Merlin held the bowknot-shaped casting tool in his hands. It was one of the two casting tools that Wizard Bell had transfigured to work together.

The bowknot-shaped casting tool began to let off a warm energy. It seemed to have encountered another component.

It was important to note that the bowknot-shaped casting tool was an Assembled casting tool, which meant that it was made of multiple components to form one whole. Thus far, Merlin had only collected two components which then fused to form the bowknot-shaped casting tool.

When Merlin only had the first casting tool, the Bell Pendant, it had the ability to store spells. Once he paired it with another casting tool, it formed the bowknot-shaped casting tool and became an Enhancing casting tool. It was able to increase the defensive strength of his First-level spell Guardian Monument drastically, making it comparable to that of a Third-level defensive spell.

Now, the bowknot-shaped casting tool was transforming once more. It was clear that inside the ring of either Weiss or Riesen, was another casting tool that could be assembled with the bowknot-shaped casting tool.

Searching through both rings again, Merlin found a peculiar triangular casting tool. He took it out and immediately, the bowknot-shaped casting tool emitted a fierce bright light.

"It would seem that this casting tool is the third component to the Assembled casting tool!"

Merlin did not know if many components were left to be added to the Assembled casting tool, but he knew vaguely that with each addition, a completely new casting tool would form.

However, as a new casting tool would form, the original effects of the casting tool would immediately disappear. Merlin pondered for a while, he was unsure if he should fuse the third component and lose the effects of the bowknot-shaped casting tool.

Once assembled, it may no longer be an Enhancing casting tool and therefore would no longer be able to increase the strength of Merlin's Guardian Monument. This would greatly impact Merlin, despite his Offensive strength being powerful, he still lacked in Defensive capabilities, but with the Enhancing casting tool, this had not been that big of an issue.

"I already have the robe that can withstand Third-level spells, the Enhancing effects of the casting tool on Guardian Monument are not as important anymore."

Merlin weighed the pros and cons. The strengthened form of Guardian Monument was not as useful anymore. Moreover, if he increased his Mind Power slightly, he would be able to construct a Second-level spell.

If he constructed a Defensive Earth-type Second-level spell and strengthened it, it would be in no way inferior to the strength of a Third-level spell.

With that in mind, Merlin had come to a decision and was prepared to combine the bowknot-shaped casting tool and the third component together to form a completely new casting tool.

Merlin took a deep breath as he placed the bowknot-shaped casting tool and the triangular casting tool together.

Immediately, a bright light emerged from the bowknot-shaped casting tool and enveloped the third component with it.

Merlin could not see clearly what was happening in the bright light, but he knew that the two pieces had to be fusing together.

After half an hour, the bright light from the casting tool flashed quickly then dissipated. On the table lay an extremely glossy oval-shaped casting tool. On the top was a small eyelet, it was as if a string could be pulled through and it could be worn on one's chest.

Merlin picked up the new casting tool, it was still warm. However, the surface was a bit uneven as there were a few mysterious runes etched upon it.

There was no way to tell the benefit of this casting tool just by looking at it, it was best to use one's Mind Power to find out the true capabilities of this new casting tool.

Hence, Merlin shifted his Mind Power and examined the new casting tool.

"Boom!"

Merlin's Mind Power had just enveloped the new casting tool and immediately it was as though his Mind Power entered a vortex. It was transported to an unfamiliar space.

The space was pitch black, but Merlin's Mind Power was not affected, and he could clearly see his surroundings.

The space was very big and unlike the space within a ring. Merlin's Mind Power could sense a particular distinction, but he could not tell what it was exactly.

"Is this the effect of the casting tool?"

Merlin was curious, he did not expect this to be the function of the casting tool. Suddenly, a memory appeared in his mind.

The memory was very unexpected, it was almost as if it appeared out of thin air. The memory held information about the new casting tool.

It was clear that the memory and this casting tool were somehow related.

The information described the space created by the casting tool to be a place that could only be entered using Mind Power. It was a space that was able to simulate any spell or even Demon Ability.

