In the current situation, it may really be necessary to wait for Liu Madlong and them to come over, and then gather everyone's strength to kill the powerful mutant zombie in front of him.

In terms of comprehensive strength, Chen Fei's strength and speed are slightly higher than this second-level mutant zombie, but in terms of endurance and defensive ability, Chen Fei is much inferior.

Because zombies don't feel scared, they can directly meet Chen Fei without dodging when they attack, but Chen Fei is only flesh and blood, and he may be able to exchange injuries for injuries when he fights with other evolutionaries, but there is no point in fighting zombies.

Some advantages in strength and speed are not enough for Chen Fei to break the deadlock in front of him, if he uses the essence of his whole body, Chen Fei will be able to improve his body's abilities by another two or three percent in a short period of time, but even so, in Chen Fei's opinion, it is still not enough to kill this mutant zombie who does not know the exhaustion of exhaustion and physical strength.

What made Chen Fei even more speechless was that he found that as the battle time lengthened, the routines of the mutant zombies in front of him became more and more powerful, and they were evolving from passive defense and counterattack to active attack little by little.

The corners of Chen Fei's mouth twitched, and his face was speechless.

Feelings, he is now playing the role of a whetstone! Little by little, he is stimulating all the strength of the mutated zombies in front of him, and creating the strength of the enemy with his own hands!

Could it be that he just gave up? Waiting for Liu Crazy Dragon and them to come to support?

This thought appeared from the bottom of Chen Fei's heart again, and a voice in his heart kept dissuading him, telling him that it was impossible to defeat this second-level mutant zombie, and once his physical strength went downhill, then he would even fall into a life-threatening situation!

And just when Chen Fei lost his consciousness for a short time, the attack of that mutant zombie was already in front of him!

Chen Fei cut his cheek on the right arm of the mutant zombie turned into a long knife before he could dodge, leaving a wound with a length of four or five centimeters, if it weren't for the extreme reaction of his body when the survival instinct was in danger, Chen Fei would even be directly cut off by the second knife that followed.

Chen Fei retreated quickly with his feet on the ground, touched his cut cheek with his palm, and saw the blood in his palm Chen Fei's face became gloomy.

Nima!

Too much deception!!

Although Lao Tzu eats by strength, but when it is time to fight for face, you have to fight for face, and as a result, you are so jealous that Lao Tzu is more handsome than you, so you have to shave Lao Tzu's face!!

Lao Tzu has to stab you into a hornet's nest today!

Chen Fei roared angrily in his heart, and the retreat he had just had was gone at this moment.....

This opportunity is really important to Chen Fei, rare metal materials mean a lot to him, and after missing this moment, he can only go to those industrial metal material warehouses to find them.

Thinking of this, Chen Fei's expression became more and more fierce, and when he looked at this mutant zombie again, Chen Fei only felt that it was a small boss guarding the bottom of the pass, as long as it was killed, it would be able to explode the equipment.

Made! Fight!

Chen Fei's blood surged with his anger, and the power in his body began to be concentrated by Chen Fei's invocation, there were more than twenty evolution potions on his body, even if his state of full burst strength could only last for a moment, but he could recover his strength by injecting evolution elixirs.

In short, Chen Fei will not give up until the last moment!

As long as he can enter the rare metal material warehouse before the others, even if it is only ten seconds longer, it will be enough for him to collect a lot of rare metal materials.

In the dimly lit warehouse, the figures of Chen Fei and the mutant zombies moved quickly, and many times the attacks were instantaneous.

Because of Chen Fei's attack speed increased again, the body of the mutant zombie began to appear, and the wound left by the spear would flow dark brown viscous blood inside, emitting a foul smell.

And Chen Fei himself was left with seven or eight fine wounds because of the attack of the mutant zombies, and blood oozed out of the wounds, but fortunately, Chen Fei's current recovery ability has surpassed that of most ordinary people, and the bleeding can be quickly stopped without deliberately doing anything.

When Chen Fei and the mutant zombie separated again, this time the mutant zombie did not attack immediately, but suddenly made a forward movement.

