Global Catastrophe: I Became the World Tree

"You guys retreat." Before Chen Dalong arrived, he took the lead and shouted loudly.

The defensive team, which was fighting and retreating at the same time, turned around and ran away without saying a word after hearing the shouting.

The rescue team led by Chen Dalong has taken action more than a dozen times in the past few hours. The teams on the A13 defense line have already seen how powerful they are.

They know very well that staying here is dragging them back, and the retreat can be said to be clean and tidy.

As the defense team retreated, the mutated insects that swarmed up the city wall had no time to disperse and attack other places. Chen Dalong took the lead and rushed into the insect swarm.

The two ring-headed knives in his hands were swung left and right to chop, tease, slash, or sweep, all using the simplest moves.

However, when these moves reach their extreme, their lethality will become extremely terrifying.

In the eyes of others, the two swords in Chen Dalong's hands seemed to form thousands of sword lights. Wherever he passed, the mutated insects were cut in half.

As Chen Dalong entered the scene, most of the mutated insects immediately attracted the attention and launched an attack on him.

At this time, the remaining members of the rescue team entered the scene one after another.

With Chen Dalong in front, their pressure is undoubtedly much less, but even so, they simply don't dare to run rampant like Chen Dalong.

After all, each of these mutated insects that can rush to the city wall can be regarded as the best of its kind. As long as they are careless, they may be injured.

Therefore, among the nine people following behind, four of them were good at melee combat and were holding cold weapons in front.

Their mission is to create a safe output environment for their companions behind them.

The five people being protected at the back are all veterans with superb marksmanship. After becoming Evolvers, their strength, vision, and reaction speed have been greatly enhanced.

Da da da!

All five of them were using the strafing mode. If it were before, even if the strafing mode was used within 10 meters, the hit rate of the bullets would not exceed 20%.

After all, in the strafing mode, 10 bullets will be fired in one second. A normal person will not even have time to move the muzzle of the gun, and a shuttle of bullets will be shot out.

Under this situation, a 20% hit rate is already the result of their years of training.

But now that he has become an Evolver, his marksmanship has been greatly enhanced. When shooting these mutated insects, as long as the distance does not exceed 10 meters, the effective hit rate of the bullets can even reach half.

This doesn't sound like much, but it's actually pretty scary.

An automatic rifle has 30 rounds of bullets in one magazine. In strafing mode, it can be fired in three seconds. The effective hit rate is 50%, which means that about 15 mutant insects can be killed in three seconds.

With the five of them shooting alternately, their efficiency in killing mutated insects was only faster than Chen Dalong's.

In just one minute, with the combined efforts of everyone, more than half of the more than 300 mutated insects that rushed up this section of the city wall were killed.

However, as the number of mutated insects decreases and they are no longer so dense, the killing efficiency naturally begins to decline.

All the members changed from strafing mode to burst shooting mode. Chen Dalong also changed from being chased by mutated insects to chasing mutated insects.

After another nearly 4 minutes, everyone finally killed the last mutated insect on this section of the city wall.

"Is anyone injured?" Chen Dalong put away his swords and came over to ask.

"No." Everyone said in unison.

No one was injured, which is naturally good news, but Chen Dalong is not happy at all now.

He glanced at the swarm of mutated insects in the distance, which seemed to be getting denser and denser, and sighed and said: "Then everyone hurry up and replenish the ammunition. I guess it won't take long, the next wave of attacks is coming."

The others also had solemn expressions after hearing this.

They all felt that this attack was unusual, and they had a bad feeling in their hearts.

Just five minutes later, their hunch came true.

Another large wave of mutated insects is coming.

…

At the same time, Bai Yinghui on another section of the city wall frowned as he looked at the mutant insect swarm that was attacking again.

"The attack frequency has really been strengthened, and it has been tripled. What do you think of the analysis results from your staff department?" Bai Yinghui asked the chief of staff, Jian Yan.

