowing for random travel!" In the starry sky, a train, unable to brake in time, plunges headfirst into a black hole. "Meow!!!" Somewhere in the galaxy, a black cat clutches its head with its paws and lets out a painful scream. Where's the train? Where's my train?
