Rebirth of the Wilderness

"We can only make do with it for now, and we'll see if there are other options later..."

Looking at these colorful beast souls, Zhao Song could only accept it helplessly. What else could he do? It was good enough to have them...

Although the beast's soul is now extremely complicated, Zhao Song can at least get some inspiration from it...

I believe that as long as I accumulate slowly, I will eventually gain some understanding. If that were the case, Zhao Song could still accept it, but...

"Unfortunately, the number is still too small..."

Zhao Song thought with emotion that if he wanted to slowly study and accumulate, he still needed to have sufficient ferocious beast soul materials for his research...

"This won't work. I guess we have to think of some other solutions..."

Zhao Song has been searching diligently for several years, but the number of ferocious beast souls he has obtained is still in the single digits. If this continues, by the time he slowly accumulates them, the opportunity will be gone...

It's not that he didn't think of using the souls of some innate creatures for research. According to Zhao Song's estimation, the souls of innate creatures must be purer and stronger than those of fierce beasts. The effect would be much stronger than studying fierce beasts, and it would definitely be twice as effective...

But it's not realistic to think about it. From the time he traveled to this primitive world until now, hundreds of thousands of years have passed, and he has not seen many innate creatures. These innate creatures are much rarer than those ferocious beasts...

Zhao Song guessed that perhaps only when most areas between heaven and earth were filled with innate vitality, various innate creatures would gradually increase in number...

However, it is still unknown how long it will take for this innate vitality to evolve, and distant water cannot quench immediate thirst...

As for the innate creatures that appeared now, each of them had a good background, and most of them were not inferior to him in cultivation. Zhao Song wanted to study them, but was that possible...

Let’s not talk about whether he can find it or not. Even if he is lucky enough to find it, can he easily control those innate creatures? It is time-consuming, laborious and dangerous. If he is not careful, he may capsize in the ditch. He will not seek trouble for himself...

Of course, Zhao Song did encounter a weak innate creature before. It was one day a few years before Zhao Song went out to look for souls...

Zhao Song discovered a source of chaos and wanted to try his luck to see if there were any ferocious beasts lurking there. Unexpectedly, his luck was quite good and he discovered a gestating innate creature...

This surprised Zhao Song very much, but at that time he had just started the search, so he was not as impatient as he is now. He would not kill an innate creature who had not yet been born, had a bright future, and had no grudges against him just to speed up his progress in comprehending the soul law. He still had this bottom line...

It can be said that the innate creature was lucky. If he met Zhao Song now, would he let him go? Hehe...it's hard to say...

Zhao Song, who has been in a state of anxiety for a long time, has become a bit demonic now. If he encounters a congenital creature like that again, it is hard to say whether he can still bear it...

"We have to think of other ways..."

Zhao Song made up his mind.

“Although the various myths and legends of the past life may not be true, there are still some references…”

Among all kinds of myths and legends, if we talk about the place with the most souls, it has to be the underworld, which will never be absent in any legend in later generations. There are only ghosts, and they are all different. It is a paradise for studying the laws of the soul...

"Unfortunately...it's still too early"

The last time Zhao Song went up to the starry sky from the top of Buzhou Mountain, he found that the thirty-three heavens and the eighteen layers of the underworld were still in the process of being conceived. Given the size of the heavens and the underworld, it was impossible for them to be conceived so quickly after only tens of thousands of years...

"Besides the underworld, where else could there be a gathering place for wandering souls..."

Zhao Song knew that it was impossible to go to the underworld now. He could only hope to find some clues from the fragmentary legends of later generations and make some references...

What's more, it didn't take much effort for Zhao Song to find a clue, which was the legendary "Sea of ​​Blood".

In some legends of the previous life, Hou Tu, one of the twelve ancestors of the witch clan, accidentally passed by the sea of ​​blood and saw many wandering souls drifting in the sea of ​​blood, and those wandering souls were devouring and killing each other...

Seeing this tragic scene, Hou Tu Zu Wu suddenly felt compassion in her heart, and sacrificed herself to heaven and earth, opened up the underworld, and created the six realms of reincarnation, with immeasurable merits...

However, with Zhao Song's current knowledge and realm, he naturally knew that the underworld was one of the two poles of heaven and earth naturally nurtured by the prehistoric world. It was just that it was still in the process of nurturing and had not yet been born. It was simply formed naturally...

Moreover, the personal strength of Hou Tu, the ancestor of witches, is simply not enough to open up the underworld and create reincarnation. He guessed that it must be the ancient world that used the sacrifice of Hou Tu, the ancestor of witches, to open a certain key and perfect the laws of heaven and earth.

However, Zhao Song doesn’t care about these things now. Regardless of whether the legend is true or not, the "Sea of ​​Blood" does exist, and Zhao Song firmly believes in it.

As long as one's cultivation reaches a certain level, one will be able to vaguely sense the existence of the "Sea of ​​Blood" and vaguely know that the Sea of ​​Blood was transformed from Pangu's navel and is a key link in the operation of heaven and earth.

The "sea of ​​blood" you sense is deep in the earth, and no matter where you are in the wilderness, you can sense that the "sea of ​​blood" is right under your feet...

But sensing is sensing, but entering is difficult. If you know how to enter, then no matter where you are, you can easily reach the "sea of ​​blood" with just a thought...

But if you don’t know the trick to enter, then you can only use the stupid method and slowly shuttle in from the primitive land.

Of course, Zhao Song didn't know how to get in now, so he could only use the stupid method of going through underground...

……

"Why is it still so far..."

Zhao Song was originally good at the Five Elements Escape Technique. With the blessing of the Five Elements Escape Technique, he was able to travel very quickly. You know, the Five Elements Escape Technique is the most suitable magical power for traveling underground. When you cultivate to the realm of mutual generation and mutual restraint of the five elements, you can use the five elements of gold, wood, fire, earth, and water as a boost. Most of the prehistoric land is made up of these elements, so the speed of traveling underground with the Five Elements Escape Technique is faster than flying in the sky...

Moreover, Zhao Song's Five Elements Sky Escape Divine Ability can be said to be unrivaled in the entire prehistoric world, but Zhao Song really didn't expect that the prehistoric earth was so thick and difficult to pass through. If he couldn't feel the target getting closer and closer, Zhao Song didn't know if he could hold on...

After an unknown amount of time, Zhao Song just kept practicing the Five Elements Escape Technique. He felt like his nerves were almost numb, and he encountered a new problem...

Thick earth air filled the entire underground space...

"No wonder only the witches use turbid qi to practice. It is completely incompatible with the nature of mana. The difference is too great..."

At a certain depth, the turbid air in the ground becomes thicker, which blocks the passage, making it more difficult to pass through...

This turbid air was incompatible with his magic power. One was heavy, the other was light, and they conflicted with each other. Now Zhao Song had entered the ocean of turbid air, just like a drop of water suddenly falling into a boiling oil pan, causing Zhao Song to suffer greatly...
