Just after dusk, the Mutant Winged Dragon had led his group away. Once the Mutant Winged Dragon left with his people, Qiao Fanfeng hurriedly sought out Guo Mingyu. They didn't know whether the Mutant Winged Dragon planned to return to Dragon Slayer Island or had a different target in mind.
Whether they genuinely wanted to go back to Dragon Slayer Island or had chosen another target, or even devised some other scheme, the people of the Immortal City couldn't allow the Mutant Winged Dragon to leave with the members of the Dragon Slaying Clan. As long as these people existed, they would be a menace, possibly returning at any time to wreak havoc on the Central Plains or potentially choosing a different target and plot.
