The rare magic ores in the second floor are much cheaper than the surface space, as they are sold here without being charged a transit fee by the Flower Academy.

With the exception of the Academy of Magic and a few large organizations, ordinary organizations cannot be freely teleported between two levels of space. This area is the only one that can be freely teleported by the Flower Academy, and most organizations and individuals travel between the surface space and the second floor through the Flower Academy.

The Flower Academy charges a portion of the fee for each transmission for non-Academy members, and a separate transfer fee for large quantities of material transmission. Therefore, although the cost of these rare ores produced in the second-floor space is relatively cheap here, and the selling price is not high, the cost of transferring to the outside will go up.

Since the rare ores of the second layer world are relatively cheap, the equipment made from ores as the main material is also cheap. When Ciri and Kayla came out to hang out, they took a fancy to a pair of space gear.

This pair of space gear is two trinkets, a purple women's hairpin and a men's vintage pocket watch, both of which are sold as a set at a low price for couples. Space gear is more expensive in the surface world, as both of the materials needed to craft it come from the inner space.

The core of the space equipment is the Void Gem, strictly speaking, this is a precious Void material, but this Void Material is very difficult to obtain in the fourth layer of space, and it is distributed in large numbers in areas of human activities, so although the price is relatively expensive, it is not as sky-high as other Void Materials. Moreover, each low-level piece of space equipment does not need many of these gems, so although this material is precious, it is not the main reason why space equipment is so expensive.

What really makes space equipment so expensive is that it is not as precious as the Void Gem. The Shaping Stone can only be regarded as a rare magic material, and its main role is to help shape magic items. However, unlike ordinary magic items, the shaping stones needed for space equipment are not a little bit, but a very large number of these ores.

The Void Gem itself is in a state of nothingness with no physical object, and its mining and transportation require the use of special rune circles, and a large number of Shaping Stones are required to condense it into usable space equipment. Due to the large number of Shaping Stones used, the price of space equipment is mainly determined by Shaping Stones.

There is a lot of plastic stone production in the second floor space, and basically all rare mineral deposits will be mined out of some plastic stone by the way, so the price of plastic stone here is very cheap, and the price of the corresponding space equipment is relatively cheap, at least within the acceptable range of Xi Rui.

Xi Rui usually stays in the scope of the Flower Academy, but he doesn't need space equipment, and with his authority, small items can be teleported and summoned inside the academy at any time. However, the two of them may have to go out for a walk at any time, and it is more convenient to buy space equipment. Besides, he didn't spend much on the royalties that the Whispering Chamber of Commerce and the Goddess of the Moon Night would give to Xirui during this period of time, so it was no problem to buy these two pieces of space equipment.

After some bargaining by Kayla, the two got their hands on the two pieces of space equipment as they wished.

Kayla's butterfly hairpin is purple overall, with a beautiful look and a small storage space inside, which she loves. Although Ciri's pocket watch is older and has a smaller interior than Kayla's hairpin, it is much more expensive than that hairpin because it comes with a very practical function--- nihilism.

Void can re-nilize this piece of space equipment, and then attach it to a certain part of the body, which is very convenient and practical. However, nihilism requires a certain spatial talent, which is generally only met by summoning and spatial mages. Ciri happens to be a true summoner, so this pocket watch can be completely nihilized when not in use, which is easy and convenient.

After spending a lot of money to buy two pieces of space equipment, Kayla's "little housekeeper wife" passive attribute attacked, and the awakening "big move" only looked at it and didn't buy it, and the two went shopping for a day, except for this pair of space equipment, which cost a lot of money, they didn't buy anything else.

After the first day of leisure in the second floor space, the two of them slowly began to get busy again.

Kayla has to complete her resignation and handover from the Whispering Chamber of Commerce. Ciri is even busier here, summoning spells requires a lot of knowledge of space-time and contract, which he has to collect, the new [Logic Module] elective course needs to be prepared next semester, the [Logic Module] itself needs to be improved and optimized, and he also subscribes to an authoritative report publication on the latest research results of academic mages, so as not to derail from this world for too long.

Busy is busy, and things always have to be done one by one. At present, these tasks are slow and urgent, and they need to be planned well before they can be completed.

Gathering information on the plane, plane, and contract required for summoning spells is a short-term task, but it needs to be done first, as it is followed by a long-term and arduous task. --- the learning of spatio-temporal and contract knowledge. Only by collecting good information can you learn, only after learning can you master, and only after mastering can Ciri carry out the next step of research on new summoning techniques. So in any case, this aspect of work must be treated as a priority, and this is the future of Ciri.

The basic system of [Logic Module] has been built, but the whole system is not perfect, and the extended application is basically completely blank. Now that Ciri's privileges have been greatly enhanced, he can borrow more and more advanced materials, which gives him the opportunity to improve and upgrade the [Logic Module] system, and perhaps he can also draw on the knowledge and achievements of the Academy's integrated space management system.

As for the elective courses, there is no need to be in a hurry, after all, there is still a period of time before the next semester, and Xi Rui also has some teaching experience, which is the easiest thing in comparison.

Reactivated, Ciri returns to the cycle of going back and forth between the data room and the home.

There is not a lot of spatio-temporal knowledge related to summoning, but the content of each knowledge material is a lot, because every bit of spatio-temporal knowledge is extremely profound, so it needs to be explained a lot, so the thickness of the information naturally increases.

Compared with space science and contract science, the knowledge of time science is more important, but fortunately, Associate Professor Hobert has recommended a lot of materials to Xi Rui, and these alone are enough for Xi Rui to study for a long time. What Hawking's "A Brief History of Time" (just a tribute, but it has nothing to do with the content of the book, and even contradicts the theory, the same below), Heidegger's "Being and Time" (emphasize, just a tribute to the name, please don't bring the theory into the book), Egbert's "The Thing Without Beginning and Nothing", Adelle's "Time, the Power of the Terminal", Vincent's "Mastering Time", etc., are all materials collected by Ciri from Hobert's predecessors.

In the process of collecting these materials, Ciri also accidentally found another document written by the author of the anonymous experimental notes in the Level 5 database--- "Intelligent Core Sequence", and he was ecstatic to quickly borrow the original of this information.
