On the night of the Zhongyuan Dynasty, a strange floating corpse was discovered in Luoshui, and half a piece of bronze cicada whispered "immortality", uncovering a bloody mystery in the world. Xie Qingwu, a secret agent from the Zhaoxue Division, transformed into a ghost doctor and went undercover in the ghost market, just to track down the Immortality Cult who kidnapped young adults to refine medicine. However, he unexpectedly met Lu Jin, who had been hiding for many years.
A cicada order hides a lost map, a murder case implicates the leader of the martial arts alliance, and the true identity of the protector in red is actually an innocent orphan girl. When it is difficult to distinguish between good and evil, undercover agents and traitors are intertwined. They are peeling off the cocoons in the shadows of the ghost city and the chaos of the martial arts conference, only to discover that "immortality" is a scam, detoxification is the key, and the blood debt fifteen years ago will finally be paid off in the golden light to destroy evil.
The rivers and lakes are far away, but justice will never be destroyed. The two powerful secret agents move forward side by side, using the cicada order as a guide and the sword as evidence. Amidst conspiracy and murderous intent, they uncover the truth hidden in the shadows and protect the morality of the world and the purity of the world.
Purpose: To show justice through investigating cases, and to uphold justice in the world
