As soon as the new Henan City God Song Tao took office, he found that the order of the underworld was shaken. The book of good and evil in the Tang Dynasty was tainted. The innocent soul of Chang'an Wangyoufang, Nie Yiguang (the predecessor of Nie Xiaoqian), wept for help, which involved the secret murder of Prime Minister Changsun Wuji. The soul of Song Tao travels through time and space and possesses the dying body. In Chang'an, the prosperous Tang Dynasty, he faces the evil magic of tree demons and the conspiracy of powerful people, rescues the wronged soul, and obtains the first token - Xiaoqian Lantern.
However, the chain of cause and effect is increasingly broken. In Lin'an in the Southern Song Dynasty, human skin lanterns brought disaster to the world, and the fox demon Hu Meier wept and accused the Qin Party of corruption and soul refining; in Shandong in the late Ming Dynasty, the assassination case was tragic, and the Zhonghun Banner wept in the blood mist of Shanhaiguan; in Zichuan in the early Qing Dynasty, the story of "Liao Zhai" turned into a nightmare that swallowed reality, and the water god mirror was trapped in the sea of resentment of the literary prison... The mastermind behind the scenes, the "Shadowless Demon Lord", corrupted people's hearts with thousands of years of resentment, trying to subvert Yin and Yang.
In order to repair the broken cause and effect and protect the order of reincarnation, Song Tao carried the four dynasty tokens of Xiaoqian lantern, woven jade, loyal soul flag, and water mirror. Under the guidance of Pu Songling, he traveled through the underworld and the human world in the Tang, Song, Ming, and Qing dynasties. He catches murderers and solves cases, saves the souls of wronged people, faces the filth of the prosperous times and the tragedies of the troubled times, gathers the souls of heroic spirits such as Yue Fei and Gongsun Jiuniang, and gathers all the people's meager good thoughts as lamp oil. In the end, the "Lamp of the Heart" was rekindled on the top of Mount Tai, using the light of people's hearts to be good to fight against the Demon King of Chaos, engraving the belief that "the way of heaven is the people's heart" into the monument, and protecting the lamp that shines brightly through the ages.
The way of heaven is in the human heart, and the way of heaven is the human heart. As long as there is a light on in this world, good and evil will not be lost, and cause and effect will not be broken. "
