The Void Zone was immense, vast without boundaries, and there was no concept of space and time. No matter how fast one flew or how far one walked, one would never see its end.

Merlin did not know how long they had flown. He sensed that the Wind-type Magic Power in the Spell Model within his body was almost depleted. If he continued casting it, it would cause the Spell Model to collapse in the end. Thus, he could only stop for now, and use elemental crystal stones to replenish some Magic Power.

Fortunately, there was a huge number of elemental crystal stones stored in Merlin's ring. In the Spatial Ring, they nearly piled up to a hill. The number of elemental crystal stones was enough to sustain Merlin's free and aimless flight for decades.

Nonetheless, Merlin did not wish to fly on alone in this boundless Void Zone. He needed to locate a dimension.

On the other hand, Didimoss appeared undisturbed. He had spent over a thousand years alone in the Runic Magic Circle and had gotten used to solitude long ago. The current Void Zone was merely a change in the environment and was not that much different.

"Since there are no Elements in this Void Zone, it'll be hard for me to even construct a Spell Model. Once I construct it successfully, I'll have to consume a great number of elemental crystal stones to accumulate Magic Power."

Merlin had even considered constructing a Spell Model first. After all, with his current Mind Power, he could construct two Fifth-level spells. Nonetheless, he did not know how long he would roam the Void Zone, so elemental crystal stones were extremely precious. He would not use them lightly. As for spell construction, he would need to at least locate a dimension filled with Elements.

Merlin searched about aimlessly. Suddenly, he noticed a large, faint, bubble-like cloud of fog in a distant patch of darkness, which covered an entire region.

"What's this?"

Merlin felt a jolt of surprise. This was the first time he had seen something that was not just emptiness in the Void Zone – the first time something had changed. This caused him to feel a trace of anticipation in the midst of his astonishment.

"Let's hope that this is a dimension."

Merlin drew in a deep breath, following which his speed increased by a little. This fog was like a bubble. The area it covered was not large but it contained unfathomable depths. Merlin's Mind Power probed it in an investigative manner.

"Boom!"

Merlin's Mind Power had merely touched it lightly when he felt as if his mind was about to explode from the endless information flooding his mind. Thus, Merlin immediately withdrew his Mind Power as soon as he can. Although it was full of danger, his expression revealed his elation.

"It's a dimension – a colossal dimension, one filled with living beings!"

From the information he had obtained from the investigation with his Mind Power, Merlin acquired a few general facts regarding this dimension. However, it was too vague and in a disorderly manner hence he could not discern any useful facts. He merely knew that this was a dimension filled with living beings.

"Merlin, did you get a clear perception of it? If this is a dimension that no Spell Casters cultivated before, then you have no choice. Most uncultivated dimensions like these are inhabited by natural gods. Once a god discovers you, not even a Great Wizard would be able to escape!"

Conversely, the black cat Didimoss was not as overjoyed as Merlin. He had some understanding of dimensions. Of course, it must have been through the Great Wizard Fidel that he learned of some facts regarding dimensions.

Upon hearing Didimoss' warning, Merlin gradually turned solemn. It was true that there were countless dimensions in the Void Zone. Although Spell Casters had set foot in the Void Zone more than three thousand years ago occupying countless dimensions, the Void Zone was far too vast, and there were many dimensions which were not yet discovered.

These dimensions, undiscovered by Spell Casters, were generally inhabited by natural gods. These gods were mostly comparable to Legends. Even if they were slightly weaker than Legendary Wizards, they were able to contend against those Wizards for dominance over the dimension.

If Merlin rushed in recklessly and was discovered by a god, he would truly be in danger!

After a long period of deep thought, Merlin drew in a deep breath, and said in a low voice, "I've been in the Void Zone for so long, and it's not easy to encounter a dimension. I can't let this slip by me so easily, so I'll have to take a look inside no matter what."

Merlin had decided. Thus, his body flickered with vigorous Wind Element and he led Didimoss, quickly entering that gigantic bubble of fog.

An entire new dimension – Merlin's heart was filled with anticipation…

…

On a wide road, a blue horse carriage moved slowly. Behind the carriage, there were a few men dressed as Wizards yet they were riding horses. In general, the physiques of Spell Casters were weak, but these men dressed as Wizards had well-built bodies and were more like knights rather than Spell Casters.

Just as the blue horse carriage was about to pass through a small patch of forest, four Spell Casters wearing wide-brimmed Wizard hats suddenly emerged from the thicket on both sides.

These four mysterious Spell Casters blocked the path. The blue horse carriage stopped immediately, and the knight-like Spell Casters behind the carriage quickly galloped to the front, standing opposite the four Spell Casters who were blocking the middle of the road.

"Wizard Rucian, what's the matter?"

A woman's voice came from the blue horse carriage, after which the head of a noble lady poked out from within the carriage, frowning as she looked at the situation in front.

One of the horse-riding Spell Casters said in a low voice, "Honorable Lady Phillie, a few Spell Casters of unknown origin are blocking the road ahead. I'm afraid that my lady is their target."

"Hmm?"

Lady Phillie looked at the four Spell Casters before her and unexpectedly smiled as she said, "Honorable Wizards, if you're lacking anything, you can come to my Boulder City. The trade alliance in Boulder City is looking for powerful Wizards and will provide a decent pay. The trade alliance even has the precious potion materials that you want. If you're interested, I can recommend you. How does that sound?"

