In the Inception Dimension, Merlin's Mind Power had already reached the peak of the Eighth-level. Considering the capacity of his Mind Heart, his Mind Power could no longer be rivaled by an average Great Wizard.

Upon reaching the level of Great Wizard, all the Spell Models would be combined into one. Therefore, the Spell Casters no longer had any need for Mind Power. Besides the Mind Power Masters, no one else would waste their time to cultivate Mind Power.

Upon becoming a Great Wizard, every Spell Caster would generally invest all their effort into consolidating a Maxim in order to become a Great Legend! Only the Mind Power Masters would continue to strengthen their Mind Powers in hopes of perfecting the Mind Power system and possess powers comparable to a Great Legend.

As such, an average Spell Caster's Mind Power was not very powerful. With Merlin's Eighth-level Mind Heart and peak Mind Powers, it was more than sufficient to construct all the Eighth-level spells.

Constructing spells was already a familiar path for Merlin. In the remaining time, while searching for the Saitu Dimension with Alcra, Merlin was also using the Matrix to derive spells.

Once all the Eighth-level spells had been derived, Merlin took a look at the energy stored in the Matrix. It had been consumed almost by half but there was still a little over half remaining, which should be enough to derive the Ninth-level spells. In other words, Merlin would no longer have to worry about deriving spells.

According to Merlin's deduction, Ninth-level spells would be the final spell he would construct using the Matrix. Once he had constructed all the Ninth-level spells, the next step would be combining his Spell Models into one to become a Great Wizard. In that case, the ability of the Matrix to derive spells would be rendered useless.

"Alcra!"

Merlin suddenly stopped Alcra.

Alcra turned around, and looked at Merlin questioningly. They had been flying for a long time but still did not find the Saitu Dimension.

Merlin did not hide anything from Alcra and explained, "Alcra, recently, I've been preparing to construct some spells so I might need your help to keep guard. Once I finish constructing the spells, we'll resume our search for the Saitu Dimension."

"Construct spells? You're going to level up?"

Alcra had been associating with Spell Casters for quite some time so naturally, he knew some common knowledge about Spell Casters. Constructing spells was a road that had to be taken by Spell Casters in order to become more powerful. Moreover, the reason that the Spell Casters were able to rise into one of the most powerful civilizations in the Void Zone so quickly was also attributed to their unique spell construction system. As long as someone had the right qualifications and suitable talent, they were able to construct Spell Models, thus giving rise to many powerful Wizards.

Therefore, the Spell Caster civilization was able to become so powerful despite entering the Void Zone only three thousand over years ago.

"Yes. In fact, I could have constructed the spells and level up in the earlier dimension but because of some other considerations, I did not level up."

Merlin did not tell Alcra everything. If only he had constructed the Eighth-level spells back then, supported by his four-elemental spells, he could have perhaps achieved the level of a preeminent Great Wizard.

At least, he would have been able to inflict some damage on Luca, Nestia, and the others. Perhaps, Alcra's nine Tree Saplings would not have been destroyed. Nevertheless, there was no use saying that now. Merlin had also learned a lesson, which was to improve his abilities as soon as possible. This way, it would prevent him from being underpowered when they had found the Saitu Dimension, and become Alcra's burden.

"Okay, you can construct your spells at ease. I'll protect you. Even should a preeminent Great Wizard approach us, it would take some time to break my protection."

Alcra was naturally pleased. Any improvement in Merlin's abilities would greatly benefit their expedition in the Void Zone. Now that the two of them had joined forces to act together, Merlin becoming more powerful was of course better.

"Rumble."

Thereafter, Alcra revealed his true form, which was an incomparably massive tree. The tree stood in the middle of the Void Zone, its sprawling canopy covered an entire region while countless thick roots wrapped themselves securely around Merlin to protect him.

Merlin also felt very secured on the inside, so he began to construct spells peacefully.

Simulating a spell model was a walk in the park for Merlin since he was familiar with it. The point of reference for every spell was one hundred percent compatibility, which would guarantee that the constructed spells were perfect-grade spells.

With every perfect-grade spell, they would help Merlin become more powerful when he had combined Spell Models in the future. The more perfect-grade spells he had, upon becoming a Great Wizard, Merlin might be able to become a demonic genius who could challenge past his own level. Even as a Great Wizard, he could possibly rival a Great Legend. This was considered a shining star among all the civilizations as well as one of the most powerful geniuses.

If Alcra could reconsolidate the nine Tree Saplings and level up into an upper rank Tree Folk, then he would become one of the most powerful geniuses among the Tree Tribe. This was because as an upper rank Tree Folk, he could rival a Great Legend.

Therefore, when choosing a spell, Merlin would select one with a hundred percent compatibility even if its power was slightly weaker. Nevertheless, perfect-grade spells generally packed a highly powerful force.

Over time, Merlin constructed one spell after another, causing the aura on his body to become stronger and stronger. Due to the power of the Eighth-level spells, they took a long time to be constructed, far exceeding that taken by the Seventh-level spells.

Moreover, in the Void Zone, there were no elements, hence Merlin had to use elemental crystal stones to replenish his Magic Power. The level of Magic Power required by the Eighth-level spells was astounding. Every type of spell consumed nearly a hundred thousand elemental crystal stones.

