The two sides and the ceiling of the underground tunnel were made of stone. In order to eliminate the echoes being produced when people walked inside, a layer of soft carpet was paved on it. Walking on it, Zhang Tie thought about the scenes of Donder walking down this tunnel numerous times—was that guy using this tunnel to gather information? According to Donder, the organization behind his back had already given him a big face by kicking him here to the small Blackhot City. He might have not needed to do anything at all here.
