Global Catastrophe: I Became the World Tree

Boom boom boom!

As soon as Ye Feng came to the city wall, he saw a 30mm self-propelled artillery in front of him, pouring firepower crazily towards the bottom of the city wall.

Ye Feng has learned about this newly developed self-propelled artillery, which can fire at a rate of 1,500 rounds per minute and can cause fatal damage to mutated animals below the fourth level.

It can also automatically lock onto the enemy. If multiple units are loaded together, the computer can form a fire network on its own to conduct coordinated operations.

It can be said that when it was first set up, this thing was positioned as a big killer on the battlefield.

Because most mutated animals are still in the third-level state now, they will have to wait for at least the next spiritual energy recovery before they can break through to the fourth level on a large scale.

And this kind of self-propelled artillery can cause effective damage even when dealing with fourth-level mutant animals.

It can be said that after this new type of self-propelled artillery was developed, huge hopes were placed on it. Now it is basically installed on the walls of every city.

In some key places, such as the military fortress to be built in the Daxinganling Mountains, even more are installed.

But it is a pity that in this war, this new weapon, which had high hopes, failed to exert its due effect.

Ye Feng looked at the self-propelled artillery in front of him, frantically pouring firepower towards a mutated centipede in the distance.

Although the hard shell on the opponent's body was hit with sparks flying everywhere, the damage caused could not be said to be none, it could only be said to be minimal.

The opponent's hard shell was shot for twenty seconds before a hole of about one meter opened. Compared to the opponent's body size of more than ten meters, this could only be regarded as a minor injury.

This mutated centipede, withstanding the fire from a self-propelled artillery, rushed under the city wall and tried to climb up.

However, it failed to succeed. Standing next to the self-propelled artillery, an elite soldier wearing power armor had already noticed it.

At this time, he raised the 2.5-meter-long second-generation Destroyer hand cannon with a caliber of 120 mm.

boom!

With the sound of a cannon, the centipede's head was instantly penetrated by a huge warhead. It only struggled twice and stopped moving.

Seeing this scene, even Ye Feng couldn't help but sigh at the power of this Destroyer hand cannon.

Not to mention these sixth-level mutant insects, even sixth-level mutant animals, unless they have particularly strong defenses, may be killed with one shot.

However, this hand cannon also has many shortcomings.

The first is that the recoil is huge, and you need to wear power armor before it can be used normally.

In addition, after each shot is fired, the shells must be reloaded.

Moreover, these shells are quite large, with a width of 12 cm and a length of 40 cm.

If you are fighting in the wild, let alone loading bullets, just carrying this kind of warhead is a huge trouble.

This kind of defensive battle will be much better, because there are ammunition boxes that can be dragged everywhere. Wherever these soldiers go, they can just drag the ammunition boxes.

Just the reloading time, there is still no way to solve it well.

Even though these powered armors have built-in automatic loading programs to assist, the whole process still takes at least 5 seconds.

In other words, the second-generation Destroyer hand cannon has a maximum rate of fire of only 12 rounds per minute.

In such a battlefield with dense enemies, such a rate of fire is definitely not enough.

But fortunately, the main target of these elites wearing power armor is not these mutant insects, but a smaller number of mutant animals.

At this time, on the battlefield, the main force against mutated insects were ordinary soldiers wearing exoskeleton armor.

What they are equipped with are basically the first generation Destroyer hand cannons.

The power of this first-generation Destroyer hand cannon is much different. It only fires armor-piercing projectiles with a diameter of 70 mm, so the power is naturally one level lower.

Not to mention dealing with sixth-level mutant animals, even fifth-level mutant animals may not be able to be beaten to death.

Of course, if you attack a fifth-level mutant animal, even if you can't kill it, you will definitely be severely injured.

Therefore, the power used to deal with these sixth-level mutant insects with relatively weak defense is barely enough.

Because even if one shot can't kill it, the second shot will definitely kill it.

Of course, the most important thing is that the first generation Destroyer hand cannon is not so bulky and looks like a personal rocket launcher.

