Biochemical Left 4 Survival

The whole city was quickly powered on, and there was a crackling sound, and one area after another was lit up one after another. In one breath, the whole city was instantly bright as day.All darkness is invisible.

"Oh my god, what is that?" A person looked at the top of his head in horror.

I saw a dark shadow flying in the sky not far away from the original diamond glass cover, like a fast-moving black cloud, and it reached the top of the entire B city in a blink of an eye.

It was getting closer, and finally someone saw it clearly, "It's a bird, it's a zombie bird!"

With a cry, everyone's hearts tightened instantly, and they jumped to their throats.

There was some commotion for a while, some people were whispering to each other, and there were some exclamations in the voices in twos and threes, but generally the situation was still under control.

As expected of a trained person, even those old, weak, sick and disabled who are not worthy of force, still calmed down.It is much better than the performance when the epidemic broke out at the beginning.

The military organized the game in an orderly manner.Fortunately, they had long anticipated the phenomenon of zombie birds returning to their nests, and had made preparations early on.

Don't look at City B's head is only covered with layers of transparent glass cover, which looks clear but is also fragile. In fact, this diamond glass cover can withstand a thousand pounds of force, and it is coated with layers of special paint. Make it more solid and able to conduct a strong current.

Tens of thousands of birds flew over the sky and covered the sky, with blood-red eyes, bald hair, and rotten fur exposed. They slammed into City B ferociously and frantically, with sharp teeth and sharp claws slightly bent, attacking the glass cover desperately .

More hair fell off, but fluttered and didn't know how to be discouraged.

Soon, the glass cover was stained with the blood of zombie birds, black and black, winding down one by one.

When I first saw so many birds crashing down, it was a lie for people to say that they were not nervous.Under the glass cover, the faces of the people in City B who watched the flock of birds turned pale instantly. When they saw that the attacks of those birds were not effective because of the huge number, they unconsciously breathed a sigh of relief and looked at the glass cover. His eyes were a little eager, he clenched his fists, insisted, must persist.

"Power on!" In a building, there are sophisticated instruments everywhere, and on the screen are enlarged and impacted birds. When you look through the screen, there is a feeling that the screen is about to break out. The body was flattened against it, fierce and ferocious.The meandering bloodstains also bloomed on the screen...

But this bloody scene did not frighten the monitors. They carefully observed the relevant data to make sure that the glass was not damaged. They held their hands and looked at the screen motionless, while giving the order to turn on the current.

"Jumping clown!?" Is it really only deterring human beings by numbers?Jiang Cen thought, this bird has never shown anything special, just where they pass, there are no living people, and there are so many bones left, is it really because of the number of locusts? !

"Dr. Jiang, there is something strange here." A staff member who was sitting on the inspection suddenly said, "A group of zombies is approaching."

"Oh!" Dr. Jiang looked away from the zombie bird.

"Oh?!" The voice raised, "I have already entered the area!" I moved the mouse a few times forward, showing the zombie team in the distance in an all-round way.

"This lineup is really big, how can we not give them a surprise."

Press a red button, gunpowder smoke billows up on the screen, and occasionally some broken arms fly out. Although I didn't hear the sound with my own ears, but seeing the thick smoke billowing non-stop, I know the heroic scene.

Like everyone else, Fan Lewen and the two who were preparing to stand by suddenly felt a vibration under their feet.

"What's the matter?" Dong Guoshun quickly stood firm. At first he thought that the shock would be over, but after a short pause, a new round of shock came again, and some furniture in the house began to shake happily. , making a rattling sound, and some dust fell on the wall.

"Couldn't be in time for the earthquake." Dong Guoshun's face turned dark, that would be too unlucky.

"It's okay, it's because a large area of ​​bombs was triggered in front, and it's affected here, it's just aftershocks." After the ground stabilized, Fan Lewen said.

Some explosions could be heard vaguely.

After the electricity was turned on, the birds close to the glass surface were scorched by electricity. Although they could only see flapping wings, the glass cover blocked the sharp voice of the zombie bird. All the wailing was like watching a pantomime. The zombie birds instantly fell like black charcoal.

"Oh!" Everyone in City B cheered, excited and even hugged the people beside them, regardless of whether they knew each other or not. At this time, Dong Guoshun saw such human emotions for the first time after entering City B. In the past, everyone was indifferent like a puppet, doing their own work step by step.This smile eliminated the barrier a lot at once.

Sure enough, happiness is contagious.

The group of zombies in the distance was blown up, and the lost birds in the sky were also suppressed. Jiang Cen was a little satisfied, and everyone in City B was very satisfied. Although the number of lost birds did not seem to be small at all, it was still so dark. However, it is not a matter of time to find a way to deal with them and eliminate them.

"The situation is under control, and we can't help much. Let's go back to wash and sleep, and get up for training early in the morning." A more optimistic person said to the people around him, and some people agreed.The entire city was built brick by brick by them, and they should be the ones who have the most confidence in the city.

Some people left, and Fan Lewen and the others were still watching in the open space, feeling that it would not be so simple as the end.

