After reaching the agreement, Master Niels kept his word, and he took out various books and illustrated books that could only be exchanged within the guild, and even told Gilvin the skills and tricks he had developed on his own.

Given's frenzied absorption of this knowledge was frantically soaked, as he had carefully studied Master Niels's notes before, and had a lot of practical experience, and he quickly mastered the method of making crystal disks. Especially after reading through those documents, Givens finally discovered a few essentials of crystal disc making.

The crystal disc making technology has gone through a long period of development, and the configuration of the crystal disc has long been fixed, and all the makers have to do is to make subtle adjustments according to the characteristics of the user.

According to the current mainstream theory, the spirit pattern is the channel through which the torrent of spells enters the crystal disk, and the higher the degree of compatibility between these channels and the user, the more likely it is to achieve magic. Therefore, the elves designed the transparent crystal sink, trying to find out the characteristics of the user's channeling of magical energy, and then design the direction of the spirit pattern according to the shape of the energy flow in the sink.

In addition to the spirit pattern, there are also detailed regulations for the spars used in the crystal disc structure, which must not only meet the requirements of the crystal disc design, but also be able to fit the user. Each maker has a thick gemstone manual to guide the selection of stones.

The last thing to pay attention to is the choice of materials for the base of the crystal disc and the spirit pattern. Different spells require different materials. For example, the Ice Arrow Crystal Disk that Jiwen used to use must use the rare mineral Cold Iron from the north on the Spirit Pattern.

Although these principles are somewhat in conflict with Given's own experience, they finally let Given's previous attempts continue to fail. Because he hardly got it right when it came to the choice of materials and gemstones.

After watching Given's rough translation of these materials, Master Niels asked, "Mr. Copperbeard, what is your own experience?"

Hearing this, Givens closed the book, looked at the inquisitive Master Niels, and replied solemnly: "There may be many fallacies in my understanding, and you may hear many concepts that are difficult to understand, but I can assure you that what I say is an expression of the real thoughts in my mind. ”

He knew that what he was saying might be too deviant for the elves, and he had to explain it first to avoid Master Niels thinking he was making up a few lies.

After seeing Master Niels nodding earnestly, Given's bold idea that he had been thinking about these days.

"Master Niels, you already know that there is a special structure in the crystal disk that I modified. Although I inadvertently changed it to this shape, I can already confirm that this represents an interesting discovery after seeing that you repeated the configuration as well. ”

Master Niels raised his head, a strange glint in his eyes, and waited for Givan to continue.

"In my opinion, the torrent of spells that has been mentioned by countless people is just an energy that spreads in some way, and the function of the crystal disk is to receive this energy and then change and process it before emitting it in spells. The changes I made were just to make the crystal disk receive the energy from the torrent of spells more efficiently according to some special rules. I prefer to call this structure an antenna, and each crystal disc should be able to be improved by modifying the antenna. ”

"Energy, antenna?" Master Niels muttered as he repeated the words that Givan had just coined, and it seemed too difficult for him to understand Giving's words. Fortunately, there is only this paragraph for such a difficult sentence, and the rest of the part, even Geevin himself needs to verify in the future.

"Then why is this antenna the way it is? Is there some mystery in it? ”

"Yes, the characteristics of the spell torrent determine that some special shapes can receive energy more efficiently, but whether there is only this one shape, I am not sure, it will take countless attempts. At the moment, I've only figured it out so far. ”

After saying solemnly, Givens waited for Master Niels to respond. Does he think it's all nonsense?

But Master Niels's reaction made Given's worries superfluous.

"It's incredible. “

Master Niels was still unsatisfied, although what Givin said was jerky and difficult for him to understand, and although what Givan said almost subverted his cognition, he knew that what he had learned could not explain the strange structure, so he was willing to choose to believe this Mr. Copperbeard.

Givens made no reservations about Niels, for he was anxious to see if all the things he knew about Earth technology that were used in the electromagnetic realm could be applied to this wizarding world ruled by elves. In particular, whether this fishbone structure similar to the Yagi antenna is just a bizarre coincidence.

