In mid-air, the black and white archmage's face was a little gloomy, although he had heard of the Holy Spirit of the Castle of Black Sand Castle, he had not really seen it, and now, when he really saw the Holy Spirit of the Castle, he felt a great threat.

"Black and white archmage, you Osmu's good calculations want to weaken the strength of my southern spellcaster's world?

The Archmage of Black Sand Castle sneered, and then he whispered to the Holy Spirit of the Castle, and this huge Holy Spirit of the Fortress seemed to be able to understand the words of the Archmage of Utop, and its huge body really moved.

"Phew".

The Holy Spirit of the Fortress stretched out a "leg" and kicked directly at the black and white archmage in mid-air, that leg was like an incomparably thick pillar, and the whistling wind was terrifying, even the black and white archmage was slightly startled.

"Bang".

The attack of the Holy Spirit of the Castle directly hit the defensive spell arranged by the black and white archmage, and this defensive spell was also quite strong, and it was released by the black and white archmage himself, but in the face of the attack of the Holy Spirit of the Fortress, it only lasted for a moment, and then it burst open.

The black and white archmage was shocked, and hurriedly summoned the black-robed archmage to him, the black-robed archmage is his alchemy clone, and he is also very powerful, often whenever there is danger, the black and white archmage will block the alchemy clone in front of him.

"Snort".

The "thick legs" of the Holy Spirit of the Castle appeared densely packed with spikes, easily piercing the body of the black-robed alchemy clone, which used to be able to withstand almost any amount of strength, but now it looks so fragile.

The Black and White Archmage was shocked. He far underestimated the strength of the Black Sand Castle. Even Osme somewhat underestimated the strength of the Black Sand Castle. I didn't expect the Holy Spirit of the Castle to be so terrifying, not to mention that only one archmage came this time, even if Osim sent two more archmages, he might not be able to get the Black Sand Castle.

Every large-scale spellcaster organization has its most powerful hole cards, which are inherited for thousands of years, and are far from being comparable to ordinary forces.

The Holy Spirit of the Castle is the hole card of the Black Sand Castle, as long as there is the Holy Spirit of the Castle. Black Sand Castle is safe!

"Zizizi".

At the same time, the two sharp horns on the head of the Holy Spirit of the Castle actually began to flash with electric light, and the trace of electric light contained terrifying power, and even the sky suddenly became dark.

"Let's go, we can't stay any longer, all the spellcasters of Osmu, withdraw!"

The black-and-white archmage roared, and then he grabbed the black-robed alchemy clone with one hand, and quickly retreated towards the black sand castle.

The black-robed alchemy clone has now been hit hard. It has no combat power, but it is only an alchemy clone after all. Therefore, as long as you go back and repair it carefully, there is a possibility of recovery, and an alchemy clone comparable to an archmage, the black and white archmage will naturally not give it up.

At the same time, the voice of the black and white archmage also spread throughout the Black Sand Castle, and for a while, many strange spellcasters quickly flew out from everywhere, all of them were Osmus's spellcasters.

Some are fourth, fifth, and sixth level spellcasters, of course, some are terrifying, they are above the seventh level, as soon as they make a move, they all carry the power of terror, Osme is raging in the black sand castle, so far, there are some injured, but no more than three are dead.

With such amazing strength, it is no wonder that Osmu can fight against almost all spellcaster organizations without falling behind, one is because their lair is difficult to find, or cannot be found at all, so they cannot deal a devastating blow to it.

And another reason is that because Osmu's strength is too strong, every member is a genius, almost invincible under the same level, and can even challenge beyond the level.

When such a group of geniuses gathered in Osim, almost every part of the spellcaster could subvert a powerful spellcaster organization.

However, this time they picked the wrong target, the Holy Spirit of the Black Sand Castle was so strong that even the alchemy clone of the Black and White Archmage was severely damaged, and they fled in a hurry, not to mention the other members of Osme.

"Woohoo Woooo

Finally, the two sharp horns on the head of the Fortress Protector Spirit had accumulated enough thunder and lightning power, and so, with a strange roar of the Fortress Guardian Spirit, thunderbolts fell from the sky one after another, locking every spellcaster in Osmu.

"Bang bang bang".

Osmu's spellcasters, below level seven, are almost impossible to resist, as long as they are locked by the Holy Spirit of the Fortress, it is difficult to resist, therefore, Osmu's spellcasters are all screaming and dying before they can escape from the Black Sand Castle.

"Ha Luha, it's fun, it's really good! Osm, since you're here, you have to leave something behind!"

Archmage Uto laughed, because this time Osim suddenly attacked, the Black Sand Castle was completely unprepared, it can be said that it was a heavy loss, if the loss alone was nothing, and this time, Osme rushed into the Black Sand Castle as if he was in a no-man's land, which was a huge prestige blow to the Black Sand Castle.