"After discussion with our staff, we believe that the sound of gunfire here has attracted a certain amount of mutant insect swarms, and their movement speed has accelerated."

"Originally, we were only fighting the vanguard, but with the arrival of more and more mutated insects, it is very likely to directly evolve into a decisive battle." Jian Yi said with a wry smile.

Bai Yinghui:? ? ?

He looked at Jian Yi, the chief of staff, with sharp eyes and said, "According to your staff's prediction, the insect swarm will launch a general attack probably on the third day after the war begins."

"It's only been a few hours now, and you're telling me that we're going to have a decisive battle? How did you predict it before? Are you just doing it for a living?"

Jian Yi murmured for a moment and then said: "There is indeed a big problem with our prediction this time, and I am willing to take the responsibility this time..."

"Stop! Don't tell me those useless things." Bai Yinghui waved his hand to interrupt the other person's words and said, "Tell me first, what suggestions do you have in face of this situation?"

"First, to implement the decapitation plan, we have targeted the more special mutant insects mixed in the mutant insect swarm. They should be the commanders."

"Before the decisive battle, we can use Reaper missiles to eliminate them in one go, which may cause chaos in the insect swarm. Of course, the insect swarm is different from humans. It is only a guess whether the insect swarm will be effective."

"Second, the troop training plan is about to end early. I suggest that we directly use the means we have prepared before to kill the mutant insect swarms as much as possible before their general attack, while preserving our combat power." Jian Yi said.

Bai Yinghui nodded after hearing this. He thought for a moment and asked, "How are the casualties now?"

"In the past four hours, the number of injured people has reached 7,236. Among them, 6,404 people were slightly injured and could return to the battlefield after being bandaged. 832 people were seriously injured and could not continue to fight. In addition, 132 people died in the battle." Jian Yi replied immediately. .

Bai Yinghui frowned slightly after hearing this. This number was much higher than they originally expected.

The number of people seriously injured and killed was as high as 964, which was already close to 1,000.

This has only been a 4-hour battle, and what they faced before was the vanguard. If they really faced the main force of the insect swarm, this number would probably increase several times.

And even though the 6,404 lightly wounded soldiers can return to the battlefield after being bandaged, it does not mean that their combat power will be restored immediately. It is good to retain two-thirds.

Thinking of this, Bai Yinghui ordered: "Activate the metal storm on the city wall and distribute the new equipment we developed."

"Finally, let the bombardment team prepare. If those mutated insects dare to gather in one place to attack, then I will blow them up hard."

Jian Jian nodded immediately and sent the order back to the staff for them to execute.

After a moment, he asked: "Does the number of people defending the city wall need to be increased?"

Their military, major security companies, and corporate combatants totaled up to 60,000 people.

With so many people, it is naturally impossible to send them all to the city wall to defend. In fact, they have always maintained their manpower at around 30,000.

The remaining people will take turns to rest. After all, in this kind of high-intensity battle, they are not steel, so rest is inevitable.

Bai Yinghui thought for a moment and shook his head, "We will take a look at the casualties later. As long as they are within the tolerable range, then do not increase the manpower."

"After all, the vast majority of the troops are new recruits, and we need to give them some time to adjust themselves."

As new orders are issued one after another, the trend of the next battle is also undergoing huge changes.

First, the artillery team entered the scene. Although the soldiers on the city wall also had grenades before, how could the power of grenades be compared to mortars.

Of course, more importantly, the efficiency of ammunition delivery.

After the mutated insects rushed through the flame zone, they were only 20 meters away from the city wall, so the window period left for them to bomb was only a dozen seconds.

In this case, the number of grenades that each person can throw is quite limited.

But if you switch to the artillery squad, it will be different.

They have specially modified artillery launchers that can load hundreds of mortars at one time and launch them in one go.

In this case, not to mention just a few thousand mutated insects gathered together, even if the number doubled or tripled, they could all be taken away in one wave.

So when the bombardment team entered the scene, the mutant insect's previous tactics of point-pointing Arrancar went bankrupt.

