The concentrated fire of the heavy crystal nucleus cannon brought a devastating blow to the mutant insect army in the sky, so although the number of flying insects left was still staggering, it was no longer able to withstand the cannon fire above the city wall step by step as at the beginning.

In addition, at this moment, the abilities with long-range attack energy on the city wall also shot in unison, so no matter how crazy the impact of these mutant flying insects was, they could no longer break through the double fire blockade constructed by the ability and the city defense weapon, and they were completely blocked above the high altitude of Chu City.

At the same time, the flames burning on the ground also effectively blocked the progress of those ground insects. Insects are naturally afraid of fire, so as long as the flame is not extinguished, it will be difficult for these ground insects to break through the blockade and threaten the city walls.

Finally, the defense line of Nancheng City was stabilized, and everyone on the city wall breathed a sigh of relief. Now all they have to do is support until the energy magnetic field is turned on, and they can rest for a while.

"Finally withstood the ......" Seeing that the city wall was safe and sound for the time being, the bear child was also greatly relieved. After experiencing the battle of the dead city, he has a psychological shadow on these bugs.

However, despite the shadows, the bear child has obviously grown a lot and helped a lot in the battle just now. After all, he is an alien, although his physical fitness is not as good as a strong system ability like Chu Xun, but it is far superior to ordinary people, so he also killed a lot of insects with an alloy dagger that he didn't know where to go.

"Well done!" Looking at the dagger stained with insect blood in the bear child's hand, Chu Xun smiled slightly, then patted him on the shoulder, looked at the Komodo dragon beside him and said, "This guy is also doing well......

Compared to the bear child, the real horror is his Komodo dragon. This guy is simply the best weapon against bugs, don't look at its huge size and slow movements, but it is better because of its rough skin and thick flesh, and it is difficult for ordinary bugs to hurt it. And this guy's tongue is extremely fast, and whenever a bug rushes in front of it, its long tongue will shoot out and roll it into its mouth.

So far, this big guy has devoured an unknown number of insects like a bottomless pit, and even the insect corpses killed by others have been devoured by it. And I don't know if it's an illusion, Chu Xun always felt that this guy seemed to have gotten a little bigger after devouring a large number of insects......

"Of course, this is my little branch!" Hearing Chu Xun praise the Komodo dragon, the bear child suddenly patted his chest proudly, then looked at the swarm of insects blocked by the sea of fire, and asked, "Brother, we should be able to rest next." ”

"Not necessarily!" However, contrary to the bear child's expectations, at the mention of the war, Chu Xun's face suddenly became solemn: "If this sea of fire alone could stop the insect swarm, Baicheng would not have been wiped out in the insect plague in the first place." I'm sure the Zerg must have the means to deal with this sea of fire! And now all that appears are some cannon fodder legions of the Zerg, and the real main legion has not yet appeared. ”

Speaking of this, Chu Xun sighed slightly and said, "The only hope I have now is that the energy magnetic field can be turned on before the Zerg breaks through the sea of fire, otherwise, we will have a bitter battle!" ”

"Isn't it?" Hearing Chu Xun's words, the bear child suddenly shuddered, and the nerves that were originally a little relaxed tensed again.

"There is a situation!" As if to verify Chu Xun's guess, just as Chu Xun was talking to the bear child, Yang Ling, who was using an automatic machine gun to sweep the insect swarm, suddenly changed his face and exclaimed, "Everyone be careful, a new flying zerg has appeared!" ”

Whoa!

Almost at the moment when Yang Ling's words fell, there was a burst of dense and intense, and the sound of flapping wings suddenly came from a distance. Then, I saw a large group of gray-brown flying insects the size of an eagle, with wings spread even more than one meter, and their bodies covered with tiny scales appeared from the distant sky, and flew towards Chu City at an extremely fast speed.

These new mutant flying insects have all kinds of strange patterns on their bodies, and the tiny scales that seem like metal can still reflect a little brilliant light in the sunlight, which looks like a strange beauty.

"This is ......" Looking at this mutant flying insect that looked like a butterfly, but was much uglier than a butterfly, Chu Xun's face suddenly changed!

Yes, most insects are afraid of fire, but there is one exception. Not only are they not afraid of the flames, but they will take the initiative to pounce forward, preferring to be incinerated to ashes in the flames to feel the light and warmth of that moment.

