章節 228: Drones

The transformation of the interior of Iron Sentinel remained unknown to the exterior. 

In fact, the Iron Sentinel on the outside remained perfectly still as it was, but the truth was far from that.

There were a few shaky moments and the interior of the Iron Sentinel was rapidly changing from a normal storage and roomy compartment to something akin to a lab environment. 

For some reason, Shi Tian felt a bit terrified by the lab scenery but was quickly pacified due to his passive ability. Nevertheless, there was clear discomfort on his face no matter how calm he was.

Naturally, with the keen eyes of Mary, she noticed Shi Tian was feeling somewhat uneasy at the transformation. 

"Is there something wrong, Nathan?" She asked softly in concern. 

Never once had she seen him acting so abnormally. Not even when they were being ambushed by the Moles or the Night Intruders. 

Meanwhile, Shi Tian scratched his head and smiled sheepishly.
