Chapter 391

"How did you know?"

Hearing Yan Yi's surprised rhetorical question, Shang Lingyi and Yue Yu did not show a surprised expression, but frowned slightly at the same time.

Yan Yi opened the instrument on the table and took out two metal badges from it. Yue Yu wanted to pat himself on the head. He didn't know how to steal. He even forgot the old routine of black under the light!

In the memory of Jing Zhengwei and Yin Yinyin, I don't know how many dignitaries have deliberately hidden good things in a very conspicuous place. They didn't realize this routine at the beginning. However, they didn't miss anything good. After all, those two are murderers. In the face of the death crisis, the pee scaring dignitaries almost shake out everything. Even if they hide more tightly, they will eventually become the booty of Qin day night demons and white haired assassins.

Maybe it's because Jing Zhengwei and Yin Yinyin are used to "extorting confessions by pressing 'f' and never take the technical route. Therefore, although Yue Yu vaguely feels that the instrument on the table is a little" big ", he doesn't realize that it is an excellent collection box. He was stunned and missed it.

Yan Yi touched two metal badges and said: "This is a communication tool we have developed. It is temporarily called" heart to heart printing ". When the sun is bright, the longest communication range is five miles, when it is cloudy, it is only two miles, and at night it will be reduced to less than 100 feet. Each use needs to be placed in the sun for three hours, and the maximum communication time is 10 minutes. The communication quality depends on the distance. When using it, you must keep your lips close to the emblem Zhang, the starting method is to tap the surface vigorously, so that the heart seal will begin to work. "

"But the voice must be seriously distorted, for example..." Yan Yi put a badge on her lips, handed a badge to Shang Lingyi, and then spoke in a low voice. The badge in Shang Lingyi's hand sounded like a hoarse sound of machine friction.

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

"Miss Yan, how many pairs of such things have you made?" Shang Lingyi asked, "I mean, if this product can be mass produced, it will certainly have an indelible impact on Yanjing... No, on Quan Huiyao."

"Very good, very good. It seems that what you are talking about is more important." Lou Yinhai stood up and stepped back. He lowered his voice to himself, but everyone in the research room could hear him: "I knew that this was the result of letting the copper smell pollute the academic..."

Yan Yi glanced at Shang Lingyi. Yu Zhi gently clicked on the table, glanced at the cabinet, turned her eyes and said, "we made five pairs in the research room, and the first two pairs were directly scrapped because of over testing. These pairs are what we keep for testing... But they can't be used for mass production."

"Xinxiangyin is not so much a product developed by our radio team as a creation of Yaoshi alchemy. Compared with the highest crystallization of Yaoshi alchemy - Divine soldiers, a mere radio communication function is too insignificant. We still have many difficulties to overcome and need many theories to calculate from the truly available radio communication tools, But with the aid of Yaoshi alchemy, we can use our spiritual power to directly reach the last step, and then insert our desired function into Yaoshi creation... "

Yan Yi put the metal badge back into the instrument and walked around while talking: "it's not so much the product we made, as it's a toy made at a high price under Yaoshi alchemy... Even if the labor cost is ignored, the cost of each pair of heart seals exceeds 20 gold dollars."

Shang Lingyi was stunned: "so expensive?"

"Meteorite pyroclastic ore is used in it?" Lou Yinhai said a question in a positive tone.

Once this was said, Yue Yu also understood why this thing was so expensive.

This meteorite pyroclast mine is the main material of the eight magic magic soldiers.

Unlike when she was ignorant and despised by Yin Yin Yin in the past, Yue Yu also collected a lot of information about divine soldiers when she became president of Jing Zhengwei. Although it was rarely spread at the bottom, there have always been poetry records in the rich and noble family. When Yue Yu blackmailed Wanghai Duke's residence, she got a lot of "glorious secrets" in addition to Bai dehuyan siruo, a fiancee who had never touched her until she died ’Ancient books.

Gold, silver, copper and iron can only be regarded as additions to the world's minerals, and Yaoshi is the foundation of all things. On Yaoshi, there are two major minerals. One is meteorite pyroxene, which is the main material of the legendary Jue Shenbing. However, according to the internal records of Huiyao four guards, meteorite pyroxene is actually an artificial creation, not to mention for the time being; the other is meteorite pyroxene.

In fact, they are meteorites, but not all meteorites are meteorite pyroxenes. At least meteorites that have been baked by the sun and directly transformed into flares in space can be regarded as meteorites.

If we use the "amount of sunlight radiation received" to judge, the ordinary Yaoshi is 1, and the meteorite pyroxene is at least 100. However, the rarity of meteorite pyroxene is at least 10000. The price of this thing is calculated in grams, and even there is no market.

However, Yaoshi is the best carrier of spiritual power. If ordinary Yaoshi can only let your spiritual power play minesweeping, meteorite pyroclastic ore can let you directly play with the ice sheet of monster hunter world - the latter can directly give you the ability to distort reality.

As Yan Yi said, if they are serious about making a radio communication tool, they still have many unsolved problems. However, after using meteorite pyroxene, they directly "imported" the function of radio communication, and then the metal badge "read" their wishes and "produced" this function.

"I thought it would work," and then it really did.

It can be imagined that meteorite pyroxene is in short supply and expensive. The cost of that pair of metal badges is twenty gold dollars. It's no exaggeration at all.

"There are still two pairs of heart to heart seals. Where are they now?" Shang Lingyi asked the question Yue Yu wanted to know: "if I can, I'm going to buy a pair and take it back to the elders, which must also enable them to increase their investment..."

"One pair was taken away by the tea headmaster and took it directly for nothing. After all, he helped to provide meteorite pyroclast ore." when talking about this, Yan Yi also looked black: "and the other pair was sold."

"Who did you sell it to?" Shang Lingyi's tone was quite urgent, but she soon came back: "I can go to the buyer to discuss it. 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."

"Don't know?"

"The other party came to me wearing a mask and cloak, and made a voice directly with the Qi closing method. He said it was introduced by headmaster chahuan, but I don't think it was... But if it was the information leaked from headmaster chahuan, I would believe it."

"Do you still sell?" asked Shang Lingyi.

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

"What price?"

Yan Yi smiled and didn't speak. Shang Lingyi knew her attitude and immediately said, "can I see the heart seal?"

"No problem. As long as you don't take it out, you can test it in the research room."

Looking at Shang Lingyi's metal badge, Lou Yinhai, who has been shaking his legs, finally raised his spirit: "our time is very precious and should not be wasted on boring social activities. Mr. Yan, I think the essence of modulation is to move the spectrum of the signal, let the receiver separate the required frequency signals, and prevent signals of different spectrum from interfering with each other..."
