"Iron Soldier City" is still the core of the "Fortress on which the Sun Never Sets", and the three giant magic crystal cannons can cause great damage to the Demon King Army every time they are fired, of course, the defense means of the "Iron Soldier City" are not only this, this is a real iron bucket-like walled city, and the three giant magic crystal cannons are just more conspicuous fangs.

The most obvious thing is that there are already many garrisons on the city walls in other places fighting with the demons, and from time to time there are various attacks from the demon king army below, only the "Iron Soldier City" has been impregnable, and no one can jump into the thunder pool.

Even one of the dragons who had been staying here failed to climb the walls of the "Iron Soldier City", so they had to turn their spearhead to the walls in other locations.

But just after the giant magic crystal cannon destroyed the tower of the Demon King Army, a figure rushed straight towards the "Iron Soldier City".

This is also a giant dragon soaring in the air, but this giant dragon is covered in dark scales, and its size and momentum are much stronger than the previous dragons, just staring at those violent eyes has a feeling of despair.

Dark Flame Dragon Andula, this is the strongest dragon except Andrew, although defeated by Arthur's sword, but Arthur is already the number one sword saint in this continent, Andula relies on the natural body of the dragon clan, and is afraid that there is no opponent under the "demigod".

He's been waiting for a long time, this guy may be one of the few people who enjoy the war, and finally can't bear to make a move.

Andura didn't even use the dragon flame, so it hit it hard, the dark flame dragon was originally a dragon with strong defense, although it was not as good as its eldest brother crystal dragon, which was known as the first defense in the demon world, but it should not be underestimated.

"Boom" There was a loud bang, in the face of such a physical attack, the role that the linkage magic array could play was very limited, and the "Iron Soldier City", which had experienced a year of war and had no damage, actually collapsed a corner, and a gap appeared.

Andula frowned and looked at the small gap, obviously not very satisfied with the power of this collision, this "Iron Soldier City" did not know what material it was made of, it was so strong?

Andura's gaze fell on the giant magic crystal cannon closest to him, which had been loaded at this time, and the siege vehicle aimed at the demon king's army was about to be launched.

Seeing Andura's gaze turned, the magician in charge of the command was also very courageous, and yelled: "Leave him alone, hurry up and launch!"

This commander is very wise, if even the "Iron Soldier City" is restrained by these dragons, then there is really no way to deal with the gradually approaching siege weapons of the Demon King Army, and now the overall battlefield is still the advantage of human beings, but if the Demon King Army below is allowed to climb the city wall, it is difficult to say.

The barrel of the giant crystal cannon began to glow brightly, and the power of a giant magic crystal placed on the barrel behind the magic crystal cannon was quickly drained, and all of them were gathered in the barrel of the magic crystal cannon.

Andula roared angrily, her two huge wings flapped one by one, and she stretched out her claws to grab the glowing barrel, and wanted to launch the magic crystal cannon in front of him, didn't it make it clear that she looked down on him.

But between Andula and the Crystal Cannon, two figures suddenly rushed out, they were two people who looked very similar, they were twins at first glance, both of them were holding a sword that shimmered with cyan light in their hands, and the two swords were in front of Andura's claws.

With a piercing tearing sound, the two swords actually blocked Andura's claws and blocked them back.

Andula let out a light "huh", two sword saints!

And the exercises practiced by these two people are very special, if they are just ordinary two sword saints, they may not be able to block Andura's claws, but there is some mysterious connection between the two swords of these two people, and they can be combined to meet the enemy.

There are still many powerful people among human beings.

Even so, the bodies of the two men flew upside down and fell to the ground one after another in the air, both of them snorted, and their movements were surprisingly consistent, and if you looked closely, you could see that the brick that the two of them stepped on and the ground around them had completely turned into powder.

Although the two of them use swords, they are practicing feminine exercises, and they have always been invincible against power-type opponents, but today they were deflated, the power of this dark flame dragon is simply terrifying, beyond the limits that humans can imagine.

But that delay was enough, and the giant crystal cannon was fully charged, and the huge crystal cannonball finally left the chamber and fired.

Andula snorted angrily, with wings behind him, although his body was huge, his speed was not absolutely slow, and his body flew backwards for a distance, and a mouthful of dragon flame erupted.

Andura's Dragon Flame is completely different from other dragons, his Dragon Flame is much more "stingy", and the coverage is very narrow, it is a narrow pillar of fire.

But this pillar of fire is completely black, the name of the Dark Flame Dragon is not called for nothing, and Andula has his own peculiar black flame fire.

This pillar of fire collided head-on with the burst of magic crystal cannonballs, and the huge power of the two erupted in the air, making it look like fireworks from a distance.

But after all, it was Andura's Dark Flame that was superior, and the huge magic crystal cannonball was actually ignited by this dark flame, and finally disappeared completely in the air.

However, the dark flames of Andula did not disappear, and still fell on the walls of the "Iron Soldier City".

Andula was aiming at the giant magic crystal cannon that fired the magic crystal cannonball, and this magic crystal cannon didn't know what material it was made of, even if the dragon just now sprayed dragon flames, there was no way to take this magic crystal cannon.

Each Giant Magic Crystal Cannon is a huge help to mankind, and the hardest materials are absolutely used up in the casting of the Giant Magic Crystal Cannon.

Speaking of which, if the material is not strong enough, the giant magic crystal cannon will not be able to withstand the large amount of energy that has been accumulated.

Andura's black flame fell on the giant magic crystal cannon, and the surrounding humans evaporated as soon as they came into contact with this black flame, but this magic crystal cannon actually didn't melt immediately.

But Andurah had no intention of stopping the dragon flames, and the continuous black flames fell on the giant magic crystal cannon, and finally reached the limit of the magic crystal cannon, and the body of the magic crystal cannon gradually melted into a puddle of molten iron......

By the time Andura stopped spraying the dragon flame, the magic crystal cannon had already melted most of it, and with the disappearance of the dragon flame, the molten iron also solidified again, in short, this magic crystal cannon was completely scrapped.

Andula raised his head to the sky and roared, and his crazy voice resounded throughout the "Iron Soldier City": "Stupid humans, surrender to me!"
