The Hidden Stars

"Plug-ins" are necessary props for time travellers, which often make them the protagonists of the era. But if there is far more than one time traveler in this world, then who should be the protagonist of the era? They come from different worlds, have different memories, and carry their own "plug-ins" - unique golden fingers. Maybe it's the eyes that can see through the value of all things, maybe it's the hands that create things out of thin air, maybe it's the wisdom that is far ahead of the times... These talents allow their life trajectories in other worlds to quietly deviate. But to this world, they are all foreign objects, and they will be eradicated once discovered! "If it's just like this, there's nothing to worry about. I'm more concerned about the cause than the result."
