"Since that day it rained, the whole world has changed, the evolution of zombies has accelerated, many survivors who have been drenched in the rain have mutated, and the base city has become a mess, if it weren't for the army to clean up in time, I'm afraid the base city would be gone. Pen? Interesting? Pavilion wWw. ｂiquge。 info" Liu Qiang said with a sad face.

"The most terrifying thing is the winged bird, this newly emerged mutant beast, the size is huge, it can fly, the defense line on the periphery of the base city is useless, and it will come to make trouble in three days, and those people outside are all poor people who have been ruined by the winged bird and killed their relatives."

In the house, Liu Qiang and Niu Heng talked in detail about what happened in the past few days when Zhang Yifeng was away, and Zhang Yifeng also counted it in his heart, all in all, the current Cloud City Base City is not peaceful, and the source of the chaos is the rain before he left the wasteland world.

"The R virus has transformed the world, rain, snow, frost and rain, any kind of meteorological change, will accelerate the evolution of mutants."

Zhang Yifeng couldn't help but think of the words of the nursery rhyme, he had some disdainful thoughts, but slowly became heavy, he felt that his thoughts were a little simple, the wasteland world was over, and he couldn't be alone.

First of all, he will lose the source of wealth, and secondly, the wasteland world exists for an uncertain time, and the dimensional gate has a cooldown, if it happens that one day, the cooldown time is not over, and the cloud city base city is attacked by zombies, will he still have the life to return to the real world?

"There are no eggs under the nest, it seems that I should really strengthen my strength, otherwise I don't know how to die." Zhang Yifeng felt a strong crisis.

Liu Qiang and Niu Heng didn't stay long before leaving, because Zhang Yifeng was there, they decided to go out of the city together to hunt mutants, swallow crystal nuclei to improve their strength, they are the indigenous inhabitants of the wasteland world, and the tragic scene these days has made them have to desperately enhance their strength, otherwise, they may really die in the hands of mutants.

Ma Sichun didn't leave, but looked at Zhang Yifeng quietly, her bright eyes flashed with an indescribable divine light.

Zhang Yifeng has the illusion that this violent Lori seems to have undergone some unknown changes.

"Sichun, can you have a chat with you?" Zhang Yifeng said with a smile.

Ma Sichun tilted his little head, glanced at Zhang Yifeng strangely, and then nodded slightly.

"Sichun, you sit down a little bit."

Zhang Yifeng stretched out his hand and pulled Ma Sichun.

Ma Sichun's petite body stiffened slightly, his face was full of confusion, but he still didn't refuse, got up and walked to Zhang Yifeng's side, and sat down next to him.

Looking at Ma Sichun, who is exquisite-looking, cute and cute, Zhang Yifeng's eyes are very complicated, if he had been in the past, he would have treated her with a normal mentality, but since he met the nursery rhyme, when he heard about Ma Sichun's incredible origin, Zhang Yifeng's heart was a little messy.

"Mina, test Ma Sichun's physical attributes......"

Rubbing his palms against Xiao Lori's double ponytails, Zhang Yifeng squinted his eyes and instructed Smart Mina.

In just a moment, the upper e3 on the wrist vibrated slightly, prompting Zhang Yifeng to complete the detection, this is the power of artificial intelligence, knowing how to be improvised, reasonable, knowing that he can't say it, he uses this way to remind Zhang Yifeng.

"Sichun, go out and play with Xiaohui."

Ma Sichun was stunned, with some reluctance on his face.

"Sichun, do you know nursery rhymes?"

Sudden questions, asked inadvertently, will definitely have a surprising effect, even if it is Ma Sichun, hearing this name, his eyes are also slightly stunned, although it is very short, but it is enough.

Zhang Yifeng knew that Ma Sichun did know nursery rhymes.

"Who are you?"

This is something that Zhang Yifeng has always wanted to know in his heart.

"Uncle, I won't hurt you, and I won't allow anyone to hurt you." The cute baby voice, like electricity, hit Zhang Yifeng's heart, and he looked up in surprise, as if this was the first time that Ma Sichun had said so much.

Her expression was very serious, and there was an unquestionable resoluteness in her delicate countenance.

Hearing her words, Zhang Yifeng's heart warmed, and he said with a smile: "Let's go out and play." ”

"Hmm!"

Ma Sichun is gone, but Zhang Yifeng's heart is turbulent.

"Why am I so sentimental?" Zhang Yifeng didn't understand, his mood was very complicated, and he suddenly remembered the picture in his mind, from the gathering place of Xunyi County to the base city of Yuncheng, Ma Sichun accompanied him all the way, and said unabashedly that if it were not for her, Zhang Yifeng might have died in the wasteland world.

If Ma Si was malicious, with her perverted strength, killing him would be as simple as pinching an ant to death.

"Forget it, I don't want to think so much, Sichun has something to do with nursery rhymes, and the origin is very mysterious, I can't find any clues, after all, it's because I'm too weak to be qualified to contact these at all." Zhang Yifeng thought secretly.

"Uncle Yi Feng, come out and see the big bird."

At this moment, Niu Xiaohui's exclamation suddenly came from outside the door.

"Big Bird?" Zhang Yifeng's eyes were puzzled, and then his face changed wildly, carrying an alloy war knife, he rushed out of the house, stood beside Niu Xiaohui, and looked intently.

