Gao Yang and his team's backpacks were mostly 3D bags, except for Glolov and Cui Bo, who carried a sixty-liter backpack each; the rest were a bit small.
After quickly scanning everyone's backpack, Gao Yang's eyes lit up when he spotted Kamp's marching pack. He immediately pointed at Kamp's large backpack and said urgently, "Give me that one!"
Kamp's backpack was nothing more than a pocket with two straps added; it was closed with a drawstring that, when loosened, turned into a large, straight canvas bag with no compartments—and crucially, it was huge. By volume, it was at least eighty liters and could easily hold over a hundred pounds of dirt.
After Glolov took Kamp's backpack and dumped out the contents, Gao Yang quickly placed an armor plate he'd pulled from the front of his bulletproof vest into the bottom of the pack. Cui Bo, who had already prepared himself, started to rapidly fill the bag with dirt.
