It turned out that some rare, high-grade and precious materials in the world often contained large amounts of vital energy.
If those with a lower cultivation base took them carelessly, they could be heavily damaged since they couldn't take in such large amounts of vital energy. The energy that couldn't be absorbed might explode in their bodies and kill them.
Now, Austin was only at the fifth level of Energy Gathering Realm.
It was hard for him to absorb so much vital energy that was equivalent to two Energy-boosting Elixirs.
Fortunately, the torrent of vital energy ran slowly but steadily in him, and no longer flowed away in all sides when he practiced with the Purple Yang Formula accordingly.
With the guidance of the Purple Yang Formula, the vital energy was slowly absorbed, and Austin closed his eyes.
Four hours later, Austin woke up, his eyes bright.
He felt the strength in his body and he knew that he had reached the sixth level of Energy Gathering Realm.
The earth spirit fruit was quite effective, as he only needed one to reach the sixth level of Energy Gathering Realm.
He was even a little surprised at the speed of his improvement during that time.
Back then, he was only at the second level of Energy Gathering Realm--then the third, fourth, fifth, and now he was at the sixth level.
It took him only less than a month to break through four levels in a row.
If people had heard of Austin's cultivation speed, no one would ever believe it.
The people who could reach this speed of improvement were more than geniuses, as it was considered an incredible miracle.
It was already rare for some of these world geniuses to break through two or three levels in a year.
This case of breaking through four levels in a month was completely unheard-of in the Prime Martial World.
However, Austin had previously reached the ninth level of Energy Gathering Realm.
It wasn't a breakthrough, but rather the recovery of his strength. That was why Austin could make it happen.
He had stayed in the cave for almost two days, and wondered i
even seventh level lived there.
There were even remnant species from the ancient times that lived in the innermost heart of the mountain. They were so powerful that they possessed strengths beyond people's imagination.
Now, the great battle that was currently going on was in the innermost part of the Great Desolation Mountain.
The Beast Mountain, which was the junction of the Great Desolation Mountain and the human habitation, was a triangular terrain that protruded from the edge of the Great Desolation Mountain.
"It seems that the legends are real. The demons and beasts in the depths of the Great Desolation Mountain are really horrible," Austin muttered.
These great beasts were so powerful that he couldn't help but be scared and also in awe of them.
He suddenly felt how small he was when he witnessed a battle that shook heaven and earth for the first time.
A man like him was really small and insignificant in such a huge battle!
For the first time, Austin felt the desire to become stronger. His aspiration for power had never been this intense.
However, he realized that he still had a long way to go in the pursuit of martial arts and he was still far away from achieving his goals.
His eyes looked at the fierce battle in the distant horizon. Austin's face flushed, and he clenched his fists as he felt both dread and excitement run through him.
