What Levi thinks of is the sensory ability of animals. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

In Catherine's depiction, he understands that this groundhog who steals food and once made him a big embarrassment, and his greatest ability is this tremor perception.

But isn't this thing the ability to perceive ground vibration?

Although the perception diameter is one or two hundred meters, it sounds a little scary. But no matter how powerful it is, it's not like that in the end. Thinking of the birth of this little thing, Levi was not surprised at all. Even in the absence of magic on Earth, some digging animals have a specialty in this area. Moles, for example, will hit their heads into their burrows, emit a series of earthquake signals, and then use this tremor perception to receive each other to accomplish the purpose of communication.

After all, sound can travel in air, water, and substrates.

Similar to the mole, there is also the water strider. This kind of aquatic insects that float on the surface of the water and often appear on the banks of rivers and streams, and their communication method is to hit the water surface with their feet and emit shock waves.

These two, together with the general sense of hearing, combined with some other sensory systems such as touch and proprioception, constitute mechanistic sensation.

Levi remembers that there are five different types of sensory abilities corresponding to mechanical sensation, which are light, thermal, electrical, magnetic, and chemical.

Light perception is commonly referred to as vision. But its composition is not so simple. It can also be subdivided, such as the ability to perceive color, the ability to perceive brightness, the ability to see night and day, the ability to recognize the pattern of markings, etc.

Thermal sensation, i.e. the ability to perceive heat and infrared rays. Unlike photoreceptors, the number of animals with highly developed heat sensing abilities is very small. The most famous of these are the noctuidae and a few species of snakes such as vipers and pythons, as well as arthropods that parasitize warm-blooded vertebrates.

Electroreceptivity and magnetic sensation are the ability to perceive electric and magnetic fields. Many animals, including humans, do not possess these two senses at all. The most representative of the electroreceptor is the electric fish, which lives in some muddy rivers in Africa. In this environment, it is very difficult to distinguish between east, west, north and south by visually judging the direction, so the ability to touch bypass has developed. It has a special organ at the back of its body that emits a weak stream of electrical impulses, while the fish's head has receptors that can take in the slightest changes in the electric field around its body. By disturbing the electric field and breaking the symmetry, it is possible to perceive moving and immobile objects in the electric field. As for magnetic sensation, the more famous ones are pigeons. This street-wide bird can be navigated with magnetic fields.

As for chemical sensations, it is the sense of smell and taste. Like photosensing and mechanosensory, it is widely distributed in animals. Even for many animals, it is almost the only sensory ability.

Thinking of this, Levi's brain naturally sprang up a question - from a human point of view, which of these six sensory systems are relatively rare?

When it comes to mechanical sensations, the first thing that comes to mind is the echolocation ability of bats. This sonar system can be notoriously tight. On the other hand, the ability to accept infrasound waves is also not possessed by humans. There are also the mole's ability to listen to the ground, the water wave communication of the water strider, including the spider's ability to feel the tremor of the spider's web, and even the fish's ability to sense the direction of the water flow through the lateral line of the body.

Light perception, that is, vision, is also quite unusual. Although humans are known for their eyesight, the best of the best has its own strong hand. For example, the developed farsightedness of eagles, the low-light vision of cats, and the dark vision of many nocturnal animals, including the super-developed color sense of octopuses, are incomparable to humans.

Thermal, electrical, and magnetic sensations are simply heavenly things.

As for the final chemical sensations, which are taste and smell. In this regard, human beings are not very developed, otherwise they would not use "dog nose" to describe their sensitive sense of smell.

Levi nodded slightly.

At this moment, he suddenly had a feeling of seeing the sun.

Although as early as a month ago, when he first crossed over, Levi had the idea of using the knowledge of behavior. But the early work was basically occupied by the "Element Separation Experiment of Black and White Pythons Causing the Fear of Dragonborn Behemoths". Moreover, his ability at that time was too low, and he did not have the manpower and material resources for relevant research. After recovering the burn, he has been fighting lizardmen again in the past few days, and he is fighting openly and secretly with the princess in front of him, which makes him extremely tired, where is there time to think about this. Besides, the monsters in this world are all kinds of strange. Exactly where to start is also a big question. For a moment, he was confused.

This time, suddenly thinking of this, Li Wei suddenly found that "special sensation" is a good research direction. In addition to being used to fight, the ability of Warcraft can also be used in many ways, such as promoting production, accelerating industrialization, drug research and development, and so on. Besides, after having two dragon pets, he has no shortage of thugs.

These creatures with special senses can have a huge role, that is, the acquisition and transmission of information. In addition, he is also really curious about the demonic beasts living in this magical world, and what outstanding performance will be in this regard.

After thinking about this, Levi felt like a curious baby.

His mind was full of questions.

For example, what is the difference between the biology of Roland World and the Earth? Is there a food chain relationship between Warcraft?

Perhaps, it has just begun. Levi suddenly thought of this.

Winter Dragon City, the Earl's Mansion.

A room that is extraordinarily gorgeous, but has no doors or windows.

"Count Bard, I have something to tell you. Just now, I learned from Bishop Yaris that the 'Flame of Charles' has been extinguished. Do you know what that means?"

Bert didn't expect this to be the first thing he said, sitting on a chair covered with red fox fur, he looked incredulous.

This middle-aged man, who had an extremely majestic face, suddenly stood up and shouted to the person in front of him who was wearing a white robe: "How is this possible?"

At this moment, the eyes of this Earl of Winter Dragon were about to widen and protrude.

Bishop Bivis, who was very lanky, looked at him like this, and he gritted his teeth. "There is no doubt that Charles is dead! In order to save your unsuccessful son, he died!" Speaking of this, he breathed a particularly heavy tone, "Don't say that your son, even you, is not as good as Charles! There are only seven dragon knights among the millions of believers in my Holy Fire Church. Now for such a ridiculous reason, one has been lost, and you must take this responsibility for me......"
