Chapter 124 To make a decision or not
The gradually warming body made Du Jin's senses become active again. At this time, he seemed to be able to move his body slightly. He lowered his head towards his limbs and discovered the fleshy membranes attached to his body. It was as if he was breathing. At the same time, he could also perceive a state of "connection", as if these creepy-looking objects were a part of him and were in the same frequency state as all his activities. Rather than acting as a tool to restrain yourself.
"This is............."
Although Du Jin had some worries and worries in his heart, this rebirth-like experience made him instinctively force himself to accept everything in front of him, because he knew that the reason why he was now being "protected" by this unknown organism was probably related to his body. The black blood mark that has absorbed the "life" of the corpse is inseparable. As for the secrets and reasons, it is not something Du Jin can explore at this time. Of course, forced exploration is also possible, but the price may be real death. , or a second similar reincarnation, but no matter what, Du Jin wants to seize every opportunity to return to reality, rather than sacrifice for the so-called truth.
After he sorted out his thoughts, Du Jin mustered up the courage to slowly turn his head back. He wanted to find a way out of here instead of waiting all the time. The last time Du Jin left was because Li Mengyan found him a knowledge transfer The device completed the transmission program. At that time, he only knew that this place was called the "Blood Moon Dimension" and was forcibly extracted from this place. But this time, Du Jin was in reality due to excessive blood loss and severe physical injuries. He fainted due to various reasons, and his consciousness returned here again.
According to a series of observations before Du Jin's consciousness was forcibly pulled back into the body, his injuries at the time were almost fatal under modern medical technology. Not to mention the irreversible brain damage caused by blood loss, let's talk about the body surface temperature. The organ failure caused by the low core temperature in the body almost put Du Jin on the verge of death.
(Humans are endothermic animals, with a constant body temperature between 36°C and 37°C. I believe many people have no objection to this, but many people may not know that the temperature of the human body actually has two different concepts: surface temperature & core body temperature.
The core body temperature of the human body generally refers to the body temperature inside the human body, but objectively speaking, it should be understood as the temperature of the hypothalamus. This temperature is a very narrow temperature range. Once it exceeds or falls below this temperature, it will affect the human body. Survival is a threat, so the human body will regulate temperature through a very complete thermostatic mechanism.
Generally speaking, the range of normal core body temperature is only 0.3℃, usually around 37.2---37..5℃, and all the body's body temperature regulation methods include but are not limited to: goose bumps, chills, sweating, Body surface redness, syncope, shock, etc. are all reactions based on the body's core temperature. The human body surface temperature, as the name suggests, is the temperature measured on the human body surface.
This temperature actually spans a very wide range. Even under the same external temperature, the measured temperatures on the human body surface are very different. Theoretically, the local body surface temperature of the human body can fluctuate between 10°C and 60°C. The average body surface temperature is approximately between 20 and 30°C. In extreme cold conditions, the local body surface temperature of the human body can even be as low as 5℃, while in a sauna, especially a dry sauna, the human body surface temperature can be as high as 60℃. For the human body's cooling system, the role played by the body surface can be compared to the heat sink of an air conditioner. The role of the blood circulation system in the human body's constant temperature system is actually more similar to the air conditioning compressor-refrigerant circulation system.
In general, the heat dissipation mechanism of the human body is roughly as follows:
1. The heat generated inside the human body is brought to the superficial surface through the blood circulation system, and is dissipated through the skin, superficial tissues and lungs (you can Baidu on the principle of heat dissipation, it is nothing more than cold air flowing through hot surfaces to take away heat. routine, and sweating only uses the evaporation principle of water to intensify heat dissipation). At the same time, the condensed blood after heat dissipation is pumped by the heart to major tissues and the brain. While transporting oxygen, it takes away the heat of various organs and circulates to the body surface for heat dissipation. .
2. When the external temperature is high and is not conducive to body surface heat dissipation, the flow rate and flow rate of end blood vessels on the surface of the human body will be accelerated by diffusing capillaries, accelerating heart rate, etc., and utilizing the principle of "small profits but quick turnover" for heat exchange .
3. When the external temperature is too high and the capillaries are expanded and the blood flow is accelerated and it is not enough to maintain heat dissipation, sweating and interstitial fluid will be discharged to accelerate body surface heat dissipation, and at the same time, the water content in the blood will be used. Interstitial fluid replenishment. Therefore, one thing needs to be made clear here: what the human body sweats is not actually the water in the blood, but the water contained in the interstitial fluid.
