During the Apocalypse, Jinyiwei Lu Shenzhou, a cold-looking case-handling machine, suppressed the guilt of his family for three hundred years, and was ordered to investigate the human sacrifice case in the southwest "Demon Town". The Wuxian Kingdom, which cultivates immortal civilization, is on the verge of collapse due to excessive extraction of the earth's spiritual energy. Saint Yunyao volunteered to become the "Eye of the Formation" and has omniscience in the formation. She became the last saint of the Wuxian Kingdom, the "Earth Mother Empress" of Guixu Town. The saint hated the people in the court and condoned the small town's sacrificial practices and confronted Lu Chenzhou. Lu Chenzhou discovers the conspiracy of the current dynasty. The national master Xuan Weizi is a descendant of the traitor Xuan family in Wu Xian. He wants to seize the formation and make elixirs for immortality. He knows the secret of Guixu Town and secretly supports the living sacrifice. Lu Chenzhou sympathizes with Yun Yao. A disciple of the Imperial Master assassinated Lu Chenzhou, and Yun Yao forcibly transformed into a human being for three days to save him. Lu Chenzhou fell in love with Yun Yao. Lu Chenzhou has shouldered the guilt of his family for three hundred years. As the ninth generation descendant of the Lu family and with the "bloodline of breaking the formation", he went through life and death to break through Wu Xianguo's "Return to Ruins" and rescued Wu Xianguo Yunyao. Yunyao was reborn as an ordinary woman and stayed with Lu Chenzhou.
Purpose: The selfless Jin Yiwei Lu Chenzhou investigates the case and discovers that his family owes three hundred years of debt. He makes an exception for himself. The imprisoned saint waits for the only person who dares to fight against the whole world for her.