"Doctor, it's too bad, those zombies haven't been wiped out." The staff member guarding the screen suddenly said, with some panic in the incredible voice.

Jiang Cen froze for a moment, stepped forward quickly, and pushed down with both hands. At this time, the billowing gunpowder smoke had dissipated a little, but he still couldn't see the picture clearly.

This is?Jiang Cen quickly manipulated the mouse, staring at the screen with eyes wide open, not moving for a moment, there are so many zombies, how is this possible.The chain of ammunition only killed about half of the zombies.

Among them, the number of giant zombies is even more astonishing. The gray muscles are tangled and blackened by soot, and they form a circle to protect other weak mutant zombies. Countless zombies stood up and looked in the direction of City B in the distance.

The camera faithfully captured this scene, and many zombies seemed to be looking at everyone coldly through the screen.

"Bo, doctor, what should we do now." Bai Zhanding's staff's voice trembled, and his feet were still trembling.It's crazy, it's a monster, that's several tons of ammunition, is it really necessary to use a nuclear bomb? !

"What are you shaking, let's get angry." Jiang Cen felt agitated for a while. He thought it was a sure thing, but suddenly found out that it was all for naught, which was simply the biggest mockery of him.

However, he calmed down quickly, and quickly revealed his inappropriate mood, and this was just the beginning.

"Report the situation up and move on to the next plan."

The military quickly issued an order, and the alarm sounded again.

Countless people with supernatural powers quickly left the city wearing protective clothing, Fang Li and Zhao Yu were among them.

Seeing Fan Lewen and the two not far away, he was a little surprised and a little relieved, "Did you come to see us off?"

"Come back and invite you to drink." Fan Lewen patted Fang Li and said, then stuffed them with pistols and ammunition, "Bring more, and save some abilities."

"Haha, that's what you said!" Fang Li was taken aback for a moment, then smiled, and reached out to take the bag.In the era when food and clothing have become a problem, the price of alcohol is also high.

"Of course!" Fan Lewen said.

The two watched Fang Li and Zhao Yu quickly join the team of supernatural beings, and it was impossible to tell who was who in the white protective clothing.

"Let's go, it will be our turn soon." Fan Lewen greeted Dong Guo.

Everyone gathered together, and the generals in neat military uniforms glanced at everyone, "This is a base built by the largest concentration of manpower and material resources in country Z, and it is also our last base." After a pause, "We have no way out, kill Go! Kill it!" The last roar came out.Countless people harmonized, and everyone was excited.

The red eyes and ear-shattering roar are not weaker than the zombies outside.

Fan Lewen and Dong Guoshun also received two tubes of medicine, carefully put them away, and breathed a sigh of relief, they did not expect to get this medicine under such circumstances.

When he raised his head and was about to talk to Fan Lewen, suddenly cascading and continuous sharp voices sounded. Most people around covered their ears in pain and collapsed on the ground. Some even rolled on the ground impatiently, with hideous faces.

Dong Guoshun noticed that the sound was like water waves, rippling in waves, almost forming substantial air ripples.

Following the ripples, he soon discovered that the sound started from the zombie birds surrounding the city, and the zombie birds that everyone thought had been suppressed actually had this hand.

I saw that all the zombie birds screamed loudly, raised their necks high, and neighed towards the sky. The sharp and piercing sound was not loud at first, but the sound seemed to be calling, and all the zombie birds stopped hitting and shouted in unison. Screaming, all the voices reached the same frequency, more and more birds, louder and shriller.

Sound frenzy!

Jiang Cen hammered down the table in resentment, could it be that if he really complied with his words, misfortunes never come singly? !

The observational data showed that this sound not only harmed the spirits of some ordinary humans, but the pressure on the glass above City B had begun to multiply.

Damn it, Jiang Cen's face is ugly. Once a small crack appears inside this kind of glass, it will cause the whole piece to crack, isn't it okay? !

"Quick, turn on the firepower, and then activate the second layer of protective cover." Jiang Cen's tone accelerated.

Everyone else watched as a metal cover was slowly closed from eight directions outside City B, closing in the middle of the sky.Like the petals of a flower slowly closing.

At this time, no one was in the mood to appreciate this moving scene. Everyone knew that the golden glass might not be able to hold it.

"Quick, Li Qiang is going to run away." Dong Guoshun suddenly pulled Fan Lewen's sleeve.

At this time, everyone's attention was focused on the group of zombies in the distance and the zombie bird in front of them, and the monitoring of Li Qiang was suddenly much weaker.Dong Guoshun also found out that he left some mental strength on Li Qiang's side last time.

For Li Qiang, Dong Guoshun really finds it strange. From the perspective of mental fluctuations, Li Qiang is still a genuine human being, because he has no desire for human flesh, but some things are a bit strange. Could it be the ultimate situation of zombie evolution? !

It’s just that the Institute’s attitude towards Li Qiang is really intriguing. The strict monitoring is actually a strong fear of him. If this is the case, why not simply solve him and keep him like this. If there is any research significance, it is too early It should be studied thoroughly, shouldn't it?

He has also seen researchers' fear and love for Li Qiang, which is simply contradictory.
