"Your method has failed again." The powerful skeleton, whose details were completely unknown, spoke coldly again.

This time, he accompanied the Fallen to fight disguised as the vanguard cannon fodder army, and the tens of thousands of skeleton mages who helped him in the battle were all subordinates of this skeleton, so he was the only one who could control these skeleton mages. It was only before he stepped forward and gave all the skeleton mages an order to fight in formation: summon skeleton soldiers to take a path at all costs, and cast all their magic power to gather acid rain to siege the city.

Although skeleton mages are mages, they can form a mage group after forming a scale, but after all, they are only third-order undead, not only can they cast only a few kinds of undead spells, but even their own magic power is really limited.

Summoning a skeleton soldier, although the mana consumed is not very large, a skeleton mage can easily summon four or five times. But what good is it to build a staircase of bones that can pass through the walls of the fortress that is thirty meters high? Therefore, at the very least, there must be 20,000 skeleton mages to focus on this, not to waste, but to build the bone ladder successfully.

This is the core goal of this vanguard force.

But the defenders on the fortress will definitely not let the army of the undead build, through the previous offensive and defensive battles, whether it is Aderozo or this powerful skeleton, it has been seen that the final construction of the white bone ladder will definitely be successful, but the time they need to consume is definitely not short, and the loss will be great. This was not what they wanted to see, not to mention that they didn't know what the Void Duchy's plans were going to do in the future, so in order to avoid long nights and dreams, they naturally had to shorten the time as much as possible.

Therefore. When he went into battle, Aderozo prepared two tactics.

The first is to constantly summon skeleton soldiers. Putting enormous pressure on the enemy, hitting their morale and confidence. Force the other side out of the city to fight.

It's a pity that this tactic was recognized by William, so Alfred's request for war was naturally not approved, but William calmed the army's heart with a few words.

If the first tactic fails, then naturally the second tactic can only be used.

The skeleton beside Aderozo ordered the skeleton mage legion to go all out, desperately summoning all the skeleton soldiers, and then quickly building a bone ladder, while allowing the other part of the skeleton mages who had mastered the spell of acid rain to form a large magic array, forming a magic chain to share the magic power with each other. Unleash a strong acid rain that envelops the entire fortress. The purpose is also very simple, that is, the opponent can only watch the construction of the bone ladder but is powerless to stop it, and the cast range of the strong acid rain cloud is only limited to the fortress, and will not affect the outside of the fortress.

Although the tactics were different, the goal was the same: to force the defenders out of the city.

Unfortunately, it turned out to be a failure.

William still had no intention of letting the legion out of the city to fight.

"Even if you can't force them out of the city, it can still hit their morale, and even cause a certain degree of damage and weakening to the defenders in the fortress." Aderozo's mood was cold, and he said in a deep voice. "Besides, when your strong acid rain magic is over, the Bone Staircase will be completed, and I will have already fought the enemy on the city wall by then. …… At all costs. We are all on the winning side. ”

"It was better to do so." The skeleton replied coldly, "The words of the torrential rain are too late to suppress it, and what I ordered is the slow rain." After about twenty minutes, the Bone Staircase was completed. You can start preparing. ”

As the skeleton said, the clouds in the sky were not rainstorming. Moreover, the rain curtain is not large, but it is very continuous and continuous, which is very in line with the rainy season situation in the southern continent. However, this kind of continuous drizzle has always been the most hated by the people of the southern continent, because this kind of weather will cause the air humidity to increase, and there will be a lot of rainy days in a row, it is difficult to dry the clothes, and there is a musty smell.

At this moment, the steel wings and others in the fortress were very angry.

Although the rain was not heavy, and the damage to the shock shield was not too obvious and severe, it would undoubtedly delay this almost tormented time, and the demoralization and damage would be more severe than the next rainstorm.

However, the army of the Void Principality is a strange freak, such as Iron Wings, Thunder Lion, Cecilia Guard, etc., it is very difficult to make them reduce their morale, and even the Cecilia Guard under the command of Clover will not be defeated at all even if there are only a few hundred people left in the end of a war.

This kind of elite army exists almost exclusively in those empires and super-first-class kingdoms, but the Void Duchy has it.

But no matter what, the appearance of the mage regiment is indeed a very terrifying strategic weapon. As long as they appear on the battlefield, they can often directly turn the tide of a war, but not everyone can afford to raise a mage group - the so-called mage group must have at least hundreds of official mages, and then connect the power of all mages together through a special magic chain to be able to cast powerful battlefield-level or even strategic-level magic.

Therefore, the battlefield where the mage regiment generally appears must be a national war at the level of a first-class kingdom.

At that time, the battlefield between the Duchy of Lane and the Kingdom of Dabion, no one of the three major battlefields had the intervention and participation of the mage group, although there were magicians joining the war on the local battlefield, but it could not form a scale that directly turned the situation on the battlefield.

The foundation of the Void Principality is still insufficient after all, even if it has the level of a super-first-class kingdom or even an empire in all aspects, but the mage group still does not have it. Even though Sean came up with the idea of having the Priest Combat Group replace it, the Priest Combat Regiment could only carry out some divine auxiliary blessings to make the war legion stronger, and in the face of the powerful war magic attack formed by the real mage group, it could not produce enough anti-magic damage.

