Silent communication, understood only by the two of them.
Cai Mingjiao took the document bag, slightly heavy, yet she treated it as if it contained contracts of hundred billion in asset transfer, or some information.
After handing over the document bag, Qin Jin turned around calmly.
He walked up to Shi Yu and pulled a cigarette out of the pack for him.
Shi Yu took the cigarette, putting it in his mouth and squinting his sinister eyes.
Qin Jin also took out a cigarette for himself, then pulled out an expensive lighter to light it.
After taking a puff, he leaned forward, covering the other end of Shi Yu's cigarette with his hand, and lit it for him.
"The bomb will automatically detonate in three minutes."
Qin Jin kept his voice very low, unheard by anyone except Shi Yu.
To others, it appeared he was lighting Shi Yu's cigarette, but they didn't know that the two were conveying information in this way.
