Up in the sky, clusters of clouds were pierced by the three-headed dragon. Even the Spell Casters felt chilly and cast spells to insulate themselves against the cold draft.

Except for Merlin, who did not seem to feel anything at all. He had shut his eyes quietly, but his invisible Mind Power was rummaging through Kleis' beacon ring.

Kleis' ring contained many valuable items. There were millions of elemental crystal stones. Possessing such an immense number of elemental crystal stones in the Glorious Land was absolutely unbelievable.

Other than elemental crystal stones, Merlin also saw voluminous precious alchemy materials, potion materials, and even some runes, all left behind by Kleis. As the crème de la crème among the prodigies, Kleis was also very proficient in runology, potions, and alchemy. Such a prodigy was rare to find even un the Void Zone.

Although there were countless valuable treasures inside the beacon ring, the most precious items were Spatial spells and Spatial Demon Ability. Merlin also found Kleis' notes on Spatial spells which he hurriedly flipped through the moment he got his hands on the ring.

The Spatial spells were contained inside a Spell Manual which was far more detailed than Old Man Eita's Spell Manual. Kleis had documented all the Spell Models he had constructed with meticulous detail, all the way from his Zero-level spell to becoming a Great Wizard. Such a detailed Spell Manual would be highly precious even in the Void Zone.

It was especially so when the contents were about Spatial spells. These were very rare spells. Across the entire Void Zone, the total number of Spell Casters with Spatial gift could be counted with one hand. In fact, the number of those who eventually managed to become Spatial Great Wizards was even more negligible.

At least, Merlin did not encounter any Great Wizard with Spatial spells among the numerous Spell Casters involved in the civilization war.

Merlin flipped through Kleis' notes page by page carefully. Back then, Kleis had obtained a Spatial spell tome together with its Demon Ability under unexpected circumstances.

Then, he followed the test given and discovered that he indeed had Spatial talent. Therefore, Kleis had managed to become a Spatial Wizard quite easily.

It was not a smooth-sailing journey for after becoming a Spatial Wizard though. This was because the Spatial Demon Ability was too dangerous. At one point, Kleis had no idea what to do with it. He did conceive an idea of using a Runic Magic Circle to suppress the hidden dangers after a while.

Afterward, Kleis had infiltrated the Dark Magic Region. That was because the Dark Magic Region was unmatched in the field of runology despite being a small Spell Caster organization. Even those large Spell Caster organizations were not a match for it.

With Kleis' talents, he soon earned the approval of the Dark Magic Region. The Dark Magic Region nurtured Kleis with all their might, and he was able to obtain the Runic Magic Circle he desired.

The Dark Magic Region could no longer support his quest to become an even stronger existence at the end. Kleis had chosen to betray the Dark Magic Region and defect to Ozmu as a result.

The series of events that occurred thereafter was already known to Merlin. It led to the uprising of the southern Spell Caster world against Ozmu. The southern Spell Caster world was defeated, and the Dark Magic Region was then forced to evacuate to Subzero Snowfield. Soon after that, Merlin had entered the Void Zone accidentally while Kleis gradually advanced to become the strongest Spell Caster in Ozmu and eventually became the First Elder!

"Phew…"

Merlin heaved a long sigh. It seemed like Kleis' experience was not at all inferior compared to Merlin's exciting experiences. Kleis not only understood the art of endurance, but he also had talent and determination. For a prodigy such as Kleis, it would not be surprising if he managed to become a Great Legend, Honored Legend or even a Lord in the Void Zone.

"This Spell Manual is very useful. Spatial spells and Spatial Demon Ability are extremely previous!"

Merlin isolated the Spatial Spell Manual and stored it securely. Although he did not have any Spatial talents, one day he might encounter someone who had Spatial talents. When that time came, this Spell Manual would be highly useful to that person.

Boom!

The huge three-headed dragon landed on the ground heavily. Its enormous body caused the entire mountain to tremble.

