I'm going to listen to you today. "Sha Ling said, fingers on the strings▋|I'll listen to you an interesting one today.

"Sha Ling said, fingers on the strings▋|I'll listen to you an interesting one today. "Sha Ling said, fingers on the strings▋|I'll listen to you an interesting one today. Sha Ling said, his fingers under the strings, a series of live syllables jumped out, bringing up a circle of staggered or parallel curve ripples.

The sound of the piano is crisp and cheerful, revealing a smart breath, like a bird with the most beautiful voice singing, which is very beautiful.

From the most ordinary sparrows, magpies, to many unknown birds, all came out of nowhere, and flew over Sha Ling, "chirping", "chirping", "chirping" all kinds of cheerful birdsong gathered together, disturbing a quiet night into a lively atmosphere, they seemed to have a consensus, forming a big circle, flying around Sha Ling's head.

No matter how Zhao Wang and the others knew Lu Dao Shaling's ability, they couldn't help but be stunned.

Sha Ling is very measured in his hands, and the scope of melody dissemination is only limited to the vicinity of Sha's house, and there is no *** out of the inner circle, which will not attract the attention of others. If it weren't for that, the number of birds attracted would never have been greater.

"A hundred birds and a phoenix?" Sha Hanping blurted out.

"Ha Lu Ha, you can also say it. Sha Ling smiled faintly, this song is aimed at birds, and the unique ripples and vibrations it emits can make bird moths rush over like fire.

Fingertips run over the strings, dragging a string of glissandos before coming to a standstill. The birds lingered for a long time before they slowly dispersed.

The study of the variation and application of ripple has always made Sha Ling tired. He does not think that all the things he currently sees have a certain ripple and frequency, which means that ripples are the essence of this world, and in his opinion, ripples may be a unique aspect of the essence of this world from a certain angle, and the essence is a relationship between the surface and the inside, and the change of the appearance will sometimes correspondingly provoke a series of chain reactions, so that other manifestations of such things will also change. It's like a sound, he changes the ripples and frequencies of the sound, and the harmless sound becomes a murderous weapon.

A little change will cause a kaleidoscopic effect, and the accompanying effect will be used in the mortal world. There are countless kinds of things that can easily control the realm of living beings, control life and death, and turn the world upside down, and only Sha Ling's indifferent character can smile and pass by, and he doesn't care at all.

As far as he is concerned, although he has not really touched the face of the world, he feels and touches with the invisible rules that are more complex and changeable and mysterious than the world world that has been presented in front of him before, which makes him like a child playing on the sea, and he is pleasantly surprised by the different shells that will be washed ashore every time.

The tired bird returned to the forest, and Sha Hanping and Ding Rufen, who knew that Sha Ling's performance was over tonight, first left the table and went back to the house to rest. Zhao Wang, Lu Rui and Wu Gu chatted for a long time in the evening breeze.

Sha Ling held his chin and stared at the dark night sky with concentration.

Infrasonic waves are weakly attenuated energy. The frequency is extremely low and the propagation range is very wide. Infrasound waves caused by a tsunami can circle the Earth several times.

After trying and groping without counting the number of times, Sha Ling has roughly mastered the method of controlling the distance of infrasound. So, just like mobile phones, TV signals, etc., can ripple over mountains and mountains, why can't infrasound waves be used to communicate or transmit information?

It is beyond the scope of what ordinary people can hear, and it cannot be captured by ordinary machines and equipment, let alone translated, if infrasound communication is feasible. It will be the only longest-distance and most confidential communication tool that the Sha family can use.

He just thought of this thought in his heart. The more I think about it, the more feasible it becomes.

It's a pity that Sha Father and Sha Mu and the others are still low in cultivation, and there is no way to understand and discover the existence of ripples like him.

In this way, it can only be a one-sided contact.

Although it's not perfect, after all, it's beneficial, every time he goes out to practice, he always doesn't like to carry his mobile phone, which makes him feel a sense of longing and constraints, but if there is a bit of an emergency at home, he can't take care of it.

With the infrasonic contact method, as long as the contact method is determined in advance, and the sound waves are not planted to express different meanings, in an emergency, he can get the news as soon as possible, no matter which end of the earth he is, it is infrasound that can be achieved, and truly achieve global communication.

And the issuance of these signals only needs to be studied by him and taught to Zhao Wangshafu and others, so that they can practice skillfully.

Stretched out his hand and snapped his fingers, a smile flashed in Sha Ling's eyes: Is this an alternative Qianli Transmission?

The next day, as soon as Sha Ling told him his idea, everyone in Shamen felt that the idea was feasible, and stared at Sha Ling excitedly.

Sha Ling touched his nose and pointed out the problem of the feasibility of this method: "Your cultivation is low now, so you can't receive it like me, and you can only use it as the sender of the signal in an emergency." I wonder if I would like to teach you a simple and fixed way of communication, which can be used in times of crisis. ”

Zhao Wangluo sighed and said: "You have been practicing with the sound of the qin for several days, so can we also diverge signals by playing the guzheng, but the guzheng is large, if we go out, it is impossible to take it with us at any time, maybe we can consider replacing it with other light and small instruments? ”

"Well, what Xiao Zhao said makes a lot of sense, or is it a piccolo?" Sha Hanping proposed.

"If everybody has a unique signal sign, then we can know who is in danger in the road. Wu Gu thought for a moment and added.

Several people brainstormed and put forward a lot of useful suggestions.

Since Qianli Sound can only do the simplest function at present, then don't complicate it, and only limit it to sending a distress signal, each person has a representative frequency, and other people's can resonate.

To send a distress signal, you should also use the simplest method, it is best to send a signal as soon as you inject aura, then make a trigger type.

The frequency and intensity of each person's representative sound wave are reduced to a very small value, and the ripples within this value can cause another resonance, and different frequencies cause different vibrations, thus solving the problem of signal recognition.

Thousands of miles of microphone, if successful, can be regarded as a relatively low-level magic weapon, right? Sha Ling secretly thought, the idea is to think about it, it sounds simple, but all attempts must start from scratch, what material to choose to cause a fixed infrasound, in order to withstand the use of multiple aura, in order to cause resonance......

There are a lot of problems, and there is no experience of the former to learn from, but it makes Sha Ling have a big headache.
