Variant biological system

() This green-skinned unknown creature failed to succeed even after three attempts, but the scalp was smashed by Fan Fayin for the last time, and a trace of green juice-like blood flowed out.

The green-skinned unknown creature seemed to be angry. It took a few steps back, and suddenly opened its mouth and let out a sharp howling sound. Then it stood in the corridor, stared at the people inside through the window, with a ferocious and terrifying look on its face.

"What is this unknown creature doing? Why isn't it moving?" A girl next to her was still in shock and couldn't help asking Fan Fayin strangely.

Fan Fayin shook his head, not knowing why.

Xu Qianming pondered for a while, then suddenly understood, his expression changed drastically, and he said, "No, this unknown creature is calling for help—"

As soon as the words were finished, there were several sharp screams outside, and immediately after, the door of the classroom was hit with a loud "boom" and "boom".

This green-skinned unknown creature was so powerful that the door shook immediately when it was blasted, and everyone in the classroom was shocked. If they rushed in, everyone would be Nirvana here.

"Quick, quick, block the door!" Sun Yali screamed, and was the first to rush up.

Soon, everyone rushed forward and blocked the two doors tightly.

In addition to the two who were knocking on the door, everyone saw two more outside the corridor, plus the one with the broken skin earlier, a total of three green-skinned unknown creatures, bombarding the windows together, smashing the glass, trying to get in. Come in.

"One person guards one window!" Fan Fayin yelled, clutching the chair tightly with both hands, as soon as the green-skinned unknown creature got in a little bit, it would hit it hard.

Xu Qianming also held a chair to guard a window, smashed it twice, but found that his hands were faintly numb, and looking at Fan Fayin and another boy, cold sweat broke out on their faces, and everyone couldn't hold on for long.

The two doors were also constantly shaken by the bombardment, and cracks gradually appeared on the top, and the situation became more and more dangerous.

"No, we can't hold on any longer. There are five green-skinned unknown creatures outside. We are all nirvana..." Xu Qianming muttered silently, rushing into a total of more than a dozen green-skinned unknown creatures, and there were five of them. He ran outside their classroom, not knowing whether it was their honor or their fate.

Seeing that the green-skinned unknown creature in front of him had just penetrated half of its head every time, and when he smashed it, the other party shrank back, which was useless. Suddenly, a crazy idea popped up in Xu Qianming's mind, and he took a step back to the left.

The green-skinned unknown creature smashed heavily on the iron window, making it faintly deformed, and tried again and again to get in through one of the iron bars.

This time Xu Qianming didn't hit it again, but leaned to rest as if he was tired.

Soon, a head of the green-skinned unknown creature got completely inside.

"Xu Qianming—" Fan Fayin turned his head to see it by accident, and yelled in horror, "Hurry up, it crawled in."

"It's okay." Xu Qianming took a few breaths. Seeing the green-skinned unknown creature get into half of his body in the blink of an eye, Fan Fayin was so frightened that his hands and feet went limp. If this powerful monster was allowed to get in, they would all be finished.

Breathing in, Fan Fayin turned around to help Xu Qianming smash the green-skinned unknown creature that had just crawled in. Suddenly Xu Qianming grinned and said, "It's time."

He gripped the chair tightly with both hands, and with all his strength, he slammed down on the green-skinned unknown creature that had just climbed a little way in, together with the bars.

With a loud bang, Xu Qianming's hands were numb from the shock, and he vaguely felt that the tiger's mouth might be cracked, but he couldn't care less, Nirvana was still alive, Xu Qianming crazily smashed at the monster like crazy.

Fan Fayin was suddenly dumbfounded, and then suddenly realized.

Previously, the unknown green-skinned creature only reached in a little bit, and they rushed to smash it out of fear. As a result, they lost their strength in vain, and they couldn't do any harm to the unknown green-skinned creature. His body was originally a little smaller than the iron grid, but with this smashing, he was stuck in the iron window grid, unable to move forward or retreat, he could only be stuck there with his hands tied and let them bombard him.

Xu Ganming seemed to be crazy, and kept hitting the green-skinned unknown creature, green juice splashed out, the green-skinned unknown creature let out a horrible howl, and the wooden stick in its hand fell off.

