Night Swamp, also known as Ruoshui River. Within the Ruoshui, nothing grows and birds struggle to cross.
Now Ning Xiaoxian is standing by the bank of the Ruoshui, feeling that this river indeed looks ominous. In this world, where the soil and water are unpolluted, she has seen rivers and lakes with extremely clear water, yet only this Night Swamp has dark grey water! The moment she saw the river, she thought she had returned to Huaxia, to the mountain behind her childhood home where a small river was polluted by a paper mill.
She scooped up a handful of the river water, frothing and both slippery and greasy to the touch, with a faintly fishy smell. It indeed resembled heavily polluted water.
Looking across, the river channel, three hundred li wide, where the dark grey water was flowing slowly, it's no wonder it was named "Night Swamp".
