The cave abode was extremely spacious and after some quiet meditation, Su Zimo contained his excitement of joining the sect. Placing the sect badge around his waist like Xue Yi, he took out the two manuals.
Spirit Peering Art was a fundamental skill in the cultivation world where almost every cultivator had to learn it. Through lining their eyes with spirit qi, one could determine the cultivation realm of other cultivators.
But of course, there are rare cultivation techniques as well that could help one hide their cultivation realm from Spirit Peering Art's detection.
The Qi Condensation manual could be considered as an entry skill for Ethereal Sect.
Everything from opening storage bags, cultivating the Spirit Peering Art, sword kinesis flight, refining elixirs and weapons required one to have spirit qi.
Because Su Zimo had a Fire spirit root, the spirit qi he could manifest from Qi Condensation would naturally carry the fire element.
