The silver flame steadily flowed out of the ground. It released a gentle glow, possessing a spiritual energy aura as the pure light continuously entered the medicinal cauldron.
The entire stone room was circulating with pure white light, curling around everything like a faint mist. The mistiness and dense Spiritual Qi made it seem just like a proper immortal cave.
This kind of fire fiend was definitely extraordinary. Other than possessing the most suitable temperature, the most important thing was that it could offer a special spiritual energy that could enter the medicinal herbs and condense Life Qi, helping form a spiritual pill.
The silver flame pulsed and the bronze medicinal cauldron became enveloped by a milky white Spiritual Qi, the many markings upon it all coming to life.
Elder Han closed his eyes and sat in the lotus position as he guarded the medicinal cauldron. His withered body didn't have any signs of life.
