"Boom!"

The walls collapsed.

Yang Chen, who had his eyes closed, touched his gun for the first time, and then looked outside.

The sky was already slightly bright, and in the dim light, countless zombies were like ants, crossing the first wall that had become ruins, howling and rushing towards this side.

Tall mutant cows, dense force T3 zombies, zombie hedgehogs full of spikes, and many zombies with unnamed names rushed into the city in a swarm. But apart from the bodies of some fallen soldiers, there was not a single living person around.

The tide of zombies instantly flooded most of Chengdu City, and the zombies in front had approached less than 1,000 meters of the ancient city wall.

Boundless zombies, violent and fierce. Yang Chen's face became extremely pale, this weak line of defense could not stop the impact of the zombie army at all. These people are just used to buy time for the people behind to retreat.

Looking at the army of zombies getting closer and closer, everyone in the room couldn't help but tremble.

"I don't want to die! I don't want to die! ”

A soldier next to Yang Chen howled, threw away his gun and ran towards the back.

"Smack!"

The pistol in Ma Shan's hand went off. "No one can retreat without an order. You wonder why we have a troop behind us, and tell you, it's the Overseers. If you spot a deserter, kill them on the spot! Ma Shan glanced at the people around him, and slowly inserted the pistol back into his waist, "Prepare to fight!" ”

"Click, click!" A machine gun was ready to shoot at any time, and Yang Chen also suppressed the fear in his heart, and slowly aimed the muzzle of the gun at the zombies that were getting closer and closer.

"Boom!"

The cannon rang out, and the army of zombies that were charging was knocked down in a large area.

The sound of the cannon was an order, Yang Chen pulled the trigger hard, and the heavy machine gun suddenly spit out a spear flame more than half a meter long. For a moment, the deafening sound of gunfire drowned out all the sounds around it.

The zombies at the front are all speed-type T3 zombies, and their defensive capabilities naturally can't be compared with those thick-skinned and thick-skinned power-type zombies. Countless bullets weaved into a dense barrage, and one zombie after another fell with convulsions. The charging zombie army, like the sea meeting a reef, came to a sudden stop.

Everyone knew that if they didn't stop the zombies, they would have no way to escape. Everyone exerted their combat effectiveness to the extreme, and the long chain of bullets rattled, and one bullet after another angrily shot out of the muzzle. While shooting zombies, you also take away your own fears.

Fight to the death! There is no escape!

The heavy artillery troops, who had rested for a few days, tried their best to shoot a small part of the shells that had just been produced into the zombie group, and the individual cloud burst shells exploded in the zombie army continuously.

Under a frenzied will, millions of troops, relying on a more humble city wall, miraculously withstood wave after wave of attacks from zombies.

Fierce fighting began at 5 a.m. and lasted until 3 p.m. The dead zombies were piled up again into a hill.

"It seems possible to withstand the attack of zombies." Although he had been fighting non-stop for nearly 10 hours, and even the hand that pulled the trigger was a little numb, Yang Chen's heart slowly calmed down. Among these attacking zombies, there are neither zombie birds, nor long-range zombies such as zombie hedgehogs. If you just rely on some zombie rats and zombie dogs, this million people can definitely stop it.

"Knock knock~! Knock knock~! The ground trembled slightly, and there was a muffled sound like thunder.

"What sound?"

Everyone asked in their hearts, and the vibration continued for more than ten minutes, and it was getting closer and closer.

"What's that!!"

Yang Chen opened his big mouth, and the machine gun in his hand was forgotten.

The mountain of corpses in the distance was brutally pushed away. Dozens of behemoths appeared before their eyes. The whole body was covered with brown leather armor, a long nose stretched forward, and the most frightening thing was two fangs three or four meters long.

"This is a zombie elephant? There is no elephant so big, it is better than a dinosaur. Why are there elephants in the east? ”

These behemoths that are at least eight meters tall and more than ten meters long are mutated zombie elephants. The largest one was about the height of the 12-meter-high wall.

Yang Chen's pupils couldn't help shrinking to the extreme, and the machine gun in his hand was aimed at the zombie elephant. And most of the soldiers on the entire city wall also pointed their machine guns at the zombie elephants.

"Dada~~!!" The machine gun roared again, but what made Yang Chen desperate was that countless bullets hit the zombie elephant, only to bounce a series of sparks. The zombie elephant that was shot by countless bullets, wrapped in sparks, still rushed towards the city wall step by step.

"Knock !!"

There was a piercing sound of gold and iron, and one of the smaller zombies stumbled and seemed to take a step back. But it's only a step back. The armor-piercing shells that can shoot mutant cows can't penetrate the leather armor on the zombie elephant.

"Knock knock!"

The zombie elephants are not fast, but no one can stop them. Armor-piercing shells, incendiary eggs, all tried. Unless it is a large-caliber gun of more than 150 mm, but the heavy artillery unit will not be able to hit it at all.

"Knock knock!!"

Closer, the zombie elephant was less than 100 meters away from the city wall.

"Ah~~!!"

Finally, a soldier couldn't help but jump, turned around and ran backwards. The first soldier to flee was like a fuse. Suo, ignited the fear in everyone's hearts. Large-scale routs can no longer be stopped.

Ma Shan shot two deserters and watched as more and more people turned and fled. sighed helplessly, and ran outside with two people.

It's messed up, all the lines of defense are out of order.

Yang Chen threw down the machine gun, picked up a Type 95, took Che Xun Tianyu, and ran towards the bottom of the city wall.

"Don't fall, be careful!"

How easy it was for millions of people to escape the walls. Although there is a small gate every 100 meters leading to the city, there are so many people fleeing that this small gate is simply not enough.

So, the soldier, who was still a comrade-in-arms one moment, pointed his gun at the person in front of him the next moment. Gunshots rang out one after another inside the city walls, but unfortunately, the bullets were fired at the soldiers who had been blocking the zombies for nearly two months.

"Boom!!"

The earth shakes and the mountains shake! The zombie elephant crashed into the city wall with great momentum.

Although the ancient city wall is 12 meters high and more than 10 meters thick, it is an antique from 600 years ago, and although it has been urgently repaired, it is not as good as the first city wall made of strong concrete.

"Whoa!!"

The city wall collapsed, and the nearly one-kilometer city wall that was hit by dozens of zombie elephants turned into a pile of ruins for the first time, and the city wall next to it was also affected. Bricks fell one by one, and large holes appeared in the walls.

"Phew!"

Yang Chen and the others, who were almost buried by the city wall, stood up with a disgraced face. Without Yang Chen's reminder, he slid down the city wall along a broken hole, and ran desperately towards the nearest Yangtze River Bridge.
