Under the bustling city, there is a hidden mirror world that coexists with the ruins of ancient cultivation. The "Mirror Realm Administration" and the "Broken Mirror Society" who attempt to break the barriers between the two realms and release evil existences are engaged in a secret game around the broken Seven-Star Evil Lock Formation. Lin Fan, a former software engineer, awakened the Xuanwu bloodline due to an accident on the subway. He was burdened with the "Eye of True Sight" and the strange brand of the Holy Lord, and was involved in the dispute between the two worlds. He teamed up with Su Xiao, the successor of Talisman, Wang Lei, a cultivator of science and technology, and Zhang Hao, a detective with a body of blazing sun. Under the guidance of the guide Chen Mo, he shuttled and fought between modern buildings and the ruins of the Mirror Realm. He not only had to resist the erosion of thoughts, deal with the factional games within the administration, but also awakened the inheritance in the Xuanwu Trial, and used the responsibility of guardianship to fight against the monstrous conspiracy of the Broken Mirror Society, and balance the balance of order and chaos.
