Doomsday Yuan

The good news that the bird repellent worked was sent back to the base, and the command post was boiling.

At present, within sight, there are no other birds flying towards the direction of the base. The large force of the flock of birds is currently parked in the southwest of the base, near the water area where Xu Song and the others found the flock of ducks before.In addition, many birds fell into the former zoo of city b and near the moat.

After hearing the news, everyone in the base who was nervously preparing for the battle finally breathed a sigh of relief, and the information from the satellite photos made everyone even more excited—"Mutated insects and mutated birds are hunting each other?!"

Birds are the natural enemies of insects, and although this large group of migratory birds has undergone post-apocalyptic mutations, it seems that because of the need to fly, their size is not as large as that of land creatures, and they have not become too large.

Of course, its size is astonishing compared to similar creatures before the end of the world.

But compared to the army of insects in the urban area, they are brave enough to attack even mutated giant creatures, let alone these mutated birds that are not much bigger than themselves?

The mutated birds also welcome these mutated insects to take the initiative to come to their door for supper. This dense sea of ​​insects is simply a feast for them.

Migratory birds and insects are fighting, this is simply double happiness!There are also a large amount of equipment and materials in the urban area, which must be retrieved by human beings if they want to live well in the future.Now that the urban area is occupied by these mutated insects, it is difficult for the survivors in the base to go deep into the center of the urban area to retrieve those things recently, and they only dare to move around the periphery.

But now the migratory birds are here, that is, the natural enemies of those insects are here, just to help people control the number of those insects!

What's more, if the migratory birds can eat bugs to their fullest, I'm afraid they won't be so interested in attacking the human base after they find it tomorrow, right?

With this apprehension and anticipation, people went to sleep restlessly.

Everyone hoped that these migratory birds would head north after eating and drinking in the urban area. It was best to keep their appetites full, so that the survivors in the base would be spared.

When the next morning came, a large group of migratory birds took off from all directions one after another. They headed towards the north and the beautiful lakes where they lived in previous years.But what is disappointing is that it was only a small part of the migratory birds that landed in the urban area yesterday and clashed with the army of bugs.

And, what's even more frightening is - because these birds had tasted the sweetness of attacking the human base on the way north before, so they developed an almost hopeless interest and curiosity about the current base in City B Heart! !

The breath of human life is like a shining sign, attracting the army of migratory birds flying high in the sky!

"Turn on all the bird repellents!" An order came from the command post, and all the bird repellents in the entire base were running at the same time.

"Do you feel better?" Xu Song and the others never thought that this new type of bird repellent would have an impact on Yue Zheng.

This kind of bird repellent disturbs and frightens flying birds through sound waves.The human ear of ordinary people is almost indistinguishable from this sound.But this does not mean that people with supernatural powers like Yue Zheng will not be affected.

"It's okay." Yue Zheng frowned, trying to mobilize his mental strength and suppress the sensitivity of his ears.

This is really a disaster, who would have thought that this kind of bird repellent would have such a negative effect?Fortunately, the bird repellent interfered in the direction of the sky, and Yue Zheng was on the ground, so the impact on him was relatively small, but it would definitely greatly reduce his flexibility in fighting in the future.

"For a while, it seems that I can only attack on the ground." He couldn't jump up and attack like before, which greatly restricted his combat effectiveness.

Xu Song put the frozen wet towel on his forehead: "It's okay, you don't need to jump up, your marksmanship is so accurate, you can use the gun with your mother..." Before he finished speaking, a black army of birds had already appeared in front of him. within people's field of vision.

"...there are so many, even if you stand on the ground and hit randomly, you can definitely hit a few of them." The corners of Xu Song's mouth twitched involuntarily.

Once the bird repellent was turned on, Yue Zheng was definitely not the only person affected by the ability in the base. Many people with hearing abilities fell down and lost their combat effectiveness.The news was sent back to the headquarters, causing all the bosses in the command post to almost vomit blood.

"This...why didn't you know about this situation before?"

