Ye Xiao merely noted this in his heart without mentioning it in the Immortal Realm.
That year, three thousand immortal sects had ambushed his cheap father.
Logically speaking, with the sects behaving like this, it was impossible for the immortal sect not to know anything about it.
Even if they had all remained within the Immortal Realm and never appeared outside, there should have been communication between the various sects over the years.
Otherwise, where would the Heaven and Earth Rankings of the Tianya Haige come from?
However, even with the flow of information, those cultivators had no recollection of the surname "Ye."
Thus, Ye Xiao could conclude that someone must have tampered with those cultivators, or even the entire cultivators' world, making everyone forget the surname "Ye."
Now, among the people Ye Xiao knew, the most likely candidates capable of doing this were Mo Wentian, or the old man who was still clutching his wine gourd, pouring liquor into his mouth.
