Bang bang bang!

The gunfire continued one after another, and the artillery fire exploded in the zombie group, but the progress of the entire zombie group was not slowed down.

The fighters on the front line continued to retreat one after another, and the weapons behind them had shrunk by more than half.

Even if they fired all the bullets, they still wouldn't be able to deal with so many zombies.

What to do?

Is there only one dead end?

In the midst of the battle, the soldiers of the 3322 detachment leaned on each other, stood with their backs to each other, laughed wildly and did not shoot.

Dense hordes of zombies, you don't need to aim at all, you can shoot one at a time.

"Bastard! Come on to me! I'm going to blow you up! ”

"Behind us are our beloved family, friends, who want to hurt them unless they step over our bodies!"

They are losing ground and retreating.

The zombie hordes rolled and climbed the city walls.

Step by step, the warriors stepped back, using all their weapons in turn.

"This bunch of filthy things! You're going to hell! ”

The monitoring room of the command center was silent at this time.

The chief let out a long sigh and placed his hat on the table.

"Ladies and gentlemen, it is my honor to work with you, thank you for your efforts for so long, we have done our best to do our best, and the base has been able to hold on for so long, thanks to the joint efforts of everyone."

He stood up and saluted.

Everyone's eyes were a little moist, and they took off their hats and saluted.

They deliberately changed into new clothes and waited quietly for the results to come.

In just a few hours, they tried to dig huge craters outside, plant bombs, and make traps.

But it's still hard to resist.

The state has taken out all the surviving warehouses and is trying to use the basements.

It's useless, it's all useless.

The basement is powerful, but it is not deep enough, and after tens of millions of feet have stepped on it, the basement will collapse, and those who hide inside will suffer more than death.

Suddenly, a loud roar came from the screen.

Bang!

Everyone suddenly raised their heads and looked at the screen in surprise.

"It's ......"

saw a huge missile fall directly into the zombie group.

In an instant, hundreds of thousands of zombies disappeared directly.

Such a huge weapon, such a powerful lethality, the end of the world would have been exhausted long ago.

No, even before the end of the world, they didn't have such a powerful weapon!

Where did it come from?

Boom!

There was another loud bang, and several missiles rushed into the zombie crowd again, followed by the sound of heavy footsteps, breaking through the smoke and smoke.

The mecha with its beautiful appearance and lines appeared in front of everyone's eyes.

The front-line soldiers, the superpowers, and the commanders in front of the screen all widened their eyes.

"What is this?"

"Yes, it's a mech?"

Each mecha is at least five meters tall, and there are almost ten mechs in a row.

Their hands turned into cannons, and their huge cannons fired towards the zombie horde.

The zombie reversed direction, shifted its target to the mech, and rolled towards the mech.

But this hard mechanical shell, even if they have iron teeth and copper teeth, they can't bite through, and the mecha just shook their feet, and easily dropped them all to the ground.

It's like a pack of ants besieging elephants.

The presence of ants is simply not capable of causing any damage to elephants.

The fighters on the front line have already looked straight in the eyes.

"Mecha? Isn't this thing only in science fiction dramas? How...... When did it become a reality? ”

"When did our country actually have such technology? This is not scientific! ”

The adepts looked up and laughed.

"Is this the secret weapon mentioned above? That's awesome, isn't it? ”

"Damn, I actually made a mecha!"

"Cow! Oh shit, call me! These bastards want to destroy the base and kill them! ”

The addition of mechs is simply a lore weapon.

Ten mechs quickly slaughtered the tens of thousands of zombies and changed the direction of the siege.

For a while, the line of fire created by the red flame blocked all the outer walls of the base, and the zombies who touched the line of fire were wiped out in an instant.

And the number of zombies in the line of fire is not large, and it is easily dealt with by those soldiers.

The fishy stench that permeated the air gradually disappeared.

base.

The people who hugged each other and cried seemed to feel something, and they raised their heads one after another.

And the people on the upper floors saw the mecha cannon fire outside the city wall, and the flames in their pupils were burning.

The entire Central Command embraced each other in celebration.

"They succeeded!"

"After the first level, I got the secret weapon, haha! The base is saved! ”

The chief breathed a sigh of relief, only to feel that his whole body was weak, and he felt dizzy in front of him.

Eventually, he persevered, and he took a deep breath.

"Turn on the radio, send the signal, turn on the TV station at the base."

At this time, the television set in the base, which had not had a signal for five years, suddenly turned on automatically, and the chief's voice filled the streets and alleys.

Footage of the battle on the front line of the base appeared on the screen.

The footage was filmed by helicopter.

"The people of the central base of the Dachuan country, I am Yi Sheng, the first head of the central base, and I will tell you the good news, the country has used a secret weapon, and our base has been saved."

Scenes of battle appear on the screen.

Outside the base is a living purgatory.

The tens of thousands of zombies gathered with each other, and just looking at the screen made people tremble for a while.

One can imagine how tragic it would be if so many zombies rushed into the base.

At this time, guarding the outside of the base, there was actually a row of mechas.

With a steel body, the cannonballs can be fired out without money, and a bunch of zombies can be solved in an instant.

Under the cover of this powerful firepower, it seems that zombies are not so terrifying.

Sure enough, all fear stems from a lack of firepower.

The innocent child pointed to the screen and said, "Mom, that's Ultraman." ”

The mother held the child for the rest of her life and cried bitterly.

"yes, Ultraman, they're here to save us."

The chief's voice flowed slowly.

"This mecha is the latest secret weapon developed by our country, this base defense battle, the curtain came to a perfect end, everyone is determined to have confidence in the country, next, the latest news, we will report on TV."

"In this last days, everyone has been able to persevere until now, and thank you for your trust in the headquarters."

In front of the screen, everyone burst into tears.

They never believed in miracles, but now, they do.

The roar of the mecha guns continued to sound, and the flames stained half of the sky red.

This operation to clean up the zombies lasted for two hours, and the crisis at the base was successfully resolved.

The gate of the base slowly opened with a bang, and ten mechs slowly walked towards the base with heavy steps.

And the people gathered around the door, and beheld.

The outside of the mecha was originally made of smooth and special materials, but now it is stained with mottled blood.

Several teams stepped forward to clean up the mecha and cleared out a helipad for parking the mecha.
