Heaven's Formula

"Ask how to avoid it?"

"The first point, if you are a person who has participated in the imperial examination, the evaluation will be downgraded by default." He held out a finger.

There was an uproar in the crowd!

Staff Officer He seemed to be choking, "Lord Xia, are you serious?"

"Of course." Xia Fan said as a matter of course, "Ideology is also a part of education. Considering that these people's ideas are likely to have formed and they will no longer accept the new system, they are naturally not suitable to be officials of the Bureau. There are enlightened elements in China, so it is reasonable to raise the threshold.”

As the so-called line is wrong, the more knowledge the more reactionary, this is really a wise saying.

Ning Wanjun couldn't help raising the corners of his mouth, all the kings in the world were eager to win over scholars, but he was lucky, not only didn't care about them, but also wanted to push them away.Sure enough, the listener did not act according to common sense at all. In his eyes, I am afraid that nothing is "as it should be".

Xia Fan's unexpected statement relieved her already somewhat heavy heart.

But before everyone looked at her, she returned to her solemn expression, "What about the second point?"

"The second point is the method. If Jinxia City can keep in touch with other places at all times, and the information can be exchanged within half an hour or even less, then it will be more difficult for both temporary officials and reviewers to get rid of Jinxia City. influences."

"Half an hour?" Xu Sanzhong showed a surprised expression, "Even if one person and two horses run wildly on the road, they can't do this."

"If there is such a method, wouldn't it be even more powerful when it comes to marching and fighting?" Others also commented.

"It is indeed prepared for future battles, but I didn't expect the research progress of this technique to be faster than expected." Xia Fan stood up, "If you want to see it, I can prove it now."

……

A quarter of an hour later, he set up the antenna, the receiver and a wooden square engraved with talismans at the entrance of the lobby.

Ning Wanjun fixed her eyes on the piece of wood.

She picked it up, put it in her hand and looked at it carefully for a moment, "Is this...a shock spell?"

"Oh? You can see that?"

"No... I don't understand what is painted on it at all." Ning Wanjun didn't hide it, "I can at least guess one or two about other types of alchemy talismans, and the ones who don't understand at all must be your fiddle. something that came out."

"You guessed right." Xia Fan smiled, "It is indeed a magic weapon, and its function is very simple. It just makes the current fluctuate repeatedly."

After further improving the streamer technique to his unique shock technique, Xia Fan naturally came up with the idea of ​​"magnetism".Electricity and magnetism are a natural pair. There is an electric field around the current, and the change of the electric field will produce a magnetic effect.It can be said that if the shock technique can induce an electric current, it must be able to create a magnetic field. This speculation has been confirmed by a streamer technique that consumes a sharp change in gas consumption - the deflected magnetic needle ten steps away is enough to show that the current released by the streamer technique has the power of electricity. all the basic features.

So Xia Fan put the first target on the radio communication.

Compared with single-purpose items such as Shock Justice and Biped Mecha, radio can be said to be a widely used and subversive invention.It greatly shortens the distance of the world, which in turn equals to greatly expand the area that humans can reach.

Some studies have said that there was an upper limit on the territory of ancient dynasties, and once it exceeded it, it would easily disintegrate. The reason is that it is difficult for government orders to reach every corner under the emperor's rule.Those areas that have not received imperial edicts or oral orders for a year or two or even more than ten years naturally do not take the central court seriously.Once the national power declines, they can easily separate, either to become kings on their own, or to eat back the original dynasty.

This kind of problem is also easy to appear in the new regime - after all, the foundation of the princess is not stable. If Jinxia's connection with the local area can be strengthened, it will undoubtedly greatly alleviate her lack of influence.

Xia Fan originally thought it would take several months, but controlling the fluctuation of the current went smoother than expected.Since leaving Qingshan Town, he has used the streamer technique thousands of times, and the copper wire pendant he consumed can be piled up into a small bag of soil, which makes it possible for him to use the first-level technique in the palm of his hand even without relying on talismans and primers. Pull out an arc that is half an arm long, and the intensity of the display is even more arbitrary.

