The red-haired lady told Zhang Tao about Ye Xiao. She also told him the series of events that Ye Xiao has been through inside the pocket dimension and the Inner World of the Ancient Samsara God.
Of course, she knew all these things only because of the Red Heaven Sword that has been accompanying Ye Xiao for many years now. After recovering his true body and cultivation base, Ye Xiao kept the Red Heaven Sword on the First Floor of the Nine Story Pagoda. Only then did the Red Heaven Sword stop sending the images of what Ye Xiao has been through constantly to its master.
Ye Xiao was completely unaware of a hidden spy staying at his side all this while. If he knew, he wouldn't know whether to laugh or cry.
"Shit! Am I late?"
Zhang Tao muttered, for his heart was agitated after knowing the series of events.
"What do you mean by being late?" The red-haired lady asked curiously.
