The female researcher didn't dare to say much, took one of her potions from the countertop, and didn't know whether it was a semi-finished product or a failed product, so she aimed the needle at the blood vessels of Ye Fei's arm and slowly pierced it......

Seeing the yellow liquid being pushed into his body little by little, Ye Fei's breathing couldn't help but become short, he was completely gambling on his life, no one knew what he would become after the injection.

Is it dead or alive, or is it a mutant human, or a killing machine like a rampaging prisoner? or...... Getting stronger?

Only by becoming stronger than now can it be possible to break through the outer encirclement, otherwise even if you survive, you will be shot and killed indiscriminately.

After the injection was completed, the female researcher took out the syringe and stood there in a daze, and the other researchers also stared at Ye Fei with wide eyes, and some even couldn't help but take a step back.

And Ye Fei could feel something in his body entering from his arm at this moment, and it began to flow to his whole body.

"Go on. Ye Fei clenched his fists.

The female researcher put down the empty syringe in her hand, picked up a syringe again, and slowly pierced the needle into Ye Fei's arm, and then slowly pushed the defective medicine inside into it.

Several of the surrounding researchers began to look at each other, looking at each other with fear, confusion, and shock.

"Go on. ”

The female researcher wiped the cold sweat on her forehead, her breathing was a little trembling, she picked up the third syringe, and when she bent down to inject Ye Fei, Ran Guohao's voice suddenly sounded outside the door, and the nervous female researcher shook her fingers in fright, the syringe fell to the ground and shattered, and the yellow liquid flowed on the ground.

"Ye Fei, you think clearly, this door can't stop us forever, it's not too late for you to turn back now, don't do stupid things again......"

"I'm sorry, I'm sorry......" When the female researcher saw that she had broken the potion, she hurriedly apologized, her whole body was swinging, and her breathing was so frightened that she was intermittent, obviously terrified.

Ye Fei was too lazy to go to Ran Guohao outside the bird, he frowned and glanced at the female researcher, and then glanced at the other man with Sven-looking eyes: "You come." ”

"Ahh......h

He took a potion, came to Ye Fei's side, swallowed his saliva, and carefully pierced the needle into Ye Fei's arm.

The potion began to flow wildly in Ye Fei's body, stimulating every inch of Ye Fei's muscles, but Ye Fei felt that his hands and feet were becoming weaker and weaker, and even his mind began to blur.

"Keep going until I say stop!"

Then, more than a dozen remnant mutation pills on the table were injected into Ye Fei's body one by one, and the more the researchers around them looked at it, the more frightened they became, with their cognition, any medicine here was a terrible liquid that would kill people, but after these pills entered Ye Fei's body, they did not react for a long time, which was simply unbelievable, and they even began to wonder if their research was wrong.

But soon, as Ye Fei suddenly fell to the ground, their hearts also rose to their throats.

After a moment of dead silence, the man with Sven glasses who was still holding a potion was the first to react: "Quick, see if the circuit can be restored!"

"Yes, yes!" everyone came back to their senses and ran towards the power box that was destroyed by Ye Fei.

Soon......

"It's okay, it's just cut off part of the wiring, and if you reconnect it, you should be able to restart the power. ”

"Pull out the knife first. ”

Several people worked together to slowly pull out the horizontal knife with difficulty.

"Since this knife is made of such good steel!" The man with glasses took a look at the horizontal knife and immediately exclaimed: "The custom price of this knife must be expensive." ”

"You don't care if you don't have a knife, come and help with the wiring. That guy doesn't know when he's going to wake up, and even if he dies, he's going to be that kind of monster!" said one of the researchers.

As soon as his voice fell, several people looked at Ye Fei who fell to the ground, their eyes full of palpitations.

Although Ye Fei was now in a motionless coma, it was undoubtedly a nuclear bomb that could explode at any time to them! They couldn't imagine what Ye Fei would look like when he began to wake up, whether it was a mutant corpse or some other kind of killing creature.

Anyway, they all died.

"By the way, let's go and see how Lao Wang is!" said the man with glasses suddenly.

The person next to him also reacted, and walked quickly with him to the man who was kicked by Ye Fei before.

The eyed man squatted down and tested the pulse of Lao Wang's neck: "Not dead!"

"Really!" said the other, with a smile on his face, and stretched out his hand to push the old king, who was sitting on the wall, and immediately drew a painful groan from the latter.

"Several broken ribs. The man with glasses touched Lao Wang's body and exclaimed.

Another man was terrified: "If he wakes up, I'm afraid we'll all die here...... Alas......"

"Sigh, I don't think he looks like he's going to kill us, or we'd have died. The man with glasses said: "I'm afraid that he injected so many mutation drugs, in case of mutation, then we will really die." ”

"Alas, the aliens haven't started attacking yet, so we're going to explain it here. ”

The man with the eyes impatiently patted the other party's thigh with the blade of the knife: "What the hell are you talking about, aren't you reconnecting the circuit over there, as long as the power is restored and the door is opened, a large number of troops outside will naturally protect us." ”

"You can think about it...... I don't know what's going on outside, I haven't moved for so long......"

