The city was far behind them now. Only a deep tunnel was spread before them. Looking back in the direction they had come from, there was just a faint dot of light in the far distance, which only people with super vision could see.
The air was turbid almost to the point of being poisonous. Clearly, Hao Ren had chosen an exit that had never been opened: the air behind the hatch had never been scavenged.
The tunnel was very wide, structurally sound in most parts, and not as narrow or dilapidated as they thought it would be. It was only rather old and dirty, plus there was thick dust everywhere. Traces of years of erosion were apparent. Clearly, compared to the enclosed city, this place lacked the necessary cleanups.
