In the future city "Galaxy City", strange and murderous crimes occur frequently due to the "source of sin" left behind by the fall of the ancient gods. Yang Xue, an agent of the Strange Detective Bureau who was born as an experimental subject, relied on the "Crime Acting Sandbox" to deduce the golden finger. In the process of solving bizarre and unsolved cases such as the "Shadow Haunted House Case" and the "Blood Letter Prophecy Case", he gradually revealed the shocking conspiracy of the "Resident Soul Recovery Plan of the Strange God". From tracking down ordinary criminals to confronting those with divine blood, from deciphering secret room murders to deducing millennium secrets, the protagonist uses his absolutely rational deduction ability to become the "humanoid truth machine" to suppress the source of crime in a city where magic and science are intertwined. Finally, he completes the final deduction on the eve of the coming of the supernatural god and reverses the divine punishment with a mortal body.
