Chapter 519: Extra Long Body Functions
The group of sharks circling around us soon began to move. One of the smaller great white sharks first broke away from the circle around us and swam towards the little dragon girl at the edge, while the surrounding spectators watched this. Everything also began to unconsciously clenched the fists and became tense.
It only took the great white shark two seconds to reach the little dragon girl, and then he was ready to attack. What the audience didn't expect was that just when the great white shark opened its mouth and was about to bite, it suddenly violently attacked as if it had been stimulated by something. He flicked his tail and swam quickly into 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, the surrounding area became completely quiet. All the sharks were trying their best to move towards Escape from a distance.
The outside audience is naturally a little confused about this turn of events, but in fact we ourselves know very well what happened.
It's actually very simple to say the least. Just like we did with those piranhas just now, we just made some electricity in the water. It's just that the current is actually much smaller than the voltage when dealing with piranhas, so there is no such terrifying arc, just a weak current.
As for why sharks are scared away by such low voltage... the reason is actually very simple. I think sharks have great electromagnetic induction capabilities. Just like dogs can't stand the strong smell of perfume, but people don't react at all. The reason is that dogs have great noses, so dogs find smells that are not strong to humans too pungent. By the same token, piranhas cannot sense current in the water, so we have to use high-voltage electricity to cook them directly. But that's not the case with sharks. Because sharks are very sensitive to electrical signals, ultra-high-power electromagnetic waves are enough to make them feel uncomfortable and actively avoid them. Even ultra-high-power electromagnetic waves are still much lower than the voltage that can directly roast piranhas.
Although the audience outside did not understand what happened, they knew one thing very clearly. That means the sharks have all run away, and now they no longer pose a threat to us.
Without the threat of sharks, we easily passed through this particularly large water tank. However, although we didn't feel anything, the spectators outside finally discovered the problem.
Those who had paid attention to the time before now took out their watches to check the time, and soon everyone came up with an approximate time for us to enter the water. We had been in the water for a full fifteen minutes now. And during this time we were not exposed to any air at all. Although we don't have any activities like fierce fighting underwater, we are always moving after all, and moving underwater requires a lot of strength. With the amount of exercise we do, it is absolutely impossible to rely on breath-holding to adapt to the underwater environment. Although whales can hold their breath underwater for two hours, the proportion of whale lungs to the body is unusually large, so that cannot be used as a reference for us. Our lungs are obviously not proportionally larger than those of whales, so we theoretically cannot hold our breath much longer 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. This is definitely not a normal situation."
"Yes, they must have organs like fish gills."
The audience quickly reached a consensus because the situation at the scene was too obvious. We have been underwater for more than fifteen minutes, and there is still no reaction of hypoxia. This is definitely not something that can be explained by simple breath-holding ability.
Just after the audience's comments became unanimous. We also encountered the next isolation door, and after passing through this isolation door like the previous one, 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, the function of the two isolation doors was to reduce the amount of water exchange caused by us traveling back and forth. The reason is that the water quality on both sides is different.
Piranha is a freshwater fish, while great white sharks are from the sea. The water in the two sections just now is fresh water and the other is sea water, so it needs to be isolated. The isolation cabin we are facing now is also used to isolate water, but it not only isolates fresh water and sea water. The more important function is heat insulation.
When we opened the isolation room... no, I should say I discovered the problem when I touched the door handle on the other side of the isolation room. The doorknob I was holding was very cold, which meant the water behind the door must be very cold.
The water temperature in the two sections we just came over is around 28 degrees, which is quite warm. After all, the temperature of water in nature is usually not so high. Although I'm not sure for the moment about the temperature behind this door, I guess it's probably zero degrees.
Sure enough, when we opened the door here, we immediately felt a burst of cold and biting water flowing out of the door, and we braved the cold and stepped into the water over there to close the door again.
The temperature of the water on this side is indeed zero degrees, because an obvious thick layer of ice can be seen on the top of the water tank overhead, which indicates that the water temperature here may not even be below zero degrees.
