If spiders are assassins of the insect kingdom, accustomed to ambushing and killing enemies with poison and cobweb traps, then there is another creature that is the assassin of the insect kingdom.

This creature is not highly venomous, it has no cobwebs, they never set traps, they just quietly lock onto their prey, then get close to their prey, and finally launch a swift attack in less than 0.01 seconds, killing in one hit!

They are the most belligerent and fierce killers in the insect world, they dare to challenge all enemies, even if they are a hundred times stronger than themselves, they dare to attack wildly until they are torn apart or torn apart by them!

They are also the most cruel and cold-blooded executioners in the insect world, for them, anyone can be their own food, even if it is a mate who has just mated, they will mercilessly tear it to pieces and swallow it in their stomachs!

That's right, what appeared in front of Chu Xun at this moment was this kind of terrible killer that he was most afraid of and didn't want to face in his heart-the Mutant Mantis Army!

These mutant mantis are extremely large, each measuring about 2 meters in length, and from a distance they look like green motorcycles.

The appearance of these mantis was not much different from before the mutation, except that the sickle-like forelimbs seemed to become stiffer and sharper. The sharp "scythe" has a row of slightly curved serrations on it, and a sharp hook at the end, and it is clear that once caught by these terrible creatures, it is a fool's dream to break free.

In addition to the most iconic "broadsword", the mantis's sharp chewing mouthparts are also terrifyingly destructive. After grabbing an enemy, the praying mantis will quickly tear the enemy's head with its sharp mouthparts, completely destroying the enemy, and then slowly savor the enemy.

At this moment, these green killers were rushing towards Chu City at an extremely fast speed from the distant mountain. They are so cruel and cold-blooded that even other insects that are also part of the Insect Legion will not hesitate to tear them apart with their claws if they stand in their way, and then chew them up and swallow them as they run.

In the face of these green killers, the originally menacing black worm sea suddenly retreated to both sides like a frightened rabbit, taking the initiative to open up a way forward for the mantis army.

"Damn, this!" Just when Chu Xun was in a solemn mood because of the appearance of the praying mantis legion, Yang Ling on the side seemed to have found the information, his face changed, and he said in a deep voice: "These mutant mantis are all real second-order creatures, they are shaped like lightning and attack like thunder, although the body's defense is not too strong, but the vitality is extremely tenacious, unless their bodies are completely destroyed, even if their heads are destroyed, they can still survive for more than a week!" ”

Speaking of this, Yang Ling couldn't help but clench his fists, gritted his teeth and said, "Although this thing is difficult, it has been extremely rare in the past, and it is all acting alone. I didn't expect that so many would suddenly appear now, Chu Xun, we are in big trouble! ”

"Of course I do!" Hearing Yang Ling's words, Chu Xun's mood became even more solemn.

The Flying Insect Legion has greatly increased in strength after the addition of mutant moths, and in order to block them, the abilities with long-range attack capabilities on the city wall have almost exhausted their strength, and even Chu Yu, who has just recovered from serious injuries, can't take a break, and fully control the city defense weapons to fight.

In other words, at this moment, neither Chu Yu nor other abilities with long-range attack capabilities were able to provide them with firepower assistance, and if they wanted to block the invasion of this green army, they could only rely on themselves!

"City defense soldiers, prepare for battle!" At the same time, Chu Yu also realized the seriousness of the matter. In desperation, he could only use a hole card that he didn't want to use!

"Yes!"

After receiving Chu Yu's order, they had been on standby, and the thousands of elite soldiers who were responsible for guarding the city wall finally took action. They clenched the large-caliber automatic rifles in their hands, then sorted out the war equipment such as magazines and grenades, and finally knelt down on one knee, put the muzzle of the gun on the city wall, and aimed at the green army that was shooting from a distance!

Letting the city defense soldiers participate in the battle was Chu Yu's last choice, and it was also the last choice he wanted to make. Because although these city defense soldiers have undergone hard training, their marksmanship is good, and large-caliber rifles with depleted uranium armor-piercing bullets can also cause effective damage to mutant insects, but after all, they are just ordinary people, once those mutant insects climb the city wall, then these soldiers who lack melee ability will definitely suffer a bloody massacre!

But now, if you don't want to use it, you can only use it!

