The Qi-refining Realm is divided into three phases and nine levels, with the early phase consisting of levels one to three, and anything above level three is considered the middle phase of Qi Refinement.
Mo Hua's cultivation had already reached the peak of the third layer of Qi Refinement, just a step away from breaking through to the middle phase.
After practicing Tianyan Jue for no more than half a month, Mo Hua felt that his Qi Sea was brimming, unable to refine any more spiritual power.
This also meant that Mo Hua was about to make a breakthrough.
Normally, to break through using other cultivation techniques, one would need to prepare special Heaven and Earth spiritual items to stimulate the meridians and Qi Sea during the breakthrough in hopes of overcoming the bottleneck and advancing to a higher realm.
Tianyan Jue doesn't require any special spiritual objects to assist in cultivation, so one should be able to continue cultivating.
