At the entrance of the mining tunnel.
Sheng Qingyan and Yue Qiyuan, both equipped with breathing apparatus, landed at two separate mining tunnel entrances.
Without wasting time, they dived directly into the tunnels.
The tunnels were deep, narrow, and pitch-black. Wearing goggles, the two went further inside, while Ji You maintained communication with them.
They proceeded carefully yet quickly, traversing a significant distance in an instant. They crossed several doors, mostly wrecked by the black bears, until a minute later when both encountered obstructions—a sturdy alloy door stood in their way.
All around the door, the rocks were scattered with countless massive footprints, clearly from the black bears.
Evidently, it was this door's blockade that saved those inside the tunnel from the bear's attack.
While the bears would resort to breaking the door by force, the humans had more agile solutions.
