The teacher who had been crippled by Mika lived in the Central District of Chenxi Port, on the sixth floor of a building.
It was nightfall.
The area turned into a bustling market, with Mika wearing a coat, concealing a loaded firearm inside.
Nobody would suspect that someone who appeared to be of student age was carrying a Level 1 prohibited item.
The portable firearms, regulated at a higher grade than long matchlock guns.
It's like how on Earth craft blades are freely available; if you carry one around, it doesn't pose much of a threat, and onlookers will just have a laugh.
But a spring-loaded knife or dagger that fits in your pocket is a different story; no one can detect it, and who knows if you're some anti-social personality ready to quietly skin a few people.
