Global Catastrophe: I Became the World Tree

At this time, Bai Yinghui and a group of generals also arrived on the northern city wall.

When they saw that the powerful insecticidal water failed to kill any mutated insects, although they had expected it, their hearts still sank.

"How much reserve do we have of the second-generation powerful insecticidal water?" Bai Yinghui couldn't help but asked the chief of staff beside him.

"The production process of the second-generation powerful insecticidal water is too complicated, and it also requires a lot of mutated plants containing toxins as raw materials, so we only made about 200 kilograms of it in a hurry and can only use it in key places." Simple He said with a sigh.

"Based on the resistance of these mutated insects to insecticidal water, based on your estimate, how many mutated insects can be killed by 200 pounds of second-generation powerful insecticidal water?" Bai Yinghui asked with a frown.

"According to the deduction from the staff department, the maximum number is no more than 2 million." Jian Jian replied.

Bai Yinghui couldn't help but sigh secretly after hearing this. The Chinese Academy of Sciences has been developing the second generation insecticidal water for a long time.

But because the production process is too complex, it has been perfected.

When the third spiritual energy revived and large-scale second-order mutated insects appeared, the Chinese Academy of Sciences also knew that it could not wait any longer and had no choice but to make public the unfinished method of making the second-generation powerful insecticidal water.

After Yangcheng City got the formula, Bai Yinghui immediately ordered it to be made, but unfortunately it took ten days to come up with just this little.

Moreover, not only is the production process of this product complicated, but the cost is also a bit high. Basically, one kilogram of the second-generation powerful insecticidal water requires a full 100,000 Chinese coins.

In the current situation of tight funds, he simply does not dare to mass-produce.

"Then pass the order and distribute the second generation powerful insecticidal water to each rescue team. I hope they can exert their due effect." After Bai Yinghui said to Jian Hua, his attention returned to the battlefield in front of him again. .

At this time, those at the forefront of the mutated insect army had passed through the coverage area of ​​the powerful insecticidal water and were about to approach within 50 meters of the city wall.

On the city wall, soldiers holding flamethrowers were already waiting. When these mutated insects entered the 50-meter flamethrowing range, they did not hesitate to pull the trigger.

In an instant, long tongues of flame shot out from the nozzle, covering the army of mutated insects that were advancing below.

And this time not only flamethrowers were used, but incendiary bottles filled with kerosene were also thrown down by the soldiers above. Almost instantly, the area below the city wall turned into a sea of ​​fire.

The mutant insect that rushed forward was swallowed up by the sea of ​​fire almost instantly.

Even if these mutated insects have reached the second level, some mutated insects with strong defense are even more difficult to be harmed by swords.

However, they are carbon-based life forms after all. Under the burning of the flames, even the toughest shells are quickly becoming charred, twisted, and cracked, and their life breath is also weakening at an extremely fast speed.

However, these mutated insects will not sit still and wait to be burned alive.

Some of them were moving quickly, trying to rush through the sea of ​​fire as quickly as possible and rush to the city wall.

But most of them are rolling around on the ground based on animal instinct, trying to extinguish the flames on their bodies.

Under normal circumstances, if they were exposed to fire oil, it would be unrealistic to rely on rolling to extinguish the flames.

But the problem is, outside the city wall is the wilderness. These are second-order mutant insects. Even if they are only the size of a fist, they can explode with dozens of kilograms of power.

As they rolled desperately, and even burrowed into the ground, sand and gravel flew everywhere, and mud filled the sky.

The silt covering the body actually quickly extinguished the flames on the body.

And not only that, as they turned over the soil, the sea of ​​​​fire that was still burning was also extinguished at a speed visible to the naked eye.

The unexpected scene in front of him made Bai Yinghui twitch the corner of his mouth and his face gradually turned ugly.

Because this not only means that they need to consume more fuel to maintain this sea of ​​​​fire, but the power will also be reduced a lot.

