According to the description, it clearly refers to the masked woman.
Ethan Smith immediately looked down.
He saw that there was a densely packed line of text below, all of which contained rumors about the masked woman.
According to the book's record, the masked woman suddenly appeared five thousand years ago, killing countless people.
"Five thousand years ago... that must be her first successful reincarnation." Ethan Smith thought to himself.
Because Ethan had met the masked woman in the Immortal Slaying Sect, and at that time, she had already wiped out the entire sect a million years ago.
Ethan continued reading and scanned the entire section.
After reading, he found out the masked woman indeed killed countless individuals five thousand years ago!
There were sect masters who merely looked at her twice and were consequently annihilated along with their entire sect, not a single disciple spared.
Even worse, some faced death for merely gossiping about her behind her back.
