42: Urban construction equipment research and development

In the following days, Brian re-adjusted his thinking and shifted his research focus to the Level 4 city builder.

After all, the complexity of a Level 4 Magic Formation far exceeded that of a Level 3, and just the spatial storage and flight functions required deep optimization of the Magic Formation structure.

He started with basic Magic Formations, categorizing the information Spirit Eye had compiled by difficulty, beginning with the simplest levitation Magic Formation.

Brian found that flight capability was relatively simple, and there were already related flight Magic Formations.

However, the entire machine body ideally needed to remain lightweight.

He needed a material that could withstand high-intensity magic while remaining lightweight.

He then began searching the magic net for more rare magical materials.

"obsidian won't work, it's too brittle; mithril is too soft; perhaps an alloy of wind crystal stone and starfall iron..." Brian jotted down material combinations in his notebook, noting the characteristics of each material.

For the next few days, Brian practically lived in the laboratory.

He constantly adjusted the Magic Formation structure and tested the effects of different material combinations.

Whenever he encountered a bottleneck, he would return to basic theory and re-derive the formulas.

"creator, you have been working for 36 consecutive hours; do you need to rest?" Spirit Eye's voice carried a hint of concern.

"Just a little longer, I'm close to finding the key point." Brian didn't even lift his head, his eyes fixed on the Magic Formation model in front of him.

Finally, on the morning of Brian's fourth day of obsessive work, Brian successfully constructed a stable prototype of a Level 4 Magic Formation.

He placed a sample of the wind crystal stone and starfall iron alloy into the center of the Magic Formation; magic power slowly flowed, and the alloy gradually floated and deformed, eventually forming a solid magical material.

"Success!" Brian excitedly pumped his fist.

"Spirit Eye, help me calculate the production and cost of this alloy," Brian said into the air.

"creator, according to calculations, each unit of alloy requires 3 grams of wind crystal stone and 5 grams of starfall iron, costing approximately 11 intermediate magic stones," Spirit Eye responded quickly.

Brian nodded; this cost was within his acceptable range.

He then began to refine the overall design of the city builder.

First, he listed the city builder's objectives.

The city builder was created for rapid city construction and for quickly building military fortresses in subsequent planar wars.

Therefore, it should possess the ability for large-scale spellcasting and defensive capabilities.

Large-scale construction of city walls, large-scale construction of houses, large-scale construction of roads, etc.

In that case, if using a 'freebie' combined Magic Formation, houses and roads would be fine, but for city walls, digging dozens of meters deep probably wouldn't be enough.

This would require setting up multiple sub-units that can fly and collect materials from other places.

This sub-unit needs to have spatial storage and spatial teleportation functions; after collecting materials to a certain extent, it can directly teleport the materials into the main body's storage space.

The sub-unit also needs to have certain auxiliary construction functions.

Next was the issue of building sturdiness.

Creations from the 'freebie' combined Magic Formation could only reach Level 1.

Other materials must be added and smelted to improve them.

obsidian and fire copper are famously sturdy and relatively cheap.

However, these two combined and smelted can only reach Level 3, so it seems a high-grade material needs to be found.

However, other materials might not be necessary, as Level 4 Mages all fly in legendary Mage Towers when they go on expeditions.

Normally, these are only used by knights or servant armies.

If all else fails, a Magic Formation can still be set up on the existing foundation!

However, for some higher demands, a high-grade material capable of fusing materials to a Level 4 standard is still needed.

It would be sufficient to set up templates for Level 3 hardness and Level 4 hardness separately; they can use them as the situation demands.

Then the main body of the machine would need multiple spatial storage Magic Formations, with the material storage area partitioned for various materials.

As for defensive capabilities, engraving several combined Level 4 defensive Magic Formations should suffice.

The energy core would require at least 10 Level 4 energy cores for power supply.

Various adjustable building templates also need to be set up.

Brian sketched the three-dimensional structural diagram of the city builder on paper while mentally calculating the connection points of each Magic Formation.

He thought that the spatial storage Magic Formation of the sub-units should adopt a nested design, allowing more materials to be stored in a limited space.

Moreover, the spatial teleportation Magic Formation must be precisely positioned to avoid material teleportation errors, which could otherwise affect the entire city construction progress.

For large-scale spellcasting capability, Brian decided to use a combination of multiple small spellcasting Magic Formations, which would ensure the spellcasting range while allowing flexible adjustment of spell intensity and direction.

In terms of defensive capabilities, he planned to superimpose several Level 4 defensive Magic Formations of different attributes to form a powerful magical shield capable of resisting various types of attacks.

At the same time, he was also considering how to optimize energy utilization efficiency, allowing the city builder to complete more construction tasks with less energy consumption.

For adjustable building templates, Brian planned to design an intelligent system that could automatically adjust building styles and structures according to different needs.

For example, when building a military fortress, it could quickly generate defensive city walls and strongholds;

When building a city, it could generate houses and public facilities of various styles.

As for the Level 4 construction material formula, after experiments by Brian and Spirit Eye, suitable materials were finally found among many options.

One was blue fire copper, considered a superior material to fire copper, characterized by its relatively cheaper price among various materials. When fused with obsidian and fire copper, the building strength could reach Level 4.

Another was crystal jade, a very beautiful material. After fusion, the material's surface presented a jade-like texture, making it an excellent material for building luxurious villas and castles. After fusion, it could also reach Level 4 strength, but its price was about twice that of blue fire copper.

Both of these could be added to the templates.

Afterward, Brian began to draw detailed blueprints for the city builder, marking the Magic Formation type and material requirements for each component.

"Next, it's time for actual manufacturing." Brian looked at the blueprints, his eyes gleaming with anticipation.

Brian first set up a small manufacturing platform in the laboratory, arranging all necessary magical materials and tools one by one.

Following the detailed annotations on the blueprints, he started by manufacturing the sub-units.

When constructing the spatial storage Magic Formation, he precisely nested each small Magic Formation, ensuring they operated stably and without interference.

For the spatial teleportation Magic Formation, he repeatedly adjusted the positioning parameters and conducted extensive simulated teleportation tests until materials could be accurately teleported to the designated location.

Subsequently, he began assembling the main body of the city builder.

When installing multiple spatial storage Magic Formations, he carefully planned the storage area for each Magic Formation, ensuring different materials were stored in separate sections.

When engraving the Level 4 defensive Magic Formation, he meticulously drew each rune line, ensuring every stroke was precise and accurate.

When installing the energy core, he carefully checked the connection lines of each core, ensuring that the 10 Level 4 energy cores could provide stable energy for the city builder.

When developing the intelligent system for the adjustable building templates, Brian directly had Spirit Eye write the complex magical program, as Spirit Eye was best at this!

He then continuously tested the system's response speed and accuracy to different building requirements.
