After Ye Han discovered the space over a hundred feet across inside the Purple Cauldron, he found that its blue-cyan soil actually produced wisps of heaven and earth spiritual energy. The Purple Cauldron could absorb that energy directly and convert it into its own aura.
This aura was exactly the same as what the Purple Cauldron absorbed when Ye Han took Qi Refining Pills, Spiritual Qi Pills, and the like to restore his cultivation and spell power.
However, the space generated heaven and earth spiritual energy extremely slowly. An entire day's output might not even equal a tenth of the most ordinary Low-Grade Qi Refining Pill, making its recovery rate exceedingly slow.
But he could not compare them like that. This space had only just been born. If he could find a way to increase the rate at which it generated heaven and earth spiritual energy, or even enter it himself, then he would truly possess a spatial treasure of his own.
For now, Ye Han had yet to find a way into this space within the Purple Cauldron. Of course, this was no time to investigate it either.
The Purple Cauldron gaining this space was purely an unexpected windfall. Its potential for growth might be considerable.
What puzzled Ye Han was that when he first came to the Ice Refining Prince's house, the Purple Cauldron had shown no reaction to the room containing the Treasure-Refining Puppet.
Yet this time, when he saw the little metal sphere from the doorway, it had not reacted either. Only after he entered the room had the Purple Cauldron responded.

Perhaps, to the