Although primary school textbooks say that the temperature of the ice-water mixture is zero degrees, this setting is based on a standard atmospheric pressure environment. Pressure changes the freezing point of water, and if the pressure is high enough, even extremely cold water will not freeze. Of course, the pressure here is not so ridiculously high. It only keeps the water temperature here at about minus one degree. And this temperature is not entirely due to the artificial pressure exerted here. More importantly, the water here is It's flowing, and it's pretty fast. Water flowing at high speeds is more difficult to freeze at the same temperature, so these two properties combine to create the sub-zero degree water environment we live in.
Although the temperature is only one degree lower than ordinary ice water, by human standards, the temperature here can really kill someone in minutes.
Normal people can soak in ice water below 10 degrees without protection for no more than 10 minutes. Of course, people who like winter swimming have stronger cold tolerance and can persist for a longer period of time, but that is something people gradually develop. And normal people do preparatory activities for protection before winter swimming. If you suddenly threw a winter swimming champion into ice water without any preparation, he wouldn't be able to last a few minutes. And people who are swimming in winter for the first time can only last for a short while. It usually only takes a few minutes to get ashore, otherwise you will get frostbite. The time after that needs to be extended a little bit to allow the human body to adapt.
Like us, we just suddenly entered the water from 27 or 8 degrees Celsius to the water of minus one degree. This temperature change is not ordinary, and we do not have the hobby of winter swimming. If normal people encounter this situation. It would literally freeze to death within a few minutes.
However, the above situation is only based on human standards and has no impact on us at all. It’s not that we are not afraid of the cold. Of course, our cold tolerance is indeed much stronger than that of humans, but the key is that we use electromagnetic control capabilities to stabilize the layer of molecules on our body surface and maintain it at a stable vibration frequency. The essence of temperature is actually the frequency of molecular motion. The more active the molecular motion, the higher the temperature. Low temperature means that molecular motion is reduced. Of course, zero does not mean that molecular motion has stopped. The state where molecular motion truly stops refers to zero on the thermodynamic temperature scale, which is the so-called absolute zero. At this temperature, the molecules will completely stop vibrating. The well-known Brownian motion will completely stop at absolute zero, and at this time the material will disintegrate. And enter the fourth state besides gaseous, liquid and solid states - condensed state.
What we have just done is to stabilize the molecular vibrations on the body surface at a fixed frequency, which is equivalent to maintaining the temperature of the body surface. At the same time, because we have restrained the vibrations of molecules on the body surface, the kinetic energy of the molecules is no longer transmitted. So our heat loss is very low. In this mode, we actually do not need to consume a lot of energy to fight against low temperatures. After all, the way we resist cold is different from the way humans resist cold.
In fact, humans freeze to death. There are mainly two types of damage. First, body fluids freeze; second, chemical reactions stagnate.
Low temperature will transform liquid into a solid state, which means that blood and other tissue fluids in the human body will gradually freeze. But the damage actually begins before the blood freezes. it is known. Blood can transport oxygen, but it is not actually only oxygen in blood. There are actually a large number of other gases dissolved in our blood, and the solubility of gases in liquids 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 heat loss, the body temperature will begin to drop. As the blood temperature drops, the blood in the blood vessels will begin to precipitate various gases. At the same time, not only gases, but also various blood The chemicals in the blood will gradually precipitate, and crystals will appear in the blood vessel walls. They are not ice, but chemical crystals such as salt in the blood. These substances can be dissolved when the blood temperature is high, but they will precipitate when the temperature drops.
The gas separated from the blood can cause cavities in blood vessels, which can lead to cardiac arrest in severe cases. Crystals in the blood can clog blood vessels. And, even if none of this happens. The blood itself, which has lost a large amount of chemical dissolved substances, has lost its function as blood. It can no longer transport substances, which means that the human body's circulatory system has stopped working.
If things get worse and the blood itself starts to freeze, it's all over. Usually people freeze to death before reaching this part, but there are exceptions, such as localized frostbite. Because the body temperature in certain areas is too low, the human body adjusts itself, tightens muscles, and closes capillaries. This can reduce the rate of heat loss, but the local area will cut off blood, and then the blood in the blood vessels in this area will coagulate and freeze, and then freeze. The blood will swell and open the blood vessels, causing the blood circulation system to be completely paralyzed. The surrounding cells will also freeze and crack due to the low temperature. Then even if you resume questioning, the damage has already occurred. This is the origin of frostbite.
