In the past two months, although Xia ruofei did not deliberately cultivate in the spirit map space, his cultivation had improved to a certain extent due to the unique environment and the fact that he needed to cultivate to recover from his condition sometimes.
Now, Xia ruofei could clearly feel that he was about to break through the bottleneck of refined Qi level 9.
His experience told him that this was actually a sign of a breakthrough.
As for how long it would take, it was not easy to judge. It was possible that he would break through naturally in the next cultivation, but it was also possible that he would need to drag on for a period of time.
However, he was sure that he was not far from breaking through to refined Qi level 9.
Liu chengfeng felt that his knowledge system of cultivation that he had formed over the past few decades was about to collapse.
