Rare-treasure-type dharma power was special; refining it required at least the Golden Core Realm.
However, according to the Daoist Scriptures, even Dao Seal Golden Core Cultivators could rarely refine rare-treasure dharma power in the Golden Core Realm.
Even if they could refine it, producing a single strand took more than ten years, or even a hundred.
And three or five strands of rare-treasure-type dharma power were not much use to Golden Core Cultivators.
Thus, almost all Dao Seal Golden Core Cultivators still used purple mansion dharma power.
As for ordinary cultivators, most used ordinary dharma power such as [great sun], [Cold moon], and [clear wind] to cast their many spells.
Wang Quan decided to refine [purple qi dharmic power] to replace the pure moon dharma power in his inner landscape.
Although pure moon dharma power was good, after his Foundation Establishment, it had actually become somewhat inadequate.
Many spells could not unleash their original might with pure moon dharma power supporting them.
If he switched to purple qi dharmic power, things would be different.
For others, refining a hundred and eight thousand strands of purple qi dharmic power was as difficult as ascending to heaven.
Yet for Wang Quan, Stone City's ruler whose power and influence reached the heavens, gathering enough purple qi to refine purple qi dharmic power required only a word.
Stone City held hundreds of millions of spirit monsters, nearly a hundred million New-Method Cultivators, and tens of millions of Orthodox Cultivators.
With all these living beings helping him gather purple qi, it would take only a few days.
As for whether gathering purple qi would hold back their own progress?
Wang Quan did not care.
Those spirit monsters and cultivators did not mind either.
No, they were delighted.
Because only in Stone City could they survive.
