Wei had just found a way to modulate the global discharge cycle to resonate with the Schumann resonance—the Earth's own electromagnetic heartbeat.

He didn't try to hack the monitor's main processor. That was too obvious. Instead, he tapped into the service port—a tiny, unpopulated 4-pin header on the driver board he’d found in a service manual PDF online.
