The imaginary city "Yunzhou City" has flashing neon lights on the surface, but in fact there are undercurrents. Thirteen dusty unsolved cases shroud the city like fog. Shen Jinghan was a seemingly ordinary restorer of ancient books, but due to an accidental interpretation of ancient books, he was involved in a bizarre case that spanned ten years. The half-volume fragment of pages in his hand turned out to be the key clue connecting all the unsolved cases. As the investigation deepens, dusty memories and hidden identities gradually surface - he seems harmless, but behind him are huge family secrets and unknown strength. The mysterious family elders secretly escorted him, and the extraordinary Fa Xiao guarded him closely. Even his opponents whose identities were a mystery looked at him differently. Every time you get close to the truth, there is a fatal danger; every seemingly irrelevant detail hides an amazing foreshadowing. Behind the unsolved case, is it the distortion of human nature or the game of power? Under the protection of everyone, Shen Jinghan peeled off the cocoons and uncovered the truth of the fog-locked city step by step, but found that the end of all cases pointed to a shocking secret that was closely related to himself. He must find a balance between protecting himself and protecting those around him, and carve a path to the truth in the fog.
