The heavy soul-guiding panel was laid out on the experimental table, and then the teacher surnamed Liu brought over a few instruments to clamp the panel tightly.
After securing it to the table and making sure it wouldn't move, he picked up a golden carving knife. Cao Yu could clearly sense that the quality of this carving knife was probably not much inferior to his own.
An Level 8 Soul Engineer would certainly have a fine carving knife, and of course, some Soul Engineer would spend a lot of money to collect valuable carving knives.
The golden tip of the blade landed on the panel without making a sound. A Golden Wolf could be faintly seen engraved on the blade, making it both magnificent and imposing, truly a work of art.
While engraving, Teacher Liu said to Cao Yu beside him in a deep voice, "Today I'm going to teach you how to engrave five different Soul Guidance Array on a metal panel. Listen carefully and learn well."
Five kinds?
This metal panel isn't very thick, is it? It's only about half a centimeter thick. To inscribe five different magic arrays on this panel would obviously be very difficult.
Teacher Liu wasn't in a hurry. He first brought out another instrument from the side and then introduced it to Cao Yu, saying, "You can use this instrument to assist your seal carving work later. Of course, someone like me who has already accumulated a lot of experience doesn't need it."
Cao Yu took the instrument without any hesitation. He found that most of the instrument's frame was made of ordinary metal, with two pieces of glass embedded in the middle.
Objects placed below can be magnified, but the image is very blurry. Clearly, the purity of the glass material is not ideal, and it contains a lot of impurities.
"The Sun Moon Empire is quite impressive; they've already developed a weakened version of the microscope so quickly."
Cao Yu smiled slightly, because the research institute had already developed this device not long ago, and it was many times more accurate than the instrument in front of him.
However, the Sun Moon Empire's research and development capabilities are still commendable.
Before long, we could see that Teacher Liu had engraved a shallow mark on the metal panel.
"What I need to do now is divide this panel into five layers. The first layer is the simplest, but the remaining four layers are more difficult, and it's easy to make a mistake if you're not careful." While he was speaking, Teacher Liu had already completed most of the first layer.
The engraved magic array wasn't very complex; it was just a simple level four acceleration array. Teacher Liu chose this relatively simple one because of Cao Yu's Soul Engineer level.
The magic array is simple, but that doesn't mean the seal carving work itself is simple.
The difficulty lies in carving out five layers on a metal panel that is only half a centimeter thick.
More than forty minutes passed, and the five-layered magic array had been completed. Teacher Liu blew away the debris on the panel and then handed it over.
"Test it with your Soul Power and see if it can be activated normally."
Cao Yu poured his Soul Power into the Soul Guidance Array as instructed, and then saw that all the arrays emitted a faint light, clearly indicating that they had been successfully created.
That's impressive, since none of them failed.
Upon closer inspection, I discovered that each layer was thinner than a strand of hair, and then I gently pinched it with my fingers.
He discovered that the seemingly fragile material did not deform, and continued to apply force until he used 60-70% of his strength before he felt the material begin to deform.
But when he let go, the metal panel bounced back and returned to normal.
Teacher Liu smiled and said, "This new type of metal material was developed not long ago. We have all discovered that this material has the characteristic of memory rebound and is very difficult to destroy. However, the only drawback is that it cannot be mass-produced at present."
"Come on, it's your turn." He made room for Cao Yu, took out a new panel and fixed it on the lab table, then began to instruct Cao Yu on his seal carving work.
An hour later, after several attempts, Cao Yu finally managed to inscribe three layers of magic arrays on the metal panel.
This result is not good; it only ranks in the middle to upper level among all the Soul Engineer who came to participate in the training camp.
Among them, the local students of the Sun Moon Imperial Soul Engineering Academy achieved the best results.
However, Teacher Liu, who was standing to the side, said in a gentle tone, "I heard you were Martial Soul Master before? That's a good result. Keep up the good work and try to get above the fourth level."
Cao Yu gently patted his shoulder, smiled, and then took out a new panel to continue engraving.
Around six o'clock in the afternoon, the bell rang to signal the end of get out of class. All the students put down their carving knives and got up to leave.
Everyone benefited greatly from this training camp, and many trainees packed their belongings with satisfaction, although of course, the metal materials were not allowed to be taken away.
He Caitou came over at this moment. They originally wanted to invite Cao Yu to eat in the canteen, but Meng Hongchen had already come to Cao Yu's side.
They could only awkwardly wave and say, " Cao Yu, we'll be leaving now. We won't disturb your time together any longer."
Cao Yu smiled and said, "Alright, see you tomorrow."
"Let's go, Meng." He took Meng Hongchen's hand, and the two smiled at each other. Then Meng Hongchen leaned on his shoulder and slowly walked away.
As you walk out of the gate, you'll see many students already hurrying towards the cafeteria.
Their running style perfectly matched the temperament of those who work hard; everyone was roaring and charging forward with all their might.
It was said that the Soul Engineer's courses were very mentally taxing, and Cao Yu only realized this was true after experiencing it himself. Once their mental energy was depleted, they would easily go hungry, so every time class ended, the students would long for the food in the cafeteria.
As Cao Yu walked, he looked at Meng Hongchen with affection, then asked, "Meng, how many levels did you complete this afternoon?"
Meng Hongchen gestured with her fingers and chuckled softly, "Only four layers. Although the last layer was engraved, it didn't work. My teacher said it's because that layer broke."
"By the way, what about you?" Meng Hongchen looked up at him, then couldn't help but reach out and press her finger against Cao Yu's dimple.
"Wow, you have dimples!"
"What, is it strange to have dimples?" The girl's mind raced, and the speed at which she changed the subject almost caught Cao Yu off guard.
Meng Hongchen said with a smile, "But my brother and grandfather didn't have that."
At this moment, Cao Yu suddenly coughed and said in a serious tone, "There's a saying in my hometown that boys with dimples are generally very handsome, like me."
"Ew~~ Aren't you shy at all?" Meng Hongchen rolled her eyes at him, but before she could react, Cao Yu reached out and pinched her cheek.
"Don't you have dimples too? Oh, right! There's a saying in my hometown that girls with dimples are generally incredibly beautiful, and look at you, aren't you?"
Meng Hongchen stopped, then stood on tiptoe and couldn't resist kissing him.
After gazing into each other's eyes for a long time, a deep affection shone through her beautiful eyes. "How can your words be so sweet?"
