However, the shock and tremors had alerted even the dullest person in the crowd, let alone Lin Fan and the individuals he suspected.

The couple he had his eyes on instinctively lowered their stance while their hands reached for their waists.
Lin Fan took note of their behavior. Only those trained in firearms under stressful conditions reacted like this. It was as if the two were reaching for nonexistent guns.
Although they retracted their hands later, realizing their weapons weren't with them, he was certain they were extremely accustomed to carrying firearms.
