The fog is thick.

With the Northern Federation as the center, all the zombies within a radius of two hundred kilometers are concentrated here.

On the roads, in the woods, and in the city, shadowy zombie groups were like a hundred ghosts walking at night, walking towards the direction of the Northern Federation.

And at this time.

As heavy fog spread over the northern border for nearly twenty-four hours.

Under the outer city wall, millions of zombies have gathered.

And they are stacked to a height of thirty or forty meters.

The searchlights on the outer city wall were turned on, but the northern border was too big and there were too many zombies, so it was still difficult to see clearly.

The inner and outer cities were in chaos.

"Ma Song, I just couldn't contact the governor. We need support at the outer city wall. Please send someone over quickly. The zombies are about to climb up."

In the fog, Yin Xi's forehead was covered with sweat, and he yelled crazily at the walkie-talkie.

Sizzling——

There is no feedback from the intercom.

He has lost contact with the Governor for three hours.

Four hours ago, the inner city wall gate was opened, and the governor sent Liu Wei, Chao Yuan, Wang An and others to come here to support.

But after the inner city gate was opened, in an instant, people from the outer city took advantage of the fog and rushed into the inner city.

Even though some of them were shot with firearms, it was hard to see clearly in the fog.

The turbulent flow of people rushed into the Northern Federation.

chaos.

Total chaos.

There were only a dozen people on the inner city wall at this time.

They still used a hanging tower to hoist it up, but before they could repair the steps, heavy fog hit, and a wave of zombies followed.

The northern border was completely plunged into chaos.

In the Northern Federation, many lights are turned on.

Some people also thought of spraying liquid nitrogen, but as soon as the liquid nitrogen was produced, the way was blocked by crowds rushing from the outer city.

These people from the outer city are like wild wolves who have been hungry for a long time and turned into devils. They are constantly robbing food in the inner city and killing everyone they see.

In their words, we are going to die anyway, so we might as well eat and drink enough before we die.

The reason why the Northern Federation was able to resist waves of zombies before was.

That's because they control the inner and outer city walls, and the zombie waves don't arrive that fast, giving them a certain amount of time to react.

The most important thing is that even in the rain, they can still see their surroundings clearly.

Affected by internal and external troubles, the large Northern Federation is as fragile as a baby at this moment.

The threat of heavy fog is so great that even a base as powerful as Da Zhangshu has allowed spies to take advantage of the loophole and run into the inner city despite being well prepared.

What's more, Yuan Zhi is a mixed bag and has not yet completely controlled the inner city walls.

The Governor's Palace was stormed by refugees from the outer city a few hours ago.

His whereabouts are still unknown.

Yin Xi on the outer wall of the city was secretly anxious. He wished he could leave here immediately and return to the inner city to find his wife and children.

But he can't. Once he leaves, there will be no commander on the outer city wall, and it won't be long before the zombie wave breaks through.

Da da da da da——

Gunshots continued.

They almost don't need to aim, they just need to shoot under the wall, and they will definitely hit the zombies.

"Liu Wei, can your artillery team bomb again? There are too many zombies." Wang An picked up the walkie-talkie and shouted frantically.

A large part of the artillery team led by Liu Wei is on the inner city wall of the Northern Federation.

But all the steps of the inner city wall were destroyed, and they had to repair the steps before they could go up.

But the fog and zombies arrived in such a hurry that they didn't have time...

"Fire the JB cannon, there is no field of view at all, and long-range bombing is meaningless. Let's use bombs to blow up the zombies under the wall." Liu Wei said angrily.

The zombie tides are stacking up, but the Northern Federation is still a force that has been able to resist countless zombie tides.

The level of toughness is extraordinary.

They gritted their teeth and resisted the zombies. Even though they were worried about their families in the inner city, they could not go back at this time.

Just like what Chief of Guard Yin Xi said to them just now, if the outer city wall cannot resist, everyone will die.

A few hours later.

The number of zombies is increasing.

There are already some places on the fence where zombies have climbed onto the fence and are biting the people above.

Since the field of view is really limited, even all the lights are turned on.

But in this foggy environment, you can't see clearly whether the person in front of you is a person or a zombie.

In the gray environment, only a single figure could be seen a few meters away.

The zombies are also standing, so it is impossible to tell whether they are team members...

Many times, the team members who were standing next to them one second were dragged away by zombies the next.

But I can't see clearly.

This sense of fear in the mist swallowed up all the people on the wall like a tide.

Click!

A combatant was shot out of bullets.

He quickly shouted to the team member next to him: "Tianmao, give me a magazine."

"Tianmao!"

"Grass!"

The man heard cries for help everywhere, his hands trembling slightly.

If there is someone by his side, he can continue to persevere.

But at this time, no one could be found around him.

"A natural disaster like a dog's day, a zombie like a dog's day!"

The next second, he felt a black shadow appear in front of him.

"who?"

There was no answer, and he quickly pointed his gun at the black figure.

The black shadow was very fast and rushed towards him.

He fired quickly.

Click!

He suddenly realized that he had no bullets.

So he turned his head and ran to the right desperately.

But after running a few steps, he bumped into something.

And this thing is a zombie that is biting humans.

Of course, this zombie was not polite to the food that was served to him.

Click!

He bit off his finger in one bite.

A few fingers chewed in the mouth of this ferocious zombie.

This zombie was unusually tall. While chewing the man's fingers, it held his body tightly with its hands.

"Ah ah ah, help, help, I don't want to die..."

"ah!"

Following a shrill scream, there was no more sound.
