The elder took out a square box from behind, and the box had more than a dozen holes. He pressed the box into the groove, and a clicking sound came from inside the box, followed by a louder sound underground.
Lin Tian activated his super vision and saw the inside of the box, which was filled with countless gears. The gears interlocked with each other, forming a complex device.
Seeing Lin Tian staring at the box non-stop, the elder explained, "This box is a mechanism lock. Once installed into the mechanism hub, it can activate the manor's mechanisms."
"What if the mechanism lock breaks?" Lin Tian asked the main question, wondering if entrusting the activation of the entire manor's mechanisms to a single box might be unreliable. If the lock broke, all the mechanisms would become useless.
