The female Wizard looked at Merlin, and laughed softly. "Of course, you can. However, that requires Dispelling Water! Dispelling Water is only produced in a strange dimension and is controlled by a certain Great King. Every bit of Dispelling Water costs a fortune! However, once it's consumed, the fused Pandora Demon Ability in previous spells can be removed, and you can re-cultivate stronger Pandora Demon Abilities!"

Merlin's eyes brightened. He had never imagined that there would be such a miraculous treasure. At present, his most obvious weakness was his fused Pandora Demon Abilities. The fused Pandora Demon Abilities he found in the Kingdom of Blackmoon were generally not that strong. There were some that were not even perfect, and had many defects.

If he had Dispelling Water, he would be able to re-cultivate Pandora Demon Abilities. At that time, this obvious weakness would become an advantage, and he would be no inferior to the genius Wizards who were taught by Great Legends since childhood.

"How many elemental crystal stones does Dispelling Water cost?"

Merlin asked softly. If the price was appropriate, he would not mind using Dispelling Water to re-cultivate Pandora Demon Abilities.

"Dispelling Water is costly but it's extremely worthy. Each type of Dispelling Water only requires ten million elemental crystal stones! If you use Dispelling Water and re-cultivate your Pandora Demon Abilities, I believe that the power of your spells will be greatly improved!"

The female Wizard said enthusiastically. However, no matter how passionate she was, she could not hide the high cost of Dispelling Water.

Ten million elemental crystal stones were only enough to buy one type. If Merlin wanted to dispel the fused Pandora Demon Abilities of his Six-Elemental spells, he would need six bottles of Dispelling Water, which was at least six million elemental crystal stones. That was an astronomical sum.

After all, even those Great Legends only had about ten million elemental crystal stones in their families. Many top Great Wizards would only have ten million elemental crystal stone after accumulating them for hundreds of years. Wizard Luce, as a ninth-level Spell Caster, had only accumulated a million or so elemental crystal stones over hundreds of years, not even two million.

However, one bottle of Dispelling Water cost ten million elemental crystal stones. Who were they selling to?

Great Wizards and above Spell Casters no longer needed Dispelling Water to cultivate their Pandora Demon Abilities. The only Wizards who could afford the price were Honoured Legends above top Great Wizards. However, Dispelling Water was of no use to them.

The Spell Casters who wanted to buy Dispelling Water to re-cultivate their Pandora Demon Abilities were not able to afford it, but it was still being sold at such an exorbitant price. Merlin wondered how Dispelling Water could be sold.

Seeing Merlin still remained unmoved, the female Wizard hurriedly explained, "The price of ten million elemental crystal stones is already quite cheap. After all, the last time we auctioned off Dispelling Water, one bottle fetched twelve million elemental crystal stones. The truth is, most of these bottles are bought by Honoured Legends. If they took a fancy to a disciple, they can buy Dispelling Water to let their disciples re-cultivate stronger fused Pandora Demon Abilities.

Merlin nodded. That was also a possibility. Nevertheless, looking at the price tag, even if his heart was moved, he had no other thoughts. He could not afford such a steep price at all.

"Forget it. Just collect these items for me."

Merlin told the female Wizard. He could still afford these rare items, but Dispelling Water was far beyond Merlin's capability.

"Very well, please wait a moment!"

The female Wizard was slightly disappointed, but she did not hold many expectations in the first place. After all, not everyone could afford Dispelling Water. It would be considered lucky to sell one bottle in ten years.

After a moment, the female Wizard took out a Spatial Ring containing some of the rare items Merlin needed.

"These rare items aren't that expensive, and only cost a total of three hundred thousand elemental crystal stones. As for the remainder, our Pavilion of Rarities has expunged them, so the total is only three hundred thousand elemental crystal stones."

"Three hundred thousand elemental crystal stones? That's not expensive!"

Merlin also knew the approximate price of these rare items, so he happily took out three hundred thousand elemental crystal stones. Before he left, the female Wizard did not forget to make one final push, and said gently, "Dispelling Water can dispel fused Pandora Demon Abilities even before there's a fused Spell Model. If you need it, the price can still be negotiated. The price of every bottle of Dispelling Water can be decreased by one million elemental crystal stones!"

Merlin smiled but said nothing as he knew the steep prices of Dispelling Water. However, no matter how high it was, it would at least be eight million elemental crystal stones. This was not a small sum for any Spell Caster.

As for Merlin, he had dropped that thought long ago.

After leaving the Pavilion of Rarities, Merlin needed to find a safe place to construct spells and try to rise to a seventh-level Spell Caster. Thus, he said to Wizard Luce, "Bring me to a safe residence!"

