Merlin saw Wizard Leo walking out of his house the moment he arrived at his courtyard.

"Teacher Leo, what happened?"

Merlin hurried up and asked in a low voice.

Wizard Leo took a deep breath and extended his frail fingers. Mysterious runes flew out from the Dark Magic Ring on his finger immediately. A deep-toned and slightly anxious voice rang out from these mysterious runes, "Leo, hurry back to the Dark Magic Region. Something big has happened!"

Merlin could feel his heart move. This voice sounded very familiar. He thought about it for a moment, and asked hesitantly, "Is that Wizard Heusius?"

Merlin was not familiar with the Seventh-level Spell Casters of the Dark Magic Region. The only one he was familiar with was Wizard Heusius. He also knew that Wizard Leo had a very tight-knit relationship with Wizard Heusius.

"Yes, it's Heusius. He knew that I came to the Imperial City because I briefly mentioned it to him before I left. I don't exactly know what's going on, but Heusius is a very cautious man. He wouldn't send such messages for no reason. I'm afraid that something big has really happened. Merlin, we need to go back to the Dark Magic Region as soon as possible!"

Wizard Leo had already decided to rush back to the Dark Magic Region. Now, he was only informing Merlin as he had prepared to bring Merlin back with him.

Merlin also nodded. "Alright then, let's go and explain the situation to the eighth prince."

Shortly after, Merlin and Wizard Leo went to bid farewell to the eighth prince.

…

"It's a pity, Wizard Leo, Wizard Merlin. Since there's something in the Dark Magic Region that requires you to go back, I'll naturally not stop you. Nonetheless, I just want to let you two know that we welcome you back at any time!"

After listening to what Merlin and Wizard Leo had said, a slight disappointment showed on the eighth prince's face. Wizard Leo was the strongest Spellcaster that he had guarding him. With Wizard Leo here by his side, the eighth prince could handle things more smoothly and effectively in the Imperial City.

"Let's go then."

Wizard Leo did not add anything either. He brought Merlin with him and left the eighth prince's manor right away.

Merlin ordered Wizard Bammou who was behind him, "Bammou, go back to Wilson Castle and protect the Wilson clan. Everything else can wait until I've returned."

Deep down, Bammou felt slightly relieved as he could finally return to Wilson Castle and restore his Magic Power with a peace of mind. He did not really enjoy staying by Merlin's side because he found himself busy every single day as though there were endless things for him to do. There was almost no time for him to recover his Magic Power.

"Whoosh whoosh."

After everything was arranged, Merlin and Wizard Leo leaped into the air and quickly flew toward the Dark Magic Region.

…

"Swoosh."

A white light flashed by, frightening a few seabirds which were playing on the beach.

Two figures emerged from the white light. They were Merlin and Wizard Leo, who were rushing a long journey back from the Imperial City to the Dark Magic Region.

Wizard Leo did not stop for long and continued to walk inside. Meanwhile, Merlin looked at the stone tablet of the Dark Magic Region, only to find that the black cat Didimoss seemed to have not appeared for a long time.

"Teacher Leo, why hasn't the spirit of the Runic Magic Circle of the Dark Magic Region Sir Didimoss appear recently?"

Merlin could not help but pointed at the stone tablet as he asked Wizard Leo.

Wizard Leo stared deeply at the stone tablet, and said meaningfully, "Sir Didimoss has gone into in a deep slumber. As the spirit of the Runic Magic Circle, he could manipulate all Runic Magic Circles of the entire Dark Magic Region. The only Ninth-level Spell Caster that was controlling the Runic Magic Circle needed Sir Didimoss' cooperation. Hence, it should be a long time before he would wake up again... Alright, let's go. Let's find out what has happened to the Dark Magic Region."

After he had finished speaking, Wizard Leo took the lead and entered the Dark Magic Region. Merlin once again glanced at the stone tablet that the black cat Didimoss resided. As the spirit of the Runic Magic Circle, it was necessary for him to cooperate with the powerful Spell Casters of the Dark Magic Region to control the entire Runic Magic Circle.

This may also involve some secrets of the Dark Magic Region, so Wizard Leo would not say too much.

Merlin did not stop there for long either as he followed Wizard Leo into the Dark Magic Region.

Upon just entering the Dark Magic Region, Merlin saw the familiar tall towers once again. At the thought that he might become a Fourth-level Spell Caster in the near future and could build a tower all by himself, Merlin's mood seemed to become a little excited.

Everything was calm in the Dark Magic Region. It did not look like something big had happened. Still, they could only truly be sure what had happened until they met Wizard Heusius in person.

"Teacher Leo, I shall go back to the tower first."

Merlin bid farewell to Wizard Leo. After all, it was Master Heusius who was looking for Leo. There must be something very important, so Merlin had no reason to follow.

However, Wizard Leo frowned instead and shook his head gently. "You don't have to go. The message that I got from Heusius meant that I have to bring you along."

"Bring me along?"

Merlin was a little surprised. How could this matter be related to him?

Wizard Leo did not say anything. He brought Merlin with him and flew to the few tallest tower in the Dark Magic Region.

It was not Merlin's first visit to Wizard Heusius' tower. Thus, he only threw a few casual looks at it and then looked toward the front.

