In this chapter, we learn that Lin Jinhong has obtained a "perfect body elixir" , which is a kind of holy substance that can heal the body and heal the soul. We learn that alchemy is a branch of medicine that deals with the body's natural healing powers. In other words, alchemy deals with healing the body from the inside out, not from the outside in. This is because the body is made up of many parts, and the healing powers come from many different parts of the body. Thus, it is impossible to cure the body of its defects.