Wizard Luce nodded and said, "Generally, everywhere in the Shkedu Dimension is safe. No one dares to disobey the rules!"

Thus, Wizard Luce brought Merlin to a secluded courtyard. Merlin temporarily stayed at the place for a month and spent twenty thousand elemental crystal stones. Although it was considered costly, the environment was good.

"Wizard Merlin, I live not far from here. If you need anything, please don't hesitate to find me!"

Wizard Luce had accompanied Merlin for most of the day, so when Merlin had settled down, he quickly turned around, and left.

Merlin returned to the house, appraised the place, and casually sat down.

His current Mind Heart had already reached the Eighth-level, and his Mind Power was also comparable to some ordinary Ninth-level Spell Casters. Logically, it was enough to let him construct all Seventh-level spells.

However, whether he could really construct them, he had to simulate a Seventh-level Spell Model before saying for sure!

Thus, Merlin silently activated the Matrix. Since the Matrix had absorbed too many Maxims in Legend Zado's Maxim Subspace, its storing energy could be said to be terrifying. It would not be a problem to derive all Seventh-level spells.

"Matrix, derive seventh-level Darkness-type spells!"

Merlin let the Matrix derive Seventh-level Darkness-type spells first. After all, Darkness-type spells required the most amount of Mind Power. Merlin was also confident that his current Mind Power would be able to construct all Seventh-level spells.

The Matrix started rapidly deriving the spells, and its storage energy also started to decrease. The special energy needed to derive Seventh-level spells was at least several times more than for Sixth-level spells.

"Beep, derivation completed!"

Very quickly, the Matrix had completed its spell derivation. Merlin quickly looked at them.

Deriving Darkness-type spells have always been more difficult. Perhaps it was because the number of Darkness-type spells in the Matrix's database was lesser hence, the Darkness-type spells derived were also lesser.

However, there were still a couple of perfect-grade spells with one hundred percent compatibility.

Merlin chose one of them. Since he had the Matrix for deriving spells, he did not have to worry about the process at all. What he needed to do now was simulate the Spell Model in his Awareness.

After spending three days, Merlin finally succeeded simulating the first Seventh-level Spell Model. The moment the simulation succeeded, the surrounding Darkness elements seemed to turn into a viscous liquid, and enveloped Merlin.

Merlin clearly felt that the Seventh-level spells were different from the spells from before. It was a faint feeling of a deeper understanding of the Darkness element.

"So, Spell Models have this function as well. It can help in comprehending the essence of Elements?"

Merlin muttered under his breath while thinking carefully.

The Spell Caster system had existed for a long time. Although the Molta Empire collapsed more than three thousand and six hundred years ago, that did not mean that the Spell Casters only had a history of around three thousand years.

The Molta Empire was simply the era where the Spell Casters were at their most brilliant in the Glorious Land. Before that, Spell Casters could have already appeared for ten thousand years.

Over a long period of time, countless Spell Casters had almost completely perfected the Spell Caster system. Merlin had always thought that the purpose of a Spell Model was to absorb and transform Elements into magical power before casting the spell and unleashing great destructive power.

However, it was not until simulating a Seventh-level spell now that Merlin realized the true purpose of a Spell Model was to help Spell Casters slowly comprehend the essence of Elements.

The Spell Casters also slowly formed a system from scratch. If an ordinary Wizard wanted to directly comprehend the essence of Elements, how difficult would that be? It could not be ruled out that such Wizard did not exist, but they were few and far in between, and there might not even be one in ten thousand years.

Therefore, most Wizards had to gradually understand the essence of Elements through constructing Spell Models one step at a time, following the Spell Models as they grew stronger, and construction became more complicated.

By the time they construct Ninth-level Spell Models, most Spell Casters would have a certain understanding of the Elements. Those with slightly stronger comprehension would be able to fuse Spell Models, and become a Great Wizard. Furthermore, they would be able to completely comprehend the essence of the Elements, condense Maxims, and become Great Legends!

Compared with Spell Models below the Seventh-level, Seventh-level Spell Models had a qualitative improvement. Merlin immediately understood the real function of the Spell Models.

Of course, Merlin did not understand much about the Elements. He had just realized the use of Spell Models, and he had to slowly increase his comprehension. However, he roughly measured the Mind Power needed to simulate Seventh-level Darkness-type Spell Models, and found that with his current Mind Power, he could completely simulate six Seventh-level spells.

Thinking of this, Merlin stopped hesitating, and let the Matrix begin to derive the remaining five Seventh-level Spell Models.

Day by day passed, and after around twenty days, Merlin's body trembled, and emitted an intense Elemental fluctuation that carried an "oppressive" force.

Seventh-level… In the Shkedu Dimension, Merlin had finally become a Seventh-level Spell Caster!
