Looking at Jiayi's experimental records and the half-finished papers, the more Orlando looked at it, the more he liked it.

"Good!" he couldn't help but pat his leg, "I don't know where the spider's ears are better than the paper on the leg." ”

Orlando stretched the paper in front of Fergus: "Look at Jiayi's thesis, the logic is rigorous, the thinking is clear, and it is better than those papers in the academy who don't know what to say." ”

Fergus had actually been tilting his head to look at it just now, but it wasn't very comfortable to look at it like this, and now when he saw Orlando handing him Jiayi's information, he took it and put it on his lap to look through it.

He looked at it and said casually, "That's a joke, don't always dwell on it." ”

"I haven't seen it, but the ridiculous experimental records aren't much worse than this. One by one, they either design experiments according to their own ideas and use their conclusions, or they come to conclusions halfway through the process, which is full of mistakes and omissions. ”

The so-called spider hearing on the legs, is an experimental joke that should not be true, like a fable. It is said that in order to prove that the spider's hearing organ is on the leg, a magician did an experiment, first put the spider on the experimental table, and made a loud noise at the spider, and the spider was scared away. Then he took out another identical spider, cut off all the spider's legs, and made a noise at the spider, and the spider did not move.

So the magician published a paper proving that the spider's auditory organ was on the leg.

It's a joke, of course, the spider's legs are cut off, and of course it can't run.

Jia Yi has also heard of this story, which is supposed to be a joke, and many teachers will use this story as an explanation before teaching their students to do experiments and write papers.

It's just that Jiayi seems to have some impressions, and he did read a kind of popular science article in his previous life, spiders can use the leg hair on their legs to hear sounds, just like snakes can use their tongues to see things, or infrared vision.

Kaichi wondered if there was a chance to prove that spiders use their legs to hear sounds, which must be interesting to think about.

Fergus carefully flipped through Jiayi's papers and experimental records again, the mage is very strong mental power, and he read it very quickly, and it didn't take long to finish it.

He said: "You are a very good student, so young, you have not studied in the college system, you can have such rigorous thinking ability and hands-on ability, it is indeed very rare." ”

Fergus lamented not how important Jiayi's discovery was, but because of the experimental method represented by Jiayi's experimental records. Sonic magic is nothing special in magic, and "Banshee's Howl" is not a low-level spell, and it has both mental and physical damage.

Although the results of Kaichi's experiment intrigued him, it was the first time that someone had discovered a direction such as acoustic detection. However, this is not as happy as their joy at discovering Jiayi's way of thinking, which means that Jiayi will have more opportunities to discover in the future. For a good mage, a chance gain is far less important than having the ability to make continuous discoveries.

"Yes, yes, I didn't expect you to have such a level Jiayi, although your experiment is simple, but the logic is thorough, the reasoning is rigorous, and it is simply full of beauty. Fergus was the first to say to Jiayi.

Jia Yi smiled shyly, as if he was a little embarrassed.

"Your conclusion is not outstanding, but the experimental process does show the level of an excellent mage. However, it would be nice if you could find something like the last time there was friction. Although this conclusion has led to a detection spell, as long as you know the principle, it is too easy to crack. ”

After Orlando finished speaking, a magic shield floated on his body and looked at Kaichi.

This one looks much more advanced than Jiayi's own shield, but it's brighter and the mana fluctuations are stronger. However, it still doesn't seem to be out of the realm of ordinary magic shields. But Jia Yi knew that it couldn't be so simple, and according to reasoning, he could know that if it was just an ordinary magic shield, it would make no sense to show it at this time.

Most magic shields are more or less the same, translucent eggshell-like things, but in fact, depending on the runes and models used to build the shields, they actually have different effects. However, there are actually other shields, such as the Ice Shield, which can cause frostbite if someone approaches, such as the Fire Shield, which can not only cause burn damage to those who approach, but also explode and blow up those who approach, but these shields are not as good as simple magic shields.

Kaichi took a closer look, and finally discovered the mystery, Orlando's spell shield is layered, two layers before and after, the outer layer looks a little illusory, the back layer seems to be different from the front one, and the rest can't see anything.

"Teacher, this shield of yours has two layers, is there any difference in the middle?" asked Jiayi.

"Experiment with that probe array of yours. ”

When Jia Yi heard this, he hurriedly picked up his own detection array disk, which had already been taken out when he had just given the data to Orlando and them, but they attached more importance to the data, or more to Jia Yi's experimental process, and did not pay much attention to the effect of the array disk.

Jia Yi aimed at Orlando with the array disk, in fact, the array plate did not aim at all, but in order to reflect his solemnity, Jia Yi told Orlando that they were ready, of course, they may also think that they were playing shou qiang.

Jiayi activates the array disk, and a ripple invisible to the naked eye fluctuates towards Jiayi, and after hitting the obstacle, he immediately returns, and then on the array disk, the three-dimensional holographic display area will display a point, and if it is a large area, a straight line will be displayed.

Looking at the area displayed on the array disk in front of you, all the objects displayed are dense, because the screen is too small, and Jiayi's algorithm is not good enough, and the size of the object cannot be confirmed very clearly, and the interference is also very large. Kaichi compared the objects displayed on the array disk, and then compared them with the objects in front of him.

He quickly realized that something was wrong, there was no point that represented his teacher, and the part behind him was also blurred, and his teacher was ignored, to be precise, the sound waves should have been absorbed. Because the wave has a diffraction function, although Orlando absorbs the wave, it will not cause the wave to not come behind him. It's like if you stand behind a fence and you can't hear the sound, even the volume of the sound doesn't change much, but if it's in a closed room, there will be a noticeable difference in the volume of the sound.

"Teacher, did you absorb the sound waves?" said to Orlando about his observations.

"That's right! It's a small application of shields, you just need to add a vacuum layer between the two layers of shields, so that the sound can't be transmitted. After all, there are still some sonic attack magic, and they can directly attack the inside of the human body, and it is difficult to defend with ordinary methods, so for this kind of magic, defense methods have been studied for a long time. ”

Speaking of this, Orlando paused, observed Kaichi's expression, and continued: "Since the principle of sound waves was discovered, the threat of sonic spells has been greatly reduced, and the undead banshee's signature spell 'Banshee's Howl' would have been almost abolished if it hadn't been for mental damage.

"I've also improved this shield to reduce the ability of the outer shield to reflect sound waves, otherwise the outer shield will also reflect your sound waves. This is a temporary improvement, not perfect, if it is improved a little more, it will be even more perfect, because of the diffraction of the wave, nothing will be shown in your array. ”

After Orlando finished speaking, he quietly looked at Jiayi, wanting to see how Jiayi reacted.

Kaichi had expected this, but he still underestimated the mage's acumen, and he didn't expect Orlando to immediately come up with a solution, he thought they would study it for a while before they came up with a solution.
