In fact, when the pilots received the order from their superiors, they already understood what to do, they didn't refute, they just silently let hundreds of newcomers return to the city, these young people are the hope of the future, send death to this kind of thing, just do it yourself, so the newcomers, including Wu Zhenyuan, were able to return to the city, and the rest of the pilots all rushed towards the mutant bird.

The fuel of the fighter jets has been almost exhausted, and the missiles and everything are all used on the tide of corpses, and today 10 million zombies were killed and injured, relying on the firepower that fell from the sky, and these fierce attacks on the zombies were almost unbearable.

It can be said that the corpse tide is completely incapable of resisting blows from the air, and there is no way except to be bombed.

The Corpse King can hide in a hole in the ground, but the Corpse Tide cannot.

And now the pilots have no means other than the fighter jets they fly, and the so-called dogfight is just an excuse. Now, the pilots have dragged on for 20 minutes with their lives, and these 20 minutes are enough time for Yanjing to issue an air raid siren.

The "Woo ......" air raid sirens resounded in the sky over Yanjing City, accompanied by the announcement of the radio on the street, everyone hid in their homes, the doors and windows were closed, the curtains were closed, the lights in the room were turned off immediately, and countless people hid in their homes, never daring to go out again.

The fighter who had returned to Yanjing before also took advantage of this time to replenish the ammunition, and when the fighter could use the automatic machine gun, it said that there were no more mutant birds to resist, and at this time, the mutant birds also entered the airspace of Yanjing from all directions, and after these mutant birds put down the zombies, they immediately flapped their wings and left, while the sky was not completely dark, the mutant birds wanted to transport the zombies into the city again.

At the beginning of the zombie outbreak, Yanjing City encountered danger, the survivors at that time could only hide at home, can only pray for the early arrival of rescue, such hope is not in vain, a week later, the country mobilized the army, all the zombies in the city were killed, street by street cleanup, at that time, everyone thought that Yanjing was the safest place.

And among the existing 10 million people in Yanjing, they basically think that Yanjing is the safest place, so they will come, after all, this is the capital, no matter what, it is impossible to fall here, as the old saying goes, do not suffer from widowhood and suffer from inequality, do not suffer from poverty and suffer from anxiety. Only safety is the most cherished thing for people, in other words, survival is the most important thing.

But now, the zombies were airdropped into the city by the mutant birds, and after more than half a year, the zombies reappeared in Yanjing, and the people hiding in Yanjing City also recalled the fear brought by the zombies, so they all stayed at home honestly, praying to God, worshipping Buddha, even if they believe in Christ, they must pick up the cross and pray, and everyone hopes that the danger will pass as soon as possible.

After the zombies were thrown into Yanjing City, they immediately spread and began to look for prey everywhere, it is impossible for zombies to smash open the door, but it is still very simple to smash the glass, even if every household has installed anti-theft windows, groups of zombies rush over, and they can also break the anti-theft windows and enter the house.

"Ah......h

"Help, who's going to save me!"

"God, Bodhisattva, please have mercy on us who are suffering, don't ...... Yes! ”

There were cries for help and screams one after another in Yanjing City, many people's windows were broken, and the zombies were like hungry wolves that had seen their prey, rushing in frantically, and finding the person who was hiding and began to bite.

Zombies are creatures infected by viruses, and their saliva also contains a large number of viruses, even if the human body has antibodies, but if a large number of viruses enter the body again, they will still be infected, and only evolutionaries and supernatural people will never be infected.

And the zombies who rushed into the room were not for the purpose of eating meat, after the zombies found the people who were hiding, they rushed up and bit them, and they didn't let go until humans became zombies, and these zombies also had a unified purpose, not only to cause chaos in the city, but also to develop the number of people in the city.

In a corner of the city, the corpse king with a scar on his face appeared on the ground, and there were tens of thousands of mutant birds that entered Yanjing, and this corpse king also took advantage of this chaotic gap to enter Yanjing City.

