Lord: Starting with Summoning the Regular Army of Earth

This is just Matthew's initial idea. To determine its feasibility, we need to consult with the experts in the technology group to learn more about the specific casting process, or inform them about the abilities of the Mage's Hand, and discuss the feasibility together.

But aside from its role in the casting process, Matthew felt that the Wizard's Hand could definitely be useful in precision machining.

For example, a mage could use their skillful hands to delve directly into the still very rough interior of the initially cast cylinder, like the finest sandpaper and grinding head, to polish and shape it at a "microscopic level" from the inner wall.

According to Professor Zhang Hongjian, traditional boring machines require a sturdy bed, precise guideways, and tool post to achieve precision machining.

But the "Hand of the Mage" itself is an all-purpose tool that ignores physical form, obeys the will of the mind, and can even achieve atomic-level precision.

It is not afraid of the high temperature inside the cylinder, it can adapt to any curved pipe, and its power and movement trajectory can be precisely controlled by mental power.

This means that there is a shortcut to achieve the required precision by bypassing traditional machining.

Thinking of this, Matthew's heart pounded, and he was incredibly excited.

Because if everything really goes as planned, it will greatly shorten the time it takes for Ember Ridge to enter industrialization.

However, Matthew also knew that this was still a bold, nascent idea, and its implementation would inevitably be fraught with challenges.

For example, the mental exertion, the perception of the internal shape of the cylinder, the grinding efficiency, etc., are all unknown and may require exploration and trial and error.

But in any case, it at least gave Matthew a glimpse of a hopeful direction.

Once magic is integrated with industry, many precision machining experiences and high-risk processes that require long-term accumulation can be replaced or simplified by magical means, enabling a leapfrog development.

Matthew took a deep breath, suppressed his excitement, and focused his attention again. He began to carefully study the spell model of the Wizard's Hand, trying to understand every subtle magical structure and every magical flow path.

The initial excitement was quickly overshadowed by the complexities of reality. This spell truly lived up to its reputation as the most difficult zero-ring spell; the complexity of its model far exceeded his expectations.

Unlike the Micro-Light Technique, which is a relatively flat energy gathering structure, it is an extremely complex, nested, three-dimensional energy architecture, resembling a miniature precision machine, requiring an extremely high degree of precision in controlling mental power.

After a long while, Matthew began his first attempt. He closed his eyes, mobilized his mental energy, and began to construct the first energy node, guiding the flow of magic.

However, after only one-tenth of the model was built, the entire model collapsed instantly due to an energy overload in a tiny loop, causing him to feel dizzy from the backlash of mental energy.

"Hiss... such a complicated structure." Matthew rubbed his temples, realizing that the difficulty was far greater than expected.

The next few attempts yielded the same result.

He found it difficult to maintain the stability of the entire three-dimensional structure in his mind at the same time.

Often, focusing on one aspect leads to neglecting another; when attention is paid to the upper-level structure, the underlying basic circuitry begins to become distorted.

The core energy flow was stabilized, but the peripheral auxiliary nodes were shut down due to insufficient energy supply.

This model is like an extremely fragile three-dimensional maze woven from light threads, which could collapse completely at the slightest carelessness.

"Sigh, this spell is really difficult. It feels like playing three games of 3D Go in my head at the same time!" Matthew looked at the book lying between his legs, somewhat troubled.

But he would not give up easily, after all, this was a spell that would lead to a technological leap, so he had to conquer it no matter what.

After calming himself down, Matthew continued his attempts, only to fail again and again.

In the end, he was completely numb. He had thought he was a magical genius, but the magician's hand had brought him back to reality.

He collapsed onto the bed in despair, suddenly remembering the girl with long, straight black hair. He subconsciously touched the magic pendant, wondering if the spirit of the pendant could come out and help him again.

"Night Song, Miss Night Song, are you there?" Matthew called out in his mind, but received no response.

It seems that I am unable to communicate with the spirit of the artifact directly with my thoughts like the protagonist in the novel, and I can't even sense her presence at all.

So Matthew raised the magic pendant and called out to it, "Miss Nightsong, Miss Nightsong, can you hear me?"

However, all that answered him was the sound of the candle burning and the chirping of insects outside the window.

"Looks like that won't work either!" Matthew was a little discouraged. He recalled that night when he was awakened by a book hitting him after he fell asleep, and then he saw Miss Night Song appear.

Of course, he wouldn't be so foolish as to think that throwing books at himself is the way to summon the long-haired black-haired lady.

Does she mean she'll only appear after I fall asleep?

Matthew thought to himself.

But what he didn't know was that "Miss Night Song" was indeed in his room at that moment, and had heard his call.

Seeing Matthew holding up the crystal pendant and calling her name, she couldn't help but smugly mutter to herself, "Foolish human!"

Night Song had no intention of helping Matthew anymore. She helped him last night because she didn't want him to go astray, but helping him now would only harm him.

She despised those good-for-nothings who had no ability of their own and had to rely on others for everything.

If this guy can't even understand a zero-ring spell, then he's just a hopeless case and not worth my continued help.

However, Night Song also knew that the Mage's Hand was indeed very difficult. For someone like Matthew who had just come into contact with magic, even if he had great talent, it would probably take him three to five days to learn it. This was a challenge that every mage had to go through.

"Forget it, I can't rely on others for help every time I encounter a problem. I can't let that spirit look down on me." Matthew's fighting spirit was rekindled.

He carefully considered the spell model again, repeatedly visualizing and simulating it in his mind, over and over again.

After an unknown amount of time, the experience of being tormented by solid geometry suddenly flashed through my mind like lightning.

"Three-dimensional...solid structure...coordinate system!"

A thought struck like a thunderclap.

Why must you simultaneously visualize the entire complex, abstract three-dimensional model?

Why not break it down into smaller dimensions?

He recalled the spatial rectangular coordinate system (X-axis, Y-axis, Z-axis) commonly used in math class.

Any point in three-dimensional space can be precisely located using (x, y, z) coordinates.

"Perhaps I can construct a magical three-dimensional coordinate system," Matthew thought to himself.

He decided to use a completely new method to "understand" and "construct" this spell model.

The first step was to establish a frame of reference. He first created a virtual three-dimensional coordinate system in his mind, centered on the magic pool.

Then, try to understand and memorize each key energy node in the spell model using coordinates.

For example, the core energy source is at (0, 0, 0);

The first branch node is at (1, 0, 2);

A key structural support point is located at (-1, 3, 1)...

Then, path decomposition is performed, breaking down the complex three-dimensional energy loop into two-dimensional projections on the XY plane, YZ plane, and XZ plane to construct them separately.

Finally, the construction is carried out in layers. Imagine the entire model as a building. First, lay a solid "foundation" and then "build" it up layer by layer. After ensuring the stability of each layer, build the "energy elevator" that connects the layers.

This method breaks down the difficult task of constructing a complex 3D model into a series of relatively simple 2D planar construction and precise spatial positioning problems.
