A mass of zombies surrounded the entire base, and they were not afraid of death, like machines that never stopped, they kept climbing towards the city walls.

Soon, the zombies also seemed to find that their attacks could not help the wall at all. On the contrary, all the zombies crowded under the city and became a living target for the warriors.

The slaying GIs roared and slanted their fire downwards in an attempt to kill more zombies. It seems that they want to explode the hatred that has been suppressed in their hearts for a long time, and it is these zombies who are the object of revenge.

Roar!

Just then, a strange sound came from the zombie horde. After the sound sounded, these stupid zombies suddenly became smarter. Instead of wasting their strength to destroy the wall, they tried to stack a man-made ladder with their bodies to climb to the top of the wall.

Upon discovering the enemy's attempt, Alger was taken aback and immediately ordered all his soldiers to attack the hordes of zombies stacked with Arhats first!

"Attack, give me concentrated firepower, I must not let any zombie rush to the city wall!" Seeing that these zombies were so smart that they stacked Arhats, Alger immediately began to get nervous. That feeling of being on his back told him that if he let any of the zombies rush up the walls, they were doomed!

Unfortunately, there are so many zombies that you knock one down and immediately another climbs up.

It felt like the worst nightmare, surrounded by endless zombies that couldn't be repelled no matter how hard you tried!

A large number of warriors gathered at the foot of the city wall, desperately using their weapons to attack these Arhat zombies, trying to drive them out of the city.

A wild beast without reason, a survivor with the last hope, on the other hand, is engaged in a life-and-death struggle on top of this narrow wall. Every now and then, some warriors are torn to shreds by these zombies that rush to the city.

What's more, he was injured by the zombie's virus-carrying claws, and in just a few minutes, he transformed into a zombie and attacked his comrades in turn.

Seeing that there was already chaos on the city wall, Yun Qi sighed and said, "It's almost, if you go down, this place will become a dead city." Activate the defensive artillery and destroy these zombies!"

"In addition, order the sniper team to find the zombie who just made a strange sound, the other party is likely to have a certain amount of intelligence, kill the leading zombie, and the rest will not be a problem!"

After receiving Yun Qi's order, the people below immediately began to act.

Buzzing~

I saw that on the top of the city wall, a large gap suddenly opened, and an 88-mm self-propelled anti-aircraft gun slowly rose.

Three fighters worked at the same time to push the self-propelled anti-aircraft guns to the edge of the wall, and then controlled the base of the anti-aircraft guns so that their muzzles were facing downward. One gunner sat in the firing compartment, and the other three were responsible for transporting the chain of shells to this anti-aircraft gun!

Boom Boom!

The massive anti-aircraft guns finally began to shoot slowly. Purely mechanized operation, the accuracy of shooting depends solely on the skill of the personnel. Although the hit rate is not satisfactory, but the current situation needs to be targeted?

Beneath the city walls is a dense crowd of zombies. These anti-aircraft gun shooters, just fire desperately at the place where the monsters are most!

The 88-millimeter high-explosive armor-piercing shells, each as thick as a water cup, are terrifying weapons capable of hitting an altitude of 8,000 meters and smashing bombers with one shot.

And when used to deal with zombies, the effect is simply a massacre!

Each shell pierced the bodies of dozens of zombies, eventually penetrating deep into the ground, causing a violent explosion.

The stratum corneum on the surface of these zombies, which can withstand small arms, is useless in the face of these large-caliber anti-aircraft guns, and is easily penetrated like a blank sheet of paper.

Haha, die, die! you abominable zombies.

The anti-aircraft shooter who killed the gun pulled the trigger and frantically launched a fierce attack on the zombies below. Every shell can kill dozens or even hundreds of zombies.

Countless red flames almost engulfed the entire zombie colony.

Twenty of these anti-aircraft guns swept almost the entire zombie group, and these zombies who were not afraid of death were completely crushed by this pure and extreme violence!

Seeing these big guys appear at the last moment and sweep through the zombie horde with unstoppable momentum, all the soldiers are demoralized!

Under Alger's command, these high-spirited GIs fought their way to the enemy and drove down all the zombies that had climbed the walls.

With the ferocious fire of the anti-aircraft artillery, after nearly ten minutes of indiscriminate bombardment, these zombies finally retreated.

The sniper team was never able to find the location of the zombie leader, but under the indiscriminate bombardment of the anti-aircraft artillery unit, the leader hidden in the zombie group was killed along with it.

And without the command of the zombie leader, these stupid zombies lost their cooperation and completely became a target-like existence.

When the smoke cleared and saw the zombie corpses all over the ground under the city walls, all the warriors roared excitedly!

"Hooray, we won!"

"We're victorious!"

"Destroy the zombies and take back our human world!"

Seeing that the morale of these survivor warriors was all high, Yun Qi nodded with satisfaction. After this battle, these people can be regarded as some iron-blooded soldiers.

And with these people as seeds, Yun Qi believes that he will soon be able to bring out an army of survivors, sweep away these zombies, take back the planet, and find the cause of the zombie annihilation!

Three months have passed in a flash!

After that zombie siege, the size of the base has increased several times. Yun Qi picked up almost all the survivors from several surrounding cities.

But unfortunately, the satellite city where the spaceship might exist was empty! Only a large number of spaceship builders who had not yet had time to escape were discovered by Yunqi. However, Yun Qi was not discouraged, he believed that he would be able to find a way to make the jump engine.

At present, this base that has been turned into Dawn City by the survivors has a population of nearly half a million, of which the number of legions composed of survivors has exceeded 100,000! The ratio of the army to the common people has reached 1:5.

This ratio almost reaches the carrying limit of the entire base!

If it weren't for the large amount of military supplies provided by the fleet, the economy of the entire Dawning City would have collapsed long ago.

In this forbidden area of science, almost all electronic technology is banned. That's why Dawn has developed another unique tech tree.

You know, before the end of the world, this was a high-tech human world that had developed into an interstellar civilization.

Even in the event of an apocalyptic apocalypse, with fewer than one survivor, there will still be a large number of engineers and technical experts who will survive.

These people were unified by Yunqi to work with the fleet's scientific team to research new mechanical technology.

This somewhat unique and even extreme new technology was born, and even a new technology route was added to the infinite cards, called steampunk technology!

Looking at this special technology tree composed of multi-steel riveting and gear transmission, Yun Qi couldn't help but sigh a little, as long as human beings master the scientific method, it is a forbidden place for science, and human beings have a way to regain the power to conquer the world!
