Chapter 153: Spy

After sending Derek an encrypted message, Mary smiled briefly. 

'Heh, if Hank knew his right-hand man was someone of the Shadow Legion and a spy we placed. I just wonder how much shock he would receive.' Mary thought to herself. 

Throughout the years, when Heaven's Mecha kept attacking their Optic Mech, they might seem dormant but were secretly implementing many people into them.

And this was merely the start of their retaliation.

While Mary was thinking about the past and the number of grudges they had with Heaven's Mecha, she heard someone shouting for her name.

"Mary!"

"Mary!"

"Huh?" Snapping out of her daze, Mary turned and looked at Shi Tian. 

"What are you shouting at me for?" She asked, clearly irritated by his tone. 

"You were the one that told me to call you when I'm done with the workout." Shi Tian said with a deadpan expression.
