The so-called infrasound wave refers to the sound wave below 20 Hz, which is similar to the natural frequency of the human organ, so it will resonate, which can lead to the deformation, displacement and even rupture of the organ. In fact, this is the same as the main principle of ultrasonic weapons, the frequency of ultrasonic is similar to the frequency of tanks, so it is the tank that is shattered.

That is to say, for the human body, infrasound waves are more destructive, ultrasound waves can only cause air pressure, indirectly harming people, while infrasound waves act directly on the human body.

Of course, the same infrasound waves also have high and low frequencies, adjusting the frequency can change the impact on the human body, the infrasound waves emitted by Dr. Qin's instrument have little impact on the human body, and the natural frequency of the bat body is similar to that of humans, so it does not have much impact on Xiao Hei, only a little dizzy, but it has a great impact on Xiao Jin's body, so Xiao Jin controlled by Ye Ning fell directly to the ground.

"Who is this Dr. Qin?"

Ye Ning had a deep fear of this help invited by the Lin family, controlled Xiao Hei, and swooped down, judging from Dr. Qin's reaction, it was obvious that he didn't find Xiao Jin who fell to the ground, maybe this Dr. Qin just saw that the ultrasound was ineffective, so he switched to infrasound, and hit Xiao Jin's death hole by mistake.

Ye Ning smashed the window with a large stone that he was grasping with his claws, and flew directly into the hall while the ultrasonic wave was released.

"Buzz."

Since Dr. Qin has switched to infrasound, it is naturally impossible to offset some of Xiao Hei's ultrasonic attacks, Li Suting, Lin Haoran, Lin Rui, Dr. Qin, and nearly ten bodyguards in the room are all dizzy, among which Li Suting and Lin Haoran fainted directly, a woman and an old man, and their physical fitness is naturally worse.

Ye Ning didn't save Xiao Jin first, but pounced directly on Dr. Qin, as long as he was solved, everything would be fine.

"What a big bat, Dr. Qin be careful." Lin Rui was shocked, he had learned about the scene where his son was attacked by a bat, and he only knew that a bat carrying a scalpel was one or two times larger than an ordinary bat, but the bat in front of him was not only one or two times bigger, but more than ten times bigger.

"Finally showing up." Dr. Qin was obviously surprised by Xiao Hei's size, but he didn't panic at all, and opened his mouth to blow a sharp whistle.

At the same time, a huge bird shot out of the inner chamber at a rapid pace, blocking Blackie's path.

Ye Ning was startled, and did not rashly choose to confront it head-on, but used ultrasonic echolocation, and his body suddenly bypassed quickly, avoiding the raptor, and then looked back at the raptor, Xiao Hei's eyesight was always a shortcoming, although he broke through to the late stage of training, but it was only a little stronger than ordinary humans, and he couldn't see the raptor clearly in the process of passing by quickly.

When he looked back, he saw that the bird of prey made a sharp turn in the air, and then turned around and rushed towards him, its wings were more than two meters long, its toes were more than 20 centimeters, and a pair of bright eyes were staring at him with a fierce light.

"Is this ...... Harpe carving? ”

Ye Ning's heart was shocked, even in the late stage of training, he didn't dare to hold it up at all, and instantly raised his vigilance.

During this period of pet store operation, Ye Ningxin got to know many animals, including this bird of prey, and he knew how terrifying it was.

The Harpe eagle is not a "carving" in the true sense, but a species between the eagle and the buzzard.

The word "hape" is derived from ancient Greek mythology, originally referring to a half-human, half-bird monster that was given the name by early Western explorers who arrived in the Americas because of its fierceness. Later ornithologists called it the "air jaguar" and the "great white shark of birds".

The Harpe eagle has a keen eye and extraordinary hunting ability, in the air of nearly 50 meters, the Harpe eagle can clearly see an ant on the ground, chasing prey at speeds of up to 80 kilometers per hour. There are about 19 species of prey, mostly arboreal mammals, especially spider monkeys and howler monkeys, as well as sloths, anteaters, long-snouted raccoons, opossums, and more.

In the face of such a terrible bird of prey, if Ye Ning is careless, he is asking for his own death.

