The space of the array is like an enormous vertical shaft, bottomless, seemingly leading straight to the Nine Netherworld.
Inside, the yin energy is like a tide, so thick it resembles black ink. It is no longer a vast airflow, but more akin to viscous liquid.
"Black Water Mountain and White Paper City…" Ning Zhuo, upon seeing this scene, suddenly thought of the name spread outside by the White Paper Immortal City.
The shaft walls are smooth as mirrors, neither stone nor jade, seemingly constructed entirely by the array.
Yin energy, like black water, churns within the shaft, roaring, sometimes raising black waves several yards high, crashing against each other with thunderous booms.
Yang Wenning and the others stood at the edge of the shaft walls, all feeling the bone-chilling cold brought by the "black water," colder than ice and snow, penetrating the marrow, even suppressing their own yang energy and freezing the circulation of spiritual power.