Just when Merlin and Wizard Leo had just arrived at the tower, a black-robed Spell Caster came up to them – it was Wizard Heusius.

As a Seventh-level Spell Caster, Wizard Heusius had a very lofty status. In addition, he had a relaxed look, but this time, his expression was extremely solemn, and his eyes had revealed his worries.

"Heusius, tell me what happened. Why have you called me back so urgently?"

The blood-shot vertical eyes in Wizard Leo's forehead glimpsed slightly. Adding that with Wizard Leo's slim as a "dry carcass" body, it looked even more terrifying.

Heusius did not answer immediately, but instead, he asked in a slightly grim tone, "Leo, what's wrong with you?"

Wizard Leo's current image had changed too much. It was because he had forcibly employed the fourth form of Darkness Eye when dealing with Wizard Tanin and Wizard Morston. As a result, he had been devoured by Darkness Eye as a form of a backlash, thus this horrendous appearance.

"Nothing really, it's just a little problem with Darkness Eye, it's not a first."

Wizard Leo responded casually, seemingly not worried at all.

Seeing that Leo had mentioned Darkness Eye, Wizard Heusius did not continue to ask. After all, Darkness Eye was very magical. Back then, no one had thought that Leo would be able to kill Wizard Osseus from Ozmu. Therefore, perhaps there was indeed something peculiar with Darkness Eye which could explain why it had made Wizard Leo become like this.

Moreover, apart from the drastic change in his appearance, which now looked really horrifying, the life force on Leo's body had not changed much.

Heusius took a glance at Merlin and then said deeply, "A huge incident has indeed happened, but it's an incident which involved all spell casters' organizations! Recently, our Dark Magic Region got a notice from Blacksand Fort, a large spell casters' organization. They called for us to go to the Blacksand Fort summit in a month's time."

"Isn't the Blacksand Fort summit held every once in ten years? It has only been eight years since the last one. Even if there was to be one, wouldn't that be in another two years?"

Wizard Leo looked at Wizard Heusius suspiciously. There must certainly be another hidden reason why Blacksand Fort would hold the summit in advance.

Heusius pondered for a moment, then slowly said, "There's naturally a reason why Blacksand Fort is holding the summit in advance. In fact, the summit was only an excuse. This time, they wanted to gather various spell casters' organizations using the name of the summit. It's to discuss a huge matter together."

"What huge matter?"

Even Merlin was holding his breath and listening carefully to Wizard Heusius' answer.

Wizard Heusius took a deep breath and spit out the word from his mouth, "Ozmu!"

"Ozmu? You mean, Blacksand Fort is now ready to deal with Ozmu?"

The blood-shot eyes in Wizard Leo's forehead opened fiercely, exuding bursts of blood-light illumination. It revealed the unrest in Wizard Leo's mind.

Ozmu was a mysterious organization. Almost no one knew where its old nest was. No one knew how many members Ozmu had, or how strong they really were.

The only thing everyone knew was that Ozmu would launch a large-scale assault every once in a while. Be it blackmail or recruit, in short, Ozmu would try whatever they could to bring all the genius Wizards of some spell casters' organizations or Spell Caster clans into Ozmu.

Besides, Ozmu also had an outrageous rule which applied to all Spell Casters who were recruited – once their strengths had attained maximum capacity in the future, they had to return to their previous spell casters' organization or clan which they had betrayed to wipe them out.

Therefore, every spell casters' organization or Spell Caster clan bore a shared hatred toward Ozmu. Yet, for so many years, Ozmu had still existed, and they were getting stronger and stronger. Nobody could inflict any sort of major loss on Ozmu.

Previously, Wizard Leo had hunted Osseus down for thousands of miles, and also succeeded in killing him. This incident had become quite a sensational event in many spell casters' organizations, making Wizard Leo famous and elevating his great name.

The real reason was that Osseus was a Seventh-level Spell Caster in Ozmu. Therefore, this incident could bring such a great impact and cause such a big shock.

Now that Blacksand Fort was planning to deal with Ozmu through organizing a summit, it made Wizard Leo naturally very surprised.

Wizard Heusius gently shook his head instead. "It's not that Blacksand Fort is now ready to deal with Ozmu. It's actually those top-notch large spell casters' organizations that want to deal with Ozmu! Heh heh, the impact of Ozmu on small and medium-sized spell casters' organizations like us wasn't really that great. However, for large spell casters' organizations, Ozmu has caused much damage to them. After all, there were numerous genius Spell Casters in the large spell casters' organizations. Hence, Ozmu has also planted their focus on those large spell casters' organizations.

"This time, Blacksand Fort had discussed with other top-notch large spell casters' organizations in the dark. They need to unite most of the spell casters' organizations and deal with Ozmu together, so its scale is the largest ever. In addition, these large spell casters' organizations have already made up their minds. Even if they can't destroy Ozmu this time, they must also make Ozmu suffer a huge loss, so that they won't be able to stir any more trouble in a short time."

The things that Wizard Hersius had said should only be known to only the higher-ups of the spell casters' organization as it could be deemed highly-confidential.

To deal with Ozmu, in which many large-scale spell casters' organizations had discussed in private and had made up their minds, this was indeed a major issue affecting the entire Spell Caster world.
