Waiting at the door of the metal fortress was indeed Grim's 'old friend', the thunder dragon Ames.

It can be seen that Arms also hid his identity during this trip, not only changed into a human form, but also put on a thick robe to completely cover his body and appearance.

Standing alone in front of the towering bronze walls of the metal fortress, Arms silently looked up as a huge metal creature more than a hundred meters long appeared from the distant sky, and soon reached the top of his head.

The floating giant ship hovered for a moment above the half-metal castle in the middle of the mountain, and with the sound of squeaking gears snapping and rubbing, an entrance suddenly cracked above the metal castle that had been in harmony with the mountain just a moment ago.

The floating giant ship slowly sank into it under Arms's astonished gaze.

From a distance, it was as if the metal monster in the belly of the mountain had swallowed up the floating giant ship in one gulp, which made people feel a sense of shock in their hearts.

Since the steam power stage has been crossed, all the energy consumed inside the metal fortress comes from the magic furnace, so there is no huge boiler and steam engine in the past, and the water vapor as huge as the sea of white clouds.

The huge mountain in front of me has been hollowed out by the metal monster in half, and has been turned into a half-mountain, half-metal fortress. The half of the mountain that Amsu was facing had been completely transformed into a metal wall, and the thickness was staggering.

And more importantly, the metal walls are as smooth as new, and there are hardly any entrances and exits. This leaves Arms unable to break into it even if he wants to, and it seems that there is no other way but to smash the wall.

While Arms was silently thinking, a loud and long dragon groan suddenly sounded from the depths of the Stonetalon Mountains.

Hearing this dragon groan, Ames, who was still calm just now, also became a little anxious.

"Lord Ames, welcome to my territory......!

At some point, Grim was already standing in front of the metal wall, and the metal gate behind him slid to the sides, revealing a huge entrance that was 5 meters high and 10 meters wide. On either side of the gate, there were two rows of tall and mighty metal golems, roughly numbering thirty.

Arms looked back, and with the dragon's good eyesight, he could clearly see the small black dot that suddenly appeared at the end of the distant sky. Although it was still twenty or thirty miles away, Arms could already vaguely sense the surging and mighty aura of the fire element.

It's a fire dragon......

According to its memories, there seems to be only one fire dragon that lives near the Stonetalon Mountains and the Swamp of Sorrows, and that is the powerful dragon lady Felipa entrenched in the castle of Doom.

Damn, it was a powerful fire dragon of the 3rd order, and it had a tyrannical temperament and was extremely aggressive. I can't imagine that these human wizards will provoke this terrible guy as soon as they come here...... Damn damn it, damn it......

Arms cursed madly in his heart.

For a moment, I didn't know if it was the female fire dragon or Grim who it was cursing......

Without being polite to Grim at all, Arms strode into this strange fortress made of all-metal. Looking at this appearance, it seems that it doesn't want to take a picture of the fire dragon girl in the distance.

As soon as he entered it, Arms was stunned by the scene in front of him!

This...... What a castle is this! This ...... It's a scary metal city with a wide area and perfect functions!

The silver-white metal floor stretches endlessly, and the road is flanked by metal warehouses and metal buildings rising from the ground. Criss-crossed, multi-fertangle metal roads lead to any corner of the metal city, and walking on them are terrifying metal magic machines with heavy feet and a strong momentum.

There are often as many as 20 vigilance magic weapons stockpiled at those transportation hubs, and they seem to have differentiated into different types of functional magic weapons based on their appearance and shape. It looks like an eight-clawed spider on the outside, and its disc-shaped metal body is densely covered with beehive-like weird compound eyes.

They stood on both sides of the road, constantly scanning every magic weapon that passed, and strange spectral rays flashed in the honeycomb-like compound eyes, as if there was more than one way to detect them.

In addition to this fixed sentry, a metal eyeball the size of a human head was constantly circling and flying over the metal city. They don't have wings, but they can fly around the sky with just a few vents that glow blue.

Every now and then, they would suddenly hover over a building or magical machine, projecting a wide, illusory green band of light from the belly of the machine beneath them. The metal swept by the light band will instantly become transparent, revealing the items and structures inside in front of the metal eyeballs at a glance.

