Jiwen's spell failed at the last minute, and shattered ice crystals scattered all over the ground.

Master Niels looked at Given's disappointed expression and smiled to persuade him. "Don't worry, the first thing to use is the crystal disk, there are always accidents. ”

Givens nodded and began a second attempt. But to his and Niels' expectations, Jivin's attempts failed one after another. Every time, when the ice arrow was about to take shape, it fell short. Even after Master Niels, who was also a hedron warrior, carefully taught Jiwen the essentials of using the crystal disk, he still failed.

"How so?" asked Givan puzzled.

"I've never seen anything like that. "Master Niels's face is very ugly, after all, this crystal disk was modified by him according to the measurement results of Jiwen, even if the craftsmanship is not perfect, either he cannot cast spells, or the casting effect is weak. There shouldn't be a failure halfway through.

"Otherwise, I'll modify the next crystal disk, which will take about three or four days. Looking at Given's increasingly disappointed look

But as soon as Jiwen heard the time, he shook his head. By then, the demon might have been at large, and Adelia had completely lost her admission to the Royal Summoning Academy. But if you don't change it, what will you do now?

Jiwen carefully analyzed, since the spell was about to take shape, it meant that there was no problem with the basic design of this crystal disk, but the failure of the last step showed that he was inconsistent with this design.

What's different about myself? Is it because I'm not an elf!

It suddenly occurred to Jiwen that the crystal disk needed to resonate spiritually with the user's body, and Master Niels's processing habits must have been based on the physical characteristics of the elves. He is the only human in this world, and there will naturally be an accident when he continues to use the elf's crystal disk.

If this is the reason, no matter how much Master Niels modifies it, he will not be able to solve this fundamental problem. It is impossible for Givens to reveal his true identity in front of Master Niels, let alone tell him that he is a human. Faced with this problem, Jiwen asked tentatively.

"Master Niels, could it be because of my special physique?"

"Special?" Niels looked at Jiwen, the Copperbeard did possess a void body and strange powers. But he wasn't an apprentice making crystal disks for the first time. Master Niels replied affirmatively to Givin: "I have already considered this when I modified the crystal disk. The graphics I carefully recorded at the time were the properties of your ability to channel magical energy. As long as you're an elf, even if your physique is a little weird, you should be able to fit the crystal disk. ”

When Jiwen heard this, his heart suddenly sank. He wanted to tell Master Niels that he wasn't an elf.

It seems that if this crystal disk continues to be handed over to Master Niels for modification, it will never be able to cast a spell on himself. If you want to succeed, you have to take another path, and finally Givens makes a difficult decision, and he asks about Niels.

"Master Niels, I want to adjust the crystal disk myself, can you guide me?"

Although Jiwen tried to lower his posture, a trace of displeasure still flashed on Master Niels's face. The meaning of Given's words seemed to be distrusting his technology. But this Mr. Copperbeard had helped him, and because of his embarrassment, he could not directly refuse Jiwen's request.

It is impossible to agree to Mr. Copperbeard's request. In the kingdom of Solland, it was impossible for Niels to teach a stranger outside the guild how to make and repair crystal disks, and the notebook given to Jivin at that time was already the limit of Niels. In the end, Master Niels had to utter a vague proverb, which was regarded as an answer.

"There is a legendary master who said that the crystal disk is a mage made of rock and metal, and it reflects the origin of magic, and Mr. Copperbeard seems to know the mysteries of magic, and you should gain something from understanding it. ”

"Oh, thanks. Givens was a little disappointed, and Master Niels still seemed to have a grudge against what he had just said.

It seems unlikely that he could be expected to teach himself directly. But it's okay this way, and I don't have to worry about Niels discovering his identity, so as not to make the city stormy. After figuring it out, Givens turned to asking, "Can I borrow an unused workshop?"

Now that Givens had no other choice, no matter what the outcome, he had to try.

Niels nodded, and led Givin to the workshop, where he glanced at Mr. Copperbeard from time to time. It seems that this mysterious Mr. Copperbeard is really ready to take on the challenge of repairing the crystal disk himself. Niels was already very curious, and he wanted to see what the result would be for this layman who didn't know anything about crystal disc manufacturing.

