Pah, Su Yan is my disciple, there's no way she would betray me!
As long as she doesn't betray, there will be no problem at all.
At last, after Su Yan cleared all his lingering doubts, the Ancestor of Wu Xiang finally agreed to let her lead the Gate of Life and Death, and the Yin-Yang Door in the Yanhuang Realm.
Two identities, both important and influential, held solely by Su Yan.
Su Yan's status within the Gate of Life and Death and the Yin-Yang Door had also greatly improved.
Shortly after, the Ancestor of Wu Xiang, and the Old Ancestor of Yin-Yang himself found Su Yan, instructing her to investigate news about the Human Emperor.
This task was more important than any other. It represents the primary mission of the Gate of Life and Death, and the Yin-Yang Door in the Yanhuang Realm!
Add more roles to herself, Su Yan of course would not refuse.
More so when she found out the ultimate goal of the Yin-Yang Door in the Yanhuang Realm that bolstered her confidence.
