A rumbling sound sounded in the wilderness, and the earth trembled slightly, as if thousands of troops were surging towards the base city.

In the dense forests of the wilderness in the distance, large flocks of birds rose to the sky, and patches and patches of trees were constantly shaking, and even falling down with a bang.

"Squeak ~ Squeak ~ "

It was as if thousands of birds were chirping incessantly, faintly from far to near, and the sound gradually became louder and louder.

In the distant sky, several huge demon beasts released a terrifying aura, attracting the wind and clouds in the sky.

In the blink of an eye, the sky was covered with dark clouds, lightning and thunder, and at the same time, terrible winds began to wreak havoc, rolling up countless fallen leaves in the sky to form a huge tornado that ran through the heavens and the earth.

These huge demon beasts stepped on the void one by one, as if they were strolling leisurely, gently stepping in the void, seemingly slow, but the speed was very fast.

Before the demon beast arrived, the terrifying aura had already spread in the air, making all kinds of countless demon beasts below run forward desperately and rushed towards Hongdu Base City.

"Run~"

"Run~ The demon beast is attacking the city, the demon beast is attacking the city!"

When Xie Tian, Wei Yan and the others heard the rumbling roar, their faces had already changed greatly.

Before everyone could react, figures flashed out of the wilderness, and the speed of these figures had soared to the extreme, and they roared loudly as they walked.

"Demon beast siege!"

When everyone heard this, their faces suddenly changed dramatically.

"It's only been two years, and the demon beasts are coming to attack the city again?"

Su Yu frowned tightly and muttered to himself.

"Two years~"

Xie Tian's eyes looked into the depths of the wilderness, carefully felt the trembling of the earth, felt the rolling sound coming from the wilderness ahead, and the scene from two years ago came to his mind.

That time was also a monster attack, Xie Tian's parents, as soldiers, left home in a hurry after hearing the air raid siren, and never came back.

"Demon beast!"

Xie Tian clenched the spear in his hand, and his eyes burned with rage.

"Thank God~"

Wei Yan looked at Xie Tian who was in a daze, pulled Xie Tian's clothes and said anxiously: "Hurry up, once you are surrounded by demon beasts, even if you are a strong martial artist, you will be in danger." ”

"Let's go~"

Xie Tian came back to his senses, and as soon as he turned around, the whole person quickly returned towards the base city like a gust of wind.

Wei Yan followed closely, his face was also very ugly.

The same is true for the people of the five-star team and the tiger team, Li Hu carried Song Ke on his back, and the speed was also extremely fast, like a fierce wind, where he passed, flowers and trees were blown by this terrible wind.

"Fast~Fast~"

Li Hu said to his teammates as he walked, he was a high-level martial artist and his speed was very fast, but his teammates were only intermediate-level martial artists, and his speed was much worse.

Looking at Xie Tian and Wei Yan again, the two of them had disappeared from view.

"Squeak ~ Squeak ~ "

The sound was like a tide, getting closer and closer, and at the same time, from time to time there were teams of warriors fleeing from the wilderness, many of whom looked very embarrassed, with colors on their bodies, or their injured teammates on their backs and hands between them.

"Open it for me~"

In the wilderness behind, there was a roar, and faintly a sword that rose into the sky could be seen disappearing.

"Boom~"

With a terrifying loud noise, the earth trembled, and a terrifying wave of qi rushed in all directions, and the dense forest in the wilderness was forced to cut out a path that was thousands of meters long and more than ten meters wide by this knife.

Then an extremely embarrassed figure, holding a large knife, appeared with a yellow light all over his body, and the speed was very fast, almost disappearing in a flash.

As soon as the man walked by, the terrible detonation sound and the fierce air currents began to explode in the wilderness.

"Badao Mountain!"

Li Hu's eyes widened slightly, and he immediately recognized this person.

Tyrant Sword Mountain, Gangjin Warrior, an extremely powerful and terrifying warrior.

However, at this time, the sword Gao Shan was extremely embarrassed, and the combat clothes on his body were bitten to pieces, and at the same time, he could faintly see that there were several places on his body where the white bones of the forest were exposed, and the flesh and blood were gone.

"It's terrible~"

Li Hu's speed couldn't help but speed up a little, but when he looked at his teammates, he couldn't help but say anxiously: "Hurry, hurry~"

Looking at the wilderness again, the rumbling sound is getting louder and louder, the squeaking sound is like a surging wave, it is already within reach, and a black mouse with a head length of more than one meter and a height of dozens of centimeters can be seen running continuously in the wilderness.

"Rock-eating rat swarm!"

When Li Hu saw it, he was immediately frightened, and he couldn't take care of his teammates, carrying Song Ke on his back, and his speed began to soar to the extreme.

