As Giant City entered first-level war readiness, the atmosphere within the city became grave.
All active City Defense Army members assembled, retired soldiers were recalled for duty, and a large number of Scavengers were drafted into the militia.
The seldom-seen Border Iron Guards, now fully in formation, appeared atop the high walls of the Giant City.
Within the Lava Mine City, all major factories were directly converted into military producers, fully engaged in ammunition production and continuously sending supplies to No.3 Border City.
Officially, various preparations were also made for the potential arrival of the Disaster Fog.
Among them, dangerous Taboo Items were even brought out.
The one most likely to stop the Disaster Fog was the Class B Forbidden Item Mixed Element Banner.
Composed of three independent Banners, it had the ability to divide space. Should the Disaster Fog be trapped within it, it might be possible to prevent its spread.
