After Luo Fei ascended the star, mobilized troops began to ascend the star.

Whether it was Wang Hu, Li Biao, or the new recruits, they were not far from being promoted. As the battle progressed, people began to successfully upgrade.

The number of zombies below has dropped to only half. It seems that this defensive battle is about to succeed.

But the crisis arose at this time.

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

Luo Fei and two mobilized soldiers opened fire at the giant zombie at the same time. The bullets hit the giant zombie with jingling. Although there were blood stains, they could not cause fatal damage.

Even the bullets from Bayi Bar hit the forehead, but they failed to penetrate its brain!

"This is an iron armored zombie!"

Ye Fan killed this zombie with a name. The layer of cuticle outside this thing is even tougher than iron plates.

The iron-armored zombies attracted firepower, and the zombies behind immediately flocked to the front of the hotel.

The iron-armored zombie had no way out, so she waved her big claws and began to push the minibus.

The powerful claws directly penetrated the body of the minibus, and it was almost to tear the minibus from the middle.

"No! They can't let them destroy the minibus. If the car didn't block the door, they would be able to rush upstairs."

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

A fireball exploded inside the corpse group.

The iron armored zombie is located in the center of the grenade and is washed down by the explosion airflow.

Broken glass flew everywhere, and Ye Fan hurriedly lowered his head to avoid it.

When the smoke and dust dissipated, many zombies were left around, with broken limbs and broken arms.

But the iron-armored zombie at the center of the explosion actually stood up again shakingly.

There are many broken and bleeding areas on the body, but this kind of damage is ineffective for zombies. As long as it does not penetrate its brain, it can crawl even if only half of its body is left.

"Sir, the damage effect of grenades on zombies is not particularly ideal. The protection of the iron-armored zombie is too high. Unless there is a large-caliber sniper weapon, it will be difficult to kill it."

Ye Fan nodded, feeling a little anxious.

"Is there no way to kill this thing?"

"There is also a way, that is, continue to use mining cars. Whether it is an anti-aircraft machine gun or an armor-piercing incendiary bomb, it should be able to kill it. However, there are too many abandoned cars here, and the accuracy of the anti-aircraft machine gun is not guaranteed. The armor-piercing incendiary bomb is too lethal. Direct bombing may cause an explosion of cars around it, unless we are given some time to clean up the cars here."

"Okay, you and Li Biao will drive and clean up immediately and act as soon as possible. We can support it here."

"clear!"

Xu Haoran immediately greeted Li Biao, and the two of them jumped out of the window, jumped to the mining cart, opened the lid from the raised part and drilled in.

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

At the beginning, I was not prepared enough and I should have cleaned up the abandoned vehicles nearby before taking action, but now I am in crisis.

The most urgent task is to block the iron-armored zombies outside the door.

If they were rushed upstairs by zombies, although they would not be wiped out, casualties would be inevitable.

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

Ye Fan suddenly thought of something.

"Why did I forget this thing!"

He hurriedly opened the Red Alert Page.

The four options on the Red Alarm Page are: Main Building, Defensive Building, Soldier Unit and Mechanical Unit.

There is a wall inside his defensive building.

In the Red Alert game, the role of the wall can block the breakthrough of the soldier units. No matter how many soldiers are, they cannot break through the wall. Only by relying on the chariot can they be bombarded.

If a wall is built at the door, I believe that blocking the zombies is not a problem.

After clicking on the wall, Ye Fan was stunned for a moment.

Because after the fence is opened, there are three types: Fence No. 1, Fence No. 2, and Fence No. 3.

When he was playing games before, he saw something, and was a little confused, so he immediately said to Nana: "Nana, what is the difference between these three walls? Let me introduce it as quickly as possible."

"Sir, the No. 1 fence has a height of 3.5 meters and a thickness of half a meter. It has a reinforced concrete structure. Barbed wire can be installed on it, but soldiers cannot climb the fence to snipe. The cost per meter is 20 gold, and the addition of barbed wire fence will increase by 5 gold per meter."

"The second wall is five meters high and one meter wide. Soldiers can snipe at the wall, and the length is 100 gold per meter."

"The third wall is ten meters high and three meters wide, with a mercedes. Soldiers can climb the wall to snipe, and the length is 500 gold per meter."

No need to explain more, Ye Fan already understood, it turned out that the wall was upgraded with the system.

The three types of fences should be able to cope with different situations, especially the No. 3 fence, which is ten meters high and three meters wide, has an overall reinforced concrete structure. Not to mention zombies, tanks may not be able to penetrate.

If a base is established, such a wall will be the greatest guarantee for survivors' lives.

Of course, Ye Fan is not using wall No. 2 or 3 now, and wall No. 1 is enough.

Although the iron armored zombies are aggressive, the 3.5-meter-high and half a meter-thick wall is definitely something it cannot break through.

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

"Produce two meters of wall immediately."

"Okay, do you need to install a barbed wire? But now you don't have a physical power plant, and the barbed wire cannot be powered on to become a power grid."

"No, just the wall is enough."

"Please wait, 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."

He took Luo Fei downstairs and arrived at the first floor door. Ye Fan saw that the minibus had been torn apart.

The iron-armored zombies had already squeezed into the minibus. When they saw Ye Fan and Luo Fei through the glass on the other side, they seemed to be crazy, and they roared in their mouths, waved their arms, and shattered the glass.

"Sir, be careful, they are going to rush over!"

Ye Fan was not afraid of it, it was fake. The hideous face of the iron-armored zombies and the roars of the surrounding corpses made him nervous. He might be a zombie manure.

But he had to stop the corpse group from advancing and buy time for Xu Haoran.

"Open fire! Knock them some!"

Luo Fei was a brave soldier. He stepped forward with a quick step. The Bayi Bar began to shoot continuously, and the drums rotated, and the shells jumped out of the gun one by one.

Da da da da da da da ~!

It is difficult for this kind of gun to kill the iron armored zombie, but it is still possible to repel it. The iron armored zombie was knocked out two meters away.

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

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

The iron-armored zombie, stimulated by food, pounced forward again, and moved rapidly. She tore open another bus of the minibus with her claws and was about to rush into the gate!

Ye Fan could even feel the bloody smell in the mouth of the iron armored zombie. He was less than half a meter away from the iron armored zombie at this moment!

Don't care about the threat in front of you and act quickly.

Open the defense page, click on the fence, and place it!

Boom~!

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

The noise of the zombies outside seemed to be blocked.

Ye Fan breathed a sigh of relief, and could even hear the sound of 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!

Lighter ignites.

Hiss ~!

A smoke ring was sprayed out.
Chapter completed!
