The gunfire just now attracted more zombies from the woods to the north, and the outside of the castle was already crowded...... No, the sea of zombies, the zombies in the back row crowded the zombies in the front row, squeezing the bodies of some zombies who crowded to the side of the city wall.

In the midst of this crowding, there was a slight 'click' of the closed gates, and then more of the same sound appeared, but the soldiers inside the castle did not hear it because of the howls of the zombies.

The wires broke one after another, and in the next moment, the big iron gate of the castle suddenly fell off the door shaft, and was pushed down to the ground of the castle courtyard by the zombies that had been congested near the big iron gate. Some of the zombies in the front row fell to the ground along with the gate, and a large number of zombies behind them surged into the courtyard with their bodies!

"The iron gate is broken! They're rushing in! ”

"Full fire! Hold the gates! Be sure to guard the gate! George yelled on the wall.

The soldiers in the courtyard and on the city wall immediately opened fire when they heard the order, and several heavy machine gun barrels also stuck out from the windows of the central castle, and the metal barrage tore apart the dozens of zombies that poured into the gate in an instant, but more zombies outside the city wall stepped on these torn corpses and poured into the courtyard.

Among them is a giant mutant zombie!

“FUCK！ This thing doesn't kill with a headshot! ”

"Help!" A soldier was grabbed by the mutant zombie's hands, and in the midst of a burst of screams, his stomach was bitten by the mutant zombie, and his body was broken into two with both hands.

But the soldier was still not dead, and continued to let out even more terrible screams.

The recruits on the ramparts trembled, instinctively firing into the crowd of corpses.

"Stand back, everyone! With a grenade! ”

Or the veterans in the yard are calmer and more experienced.

With a deafening explosion, the mutant zombie's body was shattered and fell to the ground.

The poor soldier finally stopped screaming.

The battle is not over.

Behind the fallen mutant zombies, more zombies rushed in the direction of the gate like a tide.

"On the city walls! Hit that big guy with rockets! Don't let the big guys get near the gate again! ”

"Central Castle machine gun fire cover! The people in the courtyard retreated to the central castle and held out! ”

Captain George fled from the city walls in a hurry, directing the battle between the old and new soldiers in the walls and the courtyard.

"We were abandoned."

The recruits on the city walls were terrified, but they had no choice but to load, reload, and shoot mechanically.

The zombies in the woods on the opposite side are simply endless, kill as many as you want, the corpses under the city wall have been piled up three or four meters high, forming a big slope, and if they continue to pile up, these zombies can step on those corpses and climb directly onto the city wall!

The veterans and commanders in the courtyard, supported by strong firepower, retreated together to the central castle.

The iron doors of the central castle slammed shut.

The recruits on the city walls were also in complete despair.

They knew they were abandoned, but they couldn't surrender to their enemies.

This is a war that cannot be stopped once it has begun.

Unless one side is all dead.

The recruits could only use their weapons to shoot at the bottom of the walls with mechanical and numb movements, and then watched as the corpses piled up outside the walls.

Another mutant zombie appeared on the concrete pavement.

A rocket flew over, blasting it and dozens of zombies around it into the air.

A brief clearing formed at the point where the rockets landed, and then quickly filled up with a wave of corpses around them.

The machine guns in the central castle were all muted, apparently under the orders of Captain George to save ammunition.

George was going to hold in the central castle, hiding in the central castle without making any sound, waiting for the tide of corpses to recede on its own.

The recruits on the city wall did not dare to stop, and once they stopped, those zombies who were not afraid of death would step on the pile of corpses below the city wall and climb above the city wall.

Now the height of the pile of corpses is close to six meters!

At this moment, two mutant zombies came out of the woods.

"Rockets! Fast! Launch! ”

"Rockets are running out!"

"Concentrate your fire, don't let the two of them come over!" One of the recruits yelled at the others in a hoarse voice.

In just half an hour of fighting, they have learned to forget their fears in extreme fear.

Maybe it's numbness, maybe it's survival instinct.

Because, fear is useless, and you can only survive by continuing to fight.

A mutated zombie was torn to pieces by a barrage of metal and fell to the ground under their concentrated fire attack. But the other mutant zombie rushed to the side of the city wall with a barrage, grabbed the edge of the city wall with two claws and jumped onto the city wall!

"Bang bang! Bang bang! Bang bang! ”

The recruits retreated, numbly pulling the trigger and attacking the mutant zombie.

More zombies took advantage of the opportunity to climb the walls, and while the recruits were gathering fire to lay siege to the mutant zombies, they pounced on them from behind or side, knocking them down on the walls, and then gathered around them, tearing their bodies to pieces in their screams.

Finally, the city walls were quiet.

A large number of zombies rushed into the courtyard of the castle, screaming and crowding.

In the central castle, someone finally noticed the iron gate of the castle.

The iron door seems to have been damaged, and the door shaft is not connected by strong thick screws at all, but tied to the door shaft with several thin wires through the screw holes!

Such an iron gate is nothing at all!

'Horn! Trumpet! Trumpet! With a few small sounds, the iron gate of the central castle could not withstand the push of many zombies outside, and the fragile iron wires were broken one by one, and the iron door was pushed to the ground in an instant.

"Shoot! At the main entrance! Full fire! ”

Captain George's panicked voice.

On the balconies on the third floor and on the roofs of the fourth floors of the castle, several mortars were erected.

More windows probed out of the barrel of a heavy machine gun.

The gates of the central citadel were breached, and no amount of ammunition was left to be used.

"Boom!"

"Boom!" "Boom!"

The mortar shells fell among the corpses, lighting up the sky at the same time, and at least dozens or even hundreds of zombies turned into broken limbs and flew into the air with a single shell.

The tongues of fire from the heavy machine guns spewed out, and the firing range was quickly cleared out of the open space by the metal barrage, and then filled up again.

The endless zombies make the bullets of these heavy machine guns seem to shoot into the water, no matter how ferocious the firepower is, once the firepower does not reach the ground, there will be the same or even more number of corpses as before.