Rock-eating rats are just low-level demon beasts, one or two demon beasts, or even dozens or hundreds, but every time a demon beast attacks the city, what the base city is most afraid of is the rat colony.

Because the number of rats is so huge, millions, tens of millions, or even hundreds of millions of rock-eating rats form a terrible rat tide, once they fall into the rat tide, even if they are Gang Jin martial artists, they are extremely dangerous.

This is the case with the sword mountain just now, he is powerful, but he almost died in the group of these rock-eating rats.

Xie Tian's speed is extremely fast, and when he reaches the innate realm, Xie Tian's speed also easily breaks through the speed of sound, and when he goes all out, the speed can break through the speed of sound.

So in less than 3 minutes, Xie Tian returned from the wilderness to the gate of Hongdu Base City.

"Woo~Woo~"

At this time, there were bursts of piercing sirens in the sky above the entire Hongdu base city, and the air defense sirens continued to sound, and at the same time, in the corners of the base city, one by one the radio horns began to sound the news of the monster siege over and over again.

"All citizens of Hongdu Base City should pay attention ~ Demon Beast Siege, Level 2 Alert, Demon Siege, Level 2 Alert!"

"Please all warriors immediately go to the city wall to participate in the battle, please all warriors immediately go to the city wall to participate in the battle!"

"All soldiers will return to their posts immediately ~ All soldiers will return to their posts immediately ~"

"All adults, men and women, immediately go to the armament department to collect guns and ammunition and go to war!"

"All minors immediately enter the bomb shelter, all minors immediately enter the bomb shelter~"

With the continuous sounding of the radio room in every corner of the base city, coupled with the piercing air defense sirens echoing in the air, the originally lively Hongdu base city immediately changed.

The teachers in the school began to organize the students to enter the air-raid shelter, and then one by one the teachers put down the textbooks in their hands, the combat uniforms on the ship, took their weapons, and quickly gathered together, forming a phalanx and running towards the periphery of the base city.

Here and again, the faces of the people who were enjoying life changed greatly, and the shops closed their doors as quickly as possible, put down everything in their hands, and quickly began to move towards the armament everywhere.

On the busy traffic artery, the car that was in a rapid situation suddenly seemed to press the pause button, everyone got out of the car one after another, and the child was quickly sent to the air-raid shelter.

The car turned off, the key was not pulled, the door was closed, and they quickly gathered, not knowing each other, but they suddenly became comrades-in-arms, forming a phalanx, and quickly meeting at the designated place.

The base city is armed here.

The huge warehouse door was opened, revealing countless weapons and ammunition stored inside, and a team of adults, both men and women, lined up, swiped their identity cards, received guns, received low-level combat uniforms, and low-level chopping knives, and then walked towards the periphery of the base city, while quickly putting on combat uniforms and attributes the guns in their hands.

It was as if they had been trained again and again, and everyone was silent to each other, except for the sound of running.

In the face of the attack of demon beasts, in the face of the life and death of human civilization, everyone has been trained in this area again and again from childhood to adulthood, even if it is a primary school student, at this time it is also very orderly under the leadership of the teacher, quickly hid in the underground bomb shelter.

In the central area of Hongdu Base City, in one martial arts community, with the sound of the air defense siren and the sound of the radio, the faces of everyone who heard it changed greatly.

One by one, the warriors quickly returned to their homes, put on combat uniforms, combat boots, brought their own weapons, and finally took a look at their wives and children, young and old, resolutely, quickly gathered in their own community, and then under the leadership of powerful warriors, they quickly supported the city wall on the periphery of the base city.

In the most central and core villa area, figures flashed towards the periphery of the base city, and behind them, the air exploded, and a terrible sonic boom exploded.

"The monster is here again~"

Here in the castle of the Ouyang family, a figure walked towards the periphery of the base city step by step, seemingly a slow pace, but the speed was extremely fast, in the air as if the end of the world was close at hand, just a blink of an eye, Ouyang Zhan's figure had disappeared from everyone's field of vision.

In addition to him, in the sky above the center of the base, four figures swayed up one after another, stepping on the void, looking at the outside of the base city with a stern face.

Li Ben, a military general wearing a military uniform and a serious face; Qin Rong, who is heroic and charming, the town guard of Hongdu Base City of the Dragon and Tiger Martial Arts Pavilion, and a man and a woman, the two are flying side by side in the air, Huo Yun and Huo Ying are brothers and sisters who look very similar.

The five Lingyun Grandmasters of Hongdu Base City all flew across the air towards the periphery of Base City.

"Lingyun Grandmaster~Lingyun Grandmaster~"

When someone saw them flying in the air, they couldn't help but cheer and jump, and their eyes were full of adoration.
