The mechanical prompt sounded, and Old Patriarch Mu froze, a baffled look flashing through his eyes.
Sky Eye rarely activated, but it conducted simulated drills almost every so often.
Even the robots executing the procedures did not know whether it was a drill or a real battle.
Every previous drill had proceeded in orderly fashion. Nothing like this had ever happened.
Command issuance failed.
Unknown error detected.
"What unknown error? Begin self-diagnostics!" Old Patriarch Mu blurted out.
He made no effort to conceal his voice, and it reached the ears of the Seventh Prince, Gongyi Cai, and the others.
The Seventh Prince looked astonished, as if he could not understand.

Sky Eye was a self-contained system, unconnected to any other network, and it constantly conducted self-checks and inspections.
The robots aboard Sky Eye were also the latest generation, with an error rate far lower than that of humans.
Most importantly, Sky Eye stood high in the heavens, like lofty barriers in the sky.
