Looking at Huo Yuhao, who had started to make soul guides, Lin Jiayi was a little puzzled.

"What does it mean that the carving knife is also part of the soul guide?"

He muttered as he observed the movements of Huo Yuhao's hands.

The first step Huo Yuhao took was the inscription of the core array.

A black metal cube was held in his left hand, and the spare carving knife in his right hand was quickly inscribed on its surface.

Each knife followed the next without the slightest pause. Huo Yuhao's expression did not look like he was thinking hard, but always kept a surging smile.

Lin Jiayi couldn't help nodding secretly.

Looking at this skillful movement and confident appearance, it is obvious that this is not the first time that Huo Yuhao has made this soul guide.

But he couldn't see what kind of soul guide Huo Yuhao wanted to make for the time being.

The inscription of the core circle was soon over, and Huo Yuhao put the metal cube the size of half a palm on the table and began the production of the main body of the soul guide.

Lin Jiayi had already rated Huo Yuhao's performance just now in his heart.

As the teaching director of the Sun Moon Royal Soul Master Academy, he is an eighth-level soul master himself, and he has taught many students, so his eyes are so vicious.

It was just a short observation just now, and he could conclude that Huo Yuhao was a genuine fourth-level soul master.

Lin Jiayi couldn't help but sigh in his heart.

It's a pity that such a soul guide genius does not belong to the Sun and Moon Empire.

Lin Jiayi had a sense of expectation for Huo Yuhao, because he didn't see what Huo Yuhao was going to make.

As a soul master, it's not terrible to have a low level, it's a lack of ideas and creativity that is terrible. If you only copy other people's drawings and don't have your own things, it will also make Lin Jiayi lower the evaluation results a little.

But the soul guide that Huo Yuhao is going to make now has not even seen him.

Huo Yuhao didn't hide anything at all, he showed all his production processes in front of Lin Jiayi so generously, and soon the main part of a "platform"-like soul guide was built.

The square metal countertop has some grooves and fixtures that seem to be intended for placing something.

"Director Lin, I'm done." Huo Yuhao snapped his fingers and said with a smile.

Lin Jiayi frowned, his heart full of suspicion.

He didn't see what type of soul guide it was.

First of all, it will definitely not be an offensive soul guide, nor will it be a defensive type, then it can only be a functional type.

Lin Jiayi only felt that this soul guide had a simple appearance, a bit like a workbench, but he couldn't see any effect at all.

He asked, "What is this?" ”

A wicked smile appeared at the corner of Huo Yuhao's mouth: "This is a fourth-level soul guide independently designed and developed by me, a soul guide machine tool." ”

"You designed it yourself?" Lin Jiayi was a little surprised, his eyes widened slightly, and asked, "Then what is its use?" ”

Huo Yuhao smiled slightly, put the core circle into a square groove on the metal table, and then put the spare carving knife into a circular groove in it.

The handle of the graver is inserted into the metal table, leaving only a sharp blade on the outside.

He took another piece of rare metal from the table and fastened it to the blade of the carving knife.

Lin Jiayi's brows furrowed again, he seemed to be about to guess the function of this soul guide.

At this time, Huo Yuhao took out a baby bottle soul guide from his belt and inserted it into another circular groove on the metal table.

The moment the bottle was inserted, the entire metal table suddenly started to work.

The tip of the carving knife is already in contact with the metal block, and the metal block is stationary, but the tip of the knife begins to move.

Each translation of the tip of the knife leaves a slight scratch on the surface of the metal block.

Lin Jiayi's brain was blank at this time, and his original puzzled expression was completely replaced by shock.

He was all too familiar with what this metal platform was doing, and it was something that every soul master had to know - inscription.

"This ...... This ......"

Lin Jiayi hurriedly leaned down, leaned his head closer, and tried his best to widen his eyes, wanting to observe more closely.

"It's really an inscription."

He muttered.

It's just the simplest of charged core circles, and it's incredibly slow, but it's the standard inscription step.

Huo Yuhao looked at Lin Jiayi, who was shocked, and the corners of his mouth rose slightly.

The idea of using a soul guide to make a soul guide had been proposed by him for a long time.

The soul master of the Star Luo royal family has reaped relevant results at this point, but it is still quite different from his original idea.

Now when he has enough soul power as a foundation, he finally has the conditions to realize the vision in his heart.

After hard thinking, continuous practice and continuous modification, finally, the soul guide machine tool in his hand came out.

Although it has been manufactured, there are still many points that need to be improved, such as the carving knife can actually be changed to a sharp metal piece, the main part can continue to be simplified, and the speed can be much faster, and so on.

But Huo Yuhao didn't have that much time to improve on other aspects, and he focused all his attention on the pursuit of stability.

Lin Jiayi soon discovered another unique point of this soul guide, that is, the entire metal platform did not need to be urged by outsiders to input soul power at all, and it could actually operate on its own.

After a brief moment of stunnedness, he quickly understood what was going on.

The power source for this soul guide is the bottle.

The soul guide machine consumes not electricity, but soul power, and the milk bottle is its battery.

Soul power flowed from the bottle into the metal table, urging the carving knife to inscribe on the metal block, and the soul power also flowed into the core circle through this step.

"Genius design, in this way, no one needs to operate it at all, as long as the soul power in the bottle is not exhausted, then this soul guide can always operate."

It is not new to charge the soul guide with a milk bottle, but Huo Yuhao still surprised Lin Jiayi by integrating it into the production so naturally.

Lin Jiayi quickly understood all the functions of this soul guide machine tool.

The principle is not complicated, but the design concept is absolutely unprecedented.

Lin Jiayi put away his shock, but couldn't hide the excitement in his tone, and asked Huo Yuhao, "Is this really designed and made by you?" ”

Huo Yuhao nodded and said, "Of course." ”

"Okay, I announce that you have passed the assessment, and you are now a fourth-level soul master recognized by our Sun Moon Royal Soul Master Academy."

Lin Jiayi finished announcing, his eyes showed a hint of fanaticism and greed, and he looked at Huo Yuhao with burning eyes: "Quick, Huo Yuhao, give me this soul guide design drawing, say, what do you want?" ”

Huo Yuhao smiled lightly and asked rhetorically, "Director Lin, before answering your question, I want to talk to you first. ”

At this point, the first piece of metal had been inscribed, and he removed it and put the second one on it.

"Actually, I still have a lot of crazy ideas in my head."

"I wonder if the Sun and Moon Empire will support me in bringing these ideas to life?"
