Even though the visual distance is still more than ten kilometers apart, and even though everyone should close all the car windows and lock them, you can still hear the intensive flapping of wings coming from behind.
One after another, the screams echoed in the air, and the originally weak voices gathered together to form a huge wave of sound, which made people's scalp numb.
When Yu Tian and Chen Niuniu saw this scene, they felt a suffocating chill coming out of their bodies.
This thing was none other than a group of first-order birds that Yu Tian and the others had encountered! It was these guys who destroyed the armed helicopter that attracted the zombie wave in the air.
"Damn it, didn't you fly outside the city?" Even Yu Tian couldn't think of any good way to deal with these guys, and hurriedly pressed the intercom: "Everyone listen, the communication is interrupted now, everyone lies down and remain silent,
Don't make any noise!"
Just after finishing speaking, the dark curtain above everyone's heads fell! The light outside the window was also blocked at this moment, as if it had entered the night early!
Bang bang bang bang!
Continuous sounds fell on the roof of the car, like dense hail falling from the sky. Countless mutant birds fell from the sky and completely surrounded the two off-road vehicles. The bird's claws rubbed back and forth on the roofs of the two off-road vehicles, making dense and harsh noises.
Sound. There were too many birds hitting the roof of the car, and the whole car was shaking.
Yu Tian and others strangled all the zombies near the subway entrance for safety reasons, but now these zombies have become the main culprits in attracting these first-order mutant birds.
First-order mutated birds kept swooping down to eat the zombies on the ground, feasting on the dried zombie meat. Their ashen pupils were filled with hunger and desire for food.
Whether the food is zombies or humans.
From time to time, a first-order mutant bird flapping its wings would hit the car window, frightening everyone. If a window was broken and even a little bit of a human breath was released, all the people in the car would be eaten by countless mutant birds.
No bones left!
Everyone didn't even dare to stay in the back seat of the car. They all lay down on the cushions. Yu Tian used lip language to communicate with Chen Niuniu and Yang Li behind him.
"The number has increased! There are so many more!"
The two of them also nodded. There had never been such a large number in Tiangong Nightclub before. Yu Tian also saw second-order mutant birds and even third-order mutant birds, which they had never seen before.
They are a mixture of multiple populations, which is why they have such a large scale. This kind of thing is as terrifying as a zombie wave. It eats wherever it flies, leaving no one alive!
Now Yu Tianzhen was extremely fortunate that everyone had cleared away the zombies within three kilometers of the hospital. Without the zombie corpses, the birds would not have gone to search for food and then discovered the hospital. Everyone had escaped another disaster by a strange combination of circumstances.
It's just that a few of them were really miserable.
"Quack quack quack!"
The first-order mutant birds that landed at the entrance of the underground passage were immediately attracted by the corpse odor and burning smell emanating from the subway entrance. They swarmed into the subway entrance passage while croaking.
However, Yu Tian found that only a handful of birds landed. Most of them chose to fly rapidly to the southeast, as if there was something over there that attracted them more.
Besides food, what else can attract mutant beasts these days?
Yu Tian suddenly felt his heart beating twice, as if he had missed something important, and that thing was dangling in front of him, but he couldn't catch it.
"Quack quack quack!"
The first-order mutant birds that flew into the subway entrance swarmed out again. Each mutant bird had a few pieces of minced meat on its beak. They spread their wings and flew into the sky, following the large army.
All the zombies on the ground around him had turned into the skeletons of Sen Bai.
Everyone secretly breathed a sigh of relief at this moment. Yang Li pressed her chest, which was being bullied violently, and whispered: "It's so dangerous and it's finally safe..."
Suddenly there was a thud above their heads, and a huge thing hit them hard. A pair of sharp claws protruded from the roof of the off-road vehicle. Then a bird head curiously appeared outside and outside the car window, raising its ashen eyes.
Looking inside through the car window with interest.
This is a huge white-headed eagle, but today's reminder is much larger than the eagle before the end of the world.
