Wulongshan Gynostemma pentaphyllum admired the Nanyan young man who became a god after practicing, so he devoted himself to practicing for thousands of years and transformed into a human form, named Lanjiao. She was brought back to Nanyanshan Village by Zhang Yunsheng, the wine-making successor. With her knowledge of medicine, she was able to treat the villagers' illnesses and get along well with each other. Later, the village was attacked by a plague, and there was a man in black behind it. Lan Jiao asked for help from a young man who had become a god, but was refused the invitation to ascend. The villagers were bewitched and thought of the strange color of his blood as a demon and wanted to burn him to death. Lan Jiao refused to abandon the villagers, and burned thousands of years of Taoism to turn into ice crystals to absorb the filth and save the village. In the end, with the help of gods, she was reborn and became an immortal. Zhang Yunsheng often told people about this strange fate.
