Kaichi brought the eye armor to the sonar detector and took out a disc and handed it to him.

The sonar detector has been successfully made for a long time, but the best one needs to use the eardrums and wings of the big-eared demon bat as materials, this thing is relatively rare, the most important thing is that it is not sold on the market, and you need to place an order to buy it yourself. So this version of Jiayi is also improved.

On the way here, Jiayi has been modifying the design, looking for a material that can replace the eardrum of the big-eared demon bat, and finally, when he arrived in Beishui City, he found a kind of silver, which is similar to the nature of Mithril, although the effect is far less good than Mithril, but the ductility is very good, after special annealing treatment, the toughness and rigidity are excellent, reaching a nearly perfect balance.

After using Haiyin to make the diaphragm, although it is not as good as the eardrum of the big-eared demon bat, it is also very good, which can be regarded as the third generation, and the most perfect balance of economy and performance at present.

The first generation was used by Kaichi himself, using the eardrums and wings of the big-eared demon bat as materials, and after he improved it, it can now be used not only for sonar detection, but also for detecting the fluctuations of magic power around him, which is much more sensitive than the mage himself. The second generation is a mass-produced version that Jiayi handed over to the Valoka Chamber of Commerce, this is a revision of the first version, but the diaphragm that accepts the sound is of average quality and has the worst effect, but it is already usable and cheap. The third is now pushed out by Jiayi, using the latest diaphragm, and the effect and price are in the middle.

Jia Yi introduced the function of the sonar array disk to the eye armor, and the eyes of the eye armor were shining brightly, if there was this on the way back, it would definitely be smoother. This time is not too peaceful, the eye armor family is also far away from here, even if it is a mage, along the way over the mountains and mountains, across the lake and across the river, it is inevitable to encounter water ghosts and monsters, although there is no big danger, but it is better to find out in advance is safer.

Seeing that he was a little moved, Jia Yi continued to introduce: "A junior mage like us has limited active detection methods, but it is inevitable to go into the mountains and forests to go on a mission, so it is much safer to have this. Moreover, this can also detect underwater conditions, avoiding the danger of unfamiliar waters. You must know that for mages, underwater is a strange existence, and it is easy to have sudden dangers. ”

"You're good, but it's much more expensive than the Valoka Chamber of Commerce. A mage on the side said, apparently he already knew the price, and had seen sonar detectors in the Valoka Chamber of Commerce.

"Then how much is this?" asked Eye Jia, as a mage, theoretically he shouldn't be too short of money, but the place where he used to be was relatively remote, so he didn't have a lot of money, and he was a little sensitive to price.

The mage said, "It costs 160 gold here, and even if it is discounted, it will cost 136 gold, but in the Valoka Chamber of Commerce, it only costs 50 gold, which is more than doubled." ”

"That's because our sonar is better, the distance is longer, the accuracy is higher, and there is no problem with the dense forest, if they are in the dense forest, the detection range will be much shorter. Jia Yi explained on the side, "You must know that many times, the sooner you discover the danger, the more chance you have to deal with it, it is not comparable to dozens of gold coins. ”

The eye-piercing nodded silently.

Sometimes that's the case, it may be just a ten-point performance boost, but it will lead to a doubling of the price, and the two are not proportionally correlated, more often than not, exponentially.

Kaichi continued: "But you don't have to be in such a hurry to buy it, because it's only started now, and you don't have a chance to go to the wild, so you can wait until the end of the semester to buy it." ”

"Hey, what's going on with you, other people's families want customers to buy things, how do you push customers out, do you guys know?" said another mage angrily.

Jia Yi said a little snortingly: "That, I'm the owner of this shop, well, one." The main reason is that our store was opened in a hurry, so the stock is not very sufficient, and if we continue to sell, there is no even anything on the shelves. You see, our shop is relatively small, and we didn't plan to do too much business. ”

"I see..."

For Jiayi's honesty, some people next to him feel that it is the first time to open a store, and it is understandable that they have encountered the beginning of the school season, and some people feel that since they have opened a store, they are not ready, and now they are still stuck with goods and reluctant to sell, which is simply a fraud. However, everyone was a mage, so they complained a few words and didn't say anything excessive.

The beginning of the school season is actually the carnival of those big chambers of commerce, it is normal for small shops like Jiayi to be out of stock, because they can't invest too much money to prepare too many goods, otherwise the products will not be sold, and the money will be pressed there, if the school season is not sold, then the price of reselling to a special chamber of commerce will be much lower, and you have to sell, otherwise the goods are backlogged, then even the funds are trapped, and the loss is greater. It's just like Jiayi, it's the first time that so few goods have been prepared, and before noon, it's about to be sold out, so everyone guesses that they are dissatisfied.

Jia Yi expressed a few words of apology to the people around him, and then he walked behind the counter, climbed directly up to the counter, attracted everyone's attention, took out a stack of coupons, and said: "Originally, it was opened today, and I gave you an eighty-five discount, but the stock was really insufficient, so I sent these coupons to everyone, and everyone with these coupons, you can get a twenty-percent discount on any item you buy next time, and it is valid until the end of the semester." ”

Although it was 80% off, it was more than 85% off, and the term was quite long, but he changed it to only one item that was valid, and this morning he also temporarily adjusted the price and doubled it. If these coupons can win over these customers, they will make a lot of money even if they are discounted.

Fortunately, the customers here are quite reasonable, after all, everyone is a mage, and they are a little self-conscious, and they will not be unreasonable, and Jiayi has publicly apologized and made compensation, so it is not good for them to continue to investigate. Everyone is a mage, and they will have to associate in the future, and it's not good to offend too much. As for those who are not mages, they are not qualified to speak.

Jia Yi saw that everyone was quite satisfied with the coupons, almost all of them received the coupons, even if a few did not receive them, they didn't say anything strange, and couldn't help but breathe a sigh of relief.

This batch of coupons, which is still what Jiayi asked Yangxi to just make, is the engraving of the printed leaflet, brushed with ink to stamp it, and then stamped with the secret key in Yangxi's own mage badge, and after signing, a coupon is ready. Of course, the mage's key can be cracked, but people with this ability will definitely not use it to fake Jiayi's coupons, and they can't afford to lose this person.

"You deceived everyone, just these so-called coupons want to send everyone away? It is said that it is an opening reward, but all of them are out of stock, so you can only send these coupons, what's the use? And your potions, and the Chester Chamber of Commerce logo on them have not been erased, this is not your own goods, is it the way of your store to sell the goods of other chambers of commerce? You're playing tricks on everyone. ”

Suddenly, a voice came out, just when Kaichi himself was just relieved.
