The next day.
Inside Danxin Cave, the fragrance of medicinal herbs curled through the air, intertwining with the sulfurous scent of Earth Fire to form a distinctive aroma.
Chen Sheng took a deep breath, drew out the Qingyuan Cauldron, and wrapped it in his Spiritual Sense, enlarging it to half a man's height. Then he began refining a Second-grade High-grade Pill—the Nine Yang Pill.
Spiritual Light flickered at his fingertips as he took out the prepared spiritual ingredients one by one: Nine Yang Grass, Crimson Sun Flower, and more.

Chen Sheng's gaze was sharp as an eagle's, while his Spiritual Sense formed a fine, dense net around the entire alchemy furnace, missing not the slightest change within.

With a soft sound, the flames within the cauldron suddenly fell into disorder.
The medicinal potency, which should have
