Although the Dragon Empire often manipulates some subspecies of drakes and lower dragons to consume other kingdoms through behind-the-scenes influence.

However, looking at every war in which the Dragon Empire was directly involved, there was no doubt that it was a violent offensive that ended the battle quickly.

The Dragon Empire is very powerful, but the growth rate of dragons is the biggest shortcoming of the Dragon Empire.

Even if it's just a half-blood dragon, it's just an "inferior dragon beast", even if the growth rate of these dragon races exceeds that of a true dragon, it is obviously not something that can be cultivated in a short time.

Can they withstand such attrition?

From the previous report, the number of powerful dragons exceeded two thousand, and there was no doubt that the size of the tyrant's subordinate dragons was no less than the size of the troops that only a dragon duke in the Dragon Empire could have.

This is also the puzzle of all dwarven commanders.

Although they didn't know how the tyrant's dragon group appeared in the sea of trees secretly, it must represent that the dragon empire had evacuated the troops of a certain area.

In this case, shouldn't the Dragon Empire choose the tactics of quick victory?

The pressure from the two empires of the Beast Empire and the Deep Sea Empire can't threaten the Dragon Empire?

Before the arrival of this offensive, there were even dragons who thought that the "tyrant" had withdrawn.

However, who knows, the actions of the "tyrant" completely violated common sense.

Why fight a protracted war with the kingdom of the mountains.

What's more.

Even if it is broken and the mountain kingdom is destroyed, what good will it do to the Dragon Empire?

Could it be that the Dragon Empire can still cross the elven kingdom and disperse its troops and occupy the mountains?

For what?

In order to destroy the elven kingdom, plan to besiege the elven kingdom from two directions?

No matter how you think about it, it is not in the interests of the Dragon Empire.

Not to mention that if you wipe out the tyrant's dragon group, even if you only consume half of it, it will be more of a loss than a gain for the Dragon Empire, right?

The metal resources and gem resources of the mountain kingdom have been almost consumed.

Why did the Dragon Empire choose to conquer the mountains?

Could it be that the "tyrant" and the mountains have an extremely deep hatred?

It's impossible, the only dragon that has clashed with the mountains is the leyline dragon.

If it was a ruby dragon, an emerald dragon, or even a sapphire dragon, or a steel dragon, they would be able to understand it somewhat.

However, the Wind Dragon......

Incomprehensible.

Could it be that it is just to attract the attention of other empires? Lure them into attacking?

In essence, the "tyrant" has returned to the Dragon Empire?

But, understandably or not, the tyrant's dragon horde has shown a definite offensive.

The mountains must face a high frequency of harassment from the "Tyrant's Wings".

Moreover...... It's fine if you only have to face enemies in the air.

In the previous war, there seemed to be a leyline dragon in the tyrant's dragon group.

They also need to be on guard against attacks from underground, as well as those of the Blue Dragons, who have the ability to unleash terrifying lightning with the ability to resemble giants.

Green Dragon, Blue Dragon, Wind Dragon, Earth Leyline Dragon, White Dragon.

In addition to the Black Dragon and Red Dragon races, this group of dragons led by the "Tyrant" includes almost the most powerful dragons of the dragons.

These dragons all need to be defended.

It's not just storm dragon pressure.

The dwarven commanders argued.

But.......

At this time, the door of the military chamber was suddenly opened, and when the commanders looked at the opened door with different expressions, they only saw the figure of a goblin.

Unlike the dwarves, this goblin appeared rather emaciated, with somewhat distracted eyes:

"The imitation of the ancient machinery is ready, which of you has time to test it?"

At this moment, the dwarven commanders fell into an indescribable silence.

Imitation, ancient machinery?

......

Four days later.

Night fell again.

The figure of the flying dragon of the bird is revealed above the high sky of the mountains.

Although the total number of beak-feathered wyverns has reached five hundred, there are many recruits among them, but there are no of them among these beak-feathered wyverns led by the United Bird Wyvern himself.

This Wyvern army, consisting of forty-five Beak-Feathered Wyverns and five Poison Feather Wyverns, has all been gifted dozens of times.

It can be said that each of them can lead a team of fifty wyverns on their own.

This is the elite team of the Beaked Feather Wyvern.

And this time, the goal was to attack a fortress that had been guarded by a large number of dwarven troops.

