A dusty notebook drags people from two eras into the same abyss. In 2023, college student Lin Jian created a suspense novel of the Republic of China based on his grandfather's relics: the son of a wealthy businessman disappeared mysteriously, leaving only an ancient jade cong at the scene. Gu Yunshen, the brilliant and resourceful consultant in his novel, is peeling off his cocoon. However, a mysterious netizen named "Gravedigger" kept sending corrective private messages, and the details were so real that it was horrifying - as if that person had seen it with his own eyes. 1928, Jiangcheng. Criminal investigation consultant Gu Yunshen stood at the strange crime scene and picked up a piece of blue brick debris that should not have been there. This fragment points to the family taboo that he, as the descendant of the "Guanshan Taibao", is sworn to protect to the death. Su Wan, an archeology assistant who has returned from studying abroad, takes the initiative to approach her. Her purpose is by no means simple. Behind the smile of Shen Shijun, the president of the Chamber of Commerce, is a century-old conspiracy called the "Eternal Life Society". All of them are pursuing a legendary secret - the "Dragon Bone". When the plot written by Lin Jian began to resonate strangely with reality, and when the clues discovered by Gu Yunshen suddenly pointed to bizarre cases in modern cities... The boundaries between dual time and space suddenly blurred. Who is using novels to convey messages that span hundreds of years? Is the "Dragon Bone" a valuable treasure that can reverse destiny, or is it a curse that brings disaster? At both ends of the screen, Lin Jian, who writes the novel, and Gu Yunshen, who pursues the murderer, what roles do they play in the maze of blood and time and space?
This is a series of puzzles that started in the Republic of China, and it is also a self-salvation that ended in modern times. When the truth emerges one by one like a keel, only the unfinished love and protection deep in time remain unwavering.