One could tell at a glance that Lady Phillie, with the appearance of a merchant, was worldly and knowledgeable. She was even able to talk about "business" with these Spell Casters who were clearly menacing.

"Tsk tsk, you really are the president of trade alliance in Boulder City. I've heard that Lady Phillie is savvy in business, squeezing the business of Tagan City to an extreme. Now, it looks like that's really the case!"

The Spell Caster at the center of those four Wizards spoke in a sharp, penetrating voice as if he was familiar with Lady Phillie's background.

Upon hearing what the mysterious Spell Caster said, Lady Phillie's face shifted slightly. With a darkened face, she said, "You're sent by Tagan City? Humph, Weston is really useless to resort to such a move. Even if I die, the declining fate of Tagan City will not be reversed!"

"I don't care about any grievances between you both. At the end of it all, we only need to kill you for Weston to fulfill his promise. Die!"

The four black-robed Spell Casters immediately cast their spells. The intense fluctuations of spells were evident. As for those Spell Casters who looked like knights, they quickly drew huge swords from behind their backs.

"Buzz."

The huge swords were in the hands of these "knights", whose hands emanated intense Elemental fluctuations. They were Spell Casters indeed, but they had another identity, which was formidable knights.

These were extraordinary melee Wizards. They had sturdy physiques, and the spells they learned were mostly Defensive spells or spells which had incredible destructive power within close range. Once confronted, they would rapidly rush toward their enemy, exterminating their opponents at close range.

Therefore, the instant the battle began, those melee Wizards quickly dashed at the black-robed Spell Casters in front. The Elemental fluctuations surrounding the melee Wizards were of the Third-level but if they got near enough, most Third-level Wizards were no match for them.

"Humph, are these the melee Wizards of Boulder City so well-known far and wide? They'll fall in a blow! Spark!"

Suddenly, the loose robe worn by the Spell Caster at the head began to flap in the still air. Waves of intense Elemental fluctuations were emitted, and wisps of flame even gradually ascended from his body.

"Fourth-level Wizard!"

In the horse carriage, Lady Phillie's face turned pale. In fact, she was also a Spell Caster but due to factors of talent, she was merely an Entrance-level Spell Caster.

Although she was merely an Entrance-level Spell Caster, she was very sensitive toward the spell fluctuations of Spell Casters. In a second, she was able to discern that the mysterious black-robed Spell Caster was a powerful Fourth-level Wizard.

There were only three Fourth-level Wizards even in Boulder City, and they usually did not make an appearance. The trade alliance would have to pay a huge price and invite them before they would undertake a task. Normally, they were simply receivers of the offerings of the trade alliance, enjoying the various resources provided by the trade alliance of Boulder City.

She did not think that this time, Tagan City would recruit Fourth-level Spell Casters to do the job. It seemed that they really wanted to put her in the ground. At this point, Lady Phillie, who had always been calm and cool, became nervous.

The flames on the black-robed Wizard grew and grew. As he looked at the melee Wizards who were constantly approaching, a cold smile broke out across his face. It might be that the melee Wizards of Boulder City had the upper hand when faced with Spell Casters of the same level but he was a Fourth-level Spell Caster. These melee Wizards were nothing in his eyes.

The black-robed Wizard stretched a hand in a gesture. Instantly, boundless flames formed a sea of fire, rapidly engulfing the bodies of those melee Wizards. The furious blaze began to burn violently.

These melee Wizards were incapable of withstanding the attack. The swords in their hands were burned to ashes while they unleashed pitiful cries.

The disparity between the Third- and the Fourth-level was extremely obvious. It was a disparity in essence! Otherwise, based on the power of trade alliance in Boulder City, they would not possibly employ only three Fourth-level Wizards to keep watch over Boulder City. It was because the asking price of a Fourth-level Wizard was far too high, and the trade alliance could barely afford three Fourth-level Wizards.

However, the three Fourth-level Wizards invited by the trade alliance could not possibly be used just for Lady Phillie's protection. Even though Lady Phillie was the president, Fourth-level Wizards would not carry out such tasks of personal protection. It would be humiliating to Fourth-level Wizards!

Thus, when faced with the slaughtering of this mysterious Fourth-level Wizard, Lady Phillie could do nothing at all.

"Mother, I'm afraid!"

From the horse carriage, another small delicate face peeped out. It was Lady Phillie's daughter. This time, Lady Phillie had brought her daughter to check on a business under the banner of the trade alliance. Initially, she thought that with the protection of a few Third-level melee Wizards, they would be very safe, yet she did not expect that they would still run into danger.

"Darling, don't be afraid. It'll be fine. Go back into the carriage. Don't show yourself."

After coaxing her daughter back into the carriage, Lady Phillie turned her attention once more toward the Fourth-level Spell Caster approaching her step by step. She opened her mouth to say something but felt a rush of powerlessness.

In a situation like this, she could not just neutralize the crisis in just a few words, unless the Fourth-level Wizards of Boulder City could make it in time. However, this was an impossible hope.

"Weston's target is me. As noble Spell Casters, please let my poor daughter go…"

Still, the mysterious black-robed Spell Caster gave no indication to what he had heard. The flames in his hand rose up higher and higher, burning in a rage, emitting a scorching heat.

An expression of despair came over Lady Phillie's face. She turned her face toward the sky and softly closed her eyes.

Just as she was closing her eyes lightly, she suddenly saw that in the sky, at an unknown time, a fireball had appeared. It grew bigger and bigger as it got nearer and nearer, trailed by a long tail of flame, whistling as it sped toward the ground…