However, the above situations are mainly the result of rapid hypothermia. Normally, the human body does not cool down that quickly, so the real cause of people freezing to death should actually be the cessation of chemical reactions in the human body.
The human body is a bunch of complex compounds that are constantly undergoing chemical reactions. This is the essence of life. However, many chemical reactions require a certain temperature. Organisms are very sensitive to temperature changes. For example, when the human body has a fever, the body temperature only rises by 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 fever temperature, it is just to protect the brain, because if the temperature is too high, it will damage the brain nerves and cause other problems.
A temperature difference of just a few degrees can significantly inhibit bacterial growth. This shows how sensitive organisms are to temperature. Cold-blooded animals are better off because they have adapted to low temperatures. However, for warm-blooded animals, which are creatures with a constant body temperature like humans, once their body temperature changes in a large scale, chemical reactions in the body will go wrong.
The main trouble caused by low temperatures is that they slow down chemical reactions. People consume energy to live, just like there are many electrical appliances in a huge factory. Every cell in the human body needs energy, and all of this energy relies on chemical energy generated by chemical reactions. Low temperature will cause the speed of chemical reactions to slow down, and even some chemical reactions will stop completely. Once the chemical reactions in the human body slow down or stop, the cells will lack energy. This will then cause the body temperature to drop further, and then the situation will continue to worsen, forming a vicious cycle. Finally, when the body's chemical reaction speed slows down to the point where it cannot sustain life, the person will die.
We dragons are better than humans in this regard, because we ourselves are designed as weapons. Therefore, the chemical exchange substance used to supply energy in our body is a substance that can work at extremely low temperatures. In other words, low temperature will only reduce our physical energy and will not freeze us to death, at least not because the chemical reaction stops. Frozen to death. certainly. This low temperature also has a range, and we have to kneel even when it reaches zero degrees.
in addition. There are two essential differences between our dragon cells and human cells. First, we dragons have double mitochondria in our cells, one of which is responsible for chemical reactions, just like humans. Converts chemicals in cell fluids to provide energy. But we also have another mitochondria. This mitochondria can also convert chemical energy, but it is different from the other one in that it can absorb electrical energy and thermal radiation and directly convert energy to provide cell power. It can even use the above two kinds of energy in reverse for synthesis. Energy substances that can be utilized by ordinary mitochondria. In other words, if we dragons are without food for a long time, it is still possible to recharge. Of course, the voltage must be controlled well, and we are not complete robots after all. The charging speed is very slow. It is just an emergency maintenance system, not our main energy supply method.
Secondly, in addition to the mitochondria, there is something called a deification factor in our dragon cells. Of course, this is the name given by everyone, but in fact this thing is the B13 strain.
When dragon transformation is performed, the B13 virus will first infect the cells, then inject RNA, and then regenerate the cells to form dragon cells. When this step is completed, the dragon DNA in the cell will undergo incomplete division to produce a new RNA core, and then automatically generate a protein protective layer to encapsulate it. In this state, it feels like every cell of our dragon family always has a B13 virus strain, but in fact this strain is always dormant.
So, what does this thing do?
The answer is - emergency.
When our dragon family dies, the RNA virus will carry the mark of life and enter the virus community state. At this time, our individual may die, but our thoughts will be uploaded into the dragon family's spiritual network. If the spiritual network is interfered with or other reasons prevent the upload, Then our will will be carried by these viruses and stored in the RNA in an archived manner. After that, as long as this non-infectious RNA virus is found and given special stimulation, it can use RNA to reversely restore DNA information and then replicate the entire person again. Of course, this function is confidential. Except for us, the Dragon Clan, and a few researchers, there are very few people even within Long Yuan who know about this matter.
In addition, in addition to serving as an emergency recorder after death, this RNA virus strain also has another function - acting as a battery.
When our body's internal circulatory system does not work for some reason, 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 activities for a short period of time or help repair wounds. These abilities allow us to combat cold temperatures.
Of course, we still don't like the cold, so we use electromagnetic control to seal off the molecules around the body instead of using the body's resistance to fight against low temperatures. (To be continued ~^~)
