Sky Island Survival: I am the only one who has played MC Sky Island

Yang Fan has made sufficient preparations, both in terms of personnel and ammunition.

An output of 20 personnel a day and countless ammunition are enough to set sail and fight a defensive battle.

Just when Yang Fan was full of confidence that such defense could hold off the tide of zombies until the bomber formation completed the mission of destroying their nest.

Suddenly, a strange and loud roar came from the zombie group.

Unlike other sounds, this time the cry was very dull, somewhat like the sound of machinery operating.

"Gun helicopters take off, see what that noise is."

Yang Fan's heart was shocked, and he felt something was wrong about the voice.

You know, his intuition has always been very accurate. Whether it was when he encountered the Free Alliance before, or when the Eternal Night World was attacked by monsters, his premonitions were very accurate.

As Yang Fan gave the order, an armed helicopter took off from the base and flew towards the rear of the zombie group in the distance.

Watching the helicopter take off, Yang Fan's heart was gripped with grief, and soon the pilot on the helicopter sent back a message.

"Lord City Lord, a group of extremely huge zombies appeared behind the zombies. They were more than 20 meters tall."

The helicopter pilot reported with a trembling and somewhat surprised voice.

"A new zombie has appeared? I didn't expect these islanders to have such a trump card."

"Try to attack and see the defense power of these zombies."

Yang Fan ordered the helicopter crew to attack. If the monster was just huge in size and had average defense, then there was nothing to be afraid of.

But if, in addition to its strong size, its defense is also amazing, Yang Fan will need to change his strategy.

His wall was only 10 meters high and could not stop such a huge monster.

Moreover, there is only one tank deployed on the outermost wall to kill the opponent's key leaders. Once encountering zombies with higher defense, there will be no way out.

"Okay, Lord City Lord."

As the pilot responded, a rocket flew towards a giant zombie rushing in the front in the wave of rockets on the right side of the plane.

Compared with ordinary mutated zombies, this giant mutated zombie has a larger body and thicker armor.

And their size is twice that of ordinary mutant zombies.

Ordinary mutated zombies are only 10 meters tall, while this giant mutated zombie is only 20 meters tall.

And the scariest thing is that the head of this zombie is almost completely covered by fake jumps, and you can't even find the position of the eyes when looking from the front.

It was like a heavy bulldozer, rushing towards the direction of Yangfan.

As the rocket flew towards the giant mutant zombie in the front, it exploded with a bang, and the entire zombie was engulfed in smoke and dust.

Just as everyone was still expecting what kind of damage this shot could cause to the giant mutant zombie, suddenly a huge head rushed out from the smoke.

At the same time, a blackened mark appeared on this huge bone skull.

"Sure enough, it didn't work. Rockets are very effective against light targets, but they are not that effective against heavily armored targets like this."

Yang Fan felt a little disappointed, but also relieved. After all, rockets rely on fragments to kill and do not have the effect of penetrating armor.

"Helicopters continue to monitor the city, all ground infantry ready shoulder-fired anti-tank missiles."

Yang Fan felt that the only tank posed no threat to these dozens of giant zombies.

Therefore, the role of the first line of defense is still to delay the speed of these zombies.

At the same time, Yang Fan was also dispatching a large number of tanks to the middle of the first and second lines of defense.

Once the giant mutated zombies break through the first line of defense, they will be faced with the threat of hundreds of tank guns.

You should know that when a tank gun fires an armor-piercing shell, its penetration is more than 1000 mm.

Even the strongest bones can be penetrated easily by armor.

Yang Fan then gave an order to all his tank troops to stand by between the first and second lines of defense.

At the same time, only a few minutes later, these giant mutant zombies were already within the range of the rocket launchers on the city wall.

"Everyone aim at the giant mutant zombie."

Yang Fan gave the order and at the same time aimed the only tank nearby at the leading mutant zombie.

"Load an armor-piercing bullet and test the zombie's defense."

Yang Fan was still a little worried as he was not sure about the zombies' ability to withstand tank gun armor-piercing shells.

Therefore, he must know the zombies' ability to resist tank guns.

500 meters, 400 meters, 300 meters.

When these giant mutant zombies approached the city wall within 300 meters, with Yang Fan's order, countless shoulder-fired rocket launchers fired rockets.

