Lin Mu and the group searched far into the west, for any signs of Yao Changying and her people. But they found little after the third offering hall.
There were some scattered traces of Withering Dao but they were far too part to tell a pattern, or hint at where they might have come from. As such, all they could do was to throw a wide net and search every place possible.
Two months went by like this, during which the group continued to hunt as many Chimeric Beasts as possible and grow their stores of credits. They did find a fourth Offering hall in this period too, but there were no signs of the Black Fish island members or Yao Changying being there.
The entire offering hall had been surrounded by two barriers, just like the very first one Monk Hushu had encountered. They even scoured the area in detail over and over, just to make sure they hadn't missed anything, but there truly was no sign of Yao Changying or her people.
