Chapter 226 Success, Echo Location Map

The muscle oscillation method is a oscillation method of forming body muscles by specific breathing and action.

In the half a year of Han Yi's practice, he had to practice for almost five hours every day.

A lot of practice made Han Yi find that after resonance through the chest cavity, the sound of the explosion would be stronger and more destructive.

"Wow~!!"

Taking a deep breath, Han Yi controlled her chest and began to vibrate fiercely.

"Ha~~~!"

Unlike the sonophone explosion in the past, Han Yi's voice is extremely low and slow.

Although it can still be heard, the sound is almost inaudible.

Control, continuous control.

Han Yi gradually reduced the vibration of his chest, while his throat was only spitting out the vibrating air.

The sound disappeared.

Seeing Han Yi's behavior, there was a wave on the metal watch.

Surprised, extremely surprised.

You should know that the so-called ultrasound is just a matter of words.

In fact, he didn't expect much.

After all, it is almost impossible for humans to emit ultrasound.

At least it is impossible at this stage. After all, Han Yi's body is too weak to meet the requirements of ultrasound at all.

However, just now.

The evil but clear detection of ultrasound, low-frequency ultrasound.

At this time, Han Yi's sound produced through chest resonance is about 15HZ, which is within the range that human beings can't hear.

However, its evil can be heard clearly.

"This boy may really be able to collect all 108 cores."

On the surface, evil recognizes South Korea, but in fact it still has reservations.

Although Han Yi successfully melted the core left by his master, it does not mean that he may surpass his master.

And once he can't surpass his master, the core will be taken away by his master's enemies sooner or later.

"Well, the master's enemy has come to the earth for a long time, and this boy is just a hunter. It's really worried."

"But fortunately, that man didn't come, otherwise you wouldn't have a chance at all, but how long can you hide it?"

"In a word, you must find the water of energy here, otherwise even if you find the relics of the core of the collection, this boy will not have the strength to seize it."

******

Of course, Han Yi, who is studying ultrasound at this moment, doesn't know the evil idea. What he has to do now is to keep experimenting.

Through the experiment just now, a smile appeared on his face.

"Evil, is that sound just now ultrasonic?"

Although the voice was extremely low and almost inaudible, it still did not escape Han Yi's ears.

After all, it is not too difficult to concentrate and hear the sound from your own body.

He praised Han Yi without hesitation and said evilly, "Yes, very good. However, it is a low frequency. This kind of ultrasonic penetration is too small to be enough.

"Is that right?" Nodding, Han Yi didn't say anything.

"Wow!"

Take a deep breath again. The low frequency is easy to solve, and the high frequency is not necessarily true.

So he has to keep experimenting.

"~~~~!"

No, it's not enough.

"~~~~!"

is not enough, but it is still not enough.

"Hum~~~!"

Well, it's beyond 20HZ, and I can hear it clearly.

"Hum~~~!"

The voice is gradually getting louder, but Han Yi is also getting deeper and deeper.

Through continuous testing, Han Yi's voice quickly reached the height of 10,000HZ.

"Wow, huh."

Han Yi, who was sweating profusely, stopped.

I'm too tired.

Although it is just a simple resonance chest cavity, it can be pronounced.

But in fact, this practice is several times more tiring than previous training.

It was only an hour, and Han Yi was exhausted.

Stopped the idea of continuing to speak, and Han Yi sat cross-legged. He had to recover his physical strength, otherwise if it goes on like this, he will be exhausted before the water of energy is found.

Han Yi rested cross-legged, and the evil also took advantage of this period to sort out the information of Han Yi's voice and turned it into a visual image.

Suddenly, the metal watch emitted a faint light, and the evil face said with incomparable surprise, "Is this 'spirit'?"

"How could this boy activate the spirit?"

Han Yi, who closed his eyes, ran the spirit in Dantian and quickly surrounded his body.

The core is driven by the spirit, and a stream of energy quickly enters Han Yi's body.

In less than half an hour, Han Yi's physical strength returned to a perfect state again.

Standing up, Han Yi exhaled softly.

He opened his mouth and sucked hard.

"Wow~!"

He began to shake his chest to the maximum extent.

"Hum~~~~!"

It seems that it has reached the limit. Han Yi's physical recovery, the sound made this time is still about 10,000HZ, and there is no change.

"Hmm?" He frowned, and a solemn look appeared on Han Yi's face.

He took a breath again, and Han Yi resonated again.

Failed...!

Failed again...!

10000HZ seems to be the limit of Hanyi. No matter how hard he tries, he can't expand the resonance again.

The continuous highest resonance made Han Yi tired quickly.

There was a wry smile on his face. Han Yi said, "What should I do? Evil, I can't raise the sound by more than 10,000HZ at all.

I have been watching Han Yi's voice silently. Hearing Han Yi's question, Evil immediately said, "Since resonance can't be done alone, why don't you use repeated resonance?"

Han Yi was stunned and said puzzled, "Repeated resonance?"

"That is, high-frequency vibration, but it doesn't release the sound, so that it still stays in your chest."

"Then so, resonate repeatedly."

"Is this possible?" There was a trace of surprise on Han Yi's face, and he was a little uncertain.

The evil smiled and said, "Don't you know when you try it?"

nodded. Since there is no other way, Han Yi can only do so.

"Wow~!"

Taking a deep breath again, Han Yi closed his mouth and his chest resonated again.

This time, Han Yi found that due to the closure of his mouth, the resonance frequency increased very quickly this time.

It reached a height of 8000HZ almost in an instant.

12000HZ, 13000HZ, 14000HZ...

The repeated resonance made the audio in Han Yi's chest quickly reach an unprecedented height of 18000HZ.

"It's done."

There was a trace of joy on his face. Once again, Han Yi was about to open his mouth and send out the first ultrasound in his life.

Suddenly, a trace of pain appeared on his face.

The turbulent chest suddenly stopped.

"Puff!"

With a mouthful of blood spitting out, Han Yi's face turned a little pale, obviously suffering from internal injury.

"What's going on? Why am I hurt?" With a puzzled look on his face, Han Yi looked down at the evil.

"Extreme." Evil explained, "Your body has reached its limit to withstand resonance."

"Oh, I forgot to remind you just now."

"Although your body is strong enough, if you want a resonance of a million times per second, it is still far beyond the limit."

"What's more, the requirement for high-frequency ultrasound is more than two million."

"So just now, you were shocked by the sound generated in your body."

Listening to the evil explanation, Han Yi was stunned.

"What should I do?"

"It doesn't matter. Although the shock hurt you just now, it still came out."

There is a trace of admiration in the evil tone.

The evil words immediately surprised Han Yi and said, "It's done?"

"Of course."

Squeak~!

A huge map about 100 meters wide appeared in front of Han Yi.

"Ectolocation map, in your position, within five kilometers in diameter, everything."

His eyes lit up, and Han Yi's face suddenly showed excitement.

"Huh? This map...?"

Han Yi's face suddenly showed extreme shock, and he looked at the map shown by evil in disbelief.

Second update, ask for tickets, collect...!
