The herbs in the circular vessel were being slowly permeated by spring water containing powder and medicinal power. Zuo Feng felt this change and showed a slight hint of joy on his face, as the Spiritual Energy became more stable. It was as if keeping the circular vessel at this constant temperature was just right.
On the other side, steam was continuously evaporating from the cylindrical vessel, delivered through a metal tube. During this process, a small portion of liquid was completely evaporated out of the vessel. This evaporation did not make Zuo Feng regretful; rather, it left him somewhat excited.
Because the evaporated spring water contained impurities, while the pure spring water carrying medicinal power flowed through the conduit into the circular vessel. It wasn't long before all the spring water in the cylindrical vessel disappeared, replaced by a small amount of liquid being injected into the circular vessel, soaking the herbs within.