After all, Black Sand Castle is a large spellcaster organization, and it was proposed to deal with Osim, but now it has been attacked by Osim's spellcasters, which can be regarded as a ruined reputation, and for a long time to come, Black Sand Castle will be ridiculed by other large spellcaster organizations because of this incident.

Thinking of this, Uto and Archmage Tumen were a little angry, so no matter how big the price was, activating the Holy Spirit of the Fortress would make Osmu pay a heavy price this time.

Merlin was a little dumbfounded and watched the "slaughter" of the Holy Spirit of the Fortress, it was indeed a slaughter, and under the thunder and lightning of the Holy Spirit of the Fortress, there was no strength to resist it at all.

These geniuses of Osim could have had a chance to become seventh, eighth, ninth, and even archmages, and each of these people was a true genius, the pride of heaven in the power they had stayed in before, carrying the hope of the caster organization.

But now, under the "slaughter" of the Holy Spirit of the Fortress, they were killed by lightning one by one.

The power of the Holy Spirit of the Castle is undoubtedly revealed, this is the hole card of the Black Sand Castle, Merlin suddenly thought of the Dark Spirit Domain in his mind, the Dark Spirit Domain used to be a powerful force comparable to the large spellcaster organization, I wonder if there is a powerful hole card in the Dark Spirit Domain?

Maybe there is, maybe not, such hole cards must be in the hands of the core of the Dark Spirit Domain, that is, the only ninth-level mage, and even Master Leo doesn't know.

Merlin's eyes looked around, and there were still a large number of Osmu's spellcasters who successfully withdrew, but most of them were spellcasters above level seven, and as for the spellcasters below level seven, those who did not have time to withdraw were directly bombarded by the Holy Spirit of the Castle.

It's just that among these people, Merlin didn't see Claes's figure, it was obvious that Claes had already withdrawn from the Black Sand Castle early and escaped a catastrophe, facing the Holy Spirit of the Castle, not to mention that his spatial blade only cultivated to the third form, even if he cultivated to the fourth form or even the fifth form, he would never protect the opponent of the Holy Spirit of the Castle.

The entire Black Sand Castle looked very chaotic, although there were some ninth-level spellcasters of the Black Sand Castle who came out again to maintain order, but after such a fuss as Osim, so many mages in the caster organization died, so no matter how much the casters of the Black Sand Castle promised, they could not reassure these mages.

"Mage Leo, what do we do now? stay in Blacksand Castle or return to the Dark Realm?"

Merlin hesitated for a moment, but asked in a low voice.

Mage Leo groaned, and said after a while: "Leave the Black Sand Castle first, I'm afraid the chaos here will last for a while, Osmu's sudden attack has also been prepared for a long time, this time, the Black Sand Castle itself is in chaos, and the entire Southern Spellcaster World will continue to be chaotic, if the situation is not controlled, I'm afraid Osmu's purpose will be successful, and the Southern Spellcaster World will not be able to unite to deal with Osme at all." However, these have little to do with us, if the three large spell caster organizations can unite and control the situation, then they will naturally notify us, if we can't control the situation, we can just return to the Dark Spirit Domain, and we won't participate!"

Master Leo's approach is very safe, and for now, he still has to rush back to the Dark Spirit Domain first, after all, the Dark Spirit Domain has lost three seventh-level mages, which can be regarded as a heavy loss, and he can't continue to participate in this matter.

"Okay, since you are leaving, then our Black Sand Castle will not stop it, and completely open the rune array!"

Finally, the casters of the Black Sand Castle decided to let go of the rune circle completely, and many of them must have the same desire as Master Leo, and they all wanted to leave the Black Sand Castle as soon as possible, and did not want to continue to stay here to participate in this matter.

Osmum has left, and the loophole in the rune circle of the Black Sand Castle has also been repaired, if you want to leave, you have to open the rune circle, there are so many casters who ask to leave, and the Black Sand Castle cannot be forcibly kept, only the rune circle can be opened.

It's just that, after this chaos, the prestige of the Black Sand Castle will be reduced to the lowest point, and even in the Black Sand Castle there is no guarantee of safety, who will dare to go to the Black Sand Castle with confidence in the future?

As a large caster organization, the invisible loss of reputation is even more significant than the loss of casters in the Black Sand Castle.

Archmage Uto and Archmage Tumen also looked at the casters below one by one leaving the Black Sand Castle with cold eyes, and the Utopian mage had the intention to continue to pursue Osmu's people, but the Holy Spirit of the Fortress currently had little power left, and needed to continue to sleep.

And the Black Sand Castle is not clear, whether Osme only sent these people, if there are still Osmu's spellcasters entering the Black Sand Castle, I am afraid that the Black Sand Castle will be dangerous, so Utopian Mage and Tumen Mage still decided to sit in the Black Sand Castle, just in case.

Seeing that many spellcasters were leaving, Mage Leo also said in a deep voice, "Okay, let's go too!"

So, Mage Leo took Merlin and the rest of the Dark Spirit Realm and left the Black Sand Castle as well. (To be continued......)
