After walking for about half an hour in this claustrophobia-inducing tunnel, Noland Lee heard the sound of trickling water.
Reflective water curtains began to appear on the walls on both sides.
Noland took a deep breath and smelled the unique dampness of the underground river.
After passing three more turns, the scene before him became more open and bright.
The width of this underground river was much larger than Noland had imagined.
Like a winding giant snake, it meandered through the underground space filled with poisonous fog.
Dark green spots dotted the surface of the river, giving it a greenish hue.
Upon closer inspection, those shimmering dark green spots were the undead contamination flowing with the river towards the south.
Green glowing bones, flickering green rotting flesh, unidentifiable scales with green glow, and countless severed limbs and dried corpses.