After thanking Niels, Givens entered the small, empty workshop, which was small but full of furnace tools. Jiwen sat down in front of the workbench, holding the crystal disk, and looked at it carefully. Unlike the last time it was damaged, the newly restored crystal disk was refreshing to Given, the various colored gems formed an exquisite spatial structure, and on the metal base, countless fine lines shuttled back and forth between the gems.

Given's sudden realization that the crystal disk seemed to resemble the mechanical labyrinth he had seen in the spellcasting illusion, and that the patterns and gems were somewhat similar to circuit boards on Earth. However, from the appearance, Jiwen can only analyze to this extent, and if you want to go deeper, you can only rely on books. So Jiwen carefully took the notes and the books out of the storage ring, and since Jiwen managed to stuff the magic sword into the storage ring, the space inside the storage ring had become extremely tight, and there was no room for anything other than a few books and a few small items.

After taking the book, Jiwen swept through the relevant pages, but he still had no clue. In desperation, he thought about what Master Niels had just said.

"The crystal disk is a mage made of rock and metal, and it reflects the origin of magic. ”

The origin of spells, Givens suddenly picked up the book "Origin of Spells" written by Evans, although there are differences between the two words in the elven language, but there are also many origins between the two words. Maybe there's something in this spell book that inspires you.

Givens began to flip through the book carefully, this time rereading the origin of the spell, carefully searching for the sentences he had skimmed before, trying to find the relationship between the spell casting and the crystal disk. Finally, a note from Evans jumped into his eyes.

"In this world, spells are not derived from spiritual power or meditation, nor are they gifts from the gods, and there is no trace of the legendary magic web. There's just an endless stream of spells. This powerful torrent of spells is filled with magical energy, spreading throughout the world, circulating through and never stopping. And it's the root of all spells!"

Seeing this, Jiwen hurriedly turned a few more pages back until he saw another paragraph.

"The caster only grabs a tiny drop from the torrent of spells by virtue of his physical characteristics, turns it into the energy of his own spell casting, and finally appears in the world in various spell appearances through spell casting and chanting. ”

It suddenly occurred to Given, if the crystal disk was also a spellcaster, then it was just like an ordinary summoner or a magical creature, drawing energy from this torrent of spells, and then converting it into a specific spell output according to the arrangement of the crystals.

If explained in this way, Givin felt that this mysterious crystal disk was not as difficult to understand as before.

But in this system, what role does the user of the crystal disk play?

Givens remembered the illusion he saw when he used the crystal disk, where his spirit drew those torrent-like spell energy and controlled the crystal disk to run.

Could it be that those hedron warriors are acting as controllers and guides of the crystal disk, so that this spell can be cast in an orderly manner? If that's the case, why do you suddenly fail at the last step of casting a spell every time?

If the cold can appear, then it means that the location of the spar is fine, and the resonance between himself and the spirit disk is also smooth, and the control of spell energy has not failed. All the problems focused on the moment when the Ice Arrow was about to appear, and instead of transforming into cold and frost gushing out, the energy destroyed the machine labyrinth in the illusion and dissipated.

Jiwen remembered that in the spell-casting fantasy, the machine labyrinth could not hold the power of the torrent of spells. That shows whether the crystal disk has some structural weaknesses.

Like what...... The torrent of spells that he was channeled into the crystal disk was too powerful, beyond the limits of the crystal disk?

If this is the case, then it is necessary to adjust the carrying capacity of the crystal disk.

Givens closed the spell book and re-examined the notes. The notes only sporadically mentioned that if you change the thickness and texture of the crystal disk base while maintaining the spatial configuration of the gem, you can slightly adjust the power of the spell even if you don't change the crystal.

After seeing this record, Gilvin decided to squeeze the pedestal and give it a try.

Fortunately, it's a metalworking job. Thankful for his luck, Givens quickly began to pick up the tools, then softened the base with the furnace, and then changed the shape and thickness of the metal base of the crystal disk.

During the tinkering process, Givens paused from time to time to cast spells to check the consequences of the disc modifications. Jiwen slowly noticed that as the adjustment continued, the torrent of spells entering the crystal disk became more and more stable, and no longer leaked out.

Soon, Given's only one last step remained: fine-tune the crystal disc and let it cast spells.
