Chapter 225 Ultrasound

"Why did you blow the siren?"

With Tom, five clergy in white rushed over.

"The target appears."

With no expression on his face, the man who killed Pengpeng wiped off the blood on the sword.

Tom was stunned by the other party's words and immediately thought of something.

"You mean Han Yi?"

"Yes."

Looking at the blood stains on the ground, Tom frowned and said, "Did you kill him?"

"No."

"What are these blood stains?"

"He saw Pengpeng, who was being monitored."

"Is that right?" There was no change in his face. Tom continued, "So where is the target?"

"Below here."

Pointing to the place where Han Yi went down, the priest said.

"Slit on the ground?" Looking at the bottomless crack, Tom's face showed surprise.

"What did he do in the seam?"

With a frown, Tom looked at the priest and turned to two of the clergy behind him and said, "You, you. The three of you go down together and see what the target is doing.

"If you find out, kill him immediately."

"Yes, where is Peng Peng's body?" Tom asked when he looked around but didn't find Pengpeng who had been killed.

"I threw it down."

"Hey, why did you throw it away? This is a good opportunity to make a mistake.

Shaking his head helplessly, Tom was a little depressed about these rigid clergy.

"But it doesn't matter. After going down, find Pengpeng's body by the way. If you find it, take the body to the target person."

"Why?"

Obviously, three people can't understand this kind of trouble.

"Peng Peng died on the edge of the ground seam, and the only person who enters the ground seam is the target person."

"If you use this excuse to trouble him, then he must be confused, and it will be much easier to kill him in this way."

After listening to Tom's words, the three of them did not change at all. They nodded and said, "Yes."

"Well, go early and come back early."

After saying that, the three assigned clergy looked at each other and immediately jumped down to the bottom of the ground.

Looking at the three people, there was no change in Tom's face.

"Hum..., Han Yi, can you escape this time?"

"It's worthy of William's personal subordinate. It's really fierce enough."

Looking at the remaining blood on the ground, a strange color flashed in Tom's eyes.

"When can I have such a subordinate?"

"However, the little ghost Pengpeng is dead, and I have to explain it to those little ghosts. It's really troublesome."

Turning his head, Tom said to another person, "Go back and tell the group of little ghosts the news of Pengpeng's death. Well, it is said that suddenly someone attacked and shot down Pengpeng into the crack of the ground, and then Pengpeng's guardian has now chased the other party.

"Yes!"

nodded, and the man left immediately.

Standing on the cracks on the ground and looking down, a smile gradually appeared on Tom's face.

"It's good to stand high and master the feeling of life..."

****

Deep in the seams.

Han Yi, who climbed down the ground seam, followed the evil instructions and came to a position about 500 meters deep below the ground seam.

After evil detection, there is an artificial cave about 100 meters from their right hand side.

Without saying a word, Han Yi immediately climbed to that position.

However, it didn't take long for a while to crawl, and an object fell from the sky.

He frowned, and Han Yi looked at the object doubtfully.

"What is it?"

"It should be a person, but he was killed."

"Just above, I found one of the people you came down."

"Although I can't hear the conversation between the two of them just now, it should not be a gang in terms of clothing."

Note: The clergy belong to special positions in the light heaven, specializing in the defense of the Pope and the divine son who is qualified to become the next pope. The equipment they wear is different from ordinary sacrificial uniforms.

"Probably because I found you going down from here and thought I had found some secret."

"After the boy was killed, the murderer immediately summoned his partners."

"Huh? Three people came down. It's so fast!"

Hearing this, Han Yi's eyes narrowed slightly.

"It's just that you found that I came down from here and killed people in order to avoid the spread of this news?"

"Evil, where did they come down?" With his eyes turned, Han Yi asked.

"It's above you."

"Is that right?" Looking down at the bottomless point below, Han Yi's face showed a sneer and said, "Then let them go downstairs and find me slowly."

After saying that, he didn't stop, and quickly climbed in the direction of the evil.

Of course, the climbing posture becomes extremely careful, trying not to leave any trace of passing.

Entering the artificial cave in twos and threes, Han Yi was slightly relieved and said, "Evil, where are they now?"