And only 70mm bullets are needed, and the size of the bullet is much smaller.

So on this basis, the Scientific Research Department added a magazine to the first-generation Destroyer hand cannon.

Of course, unlike normal magazines, the magazine of this first-generation Destroyer hand cannon is very large. It is more appropriate to say that it is a magazine than a combat backpack.

Although the style of the painting is a bit weird, its effect is real. It can directly increase the attack speed from 12 rounds per minute to 60 rounds per minute.

Therefore, these ordinary soldiers holding the first-generation Destroyer hand cannons are the main force in dealing with mutant insects.

But even if the rate of fire is increased, such fire suppression is still a bit insufficient when facing an endless army of mutated creatures as far as the eye can see.

At least from time to time there would be mutated animals that could break through the blockade and get close to the city wall.

You know, the other side is still in a state of harassment. It is completely conceivable how precarious this section of the city wall will be when they launch a general attack.

Ye Feng walked around and quickly came to the defense line where Chai Shi and other Yangcheng City players were in charge.

Seeing Ye Feng coming, everyone gathered around excitedly.

"Brother Ye, you are finally back. We watched your rescue video and it was really amazing." Chai Shi was the first to say.

The rest of the people were also chattering away, expressing their excitement and admiration.

Contestants like these are actually arrogant at heart, and it is impossible to admire other people under normal circumstances.

But Ye Feng was obviously not in a normal situation.

And Ye Feng can also clearly feel the power of faith gathering towards him from these people.

This brought a smile to Ye Feng's face, and his expression became a little more friendly, "You guys came earlier than me, how do you feel?"

After these people were brought to the evacuation point by Ye Feng, they were almost the first batch to board the transport plane to evacuate. They came back ten minutes earlier than Ye Feng, just in time for the last general attack.

Upon hearing Ye Feng's inquiry, the somewhat excited look on everyone's faces disappeared in an instant, replaced by solemnity.

"It's very pessimistic. There are too many mutant animals. They can easily break through the blockade. We can only rely on us to fight for time in front."

"The last one didn't last long. I felt it was more like someone else's exploratory attack. If they really launch a general attack for a long time at any cost, we players will definitely have casualties. By then, there will be many injured and dead people." , maybe the entire defense line will collapse." Chai Shi said in a low voice.

"There are also those mutated insects, which are also a big trouble." At this time, Lu Tao from the side interjected.

He is a spiritual superpower, and his range of perception is wider and clearer, so he naturally has more information. He also lowered his voice and said: "The mutant insects you see now are actually the ones with not very strong attack capabilities. .”

Hearing this, Ye Feng couldn't help but raise his eyebrows, and Lu Tao continued: "The really troublesome mutant insects are those that can release poison. Even if we, the sixth-level strong ones, are bitten, we will not be able to kill them in time." Even if you clean up the toxins, you will die."

"There are even some mutated insects that can spray their toxins directly. Most of the soldiers killed in battle were caused by these mutated insects."

After hearing these contents, the expression on Ye Feng's face became more serious. He did not expect that the mutant creatures' general attack would be so troublesome.

Of course, he just felt troublesome. He didn't think it was such a difficult problem to solve. As long as the military started executing the bombing plan, it would naturally clear out a large area of ​​mutated creatures, drastically reducing the pressure here.

Thinking of this, Ye Feng was about to say a few words of comfort, but suddenly a harsh alarm sounded from the military camp.

Hearing this voice, everyone's expressions changed slightly.

Lu Tao said immediately: "This is the first level of alert. These mutated creatures are about to launch a general attack again."

At this time, a large number of soldiers were coming out of the military camp towards the city wall. In just one minute, the number of soldiers on the city wall had doubled.

Ye Feng even discovered that not only the regular army, but also the logistics troops were dispatched. They carried large quantities of ammunition and provided logistical support at any time.

While the military was seizing the time to prepare for the war, hordes of mutated animals were approaching in the distance on the horizon.

They were not charging haphazardly, but were arranging their troops in a very orderly manner.

