The sharks surrounding us soon began to take action. The smaller big white shark first escaped from the circle surrounding us and swam towards the edge of the little dragon girl. The audience around him began to unconsciously clench his fists and became nervous. [,

The great white shark arrived at Xiaolongnu in just two seconds, and then prepared to launch an attack. What these viewers did not expect was that when the great white shark opened his mouth and was about to bite it, he suddenly shook his tail and swam rapidly towards the distance. Even the other sharks nearby turned around and ran away as if they were frightened by something. In the blink of an eye, they became completely quiet, and all the sharks were trying their best to escape to the distance.

The audience outside are naturally a little confused about this incident, but in fact we are very clear about what happened.

It's actually very simple. Just like dealing with those piranhas just now, we just made some current in the water. However, in fact, the current is much smaller than when dealing with piranhas, so there is no such terrifying arc, it's just a faint current.

Regarding why sharks are scared away by such low voltage... In fact, the reason is very simple. I think sharks have a very good electromagnetic induction ability. Just like dogs cannot tolerate the strong perfume smell, but people don’t react. The reason is that the dog’s nose is too good, so in humans, the dog feels too pungent. By the same token, piranhas cannot sense the current in the water, so we can only use high voltage electricity to directly roast them. But this is not necessary to deal with sharks. Because sharks are very sensitive to electrical signals, the electromagnetic waves with super high power are enough to make them feel uncomfortable and actively avoid them. Even the electromagnetic waves with super high power are still much lower than the voltage that can be directly roasted with piranhas.

Although the audience outside did not understand what was going on, they knew one thing very clearly. That is, the sharks ran away and now they could no longer pose a threat to us.

Without the threat of sharks, we easily broke through this particularly wide water tank. However, although we didn't feel anything, the audience outside finally found the problem.

Those who have noticed time have taken out their watches to check the time, and soon everyone has a rough time to go into the water. So far, we have stayed in the water for fifteen minutes. During this period, we have not been exposed to any air at all. Although we have not had any activities such as fierce fighting underwater, we have been moving after all, and the power required to move underwater is very large. With the amount of exercise like ours, it is absolutely impossible for us to rely on holding our breath to adapt to the underwater environment. Although whales can hold their breath for two hours underwater, the proportion of whales' lungs in the body is extraordinary, so that is not used as our reference. Our lungs are obviously not as large as the proportion of whales' lungs, so we theoretically cannot have too much time to hold our breath than humans.

"They definitely have organs like fish gills." Some viewers said firmly: "It is impossible for normal people to have the ability to hold their breath for such a long time, which is definitely not normal."

"Yes, they must have organs like fish gills."

The audience quickly reached an agreement on their verbal discussions. Because the situation at the scene was too obvious. We had been underwater for more than fifteen minutes, but there was still no reaction of hypoxia. This was definitely not explained by the simple ability to hold our breath.

Just after the audience's discussions became consistent, we also encountered the next isolation door. After passing through this isolation door like the one before, we entered a closed compartment. These compartments are not actually used for drainage, but mainly serve to isolate the water flow between the water tanks on both sides. For example, when we entered the shark section from the piranha section before, the function of the two isolation doors is to reduce the amount of water exchange caused by our back and forth, and the reason is that the water quality on both sides is different.

Piranha is a freshwater fish. The great white shark is inside the sea. The two segmented water just now are freshwater and the other is seawater, so it needs to be isolated. The isolation cabin we are facing now is also used to isolate water, but it not only separates freshwater from seawater, but also has an important role in insulating heat.

When we opened the isolation room... no, it should be said that when I touched the door handle on the other side of the isolation room, I had already discovered the problem. The door handle I held in my hand was very cold, which means that the water temperature behind the door must be very low.

The water temperature in the two sections that just came is around 28 degrees. This temperature is already quite warm. After all, the temperature of water in nature is usually not so high. Although I am not sure about the temperature behind this door for the time being, I guess it is likely to be zero degrees.

Sure enough, when we opened the door here, we immediately felt a biting cold and squeaky water flowing out of the door, and we stepped into the water over the other side and closed the door again in the cold.

The temperature of the water on this side is indeed zero degrees, because there can be obvious thick ice on the top of the water tank above the head. This means that the water temperature here may not even reach zero degrees.