"The first squad is ready, follow the established attack sequence, and fire in 10 seconds!"

"The second squad is ready, follow the established attack sequence, and fire in 10 seconds!"

"The third squad is ready, follow the established attack sequence, and fire in 10 seconds!"

……

After the preparations were completed, there were also bursts of cheers among the city defense soldiers. Then each soldier began to open the safety of his weapon, loaded his bullet and put his finger on the trigger.

"Fire!"

Ten seconds passed in a flash, and in these ten seconds, those mutant mantis also crossed the blackened ruins of the entire sea of insects at an extremely fast speed, and approached within 1,500 meters of the city wall of Chu City!

And almost at the moment when the mutant mantis entered the 1,500-meter range, a loud shout suddenly sounded, and then each city defense soldier aimed at the mutant mantis in his area of responsibility in accordance with the attack sequence specified in the previous training, and pulled the trigger.

Bang bang!

In an instant, the fierce and dense gunfire also resounded in the sky. The salvo of thousands of people was so intense that it silenced the hiss of the mutated insects in the sky.

The large-caliber rifles used by these city defense soldiers have been specially modified to be extremely powerful, and together with the 7.62mm caliber depleted uranium armor-piercing bullets used, they can shatter the second-order alloy. So almost at the moment when the violent gunfire rang out, the dozens of mutant mantis that rushed to the front shook in unison, and pale green insect blood was also splattered on their bodies. And as the blood of the insects splattered, the bullet holes on their bodies, the size of an adult's fist, also appeared in front of everyone.

"Damn......" However, seeing this scene, Chu Yu, who was in charge of commanding the operation, couldn't help but let out an angry scolding.

The weapons used by these soldiers are all modified from the pre-Cataclysm portable rifle called "DRD Paratus-18", although the caliber is still 7.62x51, but it is far more powerful than the original, and can easily blow up a light armored vehicle. However, this weapon that is enough to explode a light armored vehicle can only hit these mutant mantis with a penetrating wound the size of a fist, so you can imagine how strong the defense of these mantis is!

Second-order creatures are second-order creatures after all, even if they are not known for their defense, mutant mantis can't be killed so easily!

"Squad Single, change magazines and use concussive blast bombs to slow down the enemy's impact!" Finding that the salvo of the city defense soldiers could not effectively kill this terrifying creature that was extremely fast and powerful, Chu Yu immediately issued a new order!

"Yes!"

Hearing Chu Yu's words, the teams that were sorted as single numbers immediately stopped designing, then took the blue drum handed by the ammunition supplier next to him, inserted it under the rifle, and then aimed again and pulled the trigger.

Boom Boom Boom!

In an instant, thousands of large-caliber concussive impact projectiles fell into the mutant mantis legion, and then exploded with a blinding light and a deafening loud noise.

At the same time, a violent shock wave also swept wildly with the explosion of those concussive impact bombs, and under the sweep of this terrible shock wave, the speed of those mutant mantis legions was also slightly slowed down, and their eyesight also seemed to be affected, and their actions became a little stumbling, and even a few mutant mantis fell to the ground because they did not stand firmly, and then were torn to pieces by the same kind that surged up later.

"It worked!" Seeing the concussive impact bomb take effect, Chu Yu's eyes suddenly lit up!

Hiss!

But at this moment, a sharp hiss suddenly resounded through the sky. Then, as if they had received some command, those mutant mantis actually found the right direction again, and then accelerated again, just like that, facing the rain of bullets, rushing towards Chu City!

"Damn, everyone converts armor-piercing shells and fires with all their might!"

Seeing that the effect of the concussive impact bomb was gone, Chu Yu's face changed again, and in desperation, he could only order again and fire with all his might, hoping to kill some more mutant mantises.

However, the mutant mantis is worthy of the most terrifying mutant insects, they are not only amazingly fast, but also extremely tenacious, even if their bodies are beaten into a sieve, as long as they are not completely torn apart, they can still continue to charge.

So soon, the battlefield observer who was in charge of observing the distance also let out a terrible cry: "The enemy is 1,000 meters away, and it is expected to break through the fire blockade and make contact in 30 seconds!" ”

In the last 30 seconds, these praying mantis will rush to the wall and start slaughtering!
