A mechanical and cold voice echoed inside the train compartment: "If the Insect Race Civilization were to attack, it would cause a great commotion; it's impossible to be this silent."

"Did it just disappear like that?"
"Yes."
"What's the reason?"
"It's currently unknown."

The young man, with a somewhat unpredictable expression, sat back down. The situation seemed more urgent than he had imagined; a planet just 0.4 light-years away from him had suddenly vanished without a trace.
This is incredibly baffling, isn't it?
It couldn't have just collapsed into a black hole, right? That should be impossible, after all, it was a habitable planet. Moreover, if it had really collapsed into a black hole, his Purple Cloud Star would not be so lucky now either.
Then how was it destroyed?
In this universe, the unknown dangers seem to be greater than he had imagined.