The construction of the White Bone Staircase was getting faster and faster, and in the blink of an eye, it had climbed from a height of seventeen meters to twenty-four meters, and another six meters would be able to match the height of the walls of the entire Savage Fortress.

"It's a pity." Watching the white bone staircase gradually form, Aderozo's heart sighed softly.

The cavalry charge is at its most powerful when it is in the height advantage. That is, when charging from uphill to downhill; The second is a frontal charge with a sufficient distance, such as an area such as a plain at a distance of 100 meters. But the structure of the white bone ladder. But it was a backlash from the bottom up, which required twice as much loss on the cavalry charge as usual. Even the charge will be inferior.

It's just that Aderozo doesn't have a choice.

He had already seen that the defender standing on the city wall was very strong, and if it weren't for the fact that he had transformed and forcibly increased the strength deployed under his command through demonic means, he was afraid that if he encountered such an army at other times, it would only be him who would be defeated. Therefore, he could only let his cavalry troops take the lead in the charge, and only in this way could he have more hope of opening a hole, and then tearing a wound, so that the follow-up troops could continue to attack the city wall. And stand firm.

This is war.

If he could manage it slowly, he certainly hoped that the Bone Staircase would be able to build a platform with a length of 100 meters, which would be more suitable for his legion.

But alas, he doesn't have such a platform.

The lack of material was one factor, and the other was that he didn't think that the "companion" around him would help him like this.

A skeleton cavalryman led a horse out of the cavalry formation.

It was a skeleton with only a skeleton remaining, but as was the case with the entire Legion, it was also an illusion shield. In fact, it was a war horse with black flames burning on all four hooves. The horse's body is as black as ink, and its eyes have a bright red light, which looks particularly fierce and hideous, and the horse is not wearing a vest. It's not that it's unprepared, it's that it's not needed.

This is not a horse from the plane of bones, but a horse-like monster unique to the native world, the Firehoof.

This monster has a lot of impact power and speed. It only grows near the thousand-year Covenant Empire in the Southern Continent, and is the favorite mount of many knights. It is also an important economic source of export and sales of the Millennium Covenant Empire. Originally, Aderozo's firehoof beast was only a sixth-order, but after Aderozo's strength as a Fallen was improved. His mount has also been strengthened in the same way, and now it already has the strength of the eighth order, plus some special things given by the undead clan, it is not an exaggeration to say that it is a ninth-order demonic beast.

Aderozo rolled over his horse, then wielded a spear in his right hand and stared at the walls of the fortress with a nonchalant expression.

At this time, the height of the white bone staircase had been built to twenty-nine meters, and countless skeleton soldiers were frantically climbing up, preparing to turn into the last meter of the staircase.

With a wave of Aderozo's hand, the entire undead cavalry phalanx suddenly split into two rows: one on the left and one on the right.

At this moment, a fiery red tornado suddenly broke through the city walls.

Bright red, blazing, and furious, this is how this huge fiery red tornado, which has a diameter of five meters, feels to everyone present.

When the tornado rose up, pierced the dark clouds in the sky, and began to spread rapidly, dyeing the sky into the color of a burning cloud, the acid rain falling from the dark clouds began to gradually decrease. And in those areas that were affected by the flaming tornado and turned into fiery clouds, the acid rain stopped falling directly, leaving only a layer of bright color.

In an instant, among the group of skeleton mages who performed acid rain magic, one white mist after another exploded.

These are all skeletons that were directly killed by the impact of the flame tornado, which caused the acid rain to react with magical power.

However, these dead skeleton mages only accounted for a very small part of the entire huge skeleton mage group, not even a thousand. Although the explosion continued, it was Cecilia who was taking advantage of the danger - the skeleton mage's magic consumption was close to the end of the crossbow, and even if Cecilia did not cast this tornado, the acid rain would soon be over. It's just that she is unwilling in her heart, unwilling to be pressed and beaten like this and can't create some losses to the undead army, so she chooses to make a move at this moment.

"Hmph." The skeleton with a mysterious identity didn't seem to care at all about the continuous sacrifice of the skeleton mage under his command, and still only let out a sneer, "Struggle, despair, unwilling...... The more you are like this, the more delicious your soul will be! ”

As the skeleton's words fell, the last meter of the white bone staircase was finally built, and the soul fire in its eyes suddenly lit up a few more times.

All the skeleton mages who were casting spells immediately stopped, and quickly retreated to the left and right, making way for the middle path leading to the bone staircase. And those skeleton soldiers who have not had time to turn into the material of the white bone ladder will simply rush to the city wall and quickly climb the city wall, they will be the best bait to create chaos. This is also the usual practice that the undead army will use after creating the Bone Staircase: use the skeleton soldiers who have not yet been used up to create chaos on the city wall, provide better fighting space and occasions for the subsequent undead army, and occasionally even take the city wall before the subsequent army can climb the wall.

However, in the face of the elite army of the Void Duchy of Iron Wings, it is obviously impossible to do so.

Aderozo let out a roar, and the skeleton cavalry troops of the left and right phalanxes slowly began to run forward. (To be continued.) )
