Anyone smart enough to be a security guard at a medium-sized company should not be a fool, nor should they lack perception.
"Okay, you all stay here for now, and I'll go inside to make a call," said the security guard indifferently, leaving the words behind before returning to the security room and shutting the door.
Seeing the guard's actions, a glint of light flashed through Tangyu's eyes because he had seen that the guard didn't actually make a call upon returning to the security room but instead picked up a newspaper to read. In other words, the guard was obviously brushing him off, ignoring him outright. A company's security would never be of such low quality; even a fool could see his own background and would definitely not refuse entry without even asking. Therefore, there must be some hidden reason behind this, and the guard must have been acting under orders from above; otherwise, he would never dare to act this way.