Although the primary school textbook says that the temperature of the ice-water mixture is zero degrees, the premise of this setting is to be under a standard atmospheric pressure environment. The pressure will change the freezing point of the water. If the pressure is high enough, even the temperature is extremely low, the water will not freeze. Of course, the pressure here is not so high that it is just to keep the water temperature here at around minus one degree. Moreover, this temperature is not entirely because of artificial pressure being applied here. More importantly, the water here flows and the speed is quite fast. The water in high-speed flow is difficult to freeze at the same temperature, so the two attributes together create the water environment we are in at minus one degree.

Although the temperature is only one degree lower than ordinary ice water, the temperature here can really kill people in minutes by human standards.

Normal people soak in ice water below 10 degrees without protection, and usually last for no more than 10 minutes. Of course, people who like winter swimming have strong cold resistance and can persist for a while, but that is also something that people gradually exercise. Moreover, normal people must do preparation activities to protect before winter swimming. If you throw the winter swimming champion into the ice water without any preparation, he will not last for a few minutes. Moreover, people who are the first winter swimming can only persist for a short while. Usually, they have to go ashore in a few minutes, otherwise they will be frostbite. The time afterwards needs to be extended a little bit to allow the body to adapt.

Like us, we just suddenly entered the water at 27 or 8 degrees and then the temperature change is not ordinary, and we don’t have the hobby of winter swimming. If a normal person encounters this situation, he will indeed be frozen to death within a few minutes.

However, the above situation is only according to human standards, but has no effect on us. It’s not that we are not afraid of cold. Of course, our cold resistance is indeed much stronger than humans. But the key is that we use electromagnetic control ability to stabilize the layer of molecules on our body surface and keep them at a stable vibration frequency. The essence of temperature is actually the frequency of molecular movement. The more active the molecular movement, the higher the temperature, and low temperature refers to the decrease in molecular movement. Of course, zero does not mean that the molecular movement stops. The state of true molecular movement stops refers to the thermodynamic temperature scale zero. That is, the so-called absolute zero. At this temperature, the molecules will completely stop vibrating, which means that the well-known Brownian movement will completely stop at absolute zero. At this time, the substance will disintegrate and enter the fourth condensed state outside the gas, liquid and solid state.

What we just did was to say that the molecular vibration on the body surface is stable at a fixed frequency, which is equivalent to maintaining the temperature on the body surface. At the same time, because we restrain the vibration of molecules on the body surface and prevent the molecular kinetic energy from being transmitted, our heat loss is very low. In this mode, we do not actually need to consume a lot of energy to fight low temperatures. After all, our way of resisting cold is different from that of humans.

In fact, the reason why humans are frozen to death is mainly due to two types of damage. First, body fluids are frozen; second, chemical reactions are hysteresis.

Low temperatures will cause the liquid to transform into a solid state, which means that various tissue fluids such as blood in the human body will gradually freeze. But in fact, the damage begins before the blood freezes. We all know that blood can transport oxygen, but in fact, there is not only oxygen in the blood. In fact, a large amount of other gases are dissolved in our blood, and the solubility of gas in liquid is directly related to the temperature of the liquid.

When the external temperature is excessive and the body's heat production cannot keep up with the loss of heat, the body temperature will begin to drop. As the blood temperature drops, various gases will begin to precipitate out of the blood vessels. At the same time, not only gases, but chemical substances in various blood will gradually precipitate out, and crystals will appear in the walls of the blood vessels. It is not ice, but chemical crystals such as salt in the blood. When the blood temperature is high, these substances can be dissolved, but after the temperature drops, these things will precipitate out.

The gas separated from the blood will cause the cavity of the blood vessels to appear, and in severe cases it will lead to cardiac arrest. The crystals in the blood will block blood vessels. Moreover, even if these do not occur, the blood that has lost a large amount of chemical lysates has lost its function as the blood, and it can no longer serve as the transport of substances, which means that the human body's circulatory system has stopped working.

If the situation worsens and the blood itself begins to freeze, it will be completely done. Usually, if you don’t get to this group, you will freeze to death first, but there are exceptions, such as local frostbite. Because the body temperature in some areas is too low, the body adjusts itself, the muscles tighten, and the capillaries are closed, which can reduce the speed of heat loss. However, local areas will cut off blood, and then the blood in the blood vessels in this area will coagulate and freeze. Then the frozen blood will expand, spread the blood vessels, causing the blood circulation system to be completely paralyzed, and the surrounding cells will freeze and crack due to low temperatures. Then even if you resume asking questions, the damage has been formed. This is the origin of frostbite.

