Yuki crouched in the corner of an unnamed alley, peering through the gaps in the low houses at the distant platform.
This thing was hastily constructed in a short time. The government had brought in a large quantity of explosion-proof stone cage nets—a kind of collapsible three-dimensional grid made from alloy filaments and semi-closed bags made from polymer materials. Once stretched out at the needed place and filled with sand or stones, it could form a solid wall.
It looked like a building made of blocks of dirt.
The explosion-proof walls and stone cage nets could even be stacked on top of one another to form taller structures. The rapid advancements in modern materials science had made this thing more convenient. It was capable of effectively resisting bullets and even explosions.
