I want to be happy

Today I will tell you something interesting. After Sha Ling said, his fingers were under the strings, and a series of lively syllables jumped out, creating circles of staggered or parallel curvilinear ripples.

The sound of the piano is crisp and cheerful, exuding a lively atmosphere, like a bird with the most beautiful singing voice, very beautiful.

Suddenly, all the birds hiding in the forest for the night woke up and flew high. From the most common sparrows and magpies to many unknown birds, they all appeared out of nowhere and flew away. In the sky above Shaling, various cheerful birdsongs of "chirping" and "dizzling" gathered together, making a quiet night very lively. They seemed to have a consensus, forming a big circle around the Sha Ling flew above her head.

Once Zhao Wang knew about Sha Ling's abilities, he couldn't help being dumbfounded.

Sha Ling's hands are very measured, and the melody spreads only around Sha's house, without going out of the inner circle, so it won't attract the attention of others.If it weren't for this, the number of birds attracted would never stop there.

"Hundred birds chasing the phoenix?" Sha Hanping blurted out.

"Haha, you can say so." Sha Ling smiled lightly. This song is aimed at birds. The unique ripples and vibrations it emits can make birds and moths rush over like a flame.

The fingertips slid across the strings, dragging out a series of slides, and then came to a standstill.The birds circled around reluctantly for a long time before slowly dispersing.

Sha Ling has always enjoyed studying the changes and applications of ripples.He doesn't think that all the things he sees have certain ripples and frequencies, which means that ripples are the essence of this world. In his opinion, ripples may be the uniqueness of the essence of this world displayed from a certain angle. On the one hand, the relationship with the essence is the exterior and interior of each other, and the change of the appearance sometimes triggers a series of chain reactions correspondingly, so that other manifestations of such things also change.Just like the sound, he changed the ripple and frequency of the sound, and the harmless sound became a murderous weapon.

A little bit of mutation will lead to ever-changing effects, and the incidental effects are used in the mundane world.There are countless ways to easily control the living world, control life and death, and turn the world upside down. Only Sha Ling's indifferent personality can laugh it off and don't care.

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

The tired bird returned to the forest, Sha Hanping and Ding Rufen, who knew that Sha Ling's performance tonight had come to an end, left the seat and went back to the room to rest.Zhao Wang, Lu Rui and Wu Gu chatted for a long time while enjoying the evening breeze, and then dispersed.

Sha Ling held her chin, staring at the dark night sky in a daze.

Infrasound is weakly attenuating energy.The frequency is extremely low and the transmission range is very wide.The infrasound waves caused by a tsunami may circle the earth several times.

Sha Ling has roughly mastered the method of controlling the distance of infrasound waves through countless attempts and explorations.So, just like the ripples of mobile phone and TV signals that can go over mountains and mountains, why can't infrasound waves be used for communication or transmission of information?

Beyond the range that ordinary people can hear, it cannot be captured by ordinary machinery and equipment, let alone translated. If infrasound communication is feasible.It will be the only longest and most confidential communication tool that the Sha family can use.

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

It's a pity that Sha's father, Sha's mother and others are still low in practice, and they can't understand and realize the existence of ripples like him.

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

Although it's not perfect, it's beneficial after all. Every time he goes out to practice, he doesn't like to bring his mobile phone with him. It makes him feel anxious and restrained, but if there is something urgent at home, he can't take care of it.

With the infrasonic communication method, as long as the contact method is determined in advance, and different types of sound waves are used to express different meanings, in an emergency, he can get the news as quickly as possible. No matter where he is on the earth, the infrasonic wave can reach , truly global communication.

As for the generation of these signals, he only needs to research them out, teach them to Zhao Wangsha's father and others, and let them practice proficiently.

Stretching out his hand and snapping his fingers, a smile flashed in Sha Ling's eyes: Is this an alternative voice transmission?

The next day, when Sha Ling shared his idea, everyone in the Samana 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: "You are currently low in cultivation, so you can't receive it like me, and can only be used as a signal in an emergency. I think, should I teach you a simple method first?" A fixed communication method that can be used in times of crisis."

Zhao Wang pondered for a while, and said: "Master, you have practiced with the sound of the zither for a few days, so we can also play the guzheng to disperse the signal, but the guzheng is big, and it is impossible for us to take it with us when we go out. Can you consider replacing it with other light and small instruments? Well, it’s best if the instruments can resonate, so that if one person calls the police, everyone in the door can receive it.”

"Well, what Xiao Zhao said is very reasonable, or should we change to Piccolo?" Sha Hanping suggested.

"If everyone has a unique signal, then we can know who is in danger." Wu Gu thought for a while and added.

Several people brainstormed and put forward many useful suggestions.

Since Qianli Audio can only do the simplest function at present, don't complicate it, it is limited to sending out distress signals, each person has a representative frequency, and other people's can resonate.

To send out a distress signal, the simplest method should be used. It is best to send out a signal as soon as you enter the spiritual energy, so you can make a contact.

Each person's representative sound wave, frequency and intensity are reduced to a very small value, the ripple within this value can lead to another resonance, and different frequencies lead to different vibrations, thus solving the problem of signal identification.

If the thousand-mile microphone is successful, it can be regarded as a relatively low-level magic weapon, right?Sha Ling thought to himself, the idea is well thought out, it sounds simple, but all attempts have to be made from scratch, what material should be used to induce a fixed infrasound wave, to withstand the use of spiritual energy many times, 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 a headache.