However, the above situations are mainly caused by rapid temperature de-heating. Usually, the body's cooling will not drop so quickly, so the real reason for people to be frozen to death should actually be the stop of the human chemical reaction.

The human body is a bunch of complex compounds that keep chemical reactions together, which is the essence of life. However, many chemical reactions require a certain temperature. Organisms are very sensitive to temperature changes. For example, when a human body has a fever, the body temperature rises only a few degrees, which can prevent the reproduction of bacteria and viruses in the body. Therefore, fever itself is actually a way for the human body to resist external invasion. As for controlling the temperature of the fever, it is good to protect the brain, because if the fever is too high, it will damage the brain nerves and cause other problems.

A temperature difference of just a few degrees can inhibit bacterial reproduction in large quantities. This shows how sensitive organisms are to temperature. It is better for cold-blooded animals, they have adapted to low temperatures. Constant temperature animals, that is, organisms like humans with constant body temperature, will have problems with their body temperature once their body temperature changes on a large scale.

The main problem caused by low temperature is to slow down the chemical reaction speed. People need energy to live, just like there are many electrical appliances in a huge factory. Every cell in the human body needs energy, and these energy is chemical energy generated by chemical reactions. Low temperature will cause the chemical reaction speed to decrease, and even some chemical reactions will stop completely. Once the chemical reaction in the human body slows down or stops, the cells will lack energy, which will cause the body temperature to drop further, and the situation will continue to deteriorate to form a vicious cycle. Finally, when the human body's chemical reaction speed is reduced to the point where it cannot maintain life, people will die.

Our dragon clan is stronger than humans in this regard, because we are designed as weapons, so the chemical exchange substance used for energy supply in our bodies is a substance that can work at extremely low temperatures. In other words, the low temperature will only reduce our physical energy and will not freeze us to death, or at least it will not be frozen to death because of the stop of chemical reactions. Of course, this low temperature also has a range. When we reach the zero degree of awareness, we have to kneel down.

In addition, there are two essential differences between our dragon cells and human cells. First, there are double mitochondria in our dragon cells, one of which is responsible for chemical reactions, and like humans, converting chemical substances in the cell fluid to provide energy. But we also have another mitochondria, which can also convert chemical energy, but the difference is that it can absorb electricity, heat radiation directly convert energy to provide cell power, and even the above two energy can be reversely used to synthesize energy substances that can be used by ordinary mitochondria. In other words, if our dragons have no food for a long time, charging is also OK. Of course, the voltage must be controlled well, and we are not a complete robot after all. The speed of charging is very slow, it is just an emergency maintenance system, not our main energy supply method.

Second, in addition to the mitochondria, there is also something called a deification factor in the cells of our dragon clan. Of course, this is the name everyone gave, but in fact this thing is the b13 strain.

When the dragon race is transformed, the b13 virus protozoa will first infect the cells, inject RNA, and then regenerate the cells to form dragon cells. After this step is completed, the dragon race DNA in the cells will not completely divide, produce a brand new RNA core, and then automatically generate a protein protective layer to encapsulate it. In this state, it feels like every cell in our dragon race always has a b13 virus strain, but in fact, this strain is always dormant.

So, what is this thing for?

The answer is emergency.

When our dragon tribe dies, the RNA virus will carry the life mark into the state of the virus community. At this time, our individual may die, but our thinking will be uploaded into the dragon tribe's spiritual network. If the spiritual network is disturbed or cannot be uploaded, then our will will be carried by these viruses and saved in the RNA in an archived manner. After that, as long as this uninfectious RNA virus body is found and then specially stimulated, it can use the RNA to reversely restore the DNA information and then copy the entire person again. Of course, this function is confidential. Except for our dragon tribe and a few researchers, there are very few who know this even within the Dragon Tribe.

In addition, in addition to being able to perform emergency records after death, this RNA virus strain also has a function that is to act as a battery.

When our body's internal circulation system does not work for some reasons, causing some areas to be unable to supply energy. These RNA strains will begin to output power in reverse, which can support the body's short-term activity or help repair wounds. These abilities can help us fight low temperatures.
