Wizard Leo remained silent for a moment. Then, he raised his head and said, "Ozmu is far more mysterious than us Dark Magic Region. Who knows where their headquarters is? If we can't find their base, how can we incur damage or even destroy Ozmu?"

Ozmu had the ability to exist for so long, and even large spell casters' organizations could not do anything to it. So naturally, it must have its unique traits. If it was so easy to be destroyed, then Ozmu might have already been long gone.

Wizard Heusius continued. "Of course. If we want to inflict a heavy hit upon Ozmu, we have to find its old nest! On this point, Blacksand Fort had secretly revealed a info that they've secured the location of the old nest. As long as there's a decision to act upon, the Great Wizards will lead the command and we'll directly infiltrate it!"

"The old nest of Ozmu has been located? How is that possible?"

Wizard Leo was still somewhat in disbelief. Although Ozmu had had a long history, no one had been able to find its old nest.

"Whether it's true or not, as long as we attend the Blacksand Fort summit in a month's time, everything will become clear."

Wizard Heusius locked gaze with Wizard Leo. There seemed to be another hidden meaning behind that look.

"You want me to go?"

Wizard Leo suddenly understood what Heusius meant.

"Not only do I want you to go. The other two Seventh-level Spell Casters and I will go too. However, I only require you and Merlin to attend the summit. This time, in order to attract a large number of Spell Casters, and in an attempt to unite the numerous forces, Blacksand Fort had even broken the convention by inviting some Spell Caster clans. They even shelled out very precious things to be the prizes for the winners of the summit.

"Wizard Leo, you should be aware that we, the Dark Magic Region, Abyss Fort, Fire City, and Ashes Region are sidelined. In so many spell casters' organizations, we were really just nothing, but on the surface, we're equal. Hence, we'll naturally compete with each other. The original purpose of the summit is for all the spell casters' organizations to flaunt their potential by sending the best Spell Casters in their respective organizations. The Spell Casters will be categorized as the best below the Seventh-level and the best below the Fourth-level, respectively.

"For the Spell Caster below the Seventh-level, we have you, Leo. As for the Spell Caster below the Fourth-level, we have Merlin, the Six-Elemental Spell Caster. I believe that in the summit this time, even if you can't shine, you would surely put up an excellent performance, and at least triumph over Abyss Fort, Fire City, and Ashes Region!"

The meaning of Heusius words were already very clear. The relationship between the Dark Magic Region and Abyss Fort, Fire City, and Ashes Region was not really close. They had always been secretly competing, and would only unite in face of a common threat such as the previous time when they were threatened by Ozmu.

Therefore, in the Blacksand Fort summit this time, the Dark Magic Region wanted to suppress the other three spell casters' organizations, and perhaps the other three spell casters' organizations also had the same idea.

The original intention was to head there and discuss how to deal with Ozmu, but instead, Ozmu had now become a trivial matter. Those large-scale spell casters' organizations may consider the ideas of some medium-sized spell casters' organizations, but they would not pay much attention to small-scale spell casters' organizations.

Many small spell casters' organizations had only one Ninth-level Spell Caster, and some did not have any at all. Such a force was really not worth mentioning for those large spell casters' organizations who had dozens or even hundreds of Ninth-level Spell Casters.

Inviting small spell casters' organizations to the summit was only a simple gesture.

"Since you've come to a decision, I'll head to Blacksand Fort in a month time!"

After all, Wizard Leo was a member of the Dark Magic Region, so he must also obey the decision made by the Dark Magic Region. However, as Wizard Leo had demonstrated immense strength even though he was not yet a Seventh-level Spell Caster, his strength was already comparable to that of a Seventh-level Spell Caster. Therefore, the Dark Magic Region also treated Wizard Leo as a Seventh-level Spell Caster.

They would automatically ask for his opinion with regard to all things related to Wizard Leo.

Seeing that Wizard Leo had agreed to go, Heusius was clearly relieved too.

Thereafter, Wizard Leo and Merlin left Wizard Heusius' tower.

Wizard Heusius' tower was one of the tallest towers in the Dark Magic Region. As a Seventh-level Spell Caster, his tower was naturally built differently from all the other Spell Casters.

Nonetheless, after leaving Heusius' tower, Merlin was surprised to find that there was another peculiar tower which was shrouded in mysterious runes. It was not lower than Heusius' tower.

Yet, the Spell Casters entering and exiting this tower were low-level Spell Casters, which made Merlin somewhat puzzled. In the several years that he had been in the Dark Magic Region, Merlin still did not fully understand everything in the Dark Magic Region.

"Teacher Leo, this tower is built by which Wizard?"

Merlin asked Wizard Leo who was beside him.

"You don't know this tower?"

Wizard Leo cast a suspicious look at Merlin. After seeing Merlin shaking his head, only then did Wizard Leo pat gently on his own forehead. "Actually, it's my fault for never mentioning it. Although you've been in the Dark Magic Region for some time, your actual time spent in the Dark Magic Region hasn't been very long. So, it's normal for you to not know this tower.

"This tower was built by the founder of the Dark Magic Region, the almighty Great Wizard Fidel. It's called the Runic Tower! This Runic Tower had a total of seven floors, each containing a mystical spirit of runes. As long as one could pass the floors one by one, and then finally defeat the spirit of runes on the seventh floor, one could obtain the treasures left by Great Wizard Fidel. As for what the treasure is, no one knows because the Runic Tower only allows Spell Casters below the Fourth-level to attempt it. Therefore, after thousands of years since the inception of the Dark Magic Region, there were at most Spell Casters who had entered the fifth floor. Nobody had been able to step into the sixth floor, let alone the seventh floor."

