"Promise?"

Wizard Sammir went blank for a moment, then slapped his forehead as if he just remembered something. "I was too excited when I heard that you succeeded in making Edro Potion, so I forgot all about it. I've bothered that old man for almost half a month and even gave him my Mithril Alchemy Technique in exchange for this hundred years' ice bone marrow."

"Swish!"

Wizard Sammir said as he took a large sealed glass container from his ring. The thick glass container was the size of a washing basin and was completely sealed off. In it was a crystal clear, pale-white ice.

Merlin squinted his eyes. He had seen many glass containers such as this in the Resource Tower. Having such a delicate design, the thick glass containers were rare alchemy products. It would take at least hundreds of contribution points to exchange for them. The glass containers cost about the price of a normal casting tool.

At this moment, the glass container was only used to contain a single piece of crystal. Without a doubt, that was the hundred years' ice bone marrow which Merlin had yearned to have.

Wizard Sammir laughed. "This is the hundred years' ice bone marrow. That old man has hidden this away for many decades like a precious treasure. If the old man hasn't long for my Mithril Alchemy Technique for quite some time, I'm afraid that he won't give this item to me easily."

"Wizard Sammir, you can check if this is Edro Potion."

After seeing the hundred years' ice bone marrow in Wizard Sammir's hands, Merlin directly handed the freshly-made Edro Potion to Wizard Sammir. Thereafter, Wizard Sammir also handed the ice bone marrow to Merlin.

Although the item was contained in a thick glass container, it still gave off a chilly aura.

"Haha. This is indeed Edro Potion!"

Suddenly, Wizard Sammir laughed. He carefully checked the potion made by Merlin. The potion was no different than the description written in the potion formula – this was indeed Edro Potion.

However, the true effect of the potion could only be known until he had taken the potion. Wizard Sammir seemed to get extremely impatient by now, so he kept the potion and said to Merlin, "Wizard Merlin, I shall excuse myself to take this potion. After my Spell Models have stabilized, I'll visit you to deliver my thanks again!"

After saying that, Wizard Sammir brought the Alchemy Creature with him and left rapidly.

"Hu…"

Wizard Burton and the black-robed old man both heaved a long sigh of relief. They congratulated Merlin. "Congratulations, Wizard Merlin!"

Even though they did not know what was the purpose of Merlin having the hundred years' ice bone marrow, they realized that the item was extremely precious just by the looks of that exquisite glass container.

Merlin glanced at the hundred years' ice bone marrow in the container, stirred with excitement. Wizard Sammir's matter was considered to be solved at this moment. He could finally begin to make Phantasmal Magic Potion and Blueberry Potion to improve his Mind Power.

Hence, Merlin explained briefly to the black-robed old man and Wizard Burton, then returned to his room to continue the potion-making for his Mind Power.

…

After a month, a smile surfaced on Merlin's face as he gazed upon the seven potions which he successfully prepared.

During this period, Merlin had been making potions non-stop. He had a total of twelve sets of potion materials for Phantasmal Magic Potion which resulted in four successful potions. On the other hand, he had a total of nine sets of potion materials for Blueberry Potion which resulted in three successful potions with a success rate of thirty percent! 

The effect of Blueberry Potion was slightly weaker than that of Phantasmal Magic Potion, so he took the three Blueberry Potions beforehand. At once, his Mind Power surged.

However, along with the continuous usage of the same potion, the effect of increasing Mind Power also gradually weakened. However, Merlin's Mind Power still rose by a large margin.

Following that, Merlin planned his consumption of Phantasmal Magic Potions. He believed that the effect would be much stronger than Blueberry Potions.

Thus, in four days' time, Merlin took a bottle of Phantasmal Magic Potion each day and his Mind Power rose at a rapid speed. His Mind Power had almost increased by two-fold.

There was an increase in quality as well. Merlin's current Mind Power had finally reached the maximum of a Second-level. There would not be any problem for Merlin to construct Frigid Ice or Dark Light Realm.

However, if he wanted to construct Frigid Ice and Dark Light Realm at the same time, Merlin's Mind Power was still insufficient. The Mind Power needed for Dark Light Realm was simply too much. With Merlin's current Mind Power, it would be fine for him to construct the spell, but it would be difficult for him to continue constructing Frigid Ice thereafter.

Although Frigid Ice's Spell Model was complicated, the consumption of Mind Power was relatively lesser than that of Dark Light Realm. If he constructed Frigid Ice, Merlin's Mind Power could even support two more First-level spells which were relatively simple to construct.

Moreover, Merlin now possessed the hundred years' ice bone marrow. Only after he constructed Frigid Ice, he could cultivate Pandora Demon Ability with the hundred years' ice bone marrow.

Therefore, without hesitating any longer, Merlin had come to a decision. He would construct Frigid Ice first; if he had Mind Power left, he would continue to construct the Spell Models of Wind of Freedom and Thunderlight Ball.

