Global Cataclysm: I became a 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, the rate of fire can reach 1500 rounds per minute, and it can cause fatal damage to mutant animals below the fourth level.

Moreover, it can automatically lock the enemy. If multiple units are loaded together, the computer can also form a firepower network by itself for joint operations.

It can be said that at the beginning of the setting, this thing is positioned as a big killer on the battlefield.

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

And this kind of self-propelled artillery can cause effective damage even against fourth-order mutated animals.

It can be said that after this new type of self-propelled artillery was developed, it was placed with great expectations, and now it is basically installed on the walls of every city.

Some key places, such as the military fortress that will be built in Daxing'an Mountains, have more installations.

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

Ye Feng looked at the self-propelled artillery in front of him, and frantically poured firepower at a mutant centipede in the distance.

Although the hard shell on the opponent's body was hit with sparks flying everywhere, the damage caused cannot be said to be non-existent, it can only be said to be negligible.

The opponent's hard shell was shot for 20 seconds before it cracked a hole of about one meter. Compared with the opponent's body size of more than ten meters, this can only be regarded as a minor injury.

This mutated centipede rushed to the bottom of the city wall under the fire of a self-propelled artillery, trying to climb up.

However, it failed. Standing beside the self-propelled artillery, an elite soldier in power armor had already noticed it.

At this time, he raised the second-generation Destroyer hand cannon in his hand, which was 2.5 meters long and had a caliber of 120 mm.

boom!
With the sound of a cannon, the centipede's head was instantly pierced by a huge bullet, and it stopped moving after only two struggles.

Seeing this scene, even Ye Feng couldn't help feeling the great power of this Destroyer hand cannon.

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

However, this hand cannon also has many disadvantages.

First of all, the recoil is huge, and power armor needs to be worn before it can be used normally.

In addition, after each shot, 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, not to mention 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 drag the ammunition boxes to wherever they go.

It's just the reload time, and there is still no way to solve it well.

Even if these power armors have a built-in automatic loading program to assist, the whole process will take 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 densely populated battlefield, such a rate of fire is definitely not enough.

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

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

What they are equipped with is basically the first-generation Destroyer hand cannon.

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

Don't talk about dealing with sixth-order mutated animals, even fifth-order mutated animals may not be able to kill them.

Of course, attacking a level five mutated animal, even if it couldn't be killed, would definitely cause it to be severely injured.

So to deal with these sixth-order mutated insects with relatively weak defenses, the power is barely enough.

Because even if the first shot can't kill it, the second shot will definitely be able to kill it.

Of course, the most important thing is that the first-generation Destroyer hand cannon is not so bulky, it just looks like an individual bazooka.

Moreover, only 70mm bullets are needed, and the volume of the bullets is quite small.

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

Therefore, these ordinary soldiers holding the first-generation Destroyer hand cannon are the main force to deal with the mutated insects.

But even with the increased rate of fire, facing the army of mutated creatures that can't be seen at a glance, such firepower suppression is still not enough.

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

You must know that the opponent is still in a state of harassment. It is entirely conceivable how precarious this section of the city wall will be when they launch a general attack.

Ye Feng took a look around, and soon came to the defense line that Chai Shi and other Yangcheng players were in charge of.

Seeing Ye Feng coming, everyone surrounded him excitedly.

"Brother Ye, you are finally back. We watched the rescue video behind you. It is really amazing." Chai Shi was the first to say.

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

Contestants like these are actually arrogant in their hearts, and it is impossible to worship other people under normal circumstances.

But Ye Feng is obviously not in a normal situation.

And Ye Feng could clearly feel the power of faith coming towards him from these people.

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

After these people were taken 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.

Hearing Ye Feng's question, the excited look on everyone's faces disappeared in an instant, replaced by solemnity.

"It's not optimistic. There are too many mutated animals. They can easily break through the blockade. We can only rely on us to buy time in front."

"The last time it lasted was not long. I feel more like someone else's tentative attack. If they really launch a general attack for a long time at any cost, we players will definitely suffer casualties. By then, there will be more injuries and deaths. , the entire line of defense may be about to 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 who was on the side interjected.

He is a psychic supernatural being, with a wider and clearer range of perception, and naturally he has more information. He also lowered his voice and said: "The mutated insects you see now are actually the kind that don't have strong attack capabilities. .”