"Wizard Merlin, we're here!" Wizard Tamo said solemnly, looking at the very ordinary-looking mountain in front of them.

Merlin opened his eyes. The location given by the beacon ring was indeed here. Ozmu Headquarters was hidden nearby.

This forest that appeared to be completely ordinary might pose a stumbling block to others to find anything out of the ordinary inside, but Merlin's Mind Power was incredibly immense and could catch the tiniest of details. Even a tiny little ant could be sensed by him clearly.

Therefore, Merlin finally found a trail of clues after investigating with his Mind Power.

"Up!"

Merlin reached out a finger. His spell immediately transformed into a giant hand that violently gripped onto the valley in front of him.

Hum.

Above the valley, a strong rumble erupted. Then, a series of runes flew out in a futile bid to resist Merlin's spell-conjured hand. However, Merlin's Four-Elemental Wizard Heart was already comparable to a Great Legend's or perhaps as powerful as a Legend. These Runic Magic Circles were unable to stop him at all.

Hence, the Runic Magic Circles flashed dimly and was instantly crushed by Merlin's spell-conjured hand. With that, the true appearance of what lied beneath the valley was revealed. It was an artificially constructed passage. Outside the passage, there were some large stone carvings. The stone carvings were originally covered with dense runes, but all of them had been crushed by Merlin earlier.

"Ozmu is here? Well, let's take a look at the mysterious Ozmu!"

Merlin was also filled with curiosity at Ozmu. This Spell Caster organization was extremely mysterious and had a longstanding history. They would recruit genius Spell Casters around all corners of the world and were completely unafraid of offending any of the large Spell Caster organizations.

If not for Ozmu's obsessive recruitment of prodigy Wizards, the battle with the southern Spell Caster world would not have erupted. Perhaps the factions and distribution of the entire Spell Caster world would have been drastically different.

"Wizard Tamo, how much do you know about Ozmu?"

Merlin asked Wizard Tamo as he eyed the huge passage.

Wizard Tamo frowned a little. The contract between him and Ozmu only prohibited him from revealing the location of Ozmu Headquarters which he did not breach at all. Merlin had found Ozmu Headquarters using Kleis' beacon ring.

Therefore, Wizard Tamo did not hesitate further and answered, "Wizard Merlin, there might have been an influx of Great Wizards into Ozmu in the recent years, and we are all able to enter Ozmu Headquarters, but in reality, our understanding of Ozmu is not more than outsiders. The core secret of Ozmu is known only to the original four Ancient Great Wizards of Ozmu. It's possible that Kleis might have found out about Ozmu's secret upon becoming the First Elder, but we definitely don't know anything."

Merlin crinkled his forehead. Wizard Tamo actually did not know much about Ozmu. There were so many Great Wizards, yet they were all not privy. In that case, it indicated Ozmu's distrust towards these Great Wizards.

Alternatively, it could be that Ozmu's secret was so astounding that it could only be revealed to a selected few.

"Who are the four Ancient Great Wizards of Ozmu?" Merlin continued to ask.

"Ozmu originally had four Ancient Great Wizards, but two of them had died in previous battles. There are only two left, but these two Ancient Great Wizards are truly formidable. In the whole of Ozmu, they are only inferior to Kleis! We guess that they must be at the level of peak Great Wizards. They are Great Wizard Savaron and Great Wizard Terian respectively!"

Merlin nodded. These two ancient peak Great Wizards were the real core of Ozmu. They were the ones who controlled Ozmu's true secret.

It was these Ancient Great Wizards who were controlling the entire Ozmu before Kleis had not become the First Elder.

"Interesting. Let's go inside. No matter what kind of secret Ozmu is hiding, it's useless now…"

With that, Merlin led the way and stepped into the pitch-black passage. After a moment of hesitation, Wizard Tamo and Wizard Gilles eventually followed him inside.

As for Yulais, she obeyed Merlin's instructions and stood guard outside the passage with the three-headed dragon.
