Chapter 207: Magical Vision

After spending a little over a week, Murphy completed the modeling of the wand core antenna array and also quickly produced a model of the wand shaft—assigning this task to the two little ones was only to let them become familiar with using mathematical tools; he didn't really expect them to produce a very good model.

But the wand core antenna array model already has hundreds of parameters, and if refined it could reach tens of thousands; optimizing the model requires a massive amount of tedious, repetitive calculations.

He needs a large computer.

And a computer cannot operate in Hogwarts's magic‑rich environment, so Murphy returned to the Magic Research Institute.

"The Research Institute's super‑computing project isn't finished yet, but as far as I know, Umbrella Corporation currently has over 40,000 network‑connected computers, with more than half of the Computational Power idle; we can use them for the calculations first."

The head of the Magic Research Institute's super‑computing center, Bu Li Sai Mei Sen, said.

"Distributed computing?"

"Yes."

"That works," Murphy thought, "Find a few people who understand genetic algorithms; this model is better suited for iterative genetic algorithm optimization. Contact me as soon as you have results."

"Okay, but how should we deliver the results to you?"

Murphy was about to say that the two ravens stayed at the Research Institute, but then realized that for a task of this complexity, he would inevitably need ongoing communication with the Institute.

He can indeed receive signals through the two ravens' senses, but the Institute can only get his feedback via the ravens' relayed messages; simple commands work this way, yet asking a raven to convey formulas or technical terms would be asking too much of the bird.

However, Hogwarts has no telephone…

Murphy thought for a moment and took out a Goblin Gold Coin.

This thing can transmit sound, but it has a range limit—generally one or two hundred meters is the maximum.

Communication between the ravens and him has no distance limit, but the transmitted content is rather limited.

Could the two be combined?

If we treat the Goblin Gold Coin as an intercom, the ravens become ultra‑long‑range satellite links, perhaps even quantum communication; maybe the Goblin Gold Coin's signal could be relayed through the ravens?

That shouldn't be difficult.

He summoned a raven, placed the coin beside it, and directed his own Magic Power through the raven to flow into the coin.

Then he took out a second coin, tapped it, and the coin next to the raven instantly emitted the knocking sound.

Effective!

In this setup, Murphy and the raven act as two signal towers, the two coins linking the raven and Murphy, connecting them through the channel between them.

The precise mechanism of the coin can be studied later, but for now, it already works.

Murphy handed the coin to Bu Li Sai Mei Sen, "Use this to call me."

By the way, seeing images through the raven and conversing via the coin—does that count as a magical visual telephone?

Although it's one‑way visual.

…

Before returning to school, Murphy asked Goblin Locke for the method of making Goblin Gold Coins.

In forging, Goblin Gold Coins are the same as ordinary Galleons; they only differ slightly in shape for easy distinction.

The reason it can handle long‑distance calls is a ritual called "Greedy Whisper."

It can link several or even hundreds of coins, allowing them to transmit surrounding vibrations and sounds between each other; thus, even if a coin is stolen, the thief's movements can be heard, and when the coins are stacked together, any disturbance triggers a feedback of overlapping sounds that emit a sharp, terrifying howl, forming an alarm.

This is an ancient magical ritual the Goblins devised to prevent their treasure from being stolen.

The ritual is somewhat complex: first soak the coins to be processed in a Magic Potion called "Thief's Blood," then stack them in a Goblin formation composed of several nested concentric circles and two quadrilaterals, recite a long incantation, and finally let it sit for half a day; the coins will then become Goblin Gold Coins.

Fortunately, preparing the "Thief's Blood" Magic Potion is relatively simple and cheap; the biggest difficulty in making Goblin Gold Coins is that the ritual only works with gold, so non‑rich people can't afford it.

But luckily, Murphy is currently the biggest wizard billionaire in the United Kingdom.

…

On the last Friday of October, Murphy shared the Goblin Gold Coin forging method with all the practical‑class students and rewarded the three best‑performing groups over the past two months with a number of coins equal to each group's size.

"You can use these Galleons to forge Goblin Gold Coins, making it easier for your group members to communicate within the school grounds."

Murphy's plan to connect all the house common rooms isn't feasible yet, so this serves as an alternative.

The three groups—Hero Team, Qiu Zhang's group, and Di An's group—were all thrilled; this gadget can handle real‑time calls over great distances, and even aside from its practicality, it's just awesome!

Imagine pulling out a Goblin Gold Coin in front of a crowd and saying, "Hey, are we having dinner at the Ravenclaw table or the Gryffindor table?"

When the crowd looked in surprise, they'd see it was a Goblin Gold Coin!

There are only a few of these rare magical items in the whole school!

The cool factor instantly spikes, right?

Then, basking in everyone's envious, jealous, hateful gazes, say, "Sigh, a busted coin—signal drops after just a few hundred meters."

As extravagant as Versailles.

"Professor, I heard you have a method to measure Magic Power values, is that true?" During a break, Di An's group approached him, "May we borrow it? The broomstick's branches seem to require extremely precise Magic Power, and we can't figure out the trick."

Several other groups have the same request.

Qiu Zhang's group: "Professor, we want to know how to control the distribution of Magic Power during transformation."

Hero Team: "If we use your Magic Power testing device, perhaps we can detect whether the Ghosts actually have Magic Power."

Even Malfoy's group showed up: "The Magic Power concentration in pure‑blood descendants' blood should be higher than that of mud, cough, Muggle‑born wizards; using that device might prove it…"

Murphy was very pleased; after two months of training, they at least had adopted the mindset of "verifying ideas through practice."

He generously gave each group ten Magic Power Detectors to support their projects.

This also served as a wake‑up call for Murphy.

Methods of observing Magic Power are undoubtedly crucial to any magical research; many spells are elusive perhaps because wizards lack a way to directly observe Magic Power.

If a wizard could directly "see" Magic Power, it would surely be easier to guide it to produce specific changes or effects.

This is also a way to "enhance a wizard's cognitive ability" within the Spellcasting Path.

Although the Magic Power Detector is precise, it is still not intuitive enough.

Is there any method that would let wizards observe different attributes of Magic Power directly, as easily as seeing various colors?

The principle of the Magic Power Detector is the Magic Power luminescence effect of gemstones... then, gemstone glasses?

That probably wouldn't work too well; ambient Magic Power radiation isn't enough to significantly alter a gemstone's color, otherwise there'd be no need for a Magic Power Test Device.

If approaching it from the visual angle... add several types of cone cells?

But research on Magical Creatures is still far too scarce at present, with no animals possessing similar abilities discovered to use as reference, and even if such creatures existed, before solving the controllability problem of multiple Animagus Transformations, he probably wouldn't be able to simply and crudely graft this ability over.

Or perhaps, a Magic antenna?

The flow and Transformation Dimension of Magic Power both radiate Magic signals, and these signals can be received by Magic antennas such as wands; if one built an ultra-high-resolution ultra-short-wave receiving array, it might be able to receive high-frequency Magic signals just as visual cells receive light signals.

Then by using different gemstones to distinguish the nature of Magic Power, that would be equivalent to having 6-color Magic colors, which in theory could produce a very good image.

It's just... those Magic antennas serving as Magic Power visual cells, to achieve resolution similar to the human eye, would need to be shrunk to the micrometer scale; at such a small scale, one might need Chip fabrication technology to make them.

However, since the wand design needs to wait for calculation results anyway, let's research this first.

It happens to fit together with the topic of "how to use fusion potions to guide wand cores into generating specific forms."
