Zhang Xiaoyu also saw this legendary beast tide for the first time, and at this moment, he saw the sky black and oppressive, and his eyes lit up.

"Damn, a lot of calories, the system should be able to be upgraded this time. ”

Next to him, the vice president, who originally had a gloomy face, couldn't help but be slightly stunned when he saw Zhang Xiaoyu's expression.

"What are you thinking, why are you so excited. ”

"It's okay, it's okay, it's just that I've never seen such a spectacular situation, and I sighed for a while. ”

Putting away the thoughts in his heart, Zhang Xiaoyu began to think that he needed to find a separate opportunity to hunt demon beasts and get enough calories for a while.

On the one hand, with calories, he has sustained combat effectiveness, and on the other hand, upgrading the system and converting free attribute points are also the top priorities.

His own natal divine weapon had already been successfully refined.

And this Sword of Nothingness requires him to have strong enough spiritual power to be able to drive it.

If it goes well this time, he should be able to raise his spiritual power to a higher level, and when the time comes, with the Sword of Nothingness, it will also be a great boost for him.

A few kilometers further on.

The demon beast that was originally entrenched in the sky also seemed to have sensed it, and instantly became irritable.

Quack.

The demons roared in unison, and in an instant, a noisy cry came into the ears of everyone present, making people's eardrums ache.

Even the students of Wuda University had already gone through a year of killing training, and at this moment, when they saw the demon beasts that covered the sky and the sun attacking, they couldn't help but become a little flustered.

"Steady, the fighter is covered with the Vulcan cannon, and put down the Yuanli cannon first. ”

The dean of the War Academy let out a low shout, and his voice actually overwhelmed the screams of the demon beasts, and clearly reached the ears of every martial artist.

"Vulcan cannon, prepare, kill me. ”

On the fighter plane, all the senior students of Wuhan University were flustered, but they were much calmer than those freshmen.

As soon as the command full of killing intent and anger fell, on the fighter plane, accompanied by the sound of blood emitted by the operation of the machinery, on each fighter, there were ten Vulcan cannons stretched out.

The barrel is two meters long, black throughout, and the barrel is twenty centimeters in diameter, which looks a few points thicker than an adult's arm.

"Fire, fire, fire............"

A neat command sounded almost simultaneously.

Boom, boom, boom.

The explosion resounded through the heavens and the earth in an instant, and the barrel of the Vulcan cannon spat out dozens of miles of flames, and the special bullets rained down on the opposite group of demon beasts.

Boom, boom, boom.

Another popping sound.

This Vulcan cannon is also a special weapon, after the bullet is issued, it can explode instantly, and it has great lethality.

At this moment, the demon beasts flying in the sky are all low-level demon beasts, and the power of the Vulcan cannon can easily kill them, and in an instant, the sky is full of broken meat and the broken corpses of demon beasts falling.

The entire sky, from the previous black, has turned a blood-red, and the pungent smell of blood clearly enters everyone's nostrils, and it seems to turn into hell on earth in an instant.

Bai Yu fighters, each with ten Vulcan cannons on it, fired together, almost forming a dense rain of fire in front of the demon beast, the sound of guns and cannons was deafening, overshadowing the screams of the demon beasts, and also overshadowing the fighting sound of the warriors.

In just ten minutes, the demon beasts that died under the fire tongue of the Vulcan cannon have exceeded hundreds of thousands.

The ground had already been covered with the corpses of demon beasts, and the blood gathered in large patches, and finally formed a long red river like a river, flowing slowly.

Among the martial artists present, the high-level martial artists were still stable, and those new and low-level martial artists were all pale at the moment, and some even began to vomit on the spot.

Although they had been trained for a long time, the horrific sight of the killing still made many people feel uncomfortable.

The fighter attacked with the Vulcan cannon, and at the same time, the Yuanli cannon also landed smoothly.

The birds and monsters in the sky, after the first round of Vulcan cannon attacks, not only did not decrease, but more and more.

High-level demon beasts continued to rise into the air, joined the group of demon beasts, and began to chirp and command.

The previous group of demon beasts was dominated by first- and second-grade demon beasts, and the Vulcan cannon could destroy its defenses and kill it almost instantly, while the third-grade demon beasts needed some time to kill them.

Coupled with some flying birds and demon beasts, the speed is extremely fast, and they can dodge the attack of the Vulcan cannon, and they see that the first line of defense is about to be broken through.

"All fighters shoot freely to dodge, kill low-level demon beasts first, and prepare for the pilots. ”

As the voice of the dean of the war academy fell, the fighter plane, which had already put down the Yuanli cannon, began to move quickly.

On the fighter plane, a group of warriors wearing special armor, holding kryptonite weapons, flew out of it.

These warriors, all of whom are warriors of the War General Realm, carry a winged flying machine behind them, and specialize in picking out the three-grade demon beasts.

Generally speaking, the ordinary demon beasts of the third grade are similar to the warriors of the Terran junior war general realm, of course, this is talking about a beast soldier-level demon beast, if it is a beast general-level demon beast, it can easily compete with a martial artist of the intermediate war general realm.

Three-grade demon beasts, if it weren't for special bloodline demon beasts, it would be almost impossible for a beast emperor-level demon beast to appear, so these flying soldiers were not difficult to deal with, and Wuda's side was temporarily in the upper hand.

"Wuda actually cultivated a group of Iron Heroes. ”

Zhang Xiaoyu muttered.

These should be Wuda's hole cards, and he has never seen this kind of special forces on weekdays, but today is the first time he has seen it.

"All combat personnel withdrew from the combat area, and the Yuanli cannon was ready to be fired. ”

The command sounded again, and those flying soldiers, without any ambiguity, killed a group of demon beasts again before leaving, and sped up to leave the battlefield.

There is the cover of the Vulcan cannon, and there is no damage to people for the time being.

And the battle on the ground has not begun, but everyone is waiting quietly with gloomy faces and weapons in hand.

They knew that as soon as the Yuan Force Cannon passed, it would be their time to play.

Airplanes......

A clear sound suddenly sounded.

The barrel of the huge Yuanli cannon slowly lifted, and the muzzle began to glow with a scorching white light.

Zhang Xiaoyu was also quite curious about this weapon, so he stared at the Yuanli Cannon at the moment and observed quietly.

"This Yuan Force Cannon can only fire two rounds in total, after firing, it will be reloaded, cooled, and re-launched after half an hour, and after two rounds of the Yuan Force Cannon, all the warriors will rush forward and kill the demon beast.

High-level tutors, stop high-grade demon beasts, and definitely not let them rush into the student group. ”

The vice president ordered coldly, and at this moment, the Yuan Force Cannon was also prepared.

Airplanes......

There was another long roar, and at the muzzle of the cannon, the heated white light burst out in an instant, forming a thick white pillar of light, pouring into the sky.

A total of thirty pillars of light rushed into the group of demon beasts in an instant.

At this moment, it was unusually quiet.

There was no scream of the demon beast, no shout of the warrior, only the hum of the muzzle of the cannon that had just disappeared, and all the demon beasts that were hit by the white pillar of light disappeared as if the ice and snow melted, and there was no corpse left.

In one attack, thirty pillars of white light were, and at least a million demon beasts died under the attack of the Yuan Force Cannon.

There was a vacuum in the sky for a while, and the breath of death enveloped the entire wilderness area, which was a feeling of dead silence.