Hearing this, Ye Feng couldn't help raising his eyebrows, and Lu Tao continued: "The really troublesome mutated insects are those that can release extremely poisonous. Even if we, the sixth-level powerhouses, are bitten, if we are not timely Clean up the toxins, but also die."

"There are even toxins from some mutated insects that can be sprayed out directly. Most of the deaths of soldiers are caused by these mutated insects."

Hearing these contents, Ye Feng's expression became more serious, and he never thought that the general attack of mutant creatures would be so troublesome.

Of course, he just felt troublesome, and didn't feel how difficult it was to solve. As long as the military started to carry out the bombing plan, it would naturally clear out a large area of ​​mutant creatures, reducing the pressure here sharply.

Thinking of this, Ye Feng just wanted to say a few words of comfort, but suddenly there was a harsh siren from the barracks.

Hearing this voice, everyone's expressions changed slightly.

Lu Tao immediately said: "This is a first-level alert, and these mutated creatures are about to launch a general attack again."

At this time, a large number of soldiers came out of the barracks towards the city wall. In just one minute, the number of soldiers on the city wall had doubled.

Even Ye Feng found that not only the regular army, but also the logistics soldiers were dispatched. They carried a large number of ammunition and provided logistical support at any time.

When the military seized the time to prepare for the battle, there were groups of mutated animals approaching in the distance of the horizon.

They are not charging indiscriminately, but rather methodically forming formations.

In the front are the mutated bison, mutated wild boar, and mutated rhinoceros, these animals with rough skin and thick flesh.

After that, there are all kinds of predators, and they are the main force on the city wall to kill.

On the top of their heads, there are all kinds of mutated birds, and even these mutated birds are holding one or two tons of boulders in their claws.

Obviously, if they were flown to a height of thousands of meters above the average and smashed down these boulders, the consequences would be unimaginable.

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

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

If they jumped over the city wall to the rear and killed the logistics personnel, the consequences would be extremely serious.

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

Boom boom boom!
Before the army of mutant creatures approached, the artillery battalion started firing violently.

One after another howitzers and mortars fell into the dense army of mutant creatures, and a large area in front of the city wall became a sea of ​​flames.

However, the blood spattering did not happen.

These fifth- and sixth-order mutated animals are completely capable of withstanding the damage of these mortars.

Even the mutated insects with relatively weak defenses were at most only knocked to the ground by the shock wave, but quickly climbed up again and continued to move forward.

Even though they couldn't be killed, these mutated creatures didn't mean they had no effect.

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

And as long as these mutated animals are injured, they will be more or less affected in the ensuing battle.

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

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

However, the army of mutated animals advanced very fast, and it didn't take long to get close to the city wall within 2 kilometers.

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

Immediately, more intensive roars resounded through the entire city wall, and the momentum was quite huge.

It's just that the effect played is not so satisfactory.

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

More importantly, these mutated creatures were not targets, they would 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 want to hit their heads, is it easy?Nature is not easy.

Although the mutated animals have big heads, and these soldiers also have auxiliary aiming equipment, the probability of hitting the head is only about 50%.

The rate of fire of the Destroyer hand cannon was slow, and the hit rate was not high, which directly led to the army of mutated animals, which easily broke through their firepower net and came under the city wall.

Although this city wall is as high as a 6-story building, it is nothing to mutant animals. They can jump up directly with a single vertical leap.

Under such circumstances, the contestants stationed everywhere on the city wall finally took action.

Flames, water arrows, thunderstorms, hurricanes, all of a sudden, supernatural powers appeared everywhere on the city wall.

The mutated animals that wanted to jump up the city wall were bombarded down one after another.

And the soldiers behind them will seize the time 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 has improved a lot for a while.

But Ye Feng is very clear that to maintain this situation, these players need to constantly release their abilities and engage in such high-intensity confrontations.

When the spiritual energy in their bodies is consumed too much and they can't support it, this situation will collapse immediately.

Ye Feng looked at the mutated creatures flooding all over the mountains, even he felt powerless.

In this situation, the strength of a person is small, even he is no exception.

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

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

Although he couldn't rely on his personal ability to resist the mutated creature brigade.

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