Hearing Lu Yu's question, Ao Guang was stunned for a moment.
Immediately, Ao Guang seemed to have thought of something and immediately said: "I found this cave before because the spiritual energy here is much richer than outside. If I practice again, I can save a lot of hard work."
Lu Yu nodded: "The aura here is indeed a bit unusual."
"Um?"
Ao Guang had an idea and quickly asked: "Is there something special about this place? When I first found this place, I also searched for it, but I only found a few medicinal plants."
Lu Yu closed his eyes, and the power of his soul immediately swept around him.
At this moment, Lu Yu did not hide his strength.
Ao Guang stood next to Lu Yu and felt the most vivid feeling. For a moment, he felt as if his whole body was being seen through by Lu Yu. There was no secret at all around Lu Yu.
"How far has his soul grown?"
Ao Guang roared in his heart, and his loyalty to Lu Yu became a little bit more.
Under the scanning of the soul power over and over again, the surrounding scenery has been roughly revealed in front of Lu Yu.
By the time he reached the human-immortal realm, Lu Yu could almost exert some of the power of his soul.
Every plant and tree around here, even a speck of dust in the sand, could not escape Lu Yu's eyes.
"Sure enough, there is something hidden underground!" Lu Yu's eyes flashed, and he suddenly used the Earth Escape Technique to drill directly into the ground.
Ao Guang saw this and followed him.
Both of them are great masters of supernatural powers. They are monks who have reached the third step of enlightenment. Flying to the sky and escaping from the earth is just a matter of thought.
Passing through layers of mountains, the land below becomes harder and harder, and many places are paved with hard rocks.
"The God of Hades slashes with rage!"
With a thought in Lu Yu's mind, his whole body simulated the sword energy of the Severing Sword, cutting open the rocks in front of him, and his whole body was like a sword piercing into the depths of the earth.
"Sir, this place is already three thousand meters deep underground, and there is nothing there." Ao Guang was a little confused.
When we got here, we were close to the core of the star, and even the surrounding temperature began to rise.
Moreover, there is a creature called the earth demon in the underground.
These earth demons are born to only grow underground and cannot see sunlight. They can only survive by using the poor resources underground.
It is precisely because of this that earth demons are often cruel by nature and need to kill a large number of their own kind in order to survive.
At this time, countless earth demons gathered around Lu Yu and Ao Guang.
Judging from the appearance, the appearance of the earth demons is very ferocious. Their eyes and noses have degenerated, and their faces look like ghosts without facial features.
This group of earth demons came together in groups, with tens of thousands of them rushing towards Lu Yu.
"You are a bunch of scum, get out of here!"
Ao Guang directly exuded the pressure of his Dragon King, and the pressure of the Earth Fairy Realm instantly shocked all the surrounding Earth Demons.
However, this shock is only temporary.
As one man and one dragon continued to sink, more and more earth demons gathered around them, and even some powerful earth demons began to approach here.
"Sir, do we want to go back?" Ao Guang also had a layer of cold sweat on his forehead.
He could easily kill one of them, but these demons were endless, and it seemed as if he couldn't kill them all.
If he were killed here, he would probably be devoured into a withered skeleton by the earth demon in the blink of an eye.
"You are here to protect me. I don't have time to pay attention to these earth demons now." Lu Yu said lightly.
