His exceptional abilities led him to become the warden of the Interstellar Peace Corporation.
That day, his lovely secretary quietly told him that there was a special criminal he needed to interrogate.
then.......
After he entered the interrogation room.
Kafka, who had deliberately been arrested, looked at Gu Yan with a playful smile: "Oh? The warden of the Interstellar Peace Corporation is so young."
Looking at the person in front of him who was completely unaware of the danger approaching, Gu Yan revealed a kind smile.
Ah, things are getting interesting.
.......
.......
Then, the story begins.
Gu Yan discovered that there were far too many criminals in the world that needed to be eradicated.
The style of Xingqiong Railway also changed dramatically.
“Ms. Bronya, you wouldn’t want me, the warden, to put your mother in jail, would you?”
"Pioneers, your journey ends here. You have committed the crime of vandalism!"
"Miss Pera, we have received a report that you have committed smuggling by purchasing too many books!"
Looking at the group of people being thrown into prison, Gu Yan revealed a satisfied smile.
Today is another peaceful day.
