Chapter 188 Day 1, the attack begins

"There is movement!"

Everyone looked towards the entrance of the valley in the distance, and saw a lot of dust flying on the ground in the valley, which soon formed a black cloud, covering half of the sky.

"Looking at this movement, the army of alien creatures should have started to move, and it is estimated that they will reach the waterfall cliffs soon."

Augustine said embarrassedly.

"Everyone, prepare to meet the enemy!"

Zijian and the regiment commander and others gave loud orders. The soldiers on the Marine Corps were divided into two teams, mainly commanded by the soldier leader Zijian and the regiment commander of the Marine Corps.

Liu Cheng had already led the ten members of the Wolf Squad to stand in the back and wait, guarding against the corrupted pterosaurs that might appear at any time.

The twenty garbage man employees had not received formal tactical training and had poor military literacy.

Augustine was even more unwilling to command, and directly told them to go to whichever side the soldiers needed help.

"Boom boom boom boom!"

There were continuous explosions not far away, indicating that the army of alien creatures had rushed to the minefield.

The fingers of the Marines holding the triggers were sweating, and it was hard for everyone not to feel nervous.

Soon, the explosion of the mines stopped completely.

This means that the front troops of the alien army have rushed out of the minefield and triggered all the mines in the minefield.

"It seems that there are tens of thousands of alien creatures."

Everyone inferred based on the speed of the alien creatures stepping on the mines, but they didn't need to make a special inference.

Because the next second, the vanguard of the alien army has appeared in their field of vision.

"Hold steady! Wait until the alien creatures enter the range of the electromagnetic gun, then pull the trigger!"

Although the entire base is a giant hydroelectric power station with too much electricity to use, it takes time for the electromagnetic gun to charge each shot.

If you fire randomly in the air, it will reduce the efficiency of concentrated fire to eliminate alien creatures.

Two thousand meters, one thousand five hundred meters, one thousand meters...

When the alien creatures were about eight hundred meters below the waterfall, the soldier Zhang Zijian shouted:

"Fire!"

"Buzz buzz buzz buzz!"

Dozens of electromagnetic cannons fired, and small ball lightnings with huge power instantly smashed towards the army of alien creatures rushing from the bottom of the cliff.

"Sizzle sizzle!"

Every time the small ball lightning hit an enemy, the bursting plasma could burn these low-level alien creatures into charcoal, leaving a circular charred black area with a radius of seven or eight meters on the ground.

After the electromagnetic cannon fired, a large amount of electrical energy continued to flow into the interior of the electromagnetic cannon along the thick cable connected at the rear, charging for the next shot in ten seconds.

Dozens of electromagnetic cannons fired back and forth alternately, which could avoid energy waste caused by too concentrated firepower, and also avoid too many alien creatures being released during the charging gap.

"People holding kinetic rifles, mainly aim at the alien creatures that pass through the electromagnetic gun firepower and shoot, don't let the fish that slip through the waterfall!"

The commander of the Marine Corps shouted loudly to the other soldiers who did not operate the electromagnetic gun.

"Da Da Da, Da Da Da."

Although the kinetic rifle is not as powerful as the electromagnetic gun, its accuracy is still good.

Seven or eight Marines use kinetic weapons to aim at the same alien creature and fire at the same time. Each person can knock down a first-level alien creature with half a magazine of bullets.

"Woo woo woo woo woo!"

Just as the soldiers fired at full force and suppressed the charge line of the alien creatures, a long humming sound suddenly came from the distance near the valley.

Liu Cheng and his men had heard this sound and were very familiar with it. They immediately recognized it as the sound of the fifth-level alien creature, the Protospermian Snake Bird.

Liu Cheng said:

"He is commanding the alien creatures to fight, and the Wolf Squad is ready to attack!"

"Yes!"

Hearing this, everyone in the Wolf Squad was ready to face emergencies.

On the other hand, the three soldiers, Zhang Zijian, were a little confused, not understanding what Liu Cheng was referring to.

"Can you confirm the direction?"

Augustine asked.

It was not visible in the visual range, which was obviously beyond the perception range of the detective's ability.

Ghost picked up the multi-function scope, and through the long-range detection function, he could barely see a huge snake-like figure, pointing to the valley and replied to Augustine:

"It's in the valley and over there, about a few thousand meters away."

Augustine nodded and said:

"It seems that it is not as stupid as the previous one, and it can hide far away. I'll be back soon."

After that, Augustine jumped directly from the city wall, stepped on the air, and flew towards the valley.

The humming sound of the ancestral snake bird continued for a few more times, and soon a large number of corrupted pterosaurs flew down from the valley towards the city wall.

It was obvious that they came to target the marines on the city wall after hearing the command of the ancestral snake bird.

"Bang! Bang! Bang!"

After the corrupted pterosaurs entered the firing range of the pulse weapons, Liu Cheng led the Wolf Squad to open fire before they could spray acid at the defenders on the city wall.

Although most of them used fewer firearms and their accuracy was somewhat inferior to that of the Marines, and their efficiency in killing the enemy was somewhat lower than that of fighting with their supernatural powers.

But being able to kill the corrupted pterosaurs at such a medium and long distance was already very effective for their current defense.

Of course, not everyone’s shooting skills are bad, such as Liu Cheng and Ghost.

The two of them almost hit the target with every shot, and every shot could hit the weak points of the corrupted pterosaurs, breaking the acid sacs in their necks and killing them with one shot.

Even if the timing and angle are good, one shot can penetrate two corrupted pterosaurs, killing two birds with one stone.

Zijian, who was using a water dragon to attack the alien creatures on the ground, saw this and exclaimed:

“Good shooting skills!”

He was really amazed by Liu Cheng and Ghost. He didn’t expect that the butcher sergeant not only had excellent supernatural combat power, but also had shooting skills comparable to the top sharpshooters in the land forces.

“Sizzle, sizzle…”

The corrupted pterosaurs were attacked and also sprayed a large amount of acid at the wall defenders on the cliff.

The places where the acid splashed and stuck began to smoke and corrode as if a large amount of aqua regia had dripped on them.

At one time, several electromagnetic cannons and more than a dozen marines were injured by the acid sprayed by the Corrupted Pterosaur.

Seeing this, Liu Cheng called out to the Wolf Squad:

"Everyone, use your jetpack to fly into the sky to fight the Corrupted Pterosaur, try to attract their attention, and avoid the marines defending the ground from being affected by the attack!

As for Fu Yan, if you don't have a flying backpack, join the Garbage Man and command them to assist the marines in defense!"

"Yes!"

"No problem, leave it to me!"