"Damn it! Why didn't we think of this before? If we had known, we would have covered this area with cement to see how they could drill." Bai Yinghui gritted his teeth and said.

Jian Yi was silent on the side. How big of a project is this?

Even if they knew it in advance, they probably wouldn't do it. Wouldn't it be nice to raise the city wall another two to three meters?

More importantly, as the soldiers reacted and threw more Molotov cocktails, the sea of ​​​​fire could still be maintained.

However, the power reduction is inevitable, and with the previous mutant insects as examples, the mutant insects that come later will burrow into the ground. Basically, they will choose to burrow into the ground, and the effect they can achieve will be even lower.

But even so, nearly one-third of the mutated insects were directly burned to death when passing through this sea of ​​fire.

And even if they were not burned to death on the spot, they were first eroded by the toxins of powerful insecticide water and then burned. Their physical condition has declined greatly, and it is difficult to say whether they are even half of what they were before.

However, they still failed to attack the city wall because there was still one last hurdle.

When these mutated insects approached 10 meters away from the city wall, grenades were thrown from the city wall.

Boom boom boom boom!

Intensive roars sounded one after another.

Each grenade can kill a large area of ​​mutated insects.

After all the insecticide spraying, flame burning, and the last round of grenade bombing, the number of mutated insects that finally came to the city wall was only 30% of the original number at most.

Moreover, their combat effectiveness has been weakened by half.

This is the benefit of fighting positional warfare. Only positional warfare can fully utilize human weapons.

After the mutated insects reach the city wall, they are not able to attack.

They also have to climb up this wall, which is 5 meters high.

When the city wall was built, in order to prevent these mutated insects from climbing, the outer wall was not only vertical, but also quite smooth. At least there were no gaps on the surface of the wall for climbing.

However, these mutated insects are indeed amazing. As their legs or claws mutate, they will become very sharp and can actually be inserted directly into the cement-filled wall.

Although their sharp claws can only penetrate about a millimeter or two into the wall, it is enough to support the weight of their bodies and climb up quickly.

But how could the soldiers above just watch them climb up? They immediately raised their guns, took aim, and then pulled the triggers.

Chuchuchu!

In an instant, the barrage of bullets swept downwards.

Especially above the city wall, machine guns were placed every 5 meters, and the firepower was even more fierce at this time.

It is worth mentioning that the bases of these machine guns are specially set up. The people above can push the machine guns out directly, and then point the muzzle downward at a 90-degree vertical position, specifically for shooting climbing mutant insects. .

Under the ferocious firepower, the climbing mutant insects suddenly fell like raindrops.

These mutated insects, even beetles with relatively strong defenses, cannot withstand the attack of bullets, and will be penetrated and killed in an instant.

Seeing this scene, Ye Feng couldn't help but sigh. If the military had time to prepare more than ten days ago, the mutant biological crisis would not have had much impact at all.

"However, there are many types of insects in this mutated biological crisis. It is probably impossible to completely resist it with this method alone." Ye Feng murmured softly.

Not long after he finished speaking, he saw three mutant stick insects climbing very fast on a section of the city wall more than 300 meters away from him.

The 5-meter city wall is actually not very high. For these mutated insects, it takes more than ten seconds to climb up, and it takes seven or eight seconds to climb up quickly.

The three mutant stick insects that Ye Feng observed seemed to be much stronger than the same kind. It took them just three seconds to climb the 5-meter city wall.

He immediately launched an attack on the nearest soldier.

Those attacked by them were all new recruits. They were obviously a little panicked at this time. They quickly drew out their machetes and attacked the mutated stick insects.

But after passing many difficulties and reaching the city wall, these three mutant stick insects were not so easy to deal with.

Except for one soldier who hit the stick insect, the other two soldiers' attacks failed, and they also suffered counterattacks from the mutated stick insect. A long gash was opened in their combat uniforms in an instant. .

