As the title says, before mhy continues to unfold the game plot of "Honkai: Star Rail", let me first spread the rumor about Doctor Truth's fast-travel story!
There is no cp to travel quickly, there are many private settings, and the OOC characters are absolutely abundant. It is suitable for people who can forgive everything.
Possible worlds include HP, Liaozhai, Avengers, Greek Mythology, Ancient World, etc.
And perhaps as vignettes in chapters 1-2, "The Moon and Sixpence", "Space Exploration Editorial Department", "Rosemary's Baby"...
Intention: Seeking, seeking truth, this is the glory of human reason
