'Start again. Gather qi in your Dantian. Retake the medicine like you did last time.' Bai Zhe told them to hurry to perform the next step immediately.
When the qi in their Dantian was at a level that pleased Bai Zhe, he told them to release the qi they had gathered again. This time, their veins were torn apart and recreated in just a split second. Though the pain was lighter, the two were very uncomfortable, as if their hearts had stopped for a while and beat again.
'Don't lose your focus on the qi. Pay full attention to only qi control,' warned Bai Zhe, so they focused on qi control again.
The process was repeated over and over: destroying then recreating organs, destroying then recreating muscles and nerves. destroying and recreating new skin. In the end, qi pulses were also destroyed and recreated. It was the third day already when they finished every step of the process.