Although it was extremely powerful, its body was also made of flesh and blood. Xu Qianming slammed it wildly with his chair, and soon lost its breath.

"Go to Nirvana, hateful unknown creature—"

Xu Qianming escaped like a collapse, the last chair fell, only heard a "crack", the chair shattered and fell apart, and the head of the green-skinned unknown creature was also shattered.

Then, Xu Ganming saw with his own eyes a gleaming black spar-like thing popping out of the shattered head of the green-skinned unknown creature.

As soon as the thing came out, it flew into Xu Qianming's nearest left palm with a "hoo", and then miraculously merged into the left palm and disappeared.

Seeing all this, Xu Ganming was startled. He couldn't help but step back, and then looked at his left hand, but there was nothing. Could it be that he was dazzled just now?

Looking up, he saw that Fan Fayin had been reminded by him, and followed his example, waiting for the green-skinned unknown creature to squeeze half of its body in before bombarding it.

Unexpectedly, this green-skinned unknown creature let go of the wooden stick in its hand, pulled the iron window with both hands, and smashed against Fan Fayin. With a pull of both hands and a kick of both feet, it rushed into the classroom through the iron window Inside.

At this moment, Xu Qianming realized that it was not that he was smart enough to kill the unknown green-skinned creature with his wisdom just now, but that the unknown green-skinned creature was too unlucky. He went in, but his lower body got stuck and he couldn't move, which made him a big deal.

An unknown green-skinned creature rushed in suddenly, and everyone in the classroom screamed loudly. Several female students huddled together were so frightened that their legs trembled and they lost control of their urine.

Fan Fayin fell back out of fear and fell to the ground.

This green-skinned unknown creature seemed to hate Fan Fayin so much that it didn't even pick up the wooden stick on the ground. It stretched out its claws and grabbed Fan Fayin's face and chest on the ground.

With the terrifying power of this unknown green-skinned creature, this grab can crush Fan Fayin's head, and even disembowel him.

At this time, Xu Qianming had just smashed Nirvana's unknown green-skinned creature. Turning his head and seeing Fan Fayin's danger, he lifted a chair beside him and threw it in the air without thinking twice.

With this shot, Xu Ganming suddenly felt something was wrong with his body.

Just now, he was so tired that he was so exhausted that he almost had no strength to lift a little finger, but he didn't want to throw a chair out with ease at this critical juncture.

But the most astonishing thing was that after the chair was thrown, it made a "hoo" sound in the air. The speed and strength were beyond imagination.

"This..." Xu Qianming turned his head in shock, and then felt that the power he just had came from his left hand, a power that was definitely not what he should have had.

Turning his head, he clearly saw black flesh scales about half the size of a fingernail appear on the back of his left palm.

With a loud sound of "Peng", the chair flew out in the air, hitting the green-skinned unknown creature that had just pounced on Fan Fayin who fell to the ground.

The green juice splashed, the chairs fell apart, and the green-skinned unknown creature screamed and was thrown flying horizontally.

At this moment, Xu Qianming suddenly thought of the small black crystal that popped out of the shattered head of the unknown green-skinned creature when he had nirvana just now, flew into his left palm and disappeared.

Could it be that all this has something to do with that crystal?

Xu Ganming unconsciously let go of his left palm, and the strange force dissipated automatically. The small black scales on the back of his left hand disappeared, and his left palm returned to normal.

All of this seems real and unreal, the only thing that is true and certain is that the green-skinned unknown creature that he just smashed into the air turned over and got up, howling hoarsely, staring at Xu Qianming with a pair of eyes, with deep hatred in it, snatching it away. The wooden stick it had just lost on the ground rushed towards Xu Qianming.

With a chill in his heart, Xu Qianming hurriedly stretched out his left hand again, grabbing the wooden table beside him and lifting it.

The strange force in the left arm reappeared, the wooden table flew horizontally, and the stick of the green-skinned unknown creature hit the wooden table, with a "crack" sound, the wooden table shattered, and fragments splashed out.

Xu Qianming snorted, suddenly felt severe pain in his chest and abdomen, and fell down with a scream.
