At that time, the fortress was still being designed, but here in the Old Continent, a very mature fortress design system had been in place for many years.

A large number of mature fortress designs are piled up in the warehouses of various empires, and even some places have become moldy.

The type of fortress suitable for Feng Zhan's territory was quickly selected. It was a super-large fortress used to resist demon attacks hundreds of thousands of years ago. After tens of thousands of years of continuous improvement, it formed hundreds of layers of fortresses.

The terrifying scale of city walls, even thousands of walls.

The complex layout and exquisite structural design are enough to cope with the only gap that appears.

Moreover, two such fortresses were prepared, one inside and one outside, in order to avoid accidents as much as possible.

After receiving such inside information, those legendary magicians immediately began to use their connections to operate.

They are still obsessed with the alternative skills they designed and reproduced, even after hundreds of years have passed.

Even if a few of them are traveling in the void and exploring, they will still contact other friends through the magic circle. They must complete their skills and let this skill reappear in the world.

They originally had the opportunity to compete for the design of some magic arrays in the fortresses in the New World. Perhaps it would not be a problem to embed their magic arrays in them.

But the scale of the war exceeded everyone's imagination. The number of monsters there could no longer be described as terrifying, and it was almost as if they were filling the entire world.

For this reason, smaller magic circles are not suitable for fortresses in the New World.

Even their magic circle seems a bit small, not enough to gain a foothold in the New World, and that magic circle has no actual combat experience at all, which makes people very uneasy. Even the work of a legendary magician is not good enough.

It is not easy to gain trust, especially in the face of such a war that affects the survival of the entire world.

So their ideas were once again strangled in the cradle.

However, these guys are like old men who are obsessed with their magic circle.

Even if the large forward bases in the New World cannot use their magic circles, some small fortresses or forward bases can still be fought for.

It's just that they didn't succeed for a long time, but faced with the only possibility, they were not willing to give up easily.

While they were still working hard to promote their magic circle, Feng Zhan's territory gave them great hope.

At that time, no one was optimistic about the fortress. Even at the beginning, whether the fortress should be built was a matter of great controversy.

After all, in the early days when the monster's teleportation pillar appeared, the Old Continent could be said to be in a defenseless state, and it was still a newly established territory.

Everyone knows that the attack power of monsters is extremely terrifying, especially their terrifying number, which makes people's scalp numb.

But who would have thought that as soon as the monster appeared, it would be discovered by the scouts of Feng Zhan Territory, and a collision would occur from the very beginning.

Miraculously, he actually won. That was when he collided with monsters in a field battle before the fortress was even established.

Although it had the right time, place, and people, speaking of Feng Zhan's territory, not many warriors appeared there at the first time, but they were still able to resist their reinforcements before they arrived.

What's even more surprising is that it is a place that is focused on by the will of the world. The moment the monster's teleportation pillar appears, it directly suppresses the monster's power.

A space barrier was even built there, directly blocking the entire mountain where the monsters were located, so that no monster could leave there.

Except for the gap that was deliberately left, it has been completely sealed.

As long as they can guard that exit, no monster can escape alive.

Since this is the case, it is extremely necessary to build a fortress with extremely strong defensive attributes here.

Naturally, a fortress with hundreds or thousands of walls became the best choice. Originally, the main magic circle that was supposed to be laid out was a defensive magic shield, but under the operation of those legendary mages.

They spent a huge price to directly replace the magic circle they had laid out with their own rainbow. It was extremely incredible. Originally a defensive fortress, the most important thing was defense, and offense was secondary.

But their dedication to this rainbow magic circle has been deeply rooted in their bones. If they can't see it take shape in their lifetime, I'm afraid they won't be willing to die in this life.

Of course, such a replacement is not a simple matter, and requires deep involvement in the modification and reconstruction of the fortress. Otherwise, it will involve shooting problems in all aspects of the fortress, and the change cannot be completed overnight.

Otherwise, once the magic circle of a fortress is changed at will, the defense effect of the fortress will probably become very poor.

Although they are extremely persistent in their magic circle, they do not want to destroy the fortress.

The magic circle that can change the fortress is so that it can have a real chance to perform and shine when fighting the enemy.

Therefore, more than a dozen of their legendary magicians spent a lot of energy to transform the fortress, and finally reached the point where their magic circle and the fortress were almost perfectly integrated.

