Plague Doctor

Opal, a silica gel gemstone, contains 5-10% water.

In a standard suite bedroom in the dormitory building at the Magic Ministry base at night, Gu Jun was looking at a crystal-clear and colorful opal in his hand.

There are two kinds of opals: color-changing and color-changing. This one is color-changing, oval, 4.5cm long and 2.1cm wide. It is produced in western Australia. This was something he specifically asked the people from the Recreation Department to pay attention to when buying it, because he believed that "Wharton Town" still had a hint of another meaning.

Because opal is amorphous, some structures may change color or even crack due to lack of moisture, but if the structure is stable there will be no change.

This one was full of water, brightly colored, and round. He thought that this roughly met the requirements of the "Nakite Codex".

"Hmm." Gu Jun took the gem and sat down at the work table specially placed in the middle of the bedroom. The table was filled with some carving tools, such as carving knives, electric drills, drill bits, needle grinding... It was like orthopedic surgery. Treasure box.

And in every corner, he installed cameras himself, which would record his next situation.

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

But how to carve it, and how it would have any possible effect, he had no idea.

It was an old seal application technique recorded in that chapter of the "Nakter Manuscript". It was different from the big old seal stone. Its function was to "monitor rationality."

Gu Jun understood it this way, because the content of the text above was too obscure and difficult to understand, so he only half-guessed and half-confused.

However, "reason, reason, reason", he could see how much the civilization that created these technologies valued this. Reason is their highest priority, and knowledge and science are the only ways they are willing to understand the universe.

Therefore, this tool for monitoring rationality, if you want to use a metaphor, may be like a human health watch-seeing how many steps you have taken when you are fine.

"But this kind of gadget." Gu Jun thought, "If it can be manufactured, it can solve our big problem."

The paintings on the "Nakite Codex" clearly indicate the lines to be carved, but each one seems to contain the most superb mathematical rules. The strange precision even made him feel a kind of insignificance when looking up at the stars. It was definitely not human. Science that can be understood at this stage.

It's like primitive people don't understand what calculus is. Although he doesn't understand it very well, high math always gives him a headache.

"Try it." Gu Jun took a deep breath and picked up a carving knife. He felt quite comfortable using it for the first time, and his calm hand could also work here.

He had already ordered Cai Zixuan, who continued to stay with him, not to let anyone come in and disturb him until he went out.

Gu Jun closed his eyes and opened the "Nakt Codex" in his mind, turning to the pages about making "Old Seal Ornaments", looking at the unimaginable lines, unspeakable patterns, and how to make them The mental power combines with the opal to regulate the moisture in the stone and reshape the structure...

Gradually, his mental energy became more concentrated, and he gradually got a headache.

"Hmm..."

It seems that many dreams are coming, replacing the darkness.

Gu Jun looked around and found that he was once again standing in the grand vaulted library, but it was not the same place as last time, and there was no dark shadow like last time.

The rows of huge bookshelves were far away. He was standing next to a wall. With a faint light, he could see that the giant stone wall was full of carved patterns, as if they had been rubbed with sandpaper. The scratches are densely layered and mottled, many times more complicated than those on the "Nacht Codex".

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

The more Gu Jun looked at it, the more he was struck by the delicate and exquisite power. Every straight line and curve on the wall seemed to outline his soul.

He looked at these carvings and quickly immersed himself in them without feeling any discomfort, so he forgot about time...

He didn't know how much time had passed when he slowly stretched out his right hand, wanting to touch the wall.

Suddenly, this illusion faded, and Gu Jun's eyes suddenly opened wide. The surroundings were no longer a grand library, but a spacious bedroom in the dormitory.

But the sky outside the window has become brighter, the clock shows it is past six in the morning, and the night has passed.

"Ah..." Gu Jun took a deep breath, as if he had reconnected his body, and then a wave of extreme fatigue surged over him, making him almost fall down on the work table. Especially the two arms, they were so sore that they felt like they were about to break...

What circumstances caused his level 3 calmness to become like this?

Gu Jun's heart skipped a beat and he looked down at the work table. Did I carve anything?

I saw a lot of scattered stone chips on the table. He still held the carving knife in his right hand, and the opal in his left hand.

It is still in the shape of an oval and has not undergone any major changes, but it has an old seal pattern engraved on the front. It hasn't been polished yet, but it looks like it's natural. Everything is just right. The horizontal branches of the old seal are even connected with its different colored portraits.

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

He mustered up the strength to push himself up. His feet were very tired, but he walked to the computer and opened the surveillance video to watch it. He only saw that after he started to sense the "Nakter Codex", his hands quickly moved, holding the knife

Carving into opal…

He watched it at normal speed for a while, and then at fast speed. The next whole night, he looked so sculpted.

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

"It looks like I just carved an old mark on it. In fact, this is also a kind of spiritual carving. The internal structure of this opal is different."

The question is, does this little old seal stone have any use?

Gu Jun played with the stone for a while based on his understanding of the "Nakter Codex". He saw its luster changing and the old seal pattern flickering again... He couldn't help laughing with joy and held the stone tightly. , done! It should be done, life-saving medicine.

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

"Hello?" But Mr. Tong answered quickly and didn't seem to be sleeping. This old guy has been busy enough this week and has been haggard for a few times.

"Master Tong." Gu Jun said with a smile, "I finally figured out a technology passed on to me by the great elder Atal, and our health watch came out."

"What kind of health watch?" Tong Ye was stunned, "Atal also has this?"

"The health watch is a metaphor. It is actually a monitoring and testing equipment for the rational state of spellcasters."

Love the Plague Doctor.
