Although the two fought outside the corridor, Yun Ye did not relax at all, because no matter which side won the battle, it would not be beneficial to Yun Ye and the others.

Because, no matter which side wins, they and others will have to bear the attack of the winning side.

In the fierce fight, one of the mutants seemed to have discovered Yun Ye's figure, gave up culling the mutant birds in the corridor, and slammed hard at the wooden door, and let out a roar of unknown meaning in his mouth.

Hearing the roar of the mutant, several mutants around him also gathered around him, slamming into the solid wooden door in front of him.

Where could the solid wooden door withstand the impact of these mutants, and the wooden door suddenly creaked overwhelmingly.

Can't let them rush in.

Without hesitation, the long knife in his hand stabbed out forcefully from the big hole broken by the mutant bird.

Poof, blood splattered, and an angry roar rang out from outside, but it didn't seem to hurt the mutant's vital parts.

After failing once, Yun Ye did not give up, and the long knife kept stabbing from the entrance of the cave.

After dozens of knives, Yun Ye still didn't hear the system's prompt sound, which meant that he hadn't killed even a single mutant after these dozens of knives.

No, it's not the way to go.

The long knife in his hand no longer stabbed, Yun Ye's face was pale, and he was short of breath and leaned against the door while looking around with his eyes, trying to think of some way to break the situation.

After these dozens of knives, he basically used all his strength for each of them, and now he felt that his body was a little weak, and if he continued like this, sooner or later he would not be able to resist these manic mutants because of fatigue.

When he saw something in the room, Yun Ye's eyes lit up, and he immediately yelled, "Chen Lei, come out to help!" ”

After a while, Chen Lei walked out of a small door in a panic, "Ye, Brother Ye, what's the matter?" ”

Yun Ye pointed to a large iron cabinet in the room that was more than two meters high and more than one person thick, and said, "Seeing that cabinet is not, push it down and push it over." ”

"Huh?" Chen Lei's face was bitter, the big iron cabinet looked like it weighed two or three hundred pounds, and it was not easy to push it with his small body, and ...... Chen Lei cast his eyes on the wooden door that was shaking violently behind Yun Ye, seeing the way the wooden door trembled violently, Chen Lei had already guessed what was outside.

"Hurry up, or we'll all die here!" Yun Ye looked at Chen Lei as if he was scared stupidly, and couldn't help but speak anxiously.

"Oh, oh...... Good. Chen Lei nodded hurriedly, and it took a lot of effort to turn the big iron cabinet more than two meters high to the ground, and then his face turned red and slowly pushed the big iron cabinet in the direction of Yun Ye.

"Squeak~~~~~~~!"

After a long and sharp and piercing sound, the big iron cabinet was finally pushed in front of Yun Ye.

"How long will it take to be inside?"

"There's too much clutter, but it's fast, two minutes at most." Chen Lei gasped behind the iron cabinet and replied.

"Do you have any bullets in your gun?"

“…… It's over at the door. ”

Yun Ye was silent, he was still going to use a pistol to kill the mutant, but the two of them had no bullets in their pistols, so they had to give up this idea.

“…… You go to the back to help, I'll guard here! ”

"Okay, Brother Ye be careful."

Chen Lei said and ran inside without looking back, in fact, he didn't want to stay here, he wanted to go to the back to move sundries instead of fighting mutants here.

Yun Ye, who was against the door, took a deep breath, then slammed the latch open, and then rolled himself up to the top of the iron cabinet.

Boom! With the opening of the latch, the double-opening wooden door was suddenly broken open by a force, but then the end of the two doors was blocked by a large iron cabinet, and it was difficult to open for half a minute.

Between the two doors, only a narrow passage was left that barely allowed one person to pass through.

The mutants outside the door saw that the wooden door was opened, and they all squeezed inside, which caused a phenomenon that even one mutant could not pass.

Yun Ye held the long knife in his hand, standing above the iron cabinet, looking at the mutant who was struggling to squeeze in at the entrance, the corners of his mouth outlined a touch of indifference.

This was exactly what he wanted, and he knew that these mutants, although much stronger in all aspects of their bodies, did not have the slightest sanity to speak of, and their first reaction to seeing food was to kill them desperately.

"Roar!"

After seeing Yun Ye standing on the iron cabinet, the mutants outside the door were even more excited than before, and they all rushed towards the gap that only allowed one person to pass through, squeezing and squeezing.

Seeing that a mutant was about to climb up the iron cabinet, Yun Ye's eyes lit up, and the long knife in his hand slashed out diagonally.

Poof, I don't know whether it was intentional or not, when Yun Ye's blade was about to slash the mutant's head, the mutant's head shrank back, and the waving arm just collided with Yun Ye's sharp blade.

Without the slightest surprise, the mutant's arms rose into the air, bringing up large patches of scarlet.

Immediately after the blade reversed, Yun Ye took a small step forward, and the cold light in his hand stabbed out hard, and the mutant could not dodge, and was pierced through the head by the sharp blade.

"Kill a level 2 mutant and gain 5 XP."

The blood-red color in the pupils of the mutant whose head was pierced gradually faded, and the body also collapsed to the ground, trampled to the ground by the mutant who pounced on it from behind.

Without the slightest pause, Yun Ye swung the sharp blade in his hand again, and the body of the second mutant who rushed was pierced, but it did not hurt his vital point.

This serves no purpose other than to make the mutant more manic due to injury.

