"When did you gain this kind of attack ability?" Su Jing asked.
"I found it accidentally when I was looking for fish yesterday." The bat squeaked. Through the Ten Thousand Beasts Card, its voice sounded like a little boy, but it was a little hoarse. You have to listen carefully to hear it clearly.
"When looking for fish?" Su Jing was stunned for a moment, and then her eyes suddenly lit up, "Don't bats use ultrasonic waves to find prey? Could it be that the attack just now was an evolved ultrasonic attack?"
It is known that most bats have ultrasonic echolocation capabilities. The snouts and snouts of their heads have structures called "nose lobes", and there are very complex special skin folds around them. This is a unique ultrasonic device that has the function of emitting ultrasonic waves and can continuously Ultrasonic waves are continuously emitted. After the ultrasonic wave encounters an object, it will bounce back. After the bat receives it with its ears, it will know the specific location of the object, so that it can avoid obstacles and capture prey. It is simply a self-prepared radar.
Of course, ultrasonic attacks are not available to ordinary bats, because humans cannot hear bats' ultrasonic waves at all. Even if groups of bats emit ultrasonic waves together, humans will not react or feel any discomfort.
Therefore, Su Jing is still not sure whether the attack used by this bat is an ultrasonic attack. He checked the ultrasonic function online. He didn't know if he didn't check it, but he was shocked when he checked it. It turns out that ultrasonic waves can realize many functions according to changes in frequency. They have many applications in medicine, military, industry, and agriculture. They can be used for distance measurement, speed measurement, cleaning, welding, gravel, sterilization, etc. Su Jing focused on the military uses, that is, ultrasonic attacks, which are mainly divided into two types.
One is to emit sound waves with the same natural frequency as a certain object. Using the principle of resonance, it can shatter glass, tanks, submarines, fighter jets and other objects into pieces. However, this function is still under development even in the military and is difficult to realize.
The second is to use high-energy and high-frequency ultrasonic waves to create strong air pressure, which can cause physiological reactions such as blurred vision and nausea, thereby weakening the combat effectiveness of personnel or completely losing their combat capabilities, and more seriously causing death. This attack is so powerful that it can shatter glass. Even if you hide in tanks and air-raid shelters, you can't avoid it. It can even penetrate 15-meter concrete walls and tank steel plates.
"This bat king may be using high-frequency ultrasonic waves to create air pressure."
Su Jing took the Bat King and left on the golden eagle, ignoring the other bats. Without the leadership of the Bat King, the group was leaderless. The other bats could not cause chaos. If the five frigatebirds flew back, they could rule here again.
After Su Jing returned home, she couldn't wait to drive to a nearby store and bought an ultrasonic frequency tester. She wanted to confirm whether Bat King's attack was an ultrasonic attack. She said to Bat King: "For this, use the attack just now." .”
"Buzz" Bat King launched an attack without saying a word. The air seemed to be distorted. On the ultrasonic frequency detector, the data suddenly surged from zero. Su Jing saw the data jump to 20,000 Hz in the blink of an eye, and then soared to 35,000 Hz. The frequency range of sound that our human ears can hear is 20Hz-20000Hz, so sound waves beyond 20000Hz are named ultrasonic waves. This bat king's attack generates sound waves above 20,000 Hz, which is undoubtedly an ultrasonic attack.
What shocked Su Jing even more was that the data not only did not stop rising, but also soared rapidly within half a second. At the moment when she felt the air pressure, the data actually soared to 200,000 Hz, and then suddenly dropped. The data dropped to a few Hz. Obviously, the ultrasonic wave The attack is over.
"Oh my god, the moment the ultrasonic attack occurred, the frequency reached 200,000 Hz, ten times the lower limit of ultrasonic waves. This is undoubtedly a high-frequency ultrasonic wave." Su Jing was shocked. Of course, he knew that the reason for the ultrasonic attack was probably not only because of the high frequency, but also because the ultrasonic power was also extraordinary. However, the power of bat ultrasonic waves cannot be detected with this ultrasonic frequency tester, and we don’t know what the specific value is.
Su Jing continued testing and found that this bat king not only had an exaggerated upper limit of ultrasonic frequency power, but also achieved a qualitative leap in ultrasonic range and fine control. The big-footed myotis bat's ultrasonic echolocation ability is not among the strongest among bats because their prey is fish and the water surface is flat, which is not as complicated as catching mosquitoes in the woods. Therefore, the echolocation ability has degraded and the detection of prey is not accurate enough. However, this big-footed myotis bat, let alone degenerated, has simply evolved to another level.
Su Jing made a lot of densely packed threads in a box. The gap could only pass through King Bat's body. She tied bells on them and put ten mosquitoes in. After the mosquitoes dispersed, she said to King Bat: "King Bat, Caught ten mosquitoes as quickly as possible without touching the bell."
The Bat King squeaked and flew into the box. For such a small box and so many dense threads, it flew extremely fast, shuttling between countless chaotic threads, and mosquitoes fell into it one after another. In his mouth, it only took about twenty seconds for Bat King to catch all ten mosquitoes. Not a single bell was touched. One can imagine how powerful the ultrasonic echolocation ability is.
"This bat is so powerful. If you continue to cultivate it, you will definitely become a capable person in the future." Su Jing was overjoyed. This bat she got by chance was simply more powerful than most of the pets she had cultivated.
However, Su Jing estimated that there was an element of luck involved, something that could only happen by chance. Many pets have eaten more jade-toothed fish and have not evolved so obviously. Among such a large group of bats, only one has evolved like this. It shows that it is not enough to keep feeding the Jade Tooth Fish and keep cultivating it. It also depends on genes and talent. This bat is probably a one-in-a-million prodigy. Maybe even if there is no Jade Tooth Fish, as long as the living environment changes, it will become the first individual to evolve.
This also gave Su Jing a new idea about breeding pets. If there are enough jade tooth fish in the future, a large-scale feeding plan can be adopted, so as to maximize the extraction of some individuals with exceptionally strong genes. Otherwise, if the individual selected at the beginning looks strong on the surface, but in fact the underlying genes are not very good, it will be difficult to achieve a breakthrough after training.
At this moment, the alarm suddenly rang on the phone. Because he was too focused on testing the bat, Su Jing didn't notice that it was already three or four in the morning. His eyes lit up and he ran quickly to the first floor with his pets.
