At this moment, Lu Yu's eyes seemed to be shining with a trace of thought.
The soul behind him also began to flicker. In an instant, thousands of thoughts flashed through him, constantly calculating the position around him.
"Jie Jie, this human race is probably too scared to speak out!"
An ancestor of the earth demon couldn't help laughing when he saw Lu Yu's appearance.
Lu Yu's body, tempered by two ancient body-refining techniques, is extremely attractive to these monsters.
If they could devour Lu Yu, their cultivation would at least make another qualitative leap.
Finally, one of the Old Demon Ancestors flew toward Lu Yu.
Compared with Ao Guang, who was more difficult to deal with, it was easy to deal with Lu Yu.
Seeing the Earth Demon Ancestor approaching, Lu Yu shouted coldly and suddenly let out a loud shout.
"Those who are facing a battle must march forward in formation!"
The nine-character mantra turned into nine large golden characters and emerged in the void. Each character had an extremely mysterious power attached to it, sweeping away the surrounding darkness.
Boom!
All the demonic energy around them was frightened by these nine characters, and some weak earth demons were directly shaken to pieces.
This was the spell used by the Demon King back then, and it has extremely powerful restraint against such underground evil spirits.
"Ah! What kind of magic is this!"
The Earth Demon Ancestor who originally flew towards Lu Yu suddenly screamed, and bursts of black energy began to emit from his whole body.
As these air currents continued to drain away, the giant body of the old demon ancestor seemed to have lost its strength and began to gradually become smaller.
"No! No! Why is my power dissipating little by little!" Old Demon Ancestor screamed, turned around and prepared to escape.
Lu Yu looked at him coldly and shouted: "You are an early Earth Immortal, you should keep this cultivation level."
Almost instantly, Lu Yu came to the Old Demon Ancestor's side in a few flashes.
It would still be difficult for Lu Yu to deal with mid-stage Earth Immortals like Xu He. However, these early stage Earth Immortals have just gathered the five elements and have not consolidated their cultivation, so they are just a little stronger than ordinary human immortals.
They are no match for Lu Yu at all.
Lu Yu instantly moved to the side of the Earth Demon Ancestor, stretched out his hand and pressed it directly on his forehead.
The power of Taotie Tuntian suddenly exploded, and the old demon ancestor suddenly felt that all the power in his body was being stripped away quickly.
"Quick! Save me!"
Seeing this, the other three Old Demon Ancestors did not dare to fight with Ao Guang and came to rescue one after another.
"Well done. Since the three of you are here to die, I'll take them all!"
Lu Yu looked at the three demons coldly, shouted loudly, and the nine-character mantra struck these demons like five thunders.
In just the blink of an eye, all the four demon ancestors let out pitiful screams.
"No, this guy is a tough guy, we made a mistake!"
"This guy's technique completely restrains us. We can't fight back at all!"
The four demons complained endlessly and sent messages to Lu Yu to beg for mercy.
"No more fighting! We are willing to surrender to you!" the four demons shouted loudly.
Lu Yu, however, still turned a deaf ear and said coldly: "A group of demons, who knows what you are thinking about. If I subdue you, you will probably look for opportunities to retaliate against me all the time!"
While speaking, Lu Yu directly used his supreme magic power to refine all four demon heads.