Additionally, it had another benefit, it allowed Mind Power to exist independently inside and would eventually increase one's Mind Power.

Merlin was astounded. Although it was just a few bits of information, it was certainly something incredibly astonishing.

"This space is truly real! Spells and Demon Abilities can be simulated in this perfect space. One must have possessed incredible strength to be able to produce a space like this!"

Merlin was still in shock, even the Great Wizards could not master Spatial Strength. It would require the Runic Circles arranged by the Great Wizards to reach the extent of this space.

However, it would be impossible to control its Spatial Strength for even the slightest use. Many Spell Casters' rings already possessed a type of Spatial Strength, but this was quite common. Most of them were passed down from many generations before. Merlin had never heard of a Spell Caster organization that could transfigure a Spatial Ring.

Perhaps, there were only a few Spell Casters during the peak era who mastered Spatial Strength and transfigured the rings.

It would seem Wizard Bell was quite a complicated figure. Merlin had originally believed Wizard Bell to be a historical Great Wizard, but he was in fact, an even more powerful Great Alchemist.

Now, the three casting tools had assembled and formed a space. This was much more advanced than any Great Wizards' capabilities. Merlin could not even imagine how powerful Wizard Bell must have been. After all, Merlin knew that Wizard Bell was the most powerful Great Wizard.

The creator of the Dark Magic Region, Great Wizard Fidel, or even the creator of Sterling House, Great Wizard Sterling may have been powerful Great Wizards, but they could not master Spatial Strength.

The space did not depend on elements but instead obeyed an unknown law of strength.

"Let's test it to see if the Bell Space can truly simulate anything."

Merlin focused his Mind Power on the Bell Space and within a few moments a figure had formed to look exactly like Merlin.

"Construct a Spell Model."

Merlin's "Mind Power duplicate" immediately attempted to construct the Zero-level spell, Fireball.

"Ka-chak!"

Merlin's Mind Power duplicate had just tried to construct the Spell Model of Fireball but the duplicate collapsed immediately.

Merlin furrowed his eyebrows. He tried a couple more times, but like the first time, the Mind Power duplicate would immediately collapse. However, with each attempt, Merlin slowly began to realize the reason this had happened.

"Fireball may be a Zero-level spell, but it still requires a bit of Mind Power. Perhaps this is because my Mind Power in the space was too weak. It could not meet the Mind Power requirement of Fireball and therefore had failed."

This was Merlin's guess and so this time he increased the force and sent an incredible stream of Mind Power into the space.

Merlin's original Mind Power was only one percent of what he had now. It was just a mere fraction, but now, Merlin possessed Mind Power that could rival that of a Third-level Spell Caster. This one percent of Mind Power was able to construct the Zero-level spell, Fireball.

In reality, Merlin would have preferred to send through even more Mind Power into the space. However, during his attempts, Merlin had noticed a problem. Each time his Mind Power entered the space, it would decrease immediately. This meant that if the Mind Power Merlin sent into the space collapsed, it would truly disappear, and Merlin's Mind Power would eventually decrease into nothing.

If Merlin had dared to send a larger part of his Mind Power into the space, his Mind Power would immediately descend a level. Eventually, the Spell Model would collapse immediately.

Merlin realized this and did not take the risk of sending too much Mind Power into the space.

Merlin's Mind Power duplicate quickly attempted to construct the Spell Model of the Zero-level spell, Fireball, once more.

"Buzz."

This time, Merlin's body vibrated and soon his body began to fluctuate with faint Fire Element. This was constructed purely by his Mind Power duplicate.

Merlin's Mind Power duplicate had indeed constructed the Spell Model for Fireball, and it was no different to when Merlin constructed it outside the space.

Merlin realized the simulations in this mysterious space were realistic, he could not help but shout out, "I could use my Mind Power freely with the help of this space! Could it be possible to build Spell Models in advance? If I fail, it would not be life-threatening!"

Merlin had finally realized the true function of the space.