"The flight speed of this Hape eagle is estimated to be more than 80 kilometers, and it is faster than Xiao Hei in terms of straight line flight, is it because it has been trained by Dr. Qin?"

Facing the Hape Eagle that rushed over, Ye Ning released the ultrasonic wave again, and the Hape Eagle's body was obviously shocked, and he paused slightly, but it was less affected than a person, and he recovered quickly.

Of course, such a short pause had already created an excellent opportunity for Ye Ning, Ye Ning was about to take the opportunity to attack, but he felt a feeling of dizziness again, and out of the corner of his eye, he caught a glimpse of Dr. Qin facing him with an instrument, and it was estimated that it was another infrasonic attack.

In other words, Ha Pei Diao and Ye Ning were both dizzy and canceled each other out.

"Fighting here is not good for me." Ye Ning flew into the inner room, firstly, to avoid Dr. Qin's infrasonic attack, and secondly, the narrower and more complicated the terrain, the more beneficial it was to himself, and he could use ultrasonic echolocation to easily dodge, which was definitely not comparable to Harpe's eagle.

It's a pity that Ye Ning's wishful thinking was not achieved, seeing that the Ha Pei Eagle was about to chase into the inner room, Dr. Qin whistled, and the Ha Pei Diao stopped, but when it stopped, it was about to hit the door of the inner room, and the claws grabbed the door frame buffer, and directly scratched the door frame with a few deep scratches, the claw power can be seen, Xiao Hei's defense is still weak after all, if he is caught, he will definitely be seriously injured.

"Xiao Jin is still under infrasonic damage, and he can't delay any longer."

Ye Ning first used the turtle shell in the center of his eyebrows, and directly transferred the Yuan Essence into Xiao Jin's body, barely stabilizing its injuries, the turtle shell can not only collect the Yuan Essence of each clone anytime and anywhere, but also inject the Yuan Essence into any clone anytime and anywhere.

Then, Ye Ning flew to the kitchen of the Lin family, grabbed a kitchen knife, and flew back to the hall.

Fortunately, when they were fighting with the Harpediao, the bodyguards were worried that they would accidentally injure the Harpedia, and they wouldn't shoot, so they didn't need to take care of both, of course, the shooting of the pistol was difficult to shoot themselves, although it couldn't be said that they could dodge the bullets, but the bodyguards' reaction couldn't keep up with their speed at all, let alone aim and shoot, Lin Haoran and others were also indoors, and the bodyguards would definitely not use machine guns indoors to sweep, and with a pistol, the possibility of hitting themselves was extremely low.

"Buzz"

At the same time that Ye Ning used ultrasonic attacks, he was also attacked by Dr. Qin's infrasonic waves again.

However, Ye Ning had already prepared and mobilized the Yuan Jing early in the morning, so he recovered extremely quickly and seized the opportunity at the moment.

"Huh"

Ye Ning controlled Xiao Hei's body to be extremely flexible, like a piece of black mist without substance, flying past the body of the Harpe eagle.

The kitchen knife grasped by the claws slashed fiercely at the chest of the Ang Hape eagle, and under the severe pain, the Hape eagle also instantly regained consciousness, and the sharp and powerful claws grabbed Xiao Hei's wings and grazed them.

A carving and a bat passed by, and Ye Ning was slightly better.

But fortunately, Ye Ning had Yuan Jing repaired, quickly took a breath, and instantly turned around and counterattacked.

This ability to turn back quickly, the Harpe Eagle is obviously not as good as the bat, and it can't react at all.

"Snort", Ye Ning slashed the kitchen knife on the neck behind the Hape carving, originally this knife was enough to kill, but at the last critical moment, Ye Ning kept his hand, and the kitchen knife did not continue to cut, anyway, this knife was enough to make the Hape Eagle lose its combat power, and then I am afraid that it will not be able to stand without its own treatment, the Hape Eagle is an endangered species, extremely difficult to see, it is a pity to die like this, if it can be accepted as an animal clone, it is a good choice.

Ordinary Hape eagles are "air jaguars" and "great white sharks among birds", if you add cultivation, it will be worth it.
