Roar! Roar! Roar!
Calamity Beasts surged in from every direction like a tide, shaking the surrounding void with thunderous rumbles as they lunged at Lu Ren and Mu Hanxue.
Lu Ren and Mu Hanxue had no choice but to unleash their full strength again. They cast Immortal Path Techniques one after another and wiped out every Calamity Beast.
Yet the moment they finished, calamity aura surged around them like a tide and gathered into more Calamity Beasts. Each radiated a terrifying presence as it charged at the two men.
"This Xuanming Immortal Ancestor actually set up a formation like this to test people!"
Lu Ren's expression grew grave.
Killing two waves of Calamity Beasts had cost them a great deal of Calamity Power. An ordinary cultivator would have run dry long ago.
"As far as I know, the Xuanming Immortal Ancestor wasn't skilled with formations!"
Mu Hanxue frowned slightly.
After studying it for a moment, Immortal-Smiting Iron started in surprise. "This Life and Death Contract Formation seems to have been inscribed over the original!"
"Inscribed over it? What do you mean?"
Lu Ren was startled.
"It means the original formation was broken, and an entirely new one was inscribed in its place!" Immortal-Smiting Iron said.
"Why would someone inscribe a new formation?"
Lu Ren asked.
Mu Hanxue's brows drew tight as he guessed, "Could someone have beaten us to the Xuanming Cave Mansion? Was this Life and Death Contract Formation laid by someone else?"
Roar! Roar! Roar!
Calamity Beasts charged from every direction again, fiercer and more overwhelming than either of the first two waves.
Lu Ren and Mu Hanxue could no longer dispatch them as easily as before. The stronger beasts had reached Fifth Tribulation Transcendence and Six Tribulation Transcendence.
Killing many of them was no longer a simple
