Back in Wangshan City, Sang Que had once used the Yin Child's Ghost Eye to see scenes from Yu Da's past.
She knew that Yu Da's hometown had suffered a famine, and it was during that time that Yu Da tamed the greedy ghost within him and became a Yin Walker.
At the time, Yu Da was still very young and couldn't control the greedy ghost; he was also very scared.
But Yu Da was very fortunate to meet Wu You, who was in fact Sang Que's biological mother. She used the name Wu You in the Deceit Dynasty.
In the exploration with the Ghost Eye, Wu You's appearance was unclear, likely difficult to see clearly by any other means as well.
