Da da da da da——

Li Yu carried a heavy machine gun and kept shooting at the zombies pouring in through the gate.

The bullet slanted out of the gun's muzzle as if it were free of charge.

Li Gang, Li Tie, and Shouhou rushed upstairs and started shooting at the zombies from upstairs.

On the other side, Yang Tianlong and Cannon used their guns to shoot at the zombies that poured in through the gaps in the two walls.

In the distance, the huge gunshots here attracted the attention of the surrounding zombies, and they rushed towards this direction.

For a time, the blocking of bullets and the zombie swarm formed a strange balance. The zombies were unable to penetrate the fire net, and as the zombies rushed in one after another, the gunfire never stopped.

"One, two, three, push!" Lao Luo and Xiao Ding and Xiao Liu pushed the heavy cannon back.

The rotor of the helicopter is too big, and it is easy for the cannonball to hit it when it is fired.

After Lao Luo and others pushed the heavy cannon aside, Lao Luo quickly raised the barrel of the heavy cannon and shouted to Xiao Ding and the others: "Go and lift out the cannonballs!"

Amidst the gunfire, Xiao Ding asked loudly: "How much do you want?"

Lao Luo turned his head and said angrily: "Everyone! Hurry!"

They had to be fast, because they were able to set up heavy artillery here with peace of mind, all because Li Yu and the others were there to help withstand the impact of the zombies.

When Li Gang arrived upstairs, his scalp felt slightly numb after seeing the scene in the distance.

There are just too many zombies.

Bang bang bang!

He quickly squatted down and shot at the zombies that had just rushed in.

A total of fifteen people came on this trip, excluding the three Lao Luo who were bombarded by heavy artillery and Zhu Xiao who kept evacuating in the helicopter at any time. Together with Li Yu, a total of eleven people were blocking the zombie attack.

Together they blocked the two collapsed gaps in the wall and the open door.

The door has long since disappeared, otherwise we can find a way to close the door to reduce the number of zombies coming in.

Li Yu was carrying a heavy machine gun while shouting at Lao Luo behind him: "Lao Luo, hurry up! Hurry up! Our bullets are consumed too fast and we can't hold on for too long!"

In the sub-zero weather, Lao Luo was sweating profusely.

He kept moving his hands, raising the height of the gun barrel, changing its direction, and took out from his arms several position parameters that his third uncle had told him before.

Calibrate carefully.

Although he was urged by Li Yu, he still remained calm.

The more anxious you are, the easier it is to screw up.

Once the position parameters are set, one calibration can save a lot of time.

He ignored Li Yu and focused entirely on the heavy artillery. He seemed to have forgotten where he was, and the zombies around him were also ignored.

"Reload!" Lao Luo adjusted the shooting angle of the heavy artillery and shouted to Xiao Liu.

Xiao Liu and Xiao Ding lifted the cannonball together, slid it into the track, and pushed it up.

Bang!

Reloading completed!

"Calibrate again!"

Lao Luo strictly followed the order of using heavy artillery and did not dare to be careless.

"Calibration completed."

"put!"

boom!

The recoil of tens of tons of heavy artillery caused the ground to sink somewhat.

The heavy artillery also moved ten centimeters back.

"Recalibrate!" Lao Luo yelled at Xiao Ding and Xiao Liu.

Even though some anti-shock boards were placed on the ground, there was too much snow a few days ago and it has now condensed into ice.

After the gun is fired, the ground will sink due to the shock, and the recoil will easily move the gun body backward.

If it's a mortar or other small-caliber artillery, it's okay. Due to the small caliber and small recoil, and the function of the buffer mechanism, it can also be fired continuously.

But this kind of ultra-long-range and powerful heavy artillery is different. The recoil is astonishingly large.

so.

After each firing, the heavy cannon must be pushed back to its original position and recalibrated.

Phew~

The shells flew north in the direction of the Confederacy.

Seconds later, the shell struck the southern Union wall in the north.

"Reloading completed!" Xiaoliu roared.

"Calibration completed!"

"put!"

In less than thirty seconds, another artillery shell hit the southern wall of the Northern Federation.

same location.

In just tens of seconds, it was bombed twice.

Crash--

A large area of ​​the wall collapsed, and the guard who was standing on it was instantly blown into pieces of flesh and blood, and fell towards the bottom of the wall.

"continue!"

Lao Luo and the others repeated the operations just now, as if they were machines, constantly calibrating, reloading, calibrating again, and firing.

Above the Confederate Wall in the North.

Yin Xi heard a huge explosion, and then he felt the vibration of the wall and was shocked.

what happened?

Didn't Han Li just go out with a helicopter to chase people from Oil City?

Another group of people appeared out of nowhere!

At this moment, a subordinate stumbled over from a distance.

"Chief of Guards, our wall was bombed again..."

Before he finished speaking, there was a violent shaking accompanied by an explosion.

Yin Xi immediately rushed towards the direction of the explosion. Before he could get closer, he saw another shell hitting the wall dozens of meters away.

The aftermath knocked him down completely.

He looked at the wall not far away in horror. At this time, a huge gap appeared, and nearly one-third of the wall was penetrated.

The zombies below seemed to become more excited because they heard the explosion, and rushed towards the gap.

Boom!

Another cannonball hit the middle and lower part of the wall.

Crash--

Due to the lack of load-bearing capacity in the upper part of the wall, the cement bricks continued to fall down.

Ruined!

This is a rhythm that is going to be broken through!

So he quickly shouted to the surrounding guards: "Contact the guards in other directions and come over here. The wall may be broken, hurry!"

His subordinates' expressions changed, and they quickly went out to communicate, asking people from other directions to come over for support.

The shelling continues.

Governor's Palace.

It was originally located at the highest position in the Northern Federation. From the window sill of the Governor's Mansion, you can overlook everything on the outer wall.

After Yuan Zhi heard the second shelling, he immediately ran to the terrace on the top floor of the Governor's Mansion.

"This is!!"

He looked at the outer wall where a huge gap had been blown out, and his eyes were about to burst.

Oil City, people from Oil City again!

"Send people to support quickly, don't let the zombies rush in!" Yuan Zhi shouted to Ma Song behind him.

Ma Song left in a hurry.
