The Cauldron has Cauldron Qi, the inherent aura of the Pill Cauldron, which ordinary people cannot perceive. However, as a Pill Sovereign, and a practitioner of the Nine Cauldron Skypassing Spell, Fang Lin could naturally sense the Cauldron Qi contained within the Pill Cauldron.
The primary enhancement method for Fang Lin's Nine Cauldron Skypassing Spell was by consuming high-quality Pill Furnaces. Absorbing Cauldron Qi, although inferior to directly consuming Cauldron Furnaces, could still promote the Nine Cauldron Skypassing Spell.
Besides the Golden Flame Cauldron, Fang Lin had no other Cauldron Furnaces at the moment. Since the Golden Flame Cauldron was to be used for Pill Refining, he could not consume it. Although he couldn't consume the Black Cauldron in front of him, it was naturally possible for him to absorb some Cauldron Qi from it.