Six-Elemental spells consumed nearly six hundred thousand elemental stones just to replenish Merlin's Magic Power. In fact, Merlin began to regret constructing spells in the Void Zone because it had consumed too many elemental crystal stones. He would rather do it in a dimension with elements, and use one or two years to slowly replenish his Magic Power.

After an unknown period of time, Merlin slowly opened his eyes. Feeling the intense Magic Power coursing through his body, a sense of power came unbidden.

The transition from the Seventh-level to the Eighth-level might seem like a minuscule improvement but in reality, Merlin's abilities soared from a peak Great Wizard to a preeminent Great Wizard.

Based on Merlin's guess, the power of his spell fusion should almost reach the level of a preeminent Great Wizard. This was a substantive improvement. The difference between a peak Great Wizard and a preeminent Great Wizard might seem negligible but was an issue of limitation.

A peak Great Wizard could be achieved by any Spell Caster with some talents but a preeminent Great Wizard could not be achieved unless at least one's ability had reached his furthest limit.

Merlin, for example, had numerous perfect-grade spells and the most powerful fusion Pandora Demon Abilities but this was not enough to become a preeminent Great Wizard. Only by adding the Four-Elemental Spell Fusion, he was barely able to possess the abilities of a preeminent Great Wizard. Of course, compared to Alcra, Luca and the others, there was still a considerable gap.

"Merlin, are you awake?"

Alcra had been protecting Merlin for nearly a year, and had been watching him almost all the time. Initially, Merlin's body did not exude any aura that felt threatening to him but as time passed, and Merlin constructed his spells, Alcra could sense a looming aura that made him feel slightly threatened.

"Alcra, thank you for almost one year of protection. I've successfully constructed the spells and become an Eighth-level Spell Caster!"

Merlin hid almost nothing from Alcra so Alcra knew that Merlin was only a Seventh-level Spell Caster, who now became an Eighth-level Spell Caster.

"An Eighth-level Spell Caster? I wonder how much further your abilities have improved…"

There was a faint trace of curiosity in Alcra's voice.

"My abilities? Why don't I try it out?"

Alcra was thinking along the same lines so he laughed aloud. "Haha, no problem. The Tree Folk's defense is quite strong. Unless you lure me into an illusion using your Mind Power Master abilities, you shouldn't be able to cause any harm to me. Let's see how your abilities have changed! Come on, use your newly constructed spells and wield your most powerful force!"

There was an emerald glow on Alcra's massive tree body that made him look lush and vibrant. It appeared that Alcra had not remained stagnant throughout this period but gradually recovered.

"Very well." Merlin was also eager to try his abilities. He knew the extent of Alcra's defense, so he did not hold back at all. He stretched out a pale hand as the elements fluctuated wildly around him.

Flame, thunder, gale, and ice crystals – the Four-Elemental spells were fused together by Merlin, and he compressed them continuously.

"Go."

Sensing the critical point, Merlin stretched out his hand and pushed. A ferocious Spell Fusion flew toward Alcra in an instant, and exploded upon impact with the huge shield woven together by Alcra.

The violent shock wave caused even Merlin to stumble a few steps backward whereas Alcra's tree body was quivering gently. Soon, however, the movement calmed.

"Haha, not bad, not bad. You're probably almost comparable to a preeminent Great Wizard now! Great job, Merlin, really great job. Now you have the ability to harm the most preeminent Great Wizards. With the addition of your Hallucinating spells, you would be extremely formidable!"

Alcra was a little shocked in his heart. He did not expect that Merlin's attack was almost comparable to a preeminent Great Wizard already. This was a substantive transformation that was very critical. Originally, with the complement of Hallucinating spells, Merlin was already quite impressive. Now, following the improvement of his spells, he was not only impressive but intimidating.

A smile appeared on Merlin's face. His prediction of the spell fusion's power had not been wrong. Right now, he was an Eighth-level Spell Caster with the powers to cause harm to a preeminent Great Wizard. Undoubtedly, it would further secure his expedition in the open territory.

"Very well. Alcra. Let's continue to search for the Saitu Dimension."

Despite becoming an Eighth-level Spell Caster, Merlin of course, did not forget their main objective, which was to locate the Saitu Dimension. According to the size of the dark territory marked on the dimension map, they had only searched a very small area.

Since Merlin's abilities had undergone a big improvement, they widened their search range. Each of them searched an area by themselves but not too far apart from one another. As long as there was any movement, both sides would be able to sense it.

In the pitch-black Void Zone, one year, two years, three years had passed…

Merlin and Alcra had searched for nearly five years but the lonely and boring days did not deter their strides. Finally, Alcra was the one who discovered a cloud-like dimension within the open territory.

The two of them compared it to the dimension map. This was a dimension that had not been marked on the latest dimension map, so it was likely that it was the Saitu Dimension that Merlin and Alcra had been searching for.

"We've finally found it! Nevertheless, we must be cautious. I'm going to check if Legend Saitu's mind imprint still exists!"

Although Merlin was excited, this was still a dimension occupied by Wizard Saitu. Merlin was not sure whether Wizard Saitu was present, so he first needed to determine if there was a mind imprint.

If there was none, it would mean that the Saitu Dimension had once again become a masterless dimension.

Therefore, Merlin carefully mobilized his Mind Power, and extended it into the dimension.
