I am Lu Shiyan, the youngest forensic doctor at the Municipal Public Security Bureau. I can see the "death shadow" left behind by the deceased - this is a golden finger inherited from the family, and it is also a curse. My family was wiped out three years ago, and the only clue pointed to the mysterious sect "Xuanyin Pavilion". When I disguised my identity to track down the truth, I met Su Wanxing, a newcomer to the law. She was eccentric but had healing powers, and she wanted to get involved in the serial murder case I was investigating. The Xuanyin Pavilion symbol at the crime scene, the network of accomplices behind the murderer, and the intertwining of family hatred and sect disputes brought me closer to the truth step by step. But when the evil claws of "Xuanyin Pavilion" stretched out to Su Wanxing, I understood: the so-called justice sometimes requires a thought to become a devil. Only blood debt can be paid with blood to protect her.
