In the city of gears where magic and steam intersect, the doctor Lu Mingyuan just wants to practice medicine in a low profile. When he treated a seriously injured worker, he triggered the medical deduction system in his mind - it can simulate all treatment options, but it needs to be fueled by "the benevolence of the doctor". At the same time, Shen Qingqiu, a modern cultural relic restorer, accidentally traveled through time and discovered that the history of this gear city in the prosperous Kangxi and Qianlong periods was full of weirdness. Secret fights between magic gear sects, human body mechanization experiments, and the awakening AI in the core of the city... The two were drawn into the whirlpool, and discovered that the entire city was actually a defective product of the space-time experiment. When the whole city faced the crisis of being formatted, the only thing Lu Mingyuan could rely on was the "benevolence values" he had accumulated while treating illnesses and saving people. Can the doctor use kindness as the key to turn the gears and lead the entire city to escape to freedom?
