"How did you know?"

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

Yan Yi pulled off the instrument on the table, and took out two metal badges from it - Le Yu wanted to slap his head hard, but the stealing skills were not at home. He even forgot the old routine of dark under the lights!

In the memories of Jing Zhengwei and Yin Yinyin, I don't know how many nobles have deliberately hidden good things in conspicuous places, and they didn't realize this routine at first. But they didn't miss any good things. After all, the two of them are the masters of killing people for food. In the face of the death crisis, the frightened nobles will shake out almost everything. No matter how tightly they are hidden, they will eventually become The trophy of Jyn and the White-haired Assassin.

Maybe it's because Jing Zhengwei and Yin Yinyin are both used to "pressing 'F' to extract a confession" and never follow the technical route, so although Le Yu faintly felt that the instruments on the table were a bit 'big', they didn't realize that it was the best. The storage box, I missed it.

I saw Yan Yi touched the two metal badges and said, "This is a communication tool that we have researched, tentatively called 'Xinxiangji'. When the sun is bright, the longest communication range is five miles, and when it is cloudy It's only two miles away, and the night will be reduced to less than 100 feet. Each use needs to be placed in the sun for three hours to charge, and each use can communicate for up to ten minutes. The quality of communication depends on the distance. When using, you must put your lips close to the badge and activate it. The way to do this is to tap the surface hard so that the bond will start to work.”

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

"Very nice gadget." Lou Yinhai helped his sunglasses, nodded and said, "Okay, ignore this boring topic, Mr. Yan, let's continue to talk about modulation and demodulation of radio signals..."

"Mr. Yan, how many pairs of this kind of thing have you made?" Shang Lingyi asked: "I mean, if this kind of product can be mass-produced, it will definitely cause harm to Yanjing... no, to Quan Huiyao. Indelible impact."

"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, whispering to himself in a low voice that could be heard by everyone in the research room: "I know Letting the smell of copper contaminate academia is the result..."

Yan Yi glanced at Shang Lingyi, tapped her jade finger lightly on the table, glanced at the cabinet, rolled her eyes, and said, "We made five pairs in our laboratory, and the first two pairs were scrapped due to excessive testing. That's the pair we've kept for testing...but it's completely unusable for mass production."

"Xinxiangji is not so much a product researched by our radio team, but rather a creation of Yaoshi Alchemy. Compared with the highest crystallization of Yaoshi alchemy, Shenbing, a mere radio communication function is too trivial. We still have many difficulties to overcome before we can actually use the radio communication tool, and we need many theories to calculate, but with the help of Yaoshi alchemy, we can use our mental power to directly reach the final step, and then put the functions we want into the In the Yaoshi creation..."

Yan Yi put the metal badge back into the instrument, and walked around while talking: "It's not so much a product that we made, it's better to say that this is a toy made by Yaoshi alchemy with a lot of money... Even ignoring labor costs, the cost of each pair of heart-to-heart is more than twenty gold dollars."

Shang Lingyi was startled: "So expensive?"

"Meteorite pyroxite is used in it?" Lou Yinhai asked a question in a positive tone.

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

This meteorite pyroxite is the main material of the Eight Illusionary Weapons.

Unlike when he was ignorant and despised by Yin Yin Yin in the past, Le Yu also collected a lot of information about the magic weapon during his tenure as President Jing Zhengwei. Although it is rarely circulated at the bottom, there have always been poems in rich and noble families. According to the book, when Le Yu went to extort Wang Hai Gong's mansion, in addition to Bai De Huyan Siluo, the fiancée he had never met until his death, he also obtained a lot of 'Bright Secret' books.

In this world, gold, silver, copper and iron can only be regarded as the top ore, and Yaoshi is the foundation of all things. On the Yaoshi, there are two other ores, one is the meteorite pyroxenite, the main material of the legendary weapon, but the meteorite pyroxenite is actually an artificial creation in the internal records of the four guards of Huiyao, so let's not mention it for the time being; Another large ore is meteorite pyroclastic ore.

In fact, it is also a meteorite, but not all meteorites are meteorite pyroclastic minerals, at least the meteorites that have been roasted by the sun and transformed into shinning stones directly in space can be counted.

If the 'received amount of sunlight radiation' is used to judge, the ordinary shinite is 1, and the meteorite pyroclastic is at least 100, but the rarity of the meteorite pyroclastic is at least 10,000 - the price of this stuff is calculated by grams , even priceless.

But yaoshi is the best carrier of spiritual power. If ordinary yaoshi can only let your spiritual power play minesweeper, then meteorite pyroxite can let you play Monster Hunter World Icefield directly - the latter allows you to directly own The ability to distort reality.

As Yan Yi said, if they were to be a radio communication tool, they would still have many unsolved problems. But after using the meteorite pyroxite, they directly 'imported' the function of radio communication, and then the metal badge 'read' their wishes and 'generated' this function.

'I thought this would work~lightnovelpub.net~ and then it really did.

It is conceivable how much the meteorite pyroxite is in short supply and how expensive. That pair of metal badges cost twenty gold dollars, which is no exaggeration at all.

"Then there are still two pairs of heart-to-heart, where are they now?" Shang Lingyi asked the question that Le Yu wanted to know: "If I can, I plan to buy a pair to bring back to the clan elders to see, and I'm sure it can also make They increase the amount of investment..."

"One pair was taken away by Principal Cha, and he took it for nothing. After all, he also helped to provide the meteorite pyroxite." When he said this, Yan Yi also had a black line on his face: "The other pair was sold. went."

"Who did you sell it to?" Shang Lingyi's tone was quite eager, but she quickly returned: "I can discuss with the buyer, 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 came to me wearing a mask and a cape, and spoke directly with Aiki tactics, saying that it was introduced by Principal Cha Huan, but I don't think it was... But if it was the information leaked from Principal Cha Huan, I would Believe."

"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 didn't speak, but Shang Lingyi knew her attitude and immediately said, "Can I see the mutual bond?"

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

Lou Yinhai, who had been shaking his legs impatiently after watching Shang Lingyi tinkering with metal badges in the past, finally raised his spirits: "Our time is very precious and should not be wasted on boring social interactions. Mr. Yan, I think the real meaning of modulation is Move the spectrum of the signal to allow the receiver to separate the desired frequency signal, so that the signals of different spectrums will not interfere with each other..."