The ones in front are mutant bison, mutant wild boar, and mutant rhino, these animals with rough skin and thick flesh.

Further behind are various predatory animals, which are the main force that climbs the city wall to kill.

Above their heads are various mutated birds, and even these mutated birds are holding one or two tons of boulders in their claws.

Obviously, if they were to fly thousands of meters above the ground and smash these boulders down, the consequences would be absolutely disastrous.

Of course, in front of this mutated animal, there are a large group of mutated insects serving as cannon fodder.

And most of them are mutated insects that can fly, so although these are cannon fodder, they are still a huge threat.

If they leap over the city wall to the rear and kill the logistics personnel, the consequences will be equally serious.

Of course, Ye Feng also saw some mutant insects with particularly bright colors. These should be those mutant insects that can release toxins.

Boom boom boom!

Before the large army of mutated creatures could approach, the artillery battalion started firing violently.

Howitzers and mortars fell into the dense army of mutated creatures one after another, and a large area in front of the city wall turned into a sea of ​​fire.

However, blood splattering did not happen.

These fifth- and sixth-level mutant animals are fully capable of withstanding the damage of these mortars.

Even mutated insects with relatively weak defenses were at best knocked to the ground by the shock wave, but they quickly climbed back up and continued moving forward.

Although they cannot be killed by explosion, these mutated creatures do not mean that they are ineffective.

With their defensive power, they can indeed withstand the shock wave, but when the shells fall directly on them and are in the center of the explosion, they can still cause damage.

And as long as these mutated animals are injured, they will be affected to some extent in the subsequent battle.

It would be better if it could damage their joints or wings, thereby affecting their movement.

It is precisely because of these considerations that the current bombing has occurred.

However, the army of mutated animals advanced very quickly, and soon they were within 2 kilometers of the city wall.

At this time, the soldiers on the city wall all raised their Destroyer hand cannons and started shooting.

Suddenly, the roaring became more intensive, resounding throughout the entire city wall, and the sound was quite loud.

However, the effect achieved was not so satisfactory.

Because the rate of fire of the Destroyer hand cannon is still too slow, and in front of the mutant animal army, there is an army of mutant insects that serve as cannon fodder to resist.

More importantly, these mutated creatures are not targets, they can dodge.

If you can't hit their heads, even with the power of the Destroyer hand cannon, it will be difficult to cause enough damage to kill them.

And is it easy to hit them in the head? Of course it is not easy.

Although the heads of mutant animals are very large, and these soldiers also have auxiliary aiming devices, the probability of hitting the head is only about 50%.

The rate of fire of the Destroyer hand cannon was inherently slow, and the hit rate was not high, which directly led to the army of mutated animals easily breaking through their fire network and arriving under the city wall.

Although this city wall is six stories high, it is nothing to the mutated animals. They can jump directly up with a single leap.

In this case, the contestants stationed at various places on the city wall finally took action.

Flames, water arrows, thunderstorms, hurricanes, and superpowers suddenly appeared all over the city wall.

One after another, the mutated animals that wanted to jump onto the city wall were blasted down again.

The soldiers behind them will also seize the opportunity to open fire.

In this close range situation, their shooting accuracy can be greatly enhanced.

The hit rate can be increased to at least 90%, and the killing efficiency is improved a lot for a while.

But Ye Feng knows very well that if he wants to maintain this situation, these players need to continuously release their powers and engage in such high-intensity confrontation.

When the spiritual energy in their bodies is consumed too much and cannot be sustained, the situation will collapse immediately.

Ye Feng looked at the mutated creatures swarming over the mountains and plains, and even he felt powerless.

In this situation, a person's power is small, even him is no exception.

Even if he can kill 100 mutated animals with one move, there are millions of mutated creatures here, so how can he possibly kill them all.

But even so, Ye Feng still took out the thunder gun from the storage bracelet.

Although he can't rely on his personal ability to resist the mutant creature brigade.

But it can kill those elite sixth-level mutant animals.
