Global Catastrophe: I Became the World Tree

sudden! sudden! sudden!

Without waiting for these mutated rats to attack, the soldiers of the first brigade were the first to pull the trigger after receiving the order.

Puff puff!

Caught off guard, more than 20 mutant mice were killed in an instant.

The gunfire also instantly awakened these mutated rats. Even if their companions died, they did not show any fear, but instead aroused their ferocity.

As a certain mutant rat took the lead in charging, the remaining 70 or so mutant rats immediately launched an attack.

The physique of mutant mice is much better than those of mutant mosquitoes, mutant flies and mutant cockroaches.

Insecticide poison mist and powerful insecticide water pose no threat to them at all.

Of course, flamethrowers are extremely lethal to any carbon-based creature, and these mutant mice are no exception.

However, what no one expected was that these mutant mice would still rush forward even if their fur was ignited, they squeaked in pain, and even their skin was about to burn and crack.

From this we can see how tenacious these mutant mice are.

Of course, it was impossible for the members of the first brigade to watch them and rush into the defense line.

Gunshots rang out one after another, and some people even fired from the initial burst and then switched to other shooting.

In the end, more than 100 mutant rats were killed before they rushed across the street.

Phew~

Seeing this scene, Chen Dalong couldn't help but secretly breathed a sigh of relief. Not only him, but Feng Jun and Shen Chen beside him also showed expressions of relief.

"I think the method of dealing with mutated rats should be changed. Don't use flamethrowers! With their whole bodies on fire, they will rush into the defense line and pose a greater threat to us." Feng Jun was the first to say.

Although the protective clothing worn by soldiers has good defense, it is not fireproof. If it is ignited, the damage to the soldiers below will only be greater.

"Well, I think so too." Shen Chen nodded immediately.

Chen Dalong listened silently on the sidelines. He was too sensible to interrupt in such matters. After all, he was just a layman in front of such actual combat command. All he had to do now was to read more and learn more.

Soon the new order was conveyed, and the mutant rats arriving later no longer had to endure the torture of the flamethrower.

But their fate is the same. With the firepower of a field automatic rifle, dealing with such a small mutated creature can definitely be called a fierce firepower.

Basically, as long as a bullet can hit these mutated rats, they will either die or be maimed.

Moreover, the first brigade is indeed elite enough, and every soldier has good marksmanship. Even if these mutant rats move very fast, they will basically be killed instantly if they get within 10 meters.

If two or three mutant rats appear in the same location, the soldiers responsible for defense at that location will immediately switch to strafing mode and shoot them away as quickly as possible.

Make sure that no mutant mice can break into the defense line.

Chen Dalong was quite nervous at first, and was ready to rescue at any time.

But what he didn't expect was that for half an hour, he just stood aside and watched, without any need for him to take action.

However, as time goes by.

The number of mutated creatures is increasing rapidly.

At least compared to half an hour ago, the number has more than tripled.

Mutated mosquitoes and mutated cockroaches are okay, as long as the powerful anti-virus water here is not interrupted, no matter how many they come, they will die.

But those mutated cockroaches have more or less affected the soldiers on the front line.

Many times, they have to free their hands to clean up.

Of course, the biggest threat is the mutant rats. In the previous wave, more than 600 mutant rats launched a charge and almost broke into this defense line.

At this time, another large wave of mutated creatures gathered over.

Feng Jun and Shen Chen squinted their eyes and looked at each other, their eyes showing solemnity.

"I estimate there are more than 1,100 mutant mice. Lao Shen, how many do you estimate?" Feng Jun asked.

"It's about the same number as you. I estimate there are more than 1,200 of them. I'm afraid my first team won't be able to stop them." Shen Chen said seriously.

After just over half an hour of fighting, they already had a clearer understanding of the combat power of these mutated creatures.

With the strength of the first brigade, it is estimated that the limit is to resist about 800 mutant rats at the same time. If there are more, some will definitely be missed.

"Well! Then activate the backup plan. My seventh brigade will also defend later, but they still have to deal with mutated cockroaches. There are not many people who can spare their hands. I'm afraid something will go wrong." Feng Jun said, his eyes involuntarily He glanced at Chen Dalong on the side.

"It's okay. If there is any problem, I will take care of it as soon as possible." Chen Dalong immediately expressed his stance.

He had been watching here for half an hour, and his hands were already itchy.

While several people were talking, this group of mutant rats had arrived at West Tai Street and launched a charge.

Chuchuchu!

Intense gunshots rang out, and all members of the First Brigade were in strafing mode, with bullets pouring out like rain.

Even at least half of the members of the 7th Brigade put down their flamethrowers and helped start strafing.

But the second-level mutant mice are even more agile than humans. Coupled with their small size and sense of danger, they subconsciously make evasive movements when running.

In this case, it is not easy for even veterans to hit them, and in the case of strafing, the hit rate is naturally even lower.

"ah!"

A cry of pain came from the defense line not far away.

A soldier's calf was bitten with a bloody hole by a mutated rat that jumped into the defense line.

He quickly pulled out a military dagger and went to chop, but the mutant rat reacted extremely quickly, dodged away with great dexterity, and then bit the soldier's other foot.

Although the soldier escaped the mutant rat's bite, he was unable to continue shooting under such circumstances.

Seeing that the situation was not good, his companions had already turned their firepower over, hoping to help him fend off the mutant rats that followed.

But even so, two more mutant rats got through the fire blockade and rushed into the defense line.

Seeing this scene, both Feng Jun and Shen Chen's expressions changed drastically. If one of them failed to deal with it well, a gap might be torn open in the defense line, and then the mutant rats from behind could drive straight in.

"Don't worry, I'm here." Chen Dalong's voice sounded in their ears.

Before they could answer, they saw a figure leap out and run past at a speed that completely exceeded human limits.
