The sky was full of silver arrows, whizzing and shooting towards the outside of the city, accurately killing a mutated flying insect the size of a human head.
There are mosquitoes, dragonflies, bees, and even the extremely rare flying ants.
However, even though they kept flying in one after another, none of them could get within a hundred meters of the city wall.
Boom! Boom! Boom!
In the sky, a violent explosion sounded almost at the same time, and in an instant, a vacuum zone nearly a kilometer long was cleared in the sky a hundred meters outside the city.
With the arrows fired from the arrow tower, almost no mutant beast can cross the thunder pool even half a step.
Roar!
Suddenly, a roar came from the distant beast tide.
Immediately afterwards, several large figures suddenly appeared in the sky a thousand meters away.
There are mosquitoes the size of eagles, dragonflies more than two meters long, and beetles with golden lights all over their bodies.
Buzz! Buzz! Buzz!
Waves of buzzing sounds came from over there, causing flying insects all over the sky to stir.
Buzz! Buzz! Buzz!
The sound of extremely fast flapping wings continued to sound, and the flying insects in the sky immediately began to fly high into the sky, and at the same time, the density dropped by more than one level.
Boom! Boom! Boom!
Fireballs the size of fists were still shooting out of the city continuously, and violent explosions were also made.
But at this time, it is no longer possible to kill all flying insects.
After all, the number of magic towers is limited. There are only less than a hundred placed in the west of the city, and there are only less than fifty third-level magic towers currently launching attacks.
Even though their rate of fire is extremely fast, reaching the level of three per second, they are still unable to form a blanket bombardment against the flying insects all over the sky.
Buzz! Buzz! Buzz!
The buzzing sound of vibrating wings was getting closer and closer, but Guo Huai, Jiang Zhe, Fu Chengzhi and others standing on the city wall were not worried at all.
They looked calmly at the flying insects above their heads, with a look of anticipation even showing on their faces.
Whoosh! Whoosh! Whoosh!
At this moment, the sound of several sharp weapons piercing the air came from behind, and Park Guochang, who had extremely strong eyesight, instantly saw several dark red balls the size of fingers.
In just a flash, he was already deep into the beast tide.
Boom! Boom! Boom!
Then, violent explosions also sounded, and in the tide of beasts a hundred meters outside the city, several vacuum zones with a diameter of more than a hundred meters suddenly appeared.
At the same time, the flames shot out were still burning fiercely.
The burnt smell mixed with the smell of meat, along with the shock waves formed by the heat waves, kept rushing towards the city wall.
"Damn it, this is too fierce!"
Seeing such a scene, Wu Yong couldn't help but exclaimed: "I feel like this is more powerful than an incendiary bomb!"
"The flame fell on the mutated beast and couldn't be extinguished."
"Hey." Guo Huai chuckled excitedly and continued: "This is inherently more powerful than incendiary bombs, and the rate of fire is also faster."
"You don't even have to worry about the risk of exploding the barrel. Unfortunately, the quantity is slightly insufficient."
"But speaking of which, I still blame you for being such an idiot. Otherwise, this Demon Cloud City might have a few more fifth-level magic towers."
"Damn it, you've done it again." Wu Yong's face froze, and he opened his mouth to curse: "I made a mistake just once, and you're still clinging to me."
"When the monsters attacked the city, I did not do the right thing. I admit it."
"But before the first wave of monsters siege the city, Lord Jiang has already stopped me!"
"And I later secured all the two hours between each wave of sieges. How can you blame me for this horse-trading?"
"Ah, that's right!" A hint of teasing flashed in Guo Huai's eyes, and he immediately smiled and said: "Slip of the tongue, I'm sorry, I forgot, it was really a slip of the tongue."
"Go away." Wu Yong looked a little unhappy and continued to scold without mercy: "I was beaten by those dozen bosses for more than ten hours, and you can forget about it when you step on the horse."
"I still remember your gloating face."
"Haha." Guo Huai suddenly laughed happily and said with a relaxed face: "You can't blame me, who let you take the lead?"
Whoosh! Whoosh! Whoosh!
The two of them chatted without a word, while on the wall beside them, silver arrows shot out one after another, killing flying insects and large mutant beasts running wildly on the ground.
Roar!
The roar sounded again, and the density of flying insects in the sky became lower, and they also flew to higher places.
Just the flame ball shot by the fifth-level flame tower has a flight distance of one thousand meters.
After the explosion, it can cause effective damage to all targets within a radius of two hundred meters.
If within this range, there are not many obstacles, the flames shot out can fly four to five hundred meters.
At this time, even if the flying insects flew to higher places, they could not enter the city.
When the density is low, there are more than 23,000 arrow towers to greet you.
Once the density of flying insects is too high and the arrows cannot reach them, a flaming ball will immediately fly over, and then there will be a "boom", and everything will be clear.
Roar!
Even though the roars continued to come from the depths of the beast tide, they could not make the flying insects and mutated beasts in the sky cross the thunder pool even half a step.
Such a powerful effect immediately made Guo Huai, Jiang Zhe, Fu Chengzhi and others on the city wall breathe a sigh of relief.
After all, no one had done this before, and they still had no idea.
Boom! Boom! Boom!
Deafening explosions, accompanied by waves of heat, continued to blow toward the city, making their faces increasingly happy.
And this one-sided massacre also caused the corpses outside the city to slowly pile up higher and higher.
Even those mutated beasts that can only run on the ground are no longer able to quickly cross such obstacles and launch an attack on Demon Cloud City.
Roar!
Angry roars resounded in the distance again, followed by several deep roars from deep within the herd.
Ouch!
Ga!
Moo!
Hearing such a voice, Jiang Zhe immediately felt something was wrong and shouted loudly: "Are all the evolvers above level four ready?"
"Ready."
Sky-shaking roars sounded uniformly on the city wall, and the evolvers on both sides who were always ready took a step forward in unison.
Buzz! Buzz! Buzz!
At this time, several buzzing sounds were heard in the sky.
Then the bloody mosquito, slightly larger than an eagle, turned into a streak of bloody lightning and headed straight for the city wall.
boom!
Suddenly, a ball of flames suddenly exploded next to him, and the raging flames instantly spread to a radius of a hundred meters.
But in just the blink of an eye, it flew out of the flames intact.
Behind him, the beetle with golden light reflecting all over its body also vibrated its wings at a high speed and flew towards Demon Cloud City quickly.
At the same time, there were yellow wasps, black flies, and dragonflies that were more than two meters long.
When everyone on the city wall saw this scene, their faces suddenly sank, but there was no fear on their faces, and they even took a step forward again.
At the same time, a deep voice immediately said: "Leave that bloody mosquito to me!"
