Chu Heng, an ordinary data maintainer, accidentally awakened to the "Ethical Judge System" and was able to see through the prejudice and injustice hidden under the cold code of AI. From gender discrimination in AI recruitment to regional exploitation of urban traffic AI, he discovered that beneath the bustling surface of smart cities are layers of digital slums and the sacrificed weak. The system gave him S-level talents and correction abilities, but it also brought about mental drain and crazy counterattacks from interest groups. Facing the "efficiency-first" bureaucracy and capital, Chu Heng gradually grew from a passive little person to a special examiner of the Federal AI Ethics Review Bureau. He uses the system to expose the truth, correct loopholes, stand side by side with his allies, and use code to fight for human ethics. However, every victory pushes him into a deeper conspiracy... This war about intelligence and ethics has just begun.
