Melita left, taking the ring left by the cultist with her as she left, and as a bargain, and as a thank you to Gawain for helping to recover the ring, Melita made a promise on behalf of the Mithril Treasury:

In the future, whenever there are any fragments of eternal stone tablets that have been left behind, or "inhuman strange objects" similar to them, they will be given priority to telling Gawain.

For Gawain, the value of this promise is far more valuable than the ring.

But a disgraced half-elf didn't seem to think so, and Amber lay on Gawain's desk, pressed her face to the table, and collapsed there like a salted fish, muttering as she slumped, "It's such an expensive thing to look at...... Just took it away...... Not a single copper plate is removed...... The people in the Mithril Treasury are too picky...... And I have to have a meal when I leave......"

Gawain squinted at the guy, "They'll help gather information on the Eternal Stone Tablet and the like, don't you think it's more valuable?" ”

"That can't be spent on money, and the veiled woman is easy to say, God knows how long it will take them to find new shards of slate—that's eternal slate! It's not a stone in the road," Amber continued to paralyze, "Ah, if they can't find it in a hundred years, why don't you wait a hundred years?" ”

Before Gao Wen could say anything, he heard this guy continue to chatter crookedly: "Ah yes, you have special skills, it's a big deal that when you get bored, you will die and pull it down, and then when they find it, let your children and grandchildren go to your grave and burn the news to you, and you will crawl out again......"

"From the bottom of my heart, even if you're the chosen choice of the God of Shadows, it's a miracle that you're alive," Gawain raised an eyebrow and glared at Amber, "stop talking nonsense—go and help me open that box over there and bring the bag on top." ”

Amber got up from the table with a salted fish, and swayed to the thing as she muttered, "Isn't it usually Betty who does it for you, why is it my turn today—where did that little maid go?" I haven't seen her for most of the day......"

"I gave her a half-day off to get acquainted with the place with her peas. Pea is very scared of life and can't speak, and is easily frightened when she comes into contact with people in the territory, but she and Betty are unexpectedly very compatible, and maybe they can be friends. ”

Amber grinned as she placed the bag in front of Gawain, "I'll tell you, I really appreciate you now—I thought you were all about being approachable at first, but now it seems to be true." People who are not serious will not be able to arrange for you to do this. ”

"Thank you for your appreciation." Gawain casually pulled Amber's head aside, then poured out the contents of the bag.

Inside was a pile of dull gray-white crystals, the average size of a little finger, with a bit of a misty color on its surface, with the mysterious aura peculiar to the magic material, but it didn't look like a high-end thing in terms of appearance or texture.

"What is this?" Amber had just been quiet next to her for less than two seconds, and immediately came up again after seeing these things that seemed to be able to be sold for a little money: "Crystal? But looking at the quality of the ......."

"This is the Demon Storage Crystal that has just been shipped from Tanzania, and it can be regarded as a sample of the first shipment. You forgot? I had a huge long-term order for that Viscount Andrew. ”

"Magic Reservoir Crystal? This thing?! Amber stared at the gray-white crystals for a moment, and then suddenly exclaimed, "That Viscount Andrew doesn't bring such a trick!" We saved his life, and he used this thing to fool people? This crystal is left in a slightly larger bonanza, and it is all thrown away as slag, okay! ”

Gawain looked at this puffed out half-elf with a little surprise, he never thought that this guy who didn't care about anything in the territory before would be so angry because of the loss of the territory at this time, but he just smiled: "Don't say it so exaggerated, this thing is much better than the slag, and that Mr. Viscount is not a trick at all - he sold these crystals to us at the price of three Cecil silver coins and one taka (weight unit), where can you find this price?" ”

"Three silver coins......" Amber thought quickly about the size of the newly minted silver Cecil, and then her face became subtle, "That's cheap enough...... But what are you buying so many inferior storage crystals for? This kind of quality ...... I'm afraid that only the most basic mage apprentices will use it when doing exercises, right? And the mage apprentices who have a little money are probably not willing to use it. ”

Gawain smiled: "Do you know what the biggest problem with this inferior magic storage crystal is?" ”

"The ability to store demons is only half of that of high-quality crystals of the same volume, and the energy escape is extremely serious, especially the second one, which directly makes them useless," Amber obviously still understands these common sense issues, after all, it involves whether or not they can be sold for money, "The reason why artificial magic storage crystals are not popular is also due to this reason. ”

"That's right, the low ability to store demons is just a small problem, just put two more crystals, the biggest problem is that the energy escapes quickly, and it won't take long for the magic power to dissipate by itself, which is a fatal wound for crystals that are 'demon storage' in themselves, so these crystals have become so worthless, although they have huge reserves, they are difficult to come in handy," Gawain said as he opened the locker under the table, took out a hexagonal metal plate from it and put it on the table, "But if you think about it differently, These energy-hungry crystals can also come in handy......"

