The next morning, the two men go to the lake to bathe. The elder man notices that the lake is full of ancient treasures, and he decides to dig them out first. He wonders if the lake once belonged to the ancient civilization of cultivation, but the elder man assures him that it is only a matter of time before some reclusive cultivators populate the lake. He also tells the younger man that he can imagine how many ancient treasures he would have missed if he hadn't become a cultivator. He then tells the older man that the man's grandfather gave 20,000 yuan to a temple merit box, and that the young man then went down to the mountain to visit his grandmother and sister. The older man is impressed by the old treasures and decides to use them to help his grandmother's health. He adds a splash of water and some ginseng to the water, and says that he'll use alchemy to refine the old treasure. The younger man is amazed at the speed with which he can refine the ancient treasure. He compares it to alchemy's "universal good fortune" and says he's going to use it to clear out his body's impurities. He notices that his body is sweating, and the smell of sweat and odor is coming from his body. He's worried about the side effects of the ancient treasures. He decides to try to purify the water by using alchemy.
