Ten years after the Cataclysm, the wasteland city "Rusty Steel City" has become a hotbed of crime. Former forensic doctor Ke Luo relied on the "Skill Point System" golden finger to strengthen his reasoning ability in solving cases.

The cool points focus on the reversal of solving crimes with high IQ, the dimensionality reduction attack after enhanced skill points, and the extreme game with criminal organizations.
