The feminine sound is harsh and sharp, as if it is not like the sound made by humans.

"What an ugly sound!"

Zhen Jian's face darkened, and he looked up at the place where the sound came.

Fifty meters away in front, there is a row of neat barracks dormitory buildings. One of the dormitory buildings is obviously much taller than the dormitory building next to it.

Inside the tall building, it was pitch black.

The dark windows are like big black mouths, and they have to choose people to eat at any time.

The unpleasant sound just now came from the roof of this tall building.

Zhen Jian secretly picked up the sniper rifle and aimed at the direction of the roof. As long as the target appeared, he would pull the trigger without hesitation.

A feminine voice came from the roof again. "Since you are here, stay!"

Huh! Huh! Huh! Huh!

Suddenly, a sound of wings vibrating at the top of the dark building came. Immediately afterwards, an alien woman with an attractive figure slowly walked out of the roof, then slowly walked into the air and floated in the air.

Zhen Jian looked carefully and found that the alien woman had strange patterns on her face, and her two pointed ears were raised high, looking extremely ugly.

She was wearing black tight armor, holding a weird trumpet in her left hand, and a pair of bat-like blue wings growing on her back. The wings kept vibrating, making a "whip" sound of airflow. Her narrow eyes flashed with strange dark yellow light at night.

Zhen Jian frowned and said to himself: "Made, has the salt mouse become a sperm?"

In an instant, after hearing his words, the alien woman's face turned cold and said calmly, "Show up!"

Whoosh! Whoosh! Whoosh!...

At the top of the building in front, a large group of black alien figures suddenly emerged, with a minimum of hundreds. Like the ugly woman in the lead, they all had a pair of huge bat wings on their backs.

The alien woman led hundreds of bat warriors, holding sharp weapons in the shape of a Grim Reaper's sickle, staying in the air, constantly vibrating her wings, and looking ready to go.

Seeing this, the black dragon hurriedly shouted: "Everyone, protect the chief!"

In an instant, twenty-one senior soldiers, holding sniper rifles and AK47s, came to Zhen Jian, and guarded him firmly in the middle of the team.

"Shoot and kill them!"

Zhen Jian didn't say anything nonsense and ordered an attack directly.

Take a break...

Everyone pulled the trigger at the same time. As the muzzle flames ejected, more than twenty lines of fire shot out and headed straight for the group of bat warriors in the air ahead.

"snort!"

Just as they fired, the alien women seemed to have expected it, and their wings suddenly shook. In an instant, the group of bats floating in the air disappeared.

Zhen Jian and their bullets were all empty.

Looking at the empty night sky, Zhen Jian was secretly surprised and said, "What a fast speed!"

"Sir, they're on top of your head!"

"They flew behind, Mad beat you to death..."

The gunshots rang out again, this time, the gunshots were very chaotic.

In the dark night sky, the group of bats seemed to be like a group of flexible and agile bats, flying all over the sky. Black Tigers and others had no time to aim, and shot them directly, but they all shot in vain.

Seeing that their formation was in chaos, the bats in the air immediately seized the opportunity to counterattack and attack.

In the dark night, a dark blue cold blade suddenly poked out from the void and headed straight to the heads of the two recruits.

Seeing that the two new recruits were about to die under the alien god of death scythe, the black dragon suddenly turned over and shot directly on the blue scythe.

I could only hear a crisp sound of "ding Ding Dangdang" and sparks flew everywhere.

After a painful groan, the blue sickle was beaten and rolled everywhere in the night sky.

Seeing that everyone was still shooting, there were more and more sharp sickles protruding from the night sky.

The black dragon roared filial piety loudly: "Everyone quickly use the Baikru tactics, shoot alternately, and form fire cover!"

After hearing the reminder, everyone calmed down.

Immediately, according to the command of the Black Dragon, a strange tactical shooting began.

Take a break!!!

After a seemingly chaotic strafing, painful groans came from the night sky continuously.

There were several unlucky bat aliens who were shot by AK47, but looking at the defensive shields that exploded on them, it was obvious that they did not suffer fatal damage, but they were not so flexible in their flight.

Seeing this scene, Zhen Jian reminded: "Switch all AK47!"

After hearing the order, several soldiers holding sniper rifles all replaced them with AK47. The automatic shooting speed of AK47 is many times faster than that of sniper rifles.

