The mechanical alert tone rang out, and the Mu Family Clan Chief's expression turned startled, with a look of confusion flashing in his eyes.

The Eye of the Sky rarely activated, but it almost always conducted simulated exercises at regular intervals.

Even the robots executing the program didn't know if it was an exercise or real combat.

Every exercise was carried out orderly, and such an incident as today had never occurred before.

Instruction release failed.

An unknown error occurred.

"What unknown error? Start self-diagnosis!" Clan Chief Mu couldn't help but blurt out.

His voice, unmasked, also reached the ears of the Seventh Prince and Gongyi Cai, among others.

The Seventh Prince looked surprised, seemingly unable to understand.

Gongyi Cai was similarly taken aback.

He had also rehearsed the activation procedures of the Eye of the Sky.

An unknown error... this was an almost impossible problem to encounter.
