Ye Xiao knew that Wu Shuang thought of him as a member of the Immortal Heaven Sacred Land. Wu Shuang didn't know that Ye Xiao was actually the one who destroyed the sacred land that he had founded millions of years ago. Well, Ye Xiao also didn't tell him. There was no reason why he should tell Wu Shuang about the destruction of the Immortal Heaven Scared Land.
Ye Xiao let Wu Shuang think he was an important member of the Immortal Heaven Sacred Land and the treasures had fallen into the safe hand. With this, Wu Shuang happily left this world.
After Wu Shuang's Divine Soul disappeared, Ye Xiao looked at the Freezing Sky Sword. Then he shifted his gaze slightly and saw a milky white bead the size of a fist not far from the Freezing Sky Sword.
This was the Divine Soul Bead that Old Monster Yan had gotten from the Abandoned World of the Divine Realm.
