"They are dead." Bad-Breath channelled the inner gangster laying dormant within him and did the best mafia boss impression he could before destroying the communicator in a flash.
Before Arnold left the dungeon, he had quickly grabbed the communicator of the one who he thought to be the leader of the bandits. When he checked the contacts he found that it belonged to a man named Jin Rong and Zing had been desperately trying to contact the man, but obviously, Jin couldn't respond because dead people don't say a word nor do they tell tales.
Moreover, Zing's number was saved as 'Zing bro's bit*h', which meant that either the guy was related to someone important or he just hated Zing. If Arnold had seen it before meeting Zing, he would've said without a doubt that the man had a bad relationship with his friend.