Unknowingly, his experience and accumulation in the shock technique has been far ahead of his fellow alchemists.

Chapter 215 The First Cry

The essence of wireless communication is to control the frequency of electromagnetic waves.

As long as the current fluctuates, a correspondingly changing magnetic field will be generated. In other words, the first thing Xia Fan has to do is to make the electric energy of the streamer technique change rapidly—or vibrate.

And the detailed control of the technique has already matured in more than a thousand times of repeated performances.

It only took him two days to use the new streamer technique to let out a sharp howl.This "sound" has a very high frequency and cannot be captured by the human ear, but under the electromagnetic background, it is like a raging ripple, centering on Fengyang Villa and spreading out to all around Qiguo in an instant.

Xia Fan witnessed all this through the swinging magnetic needle.

Like the shocking justice, this new technique based on the streamer technique should also have a distinctive name.

He named it "Xunyin", after the second half of a groundbreaking electronic song.

The next step is to make magic tools.

This is also the enlightenment given to him by Mo Yun's celestial motion instrument-Xia Fan never hopes that only he can perform this technique, otherwise he will have to stay at the dispatching station whenever he has nothing to do, and become a part of the communication equipment.In that case, how can there be time to play with the fox demon?

And Mo Yun also spared no effort in teaching the making of magic weapons, almost teaching him to carve the first vibration magic weapon of the sound-sounding technique.

The trick is to condense the qi on the fingertips, and while engraving the talisman, the consciousness is concentrated on the effect you want to express.

The key is the idea.

The clearer the idea, the higher the final yield.

This is also the key difference between carpenters carving sculptures and alchemists carving magic tools.

The talisman chosen by Xia Fan is naturally an oscillating circuit - it is only composed of a power supply, an inductor and a capacitor, representing the most basic resonance principle, after all, no matter how advanced he is, he can't draw it.In addition, the place where the power source should have been was replaced by a streamer talisman. On this artifact, the essence of the two eras has been combined for the first time.

"Okay..." Ning Wanjun put down the magic weapon, and circled around the equipment he prepared several times, "How do you prove that it can...um, send messages over a long distance?"

"Just wait." Xia Fan said calmly, "I have sent Li to the Privy Council Mansion, where she will contact us."

"The Privy Council?" The princess glanced in the direction of Jinxia City, "Shouldn't be able to hear the shouts at this distance. Then... what will I see? Is it a note that appeared out of thin air, or—"

Just when she was halfway through speaking, there was a sudden sizzle sound from the receiver.

Then, Li's familiar voice sounded in front of everyone, "Xia Fan...can you hear me? Hey...this thing should be used in this way, right? In case...hey...you remember to reply me as soon as possible..."

The voice was intermittent and accompanied by obvious noises, but even so, it was indeed Li talking!

This scene made everyone present look shocked!

Xia Fan unhurriedly drove the Xunyin instrument, converted his voice into high-frequency radio waves and emitted it, "I heard your voice."

After a short pause, a voice came from there again, "That's it... that's all right."

When Li's voice fell to the ground, the scene exploded!

"Is this true? Miss Li is now in Jinxia City?"

"It's three or four miles from the villa to the Privy Council!"

"The thing making the sound seems to be this drape—"

"Lord Xia, can only alchemists use it?"

Some couldn't believe it, some looked around for Li, and some asked Xia Fan... All of a sudden, there was an uproar in front of the lobby.

"Okay." Until Princess Guangping spoke, everyone stopped talking, "If I remember correctly, there is a spell in Sunda that can amplify the sound several times, but the distance is extremely limited, and it is impossible to talk back and forth like you. Xia Fan, how did this thing do it?"

In fact, Ning Wanjun was no less shocked than the others at the moment. If only she and Xia Fan were present, she probably couldn't help but stepped forward to ask for a experience.

Now that there are so many people around watching, she could only continue to maintain the dignity of the princess, and asked pretendingly calmly.

