Dan Feng, Earthfire secret chamber.
The air inside the chamber was saturated with a scorching, violent aura that made one's heart race; faint flickers of flame could even be witnessed with the naked eye.
In the center, six cauldrons were arranged in a ring on the ground.
At the heart of the formation, a figure sat cross-legged, face solemn, every muscle taut—astonishingly, he was controlling all six cauldrons, refining pills simultaneously.
It was none other than Xu Yang.
Splitting his focus into six, simultaneously manipulating six cauldrons and refining Spirit Elixirs—this was an extreme trial of an alchemist's Primordial Spirit and skill.
If there was a single advantage, it was that the Earth Vein Immortal Fire beneath the secret chamber made fire control a little easier.
But compared to the difficulty of operating six cauldrons at once, it was nothing substantial.
At a certain moment—
Xu Yang formed hand seals with both hands, his body revolving in place.