4. When the outside temperature is too low, the body will not only shrink capillaries and reduce the blood flow rate on the body surface, but also raise hairs (commonly known as goosebumps), blocking the airflow through the body surface through hairs. speed, thereby slowing down the efficiency of the airflow in taking away temperature to further reduce heat dissipation.
5. Since human cells require oxygen, although human muscle tissue and fat cells have a high tolerance to hypoxia, they are not able to survive without oxygen. Therefore, the human body’s protective mechanism does not allow the human body to completely block superficial capillaries. After the body surface temperature is low enough to threaten the core temperature and lasts for a period of time, the human body will spontaneously discharge interstitial fluid, further lowering the body surface temperature and forcing the superficial tissue to further shrink due to cold. The contracted tissue presses the capillaries to further narrow, extremely Greatly reduce the flow rate of blood on the body surface, thereby maximizing the core temperature protection - this is cold sweat.
6. When the outside temperature is extremely low, in addition to cold sweat, the hypothalamus will also issue instructions to cause the human muscles to contract rhythmically, increase glucose consumption, and generate a large amount of heat. These muscle contractions will be produced through blood circulation. The heat is brought into the core of the body to further protect the core temperature - this is shivering. (In fact, many people have never really shivered. Real chills are completely uncontrollable and violent shivers, and real chills only occur in extremely cold environments that may be life-threatening. Normally, The shivering caused by the cold is just a conditioned reflex of the muscles. It can be stopped with a little control. By the way, many friends who don't believe it can try to hold on after soaking in the swimming pool for more than three hours in autumn or at night. The edge of the pool was shaking like chaff, and it was impossible and uncontrollable to even hold on to the edge of the pool to climb ashore. That was a real chill.)
But Du Jin began to clearly remember that when he finally steeled himself to escape from the attack range of the Necromorph, there was no cold sweat on his body. This showed that his body was almost on the verge of collapse at that time. ! Perhaps it has completely collapsed, and even the most basic heat maintenance has lost its effect.
But even now Du Jin has no regrets about his behavior of luring the "lone wolf" away, especially when he saw the "lone wolf" mutate into a corpse in front of his own eyes. At that time, Du Jin felt Apart from fear, the only thing left is happiness. If this thing directly mutates on the street, no matter from any angle, it will be a huge blow to mankind and the Xia Kingdom, even if Du Jin does not want to save the entire world of mankind. Great man, but at least he has to think about his country.
If this thing is made public, according to the habits of those capitalist countries, they will crazyly advocate the threat theory of Xia Kingdom, and join forces with other countries to attempt to conduct large-scale investigations and evidence collection against Xia Kingdom, and on this issue of possible annihilation of mankind , the original struggle in the political field is likely to evolve into a war due to various issues such as sovereignty. At that time, humans may die in the hands of their own weapons before the blood mark begins to be infected on a large scale. At that time, Du Jin is most worried and most A sight I don’t want to see.
Therefore, although he felt unwilling to die, he still had no regrets. Thinking of this, Du Jin sighed, but then when his eyes were about to see behind him, Du Jin immediately felt a similar An object in human hands pressed against the back of his head, abruptly stopping his tendency to turn his head.
Although the touch was somewhat similar to the five fingers of human beings, Du Jin did not feel any heat. All he could feel was the bone-deep cold. This made him shiver as he had restored heat due to the protection of the fleshy membrane. Trembling, it was obvious that no matter who he was talking to before, the unknown creature did not want Du Jin to see his face or form. Du Jin immediately dispelled all curiosity in his heart and wanted to explain himself. He didn't mean any trouble, but this time the other party exceeded Du Jin's expectations and said to Du Jin in a very stiff and low voice:
"You...shouldn't exist...here, your race...shouldn't exist... ...Step into the abyss, your .....choice ... ...is correct and fails.”
Du Jin didn't know how to respond to this typical Riddler statement. Race? Du Jin first thought of human beings, but the other party was referring to human beings in this world or in the blood-stamped world. What was most puzzling to Du Jin was what the "choice" was. wolf" behavior, that............
"Wait...how does it know this?"
Du Jin seemed to suddenly realize something. The unknown creature behind him might be able to directly view his memory, which is a traditional mind-reading method. Or, the other party could directly observe from his own perspective, or some kind of God's perspective. Notice every move you make?