Yang Li covered her mouth tightly and did not dare to breathe. Although the off-road vehicle could not see inside from the outside, this guy stared at his reflection on the window, as if he could not understand the scene inside. The bird's beak gradually approached, and gently
Pecked at the glass.
Bang!
The glass made a soft sound, but fortunately it was not broken!
But Yu Tian's heart suddenly rose to his throat,
"Oops!"
Birds don't have much intelligence, so they are full of curiosity about everything. The reflection of the glass outside aroused this guy's interest! But now this interest is equal to killing them!
Chu Yue's face turned slightly pale, and the gun in her hand was already aimed through the glass at the head of the third-level mutant Pulsatilla.
If this guy pecks through the glass, Chu Yue can only kill it with one shot! But even if he kills it, the loud gunshot will definitely attract the attention of the birds that have not yet flown far away.
The soldier who was driving had already put his foot on the accelerator! Everyone's pupils were extremely nervous, and at this time, the mutated white-headed wind poked its beak over again.
Another blow, this time the glass cracked on the spot with a bang, but fortunately it was not broken, only dense spider webs of cracks filled the air.
But these cracks seemed to frighten the mutated Pulsatilla. It croaked wildly, spread its wings and kicked its legs into the air. The huge force of pedaling on the roof made the entire off-road vehicle shake from side to side.
"Quack."
The mutated Pulsatilla spread its wings and flew high, gliding away into the distance.
Everyone in the car finally breathed a sigh of relief at this moment. Chu Yue put down the gun, only to find that her whole body was wet with cold sweat.
"Fortunately, we are lucky."
Yu Tian wiped the cold sweat from his forehead and raised his hand to signal everyone to continue to be silent. It was not until there was no movement outside for five minutes that Yu Tian dared to get up and slowly look outside through the car window.
There was only the last trace of afterglow left in the sky, and the silence outside the car was terrifying. In the distance, you could still see the tail left by the departing black shadow. Occasionally, scattered mutant birds flew overhead, but it was no longer a cause for concern.
Yu Tian quietly opened the car door and walked outside. When he looked around, there was nothing, and the world seemed to have been washed.
"Everyone, get up, it's okay."
Everyone walked out of the car one after another, and everyone's face looked pale with lingering fear.
Looking at the tail of the birds that were already more than ten kilometers away, Long Wei swallowed: "The mutated birds are so scary? There are so many..."
Chen Niuniu said nervously: "No, will something happen in the hospital?"
These words immediately made everyone nervous. Long Wei immediately turned on the walkie-talkie, but the hospital had exceeded the maximum communication radius of the walkie-talkies in their hands!
"Don't worry, the hospital should be fine. If the birds found out about the hospital, they would have been diverted to the hospital long ago." Chu Yue's mind was also very clear.
On the way back, Yu Tian asked on the intercom: "Does anyone know what is there that can attract so many mutant birds?"
"I can't think of it." Long Wei shook his head.
"Maybe it's the high-tech entrepreneurship park over there? There are many factories over there. Maybe those birds are going for the zombies."
Yu Tian pondered for a long time, and only what Chu Yue said made sense.
It was already dark when the SUV rushed back to the hospital. Yu Tian put the recovered acid in the laboratory, and the three zombies contributed dozens of liters. Huang Binghua unscrewed the bottle cap and sucked a drop of it on with a glass rod.
Fan Yi's carapace suddenly made a clicking sound and thick white smoke came out.
The outermost layer of the thick carapace was quickly corroded away. Yu Tian took out the killing command and fired, and the entire carapace was blown into pieces by the first-order nightmare ammunition.
"The effect is better than expected!" Huang Binghua's face was full of surprise: "The acidity should still be excessive. I can find a way to prepare a diluent. After dilution, dozens of liters should be enough for us to use for a long time."
"Okay, you are responsible for the diluent, and I am responsible for researching this acid warhead."
