The main formation of the Circumference Heavenly Cycle Purification Grand Array operated steadily above the abyssal vortex. Light of Chaos cascaded down like a waterfall, stripping away and purifying the Turbid Fiend Qi and tainted blood layer by layer.
Pure, pale-golden fiend qi flowed continuously through twelve spatial passages into the tribes' secret realms on Mount Buzhou, while golden-red blood essence poured through the central passage into the Pangu Blood Pool.
The entire array was like a beating heart, transforming the Blood Sea's filth into nourishment for the Witch Clan, day and night without rest.
Yet the Blood Sea was simply too vast.
Although the abyssal vortex was the source of the Turbid Fiend Qi, where it was densest and most concentrated, the boundless Blood Sea had accumulated Turbid Fiend Qi over countless ages, and it had long since seeped into every corner.
The main formation could only cover the core region around the abyss, leaving the Turbid Fiend Qi Nodes scattered throughout the Blood Sea.
Leaving them unattended would not affect the main formation's operation, but it would waste a great deal of usable resources.
After discussing it, Pan Xuan and Houtu decided to establish Secondary Purification Array Cores throughout the Blood Sea and link them to the Abyss Main Array.
With the main formation as the hub and the secondary array eyes as feelers, they would extend the purification network to every Turbid Fiend Qi Node in the Blood Sea, maximizing its efficiency.
This work could not be rushed.
The Turbid Fiend Qi Nodes were spread far and wide throughout the Blood Sea. Some lay in its shallows, others beneath abysses a hundred thousand feet deep.
Some were hidden in the lairs of Blood Fiends, while others were buried beneath layers of filth deposited over countless ages.
