Ji You and Chu Jiaojiao were wearing protective clothing, helmets, and goggles, almost no skin exposed. Fortunately, all the protective equipment was soft, form-fitting, and lightweight, not affecting their agility at all. Once fully equipped, the two slowly descended from the edge of the collapse into the underground. Inside, it was pitch black, without a hint of light.
Worried about alerting the Black Gold Rats, they dared not turn on their flashlights, relying instead on detection equipment and the guidance of Shen Changqing and Sheng Qingyan from the command center to move cautiously forward.
The entire underworld seemed like a maze formed by countless tunnels, innumerable and invisible. The deeper they went, the more lost they felt, but Ji You and the others recorded their progress every 10 meters, further aided by Dock's monitoring equipment, ensuring they didn't worry about getting lost.
