Dazzling

The noise of the gate shutting echoed in Kieran's ears. 

The light on the ceiling shook as if an earthquake had hit.

Heavy machinery.

Kieran's mind painted a picture of meticulous machinery closing the gate and the hidden gears in the walls and underground.

"It's even more heavily guarded than you expected, eh?"

Sitting on the only bed in the cell, Wilberst waved at Kieran, the waving motions shook the shackles on his hand, producing a rattling noise.

"Mm." Kieran nodded and didn't deny.

Everything here was indeed out of his expectations, just like Wilberst before him.

The old man was even more special than his initial speculations.

Kieran sized up the welded iron bed and eventually placed his gaze on Wilberst's old face. Compared to the last meeting, the rage and sorrow were gone, Wilberst was much more relaxed and even looked happy, much more natural as well. Wilberst also cooperated better than Kieran imagined.