That's right, it's a moth!

And at this moment, what Chu Xun and the others were looking at was a large group of huge mutant moths!

These mutant moths seemed to have a strong purpose, and when they flew over the sea of fire, they suddenly accelerated, and then fell into the raging sea of fire at a very fast speed like a falling warplane!

Moths to the fire, at the cost of their own lives!

Bang bang!

With a dull crashing sound, the thousands of mutated moths were instantly engulfed in flames, but at the same time, they also used their bodies and lives to extinguish the terrifying sea of fire that was originally raging.

Rustle!

As the sea of fire was extinguished by this group of mutant moths, the swarm of insects that had been blocked by the sea of fire finally broke through the obstacle and crawled quickly again in the dense rustling sound.

The sea of black worms is spreading again!

At the same time, a steady stream of mutant moths also flew in from afar, and then joined the mutant insects in the sky, and took the lead in swooping down the city walls.

Compared with those mutant locusts and mutant cockroaches that were equivalent to cannon fodder before, these mutant moths are obviously the real main aerial army of the Zerg. Not only are they huge, incredibly powerful, and extremely fast in flight, but the fine scales covering their bodies also provide them with unimaginably terrifying defenses.

With the addition of these mutant moths, the Flying Insect Legion, which had been beaten back step by step, unexpectedly turned the situation back again. The fine scales on their bodies are so tough that they are far superior to ordinary alloys, and shells below 60mm caliber can only knock them away, but cannot break them, only those shells of larger caliber can really destroy them!

In this way, under the protection of these mutant moths, the firepower network constructed by those city defense weapons on the city wall was suddenly greatly reduced, if it wasn't for the ability to build a second fire blockade, I am afraid that the defense over the city wall has been broken now.

"Fight back, kill all those mutant moths!" Seeing this scene, Chu Yu, who was in charge of the battle command, was also anxious, and while shouting, he tried his best to display his mechanical ability despite his serious injuries and just recovered. Suddenly, a faint red light also appeared on those city defense weapons, not only the attack speed was significantly improved, but also every bullet fired would explode after hitting the enemy, causing more damage to the enemy.

Hearing Chu Yu's words, the strangers on the city wall also immediately mustered up their strength to attack with all their might. It's just that the fine scales on the bodies of those mutant moths don't know what they are made of, and the defense against not only physical attacks is extremely strong, but the defense against elemental attacks is also incredibly strong.

After a round of attacks, they were surprised to find that the attack that could easily tear apart the body of the insect and even shatter the steel fell on the mutated moths, and they could only injure them, but could not completely kill them.

What's more, they also found that when facing these mutant moths, not only did they have a weakened elemental killing ability, but even the power of the elemental effects that came with their attacks was greatly weakened.

In the past, when dealing with ordinary mutant flying insects, as long as they caused a burst of ice rain or thunderstorm, the flying insects in the area covered would be frozen or paralyzed, and they would fall one after another. But on these mutant moths, the freezing and paralyzing effects caused by ice rain and thunderstorms have been weakened a lot, just making these mutant moths move a little stiffer, and it won't take long for them to return to normal, and they can't let them fall from a high altitude at all.

"Is this the main force of the Zerg Air Legion, it's terrifying!" Looking at the dual attacks of the strong supernatural and the city defense weapon, and the mutant moths that gradually approached the city wall with the follow-up insect swarm, a trace of solemnity suddenly flashed in Chu Xun's eyes.

The owner of these bugs was obviously very smart, so he didn't send the main air army at the first time, but used the cannon fodder army to consume Chu City's ammunition. And now that the crystal nuclear cannon has already fired a salvo, it is difficult to fire another salvo in a short time, so the other side has sent its real main force.

Thinking of this, Chu Xun's heart suddenly tightened, and then he hurriedly looked at the ground in the distance.

The main army in the air has already appeared, will the main army on the ground be far away?

Sure enough, at the moment when Chu Xun looked at it, a group of huge, extremely hideous, and terrifying mutant insects suddenly appeared from a mountain in the distance, and then shot towards Chu City at an extremely fast speed!

Seeing the appearance of those giant insects, Chu Xun's face suddenly changed, and a trace of horror flashed in his eyes.

He never thought that the main army on the ground under the command of the insect demon would be this!