"Reporting chief, when the experiment was done, people with hearing abilities were not allowed to assist in the experiment..." The news of the migratory birds came so urgently, and they were put into production before they had time to study whether they would have any negative effects. Are you looking for people with hearing abilities to assist in the experiment?

"Fortunately, the combat power of hearing-type supernatural powers is not too high... let's replace those people."

No substitutions?What else can I do?Especially for the defenders on the surrounding walls, the bird repellents on the top of the buildings in the city can all radiate to the walls. If the hearing department is still staying on the walls at this moment, it is simply courting death!

There was a chaotic change of personnel, and a black, tidal wave of birds had flooded over the base!

The bird repellent can indeed affect some birds. When they want to descend to attack the "food" on the fence, they are suddenly disturbed by the sound waves!Some birds with smaller bodies, weaker bodies, and extremely sensitive hearing even fell straight down!

But when the group of migratory birds reacted and hovered to a certain height, the effect of those bird repellents could no longer work on them!

The migratory birds who were suddenly attacked were outraged, and after circling twice in the sky, relying on the large number of birds, the "air attack" began!

Ever since birds had powers, land creatures have been in bad luck.They can arbitrarily throw all kinds of abilities downward in mid-air, whether it is water ball, fire ball or other mutant skills, as long as you close your eyes and throw it down, the creatures below can only dodge around to avoid injury.

Now, the base really can hardly withstand the "air attack" of this group of birds!

The bird nets and power grids prepared earlier, like the bird repellent, are completely useless because of the distance problem!The base's original plan to use bird repellents to relatively peacefully drive away these "passing" birds completely fell through.

"Bah bah bah!" The sound of guns fired, extending from the outermost periphery into the interior of the base.Although it was blocked at the beginning and attacked only near the southern outer city wall, the bird has wings, but after a while, almost everywhere inside the base was damaged by the flying bird's ability.

What's even more frightening is that after hearing the gunfire and smelling the smell of blood, the army of migratory birds gathered here continuously!

"Prepare to attack." Yue Zheng frowned and said to Xu Song and the others when he saw some flying birds hovering over Area A.

Their car was parked next to the command post, and the top of the car was covered by a once thick earth wall, leaving a few things like gun holes.This was temporarily built by the earth-type supernatural beings to help them, and the invisible part inside was covered with a layer of diamond vines planted by Tian Cheng.

At this time, Xu Song and the others were guarding this "bunker", defending against the air.

"The distance is too far, change to a sniper rifle." Yue Zheng calculated the distance, and found that the pistols he usually used couldn't hit the flock of birds hovering so small that there were only a few spots left.Of course, there are also ones that fly relatively low, but they are also very difficult to shoot.

After hearing the sound, Mother Xu took a sniper rifle and filled the chamber with empty shells.

For this defensive battle, the 0246 team specially ordered a lot of spare bullets.And because of the cooperation, the base also distributed them a lot of weapons and bullets.

Compared to Xu's mother, Yue Zheng used regular bullets.The two occupied a shooting hole for a while, and began to snipe at the sky.

Xu Song stood at a relatively large opening and fired his shotgun rockets into the sky.

There are more and more birds in the sky, and the dark clouds cover it like a black cloud.

All kinds of abilities and small stones were thrown downwards, and many bird repellents were broken under this violent projection.

Even if the army has a machine gun, it is almost impossible to stop this group of crazy birds.Even weapons such as anti-aircraft guns and mortars still cannot stop their attacks on the ground.

When those bird repellents were destroyed in sevens and eights, the bird bombs began to dive down to the ground.

The screams sounded in all directions around the base one after another, and the enlarged body prevented these birds from dying with just one bullet.Even the birds that were beaten and fell down still have the strength to attack humans with their sharp beaks and claws.

There is blood everywhere, and there are battles everywhere. This post-apocalyptic Garden of Eden, in the battle between two creatures, is gradually soaked in blood, as if incarnated into Shura Hell.

Switching from the sniper rifle to the pistol, Mother Xu's arms became sore due to the recoil.Yue Zheng is relatively much better, the mutation of the strength system makes his stamina extraordinary.After those bird repellents were smashed by the flock of birds, the sounds that would have disturbed his hearing and thus affected his brain were gone.