And since the construction of that fortress began, he invested a lot of precious materials. After all, replacing the magic circle there does not come without any cost.

If they cannot invest enough materials, the southern countries may not agree.

It's just that in the many years since this magic circle was established, no matter how the monsters attacked, the top officer of this fortress, Feng Huo, was never willing to use it.

This was something they couldn't understand, because the materials consumed by this magic circle were extremely staggering, and the requirements for magicians were also very high, but they had provided this fortress with enough materials to be used ten times.

Even if the top commander of this fortress is stingy, using it once shouldn't be a big problem.

But no matter how they waited, or even when they personally came forward to persuade the other party that they could use it once at certain moments they considered important, they remained indifferent.

If it weren't for the fact that the other party's identity was something they couldn't change at will, they would have picked up their own magic wands and fought against the other party.

The malicious intent of a dozen legendary magicians would make even Feng Huo sweat on his forehead.

However, Feng Huo still endured it, and remained indifferent no matter whether the other party was threatening or tempting him. That was the true feeling of not being surprised when Mount Tai collapsed.

However, Fenghuo didn't do nothing. When he built this fortress, he already knew about the existence of this magic circle.

Knowing that those legendary magicians put countless efforts into it, the power should not be small. Besides, if the things made by more than a dozen legendary magicians are not of a certain standard, there is no way to show them off.

They have been urging themselves for so many years, just like farmers waiting for the banker to mature. The seeds have been planted, autumn has arrived, and they are waiting for harvest.

But he didn't even use his sickle. Wouldn't that make these old guys anxious?

The previous battles had been carried out step by step. The enemy was attacking and I was defending. Sometimes I would send out legions to attack the monsters proactively.

So many years have passed between you and me, and not much has changed.

But until before, when he sent out an army to attack, he had determined that the time had come.

That is to send a false message to the monsters while sacrificing some people, making them think that there is enough opportunity to attack the Iron Wall Fortress, and they can successfully break through it after suffering a certain amount of losses.33

Although this is not a merciful decision, there are always people who have to sacrifice for the safety of the entire world. The only thing that makes people feel at ease is that they have to take good care of their families and future generations.

We cannot let those brothers who sacrificed their lives bleed and shed tears.

Although Feng Huo has already transmitted the information he wants to convey to the other party to the brain demon.

But if you want the other party to make up your mind, there are still a lot of things to do.

But Feng Huo has great confidence in the other party's determination. The monsters did not come to this world just to slowly waste time with them.

If we cannot break this fortress and rush to the old continent, the monsters that come here, especially that monster, will definitely face extremely terrible consequences.

In the New World, he has seen too many failed monsters. What kind of fate will they face? Being killed is already a light thing. In serious cases, the entire tribe will be killed and completely exterminated.

Even some related ethnic groups will be killed together. In the tragic world of monsters, there is no warmth at all. Clear rewards and punishments may be a milder statement.

Brain Demon really lived up to Feng Huo's expectations. No matter what the specific reason was, Brain Demon took action.

It can no longer wait any longer. This is a completely isolated world. If they don't leave through the only exit guarded by the iron wall fortress, these guys will die here.

If they don't leave, it will be no different than death. After all, they are here to invade and destroy the world of Esgaia. What on earth is the point of staying in such a small space?

When the army of monsters and monsters were all gone, and they came overwhelmingly to kill, Feng Huo knew that the time was finally right.

Unlike those legendary mages who only want to test their magic circles, as someone who has been on the battlefield for decades, he naturally understands what it means to make a decision and then act. Only when the time is right, can

The real critical moment.

After completing a large amount of preliminary layout, the war went very smoothly. Although the monsters' attack was very fierce, it only looked very fierce.

Because when this fortress was first established, Fenghuo placed a large number of illusion magic arrays in it, which could directly guide the enemy's spirit to produce hallucinations and trances.

In the face of such a large magic circle that spreads throughout the entire fortress, no monster can be spared.

Countless monsters are trapped in the illusion that they are about to break through the Iron Wall Fortress. However, war always kills people. It is impossible for him to hide all the legions in the Iron Wall Fortress. Only real blood can deepen the monsters' power.

Cognition makes them indistinguishable between false and true.

Therefore, none of the legions blocking the monsters are fake. The only difference is that there are a large number of legions that can be rotated, instead of all the legions working together at the forefront to engage in a true life-and-death fight with the monsters.

Of course, the losses of each legion are not small.
