Originally, according to Lin Yun's estimate, half an hour was the limit of a fortress from the beginning of its appearance here to its complete stability, but now it seems that he has completely underestimated the strength that the mages of Northrend can burst out after uniting.

From the beginning of this fortress to this way, all the steps and time have been calculated, and when the fortress arrives here, the battlefield on the front line has already advanced exactly five hundred kilometers.

It only took ten minutes from the time the fortress arrived here to the time it was completely completed!

In ten minutes, this fortress was no longer in charge, and these crazy guys, in order to ensure that this fortress node would not have a bad impact on the future six-pointed star array, directly turned the land here within a radius of more than ten kilometers into a mage version of reinforced concrete......

With the passage of time, this range will continue to grow, or in ten days, this fortress will be connected to another fortress dozens of kilometers away, and the range of this huge mage version of reinforced concrete will be instantly guaranteed to a range of tens of kilometers......

After all the aura of this fortress was linked, Lin Yun felt a little drunk when he thought about it......

This group of bastards really wants to do things absolutely well, and the land with a range of thousands of kilometers will be turned into a huge piece of mage version of reinforced concrete, and the depth will extend to at least three thousand meters at that time......

Coupled with the power of the super-large range of six-pointed star arrays, this passage space will really become a Jedi with no grass, and the entire space will become a complete mage version of reinforced concrete, and when the time comes, a divine fire mage, don't want to destroy any steel fortress, if you want to destroy any steel fortress, you must completely destroy the entire passage space.

This is tens of thousands of times more difficult than directly destroying a territory with a range of thousands of kilometers, and only the power of gods and demons can do it......

When I was chatting with Agaron and Alonzo before, I casually mentioned an idea, and these two guys extended the idea at that time to the extreme, completely to the extreme.

But at present, this is indeed the best way, and Lin Yun can't think of a safer way. After glancing back, Lin Yun was sure that the steel fortresses in the rear were all operating in this way. Finally, if nothing else, the transformation has now been completed, and the passage to the Leviathan plane has been blocked, even if it fails now. The undead don't want to rush into the Leviathan plane.

The worst-case scenario is just to maintain the status quo......

After another ten minutes, Lin Yun felt that this piece of steel fortress, as part of the six-pointed star array, had been activated, and the power of the formation had begun to emerge, the chaotic magic fluctuations here had been forcibly suppressed, and the aura had become normal, and the battlefield on the front line was like being isolated.

Twenty minutes, the territory occupied by this side of the Northrend world. Again expanded to a depth of five hundred kilometers, these places, after being occupied, could no longer be taken away.

A perfect masterpiece, this kind of efficiency, Lin Yun can't pick out any thorns, now he only needs to follow the established way, little by little, to drive those undead out of this passage space, at that time. The arrangement of the six-pointed star circle has already been completed, and the six-pointed star circle is activated part by part, first blocking the army of the undead, and finally the six holy alchemists will completely activate the whole of the six-pointed star circle together. This matter can be considered completely solved.

Lin Yun followed Gandalf, floating at an altitude of three thousand meters, watching the fierce battles on the frontline battlefield, the magic crystal cannon, the large-scale spells released by the joint, and the magic energy battleship......

The firepower piled up together, and in just half an hour, it crushed the undead for hundreds of kilometers. Crush most of the undead in this range to death, and suppress the spread of the sea of undead.

When the suppression passed, the transport team carrying the steel fortress in the rear was already waiting, and most of them were pressed forward.

After the strongest firepower was suppressed all the way, there were a large number of weaker mages, swordsmen, and alchemy puppets in the rear, who together killed all the remaining undead to ensure that there would be no mistakes when arranging the steel fortress in the back.

And by the time the firepower of the frantic assault on the front line weakened a little, and the undead began to strengthen their forces to counterattack, the steel fortress in the rear had already been arranged.

Activate the phased magic circle, first have a part of the power to suppress and resist, and then rely on the fortress, and retreat a little to the frontline team, you can easily resist the counterattack of the undead.

Slowly harvest the undead, reduce the number of the undead sea, and when the scale of the undead sea in front of you is no longer so strong, the mages in the rear have almost recovered, and once again gather the strongest firepower, continue to roll and impact......

It's just a cycle of repeating itself again and again, and if it doesn't work, keep coming again, moving forward little by little, this is the best way at the moment, because there is no need for a super strong person to make a move, and a strong person below the fifth level of the Heavenly Rank is enough to control this situation.

