When Mary proclaimed the content inside to be boosters, Shi Tian held an extremely doubtful expression. After all, Shi Tian couldn't comprehend how and why these metal suits are called boosters.
"Do you not believe me?" Mary asked when she sensed his doubtfulness.
Shi Tian shook his head.
"Why wouldn't I believe you, Mary?" He quickly said, feigning innocence.
"Tsk, just watch carefully, and don't beg me if you want to put it on." Mary clicked her tongue and snorted. She knew he wasn't being honest, given that he didn't seem excited about the boosters.
Thus, the only way to clear his doubt and shut him up was to prove it directly.
Interacting with him for quite a while, Mary had already grasped what type of person Shi Tian was. He was the practical type instead of the theoretical type, meaning unless he witnessed something personally. It would be hard for him to place his trust in it.