If it hadn't been for the nearest veteran who came to help immediately, I'm afraid the two recruits would have suffered serious trauma from defeating the mutated stick insect.

Although the three mutant stick insects were successfully solved in the end, it still took more than ten seconds.

At this time, more mutated insects had already climbed up.

However, the military had already anticipated this situation. A battalion commander in charge of this section of the front immediately asked the reserve team to go up and suppress the fire, so no major problems occurred.

However, there is more than one place where this kind of thing happens.

Ye Feng looked to the other side, where there were two mutated scarabs coming to the bottom of the city wall.

They didn't need to climb at all, they directly opened the wings hidden under the carapace, and flew upwards quickly after flapping.

And further away, there is a group of mutated crickets. They don't need to climb the city wall. With their powerful hind legs, they kick the ground and jump over a height of 5 meters to reach the top of the city wall.

Suddenly, many places in this section of the city wall were attacked by mutated insects.

Although such an attack was quickly resolved, it also left a haze in everyone's mind.

Because facing these second-level mutated insects, ordinary soldiers really don't have much advantage in terms of physical fitness. Even if they don't have weapons and protective clothing, it's hard to say whether they can win a one-on-one fight.

Ye Feng watched for a while on the city wall and saw that the military did not use any more methods. He also understood that the other party was probably training troops. If there were no accidents, it would probably remain in this state for the time being, so he closed his eyes and rested. got up.

Of course, Ye Feng had actually switched the possessed state to his body, and then took out his mobile phone to check the news online.

The third-level mutated creatures under him were all invited to sit there. In the wartime state, it was not convenient for Ye Feng to possess them and fly around at will.

In this case, you can get more and more comprehensive information by using your mobile phone to surf the Internet.

When Ye Feng opened the software, all kinds of information popped up without him having to check it. Many of them were short videos taken by the residents themselves, especially those near the city wall.

From their words, there was more or less a hint of panic.

In addition, there are also some bold anchors who have selected some high-rise buildings early, set up video equipment that can shoot from a distance, and started live broadcasting.

Of course, if there is any live broadcast room with the largest number of people, it is undoubtedly the live broadcast room of Du Gulan, a frontline reporter.

Ye Feng couldn't help but click in and take a look.

At this time, Du Gulan was standing on the city wall with a photography team. At this time, her pretty face was a little pale, and she seemed to be frightened.

Although she was facing the camera, her eyes would drift to the outer wall from time to time, and she said quickly: "In order not to affect the soldiers fighting here, the live broadcast on the city wall will be here. Next, we will follow the original plan, Go and interview the leader in charge of this section of the city wall."

After she finished speaking, she immediately walked down the stairs.

Ye Feng glanced at the barrage.

Home No. 2: "Whether it's okay to go down, it was too dangerous just now. She was standing so far away, but the mutated damselfly came directly towards her. I was shocked even through the screen."

Joy in this life: "It is said that after biological mutations, the wisdom will become higher and higher. Maybe the mutated damselfly, you can see at a glance that she is the weakest, just find a soft persimmon to pinch! [Dog Head]"

Shangshan Ruoshui: "Isn't anyone concerned about the situation? The live broadcast has only been live for ten minutes. I just counted that there are nearly 20 people injured on this section of the city wall. The number of casualties on the entire city wall is absolutely terrifying." "

Everyone in the live broadcast room was talking about it, but suddenly, the barrage became uniform, and they all used Chen Dalong's name.

The staff also discovered this and immediately reminded Du Gulan.

"Chen Dalong? Why did you mention him all of a sudden?" Du Gulan had some confusion on his face.

After being reminded by everyone in the live broadcast room, he soon saw Chen Dalong sharpening a knife under a military tent in the distance.

Du Gulan's eyes suddenly lit up, and he turned towards the camera and said: "I didn't expect that by such a coincidence, I saw the strongest man in our Yangcheng City. Let's go over now to interview Mr. Chen Dalong and ask him what he thinks about the current situation."
