With the sound of breaking the air in his ears, Chen Qingfeng's upper body leaned forward slightly, dodging a knife swung by the mutant corpse brother.

"The air is so loud and you want to sneak up on me? Can you learn from me, sneak attacks don't make a sound. Chen Qingfeng glanced at the mutant corpse brother who was lying on the ground struggling to support his body with another bone knife, and said in a slightly mocking tone.

The mutant corpse brother wanted to withdraw his arm, but Chen Qingfeng stubbornly grabbed the part of his wrist that connected to the bone knife.

"It turns out that your knife has a joint with your forearm."

Chen Qingfeng took a closer look, and the wrist of this mutant corpse brother resembled a human bone connection, but it was covered by the highly compressed muscles and skin of its body.

Such a structure is very fragile, and it will break as long as the interface is hit hard, but the highly compressed muscles and skin of the mutant corpse brother are intact to weaken this weakness.

But meeting someone who is stronger than it, or stronger than it in one or its own way, can be a very good weakness.

Call! Seeing that Chen Qingfeng was dead, the mutant corpse brother slashed over and wanted to split Chen Qingfeng in half.

The speed of the bone knife was fast, but Chen Qingfeng made a faster block.

I saw Chen Qingfeng clasp the mutant corpse brother's other bone knife and block it at his side, wanting to use the mutant corpse brother's bone knife to defeat its bone knife.

ping！

Like the sound of two sharp weapons slashing at each other, two gaps the size of rice grains appeared in the originally sharp bone knife.

"It's a pity."

It was only a little distance away that he could use the bone knife swung by the mutant corpse brother to cut off the bone knife in his other hand, Chen Qingfeng secretly regretted that he had to contribute himself.

Grabbing the two hands of the mutant corpse brother with both hands, he pulled it back hard, and the mutant corpse brother fell in the direction of Chen Qingfeng with a tall body.

Chen Qingfeng was on tiptoe, rushed out and kicked the mutant corpse brother's head that was about to hit the ground.

Boom! Shot!

The mutant corpse brother instantly reversed direction and fell backwards, and if it weren't for the highly compressed muscles that protected its entire body, this kick would have been enough to kick its head out.

Chen Qingfeng landed next to the helicopter wreckage with a backflip, just now he saw a mountain knife in it, and the two kitchen knives he brought were contributed to the corpse brother on the way here.

I had to find a random steel pipe on the road, but the steel pipe was not used, and it was bent after smashing the corpse brother's head.

Chen Qingfeng took out a mountain-opening knife that was arm-length and had a pitch-black blade, weighed it, and felt acceptable.

"Death to the beasts!"

Chen Qingfeng turned around with the mountain opener in his hand and rushed towards the mutant corpse brother who was struggling to get up.

A big stride jumped up suddenly, and slashed down while the mutant corpse brother had just come back to his senses and didn't react.

The mutant corpse brother had to lie on the ground in a panic and prop up his upper body to make a blocking move.

ping！

The long knife slashed through the bone knife, and a piercing sound sounded, only to see a white mark appear on the blade of the knife!

"It's worthy of buying a knife given away by KW74, it's easy to use, 999 for a knife." Chen Qingfeng tightened the handle of the knife, let alone the mutant corpse brother, he was a little uncomfortable, sure enough, the physics teacher did not deceive me, the force was mutual, unless I could kill it with one knife.

"Abominable humans." The mutant corpse brother was uncomfortable by this knife, and although he blocked it, the force was strong enough to withstand it.

"You weren't human before." Chen Qingfeng said with a smile, lifted the big knife and rushed forward again.

This time, he didn't recklessly face it, but took advantage of the mutant corpse brother's mobility to recover from a place that it couldn't take care of.

Chen Qingfeng rolled forward to dodge the bone knife swung by the mutant corpse brother, rolled behind the mutant corpse brother, and stabbed it at the back of the head while taking advantage of this gap.

Poof! The blade sliced through the skin, leaving a thin streak of blood, from the back of the head to the tail of the spine, from which a small amount of black blood flowed.

"Roar!" The mutant corpse brother turned his head and glared at Chen Qingfeng with a pair of scarlet eyes, but all it saw was the ever-expanding blade!

Burst!

The cold blade sliced through the mutant brother's face, slicing through two of its eyeballs in one fell slash.

"What are you calling a dog? Why are you yelling so loudly? Chen Qingfeng kicked the mutant corpse brother and retreated.

Because of the pain caused by the slashing of his eyes, the mutant corpse brother was now waving like crazy, and Chen Qingfeng didn't dare to stay by its side in this situation, in case he was slashed with a knife, it was not a joke.

Chen Qingfeng saw the opportunity, and when the mutant corpse brother swung his knife, he rushed forward with a big stride, and slashed at the junction between the bone knife and its wrist.

Click, the bone knife snapped.

Chen Qingfeng turned around and slashed out the big mouth that opened at the mutant corpse brother, directly shaved off its entire chin, and with a twist of the knife, it was straight into the mutant corpse brother's brain at its jaw, and the tip of the knife broke its head and pierced its brain.

The mutant corpse brother took advantage of Chen Qingfeng's knife to pierce his brain, and used the last trace of strength to fly it, fortunately, it was the hand that broke the bone knife, otherwise Chen Qingfeng's internal organs were all scattered all over the ground now.

The whole process took only ten seconds, Chen Qingfeng jumped up from the ground with a carp, looking at the mutant corpse brother whose body was still twitching, the black blood flowed all over the ground, and the mountain knife was also wet, Chen Qingfeng had no intention of taking out this knife, anyway.

After a long while, the mutant corpse brother did not twitch, Chen Qingfeng observed for a while, it seemed that he should be completely dead, and then carefully walked around from a position a few meters away from its corpse to the wreckage of the plane.

As soon as he pushed open an iron sheet, four slightly damaged black wooden boxes came into view.

Three of the wooden boxes had KW74 handwriting on them, and Chen Qingfeng couldn't wait to open one of the wooden boxes, only to see that his whole face collapsed.

Inside the wooden box were two potions, one golden and one blue, but both potions were broken, and the liquid inside flowed out and mixed together.

"Grass!" Chen Qingfeng threw this wooden box aside, and hurriedly opened another wooden box, and sure enough, it was broken again.

The helicopter fell on the roof of the building, and the violent impact caused the potions inside the wooden box to be broken.

Chen Qingfeng opened the last wooden box containing KW74, hoping that the potion in it was okay.

When I opened the wooden box, I saw that one of the potions inside was broken, it was the turquoise potion used to ease it, and the golden potion used for strengthening it was fortunately not broken.

Chen Qingfeng put away the KW74 strengthening pill and looked at the other black box, he didn't know what was inside, could it be that it was a mountain knife? It's possible.

Chen Qingfeng opened it and saw that there was a square crystal with countless mirrors, and inside it was a golden liquid that also emitted fluorescence.

"How is this thing so similar to KW74? This packaging is so high-end, is it KW84? Chen Qingfeng picked it up and observed curiously, this thing looked the same as KW74, and the packaging was a little taller.

"What is this?" Chen Qingfeng saw a blank piece of paper underneath, which seemed to be an explanation.

Chen Qingfeng browsed it carefully, his eyes gradually burning hot, because he knew what this thing was.
