"How did you know?"

Hearing Yan Yi's surprised question, Shang Lingyi and Le Yu did not show a surprise expression, but instead frowned slightly.

Yan Yi pulled the instruments on the desktop and took out two metal badges from it - Leyu wanted to slap his head hard. He couldn't steal the technology, but he even forgot about this old trick under the light!

In the memories of Jing Zhengwei and Yin Yin, I have seen many Haogui deliberately hide good things in a very conspicuous place. They did not realize this routine at first. However, they did not miss any good things. After all, the two of them were the ones who killed people as food. Faced with the crisis of death, the Haogui who was scared to pissed almost everything out. Even if they hid it tightly, they would eventually become the spoils of Qin Riye Demon and the white-haired Assassin.

Perhaps because Jing Zhengwei and Yin Yin were both used to "pressing 'F' to force confession and plunder" and never took the technical route. Therefore, although Leyu vaguely felt that the instruments on the desktop were a bit "big", he did not realize that it was an excellent hidden box, and he missed it.

Yan Yi touched two metal badges and said, "This is the communication tool we have developed, temporarily called "Heart Episode". When the sun is bright, the longest communication range is five miles, and when it is cloudy, it will be reduced to within a hundred feet at night. Each use needs to be placed in the sun for three hours to charge, and each use is at most ten minutes to communicate. The quality of the communication depends on the distance. When using it, the lips must be placed close to the badge. The starting method is to hit the surface vigorously, so that the Heart Episode will start working."

"But the sound will definitely be severely distorted, for example..." Yan Yi put a badge on his lips, handed a badge to Shang Lingyi, and then lowered his voice and spoke. The badge in Shang Lingyi's hand came out with a hoarse voice like a machine rubbing.

"A very good gadget." Lou Yinhai held his sunglasses and nodded, "Okay, ignore this boring topic, Teacher Yan, let's continue to talk about the modulation and demodulation of radio signals..."

"Teacher Yan, how many pairs of this kind have you made?" Shang Lingyi asked: "I mean, if this product can be mass-produced in large quantities, it will inevitably have an indelible impact on Yan Jing... no, it will have an indelible impact on Quan Huiyao."

"Very good, very good, it seems that what you are talking about is more important." Lou Yinhai spread his hands and took a step back, lowered his voice and said to himself, but it could be heard by everyone in the laboratory: "I knew that this is the result of letting the smell of copper pollute academics..."

Yan Yi glanced at Shang Lingyi, gently tapped the table with her jade fingers, glanced at the cabinet, turned her eyes and said, "We made five pairs in the laboratory, and the first two pairs were directly scrapped due to overtesting. These pairs are what we kept for testing... but they cannot be used for mass production at all."

"The Heart-Eye Mechanism is not so much a product developed by our radio group, but rather a creation of the alchemy of Yaoshi. Compared with the highest crystallization of the alchemy of Yaoshi, the divine weapon, a radio communication function is too insignificant. We still have many difficulties to overcome and require many theories to calculate, but with the help of the alchemy of Yaoshi, we can use our mental power to directly reach the last step, and then stuff the function we hope into the alchemy of Yaoshi..."

Yan Yi put the metal badge back into the instrument and walked around while talking: "It's not so much that this is the product we made, but rather that this is the toy made by Yaoshi Alchemy for a large price... Even if we ignore the labor cost, the cost of each pair of heart-to-heart seal is more than twenty gold yuan."

Shang Lingyi was stunned: "So expensive?"

"Is the meteorite shaving mine used?" Lou Yinhai said a question in a affirmative tone.

As soon as these words came out, Leyu also understood why this thing was so expensive.

This meteorite shading mine is the main material of the Eight Illusion Divine Weapons.

Unlike when he was ignorant and despised by Yin Yinyin, Leyu also collected a lot of information about the magic weapon during his tenure as President Jing Zhengwei. Although it was rarely circulated at the bottom, there have always been records of poetry and books in the wealthy family. When Leyu went to blackmail Wang Haigong Mansion, in addition to Bai Dehuyan Siluo, who had never met his fiancee until his death, he also obtained a lot of classics of "Huiyao Secret".

In this world, gold, silver, copper and iron can only be regarded as the addition of the heads, and the rays are the foundation of all things. There are two major ores above the rays, one is the meteorite pyrostone, the main material of the legendary magic weapon. However, in the records within the four guards of Huiyao, the meteorite pyrostone, which is actually an artificial creature, so I won't mention it for now; and the other large ore is the meteorite pyrostone.

In fact, it is meteorites, but not all meteorites are meteorite diaphragm mines. At least they have been roasted by the sun and can only be considered as meteorites that have directly transformed into radiant stones in space.

If we use the 'acceptance of sunlight radiation' to judge, ordinary rays are 1, and meteorite radiant ore is at least 100, but the rarity of meteorite radiant ore is at least 10,000 - the price of this thing is calculated in grams, and it is even priceless.

But as the best carrier of mental power, if ordinary magic stones can only allow your mental power to sweep mines, the meteorite radius mine allows you to directly play the Monster Hunter World Icefield - the latter allows you to directly have the ability to distort reality.

As Yan Yi said, if they were to make a radio communication tool seriously, they would still have many unsolved problems. But after using the meteorite shaving mine, they directly "imported" the radio communication function, and then the metal badge "reads" their wishes and "generates" this function.

‘I thought this would work’, and then it really worked.

It is conceivable how in short supply and expensive the meteorite shavings ore is. The cost of the metal badge is twenty gold coins, which is not an exaggeration at all.

"There are two pairs of heart-to-heart relationships. Where are they now?" Shang Lingyi asked the question Leyu wanted to know: "If possible, I plan to buy a pair and take it back for the clan elders to see. I believe they can increase their investment quota..."

"A pair was taken away by Principal Tea, and it was taken out for nothing. After all, he helped to provide the meteorite shavings mine." When he said this, Yan Yi also looked dark: "And the other pair was sold."

"Who did you sell it to?" Shang Lingyi's tone was quite anxious, but she quickly returned: "I can go and discuss it with the purchaser, maybe the other party is willing to sell it to me."

Yan Yi turned her back to the cabinet and shook her head: "I don't know."

"have no idea?"

"The other party found me wearing a mask and a cloak, and directly spoke out with the Aiqi tactics, saying that it was introduced by Principal Cha Huan, but I think it was definitely not... But if it was the information leaked from Principal Cha Huan, I would believe it."

"Then you still sell it?" Shang Lingyi asked.

"Because the other party offered a price that I couldn't refuse."

“What price?”

Yan Yi smiled and said nothing. Shang Lingyi knew her attitude and immediately said, "Can I see the connection between my heart?"

"No problem, as long as you don't take it out, you can test it casually in the laboratory."
