At the same time, Xia Lin had already selected the treasures he wanted in the royal treasury of the Dragon Sleeping Palace, and carried the mysterious stone slab in a carriage to embark on the return journey in the gradually descending night of Hurgana.

Although the teleportation cloak had a strong life-saving ability and could play a great role at a critical moment, Xia Lin still couldn't let go of his curiosity about this stone tablet that even the court archmage had not been able to study the mystery of.

According to Archmage Agnes, even Archmage Strach's use of the most powerful Yang Ray of the Six-Ring Plastic Energy spells, or the Golden Knight's burst of combat skills, would have no effect on the slate.

Such a magical performance has even surpassed the divine metal of pure gold, even if only part of the mystery of this stone slab material is studied, it is definitely worth the ticket price for Xia Lin.

Returning to the Carl Institute with this slate, instead of arranging for the study of the slate, Xia Lin first came to Luna's research group to check the research progress of rotation.

Since there are two parts in the expected spell model of the Rotation Technique, namely the main rune module composed of three kinetic runes and the template rune module that refers to the two-ring plastic energy spell Whirlwind, there are a total of five runes, and the connection situation that needs to be considered is not many times more complicated than the one-ring cleaning technique, so the difficulty of research and development has also increased exponentially.

According to Xia Lin's estimate, they needed to conduct a total of 1,326 experiments to find the connection method of these five runes, which was also due to the connection method of the three kinetic energy runes, and the spell model of the one-ring spell Wind Technique as a reference, which greatly reduced the number of repeated experiments.

During this time, Luna's eighteen-member research team has conducted a total of 427 experiments and accumulated a large amount of research data, but it still failed to touch the most critical part of the rotation, but Xia Lin expects that it will be about the end of March to mid-April, and the research and development of rotationation will be completed.

"That's good, let's keep up the good work!"

Looking at the experiment reports, Xia Lin nodded and said to Luna, who already had dark circles on her face.

Obviously, the pressure of the responsibility of being in charge of one direction is still a bit heavy, but it seems that she is doing a good job at the moment.

"Well, I'll do my best! By the way, Director, the number of four-headed demonic beasts we have locked up underground has now increased to six, when can we start researching the spell models in the spell organs in the bodies of these demonic beasts?"

Seeing Xia Lin's satisfied look, Luna finally breathed a sigh of relief, and a slight smile appeared on the girl's face, and then she asked with some hesitation.

"At present, the manpower of the research institute is still a little insufficient, there are fourteen people in the direction of alchemy and golems, and eight people are needed to take care of the demonic beasts and go out to class, and you have eighteen people left, so there is no way to study the demonic beasts now.

The most important thing now is to develop the rotation technique first, and wait until the rotation technique is developed!"

When it comes to this topic, Xia Lin can't do anything, he can't go to the Royal Academy of Magic to collect wool again, so although the current research institute is not manpowered, he can only wait for the academy to advance the matter of graduate students.

"By the way, I also brought an extremely special strange object today, and this strange thing also needs to be studied by a research group as soon as possible."

After checking the progress of the all-important Rotation Technique, Xia Lin immediately prepared to arrange the research topic of the slate, and he took out the magical slate from a small wooden box he had brought with him and showed it to Luna and the researchers.

The slab is about the size of an adult's chest and abdomen, and has an irregular hexagonal shape that looks like a tombstone in a Templar cemetery.

On the front of it, there are three diagrams of straight lines, arcs, spirals, and other lines, which are extremely complex and mysterious, and looking directly at it for a long time will give you a strange feeling as if you are looking at the stars in the universe.

"What is this?"

When Harper saw the slate, he asked with some curiosity.

Although Harper is now the deputy director of the institute, he is responsible for all research-related matters, including the application and purchase of various magical materials

Buying it requires his approval, but at the moment when the institute is understaffed, Harper has to often pick up his job and act as a researcher under Luna.

"This is an unknown stone tablet, the material is extremely special, even the six-ring spell Yang Yan Ray or the Golden Knight's combat skills cannot cause the slightest damage to this stone tablet, if we can solve the mystery of this material, the benefits will be great.

These line drawings on this slate also seem to hide some secrets, and if any of you are interested, you can use your leisure time to do some research!"

Xia Lin explained to the curious researchers.

"Sounds interesting, but Xia Lin, I don't think we'll have time to study this slate!"

After listening to Xia Lin's words, Harper shrugged his shoulders and said helplessly. They were already stretched thin just to study the rotational technique, so where did they have the leisure time to study this stone tablet.

"In that case, why don't you leave it to me and my apprentice first?"

At this moment, Xia Lin's familiar voice came from outside the Rotation Technique Laboratory, and everyone followed the sound to see that it was Sophia, who was in charge of alchemy and golems.

"Long time no see, Sophia! Aren't you still training apprentices in both areas? And I've also given you a task to study logic runes, can you find time to take charge of the research group?"

After greeting his contractor, Xia Lin asked in surprise. Originally, considering that Sophia's researchers were all accepting her teachings, Xia Lin didn't hit her with the idea, but he didn't expect that she would be interested in this slate.

"Their little ones are learning some of the basics right now, and that kind of thing just needs to be given tasks for them.

As for the subject of logical runes, that's the question I came to you to ask this time, Master Xia Lin, are you sure these runes are all of the same type?"

Sophia leaned against the door frame of the laboratory in the silk robe that Xia Lin had worn when she first met her, looking like she was not going to come in, and when she mentioned the topic at hand, she suddenly asked Xia Lin with a little doubt.

"According to our research in the Karl Institute, this conclusion should be fine, the two types of runes that make up the core of the golem's soul are soul runes and this kind of logical rune.

This variant of the Logic Rune is similar to the two Template Runes, with a rather terrible number, and there will also be changes in the number of nodes, which belongs to a very special type of Rune.

But there is one thing that makes me come to this conclusion, and that is that in our experimental data, these logical runes will always have the same coordinates of ten spiritual power nodes."

In response to Sophia's doubts, Xia Lin nodded affirmatively.

Logical runes are different from other runes, the number of their spiritual power nodes is not fixed, so it is extremely difficult to distinguish their types, but the experimental data does not lie, and it is through the analysis of the experimental data obtained before that Xia Lin has come to the conclusion that the Golem's soul core is composed of two runes.

"If you're sure, then I'll continue to study along this path, but I'm not sure if it will produce results, as for the slate, I'm personally interested, and I'll study it in my free time."

Sophia nodded.

"Then this subject will be handed over to you for the time being, and the direction of alchemy will be handed over to you!"

Although he didn't expect what Sophia would be able to do as a full-level alchemist, Xia Lin didn't have enough research resources at hand, so he handed over the slate to Sophia with kindness.
