After an unknown amount of time, the Soul Power vortex stopped greedily devouring the pure energy. It simply rotated steadily in the air, slowly absorbing the energy drifting around it to nourish its growth.
But it was still one final step away from becoming a fully formed Soul Core.
It had to collapse.
A true Soul Core contained a measure of spatial power, and that trace of spatial power was what allowed the Limit Douluos of later generations to traverse space over short distances.
Of course, for a Soul Master to traverse space, they needed the support of at least two Soul Cores, as well as reserves of Soul Power on par with a Limit Douluo.
Whether the Soul Power vortex could successfully collapse rather than immediately explode out of control was the key to forming a Soul Core capable of helping a Soul Master cultivate automatically.
From the moment he began condensing his Soul Core, Lu Qiufeng had kept his eyes closed, using his Mental Power to perceive and control everything throughout the process. This was also Tang Liu's requirement, because the Soul Core Lu Qiufeng was condensing would be absorbed into his Upper Dantian. Doing this would give the Soul Core a stronger Mental Attribute and also help him wake smoothly from his state of feigned death afterward.
Although this Soul Core was condensed from Soul Power, once Lu Qiufeng successfully absorbed it into his Upper Dantian, his continued cultivation would gradually replace the Soul Power at its center with Mental Power. Eventually, instead of the Soul Core driving his Soul Power and Mental Power to circulate together in a mixture, his Mental Power would remain within while his Soul Power circled around the Soul Core outside, fully transforming it into a Mental Attribute Soul Core.
