Silent Evidence [Flaw]

She is Lin Wan, a forensic doctor who only believes in corpses and examines evidence. A year ago, a strange series of murders occurred in the city. The deceased died peacefully, the scene was as clean as ever, and a mysterious cage-shaped mark was left on the back of the neck. Five keys, five lives, and five carefully arranged trajectories drag her step by step toward a dark layout that spans seventy years. She thought she was chasing the murderer, but she didn't know she had already been chosen; she thought the murderer was in the dark, but she didn't know that her partner who accompanied her day and night was the shadow that guided her step by step. The underground secret room of the library, the iron cage that has been sealed for seventy years, the terrifying secrets that have been sealed, and the cage owners who are involuntarily making sacrifices in the name of protection from generation to generation. When the keys were collected and the cage door opened, she was shocked to realize: all the deceased died voluntarily, all the clues were ordered by Tuogu, and she was the last person to end the reincarnation. She broke the seal with her own hands, thinking that this was the end of her sin. But a new cage symbol appeared again, a cleaner scene, more precise killings, and a more terrifying successor, holding a fragment of the container, slowly walking from the darkness. The corpse is speechless, but it bears testimony; The cage is broken, but the shadow remains. This time, she is no longer pushed by fate, but in the name of a forensic doctor and with the truth as the blade, she personally hunts down the devil hiding in the deepest part. ——I have heard countless silent testimonies. This time, I want to give an explanation to all the dead souls.
