In 1928, Tianjin Wei. Detective Lu Zian, a descendant of a martial arts family who returned from studying in Japan, was disheartened by the mysterious case of his master's family being wiped out three years ago. He hid in the edge of the concession and ran a second-hand bookstore. When a series of murder cases imitating folk ghost stories and using strange techniques occurred one after another - "Fox Fairy Seeking Life", "Revenant on the Stage", "Mummy Walking at Night" - he was forced to return to the world and partnered with the new female forensic doctor Shen Moshu.
The two relied on the intuition of ancient martial arts and the rationality of modern science to clear away the layers of fog, only to find that behind each case, there was a vague point to a secret organization "Zhen" that believed in "chaos is order", and the clues were closely related to the tragic death of Master Lu Zian. The seven serial strange cases are actually a huge conspiracy against him and the city.
This is an intellectual contest between reality and legend, a perfect synergy between martial arts and science. On the mixed and bizarre stage of Tianjin in the Republic of China, explore the real people's hearts behind the shadows and unravel the chronic diseases in the torrent of the times.