On the undead side, there are only occasionally undead lords above level forty-five who appear on the front line in person, and the undead lords who can appear like this only mean one thing, that is, the undead soldiers under his command are about to be completely lost.

The undead are more brain-dead in this place, from the beginning of the war to the end of the war, more than ninety percent of the time, where is the cannon fodder of the sea of the undead, where is the continuous consumption, countless undead fighting and dying, the undead lord will basically not appear, only when the war is about to end, the two undead lords will appear.

If there is no great hatred, then the war is like gathering soul fire for everyone, and maybe after the war is over, two powerful undead will appear under your hands.

If there is a deep hatred, either you die or I die, then it is even simpler, two undead lords fight each other, and only one can survive in the end, whoever wins, who will devour the soul fire of the losing war lord, even if the injury is serious, as long as you win in the end, then after devouring the soul fire, all injuries can be recovered, and even the level will be increased a little.

Now that they are fighting against the coalition forces of the Northrend world, the undead creatures are still fighting according to this pattern, so the Northrend coalition forces have this advantage.

Gandalf looked into the distance, a battle line that looked like a chaotic aurora that stretched for thousands of kilometers, a magical light formed by the glow of the spell.

"Merlin, I always felt that something was not quite right, maybe there was some conspiracy on the undead's side, since we came back, everything has gone so well, it has gone unbelievably well.

Those undead lords seem to be crazy, and they are still fighting infighting, and the infighting is getting worse and worse, and more importantly, what these guys are grabbing now is not the territory of the Dirty Blood Territory, but the territory outside the Dirty Blood Territory.

According to the news that came out before, it seems that the forty-seventh level undead lord has been killed in the infighting......"

Gandalf looked worried, because this situation is too abnormal, if these undead can cooperate well, every undead lord will attack the territory occupied by the Northrend coalition army, it is very difficult to resist here, and if you want to encroach on the territory little by little according to the current strategy, the difficulty will increase at least dozens of times.

Now three or four impacts, you can almost advance out a distance of hundreds of kilometers, at least a distance of thousands of kilometers a month, and it is completely occupied and the steel fortress is arranged.

According to previous estimates, being able to advance 1,000 kilometers in three months is considered the best result in the prediction, but the actual situation is several times smoother than the smoothest situation in the prediction, which is a bit abnormal......

Lin Yun shook his head, he didn't pay much attention to this, and before he listened to Gandalf's words, Lin Yun knew that this must have been made by Yimir.

This guy's hatred for the mourning bird can definitely drive him to do anything, since Yimir can release the flames and burn the mourning bird himself, whatever Lin Yun says, Yimir will take it as the truth.

Before, I let Imir stir up the situation, just to provoke the infighting of the undead, these undead lords are not the kind of creatures that can unite, they are all for their own interests, and **naked in order to pursue their own interests, there is no possibility of union, as long as someone and an undead lord provoke a war, it is easy to spread the scope of the war.

I just didn't want Ymir, a simple dwarf ghoul, to rush to the front line so stupidly, and then be killed by the Northrend coalition army, after all, Ymir also helped him a lot, everyone's position and race are hostile, but it's not the kind of race that must be exterminated until both races must be exterminated......

As long as this passage space is cut off and sealed, no one will be in the way of the other party in the future, and there will be no contact at all.

Flickered Emir retreated and withdrew from the battle of the Stained Blood Territory, so that no matter how it develops in the future, the war with the Northrend coalition army will not come together, but I didn't expect Imir to help a lot again, stirring the rear of the undead into a pot of porridge, and the war in the rear is even more fierce than that of the Dirty Blood Territory.

It is precisely because of this that the strategy of the Northrend coalition can be so fast and so smooth in close combat.

Lin Yun was originally not going to tell anyone about Yimir, but seeing Gandalf's worried look, he seemed to have the idea of going deep into the undead plane to find out the truth, so Lin Yun briefly said these things.

He uses the power of the Chapter of the Dead, disguised as an undead, fools a ghoul lord, and provokes infighting behind the back of the army of the undead......

Lin Yun didn't say it too clearly, but Gandalf understood, shook his head with a smile, and didn't say anything.

After a few days of wandering around this passage space, he found that there was nothing he had to do now, everything here was working normally, as long as he prepared the activation of the six-pointed star array, there was no problem with this.

This super-large six-pointed star magic circle, the most untechnical is the final all-round activation, which only needs the six holy alchemists to personally take action and use the power of creation to activate it. (To be continued.) )
