Bai Rouyun took a deep breath and calmed herself. She knew that she had to empty her mind when she began refining medicine completely; she had to put her entire focus on the ingredients and the purification of the energy within.
Xiao Jin had turned into a cauldron, but Bai Rouyun could sense her support. As she ignited the spiritual flame, she began refining the ingredients one after another, keeping each pool of herbal liquid in each corner of the cauldron, separated from one another, while she was refining and purifying the next.
Eventually, after they all had finished this procedure, she began slowly urging the pools of liquid to merge together.
This was the most challenging part of refining pills. Having to merge the purified energy was difficult as each medicine had a different amount of energy, and different nature, so they could repel each other, or they could try to merge faster.
