บท 222: Communication Signal

In the interior of the Iron Sentinel, Shi Tian took off his mask as he revealed a confused expression. 

He didn't know why Mary wanted to drag him away, given that they were still in the midst of a discussion regarding the plan.

"Is there an urgent matter?" Shi Tian asked calmly, waiting patiently for Mary to explain her action. She must have had her reasoning for doing so. 

Mary nodded after a brief moment, her expression serious. She, too, removed her mask and reached for a button on the control panel within the Iron Sentinel.

With a deft touch, she activated the encrypted communication channel. 

This channel was reserved for confidential matters, typically used by high-ranking officers or individuals with sensitive information.

Once the channel was secured, Mary spoke in hushed tones. "Nathan, there's something I need to discuss with you privately. It's a matter of utmost importance, and we can't risk it being overheard."