There was an endless stream of birds flying towards Yanjing from outside the city, each bird either grabbed a zombie or two zombies in its paws, and when they arrived in the city, they put down the zombies and turned their heads away, without entanglement at all, and seemed to be completely reduced to a tool for transporting zombies.

Many people in the laboratory are also confused, they have never heard that the corpse king can control other animals, the corpse king can only control zombies, and they can only do it by relying on ultrasound, why these birds can also be instructed by zombies now, this is completely incredible!

At dusk, Shen Feng had finished today's task of guarding the city wall, and was finishing eating with his soldiers, tonight's meal was still steamed buns and fried cabbage, and there was a little meat filling in the steamed buns, although the food was simple, but the most important thing was that there was no limit, everyone could eat enough, and everyone had no opinions.

However, at this time, a piece of bird droppings suddenly fell from the sky, which happened to fall on Yang Chang's shoes, and Yang Chang was angry at that time, pointing to the sky and scolding: "Bastard, I just wiped my shoes clean, and I was defiled by you!" ”

Seeing this, Lu Xian hurriedly hid the steamed bun in his arms and said: "That can't make my steamed bun dirty, but the army is not allowed to waste food, and when the guano falls on my steamed bun, I really don't know what to do!" ”

However, the strange thing is that Yang Chang, who has always been active, didn't say a word at this time, just raised his head and looked up, and the whole person was stunned.

Yang Chang is not a person with a good temper, and he likes to scold when he encounters troubles, but now, Yang Chang's whole person is like a fool, looking at the top blankly, without any movement.

Shen Feng couldn't help but look up, it didn't matter what he saw, the steamed bun was thrown away, and he stood up in shock, reached out and touched the weapon around, and finally grabbed Barrett. He couldn't believe his eyes, the sky above his head was black and oppressive, and it was all huge mutant birds, and after enhanced eyesight, he could still see these mutant birds clutching zombies in their claws!

After seeing this scene, Shen Feng reacted at the time, "It's miserable, the mutant birds have entered the city, and the zombies have also entered the city!" ”

Lu Xian also stuffed the steamed bun into his pocket, frowned and said, "Impossible, how can zombies and mutant beasts cooperate?" I've never heard of it, and besides, why are there so many mutant birds around? Obviously, you can't see ghosts in winter! ”

The corpse tide eats whatever it sees, even if it is a mutant animal, and the zombies eat it correctly, so many mutant animals in the city are forced to stay away from the city by the corpse tide. Similarly, mutant animals will also eat zombies as food, and the two are hostile to each other for a long time.

And now, it seems strange that zombies and mutant birds are acting together.

Shen Feng's face changed, and he immediately got into his tent, and found the illustrated book given to him by Professor Niu Baiye from under the pillow, there are many mutant birds in the sky, but among them, the birds with the most species are swans, geese, and white cranes, these three kinds of birds have the largest number, it is definitely not a coincidence, there must be some reason!

Shen Feng found the illustrated book of the three mutant birds, looked at it carefully, and finally found that the three birds had something in common, "They are all migratory birds!" ”

At this time, Shen Feng thought of the scene when he was forced to a dead end by the corpse king Ma Jingshuang underground, and Ma Jingshuang swore that as long as it was spring, he would definitely be able to break through Yanjing, at that time Shen Feng thought that this guy was bragging, so self-confidence, it was just arrogance.

But now Shen Feng understands, where is the corpse king Ma Jingshuang arrogant, he has obviously planned the air attack on Yanjing, why do you say that you can win at the beginning of spring? Of course, when spring comes, migratory birds will fly north, and at this time, zombies do not have to hide underground because of the temperature, and zombies will also come out of the ground.

In winter, because of food problems, migratory birds are all frozen soil in the north, especially in the Siberian plain, and there are no insects on the ground, so they can only fly south, and after successfully surviving the winter in the south, they will fly north back to their hometown!

Moreover, now that the end is coming, the mastery of the natural world by human beings has greatly decreased, migratory birds can take advantage of the current time to reproduce rapidly, after an autumn breeding, the number of migratory birds can definitely be called terrifying, no one thought that at this time, the zombies rely on mutated migratory birds to get the opportunity to attack Yanjing.

