Gas Sensing: Molecular Cages

In 2052, smell visualization technology makes "wind" the most honest witness. Everyone's scent is a unique ID. Emotions, illnesses, and lies can't escape the molecular map. Society has entered a golden age of "absolute security". Chief Architect Shen Yan firmly believed in the perfection of technology, until a series of "sudden sudden death" cases occurred. The body of the deceased was intact, but his emotional map was wiped into a dead blank before his death. Detective Lin Xi has the ability to see with the naked eye. She captured the "molecular ghosts" that the machine deliberately ignored at the scene. When Shen Yan discovers that the sensor network he created is being used to quietly "tame" the emotions of all mankind, an even greater horror emerges: his reason, loyalty, and even trust in Lin Xi may all be "artifacts" that have been precisely calculated. This is a cage he designed himself, and he himself is the first prisoner. When the truth is only the traces blown by the wind, should he repair this perfect world, or burn it completely?
