The next morning, at breakfast, Jiayi told everyone the news that the lake would be officially swept soon, and everyone was not too surprised, this matter had been expected for a long time, after all, it was also a threat.

However, Jia Yi said that everyone should participate as first-year freshmen, but it was a little surprising to everyone, after all, the level of new students is uneven, and if there is any accident, it will have a big impact on the reputation of the college.

At this time, everyone also realized that they needed to update their equipment, some people were sad about their wallets, some people were worried that they would not be able to buy the right equipment, and some people seemed confident and seemed to have been prepared.

Morad in the crowd seemed unhurried, he bought equipment when the academy decided to impose martial law after the sea dragon first appeared, although it was not prepared for this operation, but to prevent a demonic beast from breaking into the academy, but now it is also crooked.

He now seems very happy: "You still said that I bought those equipment and wasted it, but now I know that it is not wasted, I have a foresight." ”

"You just say you're afraid of death. Jadery said that although his name and Jade were only one syllable, the two really had nothing to do with each other.

Morad retorted, "Aren't you afraid of death? ”

Seeing that the two were about to quarrel, Xiusley hurriedly stopped them: "Okay, don't fight, you don't have to worry too much, the academy will do a good job of safety, if you can't buy the right equipment, go find your seniors, the equipment they eliminated may be suitable for you." ”

"Do you have the right equipment, Senior Husley, can you sell me? A voice suddenly asked, and Kaichi turned his head to see that it was Rebecca with a freckled face.

In fact, the freckles on Rebecca's face are not too conspicuous, but her complexion is whiter, but it is more prominent, although some people think that freckles are cute, but Jia Yi can't get this point.

Xiusli spread his hands helplessly and said, "I'm really sorry, I just gave the eliminated equipment to Biren yesterday, you should go to the town at noon to have a look, you should find a suitable one." ”

Jia Yi remembered that Xiusli only got the inner armor yesterday, and he should have just eliminated a few pieces of equipment, but he was gone today, and he didn't know who he gave it to, maybe it was given to his old lover.

When breakfast was over, Trudy had not yet returned, and Kaichi filled him with two pieces of brown bread in a cloth bag and a bottle of water for him. It wasn't until they reached the door of the classroom that Trudy hurried over.

Kaichi handed him the prepared food: "Why is it so late?"

Trudy took the food and walked towards the classroom: "Why are the shops in the town opening so late? I went to several stores to buy a necklace with an underwater breathing effect, and the defensive equipment did not significantly exceed my own, so I had to replenish a few scrolls, all of which were frost scrolls and water dungeon scrolls. ”

Both of these scrolls are restrictive scrolls, which are also suitable for use in water, and he does not pursue lethality, and if he encounters a powerful magical beast, attacking the scroll will have no effect other than angering the opponent.

"Maybe it's because very few people go to buy gear in the morning. As soon as Jia Yi finished speaking, he saw the teacher of the history of magic come in, and quickly pulled Trudy, and stopped talking.

As soon as class ended, Trudy began to gobble up, it has been more than two months since the start of school, and after such a long time, maybe this is the first time he feels that black bread is so delicious. Sure enough, I feel good about whatever I eat when I'm hungry.

By noon, the business of the magic props and equipment store, which was supposed to be the off-season, suddenly improved a lot, and many students came over to buy equipment one after another.

Not only Jiayi and their group of newly enrolled students, but also many students from other grades have also come to buy equipment, and it seems that the news has spread. And judging from the speed at which the news spreads, it seems that it is not only the news from Jiayi's side, but also the rest of the students.

Although Jia Yi doesn't need to buy equipment, he can't help but take a look, although there are many people who buy equipment, but it is far less than Jia Yi thought, and although the equipment has risen slightly, it is not big, at most the discount has been canceled, and these chambers of commerce are also more responsible than Jia Yi imagined.

It was completely different from what he expected the price of equipment to skyrocket, and he was willing to risk hanging if he said that the profit reached 100 percent? Fortunately, he did not think that he would take this opportunity to collect equipment and make a profit, otherwise he would not have lost money, but the profit was also very limited.

He didn't know that this was the academy, and all merchants doing business had to consider the opinions of the academy, if someone really raised the price arbitrarily and made the academy dissatisfied, it was likely that they would be expelled from the academy, and they would lose even more at that time.

And all the mages here are, official-level mages, and the potential of the academy's mages is far greater than that of ordinary mages, even if they can't become white-robed mages, it's no surprise that high-level gray-robed mages are not a problem. Usually, it's too late for these merchants to have a good relationship with these mages, so how can they offend them because of this little profit.

In the evening, when Kaichi and the others passed through the street to continue making sonar detectors, they found that even the ordinary townspeople, observers, and traveling mages now knew about it, and Kaichi heard many people talking about it.

The addition of these people has slightly increased the price of equipment, but it is not too excessive. They are not like the students of the academy, the students of the academy are protected by teachers, and the academy must have other security measures, but these idle people, without organization, are not protected by the academy.

If you really encounter danger, you can only pray that there is a teacher next to you and that you are in a good mood to help, otherwise you can only ask for more blessings and run faster than others. These people have a greater demand for equipment, so the price of equipment has been raised.

However, these people have been in the academy for at least a year or two, and there are always some good things at the bottom of the box, although the academy is a safe zone, but when they travel abroad, they are not so peaceful, dangers are everywhere, in addition to Warcraft, there are many people who do business.

Only newly admitted students like Jiayi and them, who originally had a relatively narrow circle of contact with mages, and did not have two good things to accompany them, the demand would be stronger, but there were also local tyrants like Jill, even if they were newly enrolled, there was no room for updating their equipment.

These have nothing to do with Jiayi now, he only cares about whether someone gets the same news as himself, knows the usefulness of the sonar detector, and steals business with himself.

However, he is not completely without advantages, at least for the sonar array, few people are more familiar with him, and the improvement plan is more mature. The students of the academy are all gray-robed mages, and there is no qualitative gap between them, so at this time, the advantage of experience is reflected.

Jia Yi now only hopes that the people who know the mystery of sonar will be a little later, a little later, one point per night, and Jia Yi will have a greater advantage. After three or five days, even if they knew that the academy would use sonar arrays on a large scale, they would only have to start from scratch based on the papers published by Jiayi, and it would be good to be able to make a first edition at that time, let alone compete with Jiayi and them.

When publishing a paper, unless it is a purely theoretical paper, a paper with an inventive nature will not be written in too much detail, as long as the correct result can be obtained in the end, and whether it is the optimal result is not within the scope of the paper. Even if there is none, some mages will bury some small holes in the spell or circle model, and if you really want to build a spell based on the paper, then you need to optimize it slowly.

Although Jiayi didn't bury the pit, he didn't write too much detail when he wrote it, and what he published was the original version of the circle model, not optimized. The reason why he didn't bury the pit was not because of his high consciousness, but because he didn't have that consciousness yet, he didn't think of it at all.

When he first started to publish his papers, he wanted to write every step clearly, for fear that others would not be able to understand and make the correct physical object. It wasn't until he arrived in Memphelbo, when he wrote his thesis on sonar, that he was reminded by Orlando that there was still such an operation.
