Ling Chenfeng, a graduate from an ordinary university, opened a small antique restoration shop in an old street after graduation, and his life was as ordinary as water. Until one day, when he was repairing a broken bronze cauldron, his fingertips accidentally cut it and blood dripped on the cauldron. He accidentally awakened the ancestral "Xuanmen seal". From then on, he could see spirits invisible to ordinary people and read mysterious runes in ancient books. In his eyes, ordinary cities became dangerous and full of adventures.
He helped his neighbors deal with the evil spirits that haunted him, identified spiritual antiques for his clients, and inadvertently stepped into the Taoist world hidden under the city. There are ancient families here that have been passed down for thousands of years, there are hidden masters with magic skills, and there are monsters and spirits lurking under the neon lights. Ling Chenfeng relied on his unique engraving ability and extraordinary resourcefulness to move forward step by step in the gap between Xuanmen and the city. While protecting the ordinary relatives and friends around him, he uncovered the shocking secrets of his own bloodline and the Xuanmen world. Along the way, he met partners with different personalities and encountered extremely dangerous pursuits. In the cheerful daily life and exciting adventures, he gradually grew into a new generation leader of urban Taoism.
