Admiring the fake identification card for a while, Shi Tian then stored it in his pocket. 

He didn't plan to store it in the Dimension Ring when Mary was present and watching him.

A Dimension Ring looked no different than a normal ring accessory. 

Thus, unless one took a closer look and inspection on the ring, there was no way others could discern it for being a Dimension Ring.

"Alright then, since there's no problem with the identification card, follow me," Mary said, turning around and exiting the apartment complex.

Closely following right behind, Shi Tian arrived outside and saw Mary opening the door of an armored-truck-like vehicle. 

"This is-" Shi Tian glanced at the armored truck in a daze, clearly not expecting her to arrive here with such a vehicle.

Seeing the astonished look from Shi Tian, Mary chuckled softly from the driver's seat.
