Qin Fengming naturally already knew that any Spirit Severing cultivator possessed methods of driving the immense soul power within their body. Such control should be no weaker than his current use of the Treasure Refining Ghost Art secret art.
Before cultivating the Treasure Refining Ghost Art, he had believed that there were very few secret arts in the Cultivation World specifically devoted to refining soul abilities. Now that he knew the secrets of the Divine Connection stage, his view had naturally changed.
However, Qin Fengming still knew that those incantations specifically used to refine soul treasures were truly far inferior to the Treasure Refining Ghost Art. They merely connected with the sea of consciousness and used immense soul power to refine soul treasures. Even if they could drive soul power to launch attacks, they were still worlds apart from the Treasure Refining Ghost Art.
That was because the Treasure Refining Ghost Art was very likely an art specifically used in the Immortal Realm to cultivate the soul. It could allow the soul to grow independently, apart from the cultivator's own Core Nascent realm.
Of course, the Core Nascent had to be able to withstand the support of that immense soul power as well.
But no matter what, this unorthodox method of cultivating the soul found in the Treasure Refining Ghost Art was far beyond anything that could exist in the Spirit Realm. Nor could most Spirit Realm cultivators know of it.
Back then, in the Yunmeng Mountain Range, the Mahayana divine sense had said that the Treasure Refining Ghost Art was an art specifically used to cultivate the soul in the Miro Realm, and had warned him not to use it casually. Ever since then, he had guarded this soul art with extreme care, rarely using it unless absolutely necessary.
