In the barren mountain forest, the breath on the Heroic Spirit's body became more and more manic, the flesh covering the leg bones stabbed, and there were continuous blood bubbles rising and exploding, and the bright red blood spread to the white bones on the Heroic Spirit's body, and where it passed, the red and tender flesh grew out, quickly becoming tough, and then wrapped in a layer of slightly black crusty cortex.

The flesh and blood on the Heroic Spirit's body gradually increased, and its aura became thicker, as if it had become another kind of life, no Heroic Spirit had ever been able to have flesh and blood, but today there was an exception, the bones alone could reach the god level, once it had the outer layer of tough muscles, what would it become? Du Fei originally thought that the barrier of Wucheng was strong enough to resist the impact of the Heroic Spirit, but he never imagined that the Heroic Spirit had become stronger.

Du Fei has no intention of fighting the Heroic Spirit, he has no chance of winning, and the only thing he can rely on is the barrier in the sky, so he must wait for the evolution of the Heroic Spirit to end.

In his worried gaze, there was a new situation in the evolution of the Heroic Spirit, the flesh covering the neck of the Heroic Spirit suddenly stopped, and it could not spread to the head, the white skull and the dense flesh below the neck formed a great contrast, and the most important part of the Heroic Spirit's head could not evolve, which was a good thing.

The Heroic Spirit swung its claws and smashed the rocks and dwarf trees around it, and it habitually opened its mouth to roar, but it couldn't roar.

Du Fei looked at the Heroic Spirit who was bumping into the Heroic Spirit like crazy on the ground, and fell into thought, it was obvious that the Heroic Spirit had not evolved completely, and there were still some very important things missing, thinking about the problems here, maybe he could find a way to deal with the Heroic Spirit.

When the Heroic Spirit appeared, it slaughtered the xenomorphs, and what important information might be hidden in it, what was it?

The brain of the evolutionary is very strong, and the god-level evolutionary is even more so, Du Fei recalled, and the tiny details everywhere were clearly reflected in his mind, and the scene changed rapidly, and suddenly stopped.

"This is it!"

Du Fei saw a scene that he hadn't noticed before.

The Heroic Spirit is attracted by the blood of the xenomorph, after rushing out of the ground, the Heroic Spirit can't wait to kill the xenomorph, the death of the xenomorph makes the bones on its body harder and more perfect, when the bone reaches the limit, it begins to grow flesh and blood, all of this must be driven by the flesh and blood energy of the xenomorph, when the last xenomorph dies, the changes on its body suddenly accelerate, and the speed of flesh and blood coverage increases wildly, that is to say, all the xenos in Wucheng are the prey of the Heroic Spirit, and they are all necessary for its evolution.

If the xenomorphs do not die, it is impossible for the Heroic Spirits to fully evolve.

In the end, Du Fei came to his own conclusions.

"No, the wild bear is not the last xeno!"

Du Fei recalled the zombie that left, it was also a different species, but it seemed a little wrong, the Heroic Spirit did not show a very long desire for the zombie, otherwise, it should leave now and go after the zombie, instead of going crazy and crashing on the ground.

"Wrong! Wrong! And a xenomorph! ”

Du Fei suddenly realized that there was a powerful xenomorph in Wucheng, to be precise, it could only be regarded as a half-xenomorph, it was an old monk who was half human and half zombie.

Relying on the strength of Wu Cheng, Du Fei instantly enveloped Wu Cheng and quickly looked for the location of the old monk.

Wucheng is wrapped in an energy layer, the bottom is a hemispherical shape, the top is also, and in the middle is a circle of erected city walls, in this range, Du Fei can be said to know everything, any corner can be seen by him, but, after searching twice, Du Fei was horrified to find that he could not find the location of the old monk, and when he saw the crowd that arrived in Nancheng, he did not find the zombies from the crowd.

Not only these two, but also a human disappeared from his perception, even, he never felt the breath of that person, that person was Wu Zhen who once arrogantly broke into Wucheng and escaped after killing someone, until now, this person has not appeared again, but since it is a human being, it is very likely that he escaped from Nancheng by taking advantage of the chaos, and before the hole in the wall was repaired, this person had many opportunities to escape.

Putting aside the human affairs for the time being, Du Fei is worried about the zombies, will the evolution of the heroic spirit be lacking the old monk and the zombie, then, the zombie is dangerous, the zombie is all broken, and the combat effectiveness is almost nothing, how can it resist the current heroic spirit?

After the heroic spirit almost destroyed the mountains and forests, he suddenly raised his head, and his empty eyes didn't know whether he was looking at Du Fei or the sky.

It seems that the Heroic Spirit can't find the location of the zombies and the old monk either, so it has changed its target, and it has to deal with this piece of heaven!

Du Fei calmed down, mobilized his energy with all his strength, increased the strength of the energy layer of this piece of sky to the maximum, and the time had come to test this piece of sky.

The Heroic Spirit lowered its massive skull, its strong, powerful legs slightly bent, and the muscles attached to it arched and taut like steel bars.

Boom!

Instead of jumping into the sky, the Heroic Spirit began to run.

Du Fei hurriedly removed the energy layer that had accumulated to two meters in the sky and kept up with the Heroic Spirit.

It seems that the Heroic Spirit also knows that now is not the time to strike.

Du Fei's heart gradually panicked, it takes time to enhance the energy layer in the sky, and it can only enhance a small area, the total energy of Wucheng is fixed, if this piece is enhanced, the energy layer in other places will become thinner, and the terrible thing is that the Heroic Spirit will not impact the place he has prepared, it is very smart, and will only choose a relatively fragile area.

Yingling went all the way to the west, running at a speed comparable to Du Fei in the sky, even faster than Du Fei, and it didn't pick the road at all, no matter what was in front of it, lowered its head, rampaged, the collapsed building let out a roar that resounded through the sky, and a long and straight smoke dragon appeared in the center of Wucheng.

What the hell does it want to deal with Wucheng?

The more Du Fei looked at it, the more he felt that it was not good, the Heroic Spirit seemed to have given up on dealing with the sky, so, what could it deal with?

Walls!

Du Fei suddenly came to his senses, and immediately used his ability to launch slowly, slowing down the speed of the heroic spirits running wildly below.

Sluggishness covered the Heroic Spirit, Du Fei immediately felt a huge resistance, and the ability played a role, but it could only play a pitiful little, and the speed of the Heroic Spirit decreased, but it was not obvious.

Du Fei consumed thirty percent of the energy in his body, and finally reduced the speed of the Heroic Spirit to a slower level than himself, and then he went crazy.

Snort!

The resistance of the air was like a sharp long knife, leaving blood holes on Du Fei's body, and the bones were visible deeply.

Anyway, he doesn't need to fight with the Heroic Spirit, as long as he guarantees that he can use the power of the Martial City to block the Heroic Spirit, thinking of this, Du Fei can no longer take care of his body, his speed increases again, and the blood on his body is getting more and more, and finally, the western city wall has arrived.

Rumble!

Du Fei rushed into the wall and merged with the wall.

Bang bang bang!

Buildings exploded in the distance, and Heroic Spirits burst out of the smoke.