"The shock technique can turn sound into an invisible electromagnetic signal. As long as there is suitable equipment, the signal can be restored to sound. This is the basic principle of the sound instrument." Xia Fan explained concisely.

"Electrical... what signal?"

A group of people were stunned after listening to it, obviously it was beyond their comprehension.

Xia Fan didn't intend to go into details, because this is not something that can be explained clearly in one or two sentences.The effect of the spell depends on the consciousness of the caster, which is also the key to allowing the current to oscillate according to his own ideas, thus skipping the two thresholds of wired communication and wireless telegraphy, and directly reaching the target in one step.

Regardless of the shock technique, the receiver is something completely unrelated to alchemy.It was a simplified version of an ore radio, using pyrite as the detection core, which can convert electromagnetic waves into oscillating currents, and through the interaction of copper wire coils and magnets, restore the voice of the speaker.

It cannot be tuned, nor does it have a filter function, which causes continuous noise when transmitting messages, and the sound quality only stays at the level where you can hear what the other party is saying.But for such a thing, it took much longer than researching new alchemy.Just a suitable piece of pyrite made Xia Fan rummage in the blacksmith's shop for several days.

Mineral radios were popular in the streets and alleys of the motherland in the 60s, and parts could even be bought in canteens. Although Xia Fan did not personally experience this era, he did tinker with several collections at home.Even so, it took him a lot of brainpower to piece together a simplified version of the receiver with the materials at hand.

Fortunately, after repeated attempts, the first principle machine finally met his most basic requirements.

"Cough... what I'm asking is not the principle." Ning Wanjun immediately realized that her questioning method was wrong, and then changed the questioning method, "Do you have to be a person who is sensitive to send messages to each other?"

"It is necessary to send a message, but not to receive it. The sound from one sound instrument can be heard by multiple receivers." The biggest advantage of the ore radio is that it is easy to use and does not even need a power supply.

"How far can this sound travel?"

"It's only tens of miles at the moment." Xia Fan made an estimate. After all, the audio instrument and receiver are quite simple, and there is still a lot of room for improvement in the future. question."

In fact, not to mention the Great Enlightenment, even the Six Nations will be shrouded in invisible electromagnetic waves.

"Then... what restrictions does it have?" Ning Wanjun couldn't help but clenched her hands and asked.A magic weapon that can transmit sound for thousands of miles and can be restored at any time is definitely something that the army dreams of.The battlefield situation is changing rapidly, whoever can gain the advantage in intelligence will be able to seize the opportunity!

"Except for those who are sensitive, there are no restrictions."

"It has nothing to do with terrain, weather, day and night?"

"Yes." Xia Fan affirmed, as one of the epoch-making products, how could radio be such an inconvenience?

"I understand." Ning Wanjun raised her head and patted him on the shoulder heavily, "The proposal you mentioned at the meeting before, try to come up with a charter."

Chapter 216 Like a Big Sister

In the evening, Luo You'er received Luo Qingqing who had returned from "listening to the class" at a location near the dock yard in Beicheng District.

This is the place where Mo Yun chose the new machine building bureau to settle. During the battle with Dongsheng Kingdom, the houses around the yard were severely damaged, and the salt cooking yard was abandoned with the fall of the Wang family. These were originally used for the opponent's salt. The warehouse has also become useless.Therefore, during the reconstruction process, the new machine building has become a landmark building in this area.

Although the factory building has only an outline, the teaching and research room used to train assistants has been put into use. It is here that Mo Yun imparts knowledge to the team he has gathered and hone his mechanism manufacturing skills.

"Senior sister, I'm here!" Luo You'er's eyebrows and eyes frowned when she saw Luo Qingqing, and she trotted all the way to his side, "How do you feel? Those elves... If you don't look at their ears, both men and women are very handsome Bar?"

Luo Qingqing couldn't help but raised his forehead and said, "So you paid attention to this? You should know that if I don't get close to a person, I can't see the person's face clearly."

