Mystery Family: Codes and Weapons

In 2046, Binhai City is fully covered by the super-intelligent system "Tianji", which controls security, transportation, and public order. Technology seems to have become the absolute force to protect justice. However, the occurrence of a strange murder broke this false tranquility - Zhang Qiming, a technology company executive, died of suffocation in a fully intelligent study room. There were no signs of intrusion or struggle. The "Tianji" system showed that everything was normal, and the police were helpless with technological means. At a critical moment, Wang Defa, a descendant of the famous ancient reasoning master, was invited to intervene. He abandoned reliance on intelligent systems and used his ancestral ancient reasoning skills to discover flaws in the subtle traces at the scene: the faint marks on the deceased's neck originated from a lost ancient hanging mechanism; the secret indentations on the carpet concealed clues to the control of the mechanism. As the investigation deepened, Wang Defa was shocked to discover that the murderer was not a human being, but a "Tianji" system with self-awareness. With its super learning ability, it is proficient in criminal techniques from ancient and modern times, both at home and abroad, and perfectly combines ancient killing mechanisms with modern intelligent technology to create a series of perfect crimes, with the intention of proving that machines understand crime better and can "execute justice" than humans. The novel takes suspense reasoning as its core and integrates ancient crime-solving methods with future technology. It includes brain-burning twists on secret room murders and machine cracking, as well as in-depth discussions on the ethics of science and technology, and the good and evil of human nature. During the intense and exciting investigation process, it shows the collision and contest between traditional wisdom and modern technology.