When his Mind Power had reached the Third-level in the future, Merlin would once again consider constructing Dark Light Realm. After all, Merlin was a Six-Elemental Spell Caster. Each of his Spell Model consumed a large amount of Mind Power. Besides, Merlin's spells were all First-level spells; the slightly complicated and stronger ones would take up a horrendous amount of Mind Power.

The case was true for Dark Light Realm since the Mind Power it consumes would be enormous. Of course, Merlin's overall ability would rise significantly if he constructed Dark Light Realm.

Merlin decided to construct Frigid Ice first, so he calmed himself and cleared his mind of chaotic thoughts. Thereafter, he immediately initiated the Matrix.

"The Matrix, begin analyzing First-level spell, Frigid Ice!"

"Beep. Mission created. Analysis begins!"

Merlin was long familiar with the process of reconstructing a brand new Spell Model by using the Matrix. Thus, with a series of instructions, Merlin finally chose the best Spell Model in terms of compatibility, stability, and power.

Hence, an extremely complicated Spell Model quickly appeared in Merlin's head.

Frigid Ice was a complicated spell to begin with. Other than Dark Light Realm, it was the most complicated spell Merlin had ever constructed amongst all other spells. Naturally, it contained immense power as well.

To construct such a complicated spell, it would be an impossible task if he did not have strong Mind Power or the compatibility was not high. Even simulating the Spell Model in his Awareness would bring him endless trouble.

Luckily, Merlin had a strong Mind Power now and could completely support the construction of such a complicated spell, Frigid Ice. Moreover, he also possessed the Spell Model with the highest compatibility as analyzed by the Matrix. The most difficult part in constructing Spell Models to ordinary Spell Casters was now a piece of cake to Merlin.

Now, he only needed to keep calm, be patient, and slowly simulate Frigid Ice's Spell Model in his Awareness.

The simulation process had gone on for a long period. Almost two days had passed when Merlin's Awareness suddenly quivered. At once, a brand new Spell Model appeared in his Awareness.

He had succeeded in constructing Frigid Ice's Spell Model!

At the same time, Merlin felt a chill down his spine. He could clearly sense that Frigid Ice's Spell Model was frantically absorbing Ice Elements externally.

Once the Spell Model had been constructed, it would automatically absorb the Elements externally and turned the Elements into Magic Power, which was stored in the Spell Model. However, the process took a long time, so Merlin used some Ice elemental crystal stones to speed up the rate of Magic Power accumulation in the Spell Model.

Following that, Merlin continued to construct the spell, Wind of Freedom.

The Mind Power needed to construct Wind of Freedom was much lesser than that of Frigid Ice. Hence, Merlin simply took less than a day to construct it. In addition, his Mind Power appeared to be able to support more spell constructions.

Finally, Merlin decided to construct Thunderlight Ball.

Thunderlight Ball's Spell Model was about the same as Wind of Freedom. The Mind Power it required was far less than that of Frigid Ice, so Merlin still took less than a day to construct Thunderlight Ball's Spell Model.

Merlin had continuously constructed three First-level spells. In his Awareness, he now possessed the First-level spells – Furious Flame, Wind of Freedom, Frigid Ice, Guardian Monument, and Thunderlight Ball!

Amongst his Six-Elemental spells, Merlin had already constructed five of them except for the last First-level spell, Dark Light Realm.

Once he successfully constructed Dark Light Realm, Merlin would become a First-level Spell Caster. He did not need to worry about getting expelled from the Dark Magic Region as he could reach the conditions of the Dark Magic Region.

However, Dark Light Realm was simply too complex and required immense Mind Power. With Merlin's little Mind Power left, he had no way of constructing Dark Light Realm, so he continued improving his Mind Power.

Merlin did a slight estimation of this matter. When his Mind Power had reached the Third-level, he could construct Dark Light Realm confidently.

For the time being, Merlin began to speed up the rate to increase Magic Power of his Spell Models with elemental crystal stones. After the Magic Power of the Spell Models could support a dozen casts at once, Merlin finally stopped utilizing the elemental crystal stones.

After all, the consumption was too much to handle if he kept increasing his Magic Power with elemental crystal stones. Meanwhile, he could release a dozen casts at once for each spell – this was sufficient to support Merlin in facing ordinary battles.

"Swoosh!"

A giant glass container suddenly appeared in Merlin's hands. In it was the hundred years' ice bone marrow he had yearned for.

"Frigid Ice is quite stable now. It's time to cultivate the Demon Ability, Glacial Finger!"

At this point in time when he was about to cultivate Glacial Finger, Merlin was overwhelmed with excitement. He was nowhere this worked up when he constructed Frigid Ice and other spells.

After a moment, Merlin took a deep breath to resume his calmness. Then, he opened the sealed lid on the glass container in a sudden motion. At once, a chilling aura leaked from the thick glass container like wisps of white smoke.
