There was a tone of contempt in his voice, a decidedly unfriendly attitude. Chen Kai didn't want to deal with this person, but the other party seemed to insist on harassing him, heading in his direction when Chen Kai didn't respond.
Chen Kai became wary, intuiting that this punk was looking for trouble. He snorted inwardly. Even if this kid knew martial arts, he probably wasn't very skilled. Even if a hundred of his kind attacked him at once, they wouldn't put him at a disadvantage.
This rich young master was indeed looking to start a fight. He figured that since Chen Kai looked so gentle and refined, he certainly wasn't some thug. He would definitely be able to beat him.
Plus, the security guards didn't seem to know Chen Kai, which meant that even if Chen Kai knew Qin Ying, they probably weren't close. Assaulting him would not bring any trouble.