And all this work is inseparable from the help of Master Niels, at least for now.

So, Givens spoke again.

"Master Niels, if I want to figure this conjecture, I will probably have to do many more tests. You know, I'm not skilled in making crystal discs, and I need a skilled collaborator. “

Master Niels smiled, he understood what Givin meant, and the Copperbeard was inviting him to participate in the whole process of researching this.

"I'm honored to do it, Mr. Copperbeard, and from today onwards, please make the Flame Forge your research room. ”

"But my experiments can mean a lot of waste, and you said that cold iron is an extremely expensive material. Seeing Master Niels so generous, Gawain was embarrassed to express his concerns, after all, not every elf does not have to think about the cost like Gilvin.

But Master Niels shook his head unconcernedly.

"Don't worry about this, that's a headache for me. Okay, now it's time for me to make another promise. Come, I'll help you make a new crystal disk. ”

In this way, Givens and Master Niels became good partners. They immediately discussed the design of Gevon's new crystal disk in detail, after which Geewen took his leave and left. Before leaving the Furnace, Givan borrowed a few books from Master Niels, copied down a number of notes, and stuffed them into his storage ring.

Just as Given's office was leaving, Master Niels specially reminded: "To make a crystal disc that casts ice arrows, you must use cold iron, and buying cold iron in the guild requires strict registration and grade usage, and I can only wait for a black market merchant to supply it, so your crystal disk will have to wait two more days." ”

"It's okay, I don't care about these days. ”

Ji Wen is not in a hurry to use the crystal disk for the time being, so he doesn't care about this delay, what he cares more about is that he must have paid a lot of price for buying the black market Cold Iron Niels Master this time, and Ji Wen plans to find something to compensate Master Niels after returning to the Forbidden God Space.

When leaving the flame furnace, Master Niels had been sending Givin and Adelia for two blocks before returning, seeing Master Niels's expression, Adelia couldn't help but ask curiously, "Do you really know how to strike iron? Even Master Niels has to ask you for advice?"

"Of course. Givens said a little smugly.

"You didn't fool Master Niels?" Adelia was still a little unconvinced, though some summoners would use low-level summons as livestock or summons as mounts. But she had rarely heard of a summoned beast that could do such a complex job as striking iron. Especially since this bizarre thing happened to her own summoned beast.

"Of course not. Givens shook his head.

"But at first, I didn't think you had that talent at all?"

Adelia was a little puzzled, she had glimpsed it in Jiwen's memory when she signed the blood contract, and she had never seen a scene like striking iron at that time. But if Given's not lying now, when and how did he learn such a craft?

Looking at Adella's thoughtful expression, Givens felt that he had to quickly divert the topic. Just after communicating with Master Niels, he had a question that he wanted to ask Adelia to teach Adelia to cast ice magic, so he blurted out, "By the way, Adelia, I want to ask, how do you feel when you use ice magic?"

"Feelings?" said Given's sudden question, which surprised Adelia a little.

"Yes, that's how you let that magic eventually turn into magic. Given's desperate description, trying to make Adelia understand what she was thinking. He wondered how much of a difference the magic cast through the caster was from the magic cast on the crystal disk.

Adella didn't quite understand what Givens meant, but she felt it was too risky to talk openly about her unleashing ice magic on the streets, so she pointed to an alley and said to Given, "There are too many people on the streets, let's go somewhere else." “

Adelia remembered that down the alley, there was a small mound covered with dense forest, which was a good place to discuss secrets.

Soon, Adelia and Givens were on the hill covered by the trees, and it was already dark because Gilvan had been in the furnace of flames for so long, and the woods were almost out of sight.

Fortunately, with the characteristics of the silver dragon bloodline, Givens and Adelia were able to walk on this forest path without fear of darkness. But when Jiwen opened his mouth to ask how he felt about casting spells.

Adelia suddenly stopped alertly, put her finger to her lips, and motioned for Gilvin to be quiet.

She noticed something unusual in the woods, as what appeared to be a fight came from the air ahead.