"Corpse King Atletico Frost, terrifying! I have already thought of the battle situation more than three months later, and used our habitual thinking to find the only way to attack Yanjing. Shen Feng muttered to himself.

When Shen Feng was still learning ground tactics, the Corpse King's side had already mastered the all-round combat methods, the ground was guarded by walls and guns, of course, it was indestructible, and there were also probes exploring underground all day long, and it was purely whimsical to dig tunnels without being discovered, so the only way to enter Yanjing was the sky!

Previously, everyone felt that the zombie side did not have the power of air attack, so they didn't care about the defense of the sky at all, after all, if the zombies could fly, they would have entered Yanjing City a long time ago. But now it seems that the zombies have not mastered the power of air strikes, but the time is not right and it is difficult to use!

Migratory birds all go to the south to spend the winter in winter, and it is completely impossible for zombies to fight smoothly in a low temperature environment, if they are reluctant to fight, it is estimated that they will all be frozen to death in the wild, so the corpse king is deliberately delaying time, and they will wait until spring to act, they are sure to enter Yanjing City!

When Shen Feng was pondering inside the tent, Lu Xian's voice came from outside the tent: "City Lord, Miss Chu is still in the city, what should I do now?" ”

Hearing Lu Xian's voice, Shen Feng woke up instantly, now is not the time to think about the problem of migratory birds, Chu Chaoyan is still in the city, if this is in danger, wouldn't it be miserable?

Although Chu Chaoyan claimed that his condition had been cured and he had been recuperating in the hospital for almost two months, Shen Feng still let Chu Chaoyan reluctantly stay in the hospital, at that time everyone thought that Yanjing City was the safest, and Shen Feng also thought so, but now it has been reversed, and the front line is the safest place, because there are soldiers all around, and it is impossible for zombies to get close at all, but there are zombies in the city.

Shen Feng walked out of the tent, threw Barrett to the side, and said to Guo Pinming: "Old Guo, quickly build me two long swords, I want to go to the city, and the matter here will be handed over to you!" ”

Guo Pinming heard Shen Feng's request, and did not dare to slack off, found two steel pipes, and immediately made two long swords for Shen Feng, before Shen Feng's long sword had fallen in the underground cave and underground river, so Shen Feng had no weapons to use during this time, and now that the situation is in crisis, Shen Feng is also worried that the effect of the wind blade in the city is not good, so he needs weapons to participate in the battle.

Shen Feng rushed out of the city with two long swords, the whole person turned into an afterimage, and disappeared in an instant, he wanted to go to the city to rescue Chu Chaoyan, he couldn't leave Chu Chaoyan alone, she didn't even have a little defensive weapon by her side, if she was targeted by mutated zombies or something, wouldn't it be troublesome?

At the thought of tens of thousands of zombies appearing in the city, Shen Feng shuddered, the enemy appeared in the city again, no wonder the hard fortress is often broken from the inside, but the hard fortress can only be broken from the inside!

As soon as Shen Feng left the station with his weapon, Shu Daping ran over panting with a dispatch, and said as he ran: "There is an order from the headquarters to mobilize supernatural abilities and elite evolutionaries to participate in the operation of encircling and suppressing the zombies in the city, Mr. Shen...... What about Mr. Shen? How...... Didn't see him? ”

Lu Xian spread his hands and said that it had nothing to do with me, and said: "Our city lord's ideological realm is relatively high, and he has always taken the protection of the people as his own responsibility, so ah, just now the city lord took the initiative to go to the city to participate in the rescue mission, you are late!" ”

Shu Daping looked at Lu Xian and Yang Chang and asked, "What about you?" As far as I know, a few of you are also Adepts, right? ”

Yang Chang shrugged, pointed to the city wall and said helplessly: "Then we will disappoint you, we still have to defend the city wall, besides, we are all personnel who actually command the battle, if we leave, who can command the battle?" So, ah, the city lord is on the line! ”
