Marcus secret base
Tin have been hiding in disguise very well and have been following the men's everywhere recording them in the attached camera. No one around was suspicious as he was very much careful with his action.
Following the group of men on the ground floor they went where the surveillance room was and all the illegal activities were kept under their view. All this time Tin had not seen the head of the gang which mean he was not at the base.
Reaching at the door of the room one of the man inserted a code which opened the door of the room and he went inside. Tin had been watching him very keenly and had memorize the code.