Anyway, they are too lazy to aim.

As long as you find a black shadow flashing, you can directly follow the Baikru shooting method and interlaced and straggled at a fixed point.

This tactical effect is very obvious, especially in the hands of a group of well-trained and well-equipped senior soldiers, which can exert its maximum power.

Facing the twenty-two AK47 shots all over the sky, more than a dozen bat aliens were instantly shot by stray bullets.

Those bat aliens will have a brief state of falling into the air after being shot, and the dazzling defensive shields on their bodies will not disappear so quickly.

Taking advantage of this opportunity, Zhen Jian and Heilong raised their guns and quickly pulled the trigger and shot them. Only a few consecutive screams were heard.

Several unlucky bat aliens were defeated by defense, and then they fell heavily to the ground and died on the spot.

Soon, the prompt sound of the Wanjie System sounded in my mind:

"Congratulations on successfully killing three captains of the Jiuyou Demon Clan, achievement point +15000, merit point +1500"

"Congratulations on successfully killing two majors of the Jiuyou Demon Clan, achievement points +20,000, merit points +2000"

"Congratulations on successfully killing the Jiuyou Demon Clan..."

The alien woman hiding in the night sky looked extremely shocked, "What gun do they use? Why are the fire speed so fast?"

"I don't know, I've never seen a gun so fast, and the damage is particularly high, so our defense can only resist two guns."

"General Blue Wing, their firing speed is too fast and their cooperation is very tacit. Every time they shoot, they alternately form a firepower net, and we can't get close to it!"

"Send the order to stop the attack, and hide all!"

A strange cold light flashed in the dark yellow child hole of the alien woman, "I underestimated this human major. Their guns are good and they can be brought back to the Demon City for research!"

Speaking of this, she suddenly spread her wings and a pink defensive shield popped up from her enchanting body. In this dark night sky, it looked like a dazzling pink human-shaped light ball, which looked particularly eye-catching.

"Sir, look above our heads..."

"What?"

After hearing the soldiers' reminder, Zhen Jian and others immediately looked up and found that the alien woman suddenly appeared in the night sky dozens of meters above her head, and a defensive shield exploded all over her body.

Looking closely at her chest, she actually wore a pink Shangjiang badge.

I really didn't realize that she was a foreign general. In addition to being able to fly, she would also hide in the air. She didn't feel very powerful?

Looking at her floating in the air, a strange smile appeared in her dark yellow eyes.

Zhen Jian felt something was wrong in his heart and hurriedly ordered: "Kill her!"

Bang bang bang bang...

Twenty-one AK47 fired at the same time, shooting towards the night sky dozens of meters high. There was only a muffled sound of "Peng Peng". The bullets hit the pink shield and all fell to the ground in distortion.

At the same time, the pink shield of the alien woman instantly became darker, and her face turned a little pale.

However, at this moment.

The ugly face of the alien woman and the strange patterns on it suddenly looked like resurrected earthworms, flashing with a faint blue light, slowly creeping and changing.

Immediately afterwards, she picked up the strange-shaped trumpet in her hand and blew it suddenly...

As the trumpet was blown, invisible sound waves poured into the ears of Zhen Jian and others like a tide.

Zhen Jian felt like his brain was shocked by electric shock, his head was dizzy, his eyes were filled with stars, his body was sore and weak, and the guns in his hand fell to the ground without being controlled.

"Not good, it's bad!"

He has felt the threat of death.

In the night sky, the hidden bat aliens held up the Grim Reaper's sickle again, like black lightning bolts, flew down and headed straight for Zhen Jian and the others.

It's almost time for the head to land.

At this critical moment, Zhen Jian suddenly bit his tongue, regaining his brain a very short time to wake up.

Seizing this opportunity, he summoned a god-level defense shield from the storage bracelet.

The god-level defense shield can even resist a nuclear explosion. A mere strange sound wave attack is nothing.

"Boom".

A dazzling golden light ball suddenly appeared out of thin air, and then turned into a huge transparent shield, like a large upside down bowl, firmly covering Zhen Jian and others.

After a series of collisions of "Peng Peng Peng Peng", the bat aliens who almost killed Zhen Jian would never have thought that such a huge protective cover would pop up suddenly, blocking them outside.
To be continued...
