During the battle, a terrifying aura swept underground, the soil layer was swept away, and Ying Ling and Wu Zhen were getting closer and closer to the underground barrier.

In the end, the Heroic Spirit was defeated first, and with a wave of his claws, he shook Wu Zhen away and jumped out of the pit on the ground.

The black mist expanded, rushing out on its heels.

In the city wall, Du Fei breathed a sigh of relief, if the momentum of the two of them touched the underground barrier, he didn't know how to resist, the combat effectiveness of both sides surpassed him, he could only use Wucheng to defend passively, in that way, he would be equivalent to dealing with the Heroic Spirit and the Black Mist at the same time, with the current state of Wucheng, he couldn't do it at all.

The battle became more and more fierce, and a lot of buildings collapsed, and Du Fei jumped out of the city wall, flew into the air, mobilized a part of his strength, and followed closely.

"Roar!"

An earth-shattering roar erupted from the black mist.

A bony arm poked out, clenched into a fist, and gently smashed out.

At the same time, Du Fei in the sky felt that the dark power from the ground was fighting against Wucheng, and he followed the source of the breath of force, and he "saw" the fist, the black fist, which was very similar to the power of a human soul, but it was impossible for humans to have such an evil and dark soul, and besides, the black fog was obviously a zombie, how could there be a human soul.

Du Fei resisted Wu Cheng's hostility towards the fist and looked at the ground with an expectant gaze.

"Thousand ...... Soul...... Crack! ”

A hoarse whimper floated out of the black mist.

The fist bombarded in the Heroic Soul strong and thick. Strong paws.

Click!

The solid red and black muscles cracked, and the blood rushed wildly.

Ying Ling didn't seem to expect the power of this punch to be so terrifying, and he was smashed unsteadily, and stumbled backwards.

Heavenly, Du Fei caught. Holding the opportunity, the power bombarded down, with his sluggishness, but also with the momentum of Wucheng.

Bang!

The Heroic Spirit's backward body stopped, and was smashed into the ground by the force that fell from the sky, only half a meter away from the barrier.

On the other side, a black mist floated and hurried to it.

Sensing the danger, the Heroic Spirit raised its neck, its clean skull facing the sky, its mouth wide open, and two staggered rows of long, pointed teeth parted.

"Aang!"

"Aang!"

For the first time, the Heroic Spirit let out a unique roar, at first, the voice was very weak, sneering, very unpleasant, and then, as if breaking through some obstacle, the voice suddenly rose high-pitched, and an invisible wave of sound rushed into the sky.

In the sky, Du Fei was hit by the sound, but he didn't feel any pain, but his head was a little dizzy.

Kiss!

Kiss!

With the roar of the Heroic Spirit, the flesh covering the neck changed, the color became lighter, and the thick muscles gradually became lighter, as if they were weaker, but the flesh that had stopped at the neck began to grow again, spreading to the head at lightning speed.

The flesh and blood covered the white skull, layer by layer, as if brushed with layers of blood-red paint, and in the crazy growth, the flesh and blood on the head of the heroic spirit became more and more, and the muscles on the body also quickly thinned, and the strength was greatly reduced.

In order to obtain a complete flesh and blood body, the Heroic Spirit does not hesitate to weaken the strength of its body, which is not known to it whether it is good or bad, but for humans, it is definitely a bad thing, because its breath is getting stronger.

Having a head is considered complete, and the Heroic Spirit paid some price in exchange for a complete body, although the body has become weaker, but with a head, it will obviously be more powerful.

In the hollow eye sockets, two blood-colored eyeballs gradually formed, turning, and very agile.

The change of the Heroic Spirit was very fast, almost instantaneous, and only Du Fei, who controlled the whole city above, could see this change process, and the black fog that was approaching could not all perceive all this.

Before the black mist approached, the fully transformed Heroic Spirit couldn't wait to show off the power of its new self.

This time, the Heroic Spirit roared again, facing straight ahead.

Rise!

The heavy aura was like a giant steel plate stacked on top of each other, carrying an irresistible terrifying force forward.

In the sky, Du Fei, who was only slightly affected, was like being hit by mountains thousands of times, roaring and flying into the distance.

Smack!

Du Fei's back slammed into the barrier in the sky with a crisp sound, and then he disappeared from the sky and appeared in a wall somewhere on the ground.

Just wiped a little corner, and let him fly out so far, it is conceivable that the power of this roar, then, how much impact the zombies will bear in the face of this roar, Du Fei is worried that the zombies will not be able to hold on, and he is even more worried that the city wall will not be able to hold up.

Directly in front of the Heroic Spirit is the black mist, and further on, is the city wall, and the nervous Du Fei is hidden in the wall.

To Du Fei's surprise, the black fog blocked it, but a scene that he didn't expect appeared.

A surging roar crashed into the black fog, and the black fog immediately swelled. Swelled, like a squished hamburger, twisted and deformed, and then cracked, but, after cracking, two clenched fists appeared inside the black mist, and the fists were wrapped in black energy, exuding an evil aura.

When he saw the two black mist-like fists, Du Fei hadn't noticed anything unusual, but after the black mist completely dissipated, he saw the human creature hidden in the black mist, it was not the zombie who fought for them before, but a living person, although half of the entire body had turned into a flowing black mist, but from the remaining half of his face, he could vaguely distinguish the identity of this person, he was the human who broke into the martial city, Wu Zhen.

He's still in Martial City, fighting for humanity!

Du Fei's brain suddenly went blank, how could this be? So, what about the zombie that was in a similar state to Wu Zhen now? They all possess such black mist-like energy, and they are all fighting for humanity, and if they say that the two have nothing to do with each other, they won't believe it if they kill him.

"How could it be you?" The surprise in Du Fei's heart became stronger and stronger, but it was more shocking, whether it was a zombie or Wu Zhen, they were all helping them! Desperately trying to help them!

Wu Zhen's fist collided with the shockwave of the Heroic Spirit's invisible roar, and after the piercing explosion, the Heroic Spirit remained in place, while Wu Zhen was shaken back and tumbled and fell not far in front of the city wall.

Du Fei appeared from within the city wall and walked forward quickly, trying to help Wu Zhen up.

At this moment, probably hearing the footsteps behind him, Wu Zhen, who was lying on the ground, glanced back, and a trace of murderous aura appeared in his dark and cold left eye.

Du Fei was chilled and couldn't help but take a few steps back.

"My goal...... The goal is ...... Be...... Heroic ......"

Wu Zhen got up flexibly, squatted slightly, and jumped up suddenly.

An even thicker black mist spread out from his body, covering his body little by little, Du Fei could no longer see the situation inside, even if he controlled the power of Wucheng and could see all corners of the city, he couldn't see through this black mist.
