The year of the mountains is 975, and the year of the dragons is June 1452.

With the arrival of summer, the fire element gradually increases, and the sun begins to scorch the creatures on the ground.

Dwarves have long been accustomed to heat and cold.

But..... They are clearly not adapted to war.

Among the mountains, no one understood why the Dragon Empire had suddenly launched an attack on the mountains.

From top to bottom, from the king of the mountains, the king of the fortresses to the people below who participated in this war, no one knew.

However, they know.

War is such a thing, like mechanical components, like the gears and winches of those huge war machines, the bigger the gear winch, once it rolls down, there is basically no chance to stop until it smashes something or is smashed itself.

In the face of the Shuhai tribe, it was the mountains who chose to smash whom, and now, in front of the dragons of the Dragon Empire, the mountains had no choice.

At night, the dwarven frontier fortress was given a brief respite as the enemy stopped attacking.

The Dwarven Frontier Fortress Legion, removed from the fortress wall in rotation.

But......

Almost one-sided defense.

The high-pressure wind bombs that came from the night, the endless assault on the fortress and the wall, were also stopped, and they almost destroyed the wall between one fortress and the other.

However, judging from all sources, the number of enemies who launched this attack was simply not comparable to the number of enemies that appeared in the Battle of Jukai.

It is not so much that the other side is trying to destroy the border defenses, but rather that the other side is trying to harass or even ...... Training.

With every attack,

Scattered in the various forts, the troops deployed in the rear areas will be called up and converge towards the core fortress of the border wall.

However, when the fortress legions converge, the enemy will retreat.

Soon after, the news of another fortress being attacked will be received.

The tyrant's dragons, the Dragon Empire is harassing, and it is draining the power of the Frontier Fortress Legion.

Even if they launch "Death in the Sky", the enemy temporarily aborts the attack, and soon receives the message that it is being attacked from other directions again.

And the attacks they launched, the elemental bombs they fired through the deployed war machines, did not inflict enough trauma on the enemies who were hiding in the night.

With each counterattack, elemental blasts are consumed at a rate visible to the naked eye, however, what about the enemy?

Don't use Elemental Blast?

Whether it's a grenadier throwing a javelin or a ballista fired from a ballista, it will be dodged and intercepted in the process.

Resources are being consumed.

And......

This group of tyrant dragons who launched an offensive of harassment and attrition.

........

Feeling the increased firepower of the dwarven fortress, the Feathered Dragons directly chose to retreat.

A large number of feathered dragons, with pitch-black figures, flapped their two pairs of wings, and withdrew into the distance in a scattered formation, separating from the left and right directions, preparing to mix with the other feathered dragon troops.

In the dense forest, the pterodactyls that spewed spit scaly wind bombs also withdrew from the burning dense forest in the staggered movements of their limbs and claws.

As the commander of the harassment attack, the combined team composed of Lepids and Feathered Dragons actually knew very well that the range of the dwarven weapons was actually longer than that of the Feathered Wyvern.

However, the Feathered Dragons are able to fly quickly through the air, and there are Feathered Wyverns who specialize in watching for attacks.

High in the sky, there are also poisonous feather flying dragons throwing poisonous plumes downward and spitting poisonous mist.

The dwarves knew that the dragons were meant to consume and harass, and the dragons understood what the dwarves had in mind.

The biggest drawback of the dragon herd is the numbers.

As long as a single attack can kill more than five Wyverns, the offensive of the "Tyrant" dragon group will naturally decline.

The dwarves did shoot down a few wyverns.

However, these days, the total number of dragons killed in the Wyvern group is only 3.

Those seriously injured wyverns will be quickly transferred, kept alive under the treatment of Lepidopterans, and then ......

Blessed with the crown, after a few days, their injuries will heal, not only recover, but also become stronger.

And the opposite is ......

The dwarven frontier fortress has been destroyed thirteen by the Wyverns.

Although the dwarves will soon appear in the location of the destroyed fortress in the field of war machines to fill the defensive line, the dead dwarves are indeed consumed.

In the face of the Wyvern troops, which can quickly move and have powerful long-range attack methods, it is difficult for the dwarves to make effective and substantive counterattacks under the attack of the poisonous mist.

And as soon as daylight comes, the enemy stops attacking.

However, the dwarves did not dare to relax.

Once lost, the tyrant's dragons will surely drive straight in, occupy this high ground, and use this high ground as a starting point to wreak havoc in the kingdom of the mountains.

......

In a border fortress to the southeast, a group of dwarven legion commanders are struggling to make decisions.

"We should move more troops to the second line of defense! We can't keep up with the speed of the Tyrant's Wings. ”

A legion commander slapped the table with some excitement.

Tyrant's Wings is the dwarven name for those Storm Wyvern troops.

This force, which had never been heard of and never mentioned in intelligence about the Dragon Empire, was undoubtedly the most difficult enemy for the Frontier Fortress to deal with.

However, as he made this request, another dwarven commander responded:

"The Southern Frontier Legion has already suffered this loss!"

"The Southern Frontier Corps transferred the corps units on the third and fourth lines of defense, and even the war machinery, to the second line of defense, and then?"

"And then those fortresses that have been transferred out of the troops, will be attacked!"

"Wyverns are able to pass through our defenses from the sky and launch direct attacks on our inner fortresses, cities! The enemy does not walk on the ground! ”

"They're even attacking factories that make war machines and where elemental bombs are stored!"

"Three armories have already been attacked by Tyrant Wings! When we come to our aid, they immediately choose to leave the battle and do not engage us directly at all. ”

The dwarven commander also slapped the table.

The dwarven commander was completely incapable of understanding the enemy's tactics.

Is the enemy intending to wage war with them for months?

Historically, excluding the war at the time of the founding of the Mountains, the longest war experienced by the Kingdom of the Mountains lasted less than five months.

Indeed, the Dragon Empire is powerful.

However, the tactic of attrition is the last thing that the Dragon Empire should use.

The Wyverns of the "Tyrant's Wings", it can be confirmed that each one has at least eight levels or more......

Even if it's just a storm wurm or a storm wyvern, how many years does it take for such a powerful dragon to grow?
