Outside the base.

The tens of millions of zombies have been killed, and their vanguard troops have reached the defense line of the outer ring city.

Smelling the smell of human flesh from afar, the zombies were excited. There was a roar, and the voice was louder and louder, and it shook the sky.

In the eyes of these brainless zombies, the millions of humans in the base are just moving cans of meat, still fresh, fat and juicy. Whoever catches them will have a feast and feast.

They roared loudly, stinky yellow drops of saliva coming out of their foul mouths, and spread their arms and claws to pounce impatiently at the cans of fresh meat in front of them.

"Fire, fire! Kill them! Outside the defensive line, a commanding officer shouted hoarsely with a command knife, and sweat mixed with mortar ran down his chin on his red face, not knowing whether he was nervous or afraid.

Although the forward force of zombies cannot be compared with the large army, there are tens of thousands of zombies. The groups of zombies, crowded one by one, were densely packed, and they were all black and black from a distance.

They rushed at them with their innumerable arms like trees, their bloody mouths full of fangs, and screaming. The bullet hit them like a drop of rain into the sea, and then disappeared in an instant, almost to no avail.

They weren't afraid of pain at all, and when the bullet hit them, they didn't feel anything except for a pause. One arm is broken, and they have another arm stretched out; Break a leg and they can crawl on the ground; Piercing the stomach, they dragged their intestines and continued to walk????? They are almost impossible to kill the best stormtroopers. As long as their heads are there, they won't stop attacking.

The fresh meat in front of them is constantly tempting them, and it is worth it for them to pay any price in order to eat humans.

This can be seen from their drooling and their excited expressions.

"Bastard, hit the head, only these zombies can die if they hit the head. You two-handed! "Officers on the front line kept weaving through the crowd of guards, shouting and reminding the soldiers, the militias, of how to shoot.

Probably because of the first time I saw so many zombies attacking together, the people on the defense line were a little scared.

At first, I almost forgot that the weakness of the zombie's head was the head, and picking up the gun was a ping-pong fire, and as a result, most of the bullets either hit the zombie's body or flew away. Few hit the zombie's head.

It was only after the urging of the officers and experienced veterans that they remembered to shoot the zombies in the head. But at this time, there were not many bullets to be given to everyone. And there are still a lot of follow-up bullets that have not been delivered.

At the gate of the Central City, there were still a lot of people crammed there, and it was difficult for soldiers to enter and exit, and ammunition and weapons could not be transported at all.

In front of the battle, in addition to the thousands of corpses that fell from those zombies, there were many zombies rushing up one after another.

"Fire, fire, throw grenades!" Realizing that the soldiers' militia had few bullets, the commanding officer immediately ordered.

In an instant, artillery shots, missile shots, and even grenades all dragged sparks towards the zombie horde in front of them. After the smoke passed, the position left patches of charred corpses and pieces of flesh. There aren't a few zombies left standing.

"Great, we're winning, we're winning!" The soldiers, the militia fighters all stood up and clapped and cheered each other, in a good mood.

In their hearts, human beings are always the proudest, and the zombies in front of them are just a pile of cannon fodder without brains!

"Huh-" But before they could be happy, they heard a strange zombie roar again.

Immediately afterward, a large group of black-pressed birds descended into the air.

Their red eyes, long wings, and sharp claws shone on the heads of the soldiers and officers in the army's defense line, scratching, scratching, and chattering. It's so fast that people can't be caught off guard.

There was chaos in the defensive position, with gunfire and zombie birds screaming. In the end, each of the big birds grabbed a human and flew away.

"Look, zombies, zombies are here again!" After the chaos, most of the people had not yet recovered and gasped for breath, and a sharp-eyed man pointed outside the line and shouted.

In the distance, there were a large number of tens of thousands of zombies surrounding them, and they couldn't see the end at a glance. The fangs and claws swooped down on them viciously.

"Oh my God, there are so many of them, they can't be killed, they can't be finished. We're done, run! "After a vigilante group was raided by zombie birds, he left a shadow in his heart. At this time, seeing so many zombies rushing over, the defense line in my heart finally collapsed. Trembling, he threw down his gun and ran towards the city gate without hesitation.

He ran well, and many people in the People's League began to follow him, and they stopped defending the line, and a large group of hula lala threw down their guns and fled without their lives.

"Come back, come back, leave your post without permission and rectify the Fa on the spot!" The officers roared and tried to stop the militia from escaping, but most of them lost their armor and fled.

On the battlefield, there were only tens of thousands of disciplined regular army soldiers and a few militia fighters who were not afraid of death.

Outside the position, the figures of the zombies are getting closer and closer. There are not enough shells anymore, and there are not many bullets. There are no guns, no cannons, and these ordinary people are in front of these zombies with sharp teeth and claws, who are not afraid of fighting and dying, they are given for nothing.

The north wind was blowing, but the rumbling footsteps of the zombies in the distance were getting closer and closer. No one thinks that the defense line is still holdable, and they are destined to be food for the zombies.

The pressure was getting bigger and bigger, cold sweat broke out on the foreheads of the soldiers, their hearts were constantly beating, the steel guns in their hands were pinched, and their knuckles were white.

They were also afraid, and they wanted to run, like the militias. But there are still nearly a million refugees behind him who have not yet been evacuated to Central, and they can't retreat!

"Get on the bayonets, we'll fight them!" At the critical moment, the gray-haired base commander arrived, and in his hand was a steel gun with a shiny bayonet.

Xiao Yi lowered his glasses and lowered his eyelids.

He originally wanted to go to the front line with the base commander to fight the zombies, but the base commander did not allow him to go.

As the patriarch of the Xiao family's faction, he has the obligation to protect the safety of the head of the family.

The commander knew that this time he was fighting with the zombies. Xiao Yi is the only heir of the Xiao family in the future, so naturally he can't be sent to death. Even if Xiao Yi was already about to reach the third order, he couldn't take this risk.

Pursing his slender and thin lips, Xiao Yi seemed to have made up his mind, and turned around and walked towards the base experimental cave behind the mountain.

Experimental cave.

It was still that laboratory, and Shen Feifei was still lying on that iron bed. It's just that at this time, the glass cover on the bed is gone, and three of the five restraints on the body are missing.

The laboratory is no longer as lively as the experimenters used to come and go.
