"Boom~"

The large-caliber heavy artillery let out a deafening roar, and the discharged shells continued to whizz in the air, and then burst out in the black wave.

In an instant, the terrifying wave of air accompanied by countless pieces of iron shot in all directions, and the black wave suddenly opened a large area, and a rock-eating rat was blown up all over the sky, and in the center of the explosion, there were a large number of rock-eating rats directly blown apart.

In the whole wilderness, with the roar of artillery, terrifying waves raged in the wilderness, and the dense forest was destroyed in a blink of an eye, and the towering trees fell down one after another.

However, the black wave has not changed in the slightest, and the blank space is covered by black in the blink of an eye, only the raging air wave is constantly impacting.

"Woo~Boom~"

On the city wall, one rocket cannon after another activated, and with a whistling sound, one after another fire dragons shot towards the black waves in the depths of the wilderness.

Soon, in the distance of the wilderness, there were terrifying explosions and clouds of fiery mushrooms rising into the sky, accompanied by the smell of scorched fur and flesh.

"Da~Da~"

Vulcan cannon machine guns burst out of the red torrent, where the torrent passed, everything in the wilderness was swept away like a decay, even the hugging wood could not stop the torrent of strafing, and fell down with a bang.

The red torrent and the black wave collided together, and in an instant, countless blood flowers were set off in the wilderness, and the surging black wave seemed to hit the hard reef at once, and it was instantly torn apart.

The earth was trembling, and terrible waves of qi were coming in waves, billowing smoke filled the city, and blood flowed in the wilderness.

Xie Tian listened to the deafening roar coming from the city wall, and felt the terrifying waves of qi coming over, this qi wave was extremely powerful, and when standing on the city wall, it was very likely that anyone who was not careful would be swept away by the qi wave.

Looking up, the boundless black wave was shattered at once, countless cannonballs were ringing in unison, blooming in the black wave, and the terrible red torrent was constantly sweeping, beating the black wave to pieces, bursting into blood-colored waves.

"This is the war between humans and monsters!"

Xie Tian clenched the spear in his hand and looked into the wilderness.

The black wave seemed to never stop, and endless rock-eating rats were constantly surging from the depths of the wilderness, torn apart one moment, and soon the wilderness was once again covered by the black wave.

There are just too many rock-eating rats!

Although it is only a low-level demon beast, its reproductive ability is too strong, and no one knows how many rock-eating rats there are, all over the mountains, and there is a black sea everywhere.

In this huge group of rock-eating rats, there are also rock-eating rats with intermediate and high-level demon beasts.

These rock-eating rats, except for their larger size, are not much different from ordinary rock-eating rats, but the survivability of these rock-eating rats is very strong.

Even if it was a heavy artillery, as long as it didn't fall on him unluckily, if it was just fragments and qi waves, there would be no damage at all to these intermediate and high-level demon beasts.

With a black wave, these mid-to-high-level rock-eating rats quickly rushed towards the base city, and they wanted to bite down the incomparably tall city wall in front of them with their terrifying sharp teeth.

"Knock~Knock~"

Soon there was another dull sound from the walls.

This is the sound of heavy sniper rifle fire.

Snipers lying on the city wall one by one, or in the dark castle, their target is these intermediate and high-level demon beasts, and the heavy sniper rifle can effectively kill and injure the intermediate demon beasts, and can also cause a little damage to the high-level demon beasts.

There is a special sniper unit in the military of the base city, which is full of sharpshooters, which is specially used to deal with the mid-level demon beasts in the demon beast army.

With the heavy sniper rifle firing, one after another blazing bullets shot towards the intermediate demon beasts and high-level demon beasts in the wilderness, and the intermediate demon beasts and high-level demon beasts were swept away by the terrifying bullets.

However, this hit rate is definitely not too high, and the mid-level demon beasts and high-level demon beasts that are running rapidly in the wilderness are still mixed in the huge army of demon beasts.

Even if you are a sniper who has been trained for many years, the hit rate will be very low.

At the foot of the tall city wall, a large number of rock-eating rats dodged all kinds of attacks, and finally rushed to the foot of the city wall, and one after another rock-eating rats began to frantically gnaw at the hard city wall, they wanted to use their sharp teeth to build this tall city wall to bite down.

As soon as the walls fall, they can rush in and slaughter at will.

"Poof~"

However, soon, from one of the battlements of the city wall, the muzzles of the guns stretched out, and began to shoot wildly downward, the earth was flying, the flesh and blood of the rock-eating rats were blurred, and in the blink of an eye, countless corpses were piled up under the city wall.

