Critical Frequency: Grid Pulse

Fifty Hertz is the heartbeat of this city. Every line, every light, every server breathes quietly on this frequency. Futures trader Xie Zhonghao can read this breath. Many years ago, he gave up the superconducting energy storage project and turned his lifelong profession into flying numbers on the trading board; his fourteen-year-old son was diagnosed with electrosensitivity syndrome and has since been imprisoned in a thin shielding net. Until the frequency of the power grid began to be adjusted by an invisible hand. Computational load, harmonic distortion, low-frequency oscillation - a critical point called "computational electrical resonance" is approaching. Beyond it, the city's AI will collectively lose consciousness; and the key to that critical point happens to be hidden in his son's brain. Whoever controls the frequency controls AI, controls the computing power, and controls the entire digital world. This is the story of a father playing chess with an invisible opponent on the battlefield of electricity.