Yun Ye looked puzzled, he found that after he became weak, his head also deviated, obviously stabbing towards the heart of the mutant, but it ended to be stabbed in the abdomen.

Seeing that the mutant was about to climb up the iron cabinet again, Yun Ye turned into a stabbing slash.

Poof.

A line of blood spurted, and a head was in the air.

"Kill a level 2 mutant and gain 5 XP."

This time there was no misdesignation, and Yun Ye successfully separated the corpse of this mutant.

However, the ensuing scene made Yun Ye frown, only to see that the severed mutant head was actually being fought over by several mutants, and there was a corpse with a broken head beside them.

With his eyes sweeping, Yun Ye was shocked to find that the corpse of the mutant body that had been pierced by his own head had actually disappeared, and the corpse next to those mutants was about to come out.

Soon, several mutants competing for the skull were decided, and one of them, one with ten fingers as sharp as a blade, emerged victorious.

He easily cracked open the mutant skull with his fingerclaws, pulled out a pile of red and white brains, and sent them into his large, scarlet mouth full of sharp teeth.

The behavior of this mutant reminded Yun Ye of a mutant he had encountered before.

Eat your companion's brain body and make yourself stronger!

Yun Ye has encountered such a mutant more than once, and at first he thought that it was a specific mutant that could enhance his strength by devouring the brains of his companions, but now it seems that the truth is not what he guessed.

After eating the brain, the mutant fell to the ground, and its body twitched violently as if it had goat epilepsy.

Gotta stop him!

Yun Ye knew that once he made that mutant stronger, his situation would only become more dangerous.

It's a pity that although Yun Ye has the heart to stop him, he doesn't have the strength to do so.

Because there are still five or six crazy mutants in the gap between the two doors that want to be killed.

It's just that this time Yun Ye didn't dare to kill again, he was afraid that the mutant he was killed would be obtained by that mutant again, which would only speed up the speed at which he became stronger!

Therefore, Yun Ye no longer kills the mutant, and only stabs the mutant when he wants to climb up, and it is all stabbed in an important part, just to prevent the mutant from climbing up.

However, after a few slashes, Yun Ye still had to kill a mutant because he had already climbed onto the iron cabinet and came towards Yun Ye to kill.

The mutant's corpse was unsurprisingly obtained by the previous mutant, who once broke open the head of the dead mutant and sent the brain into his own blood-red mouth.

The mutant who had eaten the brain seemed to be unsatisfied, and without warning, it burst out, stabbing its claws into the heads of its unsuspecting companions.

"Roar!"

The mutant's behavior was tantamount to a war cry, and the mutants who had wanted to break through turned around and lunged at the mutant.

The doorway suddenly became empty, and a few steps away from the doorway was a scene of extremely bloody and brutal fighting.

The mutant who had eaten the brain body was obviously much more powerful than the rest of the mutants, and he did not fall behind in the slightest under the siege of five or six mutants, and even killed one of the mutants who besieged him.

Visiting.

Under the visit, the besieged mutant level immediately appeared in front of Yun Ye's eyes.

"Mutant, level four."

Level 4!

Yun Ye didn't expect that this mutant, which was no different from other mutants, would actually be as high as his own level, and with his current state, he would definitely lose if he fought with him.

Under the turn of his mind, Yun Ye turned down the iron cabinet and closed the wooden door directly with the iron cabinet.

And just when Yun Ye just reached the wooden door, Chen Lei ran out excitedly and said to Yun Ye,

"Brother Ye, the door is open!"

"Let's go!"

Yun Ye was overjoyed, he was worried about how to deal with that mutant, but he didn't expect the back door to be opened at this time.

Coming to the back door, Yun Ye asked a few people, "How is it, what's going on outside?" ”

"It seems safe at the moment."

"Okay, stay safe."

Yun Ye nodded at a few people, and took the lead in front with a knife.

"Crunch."

The iron gate was opened, revealing the silent street outside, and Yun Ye, who was in the lead, waved to a few people behind him after observing the surroundings.

When everyone saw this, they rushed out.

Listening to the roar of fighting coming from the street in front of him, Yun Ye motioned to a few people to go in the opposite direction, and leave here first.

Shout!

A gust of wind blew, and Yun Ye felt a sense of crisis, and hurriedly roared.

"Get out of the way!"

Bite!

The long knives collided, sparks flew everywhere, and a strong force struck, and Yun Ye was directly shocked back a few steps.

"Mutant, level three."

Damn it!

Yun Ye's face was gloomy, he didn't expect to encounter a third-level mutant at this time.

With the long knife in hand, Yun Ye took the lead in rushing towards the mutant.

And that mutant was not to be outdone, as if the phalanges of a blade were slashing at the rushing Yun Ye.

"Dingding......

From time to time, there were a few sounds of metal clashing, and Yun Ye slashed open one of the mutant's arms, while his left hand gripped the mutant's other arm.

"Kill him!"

Cold Frost Moon had been waiting behind Yun Ye for a long time, and the moment she heard Yun Ye's call, her slender and weak body suddenly shot out, and the blue ice spear in her hand stabbed straight into the mutant's head.

"That's ...... Stranger! Two soldiers in camouflage uniforms in an abandoned high-rise building glanced at each other, and the look of horror in their eyes was self-evident.

"Such people must be recruited!" One of the soldiers whispered.

The other soldier nodded thoughtfully, "The man with the knife is also strong. ”

"I'll report to the commissar ......"
