Taking out the black book, Chu Ning used his Divine Sense to directly start reading the content of the Third Layer of the Refining Spirit Technique.
He then continued to read further down.
Sure enough, the content of the Fourth Layer of the Refining Spirit Technique, which was inaccessible before, could now be viewed.
"The cultivation of this Fourth Layer of the Refining Spirit Technique is much more profound than the first three layers.
If I'm not mistaken, this is probably originally intended for Golden Core Cultivators."
Chu Ning spent a long time before he finished reading through the entire Fourth Layer of the Refining Spirit Technique.
He silently sighed to himself.
If not for the series of treasures he obtained that greatly enhanced his Divine Sense, it would have been difficult to cultivate the Refining Spirit Technique to the Perfection of the Third Layer.
