The Obsidian insect, which was not Zhang Mu's fantasy, took advantage of agility to dodge. There was no trend to curb the speed. In just five seconds, all the mutant animals it came into contact with were either cut in half by steel wings or directly torn into pieces.

The occasional fish that escaped the net was easily sucked into a corpse by the blood vine lotus within 50 meters of Zhang Mu, but it seemed a little impatient because it could only watch the Obsidian kill.

But its body grows in Zhang Mu's arm and can't extend at all. It can only watch Obsidian kill heartily, and then enjoy different flavors of mutant animals and their cores.

When Zhang Mu saw this, he put his heart down. It seems that he still underestimated the lethality of obsidian after advanced. It's not just that it's powerful just now.

At this time, Zhang Mu had quietly eaten ten soul crystals, and an inexplicable palpitation suddenly came out of his heart.

Finally coming? The opportunity to advance to the second level!

His soul, which had been tempered for a long time, felt numb, but now the opportunity for advancement finally came. He suddenly summoned up his spirit and felt every change in his body.

In a sudden moment, he felt that all the cells of his body were calling for energy, which was the feeling of hunger. He wanted to absorb energy from the inside out and greedily stripped it from the air.

Zhang Mu knows that this is the natural response when the perception of ability has reached the bottleneck and the body needs to advance. A person's awakening ability is like water, and his body is a container. When the water is saturated, if the container does not increase its volume, it will burst and explode.

This is why the evolutionists who advance through awakening ability are so much stronger than the normal evolutionists, because the volume required at this moment of advancement is much larger than the normal ones.

Therefore, advanced is a very dangerous thing, but Zhang Mu is confident enough. The energy in the air is naturally scarce, which is far from what is needed from first-order to second-order.

However, in his current era merchant ring, there are tens of thousands of first-order yuan crystals!

Under normal circumstances, a first-order evolutor needs only about 1000 first-order crystals to succeed in the case of direct advancement. When he evolves his own equal order to the second order through the ability of awakening, he needs at least 3000 crystals, and there is no upper limit.

Because everyone's ability requires different meta crystal energy, it's not necessarily that the more they need, the stronger their ability is, but it's always better to prepare for a rainy day.

He put the remaining soul crystals on the ground into the era merchant ring. This time, he should not be able to use them. He can give them to Yuanrui after his advanced work is completed. Even if the number is not enough, Yuanrui can understand a new additional ability, but it is enough to make up for her lack of spirit in the nightmare bug this time.

Moreover, Zhang Mu felt that these soul crystals could at least enhance Yuanjing's spiritual defense to the strength of ignoring the dreams made by those nightmare insects just now.

After collecting the soul crystal, Zhang Mu counted the number of 10000 yuan crystals directly from the era merchant ring this time, and immersed himself in the yuan crystal ocean. Even the position of xuetenglian was crowded by the yuan crystal ocean.

At the moment when Zhang Mu summoned Yuanjing, his body sensed the source of energy and madly obtained energy from Yuanjing like a whale swallowing water.

The layer of Yuanjing closest to Zhang Mu's body suddenly turned into powder, and then new Yuanjing was pasted on Zhang Mu involuntarily, and then absorbed.

Each of his meridians is saturated and full of the most initial energy, which is digested by his hungry body. Now his spiritual power has no floating, and Zhang Mu is waiting for his body to be saturated.

In the twinkling of an eye, the 3000 yuan crystals needed for evolutionary ability were absorbed by Zhang Mu, and he could clearly perceive that these were far from enough. The yuan crystal ocean around him had shrunk at a speed visible to the naked eye.

The whole body is swollen and full of strength, although it doesn't belong to him yet.

With the passage of time, Zhang Mu felt that he had almost reached his limit. He opened his eyes and looked at the surrounding environment. He found that his side had become white powder, leaving only about 1000 intact yuan crystals lying quietly in the white powder.

He actually used nearly 9000 yuan crystals in the process of first-order to second-order advancement, which makes Zhang Mu feel a little sad, but it also proves the domineering place of using the ability of spiritual awakening to advance in some way.

Now is the time to impact the last moment. Zhang Mu closed his eyes again.

Now the mental power accumulated in his brain and the energy accumulated in his body have reached the bottleneck he can accommodate, so he began to mobilize these overflowing energy with difficulty.

Click, his brain seemed to crack. This pain is beyond the average person's ability to withstand.

Even if Zhang Mu has been tempered for a long time, he really burst his brain. It doesn't feel like an ordinary explosion, but Zhang Mu knows that this is the last step of his breakthrough and must resist it.

His expression that had not moved at all just now slowly began to appear a trace of ferocity, but he could only silently bite the back teeth and not relax. If he relaxed now, he would fall short and be doomed.

Fortunately, Zhang Mu got too much mental training some time ago, first zero, then nightmare bug, and finally the erosion of more than a dozen soul crystallization energy. He can carry this breakthrough.

After carrying the most violent wave, he relaxed, felt his spiritual power slowly integrate into the widened brain domain, felt that his meridians were affected, wantonly absorbed the energy just stored, and became strong and tough. He breathed a long breath in his heart. It was really not easy.

Now he can feel the pain of obsidian in the advanced stage. He really doesn't want to do it again.

When everything in his body settled down, Zhang Mu suddenly stood up. He looked at his hands. Although there was no change, he could sense the explosive force hidden in them.

However, the functional changes of the body are not the most important. Zhang Mu immediately wants to know what ability he has grasped in the spiritual department in this advanced stage?

He began to mobilize the huge mental power stored in his brain and put it out to the outside world.

It's it?