These rockets trailed white smoke and flew towards the giant mutant zombies in the distance.

At the same time, the tanks also fired shells.

The huge noise raised a cloud of dust, and the tank armor-piercing shells instantly reached the giant mutant zombie in front.

This time, there was no huge smoke and dust like previous rockets.

The fin-stabilized armor-piercing discarding sabot projectile does not have the ability to explode.

Instead, it only left a tiny hole in the zombie's skull.

It was just this small hole, but a large amount of blood spurted out of it like a dam releasing floodwater.

At the same time, the giant mutant zombie that was hit staggered and its head hit the ground directly.

It was obvious that this armor-piercing bullet hit the zombie's brain, making it unable to move.

"Beautiful and effective."

Through the telescope, Yang Fan saw the effect of the attack. He was sure that armor-piercing bullets could cause damage to this giant mutant zombie.

At the same time, those shoulder-fired rockets also arrived in front of the giant mutant zombies.

Boom boom boom.

The noise was deafening and the smoke was everywhere

As the shoulder-fired rockets fell, the giant mutant zombies also suffered considerable damage.

These rockets all use armor-piercing warheads.

Compared with the fragmentation warheads on helicopters, this type of armor-piercing warhead has stronger penetration ability and will also produce an explosive effect.

When the smoke cleared, a large number of small holes appeared on the skulls of several giant mutant zombies.

At the same time, streams of blood gushed out of it.

It was obvious that the pace of these giant mutant zombies had slowed down, but it did not stop them from moving forward.

After all, shoulder-fired rockets rely on metal jets to penetrate armor.

This metal jet will cool down instantly after encountering flesh and blood, greatly reducing its armor-piercing effect.

"Everyone, take turns to retreat to the second line of defense."

Yang Fan is not the kind of person who would risk the lives of villagers and soldiers to fight against these endless zombies.

Although the village soldiers can be produced in large quantities themselves, Yang Fan does not want to engage in such a war of attrition.

So he planned to temporarily retreat to the second line of defense and rely on the tank guns there to block these giant mutant zombies.

At the same time, Yang Fan was also estimating in his mind where his bomber squadron had arrived.

"I estimate that if we hold out for another two or three hours, the bomber squadron will be able to destroy the islanders' zombie production base."

200 tons of bombs were enough to clear a large area, and Yang Fan had already asked the First Bombing Team to return to the base for reconnaissance to replenish ammunition.

The eight bombers were divided into two groups, with four groups in a shift to carry out bombing in turns.

With such bombing intensity, even if the enemy can repair it quickly, the zombie production factory will be destroyed by the second wave of bombs.

"It depends on whether you can give birth faster or I can explode faster."

This time, Yang Fan invested a huge amount of money. The factory in the rear turned almost all the iron ingots and gunpowder into artillery shells and weapons.

Thanks to the accumulation of supplies in the past few days, Yang Fan has hundreds of millions of iron ingots and gunpowder on hand.

It is more than enough to fight a large-scale world war.

As the villagers and soldiers took turns covering their retreat, the zombies soon arrived under the city wall.

Fortunately, the zombie dogs still arrived first.

With their attack power, they could not break through the obsidian wall.

At the same time, Yang Fan also placed a large amount of TNT during the retreat.

Because the wall is made of obsidian, these TNTs will not damage the main body of the wall.

On the contrary, you can delay the zombies' actions by killing a large number of zombies.

The infantry fighting vehicles carrying the infantry retreated towards the second line of defense.

At the same time, artillery fire was constantly supporting those retreating from the front line.

"Lord City Lord, we have retreated to the second line of defense."

The villagers and soldiers who retreated first have arrived at the second line of defense.

Although it is called the second line of defense, it is still 2 kilometers away from Yangfan’s safe zone.

Behind the second line of defense, villagers are also rushing to build the third line of defense.

At the same time, tanks outside the second line of defense also opened fire one after another.

All tanks use armor-piercing shells, and their main purpose is to deal with giant mutant zombies.

From ordinary mutated zombies to giant mutated zombies, Yang Fan discovered a pattern.

The larger the zombies are, the slower they move.

This may also be caused by their large size, but Yang Fan believes that due to their large size and heavy weight, the movement of these monsters has become inconvenient.