The city was huge and busy, and full of behemoths of metal, but it was not too noisy or noisy. And the construction machinery that walked on it was either carrying a huge metal box, or holding a large pile of metal ingots or some rare material......

As far as the eye could see, Arms couldn't find half of the hundreds of magic machines and construction machinery in front of him who were lazy or loitering. They seem to be on the go all the time, never knowing how to get tired.

And from them, Arms sensed a powerful spiritual power.

Yes, since stepping into the metal city, Arms can clearly perceive the air here, and every piece of steel and metal here is permeated with an indescribable spiritual ability. It seems that they are all ruled by a powerful mind and will, ruling ......

It's that Tier 3 weird giant brain!

Without much explanation, Ames, who had participated in the battle of the Goblin Plane Steel Capital throughout the whole process, instantly remembered the strange and strange lifeform with a strange shape. That guy's physical combat power is almost zero, but in the control of magical energy and mental ability, he obviously has a power that he can't match.

I didn't expect it to survive the explosion......

Arms was secretly annoyed that he hadn't cut the grass last time, when a loud crash sounded on the thick metal walls behind him, followed by a shrill siren in the metal city.

It seems that the irascible dragon girl has come to 'attack the city'!

With the sound of sirens, this originally quiet and peaceful metal city suddenly changed.

The engineering machines that walked through the metal road in an orderly manner all avoided the sides of the road, and several huge warehouses and metal fortresses near the metal city wall suddenly opened up, and from which swarms of battle magic weapons and huge and exaggerated goblin chariots strode out.

These battle weapons and chariots quickly converged near the metal city wall, forming a battle phalanx, quietly waiting for news.

The attacks on the metal walls were becoming heavier and more frequent.

Knock knock knock......

A dull loud sound echoed over the metal city, and some unstable parts of the sky began to fall from the rocks and stones. However, it did not cause much damage to the metal city.

On the inner side of the metal city wall, at a height of 100 meters above the ground, there are also strange metal buildings. When the metal exterior wall was attacked, countless small cannon ports silently cracked in the metal wall, and the metal building moved forward, probing out the muzzles of the black holes.

Immediately, a huge and incomparable magical energy suddenly teleported from the ground of the metal city, and quickly stretched along the walls of the all-metal structure towards the location of the strange metal building. As the gathered magical energy became more and more massive, the magic energy cannon trembled silently, shooting out terrifying energy rays of astonishing intensity.

What the situation was on the outside, Arms did not know.

However, as the magic energy cannons began to fire, the attacks on the metal exterior wall suddenly stopped, and it seemed that the enemies outside had no time to attack the metal exterior wall, and were busy defending against the terrifying energy attack.

The short battle lasted only a quarter of an hour before it ended.

After another moment, dozens of large and small metal gates suddenly opened, and teams of battle magic machines and construction machinery swarmed out, launching the final assault on the remnants of the enemy in the distance.

Soon, teams of construction machinery lifted, held, and carried one by one the severed limbs, and the bloody dragonmen returned to the city, and then put them in some special cells and prisons one after another.

Although he was disdainful of the strength of these magic weapons, Ames saw all this with a pale face.

This is the Reims plane, and this is the backyard of the mid- and low-level dragon lords!

But seeing this scene in front of him, Ames's heart trembled, but he was terrified.

Once upon a time, dragons were the masters behind the scenes, and the dragonmen were the rightful rulers of the place.

But now, just as the dragonmen easily slaughtered those indigenous tribes, this metal city is also slaughtering those dragonmen with a plan and a purpose.

The predators of the past have become the prey of others!

Such a reincarnation of the world, such a reversal of the scene, really made it a little difficult for Arms to adapt.

Just as Arms felt silent grief for the dragonmen outside, a short and poignant dragon groan suddenly sounded inside the metal city.

Arms turned his head to look and saw a large group of metal golems working in unison to remove a white dragon covered in translucent white scales from the floating giant ship on a towering metal platform.

It was the dragon that suddenly came to its senses and let out a short howl.

Ice Dragon Erentini!

He didn't have to look closely, just from the other party's crystal beautiful ice scale armor, Arms could recognize who this ice dragon was at a glance.

In the Reims plane, this second-order ice dragon Erentini is also a rare dragon beauty.

It's a pity that looking at this situation, it seems that she has fallen into the hands of those wizards.

Arms's face is getting harder and harder to look at!