Now that the flock of birds descended, he could switch back to his original fighting style without worrying about being affected by it.

Abu and the two ostriches also left the temporary bunker with Yue Zheng and Xu Song at this moment. Abu used the power of the wind system to jump up from time to time, grabbing a bird that accidentally fell, and directly smashing their necks. bite off.

Two ostriches followed Abu, and when the birds were attracted by Abu, they pecked them quietly and made a blood hole in their bodies.

"Area No. [-] can't hold on anymore, the bullets are consumed too much, and the flocks of birds in the sky are still endless!"

"Area No. [-] can't hold on anymore, the equipment is seriously damaged!"

"Tanks, tanks were overturned by them!"

Bad news came from the communicator from time to time. The faces of the people in the command post were gloomy, and some people's legs were trembling slightly under the table that others could not see.

"Chief..."

"Withdraw...withdraw underground..." Mr. Wu closed his eyes and sighed softly, the flock of birds was too huge.They all underestimated how bloodthirsty the flock was this time... Yes, if it was a flock of birds before the end of the world, once they were attacked or frightened, their first choice would be to flee collectively.But now, even though they know that there is a threat to them below, they still refuse to leave...

"All evacuated, all evacuated!"

After the news came, those people who had long thought of retreating breathed a sigh of relief and moved towards the various underground entrances.

In the base, people with little combat capability, as well as some equipment and instruments that were afraid of being damaged, had been evacuated in succession when the air-raid shelter was just built a few days ago.

Most of those who stay outside are members of various supernatural teams, or middle-aged men and women with certain combat effectiveness.

But now, it seems that the ground above can no longer be defended...

When Yue Zheng and the others got the news, they withdrew to the gate of the conference room. Yue Zheng killed the wild geese that had just fallen nearby, and picked up the walkie-talkie: "There is no danger outside, you can come out."

Mr. Wu and the others came out of the meeting hall, raised their heads in a hurry, and found a large white net above their heads. Before they could figure out what it was, they saw a supernatural bomb dropped by an unknown bird from the sky. While exclaiming, the supernatural bullet fell into the big white net, and was instantly evaporated without a trace...

"Let's go!" Yue Zheng reminded a few people who were still in a daze.

The guards escorted the big guys into the underground passage in a hurry, and Yue Zheng retreated to the caravan.

"Let's go in too?" The family members and scientific researchers of important personnel in Area A also hid in early.At this moment, all the defenders were evacuated.

"Well, even if we can still guard here, I'm afraid we won't be able to guard it for too long. If we are surrounded by those birds..." Before Yue Zheng finished speaking, he suddenly raised his head, frowning and looked towards the west.

"what happened?"

"The sound of the wings... seems a bit different from these birds."

Xu Song immediately released his mental strength, and was surprised to find that two larger birds were flying from the west, and... "Looks like... an eagle? Or a vulture?"

No matter what it was that flew over, the two immediately turned around and returned to the bunker.Seeing the two of them coming back, Xu's mother hurriedly asked, "Shall we leave too?"

"Well, an advanced air-raid shelter." Yue Zheng nodded and walked to the cockpit.

"Remove the Vajra Vine in a while." Xu Song stroked Tian Cheng's hair.

Tianyou leaned over and said, "There are two amazing ones over there!"

"West side? Are those two eagles?" Xu Song raised his head, just as Yue Zheng drove the RV out of the cover, and through the birds in the sky, he had already seen the two black dots getting closer and bigger ...

The huge iron gate was rumbled shut, and the electronic locks were locked layer by layer.

The space in the air-raid shelter is not small, and there are facilities such as vents, special channels for electric wires, and water channels.In terms of the reaction time of this incident, it is really rare that the air-raid shelter can be built so well in such a short moment.

However, it is said that there are several air-raid shelters in Area A, which have been built at the same time since the base was first established.Especially the one where Xu Song and the others are now, there are even separate rooms. This is not a temporary air-raid shelter dug out outside. A large group of people can only huddle together, sitting silently on the ground and counting the days with their fingers. .
