One hundred thousand years ago, the immortal world was in chaos and many gods fell. A book of life and death with hidden mysteries fell into the human world. During a scientific expedition, the young archaeologist Lu Yun accidentally broke into a tomb whose age could not be identified at all. His peaceful life was broken and he began a thrilling journey of searching for various mysteries. Lu Yun, who was dragged into the fairyland by the heavenly book, took charge of Xuanzhou City as the governor of Langxie Tianxuanzhou. He encountered the first problem as soon as he arrived in the fairyland. Lu Yun's term of office was about to end, and the major families in Xuanzhou were eyeing the position of governor. In order to continue to serve, Lu Yun, who was unable to practice, took his female servant to sneak into the tomb of Xuanchi Mountain to find the Nine-orifice Golden Pill that could change his physique. In order to avoid the conspiracy of his enemies, Lu Yun and the female servant sneaked into the depths of the tomb. The master and servant encountered the pursuit of the thousand-year-old corpse monster, swarms of corpse flies, and the weird stone spirit. After that, they accidentally hid in a woman's boudoir full of fragrance. The woman in the portrait was as beautiful as a fairy. Lu Yun subconsciously touched her and stimulated the power of the Book of Life and Death in his body. Who knew that the woman in the portrait was the Danxian Yuying, the governor of Xuanzhou in the previous term, and the first reincarnation messenger recorded in the heavenly book. With the care of the Danxian, Lu Yun successfully changed his physique and temporarily saved his identity through negotiations with the Emperor of Langxie. He thought that the matter had come to an end. Every night, Lu Yun can see some fragments in his dreams that do not belong to his own memories. Once, Wan Feng entered Lu Yun's room and saw the heavenly book in the sleeping Lu Yun's body shaking wildly, accompanied by the strange sight of nine dragons carrying a coffin around him. In order to solve the mystery of the heavenly book, Lu Yun went to Xuanshui City adjacent to Xuanhe River to find out the truth according to the hints in the book. At this time, it was the Xuanhe Festival. The sacrifice of living babies that lasted for a hundred years had made Xuanshui City dead. The people tried every means to hide the young children in the dark room, and the swaddled babies were put in wooden boxes covered with thick cotton. To save the children, Lu Yun had to sneak into Xuanhe River to find out. The devastated Xuanhe Water Palace had long been occupied by the Gandharva monsters hidden in the darkness. Before Lu Yun and his companions could escape from the shocking group of monsters, they were attacked by the demonized Xuanhe River God. In order to save his companion Qing Han, Lu Yun used the Floating Life Map as a weapon, forced out the power of the Book of Life and Death in his body to subdue the River God, and gained a new skill. So far, Lu Yun has subdued the fourth reincarnation messenger, and each reincarnation messenger represents the strongest in different aspects such as talismans, martial arts, formations, and refining. Lu Yun is getting closer and closer to the truth of the Book of Heaven, even if he is against the world and the four seas. At this time, the Curse King sitting on the Ninth Heaven looked at Lu Yun and smiled: "Humph, an ant who overestimates his own abilities..."
