However, the fourth-level barrier was incredibly sturdy, actually fending off one wave after another of attacks from the Dao Ancestor and the others!
The Dao Ancestor said in a deep voice, "The energy erupting from this fourth-level barrier feels too familiar; I've thought of a certain someone!"
"Dao Ancestor, who have you thought of?"
Di Hong asked.
"Shen Yu Immortal Emperor."
The Dao Ancestor uttered four words.
"What?! Shen Yu Immortal Emperor?!"
Di Hong's face changed dramatically, "Is it really that guy?!"
"Damn!"
Qing Niu swallowed, saying, "That old guy seems to be the elder brother of Divine Fall Immortal Emperor, and had already stepped into the realm of Immortal Emperor back then, with incredibly formidable strength!
Many strong figures in the Primordial Great Universe have died at his hands!
Even several Immortal Emperor level powerhouses from numerous Great Thousand Worlds have been slayed by him!
If even that old guy is still alive, it's a huge disaster!"
