Even if he is a Divine Fire powerhouse, when facing the suppression of the power of a world, he can only protect himself at most, and he may not even be able to protect himself.

As long as the natural half-plane is developed well, so that the development of the natural half-plane can be carried out smoothly and there will be no deviation, then there will not be much problem.

Leaving the natural half-plane, he instantly felt that the magic around him became irritable, flew into the air and looked around, and found that all the people in the fortress were in a hurry, and there were constantly mages falling into the fortress in the sky, and people were constantly flying out of the fortress, and in the direction of the front line, the sky had changed color, and the black clouds turned into a huge whirlpool.

The brilliance of the spells continued to light up there, stretching for thousands of kilometers, and it was impossible to see the real battle situation, just by seeing the brilliance of these spells, you knew how fierce the battle situation on the front line was.

Thousands of kilometers of display, but there is no magic fluctuation here, and there is even a feeling that the battlefield on the front line is very far away from here, when he saw the fortresses in front of the fortress with a little metallic luster, Lin Yun suddenly understood.

Agaron and Alonzo have done what they said before, and the new fortress looks half smaller, but it is definitely much stronger than the fortress that the mage built with the help of spells.

These fortresses are all made of steel and magic iron, and then carved dense magic patterns and runes on them, so that the entire fortress is a whole, and with a little magic crystal and other things, it can almost be regarded as a relatively cumbersome magic fortress.

This is only the fortress's ability to protect against war, and the fortress, as an important node of this super-large six-pointed star array, plays a stronger role than the previous fortress.

I don't feel too much magic fluctuation here, because the phased magic circle composed of these fortress nodes has begun to activate and advance little by little.

These days have advanced a distance of thousands of kilometers, and the sea of fire that originally crossed the center of this passage is about to be completely extinguished. The Northrend coalition has also crossed this sea of fire, completely occupying the land where the original sea of fire was located, and steel fortresses of different shapes have taken root here.

Lin Yun flew out of the fortress under his feet and flew towards the front line. Before reaching the front line, I saw six floating fortresses, dragging a steel fortress towards the front line.

The steel fortress was less than two kilometers in diameter and shaped like a hemisphere with a missing horn, only the top half of the ball. The lower part is a flat plane, and at the lower end of the plane, there are six steel spikes hundreds of meters long.

These spikes were all made of magic iron mixed with other magic metals, and they were covered with dense alchemy patterns, and with a little glance, Lin Yun could guess the effect of these metal spikes.

When this steel fortress falls to the ground, the six spikes hundreds of meters long under the fortress will pierce into the earth, and after the fortress is completely stabilized, the alchemy circle arranged in advance on the six spikes will be activated. Coupled with the control of other mages, these six spikes can change shapes, so that the fortress can grasp the earth to the death, and the land within a radius of at least five kilometers around it will be caught, and no one can move the position of the fortress, nor can the fortress be grabbed again......

And on the flat plane at the bottom of the fortress, there are also dense alchemy patterns, magic patterns, inscriptions, and runes......

The combination has a special ability, so that after the fortress and the earth come into contact, it can no longer move, and the leylines are linked to the magic circle, so that the fortress and the earth's movement are linked together. Become a part of the earth, unless the land completely collapses, otherwise the fortress will not have problems, at least as a node of the six-pointed star circle. There will never be a problem.

Coupled with the power of the earth itself, the fortress's protection will be increased by one level again......

Lin Yun didn't rush to the front line anymore, but continued to move forward with the team that transported the steel fortress.

Around this fortress, there are at least five layers of defensive circles arranged within a radius of hundreds of kilometers, and it is basically impossible for those undead to destroy it. Not to mention the small battlefields closest to this fortress, all of which are five hundred kilometers away.

The floating fortress holding this steel fortress should be the masterpiece of the Sky City, but with the construction of this fortress, Lin Yun saw traces of seven or eight other forces.

As this fortress flew a distance of hundreds of kilometers, Gandalf was already waiting there, Lin Yun did not come forward to disturb, just watched quietly and helped to keep on guard.

Six floating fortresses dragged the steel fortress down slowly, and Gandalf personally intervened to adjust the direction and position of the fortress.

A flat, mirror-like clearing had been carved out of the ground, and there were even six special markings on the clearing, representing the location of the six steel thorns.

