As part of the demon king army climbed the city wall, the battle situation suddenly became stalemate, fortunately, these demons who took the lead in climbing the city wall generally did not have a high rank, and the adventurers who participated in the battle with the human soldiers could also suppress them on the edge of the city wall.

Although there is still artillery fire falling among the skeleton soldiers who are building the bone ladder below, there is no doubt that under the control of the giant dragon and these demon king troops who have climbed the city wall, the suppression of the artillery fire has been too weak, and the bone ladder has been built to half of the city wall, and the skeleton soldiers who are not afraid of death are piled up.

Another huge magic crystal cannonball, this is obviously a cannonball fired by the giant magic crystal cannon, but this time the target is not the dragon, although this giant magic crystal cannon also has a certain lethality to the dragon, but the trajectory is too slow, much slower than the ordinary magic crystal cannon.

The entire battlefield can clearly see that the cannonball dragged a long purple flame tail, like a meteor shot out of the "Iron Soldier City", as the first of the three major cities of the "Sun Never Sets Fortress", the firepower of this "Iron Soldier City" is also the most terrifying, there are three giant magic crystal cannons on the city wall.

The target of this cannonball is obviously a giant tower that is moving, this kind of tower specially made by the demons is not the ordinary kind of tower used for attacking, the interior of this tower is like a real tower, there are stairs that curve back and forth, and with the size of this tower, medium and large demons can enter.

As soon as such a tower approached the city wall, a steady stream of demon kings rushed up the city wall from below, which was much more dangerous than the bone tower that the skeleton soldiers were building.

Ordinary weapons are blocked by gargoyles hovering high in the air, but this huge magic crystal cannonball is different, all the gargoyles that stand in front of the cannonball are directly evaporated, and this magic crystal cannonball falls on the front tower impartially.

Although the defensive magic array on the tower shone brightly, it was obviously not enough to block the power of the giant magic crystal cannon, and with a loud "boom", the entire tower was broken off by the waist, and it fell down with a mournful roar, and it is estimated that many demon king troops who couldn't dodge were directly stoned to death.

After all, it was a weapon capable of piercing through the dragon's scale armor, and how could a giant tower support it.

This blow caused a burst of enthusiastic cheers on the "Day Don't Fortress", which was really relieved.

But there is not only one tower of the Demon King Army, there are several towers behind it that are advancing fearlessly.

The cooldown time and aiming difficulty of the giant magic crystal cannon are very high, and dozens of soldiers rushed up to supply the magic crystal cannon that had just been launched, but fortunately, the tower of the demon king army moved very slowly, after all, the body was too bulky, and the time was enough for the giant magic crystal cannon to be reloaded.

At this time, a soldier suddenly shivered coldly, strange, isn't it cold now?

As soon as he looked up, there was a looming figure in front of the soldier, the shadow was obviously transparent, even the head was half missing, and he swung at the soldier with a tattered scythe in his hand.

"Hell!"

A commander next to him slashed at the ghost with a knife, and the big knife directly cut it into two parts, and the ghost let out a terrible scream, and its body fell back sharply, but it did not disappear, but opened its red eyes and glared at the soldier in front of him.

The feeling of coldness became even more obvious, and many soldiers felt a sense of despair in their hearts for no reason.

"Don't be affected! these are also the Demon King's Army!"

The commander obviously knew better, and roared hoarsely, but there were still some soldiers around him who were confused and obviously distracted.

At some point, a cloudy mist spread from the direction of the Demon King's army towards the "Sun Don't Fortress", and now it has completely enveloped the entire city wall.

There were many looming figures in these fogs, and as long as they were entangled, many soldiers suddenly lost the courage to fight, and they wanted to flee immediately.

These fogs are naturally the kind of fog in the area where the "Nightmare" is located, of course, the fog here is much weaker than his there, and the black fog that appears with these "soul bodies", in human terms, ghosts.

Most of the ghosts' combat power is not very good, after all, they don't have a physical body, and their cultivation almost all hits the spiritual side.

The most obvious thing is that when such a large-scale dispatch is made, even if you don't deliberately use any soul attack skills, it will give people a sense of despair from the heart, and such despair is more likely to breed and spread in places where humans gather.

And these ghosts feed on such despair, and the more you fear them, the stronger they become.

However, these ghosts are certainly not invincible, and many of the human beings have reacted, and the walls of the city have flashed with dazzling light.

"Purification!"

"Holy Light Technique!"

These are not high-level magics, but they have a miraculous effect on ghosts, as long as they are shrouded in these spells, they suddenly feel a sense of warmth.

Moreover, even an ordinary soldier's sword can cause damage to ghosts, and for a collection of negative emotions like ghosts, the blood on the soldier's knife is also quite lethal.

Although the momentum is very strong, these ghost armies in the black fog are actually not that strong, and of course they also have their own advantages.

After the garrison on the city wall reacted, the figures of these ghosts gradually disappeared, and they were able to hide themselves in the black fog, even if the black fog was constantly dispelled, it would not hurt them.

And the most lethal thing is that there are no obstacles in front of these ghosts, their bodies can easily pass through any obstacles, and from time to time they appear behind some soldiers to inflict mental attacks on them.

They don't even need a powerful spiritual attack, at least a little bit of impact on their emotions is enough, they will die at any time on the battlefield, and that kind of desperate emotion is just suppressed in the depths of their hearts, as long as they are guided a little, they can be fermented.

It was a visceral fear, like a basin of ice water poured from head to end, enough to make people cold and inintuitive.

Even if many magicians are desperately trying to purify these ghosts, after all, they can't strengthen the entire city wall, and the impact of the ghosts on the back of the army is undoubtedly huge, and many soldiers have dull eyes from time to time, and the movements of their hands are much slower.

As long as it harasses, the purpose of these ghosts is this, this is the first time that a special life form like a ghost has appeared on the battlefield, and the effect seems to be better than imagined.

But of course, the victory or defeat on the battlefield cannot be relied on them, they are only adding chips to this war.
