Li Zhongweng had a tumour in his nose. As big as a walnut, he feared it would gradually increase in size, and tried many methods to treat it, but without effect. Arriving at a guesthouse in Xiangyang, he encountered a Daoist and they drank together happily, passing the cup day and night. When they were about to part, the Daoist took out a small gourd, about as big as a jujube, and poured out three millet-sized grains of medicine, giving these to Zhongweng and saying: “At night you should puncture the root of the tumour with a needle, and stitch the medicine into this needle-hole; the next day the tumour should fall away. The other two grains are to treat strange illnesses.” Zhongweng used the needle as instructed. By midnight, he felt the medicine moving around the base of the growth and twisting around. When dawn arrived he touched it, and found that the tumour was already quite gone. Hurrying to a mirror to examine his face, he saw that there was not even a scar. He therefore marvelled at the miracle, and kept the remaining grains secret. When his young daughter fell over and broke a tooth, he placed one of the medicine grains in the tooth root, and after an evening her teeth returned to their even shape. He took a liang (31.25g) of mercury and placed it on the blade of a hoe, then put the last grain on this, at which it transformed into the finest quality gold. He then understood that these were pills of the Great Elixir smelted by the immortals.