He didn't even dare to do so later, when more than 1,000 mutated insects gathered in one place.

As these mutated insects dispersed throughout the city wall to launch attacks, the metal storm on the city wall also started.

The so-called metal storm is actually a machine gun embedded in the wall.

These machine guns were installed in the foundation when the city wall was built. After being activated, a small hole would be exposed under the city wall, which is the position of the muzzle, and then it would fire in a fan shape.

Because these machine guns were placed at the foundation of the city wall, the muzzles were almost level with the ground.

Under this situation, as long as the mutant insects are densely packed to a certain extent, even if no one is aiming, just follow the set procedure and shoot in a fan shape, there is still a high probability of hitting those mutant insects.

And when the metal storm is activated, the effect is very significant.

The number of mutated insects killed by the metal storm was no less than that of the soldiers on the city wall.

The only problem is that it consumes a lot of bullets, more than 10 times that of a soldier.

Therefore, the metal storm will only be activated when the attack of the mutant insect swarm reaches a certain level.

As for the last arrangement, it is to replace the equipment of these soldiers.

There are two new types of equipment. The first is the powerful shotgun.

The scariest thing about mutated insects is their numbers, but their defense is mediocre, not even comparable to first-level mutated animals.

So even a shotgun that is not very powerful can kill them instantly as long as it hits.

Moreover, this thing has basically no requirements for marksmanship. It is undoubtedly the most suitable for new recruits. As long as it is aimed at a place with many mutated insects, it can kill at least a dozen of them with one shot.

With the shotgun, the efficiency of these soldiers on the city wall in killing mutated insects has increased by at least three times.

Shotguns are offensive weapons, and among the newly equipped weapons, defensive weapons are naturally indispensable.

That's the shield.

Yes, every defensive team received at least two giant shields.

Compared with other shields, this kind of shield is very different in shape. First of all, it is not vertical, but horizontal.

The width is 1.5 meters, but the height is only 1 meter. This is completely designed for mutant insects.

In addition, this kind of shield is quite light because it is hollow inside, and the only thing really used for defense is the three-millimeter-thick steel plate on the front.

On the one hand, this design is for flexibility and is very convenient for movement, and the three-millimeter-thick steel plate can also block 99% of mutant insect attacks.

On the other hand, this hollow shield contains a mystery and has a powerful discharge device.

As long as the switch is triggered, the surface of the shield can instantly release high-voltage current, allowing this defensive shield to also be used as a powerful offensive weapon.

As these back-ups were activated one by one, the situation on the battlefield was instantly reversed.

The soldiers on the city wall became more comfortable when faced with the mutant insect swarm again, and the number of casualties also dropped rapidly, at most only one-tenth of the previous number.

But even though the situation in front of them is great, not many people are really excited, especially the top military officials.

Although their combat power has increased, so has the mutant insect swarm.

Almost every hour, the attack intensity of the mutant insect swarm will increase to a higher level.

No one knows how long their advantage can be maintained.

Time passed little by little, and finally one night passed.

When the time came to 6:30 in the morning, a touch of fish belly white had already risen in the distance.

As the morning light shone, the soldiers on the city wall did not survive the night of joy.

Because as the sunlight drive drove away the darkness, they could see farther away, and the mountains and fields were full of mutated insects.

That terrifying amount can definitely make people suffer from trypophobia.

And the huge insect swarm, like dark green sea water, is slowly but surely approaching Yangcheng City.

That's an army of mutated insects.

Seeing the scene in front of him, let alone these ordinary soldiers, even Ye Feng felt a little numb.

Under normal circumstances, it would be difficult to kill such a large number of mutated insects even if they came out from the Dragon King Palace. It is more likely that they would be slowly consumed to death.

Ye Feng felt that this time he might really have to take action to solve the problem.

While thinking about this, he looked at Bai Yinghui in the distance, but was a little surprised to find that the other person had a calm face.

"Eh! Could it be that the military is sure to deal with it?"
