Luo Feng only felt a feeling of dizziness surging into his head, how mysterious this feeling was! But in the next second, Luo Feng discovered the extraordinary!

This is a high-frequency conversion of ultrasound and infrasound!

As we all know, ultrasound and infrasound are two sounds that are very much beyond the scope of human hearing. The pen "Fun" Pavilion www.biquge.info even Luo Feng is no exception to hear it!

However, ultrasound is beneficial to the human body within a certain range.

And infrasound is harmful to human beings and not beneficial!

Ultrasonic is a sound wave with a frequency higher than 20,000 Hz, which has good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and has a long propagation distance in water, which can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization and disinfection, etc......

Sound waves with a frequency of less than 20 hertz are called infrasound.

Infrasound waves are not easily attenuated and are not easily absorbed by water and air. Moreover, infrasound waves tend to have a very long wavelength, so they can diffract around certain large obstacles, and some infrasound waves can circle the earth for 2 to 3 times.

Some frequencies of infrasound waves are similar to the vibrational frequencies of human organs. It is easy to resonate with human organs, has strong damage to the human body, and can cause death when dangerous!

There have been people on the battlefield and ships that have dropped infrasonic launchers! This kind of weapon is even more terrifying than some modern explosives and so on!

Your own army is gone, and the opponent's army is also wiped out!

Luo Feng dared to guarantee that the dizziness and swelling pain he felt in his head now was definitely from the infrasound!

Luo Feng's expression sank, and he immediately opened the door, "Pretend to be a ghost!"

Outside the door, a man looked at Luo Feng with the corners of his mouth raised, holding a very small horn in his hand, and a very small machine was connected to the bottom of the horn!

Needless to say, ultrasound and infrasound waves were emitted by this artificially assembled gadget.

This man looks exactly like a doctor. Wearing a white coat and eyes, he is about 40 years old, but he looks quite a middle-aged uncle's mature charm! When he was young, he must have been very handsome.

Especially his physique, the aesthetic figure in the eyes of a standard American woman!

Luo Feng has no interest in men, and he will not show mercy to enemies who are unfavorable to him. Without saying a word, Luo Feng stretched out his hand and probed the man's throat!

The man looked calm, and there was a faint look of bewitching on his face! When he saw Luo Feng stretching out his hand, he dodged it very easily!

"Mr. Luo, I've finally found you!, however, this is not the place to fight, why not go to the rooftop to have a try?" The man was polite, but a real killer.

There are three kinds of people in this world who want Luo Feng's head! The first is the enemy, the second is the person who lacks money, and the third is the neurotic of murderous fantasy!

Needless to say, the person in front of him made Luo Feng feel the same aura as the black-haired old man and the white-haired old man who had been knocked out by Luo Feng before. This man must be an enemy!

Of course, if the enemy kills Luo Feng, it is enough to take his head to accept the reward and become a local tyrant!

The person in front of him was dressed and didn't seem to be short of money.

Luo Feng snorted coldly, "I'm afraid I don't have to go to the rooftop to deal with you!"

The man sneered, but that wasn't necessarily!

The corners of Luo Feng's mouth twitched, "If you want to force me to go to the rooftop to fight, you can! However, you have to prove that you have the strength to let me give you this respect!"

As he spoke, his fist was like the wind, but it was as silent as the night, and he came to the man's eyes in an instant.

This time, Luo Feng has exerted seventy percent of his speed and strength!

To Luo Feng's surprise, the man actually dodged Luo Feng's hand and easily grabbed Luo Feng's fist!

Luo Feng took his hand back, and a strange evil smile suddenly rose on the corner of the man's mouth.

He said: "Wolf King Luo Feng, if you have the guts, follow me to the rooftop!"

After saying that, the man walked away directly and took the stairs to the rooftop!

This is the 6th floor, and the rooftop is on the 28th floor!

If it was Luo Feng, it would take more than 2 minutes to climb up with a wind step!

Luo Feng didn't do that.

He turned around, looked at Xin Moling, who was sitting on the bed and looked at Luo Feng a little blankly, pursed his lips, and then said, "I'm afraid that person will use a trick to divert the tiger from the mountain to you! You put on your clothes and go to the rooftop with me!"

Xin Moling was stunned, "Will I affect you?"

"No!" Luo Feng said confidently: "With me here, who dares to bully you?"

Xin Moling's heart warmed, she pursed her lips and nodded sweetly, got out of bed and quickly put on her clothes, and didn't forget to take her camera, and followed Luo Feng out of the house!

How did Luo Feng go up?

He's not as stupid as the Yankee!

Xin Moling looked at Luo Feng's calm expression, and couldn't help but feel guilty in her heart, "Luo Feng, I ...... just now I'm sorry, I misunderstood you. ”

Although she felt guilty, after knowing that someone had really come to the door, Xin Moling was a little happy. That shows that Luo Feng is not resisting her!

At the same time, because Xin Moling was thinking about the matter between him and Luo Feng, he directly ignored the bad intentions of the person who came to the other party.

Perhaps, what she didn't realize was that staying with Luo Feng, the sense of security that was born invisibly was enough to make her forget all the dangers!

On the rooftop, the man was already standing in the middle, very calm and indifferent, quietly waiting for Luo Feng's arrival.

Seeing that Xin Moling was also here, the man was not surprised. On the contrary, with Xin Moling here, there was a sharp light in his eyes!

There are beautiful women!

A bright smile spread across the man's face.

"Who asked you to come?" Luo Feng sneered: "I'm afraid those two old men are not dead, otherwise you wouldn't have come to the door so calmly, right?"

"It doesn't matter whether those two old men live or die! The point is, their deaths are very valuable! If it weren't for them, the boss really wouldn't know that the famous wolf king had actually come to Los Angeles!" The corner of the man's mouth grinned, and he said confidently: "I don't mean anything else, but I heard that the wolf king's head is very valuable, so I want it to move, you have no opinion, right?"

"Heh, the momentum is good!" Luo Feng protected Xin Moling behind him, so that he didn't have to worry, and immediately walked five meters in front of the man. He said: "There are more people who want my head to move! But they have not succeeded! Since you are talking wildly, if you lose, I will also let you move your head to experience the experience!"

"Haha......" The man smiled, and then his face turned cold, "Then try it!"

As he spoke, he clasped his hands, and under the force of his whole body, the muscles of his body instantly expanded! Immediately, the color of his body turned to emerald green, and his height directly grew more than two meters!

He's transformed!(To be continued.) )
