This murky Netherworld Qi is formed by the condensed mixed energies expelled from the Nether River. The first layer, known as "Dust-contaminated air," is harmless to cultivators but can render mortals weak-limbed and unconscious with a single breath.
Mu Hongchen had visited this place no fewer than twenty times, and thus navigated its mountain crevices with ease. Twisting left and right, she swiftly covered dozens of miles, while the three behind her followed closely, not falling behind in the slightest.
After passing another curve, the path ahead suddenly widened, bringing them to the second layer.
This layer's Netherworld Qi is called "Yin Gathering Miasma." Though slightly more potent than the first layer's Qi, the four regarded it indifferently, breezing through in less than an hour.
