After Luo Fei ascended to the star, mobilized soldiers began to ascend to the star one after another.

Whether it is Wang Hu and Li Biao, or those recruits, they are not far from ascending to the stars, and as the battle progresses, people continue to succeed in ascending to the stars.

And the number of zombies below has dropped to only half, and it seems that this defensive battle is going to be successful.

But the crisis arose at this time.

The mutant zombies rushed to the door, Luo Fei and Xu Haoran each knocked down one, but the largest giant zombie and the other two quasi-giant zombies still rushed to the front of the minibus.

Luo Fei and the two mobilized soldiers fired at the giant zombie at the same time, and the bullets clanged on the giant zombie, although there were also blood stains, but they could not cause fatal damage.

Even the bullet hit the forehead of the Bayi bar, but it failed to penetrate its brain!

"This is an ironclad zombie!"

Ye Fan gave this zombie a name, and the cuticle on the outside of this thing was even tougher than an iron plate.

The ironclad zombies attracted the firepower, and the zombies behind immediately swarmed and crowded in front of the hotel.

With no way to retreat, the ironclad zombie waved its two big claws and began to push the minibus.

The strong claws directly penetrated the body of the bus, almost tearing the bus apart from the middle.

"No! they can't be allowed to destroy the minibus, if it weren't for the car blocking the door, they would have rushed upstairs. ”

Xu Haoran immediately took out a grenade from his waist, pulled the pull ring and threw it down.

A fireball exploded inside the corpse.

The ironclad zombie was located in the center of the grenade, and was knocked down by the blast current.

Broken glass flew all over the sky, and Ye Fan hurriedly lowered his head to dodge.

When the smoke and dust cleared, there were a lot of zombie corpses left around, with stumps and broken arms.

But the ironclad zombie at the center of the explosion staggered to its feet again.

There are a lot of broken and bleeding places on the body, but this kind of damage is ineffective against zombies, as long as it doesn't penetrate its brain, even if it has half of its body left, it can still crawl.

"Sir, the damage effect of the grenade against the zombie is not particularly ideal, the protection of that iron-armored zombie is too high, unless there is a large-caliber sniper weapon, it is difficult to kill it. ”

Ye Fan nodded, a little anxious in his heart.

"There's no way to kill this thing?"

"There is also a way, that is, to continue to use mining vehicles, whether it is using anti-aircraft machine guns or armor-piercing incendiary bombs, it should be able to kill it, but there are too many abandoned cars here, the accuracy of anti-aircraft machine guns is not guaranteed, the lethality of armor-piercing incendiary bombs is too great, and direct bombardment may cause the explosion of surrounding cars, unless we give us a little time to clean up the cars here." ”

"Okay, you and Li Biao immediately go to drive and clean up, act as soon as possible, we can support here. ”

"Understood!"

Xu Haoran immediately greeted Li Biao, and the two of them jumped out of the window again, jumped onto the mining truck, opened the lid from the raised part and got in.

The two of them went to clean up the site, but Ye Fan was a little anxious.

At the beginning, I was not well prepared, and I should have cleaned up the abandoned vehicles in the neighborhood before acting, but now it is in crisis.

The top priority is to keep the iron-clad zombies out of the door.

If they are washed upstairs by zombies, although they will not be wiped out, casualties are inevitable.

"What should I do? The minibus won't last long. ”

Ye Fan suddenly thought of something.

"How did I forget this!"

He hurriedly opened the red alert page.

There are four options on the Red Alert page, which are the main building, the defensive building, the soldier unit, and the mechanical unit.

His fortifications are walled inside.

In the Red Alert game, the effect of the wall can block the breakthrough of the soldier unit, and no matter how many soldiers can break through the wall, only the chariot can blast away.

If a wall is built at the entrance, it is believed that it will not be a problem to block the zombies.

After clicking on the wall, Ye Fan took a look.

Because after the wall was opened, there were three kinds of walls, the first wall, the second wall, and the third wall.

