When Zhang Mu pinched this smooth spherical object, he didn't know what it was, but his intuition told him that what he had in his hand was definitely a treasure of unimaginable value.

This kind of pleasure was unprecedented. It seemed as if all the cells in his body were trembling with joy. At the moment of touching, it was as if an electric current was transmitted through his fingers.

It was as if there was a voice in my heart saying, "Get it, now, immediately, right away!"

If he didn’t know that nightmare worms were first-order mutant beasts, no matter how powerful their spiritual direction was, there should be no possibility of souls existing after death. Zhang Mu even thought that those nightmare worms that could bewitch people were still alive.

That was a possibility. For Zhang Mu now, this thing was indeed something he desired very much.

When Zhang Mu tremblingly took the small ball out from the layers of fat of the nightmare worm, he finally knew what it was.

It was soft and elastic, a deep blue, crystal clear and beautiful, dotted with stars, just like the vast sea of ​​stars that Zhang Mu had seen at No. 37. It was like the most noble work of art in nature, forming a sharp contrast with the fat and ugly body of the nightmare worm that gave birth to it.

The most important thing is that the fragrance it exudes naturally becomes stronger the closer it gets to Zhang Mu.

It is not only an enjoyment to the sense of smell, but also an enjoyment to the soul.

It's the crystallization of the soul!

Logically speaking, only mutant beasts above level three can generate this kind of soul crystal, and even among the third-level spiritual mutant beasts, this kind of soul crystal is extremely rare. Zhang Mu had seen this thing at the trade fair held by the Epoch Agents. Not only him, but everyone present at the time was deeply attracted to it. Everyone's eyes were filled with greed, but they were afraid of the power of the top few Epoch Agents who founded the trade fair, so they barely let reason overcome desire.

This soul crystal has an extremely incredible benefit, which is that it enhances the soul's defense capabilities. It is also said that when accumulated to a certain amount, it will undergo a qualitative change and add an awakening ability.

Moreover, this awakening ability is an extremely domineering spiritual evolution ability.

That was why everyone was flocking to it, and it caused a nationwide sensation at the time. However, this thing was only taken out for public trading after the strongest people had already saturated themselves and then used it as a bargaining chip.

However, even the spiritual crystals that were considered useless by the top experts were sold at sky-high prices after their functions were introduced at the trade fair. Zhang Mu, who had come to the trade fair to broaden his horizons, could only watch with envy.

However, how could this valuable spiritual crystal appear in the body of a nightmare worm that only looks like a first-level one?

This is also what Zhang Mu found strange. Logically speaking, the existence of this kind of spiritual crystal requires a large amount of resources and energy to fill it, and only the third level can provide such a large amount of resources.

Zhang Mu was puzzled, but he felt that he could no longer control his arms and put the spiritual crystal into his mouth.

There shouldn't be any problem. After the spiritual crystal was successfully auctioned, the buyer took it directly. It should look exactly the same, with no difference.

In order to confirm its safety, Zhang Mu placed the newly acquired spiritual crystal in front of his eyes and examined it carefully. He restrained his desire, examined it carefully, and tried hard to recall the magnified projection of the soul crystal when it was exhibited.

After comparing the spiritual crystal in front of him with the one in his memory, Zhang Mu actually discovered the only difference between the two, which was that the one in his hand was lighter in color.

This seems to explain why a first-level nightmare worm can breed spiritual crystals that other spiritual mutant beasts can only cultivate at the third level, but they are still a little short of the right level.

But even so, it is extremely astonishing.

Zhang Mu vaguely guessed how this nightmare worm obtained energy, which was to keep killing and absorbing the soul power of humans and mutant beasts, all of which was used to cultivate this spiritual crystal, so that their own evolution was slowed down. Therefore, among the first-level mutant beasts, their physical strength is at the bottom. It turns out that this is how the power was irrigated into it.

After some inspection, Zhang Mu finally confirmed that this was the weakened version of the energy crystal he had seen that year. He immediately put it into his mouth without hesitation.

It was swallowed when it touched the ground.

This soul crystal melted in the mouth, like a stream of clear water moistening Zhang Mu's throat, then entering his body, and finally slowly dissolving completely in his stomach and merging into his limbs and bones.

Zhang Mu now did not feel any discomfort even in the cold wind. The power of the soul crystal traveled through his body and gathered at his tailbone.

After gathering all the strength, this ball of energy kept climbing up along Zhang Mu's spine. Zhang Mu enjoyed the tingling and numb feeling very much.

Soon, the energy extended along the nerves in Zhang Mu's brain to the spine and finally reached the depths of Zhang Mu's soul.

The moment it reached his brain, this icy coldness made Zhang Mu wake up with a start. His brain seemed to have expanded a lot, and the most obvious thing was that his mental strength was greatly stabilized. He could clearly compare that if he was restrained by the nightmare bugs again, he would not be suppressed for such a long time.

It is indeed something that a nightmare insect has cultivated with all its essence!

Zhang Mu let out a long sigh. This refreshing feeling was so stimulating. Now he felt that the control over his body had reached a new level.

Therefore, spiritual evolvers generally have unique advantages in combat.

However, after a while, Zhang Mu's expression became strange.

Because the fragrance in the air did not dissipate at all, it was so strong that Zhang Mu's expression instantly became extremely wonderful.

He turned his head to look at the dozens of nightmare bug corpses lying on the ground, and suddenly an idea that even he felt was extremely crazy popped up in his mind.

I just randomly selected the corpse of a nightmare bug, not deliberately choosing it.

Is it possible that all nightmare bugs on earth contain such a soul crystal?

Zhang Mu didn't even think twice and pounced directly towards the nightmare bug corpses on the ground, as if their greasy corpses were the cutest things.

His heart was screaming.

Here I come!
