Stardome Railway: Little Ghost on the Train

Feibai, the veteran otaku girl from the second generation, luckily traveled through time, and we deeply regret this. I originally thought I could kill people in the world after time travel and be the savior in a novel. Turned into a little ghost with no fighting ability? I also encountered an unreliable system. Fortunately, the timeline was advanced early, and the Star Dome Train was added as the second "mascot" on the train. [The host only needs to consider whether the system is broken, but I, the system, have much more to consider] Feibai: So this is the reason why you messed up? ————————————————————— Regarding this, one of the worst unknown guests said: "Aha has never seen such a stupid junior, and Aha is definitely not Aha!" A piece of scrap metal said: I can't understand! Mistake! Mistake! A certain idiot said: Build a wall! Build a wall! ("Company": King Amber means that Ms. Scarlet White should join the Interstellar Peace Company and become a cornerstone of the great way of preservation!) Real-name online pharmacist: Poor child, abundance will grant you relief. Peeping Tom said: Only spiritual consciousness exists but there is no image of the body. No memory exists but there is recording. The ability cannot be seen with the eyes but within the reach of the hands. In this regard, the old prophet Mo Wang said:? Time for guest assassination? Meeting a ghost really looks like me ————————————————————— When a life form with only consciousness and no container appears in the world of Starry Railway, what kind of sparks will it create when it collides with everyone?
