Merlin had also just understood the rules in the Dark Magic Region from the words of the gray-robed Wizard. Spell Casters who had entered the Dark Magic Region would have their Dark Magic rings confiscated and sent out the Dark Magic Region if they did not become a First-level spell Caster within three years.

The sensuous and beautiful Laurinka before him had yet to become a First-level spell Caster although it seemed that three years were almost up. She would soon face the risk of being sent out the Dark Magic Region.

"Your Mind Power should have reached a high enough level to construct a First-level spell, right? How can it be that you've not yet become a First-level spell Caster?"

Merlin was somewhat curious. Laurinka, who was in front of him, might have a worse quality of Mind Power than Merlin, but in three years, her Mind Power had already grown to a level comparable to that of a First-level spell Caster. The only thing left was to construct a First-level spell.

There was a strange expression on Laurinka's face. She turned her head to look at Merlin weirdly before saying in a low voice, "My Mind Power is enough of course, but could it be that you don't know the most difficult part of being a Spell Caster is the construction of Spell Models?"

"Construction of Spell Models? How difficult is it? There are many Spell Models in the Dark Magic Region, and most of them have been created by powerful Spell Casters so their stability must be pretty good. So it should be rather easy to construct a Spell Model."

Merlin was in deep thought for a moment before speaking in a cold tone of voice.

"It's rather easy to construct a Spell Model?"

Laurinka glanced at Merlin with a deep look. Then, as though she had understood something, she shook her head helplessly, smiled bitterly and said, "Turns out you don't know, but yes, of course, you're a roaming Wizard, so naturally, you don't know the difficulties here. In fact, spell building is the most difficult because the Mind Power of every Spell Caster is different so the type of spell created is also different. Therefore, the Spell Model to be constructed has to be the one most suitable for oneself."

"Even the Spell Models created by the powerful Spell Casters aren't necessarily the most suitable. After obtaining the Spell Model, one would still need to take practical action and construct it in reality once more, according to one's own situation. Otherwise, at best, the construction fails. At worst, the Spell Model collapses and completely destroys the foundation."

Pausing, Laurinka gave Merlin a weird look before speaking in a low voice, "Don't tell me that you've never reconstructed the three Spell Models you've created, and have immediately simulated them in your Awareness?"

Merlin felt slightly startled. This was simply some general knowledge for many of the Spell Casters in the Spell Casters organization, but before Merlin had entered the Dark Magic Region, neither old man Etha's Spell Manual and the black-robed old man had mentioned this. They had thought that a Spell Model could be directly simulated in the Awareness as long as it was stable.

It was not surprising, then, that the Spell Models in the black-robed old man were unstable. Meanwhile, nothing had happened to some of the other Spell Casters who were using the same Spell Models.

It turned out that Spell Models could not be directly used. One still had to reconstruct them so that they would be suitable for the Spell Caster's actual condition.

Merlin thought about the Spell Models in his own Awareness. They had been constructed completely by the Matrix, so he did not know whether there were any hidden risks. Merlin immediately spoke to the Matrix in his heart, "Matrix, check the situation of how the Spell Models in my body are operating now."

"Beep, test begins... Test completed. The current Spell Models in your body are in stable operation."

"Check the data from the Spell Models constructed in the past."

"Beep, displaying data..."

Right away, large amounts of data appeared in Merlin's mind. There were the various kinds of data gathered from the construction of Fireball, Frost, and Earth Guard.

Merlin quickly searched and checked. Very soon, amongst the data, he discovered a segment of various data based on the "Master" that had been used to construct the Spell Models.

"Phew..."

Merlin gave a long sigh of relief. It turned out that, unbeknownst to him, his actual condition had already been inserted into the data of the Spell Models analyzed by the Matrix. This was also one of the advantages of having an "intelligent" quantum calculator.

Therefore, Merlin did not need to worry about whether there was anything wrong with the three Spell Models created by the Matrix.

Laurinka, who was standing on the side, saw Merlin's expression shifted and changed. She thought that Merlin was vexed about the three Spell Models he had constructed. Therefore, shaking her head slightly, she said, "Actually, you don't have to be so worried. You've already created three Spell Models, and although it's very likely that there are hidden risks, you can still slowly rectify them with great amounts of potions."

"Potion?"

Merlin gave a start in his heart, remembering the black-robed old man's exhortation. He was suffering from the torture of having unstable Spell Models and desired the Spell Model-stabilizing Potion greatly.

However, Laurinka did not explain more about the potion. She merely answered in general terms, "All of these are general knowledge. You'll slowly know more in the Dark Magic Region in the future. Let's go, I'm bringing you to see Wizard Leo."

Merlin nodded. He was still going to stay in the Dark Magic Region for at least three years, and there was no need for him to hurry. He could slowly understand more in the later days. Thus, following Laurinka from behind, he continued to walk forward.

On the way, all that Merlin could see were some towers. These towers were emanating strange fluctuations. In addition, some of the towers were very tall, so much so that the top of the towers could not be seen. Some of the towers were evidently very short, and he could see their pointy turret tops.

"Do all these towers have Runic Magic Circles arranged on them?"

With a sudden realization, Merlin noticed that the strange fluctuations from the towers were rather similar to those from the mysterious runes on the Dark Magic ring.

A strange look flashed across Laurinka's eyes. After that, she nodded and said, "It looks like you have quite keen senses to be able to notice the Runic Magic Circles on the towers. Back then, when I first came here, I hadn't discovered this. You're right, there are Runic Magic Circles arranged on these towers, indeed. Otherwise, how can ordinary buildings be constructed to be so high?"

"Only by arranging the mystical Runic Magic Circles, the towers can be kept from collapsing, and they can be built to be higher and higher. In relation to the towers in the Dark Magic Region, only intermediate Spell Casters, Fourth-level and above, are allowed to construct their own tower. The stronger the Spell Caster, the higher the tower he constructs."

Merlin looked around briefly. There were approximately fifty over towers that were standing tall and aloft in the entire Dark Magic Region. This meant that there were at least fifty over powerful Spell Casters who were Fourth-level and above.

Fifty-over Spell Casters, Fourth-level and above. This was a great power that Merlin was unable to imagine. The capabilities of the Spell Caster organization was, as he had expected, the greatest. Amongst some of the roaming Wizards outside, even a First-level spell Caster was extremely rare, let alone a Spell Caster who was Fourth-level or above.

Suddenly, Laurinka stopped in her tracks. She turned her head and gave Merlin a smile and said, "We've arrived. This is Wizard Leo's tower, and also where you shall be staying for the next three years."

Merlin lifted his head to see a grayish white tower before him.