Sure enough, in the distant sky, a dark cloud suddenly floated, and it was sweeping towards the base city of Cloud City at an extremely fast speed.

"Sichun, take Xiaohui back." Zhang Yifeng shouted loudly.

As soon as his words fell, a terrible alarm suddenly sounded in the base city of Cloud City, and the survivors in the slum area rioted, hiding in all directions with frightened faces.

The huge black clouds overwhelmed the city, casting a large black shadow of death, sharp birdsong, piercing through the golden cracked stones, and the black shadow Daodao, flying by.

"Ahh

The screams came, like a signal of battle, and dense winged birds descended from the sky, constantly slaughtering the helpless survivors.

In front of Zhang Yifeng, a winged bird also landed, this is a big guy about 6 meters long and about 1.5 meters high, bare, like a red-crowned crane that has lost its hair, with a long beak and powerful wings.

"First class winged bird

Basic strength: 400kg

Exclusive Abilities: Impale, Slash"

"It's so fierce, there are two exclusive abilities!" Zhang Yifeng was taken aback, and his gaze became extremely solemn.

The winged bird in front of him let out a high-pitched chirp, its huge body, pacing back and forth, and then burst out, its wings were closed, its feet were close to its abdomen, like a sharp arrow, towards Zhang Yifeng****.

"This is the piercing ability?" Zhang Yifeng's eyes showed a different color, "I see, the piercing ability of the winged bird is to gather the strength of the whole body on the beak, in order to enhance the lethality, the pursuit of the ultimate penetration, the basic strength of 400kg, plus the speed kinetic energy, I am afraid that it can easily penetrate the steel plate, it is really powerful." ”

"However, the speed of the first-level mutant beast is still too slow."

A silver-white match, burst out in absolute stillness, and the killing machine was hidden in silence, accompanied by a burst of blood light, the huge body of the winged bird, falling to the ground, its body, split in two by the sharp alloy war knife, dead can no longer die.

The alloy war knife can even cut through the scale armor of the golden beast, and it is simply not a problem for a winged bird.

"C-class weapons, it's really terrifying!"

Zhang Yifeng can't remember how many times this is the first time he has been amazed.

Several birdsong in a row came, Zhang Yifeng killed a winged bird, which had already attracted the attention of other winged birds, and the big guy with wings up to 6 meters long spread his wings soared gorgeously in the sky, his eyes were sharp, and he swooped towards Zhang Yifeng.

This time, the winged birds didn't use the piercing ability, and their wings spread out, like two heavenly knives, sweeping in, which was the winged bird's second ability, Slash.

The thin bone wings are incomparably sharp, very hard, and if ordinary humans can't dodge, they will be easily cut in half, which is very terrifying.

"Come on, I want to see if your wings are hard or my sword is hard." Zhang Yifeng sneered all over his face, held the knife in both hands, and slashed towards the winged bird.

With a bang, the metal and iron resonated, the alloy war knife seemed to have slashed on the steel, and the huge shock force came, Zhang Yifeng's mouth was numb, and the alloy war knife in his hand almost came out of his hand. However, the edge of the alloy war knife was not so easy to be blocked, and after a short period of stagnation, with a snort, the alloy war knife directly cut off the wings of this winged bird.

The winged bird, unable to grasp its balance, crashed headfirst into the concrete building, spilling patches of blood.

"Die."

The winged bird was just about to struggle to stand up, when a cold light suddenly appeared, and it was empowered from its head, and the winged bird fell to the ground.

"The second-level winged bird is much stronger than the first-class winged bird." Zhang Yifeng dug out the crystal nucleus of the winged bird, and sighed again and again, if he didn't have an alloy war knife in his hand, I'm afraid he wouldn't even be able to break through the defense of the winged bird, these hairless guys, their bodies are harder than stones.

Killed two winged birds in a row, Zhang Yifeng was in high spirits, he actually brandished an alloy war knife, took the initiative to kill other winged birds, and after a dragon fight, Zhang Yifeng harvested 10 first-class gray crystals, six or seven second-level white crystals, and when it was about to be appropriate to chase the poor man, the people from the Public Security Bureau and the army came.

"It's a pity!"

Seeing this, Zhang Yifeng quietly ran away, he didn't want to be too high-profile, however, although no one saw him, the miserable corpse of the winged bird on the ground still attracted the attention of others.

They're the Secret Service!

Three men in black suits, with machine guns in their hands, walked over slowly, looking at the corpse of the winged bird on the ground, their pupils constricted.

"Such a powerful guy, he actually cut the winged bird in half with a single sword, this kind of strength is probably comparable to the captain."

"Damn, it's really a master in the people, silently, there is another strong man in Cloud City Base City."

"Do you want to tell the captain that this kind of strong man should be pulled into our special service team and contribute to mankind."

"I'll talk about this later, first pack up the things in the sky, and die, you smash them."

Machine guns, anti-aircraft guns, dense bullets, shells, intertwined a network of fire in the sky, countless winged birds exploded, flesh and blood flying, with the continuous output of the army's powerful firepower, the arrogant winged birds in the sky paid a heavy price and fled in embarrassment.

Although the winged bird was repulsed, the Yuncheng base city also suffered heavy losses, countless survivors' houses were destroyed, hundreds of people were killed and wounded, this is only a day's casualties, if the winged bird comes every day, the cloud city base city will not be able to carry it for long.
