Quadruple Conspiracy: the Thirteenth Floor Secret Room

In 2035, when smart homes are popularized, Nebula Apartment stands in the center of the city. This is a 32-story high-tech smart apartment. Each room has an independent smart system. The 13th floor is "hidden" on the electronic display. Lin Mo, a former criminal police officer, is now an auditor of intelligent systems. He resigned three years ago because he failed to solve the secret room murder case. Fiancée Chen Yu died in a secret room in Xingyun Apartment. Surveillance showed that she committed suicide, but Lin Mo firmly believed that it was murder. Three years later, another secret room murder occurred in Xingyun Apartment. The deceased, Li Xue, 27 years old, suffered mechanical asphyxia. The smart door lock was locked from the inside, the surveillance video stopped working the moment the deceased entered the room, and all the alibi were perfect. As a system auditor, Lin Mo was called by the police for investigation, but found that this case was surprisingly similar to the death method of his fiancée Chen Yu three years ago. Access control records, surveillance videos, smart system logs - all electronic evidence points to one conclusion: this is an impossible crime. But Lin Mo doesn't believe in "impossible". He began to investigate in depth, but found that this seemingly perfect smart apartment hid the secret on the 13th floor. This secret is closely related to the death of his fiancée Chen Yu three years ago, and to a mysterious project called the "Phoenix Project." As the investigation deepened, Lin Mo discovered that behind all the cases, there was a common goal - consciousness uploading. Some people are exploiting loopholes in intelligent systems to collect human consciousness data in an attempt to create "digital immortality." The murderer may be Lin Mo himself.
