Shen Yan, a modern social animal, died unexpectedly while working overtime. When he opened his eyes, he became a small policeman in Longshan County. On the bluestone slabs of the dilapidated government offices, rotting corpses lurked the danger of corpse transformation; at the bottom of the black water river outside the city, fish demons were causing trouble and kidnapped young children; in the mist of the mountains, there were even legends of immortals... This bizarre world completely overturned his understanding.
Fortunately, there was an inconspicuous ancient bronze mirror hanging on his waist - the "Qingming Mirror". The mirror can reveal the truth by looking at the past, and can also unlock cultivation techniques and evil-destroying talismans; the mirror can reveal the traces of monsters and track them, opening a way for him to survive in a world full of dangers.
Starting from dealing with a mutated corpse, Shen Yan relied on the power of Qingming Mirror to gradually uncover the strange secrets of Longshan: the mysterious force behind the fish demon, the underlying reasons for frequent corpse transformations, and the true purpose of the rumored immortal's seclusion... As a policeman, he must not only protect the people, but also pursue the path to immortality. Let's watch Shen Yan holding a mysterious mirror in his hand, singing and walking, and in a world where demons, corpses and immortals coexist, he will create his own legendary path.
