On the C-17 transport plane, Lu Yao leaned back leisurely in the cabin, waiting for the nearly twenty-hour flight to end.
If it weren't for the 40KG "shackles" on his body, he would have looked as if he were on vacation.
This fixture was no ordinary one, with its silver-white body reflecting a metallic chill, and a constant green light on it.
It was a proximity sensor, ready to release a high-voltage current instantly if he went beyond the limit, enough to shock someone into immediate unconsciousness.
The current could also be triggered by a remote control device or a voice control device.
Moreover, this gleaming silver instrument was equipped with a "magnetic lock" function.
At the moment, it was generating a powerful magnetic force, firmly adhering Lu Yao to the transport plane's cabin wall, rendering him immovable.
The five SEAL team members escorting Lu Yao had great faith in this high-tech "shackle."
