Galactic Garbage Station

"When did you have this kind of attack ability?" Su Shi asked.

"When I was looking for fish yesterday, I found it by chance." The bat screamed, and through the beast card, its voice sounded like a little boy, but it was hoarse and should be listened carefully to hear clearly.

"When looking for fish?" Su said, and then his eyes suddenly lit up. "Bats are looking for prey, aren't they using ultrasound? Is it just that the attack is an evolutionary ultrasound attack?"

As we all know, most bats have ultrasonic echolocation capabilities. They have a structure called "nose-like leaves" on the snout of their heads, and there are complex special skin wrinkles around them. This is a peculiar ultrasonic device that has the function of transmitting ultrasonic waves and can be continuous. Ultrasonic waves are continuously emitted. When the ultrasonic wave encounters an object, it will bounce back. When the bat receives it with the ear, it will know the specific position of the object, so that it can avoid obstacles and catch prey. It is simply a self-prepared radar.

Of course, the ultrasonic attack is not available to ordinary bats, because humans simply can't hear the bat's ultrasound. Even if hordes of bats emit ultrasound together, humans will not react and will not have any discomfort.

Therefore, whether the attack used by this bat is an ultrasonic attack, Su Shi is still not sure. He checked the ultrasound function on the Internet, and did not check it. The original ultrasonic wave can realize many functions according to the change of frequency. It has many applications in medicine, military, industry and agriculture, and can be used for ranging, speed measurement, cleaning, welding, crushing stone, sterilization and the like. Su Shi focused on the military use, that is, ultrasonic attacks, mainly divided into two types.

The first is to emit sound waves of the same natural frequency as an object. The resonance principle can be used to smash objects such as glass, tanks, submarines, fighters, etc., but this function is still developing militaryly. difficult to realize.

The second is the use of high-energy high-frequency ultrasound, resulting in strong air pressure, causing people to have visual ambiguity, nausea and other physiological reactions, so that personnel combat strength is reduced or completely lost combat capability, and more serious death. This kind of attack is powerful enough to shatter the glass. Even if you hide in a tank and a bomb shelter, you can't avoid it. It can even pass through 15 meters of concrete walls and tank steel plates.

"This bat king may use high-frequency ultrasound to cause air pressure."

Su Shi took the bat king and rode the golden eagle to leave. He ignored the other bats and lost the bat king. The dragons had no heads, and other bats could not create confusion. When the five warships fly back, they can re-rule here.

After Su Shi came home, she couldn't wait to drive to a nearby store and bought an ultrasonic frequency tester. I wanted to confirm whether the attack of the bat king was an ultrasonic attack. Said to the bat king: "To this, use the attack just now."

"嗡" The bat king did not say anything, attacked, and the air seemed to be distorted. I saw the ultrasonic frequency detector, the data suddenly rose from zero. Su Shi saw the data blinking to 20,000hz, and then soared to 35000hz. The frequency of sounds that we can hear in human ears is 20hz-20000hz, so the sound waves that exceed 20,000hz are named ultrasonic waves. This bat king attack produces sound waves above 20,000hz. There is no doubt an ultrasonic attack.

What shocked Su Shi was that the data did not stop rising, and it quickly soared in half a second. At the moment when the air pressure was felt, the data actually reached 200000hz, and then suddenly dropped, the data fell to a few hertz, obviously ultrasonic The attack is over.

"Oh my God, the moment of the ultrasonic attack, the frequency actually reached 200000hz, reaching ten times the lower limit of the ultrasound, which is undoubtedly high-frequency ultrasound." Su Shi shocked. Of course, he knows that the reason for the ultrasonic attack is not only because of this high frequency, but also because the ultrasonic power is not trivial. However, the power of the bat's ultrasonic wave cannot be detected by this ultrasonic frequency tester, nor what the specific value is.

Su Shi continued to test and found that this bat king, not only the ultrasonic frequency power limit reached an exaggerated point, but also a qualitative leap for the ultrasonic range and fine control. The ultrasonic echolocation ability of the big-footed bat is not strong in bats, because their prey is fish, the water surface is flat, not as complex as the woods catching mosquitoes, so the echolocation ability is degraded, and the detection of prey is not accurate enough. However, this big-footed rat bat, let alone degenerate, has evolved to another height.

Su Shi made a lot of dense lines in a box. The gap could only pass through the body of the bat king, tied with a bell, and got ten mosquitoes in. When the mosquitoes spread out, they said to the bat king: "The bat king, Ten mosquitoes were caught at the fastest speed without touching the bell."

The bat king screamed and flew into the box, so a small box, so many dense lines, it flew very fast, shuttle between countless chaotic lines, one mosquito after another fell into it In the mouth, it took only twenty seconds, and the bat king grabbed all the ten mosquitoes. No bell was touched, and how strong the ultrasonic echolocation ability is, it is conceivable.

"This bat is too powerful, continue to train, and will be able to become a capable cadre in the future." Su Shi is very happy, this accidental bat is more powerful than most of the pets he cultivates.

However, Su Shi estimates that this has a luck component that can be met. Many pets have eaten more jadefish, and there is no such obvious evolution. Only a large group of bats have evolved into this. Explain that it is not always necessary to continue to feed the jadefish. It depends on the genes and talents. This bat is estimated to be a talented one. Perhaps even if there is no jadefish, as long as the living environment changes, it will become the first evolutionary individual.

This also gave Su Shi a new idea for cultivating pets. If there are enough jadefish in the future, they can adopt a large feeding scheme, so that they can extract the most powerful individuals themselves. Otherwise, if the individual's surface at first is strong, but the potential genes are not so good, it is difficult to achieve breakthroughs.

At this time, the phone suddenly sounded an alarm, because too much to test the bat, Su Shi did not notice that it had reached three or four in the morning, his eyes lit up, with the pets quickly ran to the first floor. (To be continued~^~)