When he was playing a game before, he saw one and was a little confused, so he immediately said to Nana: "Nana, what is the difference between these three walls? ”

"Sir, the No. 1 fence is 3.5 meters high, half a meter thick, reinforced concrete structure, and barbed wire can be installed on it, but soldiers cannot climb the wall to snipe, the length cost is 20 gold per meter, and the installation of barbed wire adds 5 gold per meter. ”

"The No. 2 wall is five meters high and one meter five wide, and soldiers can climb the wall to snipe, and the cost per meter of length is 100 gold. ”

"Wall No. 3 is ten meters high and three meters wide, with battlements, soldiers can climb the wall to snipe, and the length costs 500 gold per meter. ”

There is no need to explain more, Ye Fan already understands, it turns out that the wall has also been upgraded with the system.

The three types of walls should be able to cope with different situations, especially the No. 3 wall, ten meters high and three meters wide, with an overall reinforced concrete structure, not to mention zombies, I'm afraid tanks can't penetrate it.

If a base is built, such a wall is the greatest guarantee for the lives of the survivors.

Of course, Ye Fan doesn't need the No. 2 or No. 3 wall now, and the No. 1 wall is enough.

Don't look at the iron-clad zombies, the 3.5-meter-high and half-meter-thick wall is definitely something it can't break through.

I looked at the door of the hotel on the first floor, and the width was about two meters.

"Produce a two-meter fence at once. ”

"Okay sir, do you need to install barbed wire? It's just that now you don't have a physical power plant, and the barbed wire can't be electrified as a power grid."

"No, the walls will do. ”

"Wait a minute, it will take twenty-five seconds. ”

Ye Fan said to Luo Fei beside him: "Come with me to cover me, and the others will continue to snipe." ”

ran downstairs with Luo Fei, and when he arrived at the door of the first floor, Ye Fan saw that the minibus had been torn open.

The iron-armored zombies had already squeezed into the bus, and when they saw Ye Fan and Luo Fei through the glass on the other side, they seemed to be crazy, roaring from their mouths, waving their arms, and breaking the glass with a click.

"Sir, be careful, they're coming!"

Ye Fan was not afraid in his heart that it was fake, the hideous face of the iron-armored zombies, and the roar of the surrounding corpses made him nervous, and if he didn't do it well, he would become zombie dung.

But he had to stop the corpses from advancing and buy time for Xu Haoran's side.

"Fire! Knock them off some!"

Luo Fei was a brave warrior, and an arrow stepped forward, and the Bayi bar began to shoot in bursts, the drum rotated, and one by one bullet casings jumped out of the gun.

Dada~~~~~!

It is difficult to kill the ironclad zombie with this kind of firearm, but it is still possible to repel it, and the ironclad zombie was forced to retreat two meters.

At this time, the inner wall of the system has been produced.

Ye Fan gritted his teeth and rushed over, and Luo Fei retreated, leaving the space at the door to Ye Fan.

The ironclad zombie stimulated by the food pounced forward again, moving quickly, tearing open the other car of the minibus with both claws, and was about to rush into the gate!

Ye Fan could even feel the bloody breath in the mouth of the iron-armored zombie, he was less than half a meter away from the iron-armored zombie at the moment!

Ignore immediate threats and act quickly.

Open the defense page, click on the wall, and place!

Bang~~~!

A huge wall, two meters long and more than three meters high, appeared out of thin air, from the first floor directly to the ceiling, poking holes in the ceiling!

The hustle and bustle of the zombies outside seemed to be cut off all of a sudden.

Ye Fan let out a sigh of relief, and could even hear the sound of the iron-armored zombies roaring against the wall on the other side of the wall.

He sat down against the wall, took off his hat, wiped the cold sweat from his head, and then took out his cordyceps from his pocket.

Clang!

The lighter ignited.

Hiss~~~!

A smoke ring erupted.

It's cool.
