Lin Feng’s own mantra, the Heavenly Classic of the Way's Virtues, was not easy to cultivate and its cultivators must be of a certain quality.
Wang Lin, at the start, was the best example. Before his Innate Ability was augmented, even with full values for Intelligence and Determination, it was still extremely difficult for him to cultivate it.
However, if one was able to cultivate it successfully, then the results would be astounding.
Foundation Establishment stage disciples who cultivated it to great effect would surely form a First Class Spiritual Altar, a First Class Spiritual Crucible and when they obtained their aurous core, it would be a purple one.
If the Divine Lands knew about this news, then they would be in an uproar.
However, even though there’s 100% chance of success for forming a First Class Spiritual Altar, it was still not easy to form a Supreme Spiritual Altar.
