There are 23 modern animal exhibition halls in the forest zoo, including the Birds' Song Forest, the Golden Monkey Hall, the Waterfowl Hall, the Children's Animal Village, and the Rhino Hall. There are also 5 large-scale areas including ligers and tigers, large herbivores, and wolves. A total of more than 5,000 animals (heads) of more than 240 species are on display. The park area is home to more than 40 species of migratory and resident birds, including pheasants, pigeons, and finches, and more than 20 species of mammals, including hares, wolves, and ferrets. The green coverage rate of the park area reaches 95.8%. The main tree species include more than 50 species such as larch, Korean pine, Scotch pine, yellow pineapple, walnut tree, linden, oak, poplar, and white birch.
"Let's go and feed the elephants together."
In the roaming area, many tourists are feeding the elephants some grass or sugar cane.
Next to the elephant stands the keeper.
Lin Meiqi ran over and picked up a piece of sugar cane to feed to the elephant.
"Hurry up and take pictures for me."
She urged there while striking some cute poses.
Lu Ning took a few photos of her, and she snatched the phone away.
And he was looking at the elephant in a trance.
Information about elephants began to come to mind.
Elephants have three abilities that are different from other animals.
The first ability: infrasound waves.
Not only can elephants hear infrasound waves, they can also emit them. This is unique in the animal kingdom.
Elephants can emit sound waves of about 10Hz, which are infrasound waves. Communication between elephants is usually infrasound waves, which are inaudible to humans.
The elephant's hearing frequency range is from 1 Hz to 20,000 Hz.
The frequency range of sound that humans can usually hear is 20 Hz to 20,000 Hz.
Elephants can communicate using infrasound waves that are inaudible to humans, and can generally travel up to 11 kilometers without interference.
The second ability: smell.
Elephants have the best sense of smell among animals, more than five times that of dogs. Apart from bears, it has the most sensitive sense of smell in the living world. Although its sense of smell is not as strong as that of a bear, it has the most olfactory genes among all animals, so its sense of smell is the most reliable.
The third ability: Elephants are basically immune to cancer.
Now research has shown that only naked mole rats do not get cancer. But except for naked mole rats, elephants have the lowest risk of cancer, with only 5% of elephants dying of cancer.
You must know that the larger the body, the greater the risk of cancer, and why is it difficult for elephants to get cancer.
This is about a tumor suppressor gene called TP53.
This gene produces a protein called P53, which is responsible for monitoring the integrity of the gene and promoting DNA repair if it detects DNA damage. If there is no way to repair it, the apoptosis program will be initiated, inducing bacterial 'suicide' to prevent these abnormal cells from getting out of control and turning into cancer cells.
The number of copies of the TP53 gene in elephants is 20, while ordinary animals and humans only have one copy of TP53, which is equivalent to 20 copies of insurance on elephants. So elephants basically don’t get cancer.
Moreover, the TP53 gene is not only powerful in suppressing tumors, but is also very efficient in clearing abnormal cells.
The TP53 gene is the natural guardian of organisms.

"What are you doing? Come here and take a picture for me."
"Come on, let's take a photo together, 123 Eggplant~"
Lu Ning was dragged by Lin Meiqi to take pictures. After a while, his phone received a photo of the two of them together.
Not to mention, it’s pretty good-looking.
"Don't you think it looks pretty?"
"I'm pretty, but you look so stupid."
"Let's go, let's go to the next venue."
Lin Meiqi said hello and ran in first, following the team in front.
In front is a liger and tiger roaming area.
There are beasts at every glance.
By the way, tigers can also emit infrasound waves. The roar of tigers in the mountains is no joke.
Continuing forward, we soon came to the aquarium.
People flocked to the aquarium to watch the dolphin show.
When he saw the dolphins, Lu Ning thought of the dolphins' abilities.
The hearing of dolphins is second to none in the biological world. It can hear sounds between 150 Hz and 150,000 Hz, and can also emit sounds between 7,000 Hz and 120,000 Hz. There is also advanced echolocation, which emits sound waves and processes the reflected waves, allowing them to identify what is ahead, not only the location of the object, but even the size and shape of the object.
It is a natural B-ultrasound in nature.
The principle of vocalization of dolphins is different from that of other mammals. It does not have vocal cords for production. There is a breathing hole on the top of its head, with valves inside. When air enters the breathing hole, it can use the valves to adjust the size of the airflow, thereby making sounds of different pitches.
It has two horn-shaped air sacs on its front jaw that can directionally emit sound waves. The sound waves it emits are not of a single frequency, and the speed can also be changed. When receiving, the jaw receives high-frequency sound waves and the ears receive low-frequency sound waves.