Amber looked curiously at the metal plate that Gawain took out, she recognized that it was something sent by Rebecca not long ago, it seemed to be a product of the machine factory, this metal plate was only a little larger than a palm, hexagonal, it was the kind of "industrial product" that was pressed out in an instant in the machine mold with the latest "stamping and forming technology", and on the surface of the metal plate, you can also see the neat groove pattern, as well as the magic material embedded in the pattern.

It was a "universal substrate" engraved with a circle, and Amber thought she had seen the runic structure on it.

After trying to remember for a long time, she said "oh-" and said: "Oh~~ I know, this is the thing that Rebecca and Jenny drew before!" ”

"The Honeycomb Magic Net Unit, which is a base unit that works on its own, I carved it on a universal substrate that can be moved, and it becomes a 'part' that can be combined with other things at will," Gawain said, flipping the substrate over to reveal the vacant grooves on the back of the substrate, "and these slots are connected to other things." ”

"So this metal plate is gathering mana right now, isn't it?" Amber looked at this new thing in amazement, which was completely different from the traditional magic item painting style, "And what are you going to use all this magic for?" With such a small magic net unit, the magic power that can be gathered should be limited, right? ”

"It's really limited, just with the output of this magic net unit, it's very difficult to even activate a first-level spell, so you have to charge the energy into these crystals first," Gawain pointed to the inferior magic storage crystal next to him, "After completing a charging cycle, the magic power in the crystal will be exported, and since the charging is continuous, the escape of the crystal is no longer a problem." You see, it acts as a scratchpad in this system, which is used to store the small amount of mana generated by the magic net unit, so as long as the crystals form an array, supplemented by a long enough recharge period, then it is completely possible for such a base unit to release enough magic power to drive advanced spells. ”

Amber's eyes widened halfway through hearing it, and when she heard it, the last look in Gawain's eyes was wrong: "You guy...... Are you really sure you're a knight? ”

"Uh...... As for such a big reaction? ”

"You're a knight, where did you get all this bunch of magical theories!" Amber glared, then looked incredulously at the base plate and crystal of the circle in Gawain's hand - these things hadn't been put together yet, and there were still a lot of key runes and control circles, but it was clearly not far from being completed, "This thing...... Is it a magic device? But it still seems like it's just a part......"

"Yes, it's still a part, but it's a very important part, and with it, I've done the most important part of my plans: how to solve the problem of mobile energy without a fixed magic grid for energy," Gawain smiled, "I'm going to call it the Magic Capacitor, what do you think of the name?" ”

"Magic capacitors?" Amber blinked, "What does this thing have to do with electricity?" Are you going to use it to release lightning arrows? ”

"Uh...... Well, I didn't expect that," Gawain thought about it seriously and put it another way, "then I've decided to call it the Magic Capacitor." ”

Amber: "...... And with this!? ”

Seeing Amber's stunned appearance, Gawain felt great pleasure, so he lowered his head happily and found the batch of drafts that he had not finished calculating before, ready to continue calculating several problems in the power and charging efficiency of the Hive Magic Net Unit, but not long after he started working, he suddenly heard a commotion outside.

"I'll go see what's going on!"

Leaving such a sentence, Amber disappeared in front of Gawain: as soon as Gawain wrote, she would definitely be dizzy to read, and at this time she wished to find an excuse to run away.

But she didn't run out long before she came back in a rage: "Gawain! Gawain! The Byron Knight is back! ”

"He's back?" Gawain immediately put down the pen in his hand, "Let him in!" ”

The knight Byron walked into the tent, and the exploration of the ruins for several days in a row made him look quite tired and dusty, but the expression on the face of this knight gentleman was obviously very excited, and as soon as he entered, he gave Gawain a knightly salute, and then said in an excited tone: "My lord! We have discovered a hidden area in the ruins, which may have been the secret testing ground of the Gondor Empire! There are not only a lot of good equipment, equipment, and materials inside, but also ...... A small number of still recognizable manuscripts and documents were found! ”
