Ming Bu Jian is a blind masseur, but he has a sense of touch and hearing beyond ordinary people. He could hear the crack of bones from a handshake and smell the salty smell of fear from a drop of sweat. He lives in a blind massage parlor in an urban village, making a living with his hands and sensing the truth of the world with his hands.
Gu Huairen, the director of the "Ci'en Orphanage" in the city, is a philanthropist that has been reported by the media and has sponsored hundreds of orphans and disabled children. However, an old customer who was missing, Acheng, an orphan who had just graduated from Ci'en, was found dead under a bridge three days after his disappearance. The forensic doctor determined that he died of a sudden drug overdose. But Ming Ming didn't remember that Cheng never took drugs, and his fingers were as clean as him.
Ming Bujian entered Ci'en Orphanage as a masseur and provided free physical therapy to the children. In the dark world, his ears caught the faint sound of electricity coming from the basement, and his fingertips touched the unusual arrangement of scars under the child's skin. He gradually pieced together a shocking truth: Gu Huairen used orphans to conduct illegal human experiments under the guise of charity, and "Dark Pupil", a genetic modification project that allows people to see in the dark, was the end of his crazy ambition.
An invisible man wants to expose a sin hidden in the light. The invisible weapon is not his eyes, but his sense of desperate situations tempered by fate.
