Beneath the glittering facade of the modern metropolis, a battle of astral spirits that will decide humanity’s fate is quietly unfolding. Ling Chen, founder of an AI company, unexpectedly awakens a data astral spirit. He encounters eleven astral-spirit bearers from different fields, including special police, forensic medicine, jewelry, law, and broadcasting. Recruited by the mysterious organization Xuanchensi, they join forces to repel the invasion of supernatural organizations from Europe and America. By day, they use their professions as cover to resolve supernatural incidents and maintain public order in real-world settings such as tech parks, shopping streets, jewelry stores, and hospitals. They also venture into mythic ruins like Kunlun Xu and Guixu to uncover the origins of the astral spirits. From awkward first encounters to standing together through life-and-death battles against traitors within their ranks and powerful enemies from beyond the borders, the twelve grow through the fusion of ancient martial arts and supernatural abilities, and find strength in the bonds of love and friendship. When the Overlord from Beyond attempts to destroy Earth, they will form the “Twelve Astral Spirits Guardian Formation” and write an astral legend for their age, where the modern city meets mythology.
