As Ling Qingxue's cultivation level was still relatively low and her spiritual power was far inferior to Xia ruofei 's, she did not feel it very clearly.
Even so, she still felt that cultivating in this stone pillar array was much more efficient than usual. She couldn't even sense the effect of the array, but she felt that her mind was more clear than before, and her cultivation was so smooth.
As for Xia ruofei, he had analyzed the formation himself and his cultivation was close to the intermediate stage of the Golden elixir realm. His spiritual power had also improved by leaps and bounds, so he could feel it more clearly.
When he was cultivating, he felt as if there was a warm stream of air that was constantly nourishing his physical and spiritual body. His mind was much clearer than usual, and his cultivation of the 'great Dao Sutra' was also much smoother than usual.
