Main plot: Lin Yu, a modern-day quipster, transmigrates to an immortal-cultivation dynasty after a car accident and binds himself to the Crime Deduction System. Serving as a judicial officer, he solves Heavenly Law Crimes and outwits the three-way struggle for power among the government, sects, and imperial court. Using modern forensic methods, he dismantles the monopoly over cultivation resources. As he investigates cases such as the Foundation Establishment Pill Murder, the Secret Realm Life-Draining Case, and the Dragon Vein Blood Sacrifice Case, he gradually uncovers the dynasty's true nature: cultivation is exploitation. In the end, he uses the System's black box to challenge the laws of Heaven and establish a new order that fairly distributes spiritual roots.