-------------
After watching the performance, Lin Meiqi went up to take photos with the trainer and the dolphins.
After leaving the dolphinarium, they moved on.
Next is the bird area.
The bird area includes peacocks, ostriches, emus, golden eagles, vultures, vultures, falcons, black swans, white swans, mandarin ducks, pelicans, gray geese, bean geese, bar-headed geese, white-fronted geese, mallards, and red shelducks. , painted-faced duck, turned-nosed shelduck, etc.
These include goshawks and sparrowhawks.
Eagle is the ability that Lu Ning wants to get more. Unfortunately, there are glass and nets to isolate them, making contact impossible.
"Why are you always staring at it? Do you still want to go to heaven?"
Lin Meiqi chuckled when she saw Lu Ning staring at an eagle in the garden.
“Who wouldn’t want to go to heaven if they could?”
"We can fly. We didn't fly here just yesterday. You won't forget it, right? Poor child, maybe you have amnesia!"
Lin Meiqi showed an exaggerated expression and looked at him with wide eyes.
Lu Ning gave her a look.
This guy likes to make jokes like this.
He turned his head and looked at the eagle again. The eagle seemed to be a little lazy because of being imprisoned.
Having no worries about food and clothing, but losing freedom is like how many people do.
You can't have your cake and eat it too.
----------
After seeing so many animals just now, Lu Ning's heart was already a little excited.
He hesitated whether to copy the abilities of elephants or dolphins. One is infrasound and the other is ultrasonic, which is a bit confusing.
He really wants to send a post to netizens - if it were you, what would you choose?
Well, only children make choices, adults of course want both.
Well, yes, Lu Ning thought so too.
So when the two of them walked back after visiting the zoo, Lu Ning copied the elephant's ability.
As for the dolphins, we can only talk about it later.
Why copy the elephant first.
The reason is simple, because infrasound can be used as a means of attack, while ultrasonic is more of an auxiliary.
The assistance has no practical effect for the time being, but Lu Ning is more interested in the attack ability of infrasonic waves.
Sound waves with a frequency less than 20Hz (hertz) are called infrasound waves. Infrasound waves are not easily attenuated and are not easily absorbed by water and air. Infrasound waves tend to have very long wavelengths, so they can diffract around certain large obstacles. Some infrasound waves can circle the earth 2 to 3 times. Infrasound waves of certain frequencies are close to or even the same as the vibration frequency of human organs, so they easily resonate with human organs and are very harmful to the human body. In dangerous cases, they can cause death.
A 7000Hz sound wave can be blocked by a piece of paper, while a 7Hz infrasound wave can penetrate more than ten meters of reinforced concrete. Infrasound waves generated by earthquakes or nuclear explosions can destroy houses on the shore. If infrasound resonates with surrounding objects, it can release considerable energy. For example, infrasound of 4Hz-8Hz can resonate in the human abdominal cavity, causing strong resonance in the heart and damage to the lung walls.
Such powerful infrasound waves have already been studied intensively by major countries.
The military application of infrasound waves, for example, can use the strong penetration of infrasound waves to create infrasound weapons that can penetrate tanks and armored vehicles. Infrasonic weapons generally only harm people and do not cause environmental pollution.
In 1986, due to technical negligence during an experiment in a certain country, infrasound waves rushed out of the laboratory, resulting in the inexplicable deaths of 30 residents 16 kilometers away from the laboratory.
Infrasound bombs can kill everyone within a radius of ten kilometers in an instant, whether in the air, on the ground, underground, or in the water.
Infrasonic weapons are divided into two categories: neural infrasound weapons and organ-type infrasound weapons.
The infrasound frequency of organ-type infrasound weapons is the same as the natural frequency of human internal organs (4-18Hz), causing strong resonance in human internal organs.
The infrasound frequency of neural infrasound weapons is the same as the alpha rhythm of the human brain (8-12Hz), which directly affects the human brain.
Both can cause physical discomfort in mild cases and death in severe cases, so this kind of infrasonic weapon cannot be protected by covering your ears. Moreover, during the development of infrasonic weapons, it was discovered that once fired, this weapon will cause damage to the enemy regardless of friend, unless one's own side carries out special protection in advance or is outside the weapon's range of action.
But it has obvious advantages. It has a long attack range and strong penetrating power. It can directly cause injury or death without causing damage. It has strong maneuverability and can be used by individual soldiers and aircraft.
The great road is invisible, and the great sound is silent.
It is terrifying to think about a person dying for no reason under an infrasonic attack.
By copying the elephant's ability, Lu Ning will be able to do this kind of attack.
For a moment, he was looking forward to it.
