On the Application of the Key of Binding in Soul Tool Construction, the Youngest Level-9 Soul Engineer in History!

"Wonderful! What an ingenious design!"

Gu Yuan looked at the section on the power system in Mo Yuan's submitted blueprint and felt as though all the ideas that had puzzled him before had suddenly become clear.

Beside him, the old man stared at the special array-type Soul Tool shield system Mo Yuan had designed for underwater environments. As he watched, he greedily absorbed the ideas within it.

He specialized in researching Soul Tool shields, yet in front of this blueprint, he could only admit his inferiority. He was certain he could never have thought of such an ingenious combination—one that actually used the pressure of the deep sea to enhance the energy transmission efficiency of a generative Soul Tool shield.

"The younger generation really does surpass the older generation." The third examiner was a middle-aged man who had lost one eye. He was a rare practical combat specialist. Compared with the other two, he was also a Titled Douluo, though one who had reached that level by taking pills.

To be honest, with the assistance of modern Soul-Guided Technology, especially Battle Armor, a person's Soul Power reserves and control could be said to have improved tremendously. For quite a few Level-9 Soul Tools, a Titled Douluo was not necessarily required for their construction.

But he still found it hard to believe that a nine-year-old child could construct a Level-9 Soul Tool.

What kind of joke was this?

If he could really make one, wouldn't that mean all of them had lived for nothing?

After finishing the section of the blueprint in his hands, the middle-aged man was just about to check how far Mo Yuan had progressed with his Soul Tool.

But the other man's speed shocked him.

What the hell? How had he already finished engraving so many Soul Tool Core Arrays onto the components?

Hearing the middle-aged man's exclamation, Gu Yuan and the other examiner, who had been immersed in studying the blueprint, raised their heads and looked at him unhappily, as if demanding to know why he had interrupted their train of thought.

But the middle-aged man pointed into the workshop. "Look at his progress."

"His progress?"

Inside the room, Mo Yuan was holding an engraving knife and rapidly carving a small metal disk.

This time, he had still chosen to make the same Level-9 Concealment Soul Tool that he had previously ruined. He had always felt that this kind of Soul Tool was extremely useful, and now he could just take advantage of the Mecha Engineer Association's resources to make another one for free.

In fact, if possible, he wanted to make several more. Unfortunately, the usually wealthy Mecha Engineer Association had suddenly become stingy in this regard.

Ten thousand years ago, constructing a Level-9 Soul Tool had been almost impossible without a cultivation level of at least Rank 91.

After all, without the vast Soul Power of a Titled Douluo, it was impossible to steadily supply the array's operation while suppressing the violent backlash of the energy.

Even a peak Level-8 Soul Engineer, despite having sufficient technical skill, could not independently complete a Level-9 Soul Tool with insufficient Soul Power. Multiple people had to work together.

Things were different now. Not to mention that advanced Soul Tool energy-storage systems could be used to make up for a lack of power.

Even a person's control over their own Soul Power had improved by several levels compared with ten thousand years ago.

For example, ten thousand years ago, Soul Masters had needed to condense a Soul Core when breaking through to the Titled Douluo rank. Now, they could condense one when breaking through to the Soul Saint rank.

This also reflected the progress of Soul Master theory over the past ten thousand years.

Aside from these factors, the greatest limitation for Soul Engineers was probably Mental Power.

But as luck would have it, Mo Yuan happened to be in the Spirit Abyss Realm, already exceeding that minimum requirement.

The engraving knife in Mo Yuan's hand moved rapidly, engraving the Soul Tool Core Array of the final core.

The knife in his hand was not the one prepared for him by the Mecha Engineer Association. It was the Mimetic Key of Domination. It did not possess any complicated abilities; its sole effect was extreme sharpness, enough to cut through any rare metal.

Finally, as the last stroke fell, he completed the engraving of the Soul Tool's entire core array. All that remained was assembly.

Compared with engraving, the most important step, the subsequent assembly could be handled by practically any skilled Level-8 Soul Engineer.

With a wave of his hand, he dispersed the Mimetic Key of Domination and simultaneously withdrew the binding force from the necklace around his neck.

That was right. The item around his neck was the Key of Binding—Oath of Judah, which he had transformed into a necklace!

This was the foundation that allowed him to construct a Level-9 Soul Tool with only three rings of cultivation.

He used Judah's binding force to suppress the energy of the rare metal in his hands. Under these conditions, engraving became as easy for him as eating. It held no difficulty at all.

After all, the most troublesome backlash of Soul Power had been directly dealt with. Anyone else could do it as well; it was simply a matter of familiarity.

Very soon, under his operation, a metal rod identical to the previous one appeared on the workbench.

After exhaling a breath of stale air, Mo Yuan pressed the button beside him again.

The bell rang once more in the adjoining room, but by then, it was already empty.

The three men had long since rushed to the workshop door. The moment they saw Mo Yuan finish, they immediately burst inside.

The three of them surrounded the metal rod, clicking their tongues in amazement as they examined it.

"Could you introduce the effects of this Soul Tool?" Gu Yuan asked.

"Of course. This is a Level-9 Soul Tool Concealment Device. It can conceal all energy fluctuations within a radius of ten thousand meters. Even if two Limit Douluo fought, they would not be detected."

The middle-aged man immediately thought of how useful the item was.

He looked at Mo Yuan and asked, "Can you sell it to me? Alternatively, I can exchange another Level-9 Soul Tool for it."

Mo Yuan shook his head. "Sorry, I still have a use for it myself."

"All right." The middle-aged man did not insist. Instead, he said, "If I get the chance, could I discuss the technology behind this with you?"

"Of course."

"Thank you."

Meanwhile, the other two men used various detection methods to thoroughly confirm the Soul Tool's rank. There was no mistake—it was Level 9.

Gu Yuan came before Mo Yuan and looked at him as if he were a monster.

After a long while, he solemnly took out a box. Inside was a Soul Engineer badge bearing nine red stars.

"Congratulations on passing the assessment. From now on, you are the youngest Level-9 Soul Engineer in the history of the Federation. Of course, it is probably unlikely that anyone will ever break your record."

After speaking, he handed the badge to Mo Yuan, who pinned it to his chest.

"Do you have anything you want to say?" the white-haired old man asked.

"Nothing much. It's just a little regrettable." Mo Yuan shook his head.

"What is there to regret?" Gu Yuan asked with a frown. Passing the assessment should have been something to celebrate.

"It's a shame that I still went over the time limit and didn't make it in time for the meal."

Mo Yuan pointed to the clock beside them. It showed twelve ten.

"Damn! You monster!"
