After Zhouyang left the Yellow Sand Sect, he didn't return directly to the Yuquan Lake Oasis or Red Fox Ridge, but instead went to the Baisha River Oasis.
His purpose for going to the Baisha River Oasis was, of course, to visit Chen Ping'an at White Camel Peak.
Now that the Chen Family Ancestor had fallen at the hands of a demon beast, and the Zhou family gained the Red Tiger Mountain Oasis gifted by Cao Wenjin as a foundation, the root of the conflict between the Chen and Zhou families no longer existed.
Moreover, the Chen family, now one of only two Purple Mansion Clans in the Boundless Desert Sea Cultivation Realm, was an important force that could not be ignored by any side in the now turbulent Boundless Desert Sea Cultivation Realm.
Zhang Yunpeng had subtly indicated to Zhouyang as he left the Yellow Sand Sect that it would be best for the Chen and Zhou families to resolve their conflict and join the Yellow Sand Sect's camp.