At the moment when the tips of the two long knives stabbed on the ground, the legs of the mutant zombie kicked violently like springs, and its body flew low like a swallow, flying low close to the ground, and the target of the attack was Chen Fei's legs.

"Damn, Nima, you are so ruthless, you want to cut off Lao Tzu's legs directly!"

Chen Fei's expression was angry, he didn't dodge left and right, but jumped up in place, and stabbed the spear in his hand down in mid-air.

The legs of the mutant zombie suddenly kicked to the ground, and the body was close to the spear shaft of the spear and rushed towards Chen Fei in mid-air, and the arms that turned into long knives slashed fiercely at Chen Fei's waist.

At the moment of crisis, Chen Fei controlled his body and made a maximum twisting action in the air, which was able to dodge the attack of the mutant zombies.

Looking at the torn clothes around his waist, Chen Fei's palpitations calmed down little by little, and he knew in his heart that his reaction might only need to be a few tenths of a second slower than a second, and he would really be cut into two pieces and turned into a corpse.

After such a fierce battle lasted for another three minutes, Chen Fei could clearly feel that his physical strength was beginning to decline, and he could no longer maintain his peak state.

In fact, with Chen Fei's physical strength, maintaining a full combat state can last for more than ten minutes, but in order to kill this mutant zombie as soon as possible, Chen Fei can only stimulate some potential, and exert one hundred and three percent of his strength to the limit, such a price is naturally a rapid consumption of physical strength and spirit.

And through the battle, Chen Fei has gradually adapted to the fighting style of this mutant zombie, since the beginning of the battle, whether it is offensive or defensive, the mutant zombie has relied on a pair of long knife arms.

This means that as long as Chen Fei can stab a spear that it can't dissolve, he will be able to kill it!

As soon as his mind moved, an evolution potion appeared in Chen Fei's hand, and after the decisive injection, Chen Fei did not have any respite, and continued to fight with the mutant zombies, while accelerating the recovery of physical strength with the help of the evolution potion, while looking for that fatal flaw.

After the injection of the evolution potion, the familiar feeling of ice and fire in the body reappeared, this time the two extreme feelings of cold and heat were intertwined, and it seemed that Chen Fei's body was directly regarded as the battlefield of their battle.

Chen Fei not only had to grit his teeth and endure the pain, but also had to deal with the attacks launched by the mutant zombies.

After more than ten seconds, Chen Fei discovered the abnormality, and as the effect of the evolution elixir took effect, although it was a little painful, his physical strength was rapidly recovering.

It only took a few tens of seconds to recover to the peak state of strength, and after his physical strength was fully recovered, Chen Fei found that there was a pure energy in his body that was scurrying around, as if it was about to break through his body.

How so!!

Chen Fei was shocked in his heart, and the feeling that his body was swollen and painful as it seemed to break him became more and more intense, but his face gradually changed from a trace of inexplicable panic to joy!

Chen Fei could clearly sense the state of his body, and he had sensed that he was just one evolution potion away from an evolution level breakthrough, or an opportunity.

And now it is obviously this opportunity, when the most critical moment of the battle comes, this kind of general feeling is a sign that he is going to break through the barrier of a first-level evolutionary, as long as he endures the past, the cells in his body will further evolve, and he Chen Fei will become a second-level evolutionary!

Although Chen Fei didn't have an intuitive guess as to how much his strength would be able to increase after the breakthrough of the evolution level, even if that dominant bloodline didn't have a substantial attack ability, his strength would definitely increase somewhat!

And as long as the strength increases, the tide of battle is likely to turn around!

So at this moment, Chen Fei is completely enduring the pain and fighting with the mutant zombies in anticipation.

Here it comes!!!

Chen Fei's face, which had become red because of his hard work, suddenly returned to normal, and a majestic momentum spread outward with Chen Fei as the center!

After the mutant zombie felt this terrifying momentum, his body seemed to be restrained, unable to move, but it was a pity that this was a good opportunity to kill him, but Chen Fei closed his eyes and immersed himself in the feeling that his body had become stronger.

"Finally...... Breakthrough! ”
