Seeing that the little lightning bolt was like himself, drilling through the hole in the window, Sun An immediately realized a characteristic of these special currents, they could not penetrate objects, but could only drill into the gaps.

Then as long as there is a confined space, you can block the attack of small lightning.

But this is obviously unrealistic, the shopping mall below the hotel is a huge open space, and the large freezer on the catering floor is a confined space, but Sun An doesn't know where the freezer is, or even where the catering floor is, and it's too late to find it now.

This feature can no longer be used, but more can be found that can be used, there is no perfect thing in the world, there are one and two, as long as you look patiently and observe carefully, you can always find more.

Ran to the door of the Yuangong area, Sun An pushed the door out, closed the door, thought about it, took a coat from a nearby store, blocked the crack of the door, and then ran to the patio and looked down.

There is also a glass door behind the hollow roller shutter door, which is also closed, in order to prevent dust, the door gap is not large, and small lightning can get in, but the space is limited, so the speed of drilling in is relatively slow, and until now, the floor on the first floor has not been paved.

This is another characteristic, small lightning can't overlap together, electricity is invisible, but these small centipedes seem to have a collision volume, which also makes sense, very small electric centipedes can't bite people, but coarse ones can, if there is no collision volume, they can be combined together to form a big centipede, which is more powerful, but if they are merged, the coverage area and density are not large enough, so you can't find the target to be shocked.

However, the collision volume cannot be used, the environment has restricted their movement, and Sun An does not have the ability to destroy the building to create a confined environment.

However, through this feature, he realized a problem - how did these living lightnings find their targets?

The sensing distance is very short, they must come to the vicinity of the target to sense, and then drill into the body from the soles of the feet, there will be almost no reaction from the distance, then the target must be determined by some method, when they encounter a dead object, even if it is a humanoid model, it will not drill into the electricity, the electricity will only be a living thing.

Body temperature? Sun An's first reaction is temperature, snakes are determined by sensing temperature, and small lightning looks like snakes; carbon dioxide is the second reaction, mosquitoes determine the target location according to the concentration of carbon dioxide, and they can also sense temperature when they can't find carbon dioxide.

Organisms have long evolved a variety of detection techniques, mosquitoes are very weak, one slap to death, they are located at the bottom of the food chain, many insects, birds, reptiles, amphibians will prey on mosquitoes, but they are also predators, all homeothermic animals are their targets, so some people call mosquitoes the existence at the top of the food chain.

These little lightning bolts also behave like predators, and if you can know how they prey, you can dodge them.

It is impossible to lower his body temperature, at most he can hold his breath for a period of time, when he is still, Sun An can hold his breath for about four minutes, and when he moves, it will be two minutes, after all, he smokes, which will cause great damage to the respiratory system.

In the face of the overwhelming lightning bugs, holding your breath for two or three minutes has no effect.

Among animals, what other methods are used to find and lock on to prey? Most animals are through their eyes, and predators such as cats and eagles have very keen vision; secondly, the sense of smell, dogs' sense of smell is sixty or seventy times stronger than that of humans, and they are the best helpers of the anti-narcotics police, although the sense of smell of pigs is about ten times stronger than that of dogs; and the third is the sense of hearing, not to mention the ultrasound of bats, although most animals use their sense of hearing to avoid predators.

What else? Little Lightning has no eyes, nose, or ears, so these methods are not used, and what special hunting ability does it have?

Sun An walked in the shopping mall, where the space was indeed very large, and it would take a long time to fill it, giving him room to think.

The smooth, white floor of the patio on the first floor has been covered with small lightning bolts, constantly moving, dotted with stars, shining beautifully, more beautiful than the sea at sunset, not at all as disgusting as crawling with snakes, but unfortunately falling into it is no better than falling into a snake's nest.

Walking around the corridor by the courtyard on the third floor, Sun An suddenly stopped and looked down.

Spider!

Spiders have a special hunting skill, that is, to sense vibrations, the bristles on their feet can make them sense very small vibrations, web-weaving spiders can feel the vibrations of spider webs, and immediately crawl to the prey where the webs are sticking, burrowing tarantulas will dig a hole by themselves to hide inside, feel the approach of their prey through the vibration of the ground, and then crawl out to attack.

Small lightning bolts can only swim on the surface of objects, they can feel the vibration of the ground, and the vibration does not need the assistance of eyes, nose, or ears, as long as it is in contact with the ground.

"And the voice. Sun An immediately thought of this, the sound was the vibration of the air, and if his conjecture was correct, then his presence could also be felt through the sound.

It is difficult to find a target by body temperature and carbon dioxide concentration, but it is easy to test by sound, as long as he can make a sound, Sun An immediately picked up a model and threw it down the patio.

The model smashed, her head, hands and feet separated from her body, and rolled to the side, and a small lightning bolt in the vicinity immediately rushed up and burrowed into the model.

"Ah, burrowing into an object means releasing an electric current, which is equivalent to suicide, it's not that they can't get into the object, they don't intend to do it. Sun An stood by the handrail and watched, looking satisfied.

This is a trait that can be exploited, although the ability of small lightning to feel vibration is not high, and they can only sense nearby sounds, but this allows them to hunt better, only the small lightning near the ringing animal body will react, and the rest will continue to surge forward, so it will not waste time.

Now that the vacant space in the patio has been filled, and the surface of those models is covered with small lightning bolts, and the electric tide is still flowing, filling the space, Sun An looks quite relaxed now, in fact, the places where he can move are greatly reduced every second.

How to use the characteristic of induced vibration or sound? He was still thinking unhurriedly, there was no point in running now, and the most important thing was to calm down and think about countermeasures.

There was no use for any sound in the mall, the only thing that could be heard was the thunder and the incessant sound of rain outside.

They are not affected by the sound of thunder and rain, and do not hit raindrops.

Sun An knew what he had to do.