Previously, the frequent harassment of other wyverns in other positions finally made these dwarves choose to support under pressure.

And this time, the Bird Wyvern is going to bring its troops and launch an offensive against the fortress.

The process is still in accordance with the previous offensive process.

Relying on the cover of the night to approach and descend from a high altitude, he suddenly spewed high-pressure wind bombs en masse, and then immediately retreated, allowing the poisonous feather wyvern to set off the poisonous wind and poisonous fog to cover, withdraw and rest, and prepare for the next attack.

The line of sight swept over the fortresses scattered throughout the mountains, and the command of the Flying Dragon, along with the sweep of the wind elemental, spread throughout the entire wing group.

One after another, with an average body length of more than thirteen meters and a wingspan of thirty meters, the behemoths relied on the night, their hard and thick beaks and mouths were closed, and they inhaled air sacs from the air as they flew all the way, and the wind elements that were embedded with life force poured out of their bodies, gathered and compressed in the cavities of their beaks and mouths.

The force of the high-pressure wind bombs, which are almost spherical, almost stretches open their beaks.

"Attack—"

It wasn't the sound of the pipe, but the sound of the long winged tail paws flapping.

In the next moment, the three teams that were staggered and divided into three teams, their wings spread out like dark clouds, and the air sacs once again spewed out the wind element embedded with life force.

It was also at this moment that the beaked feather wyvern opened its beak mouth slightly-

The nearly invisible sphere, with a pop that broke away from its beak, flew out and bombarded towards the ground fortress.

Boom Boom!

！

Not concentrated on one point, but on the side of the fortress.

Fifteen high-pressure wind bombs swirled at high speed, and the tough shells connected by life force around them burst apart, and a violent storm exploded.

In an instant, countless earth, rocks, and flying sand were rolled up, and a funnel-shaped storm vortex swirling at high speed was violently formed.

Between the claw-like blades of the wind, there were pieces of metal shards, shadows of earth, rocks and flying sand.

The solid, heavily cast shell of the fortress had been torn off in the midst of the storm.

The heavy fortress shell was swept into the wind vortex.

Although, through the storm, soon the light of the runes lit up, the rune weapon specially designed to fight the wind elemental was working.

The continuous destructive power of the wind vortex is decreasing at a rate visible to the naked eye.

However, at this time, as the lowest beak-feathered wyvern flapped its wings and flew into deep space, another team of fifteen beak-feathered wyverns rotated below, and they opened their beaks and mouths as the wind elemental in the airbag propelled them.

The invisible high-pressure wind bomb shot to the ground in a high-speed whirling attitude.

However......

At this moment, in the distance, a dazzling light bloomed.

In the midst of a humming sound, a glimpse of an explosive arc of electricity pierced through the air.

In the purple trail, metal projectiles with strange runes flew out.

Although the moment it caught the dazzling light, the beaked feather wyvern that was targeted opened its storm shield, it .....

Rumble!

！

There was no explosion, only an electric arc.

A metal orb engraved with runes directly shattered the high-speed circulation life force shield, tore through the storm, and slammed into the beaked feather wyvern's body.

In the midst of a heavy sound, the Beak Feather Wyvern let out a terrible scream, and the blood rained down in the torn storm, thousands of meters in the air.

However, there is more than one dazzling brilliance.

Visible to the naked eye, in the dazzling firelight, cannonballs were fired one after another.

The Beakfeather Wyverns also unfurled their storm shields almost entirely.

However, these cannonballs were not the previous metal projectiles with a faint purple arc of power that pierced through the storm shield.

It's the elemental bombs they've encountered again and again these days.

These elemental bombs, which had a range of enough to cover a distance of ten kilometers, burst into flames filled with violent fire elemental power, and were easily blocked by the storm shield that the Beakfeather Wyverns opened with all their might.

However, in the impact of these elemental bombs, a faint purple glimpse suddenly appeared.

The shield shattered, the storm cracked, and the purple arc metal projectile pierced the sky.

The rain of blood once again bloomed from the sky.

One after another, beak-feathered wyverns fell from the sky with a mournful roar as their companions quickly lifted and flew up.

Amidst the roar and roar, the beaked feather wyvern, which had been hit hard, launched a final attack on the dwarf on the ground.

Look at the Dragon's Lair Tyrant.
