In the deserted post on a rainy night, a seemingly ordinary ritual of salvation allowed Chen Qing, the descendant of Nanmao, to glimpse the bizarre "reality" in his right eye - the cold and rotating black runes, and the dark red resentment wrapped around countless painful faces. From then on, the forcibly opened yin and yang eyes and the burning pain of the ancestral "stone soul" reminded him all the time that the operation of the world was far from simple as it appeared.
He is forced to form a strange alliance with Bai Xiaoqi, a disciple of Bei Ma who seems to be greedy for money, but actually values love and justice; Zhang Yi, a hard-core detective who believes in materialism and tries to use science to record abnormalities; and Wu Qingyuan, a scholar who is knowledgeable and memorizes and is obsessed with folklore secrets.
From the funeral parlor where evil objects are refined to the mist-shrouded tomb, from the dark web death game to the ancient voodoo in western Hunan, they follow the clues and gradually come into contact with a huge organization called "Shadow Alliance" and the terrifying goal it pursues - using the scattered "Netherworld Contract" as the key to extract dragon veins, subvert the present world, and build the so-called "new world" in the ultimate chaos.
Traditional magic collides with modern technology, and faith and desire confront each other in the gray area of good and evil. This is a journey of protection and sacrifice. They must struggle forward amidst their own trauma and endless treachery to prevent the impending doomsday catastrophe.
