The monk explains that alchemy is a form of medicine that uses the spiritual energy of the body to make pills out of it. He says that the pill that he saw that day was made of the same spiritual energy as the one he saw in the previous day. The monk says that he will teach the monk how to make magic pills, but first he wants to know what the doctrine of alchemy is. He knows that alchemy cannot be practiced simultaneously with martial arts, and that if a person wants to become an alchemist, he must give up his current occupation as a warrior. He will make the monk the first person in the world to cultivate both martial arts and alchemy, and if he fails, all his martial arts will fall short. He asks the monk if he knows the buyer of the pills, and the monk replies that he does. He then asks if the monk knows that the buyer must be a disciple of his sect. He tells the monk that the fire that the monk uses in alchemy is made by converging his mental power. The spiritual energy in the air, he says, can be divided into many groups. For example, the fire of the secret realm is made of fire, the aquatic spiritual energy is made up of water, the metallic spiritual energy comes from the mountains, and so on. He wonders if the buyer is a heaven-chosen person who has the woodsy characteristic.
