After searching briefly, Huo Hai found where the liquid was going. It was slowly spreading downward along the special Spirit Formation around the Demon Pool. One look was enough to tell him that its destination was the Earth Vein.
The Demon Pool itself was an extremely special treasure. The Devil Master had used a Spirit Formation to connect it to the Earth Vein, drawing upon the vast spiritual power of the Earth Vein to continuously transform it into large quantities of Demonic Energy and Demon Seeds. This was the true reason the Devil Master had been able to sweep through the Southern Nations.
Huo Hai gradually discerned some of the secrets behind the luminous liquid from earlier. He had no idea how the Ancestor Tianhui had created this Light Attribute liquid, but it absolutely countered Demonic Energy and could even infect it. Once the liquid containing Radiant Spiritual Power came into contact with the water in the Demon Pool, it consumed vast amounts of energy as it slowly dispersed the Demonic Energy within.
Once the balance of power between the two reached a certain point, it would gradually infect the Demonic Energy and slowly transform it into Light Attribute spiritual power. What an ingenious idea. The liquid in this pool had practically been born solely to deal with the Devil Master.
All the liquid slowly seeped into the Earth Vein along the Spirit Formation. Huo Hai did not need to think to know that it was there to purify Earth's Vein. The true purpose of bringing the liquid here had always been to completely purify Earth's Vein.
"Half the mission is complete. Now we just wait for the Devil Master to return." Huo Hai smiled faintly. If the Devil Master did not die, he could contaminate the Earth Vein again
