Suddenly! Suddenly! Suddenly!

Without waiting for these mutant rats to attack, these soldiers of the first brigade took the lead in pulling the trigger after receiving the order.

Puff puff!

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

And the sound of gunfire also instantly woke up these mutant rats, even if their companions died, they did not have any fear, but also aroused ferocity.

As a certain mutant mouse took the lead in the charge, the remaining more than 70 mutant rats immediately launched an attack.

The physique of mutant rats is much better than that of mutant mosquitoes, mutant flies and mutant cockroaches.

Insecticidal poisonous mist and powerful insecticidal water pose no threat to them at all.

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

However, what everyone didn't expect was that even if the fur on these mutant rats was ignited, they squeaked in pain, and even their skin was about to burn and crack, they would still rush forward.

From this point, you can see how tenacious the vitality of these mutant rats is.

Of course, the members of the First Brigade naturally couldn't watch them rush into the defensive line.

Gunfire rang out one after another, and some people even fired from the very beginning, and then changed to other strafing at the back.

Eventually, before they could cross the street, they killed all 100 mutant rats.

Call~

Seeing this scene, Chen Dalong couldn't help but secretly breathe a sigh of relief, not only him, but also Feng Jun and Shen Chen beside him, who also showed a relieved expression.

"I think the way to deal with mutant rats should be changed, don't use flamethrowers! They are on fire all over their bodies, and when they rush into the defensive line, they will pose a greater threat to us. Feng Jun was the first to speak.

The protective clothing worn by the soldiers, although the defense is good, is not fireproof, and if it is ignited, the damage caused to the soldiers below will only be greater.

"Well, that's what I thought, too." Shen Chen nodded immediately.

Chen Dalong listened silently on the side, he didn't intervene in this kind of thing, after all, in front of this kind of actual combat command, he is just a layman, and what he has to do now is to watch more and learn more.

Soon a new order was delivered, and the mutant rats that arrived later no longer had to endure the torment of flamethrowers.

But their fate is the same, with the firepower of a field automatic rifle, against this small mutated creature, it can definitely be called ferocious.

Basically, as long as the bullet can hit the body of these mutant rats, they are either dead or maimed.

And the first brigade is indeed elite enough, each soldier's marksmanship is good, even if these mutant rats move fast, but if they get close to a distance of 10 meters, they will basically be killed instantly.

If two or three mutant rats appear in the same location, the soldier in charge of defense at that location will immediately switch to strafing mode and pop them out as quickly as possible.

Make sure that no mutated rats are able to break into the defenses.

At first, Chen Dalong was still quite nervous, and he was ready to rescue everywhere at any time.

But what he didn't expect was that for half an hour, he just stood aside and watched, and he didn't need to make a move at all.

Over time, though.

The number of mutated creatures is increasing rapidly.

At least that's more than three times more than half an hour ago.

Mutant mosquitoes and mutant cockroaches are okay to say, as long as the powerful anti-virus water on their side is not interrupted, no matter how many come, they will be sent to death.

But those mutant cockroaches, more or less, will affect the soldiers on the front.

A lot of the time, they have to free up their hands to clean up.

Of course, the biggest threat is the mutant rats, just in the previous wave, more than 600 mutant rats launched a charge, almost rushing into this line of defense.

At this time, a large wave of mutated creatures gathered.

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

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

"It's not far from you, I estimate that there are more than 1,200 of them, and my first brigade may not be able to stop it." Shen Chen said with a serious expression.

After just more than half an hour of fighting, they already had a relatively clear understanding of the combat power of these mutated creatures.

With the strength of the first brigade, it is estimated that at the same time, resisting about 800 mutant rats is the limit, and if there are more, there will definitely be misses.

"Hmmm! Then activate the backup plan, and my seventh brigade will also follow the defense later, but they also have to deal with mutant cockroaches, and there are not many people who can free their hands, and I am afraid that something will go wrong. Feng Jun said, his eyes involuntarily aimed at Chen Dalong on the side.

"It's okay, if something goes wrong, I'll take it as soon as possible." Chen Dalong immediately said.

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

While a few people were talking, the mutant rats had arrived at West Tai Street and then launched a charge.

Sudden Sudden Rush!

Dense gunfire rang out, and the members of the first brigade had already switched to strafing mode, and bullets rained down.

Even at least half of the members of the Seventh Brigade lowered their flamethrowers and helped start strafing.

However, second-order mutant rats are even more agile than humans, coupled with their small size and the perception of danger, they subconsciously make dodge actions when they run.

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

"Ahh

Not far away, a cry of pain came from the defensive line.

A soldier's calf was bitten out of a bloody hole by a mutant rat that pounced into the defensive line.

He hurriedly drew his military dagger to slash, but the mutant rat reacted extremely quickly, dodged with great dexterity, and then bit at the soldier's other foot.

Although the soldier dodged the mutant rat's bite, in this case, he simply could not continue to shoot.

Seeing that the situation was not good, his companion had already tilted his fire, wanting to help him fend off the mutant rats that followed.

But even so, two more mutant rats broke through the fire blockade and pounced into the defensive line.

Seeing this scene, Feng Jun and Shen Chen's faces changed greatly, if one of them was not handled well, the defense line might be torn open a gap, and then the mutant rats in the rear would be able to drive straight in.

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

Before they could reply, they saw a figure leap out of the country and run at a speed that was completely beyond the limits of human beings.
