Obsidian can easily cut off the claw stab of the first-order mutant animal body. Unexpectedly, Zhang Mu suffered a great loss here. He just couldn't squeeze in. The speed of his sudden increase was forcibly slowed to zero.

Compared with Obsidian's confused and unconvinced, Zhang Mu's heart has blossomed happily.

Unexpectedly, the strength of this spiritual barrier is so high, but it can't attack actively. It's just for defense. However, even this one, Zhang Mu is now satisfied, because he was most worried about the lack of too much spiritual defense. Now his relatively obvious loopholes have become one of his strengths under the wrong circumstances, This is what he never thought of.

Now, not only has the spiritual defense been qualitatively improved, but also the spiritual strength has been tough enough to easily resist the physical attack of second-order alien animals such as obsidian. Moreover, Zhang Mu feels that this ability is not only in defense, but can definitely give a fatal blow to the opponent in close combat.

However, the Obsidian insect was not convinced. It felt that even Zhang Mu's spiritual barrier had not been broken, and it lost the insect in front of him. It whispered to Zhang Mu, "I wasn't ready just now. I bumped it casually. Do it again."

Zhang Mu didn't care. Just now the Obsidian didn't break the defense of his spiritual barrier, so he didn't lose much of his spiritual power. From his point of view, there was only a ripple on the barrier.

He also wants to see where the limit of this spiritual barrier is, but he doesn't know if Obsidian can do it.

After getting Zhang Mu's permission, the Obsidian retreated a large distance again and reached 20 meters away from Zhang Mu.

Zhang Mu narrowed his eyes and looked at the obsidian in the distance. He also began to be in full readiness. He naturally let go of all his mental power and spread it evenly to every part of the whole barrier under the traction of his ability.

Of course, he tried to concentrate his mental strength at one point, but now he is very hard to do. He can't change the formed mental barrier at all, so he had to give up.

It's also that he is too greedy. He has just advanced to the second level. He wants to skillfully use the obtained ability. It's just whimsical. The ability at each stage needs to be slowly mastered and improved in continuous application.

Just as Zhang Mu was thinking, the Obsidian insect moved, its two wings fluctuated up and down, and the dust under its hind legs was slowly rising, and involuntarily gathered around its wings.

Moreover, at the same time, Zhang Mu can clearly detect the changes in the air.

It's the wind!

Obsidian is gathering the power of wind. Yes, it itself is a variant beast of wind attribute. Zhang Mu has not seen it realized at the first level. Now it should be the ability to master after breaking through the second level.

Wind swirls slowly condense around Obsidian's wings, becoming stronger and stronger, and it is still gathering!

Zhang Mu's eyes were frozen. This time it seemed that he had stimulated the obsidian. He didn't know whether his spiritual barrier could carry the full blow of the obsidian. The main reason was that the momentum of the Obsidian was so frightening that the roofs of the surrounding houses were lifted one after another. The high wind that had calmed down was irritable again under the call of the obsidian, It began to wreak havoc near the obsidian, but the Obsidian seemed to be in the center of the eye of the storm, standing still and slowly accumulating strength.

The wind whirled around the Obsidian insect's wings, and no air flow escaped. Zhang Mu looked at this posture, calling all the air flow of a kilometer around to his wings by the Obsidian insect.

I don't know why, Zhang Mu is inexplicably guilty. This time the Obsidian really showed all his skills.

Boom!

Obsidian stopped absorbing wind energy, and its wings could not see the original shape. They were wrapped by layers of air flow and expanded for nearly five meters, forcibly expanding its small wings, which were only one meter long.

It seems that maintaining such power has reached the limit of obsidian. If it is not released, the Obsidian will lose control of the power of the wind, but it still sent a message to Zhang Mu, "If you confiscate it carelessly, you may have a big game. Be careful and withdraw if you can't carry it. If you can't carry it, I don't know how much I can take back at once. This power is a little out of control, because I'm officially used for the first time."

Zhang Mu gave a heavy sound in his heart. If the Obsidian didn't give him pressure, he couldn't judge where the maximum limit of his spiritual barrier was. Now it seems that the power of this test should be enough.

After getting Zhang Mu's permission, the Obsidian moved, and its body seemed to break through the sound speed. Zhang Mu's eyes had not blinked this time, but had come to him with two pairs of remarkable wind wings.

"Coming!"

Zhang Mu just heard the warning sound of obsidian, he felt two heavy blows blow to his head from top to bottom. As soon as the two wind wings were lifted, they cut down on Zhang Mu standing there.

It stopped within one meter above Zhang Mu's head. At the place where the spiritual barrier contacts the wind wing, a large number of energy collisions occur every second.

"Click, click."

At the moment of alignment, the mental barrier appeared a cobweb like crack and was expanding.

"Do you want to stop?" Obsidian asked at this time, "now I can dissipate most of my strength."

Obviously, he saw Zhang Mu's decline, but Zhang Mu now has a hard mouth. He must see where the limit of the spiritual barrier is, so he clenched his teeth and said, "continue, don't stop!"

This is Zhang Mu's order, and obsidian can only listen to it. The wind wing suddenly presses down, and the two erupt strength at the same time. A large amount of air flow escapes where they touch the spiritual barrier and keeps coming out.

The cracks are increasing, and the Obsidian's wind wing changes the attack, constantly hitting the invisible barrier above Zhang Mu's head, alternating the opportunity not to fill Zhang Mu with spiritual force at all.

Finally, the crack of the mental barrier was overlapped to a point, and it was about to break.

Yila, the spiritual barrier completely cracked, a hole opened, and the others were broken.

Zhang Mu was ready to move away from his original position. He suddenly found a very strange phenomenon. Although the cold wind kept pouring in, the attack of obsidian did not fall.

It turned out that while spending time with his spiritual barrier, the wind element energy that Obsidian had just over gathered was also directly worn away.

That is to say, this time, the spiritual barrier constructed by Zhang Mu's spiritual force is equivalent to the wind energy excessively gathered by obsidian.
