Su Yanwan lived in seclusion in a small town with the "Purple Jade Light" and tried the ancient method of "taking smoke from a lamp" to reproduce the "Light Smoke Huimo". However, due to the out-of-control fire, he was choked by the thick smoke and burst into tears. Xuanjue, a secular monk who was copying sutras under the green lantern next door, heard the sound and came over. He did not hide his nose to avoid it, but looked at her embarrassment quietly. He turned around and fetched water and caramel: "Making ink is like cultivating one's mind. If you are impatient, the smoke will be chaotic." He adjusted the lamp lightly, and the thick smoke gradually became mellow. Su Yanwan was shocked by his knowledge of ink making. During the conversation, he learned that he had seen the lost ancient scrolls of ink making during his travels. After that, the two gradually got to know each other, and Su Yanwan discovered that the "purple jade light" would glow warmly when Xuanjue chanted sutras, and ink-colored phantoms appeared one after another in the town, which was consistent with the vision when Shujin Pavilion declined. Xuanjue points out the existence of "Mo Yun" and speculates that the family's decline is caused by someone coveting the "Purple Jade Light" Mo Yun. In order to find out the truth and break the prejudice that "women are not good at making ink", Su Yanwan used ink making as a guide to explore for clues with the company and guidance of Xuan Jue. In the process, she untied a double knot - she let go of the shackles of her family's decline and faced the fact that her skills had nothing to do with gender; Xuanjue also untied the knot of her past when she returned to secular life because of her persistence. In the end, the two of them discovered the mastermind behind the ink-making, and Su Yanwan regained her original intention of making ink. The "Purple Jade Light" ink-yun became the guardian of the peace of the town, and she also became the successor of the new generation of "Light Smoke Huimo".
