Alex only realized that Pearl had been taken back to the Western Continent the day they had returned by Bai Jingshen when he searched for him so he could take him there.
Alex left on his own, even though his subordinates didn't want him to, and quickly flew toward the Southern Forest where the White Tiger's palace was.
He arrived at the formation and was quickly led to Bai Jingshen. After telling Bai Jingshen the reason he was there, he was quickly led to Luo Beihan, Bai Jingshen's 6th wife. That had come as a surprise to Alex when Bai Jingshen told him that.
Wen Meirin, Luo Beihan, and Pearl's great-grandmother, Ren Xiao were initially just concubines. However, after Pearl's ascension to a White Tiger, Ren Xiao needed to be given a better status in the family. Bai Jingshen knew he needed to make her a wife as well, but didn't want to let the other two down, so instead he made everyone his wife.
Now, he had 7 wives and no concubines.