After a pause, Wizard Leo could not help but smile. "You almost missed the opportunity to attempt the tower. However, it's now still a very suitable time for you attempt it. You're not a Fourth-level Spell Caster yet, so with your strength, you should be able to reach the fifth or even the sixth floor! Throughout the thousands of years history of the Dark Magic Region, no one had ever succeeded to the sixth floor. Even the legendary Kleis could only reach the fifth floor back then."

Merlin looked at the Runic Tower once again and said, "Since it was built by Great Wizard Fidel himself, it was obviously prepared for Spell Casters below the Fourth-level. It wouldn't hurt to try. Teacher Leo, I shall go and try it out then."

Wizard Leo seemed to be interested too as he nodded. "Back at the time when Kleis reached the fifth floor, I didn't get to witness it myself. This time, I can't be missing it one way or another. I'll go with you."

Then, the two turned their directions and flew toward the Runic Tower.

...

Presently, there were only sparse Spell Casters in front of the Runic Tower.

The Spell Casters who could come to the Runic Tower were basically Spell Casters below the Fourth-level. Their purpose would naturally be to try their luck and attempt the Runic Tower.

In this Runic Tower, there were some precious treasures on each floor, which were originally placed by Great Wizard Fidel. As long as one passed the floor, one could get some treasures.

However, after a millennium, many Spell Casters had already passed through the first five floors. Thus, the treasures of the first five floors had all been swept away cleanly.

Only on the sixth and seventh floors would there still be treasures left by Great Wizard Fidel, but for so many years, no one could pass the sixth floor.

"Wizard Sarah, are you ready? Among the three of us, only your study of runology isn't too comprehensive. We both have already mastered every detail of the Runic Magic Circle, and we won't go wrong. "

Among the crowd were three Spell Casters – two males, and one female. They seemed to be somewhat like mavericks as there was no other Spell Casters around them. The remaining Spell Casters each tossed them respectful looks. It seemed that the identity of these Wizards was not that simple.

The man who spoke earlier was a male Spell Caster with short blond hair, and he said that to another female Spell Caster.

The female Spell Caster, who was known as Wizard Sarah, frowned. She replied in a rather dissatisfied manner, "Don't worry Ilman, I've already understood how the Kleinman Runic Magic Circle works. As long as Envia has indeed gotten the Runic Magic Disc, then this time we have real hopes of passing the fifth floor or even the sixth floor!"

The remaining tall male Spell Caster, who was called Envia by Wizard Sarah said in a deep tone, "I've paid a huge price to obtain this Runic Magic Disc, so there won't be anything wrong with it! It only needs three Spell Casters who are proficient in runes to operate it. Let's go and see how many floors we can pass this time?"

It was not their first attempt at the Runic Tower. Each of them could pass the fourth floor all by themselves. It was just that the fifth floor was way too difficult and they could not get past it. Hence, they spent a big price to get this Runic Magic Disc.

The Spell Casters who challenged the Runic Tower were allowed to use the Runic Magic Disc, but the number of Spell Casters who chose to unite their forces could not exceed three.

Runology had always been a specialty of the Dark Magic Region. Great Wizard Fidel's aim of building this Runic Tower could also be to cultivate some outstanding Spell Casters who would excel at runology.

"Swoosh swoosh."

Just as the three were preparing to enter the Runic Tower, two Spell Casters descended directly from the sky, one of whom had a bloodshot vertical eye in his forehead, which looked extremely menacing and terrifying.

"It's Wizard Leo!"

Such a horrific appearance would only belong to Wizard Leo, the famous Wizard of the Dark Magic Region. Many Spell Casters recognized Wizard Leo at first glance.

Despite Leo's atrocious look and his identity as a Sixth-level Spell Caster, coupled with his killing of the Seven-level Spell Caster from Ozmu, his status in the Dark Magic Region was no less than those Seventh-level Spell Casters. Therefore, although the surrounding Spell Casters had some fear in their hearts, they still bowed toward Wizard Leo one after another.

"That person beside Wizard Leo seems to be Wizard Merlin?"

"It's really Wizard Merlin. He hasn't challenged the Runic Tower yet, right?"

"Indeed. Wizard Merlin has never challenged the Runic Tower. Back then, Kleis had passed the fifth floor, but unfortunately, he didn't pass the sixth floor, so he didn't get the treasure Perhaps, Wizard Merlin could pass the sixth floor!"

Seeing Merlin alongside Wizard Leo, many Spell Casters were able to immediately guess Merlin's purpose here. He had come to challenge the Runic Tower. Merlin was the best Spell Caster in the Dark Magic Region after Kleis – he was even a Six-Elemental Spell Caster!

Thus, the Spell Casters of the Dark Magic Region would inevitably compare Merlin and Kleis. It was just that the two of them had never really battled against each other. Now, it was possible to compare who was better between the two by their attempts at the Runic Tower.

In the distance, Wizard Sarah, Wizard Envia, and Wizard Ilman looked at each other and felt the grimness in each other's eyes.

"Merlin has actually come. Back then, Kleis almost passed the sixth floor. This Merlin was said to be in no way inferior to Kleis, and that his future potential is far brighter than that of Kleis. Maybe he can really beat the sixth floor, and obtain the treasures! We've paid such a huge cost to get the Runic Magic Disc, all so we can get through the sixth floor, and get the treasure. We can never let any other people pass the sixth floor before we do. Come, let's challenge the Runic Tower now!"

Wizard Envia said with a low voice, his expression seemed a little anxious.

The other two Wizards nodded in unison. They did not dare to look down on Merlin. After all, Kleis, the Five-Elemental Spell Caster back then was already scary enough, let alone Merlin, who was a Six-Elemental Spell Caster.

Hence, the three did not stop for any longer and quickly entered the Runic Tower.
