Opal, a silica gel gem stone, contains 5-10% moisture.

In the base of the Spell Department under the night, in a standard suite bedroom in the dormitory building, Gu Jun was looking at a crystal-colored opal in his hand.

There are two types of opals: change color and unchanged color. This one is change color, elliptical, 4.5m long and 2.1m wide, and its origin is in western Australia. This is what he specifically told the people of the Recreation Club to pay attention to when buying it, because he believed that "Walton Town" still has another meaning.

Since opal is amorphous, some structures will discolor or even crack due to lack of moisture, but there will be no changes if the structure is stable.

This one has a full and full moisture, bright colors, and a round body. He thought this would probably meet the requirements of the "Naket Manuscript".

"Um." Gu Jun took this gem and sat down at the work table specially placed in the middle of the bedroom. The table was filled with carving tools, engraving knives, electric drills, drill bits, grinding needles... like an orthopedic surgery treasure box.

And in the corners, he installed the camera himself, which would record his next situation.

In fact, Gu Jun didn't know what he would do, he only knew that he was going to carve an old seal on this opal.

But he has no idea how to carve and how it can have a possible effect.

It is a technique for using old seals recorded in that chapter of "Naket's Manuscript". Unlike the large old seal stone, it is used to "monitor rationality."

Gu Jun understood this way, because the content of the text above was too obscure and difficult to understand, and he was just half guessing and half confused.

However, "rational, rational, rational", he could see how much the civilization that created these technologies valued this point. Reason was their highest key, and knowledge and science were the only way they were willing to understand the universe.

Therefore, if you want to use a metaphor for this kind of tool for monitoring rationality, it may be like a human health watch that can see how many steps you have taken.

"But this kind of gadget is a guy." Gu Jun thought, "If it can be really made, it can solve our big problem."

The paintings in "Naket's Manuscript" clearly define the patterns to be carved, but each one seems to contain the most superb mathematical rules. The strange precision even made him feel the insignificance when he looked up at the starry sky, which was by no means a science that humans can understand at this stage.

Just like a primitive man does not understand what calculus is. Although he doesn't understand it very well, high mathematics always gives him a headache.

"Try it." Gu Jun took a deep breath and picked up a carving knife. He felt very comfortable when he used it for the first time. The calm hand could also work here.

He had already told Cai Zixuan, who had been staying with him, and never let anyone come in and disturb him until he went out.

Gu Jun closed his eyes and opened the "Naket Copyright" in his mind. He turned to the number of pages about the creation of "old seal ornaments". He looked at those lines that were beyond imagination, indescribable patterns, and how to combine mental power with opals, scheduling the moisture in the stone, and reshaping the structure...

Gradually, his mental power became concentrated and he gradually had a headache.

"Um..."

It seems that many dreams are coming, replacing darkness.

Gu Jun looked around and found that he stopped in the grand vaulted library again, but it was not the last time he was, nor did he have the shadow of the last time.

The rows of huge bookshelfs were far away. He was standing next to a wall, emitting a faint light. He saw that the huge stone wall was covered with carved patterns, like scratches constantly rubbed with frosted paper, layer by layer, mottled and intertwined, many times more complicated than those in "Naket's Manuscript".

"Are these...the technical principles of monitoring stones..."

The more Gu Jun looked, the more he was shocked by a delicate and exquisite force. Every straight line and curve on the wall seemed to outline his soul.

He looked at these carving lines and quickly entered it. He didn't feel any discomfort, so he forgot about time...

I don't know how long it has passed, but when he slowly stretched out his right hand and wanted to touch the wall.

Suddenly, the illusion receded, and Gu Jun suddenly opened his eyes wide. There was no longer a grand library or a spacious bedroom in the dormitory.

However, the sky outside the window had become brighter, and the clock showed that it was around six in the morning and a night passed.

"Ah..." Gu Jun took a deep breath, as if he had reconnected his body. An extreme feeling of fatigue surged, causing him to fall head-on on the work table. Especially his arms, it was sore that it seemed as if it was about to break...

What made his third-level calm hand become like this?

Gu Jun's heart suddenly jumped and he lowered his head to look at the work table. Did I carve something?

I saw that there were a lot of fragments of stone chips on the table. His right hand was still holding the carving knife, and his left hand was holding the opal.

It is still an oval shape and has not undergone any major changes, but it is just carved with an old seal pattern on the front. It has not been polished yet, but it seems natural. Everything is just right, and the horizontal branches of the old seal are even connected to its different colored figures.

"This..." Gu Jun frowned, and found that the tools such as electric drills had not changed. Did he use this carving knife all night?

He plucked up his strength to hold his feet up, and his feet were exhausted, but he walked to the computer and turned on the surveillance video to watch. He saw that after he began to sense the "Naket Codex", his hands quickly moved and carved the opal with a knife...

He looked at the normal speed for a while, then adjusted the speed to watch, and then he carved it so much throughout the night.

After changing the camera and looking at different angles, Gu Jun found that his eyes were always closed, which was like an activity in a sleepwalking state.

"It seems that I just carved an old print. In fact, this is also a kind of spiritual carving. The structure inside this opal is already different."

The question is, is this small old seal stone effective?

According to his understanding of "Naket's Manuscript", Gu Jun tricked the stone for a while. Seeing its brilliance changing, the old seal pattern flashed again... He couldn't help but laugh happily, and he held the stone tightly and became! It should have been a life-saving medicine.

He immediately went to get his cell phone and called Tong Ye. It was his turn to wake someone up early in the morning.

"Hey?" But Master Tong picked him up very quickly and seemed to be not sleeping. This week, this old guy was busy enough and he was haggard for a few times.

"Tong Ye." Gu Jun smiled, "I finally figured out a technique passed on to me by the Great Elder Atal. Our health watch has come out."

"What healthy watch?" Tong Ye was shocked and suspicious, "Atar can still do this?"

"Healthy watches are a metaphor, which is actually a monitoring and testing equipment for the rational status of the spell personnel."
