The mine of Hiddell Mining Company.
Lu Zhou followed Ling along the abandoned rails, down the path that was in his memory, and towards the depths of the mine.
Because of its abandonment, this mine looked quite dilapidated, as if it could collapse at any time.
Lu Zhou's gaze wandered inside the mine. When they were halfway through their expedition, he suddenly stopped and knelt down. He reached out his index finger and wiped it on the ground.
He looked at the dust on his carbon-fiber gloves.
Lu Zhou whispered to himself as he rubbed his fingers together, "Someone was here."
This cave was a dead end, and the wind and sand from outside couldn't blow into here, but the footprints on the ground were all erased.
Obviously, after he left, someone came here and investigated the situation.