"It seems that the island nation's biotechnology is nothing but breaking through the limits of biology."

A height of 20 meters is already half the size of the largest land creature, the elephant.

In order to support such a huge body, these giant mutant zombies use a multi-group structure.

Even if the tank guns cannot destroy the brains of these giant mutant zombies with one shot, if they can break the multiple limbs they use for movement, they can also restrict their movements.

That's right, these giant mutant zombies use a multi-group structure similar to that of insects.

The giant mutant zombie has a total of 8 legs and moves like a spider.

It's just that the huge head is stretched out to protect the feet on both sides, making it difficult to be hit from the front.

But as long as these giant mutant zombies get close enough, the tanks on the side can interrupt their multiple groups with one shot.

This will greatly limit these huge guys.

"Lord City Lord, the last batch of soldiers have also retreated."

The villagers who had been covering the retreat have basically arrived at the second line of defense.

"Soon, the howitzers began to cover the first line of defense."

The first line of defense cannot be lost in vain. Fortunately, we were using the Obsidian Sword at that time and were not afraid of the bombardment at all.

This is also the reason why Yangfan keeps increasing the number of defense lines.

Once your weapons are unable to deal with some suddenly appearing zombies, you can fight and retreat at the same time, and organize a new defense system on the rear line.

On the one hand, this can increase your tolerance rate, and on the other hand, it can also increase more delay time.

You should know that when facing a defensive battle, the most critical thing that affects the success of the defense is to determine your own defense time.

Yang Fan had roughly estimated in his mind that as long as he could hold on for 24 hours, the entire coast would be completely bombed by bombers.

By then, not even a single bacterium will be able to survive on the coastline.

"There is actually a second line of defense."

Kawashima, who was hiding near the coastline and commanding the battle, was observing the developments on the battlefield through a giant mutant zombie.

As a leader, the zombie not only inherited the wisdom of his previous life as a human, but also because he mutated into a fully commanding zombie, his brain capacity increased and his own strategy also increased.

"It looks like we need to deploy air units."

That’s right, Kawashima still has a trump card.

Although these flying zombies are not numerous and cannot fly for long periods of time or long distances.

But it is more than enough to deal with the current situation.

This is a bat-like zombie that mutated from an ordinary zombie dog.

With huge fleshy wings, they can take off from a standing position, fly to a height of about 30 meters, and then glide.

Through Kawashima's observations, he found that the Dragon people's defense line did not have very powerful anti-aircraft weapons.

As long as 1 to 2 flying zombies land on the city wall, a breakthrough can be created.

Just when he was about to send new zombies to the front line, a whistling sound was heard from the sky.

“Lord Kawashima is a bomber, and the enemy has already dropped the bomb.

The bomber that Yang Fan made using the mobile sky island did not make much noise.

When the flight altitude exceeds 1 km, it cannot even be detected on the ground.

Only when the huge bomb is about to fall to the ground will the buzzing sound caused by friction with the air become noticeable.

Just after the zombie finished reporting to Kawashima, a huge explosion sounded near them.

"The damn Dragon people actually attacked me."

Thanks to the loss of the rescuers around him, Kawashima was not blown away by the shock wave.

His whole body was covered with tumors, and his entire body was a ball of flesh, with a pair of wings growing behind him.

This body structure has no defense at all

Even just one bullet could easily kill him.

But as a commanding zombie, Kawashima will definitely pay attention to this.

Therefore, there are usually many high-level zombies around him to protect his safety.

When the bombs fell, there were already several mutated zombies blocking Kawashima's vicinity. When the first bomb fell, these zombies rushed towards Kawashima and protected him with their bodies.

"All zombie troops, protect the Queen!"

The first thing Kawashima thought of was the queen insects, the zombie production tools.

Once all the queens are eliminated, this landing battle can be considered a failure.

As soon as Kawashima gave the order to protect the Queen Insect, a large number of zombie dogs gathered near the Queen Insect to protect them from the shock wave.

At the same time, some people have entered the underground caves from behind.

The beach that was originally filled with zombies in the other world was now engulfed in a sea of ​​fire.

200 tons of bombs was a lot, but they were all dropped in just a few seconds.

At this time, the beach was filled with huge bomb craters and burning zombie corpses.
