The Chi family has inherited the mission of collecting relics from generation to generation. By the time Chi Yu, who is twenty-eight years old, has already integrated into modern fireworks. During the day, he is a gentle and rational civil lawyer in Cangcheng Law Firm, dealing with legal principles and human relationships. At night, he is a scavenger guarding a thousand-year-old heart watch, following the spiritual breath of strange obsessions, traveling through the world and passing through mental tribulations. There is an ancestral saying: Only guide the way, not force the crossing. Crossing people first crosses the heart. He has seen lonely souls who are sick with longing, travelers who feel guilty and troubled, and travelers who are trapped by trauma. He uses spiritual power to open up the illusion of obsession, and helps everyone trapped in their inner demons face the past and reconcile with themselves. The legal principles uphold justice in the world, and the spiritual power can overcome the ups and downs of people's hearts. He upholds the millennium inheritance, and serves as the gentlest guide in the world among the lights of thousands of families, writing all the obsessions and redemption in the world of fireworks.