"Huh~"

A high-level demon beast arrived at the foot of the city wall, these rock-eating rats are very fast, and very flexible, all kinds of technological weapons almost have no way to deal with it.

Ordinary bullets can't even hurt their fur, and even heavy sniper rifles can only hurt them a little, and it's hard to kill them.

I saw these high-level demon beasts and rock-eating rats walking on the ground in the city wall, and quickly rushed up towards the city wall.

"Kill!"

At this time, the warriors on the city wall finally had a place to use, and with a roar, the warriors began to act one after another, and for a while, swords and swords, one after another fierce attacks beckoned towards these high-level demon beasts.

Xie Tian held a spear in his hand and looked down vigilantly, a black shadow jumped up at a rapid speed, and the hundred-meter-high wall seemed to be flat.

"Drink~"

Xie Tian's eyes opened slightly, and with a loud shout, the spear in his hand stabbed fiercely at the right time.

"Poof~"

The spear was like a dragon, as fast as lightning, and with a flash of cold light, a blood hole appeared in the head of the high-level demon beast rock eating rat that had just emerged, and then it fell straight under the city wall.

"Good~"

When the surrounding soldiers and ordinary people saw it, they couldn't help cheering one by one.

A high-level demon beast was killed by Xie Tian with a shot like this, and with such a powerful warrior in charge, this section of the city wall can be safer.

"Ah~"

However, before everyone could be happy, there were screams from the city wall not far away.

"I'll go~"

Wei Yan's figure flashed, and he rushed over with a long stick in his hand.

Xie Tian glanced at it lightly, and suddenly couldn't help but widen his eyes slightly.

I saw that on the city wall, a high-level demon beast rock eating rat successfully gathered up, and the warrior guarding this section did not succeed in stopping it and let it rush up.

I saw that it was extremely fast, constantly flashing, and everywhere it passed, the terrible claws kept waving, like a fierce tiger descending from a mountain, and there was chaos on the city wall, and the figures kept falling.

The strength of the high-level demon beast is too strong.

Not to mention ordinary soldiers and ordinary people, even low-level martial artists and middle-level martial artists are very dangerous to the top, and it is difficult to resist its sharp claws that contain terrifying power.

"Bang~"

With a dull sound, Wei Yan, who had come to support the past in time, sank the rock-eating rat to the city wall with a stick.

"Here we go again~"

Xie Tian breathed a sigh of relief, but someone around him shouted anxiously.

Xie Tian saw that there was another high-level demon beast rock eating rat that was rapidly climbing up, his blood-red eyes revealing a terrifying fierce light, and the speed was extremely fast, and the hundred-meter city wall was saved up in just a few clicks.

"Drink~"

Xie Tian snorted softly, the figure flickered, and the spear in his hand stabbed, killing the rock-eating rat again.

However, before I could take a breath, under the city wall, black shadows began to rush upwards.

The number of rock-eating rats is just too large!

Although all kinds of technological weapons are powerful, under the continuous attack, the barrels of the guns begin to turn red, and the ammunition also needs time to fill.

So there will be an interval, although the base city will try to arrange as much vitality as possible, alternating with each other, and reducing the intermission time as much as possible.

But even after a short interval, the number of rock-eating rats flocking under the walls is still terrifying.

A large number of rock-eating rats, all of them are low-level, intermediate, and high-level, some are gnawing at the city wall, and some are constantly rushing upward, and the smooth, hard city wall has no obstacle for them at all.

With a slight jump, he could pick up dozens of meters high, and his hard and sharp claws slashed on the city wall, just like cutting tofu on the city wall, and quickly rushed towards the city.

"Kill~"

With a roar of rage, the guns in the guards' hands began to erupt flames, knocking down the rock-eating rats.

The weapons in the hands of the warriors began to wave continuously, the sword light and sword shadows continued to light up, and the rock-eating rats continued to fall towards the city wall.

However, there are too many rock-eating rats rushing up, and from time to time, there are rock-eating rats rushing to the city wall, and suddenly there will be a panic on the city wall, even if it is a low-level demon beast rock-eating rat, it can also cause a slaughter, but it will soon be cleaned up by the warriors on the city wall.

"Da~Da~"

"Boom~Boom~"

"Woo~Boom~"

Soon, heavy artillery, rocket artillery, and all kinds of machine guns roared again, and the black wave in the wilderness was torn to pieces again, and the surging black wave seemed to have lost its follow-up power all of a sudden, and the black rock-eating rats under the city walls were quickly cleaned up again, and everyone could breathe a sigh of relief.
