Jia Yi fiddled with the array disk in his hand, one will detect forward, one will detect backward, like getting a novel toy, this thing is now just a toy, can only detect relatively large objects, if it is too small, affected by background noise, it is not very correct, and it needs to be debugged.

"It's useless, just stand on the lookout and look at it, won't you see it all?" said a sailor.

Hewlett hurriedly pulled him to prevent trouble from coming out of his mouth.

Jia Yi smiled for a moment and said, "This still needs to be improved, the detection range is still relatively short, and the sound will be reflected by other things when the distance is long, and it will become blurry." But now the distance is farther than the eyes can see, just so that you can see the results as soon as possible, I chose the nearest one. And this thing is mainly used for when the line of sight is not good, such as foggy weather, at night, and underwater. ”

"Is it okay to even be underwater, and if it's an underwater reef, can you find it?" asked Laverding hurriedly.

It's still more acute to be a captain, and I immediately realized the greatest use value of this thing, at least the greatest value for running boats. For them, with this, they can go through more complicated waterways, and they don't have to rely on experience to avoid reefs, even if they go to new waterways, there will be a certain guarantee.

In fact, being able to detect underwater Kaichi said it, but they didn't listen carefully before, and they couldn't understand it anyway, but now that they see the real thing, although they still don't understand, but at least it looks intuitive, so they start to pay attention again.

"Of course, but there are still some problems, I have to put it underwater, so it is not convenient to observe, and I need to improve it. And when the time comes, it won't be such a blurry little dot, and the image will be clearer. ”

"Then, then—" Old Verding hesitated, a little hesitant.

But Jia Yi knew what he was going to say: "When the production is complete, I can order a copy for you, but you need to prepare the materials yourself." Truth be told, this stuff isn't cheap. ”

It's not that Jia Yi doesn't want to send one, but this thing is really not cheap, not counting the effort spent when researching himself, just one material, there are Mithril alloys, gemstones, and metal diaphragms for generating and receiving sounds, these sets down, almost hundreds of gold, if you count the design fee and labor costs, a thousand gold is estimated to be not enough. As long as the captain of the ship produces materials, it is already very interesting.

Of course, this is also because of the original version, and Jiayi will definitely use alternative materials to reduce costs.

The captain didn't think about letting Jia Yibai give it away, and said, "This is as it should be, it should be, but when will I get this?"

"Hiss~" Jia Yi took a breath, "When will you get it, I really can't say for sure, this thing is not perfect yet, and if you use it, you must be more hopeful to be able to detect underwater movements, this must also be improved, to be honest, I don't know if I can do it when I get off the boat." ”

Jiayi can only be regarded as a prototype in the laboratory now, and there is still a long way to go before it can reach the level of commercial use. It's like before Jiayi crossed, he said that artificial intelligence and quantum computers were hyped, but quantum computers still only exist in the laboratory, and I don't know what year it will be when they want to launch it into commercial use, and artificial intelligence is also more artificial - the so-called no artificial, where can it be intelligent.

Jia Yi thought for a moment and said, "You give me an address, and I'll tell you when this is done, and you can prepare the materials or something, and because none of you have a mage, I also need to design a magic storage device for you, so that you can use it even if you don't have magic power." ”

He didn't have a word to say, he still needed to devise a foolish operation for the old Verdin. He has encountered this problem when designing software before, some functions he thinks are very simple things, very simple and clear, but the customer just can't, think that there is a problem with your design, you can only change it more simply, or write a detailed instructions for use to the customer. Now this magic equipment is even more so, the captain has no contact with any magic equipment at all, some of them seem to be when some people first see the computer, they can't even turn it on.

It is estimated that they will have to be trained in how to use it by the captain, and I don't know if they can understand it if they can only provide a manual.

However, it is not a loss to design a fool's operation method, because in this way he can sell this detection circle to various captains, especially those who run by sea, the sea is more risky and more profitable, and they will not be stingy to buy a device that can ensure their safety and predict the danger in advance.

In the following days, Jia Yi spent all his energy on improving his sonar radar, and even Xiaoqing couldn't take care of it, saying that Xiaoqing was also stuffy on the ship and didn't appear for a long time. But fortunately, Xiaoqing followed Jiayi, who was out of tune, but learned his laziness to a full extent, and stayed in the bullpen every day to eat and sleep, sleep and eat, and his fat grew a layer and he didn't feel bored.

Fortunately, Jia is an honest cow, if it is a husky, whether the ship can be kept is still two words.

In order to explore how bats filter unwanted background noise, Jiayi lets bats fly every day, and uses spells to detect the reaction of bats' ears after receiving sounds. Because the bats have been flying for a long time and are sluggish, Jia Yi also deliberately went ashore to buy some herbs to prepare stimulants for the bats, and he can't care if it will be harmful to the body.

Every day, bats make terrible calls (bats chirp and only emit ultrasound when they are pathfinder). When the sailors nearby heard this, they couldn't help but get angry, and then left far away. Then, because the rumors that had been dissipated during the last test of the magic circle were resurrected. It is said that Master Kaichi finished studying the hearing of bats and began to study the soul of bats.

After a long period of improvement and experimentation, most of the background noise has finally been eliminated, and the detection range has also been greatly improved, in a relatively open water surface, it can detect a distance of more than 10 kilometers, and if it is farther, the accuracy will be greatly reduced, and it is almost impossible to distinguish. And in addition to the surface of the water, Jiayi's detection circle can already directly detect underwater, and when the circle is used, it will stretch out a magic tentacle to probe underwater and make a sound in the water. In this way, there is also a detection range of more than 10 kilometers underwater, and because the water medium is denser, the detection effect is better.

Above and below the water, there are obstacles that are larger than the size of a child on the river, and if anyone tries to touch them at night, they will be spotted immediately.

At this point, the circle has already possessed basic practical value.

It's just that if you are in a complex environment, such as a jungle, the detection distance will shrink sharply to about 500 meters, even so, it is much farther than Ace's detection spell.

It's just that if it's just at this point now, it still can't meet Jiayi's requirements.

At this current level, it can only detect relatively large objects, and the fact that a bat can avoid a rope means that it can at least detect something as thin as a rope. Jiayi hopes that his detection circle can also do this, preferably, to be able to detect the shape of the object, so that he can avoid losing the observed object in a complex environment.

It's just that this requirement is indeed a bit high, and Jiayi has never been able to meet it.
