With some demon king armies climbing the city wall, this war has become more intense, and at this time, the linkage defense magic array has not been fully charged, and the defense of the city wall has indeed declined during this time.

The result of this is that the artillery fire from the rear of the Demon King Army that has been continuing has finally worked, and the fighting method of the Demon King Army is different from that of humans, in addition to the cultivation of their own strength, human beings also rely on various props, such as giant crossbows and magic crystal cannons all over the city walls, etc., all kinds of suppressive firepower are of course more than these, and there are also various weapons like catapults.

But the Demon King Army is different, compared to the tools, they obviously believe in their own strength, in addition to the giant tower and simple and violent weapons such as the battering ram, they still rely more on the demon's own physical advantages.

For example, the giant toad that appeared in the distance, this thing has also appeared in the "Iron Soldier City", but this one is obviously much larger, and the tumor on the surface of the body seems to be surging like breathing, and after charging, it can be launched like a cannonball, and its power can easily destroy the walls of a small city.

There are many monsters like this, these are the heavy firepower of the Demon King Army, if it was placed in the past, these heavy firepower are an extremely important part of the war, not only can destroy the city wall, but also suppress the human army on the city wall, covering the Demon King Army to approach the city to carry out siege warfare, it is simply invincible, after all, these mobile batteries are stronger than the human magic crystal cannon or something, I don't know where it went

But obviously this point has long been in Josephine's plan, the "Day Don't Fortress" is indeed powerful, but the shortcomings are also obvious, after all, it is a fortress, there is no way to move, and all attacks can only be passively endured.

If it's just a short war, but this war is destined to last for a long time, then obviously it can't be fought by the Demon King Army using the "Fortress Where the Sun Never Sets" as a target.

This is the necessity of the existence of the linkage defense magic array, this war can last so long because of the role of this linkage magic array, this magic array can make the heavy firepower of the demon king army almost ineffective, greatly increasing the difficulty of siege.

If the fortress walls are to protect the skin of human beings, then the linkage magic array is one of the more important meridian systems.

In the early days of the war, this linkage magic array can be regarded as a big loss for the demon king army, and there is no good solution until now, but one thing is certain, we must find a way to destroy the linkage magic array, or we will not be able to capture this fortress at all.

At the beginning, the surprise attack force led by Yaheng was for this purpose, although it was impossible to directly destroy the linkage magic, but every time a crystal was destroyed, the defense of the linkage magic array would decrease.

Yaheng and the dragon's attacks destroyed a lot of magic crystals, coupled with the excessive power used by the "Silver Light City" when he released that blow, the power of the magic array was significantly reduced, and the heavy firepower of the demon king army could penetrate the magic array and fall on the walls of the fortress from time to time.

This made the already busy human defenders even more chaotic, they had to watch out for ghosts and gargoyles that would come out of nowhere, and they had to deal with the demon army that ran up the city wall from time to time.

In such a panic, it was the old man who first noticed that something was wrong, and Yaheng had been entangled by adventurers on the human side, and the old man had time to look at the overall situation.

Wrong...... The old man kept looking in one direction, and suddenly pulled a good magician over: "That direction! Cast a true vision magic in that direction!"

The magician was stunned for a moment, smashed a swooping gargoyle with a fireball, and then waved his staff to point in that direction, his strength was still very good, and he also trusted the old man.

"True Eye!"

This is a low-level but very practical magic, which can see invisible monsters and see through illusions.

A ball of light rises, the shape of a pupil that is always visible.

There was a distortion of the space-time below, and it was obvious that there was an illusion in that position, and under the light of the True Eye, this illusion was also cracked, and everyone was shocked.

Shrouded in that illusion is a siege engine!

This kind of special siege vehicle is very heavy and huge, and the dragon head made of pure iron will come directly to the city wall, and even the wall of the "day fortress" may be dangerous.

But on the other hand, such siege vehicles are too bulky, and it is easy to become the object of fire, and it has been so long since the war began, and such siege vehicles have not approached the city wall several times, and this time the Demon King Army has also learned to be smart and began to play yin.

This siege vehicle was the first one of the Demon King's army, and now it is also the closest one to the city wall, with a distance of less than 100 meters left.

There were more than a dozen siege vehicles on the battlefield, but most of them were still four or five hundred meters away from the city wall, and they were struggling under the special care of various long-range weapons on the city wall, which also gave the human defenders a false impression, as if these siege vehicles were not threatening in a short time.

What they didn't expect was that the demons actually used illusion to hide a siege vehicle, with the size of the siege vehicle, it was not easy to hide it with illusion, and the demon king army also put in a lot of effort, but from the results, it was undoubtedly successful, this siege vehicle was found very close to the city wall.

The old man was also taken aback, and suddenly roared: "Aim at that siege vehicle for me!"

If you really let this siege vehicle get close to the city wall, everything will be over, although there are bone towers erected in several places, and some demon king troops rush to the city wall to fight with the human defenders, but on the whole, it seems that humans still have the advantage, and after all, it is the appearance of humans on the city wall, and it will not collapse.

But the siege vehicle is different, this thing can directly knock the city wall out of the hole, if the wall of the fortress collapses, even if it is just a small gap, the demon king army will continue to pour in, then the human race can't even occupy the geographical advantage, how to block the army that is eyeing outside!

Humans know this truth, and of course the demons also know that as long as a hole is opened in this city wall, the balance of this war should begin to tilt, and the most important thing is that now the linkage magic array is in a weak period, which is simply a godsend.

The demon king army below also completely ignored the firepower pouring down from above, and desperately moved the siege vehicle under the rain of swords.

Seeing that the siege engines were still getting closer and closer to the city walls......
