In order to avoid ending up like the Ghost King and the others, Ling Feng felt it was time to retreat for secluded cultivation; his Early Divine Realm cultivation wasn't enough to stand out in this world.
Ling Feng had become the master of the cave abode, and he could now enter the cave at will. So Ling Feng simply brought the three Ghost Kings to appear near Blood Howl City.
"You must be careful with the tasks I've instructed you to do; do not show any flaws!" Ling Feng said sternly, "And remember, do not contact any experts above the Azure Sky Realm, remember!"
Although the Ghost King and Shen Yu didn't understand why the master added this line, since it was the master's order, there must be a reason, and they just needed to follow it.
As for Hai Canglang, he stayed in Blood Howl City to assist Ling Feng in handling the city's affairs.