"Ah!!h

There was an exclamation, which frightened everyone in the room. Everyone saw that it was the female researcher.

"What's the matter, what did you suddenly call, it scared me to death!" someone asked.

The female researcher pointed in horror in the direction where Ye Fei was: "Move...... Moved...... It's moving!"

Hiss~

Everyone's hearts were shocked, and they all gasped in fright by this sentence, and they all looked at the place where Ye Fei fell, only to see Ye Fei lying on the ground, one right hand trembling and shaking.

"Could it be that the mutation has begun?" a cold sweat flowed from the glasses man's head, and he clenched the horizontal knife in his hand.

The person beside him was even more unbearable, and he collapsed directly to the ground, his lips trembling: "It's over, it's over...... We're dead...... Dead ......"

"Hasn't the power been restored yet?

"This ...... It's just a little better, it may be too late, what should I do?"

"It's miserable, he's already starting to mutate!"

In a panic, Ye Fei's two arms moved, unconsciously scratching and shaking on the ground, and then his whole body began to tremble.

Looking at Ye Fei, whose movements were getting bigger and more weird, the researchers present shrank into the corner in shock, and only felt that the farther away from Ye Fei was better.

"uh~~~~"

Suddenly there was a ghostly hiss in the research room, and the researchers who were cowering by the wall were frightened for a while, and their backs were cold.

"What...... What's the sound?"

"It's him...... It's him!" The female researcher whimpered as she pointed at Ye Fei's trembling head.

"I can't wait for the power to be restored, so kill him while he can't move!"

"It's useless, even if he dies, he will still mutate, and we will die the same. If he had woken up and had come to his senses, we might have a better chance of living. ”

"That's impossible, after injecting so many defective potions, it's a miracle not to die, how can he still stay awake, and when he wakes up completely, he will definitely kill us all!"

"If he lives, we will die, if he dies, we will still die, it's over, we can't be saved!"

The crowd let out bursts of wailing, and some even began to cry and cry, shouting that they didn't want to die. These people study mutant monsters every day, and I'm afraid that not many people will know the horror of mutant monsters better than them, but only when they really face such a threat, will they feel how terrible the oppression from the threat of death is.

"Don't make a noise!"

A shout of anger stopped everyone, it was the researcher who had been trying to restore the power supply, he kept operating with his two hands, and his face was covered with beads of sweat: "There is still time, you still don't come to help, will you just cry there and wait for death!"

Only then did everyone react, they had not really reached a dead end, and there was still a glimmer of hope, and more than half of the people ran over with rolling and crawling, raising flashlights and wiping sweat.

"Actually, there is another way. The man with the eyes said suddenly.

"What way?" the crowd looked at him again.

The man with glasses shook the shiny horizontal knife in his hand: "Cut off his head!"

Everyone was stunned for a moment, and then several people excitedly said: "Yes! As long as you don't have a head, you can't move even if you mutate!"

"That's right, that's right! The brain is the dominant part of the whole body, even if the head of a mutant human is broken, it will die! The mutant corpse can't move without a head!"

"Who's going?"

The group of researchers was silent for a while, and finally gradually all looked at the man with glasses holding a horizontal knife in his hand.

"This ......" The man in his eyes was stunned, looked at Ye Fei, who was twitching violently not far away, and then looked at the knife in his hand......

"Okay, I'll ......" The man with glasses swallowed his saliva and walked lightly towards Ye Fei.

The entire research room immediately fell silent, and the heavy breathing declared the tension in everyone's hearts.

At first, the man with glasses walked towards Ye Fei in small steps, but when he got closer, his steps became smaller and smaller, and in the end, he only dared to move a little bit against the ground.

But at this moment, Ye Fei's whole body convulsions suddenly stopped, and a long groan came out of his mouth, like a demon.

The man with the eyes was so frightened that his whole body immediately stiffened, and he didn't dare to move, so he stayed in place and gasped.

"Hurry!"

Not far away, someone was urging.

The man with the eyes gritted his teeth and forcibly suppressed the fear in his heart, stepped to Ye Fei's head, aimed at his neck, and screamed, and slashed down with a whin.

The position of the knife is a little off, and it is in the middle of Ye Fei's head!

However......

It was like slashing on a solid rock, and the knife that the man with glasses was holding almost came off.

"This!" he looked at Ye Fei's intact head in disbelief, almost thinking that he had hallucinated.

The researchers who watched the man's movements in glasses were also stunned for a moment.

With their strength, they can't kill Ye Fei at all!

"How is this possible?" The man with glasses was a little out of control, this was beyond his cognition at all, even if it was the strength of a mutant human, at least a trace would be chopped and then bleed.

Is it harder than a mutant human!?

The man with the eyes gritted his teeth and raised his knife again, aimed at Ye Fei's neck again, and used all his strength to slash down!

However, in the eyes of everyone, the horizontal knife stopped in mid-air, and one end of the blade was firmly grasped by a palm.

Wake up!

The eyed man felt that his heart was about to stop, only to see Ye Fei's face down head slowly turn around, and a pair of bloody red eyes locked on the eye man the moment it was revealed!

"Kill ~~~~~"

A terrifying killing aura enveloped the entire research room, and the air began to freeze!