Although she was reminded by her junior sister before going, she was still shocked when she saw a group of "monsters" who were very different from herself sitting in the lobby.

One of the responsibilities of alchemists is to slay demons and demons.

But now, Xia Fan, the Prime Minister of the Jinxia Privy Council, has become the protector of the monster instead.This strong contrast still made her subconsciously feel uncomfortable.

If it wasn't for her psychological expectations, she would have almost recruited Longlin.

But another thought clearly told her that this place was neither Shangyuan, Gyeonggi, nor Luojia, Youzhou.From the moment he disembarked, he should have understood that Jinxia City had a unique set of rules.

People often say that one side supports another side, but she always feels that this city is assimilating towards Xia Fan.

So Luo gently found a back seat and sat down quietly.

This is an afternoon.

The fact is that the demon didn't bother her at all, and she soon immersed herself in the knowledge Mo Yun told, and she still has endless aftertaste to this day.

"Hey, that's my first impression." Luo You'er stuck out her tongue and admitted generously, "As for the wonderful, magical, and concise beauty that Sister Mo Yun often talks about, I really can't experience it. "

"It's not because you waste all your time on trifles, but don't have much time to actually read books."

"No, Senior Sister."

Luo slightly startled, "No?"

Luo You'er walked in front of her with her hands behind her back, "Actually, when you went to the library to explore, I always read in my room. It's just that at that time no matter what... I couldn't catch up with your progress."

Luo Weiwei slowed down unconsciously.

"After coming to Jinxia City, I gradually realized that the gap between people cannot be made up by hard work alone. It is impossible for You'er to catch up with the back of Senior Sister in terms of knowledge, but she also has her own ability. Competent stuff." Luo You'er turned her head and smiled at her, "Look, my job in the secretariat can help you? Now I'm the leader of a team with more than ten people, Xun The technique has also improved a lot, so it should be regarded as catching up with the senior sister a lot in other aspects, right?"

"Sister..."

"I will never be able to do what you want to do, and I don't even dare to think about it. But it doesn't matter, you can do it with confidence, and I will take care of you behind your back——together with the brothers and sisters " Luo You'er pressed her chest and said.

Luo slightly felt a warm current rushing from his heart to his eyes.

In order to maintain her senior sister's image, she stepped forward and patted her on the forehead, raised her eyes and said, "Senior sister is not disabled enough to require you to take care of her. But... thank you for saying so."

Luo You'er pursed her lips, and suddenly changed the subject, "Senior Sister, it's been a few months since I saw you. Did you feel that Xia Fan's appearance changed when you saw him?"

"No." Luo Weiwei said with some doubts, "It's still the same as before, even the speaking style...is similar to when he was in Qingshan Town. I always feel that his character seems to have been finalized a long time ago."

"Oh!" Luo You'er showed a dazed expression, "So, you have come within a foot of him!"

She froze for a moment, then raised the knife in her hand.

"You really... talk a lot!"

"Senior sister, please forgive me!"

The two chased after each other for a while, when Luo You'er suddenly stopped, "By the way, do you want to go say hello to the people you brought?"

"what?"

"When you decided to go to Gyeonggi, you probably didn't plan to come back? Now that you have decided to stay temporarily, maybe you can tell those people that you still haven't left?"

Luo slightly hesitated, "I think it's better to forget it... It's not a bad thing for them to have fewer entanglements with me—"

Before she finished speaking, Luo You'er took her hand, "Anyway, we have to pass through Dongcheng District to go back to our residence, so let's take a look along the way. Not seeing each other for three days is enough for their lives to change."

The second half of the other party's sentence made her somewhat concerned. Can it bring about changes in three days?With a skeptical attitude, Luo Qingqing was led by Luo You'er to the villagers' residence.

At this time, it was time to start a fire and cook, and the smoke rose above every household.While the adults are busy, the children are frolicking in the front yards of the rowhouses, and the whole street looks quite lively.

Just when she was undecided whether to continue approaching, Luo Youer pushed her waist and walked out of the street.

"It's Big Sister!"
