The Brain Martial Soul's Inclination

Whether making Mechas or Battle Armor, Rare Metals were required as materials. Raw, unprocessed metals could not meet the demands of Mechas and Battle Armor.

However, lower-level Yellow-Rank Mechas did not require especially advanced forging techniques. They did not even need Thousand Refined Metal; Hundred Refined Metal was enough.

But even the lowest One-Word Dou Armor required Rare Metals of at least the Thousand Refined level. Moreover, only Thousand Refined First Grade metal could withstand the operation of a Battle Armor's powerful Core Array.

During forging, Forging Masters also needed to hammer the metal into the appropriate shapes.

Mecha Manufacturers had this step as well. While manufacturing a Mecha, they also needed to deeply process every component. However, when it came to shaping the basic form, they still needed a Forging Master's cooperation.

Of course, Xu Yuan's Mecha Manufacturer rank was still low, and the metal he needed was only at the Hundred Refined level. This kind of metal was still relatively easy to forge into shape.

Once one reached Thousand Refined First Grade, Spirit Forging, or Soul Forging, the metal itself possessed spirituality. Mecha Manufacturers who did not understand forging would not casually alter its shape themselves and could only ask a Forging Master to do so.

Under normal circumstances, such a situation would not arise at that level.

For normal high-level Mechas or Battle Armor, the proper manufacturing process had always been for a Mecha Designer to provide the design concept and plan. After designing the Core Array, they had to standardize everything, even the shape and dimensions of every component. Only then came the Forging Master's stage. Once the metal had been forged, the Mecha Manufacturer would inscribe the Core Array onto the prepared metal.

He took out a fist-sized piece of metal from the Assessment Platform.

"This is a manufacturing blueprint for one component of a Yellow-Rank Mecha's Hand Armor. You must successfully make it within half an hour."

Starting at Second Grade, Mecha Manufacturers had to begin actual practical work. They needed to inscribe arrays onto Rare Metals and truly participate in Mecha manufacturing.

Of course, Second Grade Mecha Manufacturers merely played a supporting role. They were only responsible for manufacturing individual, very small parts of a Mecha, such as parts of the Mecha's Hand Armor.

A huge Mecha—even its Hand Armor—was larger than half the body of Xu Yuan, a seven-year-old child. The metal in his hand was clearly not enough to forge an entire Hand Armor; it was merely one part of it.

Xu Yuan swept his gaze over the blueprint and immediately understood.

This was the palm section of the Hand Armor.

It counted as one of the most complicated sections, the core coordinating the arrays in the different parts of the Hand Armor.

But there was no real problem!

Xu Yuan focused, and the Heaven Origin Spear appeared in his hand.

At this moment, the Heaven Origin Spear was not in the form of a long spear. Instead, it transformed into a palm-length "needle," with Five Elements Power gathered at its tip.

The Heaven Origin Spear passed across the metal's surface, effortlessly leaving a scratch on the Hundred Refined Metal. Xu Yuan's Soul Power flowed into it along the scratch.

Xu Yuan's hand was steady.

He was also extremely focused at that moment.

As the spear tip touched the metal, Soul Power also had to be injected into the metal through its point.

This was only the manufacture of an ordinary Yellow-Rank Mecha. If he were making Battle Armor, then even if it were merely One-Word Dou Armor, the Thousand Refined First Grade metal used would already possess rudimentary spirituality. While inscribing the array, he would also need to communicate with the metal's spirituality as much as possible, allowing the Core Array to perfectly merge with that spirituality.

This process could complement the communication with spirituality during a Forging Master's forging process.

So Xu Yuan had not been wrong about one thing: different Sub-Professions could also promote one another.

Of course, all of this could only be accomplished with sufficient learning ability as a foundation.

And Xu Yuan was confident that he possessed such learning ability.

Once his Spiritual Power surpassed five hundred points and reached the Spirit Sea Realm, he could absorb a second Purple Soul Spirit. At that time, he would add a Soul Ring to his Brain Martial Soul, further strengthening his advantage in Spiritual Power.

At present, breaking through five hundred points of Spiritual Power did not seem too far away.

The spear tip traced line after line across the surface of the Hundred Refined Metal. These marks were merely the outermost array patterns.

They were not difficult.

As long as one memorized the array, mastered the various techniques of inscribing it, and steadily completed the entire array in one go, it counted as success.

And all of this was far too simple for Xu Yuan.

The truly difficult part was becoming a Third Grade Mecha Manufacturer. It was no longer merely a matter of copying arrays; one also had to make temporary adjustments on one's own, allowing the Core Array to better suit each piece of Rare Metal. This was where the theories behind Core Arrays began to be applied.

Therefore, mechanical learning could quickly produce a Second Grade Mecha Manufacturer, but reaching Third Grade required fully digesting every array before one could use them with ease.

Xu Yuan would also encounter this process while studying Mecha Design. The same was true for Mecha Maintenance and the study of Core Arrays.

Third Grade was not difficult either.

After all, it was only a matter of learning and digesting.

What was truly difficult was always the technical side, as well as the parts that required comprehension and perception.

Among Mecha Manufacturers, Fourth Grade was the first threshold that truly tested technique.

For Third Grade and lower Mecha manufacturing, Core Arrays were only inscribed onto the metal's surface. But at Fourth Grade, one had to inscribe arrays inside the metal.

This was not a domain that an engraving knife could physically reach. One needed to use the engraving knife to inject Soul Power into the metal and inscribe the corresponding array within it.

As for Fifth Grade Mecha Manufacturing, it built upon Fourth Grade by guiding spirituality, leading the spirituality within the metal to participate in tracing the array.

(In the original work, aside from forging, the ranks and abilities of everyone's other Sub-Professions were a complete mess. For example, Ye Xinglan was Fourth Grade at one point and Fifth Grade at another, and the specific requirements for the various Sub-Profession grades were never described. I can only sort them out as best I can, then create additional settings to flesh out the different professions.)

(Likewise, the original work contains many self-contradictory settings. I will sort those out as well.)

He had been given half an hour, but Xu Yuan completed the manufacturing in only ten minutes.

The moment the arrays linked together and emitted a faint azure glow, it meant that his work was complete.

Cai Yue'er narrowed her eyes slightly, and a flash of surprise passed through their depths.

It had to be said that in just one year, without delaying his Soul Power cultivation or Soul Skill development, Xu Yuan had still managed to raise two major Sub-Professions to Second Grade. This already proved his learning ability.

The reason his uncle Xu Shengqun had not tried to dissuade Xu Yuan over the past year was precisely because of this.

Xu Shengqun had also witnessed Xu Yuan's terrifying learning ability.

Even Mu Ye was the same.

The two had discussed Xu Yuan's situation, and Mu Ye ultimately concluded that this was a characteristic of Xu Yuan's Brain Martial Soul.

There had been Brain Martial Soul possessors in the Body Sect's history, but Martial Souls themselves also had different inclinations. Xu Yuan's Brain Martial Soul clearly enhanced his ability to learn and think!