The fortress landed slowly, the steel spikes aimed at the six positions, and then as the floating fortress floated, six thick steel spikes, under the weight of the fortress itself, pierced the ground very easily.

When the fortress was about to completely fall to the ground, the six floating fortresses adjusted their positions and appeared on the side of the steel fortress, dragging the steel fortress down slowly.

With a rumbling sound, the fortress completely fell to the ground, and after falling to the ground and stabilizing, the alchemy circle on the fortress was automatically activated, and the surrounding earth and the fortress were connected, making the bottom of the fortress seem to grow on the ground.

And this connection spreads to a range of more than ten kilometers in a few seconds, and as time goes by, this range will even get larger and larger, and when the surrounding fortresses fall and activate, these fortresses will be connected, and no one can pull a certain fortress out of the ground.

The rock mage rushed up to activate some of the magic circles on the fortress, and a steel mage from the Rodney family also began to activate the alchemy circle prepared in advance, which was activated with the power of steel.

Countless runes appeared in Lin Yun's gaze, and his gaze seemed to have directly seen through the earth, seeing the six steel thorns that went deep into the ground.

In addition to seeing these steel spines, there were also huge steel ingots that had long been buried in the depths of the earth, and the magic patterns carved on the surface of the steel thorns began to operate, and the surface of the six thick steel thorns, like a hedgehog that had exploded, exploded out of smaller spikes.

When the spikes came into contact with the ingots buried deep in the earth, the ingots began to change shape as if they were being controlled, like a metal tree growing deep in the earth.

The six thickest steel thorns are the trunks of the six steel giant trees, and the huge steel ingots buried around them are the nutrients needed for the growth of the iron trees.

Soon, the steel ingots in the depths of the earth slowly disappeared, and the underground of the steel fortress, those steel were like extended roots, expanding to sweep the surrounding area of more than ten kilometers, and the depth was also deepened to four or five hundred meters deep, and the complex steel root system devoured all the steel elements in the earth, plus the steel fortress above the head, and the cooperation of other alchemy arrays.

The earth here has all become harder than stone, and this change is still changing with the passage of time, and Lin Yun is a little shocked to see it.

The mages of Northrend, in the midst of foreign wars, finally began to erupt in the brilliance of the brilliant mage civilization, the cooperation of human beings, and the wisdom of mages, which are vividly displayed here.

This steel fortress, from the beginning of the production to the end of the complete here, all kinds of alchemists are indispensable, alchemists who are good at alchemy circles and magic weapons are indispensable, alchemists who are good at alchemy puppets are also responsible for the construction of some of the components inside, and the alchemy potions that seem to be almost useless are the most important here.

Alchemists who are good at alchemy potions can not only make alchemy potions, but also have the knowledge there, and they can be good at the construction of many magic patterns, inscriptions, and runes, and this steel fortress, if you want to be integrated, what you need most is alchemy potions.

However, not all alchemy potions are for mages, and there are many alchemy potions, all of which have special abilities, such as metal fusion agents, reagent catalysts, and physical property change guidance elixirs......

Alchemy is the science of mage civilization, and it is impossible to completely distinguish one or the other, but everyone usually likes to distinguish what alchemists are good at according to the final results.

In addition to the indispensable alchemist, to build this fortress, you also need fire mages, frost spells to assist in construction, earth mages and even rock mages to activate, and most importantly, steel mages of the Rodney family to assist in activation......

Transportation is also a big problem, and many forces such as Sky Castle are the best at this, so they join the transportation team.

Although Lin Yun said before that Agaron was thrown out of the natural half-plane, it was just saying that, Agalon could do this, and mages of Alonzo, Gandalf, and other levels could do it.

However, there were too many steel fortresses needed here, and it was impossible for them to take care of them one by one, which showed the cooperation of the mages, and the explosive power of the cooperation made Lin Yun a little shocked.

When he saw those expressions of the peak era, Lin Yun felt that that era was an era that belonged to the extreme of the mage's great industry, and the efficiency was outrageous.

Seeing this scene now, Lin Yun suddenly understood that the world of Northrend had begun to accelerate towards the peak unconsciously, and the influence he wanted to see had finally appeared, and those slow mages had finally begun to pursue efficiency.

As long as they see the benefits in the middle, it is impossible to make them slow down in the future...... (To be continued.) )
