Chapter 551

"Buzz!"

The firepower of the Vulcan cannons can't last all the time. The ones that can shoot for a long time in the movie are just bullshit. If the real firepower is fully opened, the gun barrel will be red in a few seconds at most, and it will be red in less than ten seconds.

Therefore, the fire speed of the Vulcan is generally controlled, and the second is to shoot intermittently.

Automatic fire was also designed with this in mind, so after 15 seconds of continuous fire, it entered the cooling period.

Sun Hongguang also thought about this cooling off period, so he would have this cooling period when he knew that Lu Chuan was used to deal with zombies. Because zombies don't destroy this weapon. When the cooling off period is over, the Pyron will continue to work.

As soon as the shooting stopped, the zombies burst in.

However, they only burst into less than 10 meters, and the second Vulcan opened fire again.

With the data of the first Vulcan, the program in the server will automatically adjust the firing elements of the second Vulcan, which will bring higher shooting accuracy.

The fire of the Vulcan was sweeping towards the head of the zombie.

A zombie's head was hit and then exploded. It's powerful. It's not covered.

Four directions, almost the same trend, zombies have to pay a huge price to be able to make a step forward. They need to be piled up in absolute numbers. Only when the Vulcan is too busy can a few of them break through the fire line of the second Vulcan.

However, some of the breakthrough zombies only ran about 10 meters. With the fire of the second Vulcan, they were harvested like wheat.

Through holographic projection, Lu Chuan holds his arm and observes all this.

"If it's just like this, it's impossible for them to be close to the biochemical factory, not to mention siege."

Although the defense system created by using the resources in hand is not perfect, it seems that the zombies can not break through if they charge like this.

Suddenly, Lu Chuan's eyebrows were wrinkled.

We only see lickers in the holographic projection, climbing on the wall, then bypassing the first cease-fire Vulcan and rushing to the second.

The second Vulcan, which is in the process of crazy shooting, fires downward at the muzzle. It has too many targets. When scanning, it can only adjust and shoot everywhere.

The automatic fire mechanism also has the principle of "rush first and then heavy". However, when the licker approaches, the muzzle of the gun will be adjusted later. Only two or three lickers' heads were smashed. The other lickers had already rushed over and destroyed the Vulcan with their claws.

All kinds of zombies in the streets below crowded without fire suppression.

Unfortunately

The third Vulcan immediately fired, which brought a kind of sour, but also let the sudden zombies want to die and immortal.

This street leads all the way to the biochemical factory, but it's three kilometers long and is covered with automatic fire. Four streets, all the way.

Zombies have to pay a huge price to break through.

Lu Chuan is not very worried about the zombies on the ground. What Lu Chuan worries about is actually the attack from the sky. The most dangerous is the attack in the sky. Once there is a loophole, they dive down and the result is unpredictable.

…………

The number of bloodthirsty claws and corpse dragons gathered in the sky keeps rising, and there are also these two types of flying zombies under the sky. However, when thousands of flying zombies are gathered in the sky, they begin to move.

They're flapping their wings and flying in the direction of the biochemical plant.

They move, is to block out the sun, let people fear.

Lu Chuan knew that it was time to really test his defense lines. As long as they were stopped, this zombie attack was half successful.

With modern resources, the difficulty will not be as difficult as before.

A large number of deployed automatic firepower is actually too ferocious, like gullies that are difficult to cross. The zombies who attack the city need to pay a huge price before they can move forward.

Through holographic projection, the streets are already filled with corpses of zombies. The zombies from the back have to step on the corpses of zombies in front of them to move forward.

"Dong Dong..."

The anti-aircraft gun fired, a shell was shot out, with the help of the computer, the shells accurately exploded at their flying height, and the shrapnel was wantonly sweeping the sky.

A bloodthirsty claw and a corpse dragon were beaten into a sieve.

More than a dozen anti-aircraft guns were fired at the same time. Even in the daytime, the traces of shells could still be seen crossing the sky and then exploding in the bloodthirsty claws.

If you hurt your wings, or if you hurt your bones, you can't support your flight, and fall from the sky.

For example, the bloodthirsty claws and corpse dragons falling down from the rain severely hit the streets and buildings below, and some roofs were even broken.

In fact, the power of more than ten anti-aircraft guns is far beyond Lu Chuan's imagination.In fact, Lu Chuan does not know enough about the performance of anti-aircraft guns. After all, Lu Chuan is not a soldier. How can these anti-aircraft guns be dated back to the 1970s and 1980s? In this era, the anti-aircraft guns have almost played their role to the utmost, and their power is naturally great.

The dense group of flying zombies makes almost every gun fail, which is naturally powerful visually.

But

There are still too many flying zombies, especially bloodthirsty claws. They are very fast and sensitive. They soon fly several kilometers and appear in the air of the biochemical factory.

Lu Chuan stares at them, issued a command: "bloodthirsty claws, snipe at them."

In the last zombie attack, the appearance of corpse dragons almost broke through the defense line and contacted the biochemical factory. Once they get close, their dive will be fatal and it will be difficult to intercept them.

Therefore, Lu Chuan, with experience, will certainly not make this kind of mistake again.

With the instruction of Lu Chuan, the bloodthirsty claws moved, and the scale of 5000 bloodthirsty claws far exceeded them. Of the 5000, Lu Chuan was totally bloodthirsty.

Soon, two groups of dark clouds collided together, both sides tore up.

Fighting, directly into the baizhihua.

Do not know is the other side, or their own bloodthirsty claws, such as the rain continues to fall. From a distance, it looks like a black rain.

Hit the ground, the "bang bang", endless.

In terms of quantity, the 5000 bloodthirsty claws in his hand completely surpass them. In addition, the bloodthirsty claws carry out Lu Chuan's instructions completely. They are desperate to kill each other, and even sometimes they use the same method.

Lu Chuan looks at the situation on the battlefield, not only at the sky, but also at the streets.

For the time being, there is no need to worry about the streets. A large amount of automatic fire ensures that every step forward is difficult for zombies.

With the destruction of lickers, Lu Chuan's automatic firepower is still less and less.

It also means that the crisis is starting to get worse.

…………

In the cracks of time and space, zombies are still breathing.

Zombies are mixed from ordinary zombies to zombies of all levels.

In a very short period of time, the number has exceeded 100000. Leaving aside the large number of zombies killed, at least 80000 or 90000 zombies were divided into several roads and walked along the streets.

A large number of zombies, so that the streets are crowded with zombies, one by one.

With the emergence of the first-time tyrant and the zombies of t-002, it is not difficult to understand the presence of pursuers. If you go up, you'll see a zombie like water ghost, but there's no water here, and the water ghost doesn't appear.

After observing for some time, Lu Chuan found that the zombies were not regular and appeared randomly.

8、 Ninety thousand zombies poured in, forming a wave of four zombies. They almost ignored everything.

In particular, among the 80000 and 90000 zombies, there are still a large number of tyrants of the first trial type. Their size of more than five meters is really too destructive.

In front of them, the concrete fence used for interception is directly kicked to pieces. It is the zombie at the foot of the city. When it is lifted between its feet, it is kicked to fly and kick out a road.