"It's almost the position you just said you were in. Well, go on."

"Hey, go down and find me slowly."

I ignored the three people. Han Yi turned his head and looked at the artificial cave and said, "Evil, where shall we go next?"

"Deep into this cave, after my exploration, it will take a distance of about kilometers."

"Oh." Nodding, Han Yi did not stop and immediately walked to the depths of the cave.

Under the seams 500 meters deep, there is almost no light here.

Walking all the way depends on the heart network.

Put the feeling to the largest. Not long after walking, Han Yi found the artificial ladder, but it went down.

"How deep is this ladder?"

"I don't know." Unexpectedly, the evil shook its head.

"You don't know?" Han Yi said with surprise on her face.

"Kid, I told you that my body is incomplete, right?"

Nodding, Han Yi said, "Well, you said that."

"Because of this, my current detection range is up to 1,000 meters, and I don't know if it's 1,000 meters away. The perception of the water of energy is a little farther away.

"However, there is one more thing." Speaking of this, the evil paused.

"One more thing?"

"That's time." Evil said helplessly, "I'm the only one left with the main brain. There is not much energy left in my body. Although I added some a few days ago, it's just a drop in the bucket."

"So, in addition to the position of sensing the water of energy, now I must save energy."

With a trace of helplessness in the evil tone, he said, "Otherwise, if I don't have enough energy...!"

"Forget it, I'll go down slowly by myself."

"However, boy, I have a way to find out everything here."

"What should I do?" Han Yi was stunned.

"Sona."

Evil said slowly: "If you can make a powerful enough ultrasonic wave, then I should be able to collect the sound that bounces back and convert it into a soona map picture."

"Sona? Are you asking me to shout? Here?" Han Yi was stunned and said immediately.

"Of course not. Shout here. You don't want to collapse here, do you? Although your current strength is still average, your throat is still strengthened.

"If you explode with all your strength, its sound is likely to collapse the cave. After all, this cave has existed for too long."

"And even if the cave does not collapse, such a loud sound is likely to be heard by the three people chasing down."

"So what should I do?" Listening to the evil words, Han Yi grabbed his head and said.

Soona, in the simulation war, he thought about it.

But it's a pity that it failed.

The evil said, "The sound wave frequency that can be heard by human ears is 20 to 20,000 Hz. When the vibration frequency of sound waves is greater than 20KHz or less than 20Hz, you can't hear it. Therefore, you also call sound waves with frequencies higher than 20,000 Hz "ultrasonic".

"However, as a hunter, your ears have been strengthened, and you should be able to hear this sound now."

"Ultrasonic refers to the transmission form of vibration state (or energy)."

"The so-called vibration refers to the form of round-trip movement of the particle of a substance near its equilibrium position."

"For example, after the drum surface is tapped, it vibrates up and down. This vibration state propagates in all directions through the air medium, which is the sound wave."

"Ultrasonic means that the vibration frequency is greater than 20,000Hz, and the number of vibrations per second (frequency) is very high, which exceeds the upper limit of human hearing (20000Hz). People call this kind of inaudible sound wave ultrasonic wave."

"So, if you want to make this kind of sound wave, you can't pronounce it as usual."

"Relying on the resonance of the chest cavity to produce vibrations inside your body, so as to emit ultrasonic waves."

"It vibrates once per second, at 1HZ."

"The vibration below 20HZ is generally not audible, so you can test it."

"When it is completely mastered, high-frequency vibration will be carried out."

"As long as the vibration generated in a second reaches more than a million times, then you can successfully send ultrasonic waves."

"Of course, as long as you successfully send out the ultrasound, then I can get the panoramic information here."

Listening to the evil for a long time, Han Yi understood a little.

The so-called ultrasonic test is vibration, which is pronounced in a vibrating way, rather than the usual way.

Understanding the mode of pronunciation, a smile immediately appeared on Han Yi's face.

It's too simple.

If ordinary people hear any chest resonance and resonate in their own body, it is definitely a blind person touching the elephant and can't figure it out why.

And Han Yi is different.

The reason is the muscle oscillation method. He has practiced the muscle oscillation method. He is very clear about vibration, especially chest vibration.
