Wearing the standard robe of an academic mage, Xi Rui would often be surrounded by other passers-by with a distance of more than one person, and when everyone passed by him, they would also subconsciously lower the volume of their speech and walk by quickly.

Ciri came to Kellila City mainly to participate in the auctions here. There are many mercenary groups stationed in the huge kelilla, and these mercenary groups and other scattered mercenaries can harvest many magical materials from various adventure locations and even the different planes every day, and the rarer and more exotic materials will be sent to large and small auctions.

Ciri has been in contact with various major auctions, and when there are magic materials that meet Ciri's requirements for auction, the merchants will notify him to participate.

The previous few times Ciri was not satisfied, either the hardness was not enough, or the magic transmission efficiency was not good, this time he hoped to find a magic material that met his requirements.

The target lot will be auctioned at the Green Scale Auction House. The Green Scale Auction House belongs to the Green Scale Mercenary Group, one of the few high-level large-scale mercenary groups in the country, --- the Green Scale Mercenary Group, and the material that Ciri focuses on this time is also a magic material obtained by the team during their adventures in the Alternate Plane.

Xi Rui came to the Green Scale Auction House and waited for a while, and the auction officially began. There were all kinds of people in the audience who participated in the auction, merchants, warriors, combat mages, etc., and there were also academic mages like Ciri, and the number was very small, only a few people.

The goods auctioned on the stage are even more varied, all kinds of rare ores, magic plants, strange monsters, monster materials, magic potions and magic props, etc., as long as the value is high, they will be auctioned. Generally speaking, the higher the value of the magic material, the more it will be auctioned later, and the kind of magic material that Xi Rui is aiming at alone is enough to be the finale product in terms of the speed and efficiency of mana transmission. However, this material is too hard, and according to preliminary estimates, even academic mages who are good at the analysis and utilization of magical materials must reach the title of associate professor or above before they can be transformed and utilized.

Associate professor-level academic mages, most of whom have never seen them in their lives, how could they find such a master to help them deal with the materials. Even if you can find an academic mage with the title of associate professor, the other party is willing to help you deal with these materials, and the price is not affordable for ordinary people.

For all these reasons, this magical material is scheduled to be auctioned in the middle part, and its starting price is also very low. However, when the host on the stage informed everyone of the hard properties of this material, called the Shadow Demon Stone, the atmosphere that had been mobilized because of its excellent mana transmission speed and efficiency instantly froze.

The processing requirements of the Shadow Magic Stone are too high, and everyone can only apply the fist-sized Shadow Demon Stone as a whole, which is completely impossible to process, and it is almost a high-priced ornament to buy back. In the end, Ciri got his wish and bought the material called the Shadow Demon Stone at the reserve price.

Although it is the reserve price, the price of the Shadow Demon Stone is not cheap, it cost Ciri more than 2,000 Mithril (that is, two-star gold) to buy it, and no matter how low the Green Scale Mercenary Group is, it will not be sold.

The Shadow Demon Stone is the spoils of the Blue Scale Mercenary Regiment's adventures in the Alternate Plane, and it comes from a strange magical beast called Shadow Fiend. The whole body of this demonic beast is as erratic as a shadow, and it has no substance. Shadow Fiend blends into the shadows, has a very strong attack, and has excellent defense. Its own intelligence is not low, and its escape ability is also first-class, and the Green Scale Mercenary Group paid a lot of money to kill one with a trap, and the Shadow Demon Stone is the only trophy left behind after the death of the Shadow Demon.

Originally, everyone thought that the unique magic materials that had been harvested with so much effort would definitely sell for a good price. After being tested by professionals, the magic power transmission speed and efficiency of the Shadow Demon Stone can indeed be worth dozens of stars of gold, but the too hard texture of this material makes the processing difficulty rise sharply, and the value of the material has also dropped significantly.

The high-ranking academic mages who can process this material have their own trading channels and will hardly come to Kellyla. Although the customers who come to participate in the auction are greedy for the magical properties of the Shadow Magic Stone, no one is generous enough to spend a lot of money to buy a "handicraft" that can only be seen but not used.

After repeated auctions, the reserve price of the Shadow Demon Stone has also dropped to the two-star gold freezing point, which is only enough for the consumption of that battle, not even the round-trip fee. After so many intermittent auctions, the deputy regimental commander who commanded that battle already planned to buy it out of his own pocket as an ornament if he couldn't sell it again, reminding him of this lesson. Fortunately, Ciri bought the Shadow Demon Stone, although the price is low, it can be regarded as a psychological comfort for everyone.

High-potency magic materials have always been sky-high, but thanks to the Numer Profiler, which has been providing Ciri with more and more income, otherwise this one material would have been enough to break his fortune. Mages belong to the profession of burning money, and academic mages belong to the profession of burning Nair memory cards directly.

After transferring money in the background, Ciri directly put the Shadow Demon Stone into the storage space and returned to the Flower Academy through the teleportation array.

After returning to the academy, Ciri did not go to the laboratory, but used the council authority to teleport himself to another place, which was the personal testing ground of Associate Professor Bird, who had helped him study the [Numerical Profiler Type IIIa] spell move prediction function together.

The texture of the Shadow Demon Stone is too hard, and Ciri herself has nothing to do with it. But there are many advantages to being high without weight, for example, now he asks Associate Professor Bird, who is a colleague despite the huge difference in strength, to help deal with this material, which is very simple, very easy. For others, it was not easy to meet Associate Professor Bird.

Starting as a teaching assistant, the academy will help the academy mages open up their own testing grounds. From site construction, to staffing, instrument purchases, the Academy of Magic will provide support. After the completion of the test site, the later maintenance and assistant salaries will also be borne by the Academy of Magic. Even if the title of teaching assistant can be regarded as the high-level main force of the academy mage, the salary will be rapidly improved.

The experimental site at the level of associate professor has expanded to the size of a small city, and there are not only various mage assistants in it, but also many maintenance service personnel. When Ciri contacted Associate Professor Bird, he was teleported directly to his central laboratory, and the two met in a lab that they didn't know what to do.

Professor Bird was very enthusiastic, and as soon as they met, he gave Ciri a bear hug, and then said with a smile: "Little Ciri came to me for something, what, do you want to give up your research on the summoning system and join the arms of our elemental department." ”

Professor Bird has always preached to Ciri how powerful the elemental system is, and the earth-based element is the most powerful of them, as long as you learn the earth-based spell well, no matter how you attack, it will only be an itch in your boots.

At first, Ciri would argue with him a little, but then the two became familiar with each other and listened to it a lot, so they didn't pay attention to this stubble, and this time was no exception, Ciri went straight to the point: "Old Bird (Bird has repeatedly asked Ciri to call him that, the two are colleagues, so it doesn't seem so raw), today I am looking for you, but I have something serious to ask you to help." ”

After saying that, Ciri took out the Shadow Demon Stone and the design plan that had been prepared for a long time, handed it to Bird and continued, "You help me process this material into the size and shape of the design plan, and then find an assistant to engrave all the basic elements with rune patterns." When that happens, how about I give you the first prototype of the Numer Profiler you've always wanted?"

Associate Professor Bird has a heavy collector's addiction and has always wanted a prototype product of the Numerical Profiler, but Ciri feels that this thing is very valuable to his memorial, so he has never given it to Bird. Now I have to ask for help, and I have to endure the pain of cutting love.

Bird's eyes lit up, and he checked the Shadow Magic Stone and the design plan, and directly assured that there was no problem, and asked Ciri to prepare the prototype and wait for him to get the news. After discussing the matter, the two chatted for a while, and Ciri left the test site directly and went home.
