As for the [Forbidden Stone], which is also a time-type magic prop, the [Forbidden Stone] that accidentally appeared during the development of the [Imperial Time Acceleration Orb], it is not easy to price.

The direct effect of the [Forbidden Stone] is undoubtedly much stronger than that of the [Imperial Time Acceleration Orb], which is undoubtedly very powerful when it permanently destroys or damages the magic item equipment and abolishes the equipment item effect.

However, the [Forbidden Stone] is not without weaknesses, and after careful research and experiments, although he has not yet figured out the specific operation principle of the [Forbidden Stone], he has found some related characteristics.

The effect of the Forbidden Stone is affected by the material and stability of the Magic Equipment item itself. Its corrosive effect on magic items and equipment is a kind of time corrosion. If the material cannot stand the test of time, it will be severely corroded by the [Forbidden Stone] and will be scrapped directly. If the material is stable and is not greatly affected by time, the corrosion damage effect of the [Forbidden Stone] will be reduced a lot.

Another thing that has an impact on the [Forbidden Stone] is the stability of the rune circle system in the magic item equipment.

Generally speaking, the older the invention of magic item equipment, the more stable its internal rune circle system will be after generation of improvements, and the less likely it will be completely destroyed by the [Forbidden Stone].

On the contrary, some magic props and equipment that have been researched and invented in recent years and become popular have a poor degree of stability, and can easily be completely destroyed by the [Forbidden Stone] and directly scrapped.

However, even for the most perfect Magical Items, the Forbidden Stone can prevent them from taking effect for a period of time, except for time-based Magical Items.

Xi Rui once used the [Forbidden Stone] on the [Imperial Time Acceleration Orb], and found that the [Forbidden Stone] had little effect on time-based magic items, only reducing their energy and reducing the duration of their effects, and had no other effects at all.

Despite its various flaws, the Forbidden Stone is still a powerful magic item. Except for special circumstances, the [Forbidden Stone] can destroy most of the magic items and equipment of the Demon Soul Mage (the same as the academic mage with the title of associate professor) and below, and the magic item equipment of the Demon Soul Mage (with the same title of professor) can be inhibited from exerting its effect for a short period of time, even if it cannot be permanently damaged.

What is the effect of the upper level, Xi Rui has no chance to experiment, according to his guess that the effect may drop significantly, after all, the strong man who surpasses the demon soul mage, and the magic props and equipment he carries are all high-quality.

Demon Soul Mage and Demon Soul Mage level powerhouses already belong to the main class in the individual planes, and the effect of the [Forbidden Stone] itself has made its effect much greater than that of the [Imperial Time Acceleration Orb]. However, the effect of the [Imperial Time Acceleration Orb] is almost not affected by other factors, and it is very popular with personnel with higher combat power, so the price is relatively high. The advantages and disadvantages of [Forbidden Stone] are relatively obvious, and it is really difficult to price.

Ciri walked around the seventh floor of the central area for several days before finally pricing the [Forbidden Stone] at 15 City Points. These two magic items Ciri didn't have much to prepare, and after reserving a few pieces, all the rest were sold just enough to pay the entrance fee of DeWitt's time study course with 100 city points.

After setting the selling price, Xi Rui spent one point to apply for a short-term small booth on the seventh floor of the central area from the Everything System.

Of course, the small stalls in the City of Death are not like the stalls of ordinary people, but are actually a temporary consignment system. The seller hands over the product to the system, and then sets the name, price, type and product introduction, and the system will display the product in a fixed area for a period of time. If someone buys everything, the system will automatically complete the transaction and assign the city points to the seller.

There is no transaction fee for small transactions, only a booth rental fee, and a commodity transaction tax is levied on large-scale transactions.

Before he made any money, a point had disappeared in front of Ciri's eyes. To be honest, Ciri is really a little distressed, one city point is enough to buy a lot of magic materials on the first floor, and he can only rent a small stall for a period of time on the seventh floor. But he had to go on a loan, because there were very few buyers on the first floor who were interested in these two things and had enough City Points to spare. If you don't give, you will never be rewarded, and Ciri can only comfort herself with this.

After renting the booth, Ciri wrote the names, pricing, categories, and specific effects of the two magic items in the corresponding positions.

[Imperial Time Acceleration Orb] is a time-based magic item, and Ciri should mark the acceleration multiplier and action time. [Forbidden Stone] Ciri is not marked as a time-type magic item, because many of the [Forbidden Stone] don't look like time-based magic items, and it is a by-product of experiments, and Ciri has not figured out its specific principle until now, so it is classified as a special type of magic item.

Special types of magic props generally have complex components and unique functions, which are difficult to classify, and [Forbidden Stone] fully meets these characteristics. There are treasures and garbage in special types of magic props, and what you can find depends on luck. Ciri finally marked the known effect of the [Forbidden Stone], and after submission, the two magic props will be reviewed by the Everything System for a period of time before they can be officially sold to the public.

I don't know how to review the system of everything, anyway, it can roughly simulate the effect of magic items, and avoid a large influx of fake and defective products, otherwise others would not dare to buy those messy new products on the seventh layer.

The review efficiency of the system of all things is very high, and soon the two products are officially displayed and sold to the public, but the display location is a bit biased, in the corner of a peripheral area.

There are also many fixed shops on the seventh floor, and even some shops have been permanently bought by certain organizations and individuals, provided that there are enough city points.

City points are the universal currency of the city of the end, no matter where it is, it is impossible to have money, but it is impossible to have money.

As for the sales of the [Royal Time Acceleration Orb], Ciri has no worries. Time magic items have always been a sought-after product in the market, and many people will search for the location of these magic items from the Everything System to buy them. Moreover, Ciri's price is slightly lower than the market price, and it should be sold all of them soon.

The sale of [Forbidden Stone] Ciri has always been a little worried, after all, customers are inevitably a little suspicious of these new special magic items, even if there is a systematic review of all things. The audit of the system of all things is not omnipotent, and there is a small chance that it will make mistakes, and if you are unlucky enough to encounter some defective products, you will lose a lot.

The small booth provided by the Everything System does not need to wait for the seller himself, so after Xi Rui dealt with this matter, he returned to the Blossom Academy for experimental research, and the research progress of the [Level 3 Intelligence Core Sequence] has been relatively tight.

A few days later, Ciri returned to the City of the End to check on the sales, and found that the [Imperial Time Acceleration Orb] had been sold out as expected, and the [Forbidden Stone] had not been sold.

Now Xi Rui has only received 40 points in payment, and the other four [Forbidden Stones] on consignment have not moved.

Ciri wanted to lower the price, but she couldn't do it, so she hung up the few self-belongings she kept. However, in the end, he felt that this was too much of a loss, the effect of the [Forbidden Stone] itself was very strong, and he had already set a relatively low price because there was no similar product, and he was really sorry for the effect of the [Forbidden Stone] if he lowered the price.

In the end, Ciri gritted his teeth and did not change the price. It really didn't work, so he went back and exchanged the Forbidden Stone with the Flower Academy for something to sell.
