The new version of the numerical detector will take a period of time to be produced before it can be put on the market, and Fanhua Academy has handed over the production task to other cooperative organizations to specialize in the production of high-end numerical detector products.

Cirry has tweaked some of its high-end products to make them easier to work with. These products will be supplied exclusively to the Alchemy Golem mages of the Flower Academy, allowing them to connect to their own Alchemy Golems to improve their combat effectiveness.

In the continuous experimental research of the [Level 3 Intelligence Core Sequence], Xi Rui will also take a little time out of his busy time to understand the City of the End.

Since Ciri is an official citizen of the City of the End, he can teleport directly to the ends of the earth, so it is relatively convenient to go back and forth. Ciri's way of learning about the City of the End is simple, it's just to hang around.

Time is limited, and Ciri mainly browses between the seventh and first floors. In the first layer, there are a lot of magic materials that he can use, and on the seventh floor, Ciri prefers to browse the endless knowledge in the knowledge tower, even if he doesn't have any city points and can only read the catalog of these knowledge, it also makes Ciri gain a lot of knowledge.

All the knowledge materials in the Tower of Knowledge need to cost a certain amount of city points, and according to the preciousness of knowledge and materials, the required city points are also different. What Ciri is most interested in and needs most right now is temporal knowledge, which is one of the most expensive types of knowledge in the Tower of Knowledge.

After a long period of browsing, Ciri fell in love with one of the courses on the systematic teaching of time science.

There are three types of knowledge materials in the Tower of Knowledge, which are generally divided into three ways.

The first is to directly instill the content of the knowledge into the buyer's mind, regardless of whether you understand it or not, as long as you remember it. This is the easiest and cheapest way to transfer knowledge. For some historical records, the materials that are not difficult to understand are generally taught in this way, and the knowledge content that needs to be learned and understood is generally not used in this way.

If you need a lot of knowledge, it takes a lot of time to understand it on your own, and it's not worth the cost. At this point, you can choose the second or third way to buy.

The second type of knowledge includes the content of the teacher's own understanding and commentary, which you can understand based on the other person's commentary. There is an image of the other party in the Tower of Knowledge, which can answer many questions from the buyer based on the information left behind by the imparter under the control of the system of all things.

Of course, the image is not the person after all, and it is impossible to answer all questions, so if you want to fully learn what the imparter knows, you can choose the third way.

The third type of teaching is known as "master-apprentice" teaching, which means that both parties transfer knowledge like a traditional master-apprentice. Of course, the two sides will not really form a mentor and apprentice, but the way of teaching is no different from that of ordinary mentors and apprentices.

The purchaser needs to go to the plane where the imparter is located, live and learn by his side for a period of time, during which he can continue to ask the other person various questions until he thinks that he has fully learned this knowledge, and then he can pay back.

Instructors usually start with a simple price range for the course, and then decide on the price based on the difficulty of the delivery process.

The third method of teaching is the chronological system teaching course that Ciri has a fancy eye, and the teacher is --- DeWitt, a Terran mage from the plane of Leith. In the Tower of Knowledge, there are a large number of time-related knowledge materials sold by himself, including time-related materials at various stages, and various time-study spells. Drenthe himself should be a powerful chronomage.

The time learning system teaching course that Xi Rui is interested in, Drenthe will decide the specific price according to the difficulty of teaching and the amount of knowledge taught, up to a maximum of 1000 city points, and support new young mages to pay the balance in installments, and only need to pay 100 city points for the entry learning fee at the beginning.

Compared to other imparters, Drenthe was clearly encouraging and supportive of young mages. The price of the time learning spell materials he sells is about the same as the others, but the price of this basic teaching knowledge is much lower than that of others. Apparently Devit encourages gifted people to join the ranks of Time Mages, which is why they put such a low price tag on this kind of basic knowledge.

Basic teaching is often more cumbersome than teaching finished spells, so none of the other mages have a price below 1000 city points, and many are more expensive than the spell price. Only DeWitt apparently chose such a low price because he encouraged the addition of new blood to the time, and it could be paid in installments.

However, for Xi Rui, he does not have the entry fee of 100 city points, and Xi Rui only has 5 city points given by the early stage of the Everything System. 5 city points are actually a lot, a lot of unprocessed magic materials, 5 city points can buy a lot of them.

The most expensive thing in the City of the End is technology and knowledge, and the raw materials are not very expensive unless they are peerless. After all, there are countless planes in the wizarding world, and the situation in each plane is also different, maybe the magic materials that one plane cherishes very much, and grab a lot of them in other planes. Therefore, on the whole, there are not many magical materials that are cherished by the wizarding world in general, and only varieties that are difficult to obtain or materials that are scarce in all planes will have a higher price.

There aren't many things Ciri can get her hands on in the City of the End right now.

Numerical probes are not helpful for high-end combat power due to the limitations of probing techniques, and people with low strength generally don't have many city points.

[Fortress] belongs to Ciri's personal exclusive magic items, he will not sell them, and Ciri will not have time to copy the second [Fortress] in the short term, and he will not be able to help Ciri earn City Points.

The knowledge of the [Logic Module] is in its infancy in the Colin plane, and few people in the City of the End have heard of it, and no one will pay a high price to buy it.

After all, it seems that there are only two time-type magic items, the [Imperial Time Acceleration Orb] and the [Forbidden Stone], which should be able to sell for a higher price.

Due to the increased proficiency, Ciri was able to craft two time-based magic items much faster. Several council members' orders for [Forbidden Stone] have been delivered, and he has also made some two kinds of props to prepare for his own backup, and it seems that he has to take them out and sell them in exchange for city points.

Time-based magic items are high-priced products even in the City of the End, and Ciri's [Imperial Time Acceleration Orb] is the lowest-end and most common time-type magic item, and it can only unilaterally accelerate material time, and cannot increase the speed of thinking. However, it is difficult for ordinary people to feel that the speed of thinking has not accelerated, so it can still be sold as a normal time-accelerating magic item.

The [Imperial Time Acceleration Orb] can only speed up the time flow rate of the user's matter by about twice the time flow rate, and the duration is short, which is considered the lowest-level time-type magic item. After a careful examination of the market, Ciri finally priced it at 8 city credits. This price is lower than that of products with the same effect, after all, the [Royal Time Acceleration Magic Ball] has a trick, and at the same time, Xi Rui also hopes to harvest city points quickly.
