Chapter 124: Choice 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 looked down at his limbs at this time, and found that the flesh membranes attached to his body seemed to be breathing, and at the same time, he could also perceive a state of "connection", as if these creepy looking objects were part of himself, in a state of the same frequency as all his activities, rather than acting as a tool to bind himself.

"It's ............."

Although Du Jin had some worries and concerns in his heart, this general experience of rebirth made him instinctively force himself to accept everything in front of him, because he knew that the reason why he was "sheltered" by this unknown organism now was probably inseparable from the black blood mark that absorbed the "life" of the corpse mutant in his body, as for the secrets and reasons for it, it was not something that Du Jin could explore at this time, of course, it was okay to forcibly explore, but the price was probably real death, or a second similar reincarnation, but no matter what, Du Jindu 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 plucked up the courage to turn his head backwards slowly, he wanted to find a way out of here, instead of waiting, the last time Du Jin left because Li Mengyan found him a knowledge transfer device to complete the transmission program, at that time he just knew that this place was called the "Blood Moon Dimension", and he was forced to leave here, but this time, Du Jin passed out because of excessive blood loss and serious damage to his body in reality, and his consciousness returned here.

According to a series of observations before Du Jin's consciousness was forcibly pulled back into his body, with his injuries at that time, he was almost certain to die under the medical technology of the present world, not to mention the irreversible damage to the brain caused by blood loss, but also the organ failure caused by the low body surface temperature and core temperature in the body, which almost drew a death stop for Du Jin.

(Human beings are homeothermic animals, and the body temperature is constant between 36 °C ~ 37 °C, which I believe many people have no objection to, but many people may not know that there are actually two different concepts of human body temperature: body surface temperature & core body temperature.)

The core body temperature of the human body, generally speaking, 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 pose a threat to the survival of the person, so the human body will regulate the temperature through a very complete thermostatic mechanism.

In general, the normal core body temperature ranges from 0.3°C, usually between 37.2---37. Around 5°C, and all the ways of thermoregulation of the human body, including but not limited to: goosebumps, chills, sweating, redness on the body surface, syncope, shock, etc., are all based on the reaction of the core temperature of the human body. The skin temperature of the human body, as the name suggests, is the temperature measured on the surface of the human body.

Theoretically, the local body surface temperature of the human body can fluctuate between 10 °C ~ 60 °C, and the average body surface temperature is about 20 ~ 30 °C. In extreme cold, the local body surface temperature can even be as low as 5 ° C, while in the sauna, especially in the dry sauna, the human body surface temperature can be as high as 60 ° C. For the human body cooling system, the role played by the body surface can be compared to the heat sink of the air conditioner. The role of the blood circulation system in the constant temperature system of the human body is actually more similar to the circulation system of the air conditioning compressor - the refrigerant.

In general, the heat dissipation mechanism of the human body is roughly as follows:

1. Bring the heat generated inside the human body to the superficial surface through the blood circulation system, and dissipate heat through the skin, superficial tissues and lungs (the principle of heat dissipation can be Baidu by yourself, which is nothing more than the routine of cold air flowing through the hot surface to take away the heat, and sweating only uses the principle of water evaporation to intensify the heat dissipation), and at the same time, the condensed blood after heat dissipation is pumped by the heart to the major tissues and brains, transporting oxygen at the same time, taking away the heat of various organs, and circulating to the body surface for heat dissipation.

2. In the case that the high external temperature is not conducive to the heat dissipation of the body surface, the flow rate and flow rate of the terminal blood vessels in the superficial surface of the human body will be accelerated by diffusion of capillaries, acceleration of heart rate, etc., and the principle of "small profits but quick turnover" will be used for heat exchange.

3. When the external temperature is too high, expanding capillaries and accelerating blood flow is not enough to maintain heat dissipation, the body surface heat dissipation will be accelerated by sweating and by excreting interstitial fluid, and the water content in the blood will be used to replenish interstitial fluid. Therefore, it needs to be clear here: the human body sweats not the water in the blood, but the water contained in the interstitial fluid.

4. In the case of low outside temperature, the body will shrink capillaries and reduce the speed of blood flow on the body surface, and will also erect hair (commonly known as goosebumps), which will block the speed of air flow through the body surface through hair hair, thereby slowing down the efficiency of air flow away from temperature to further reduce heat dissipation.

5. Because human cells must be oxygen, although the hypoxia tolerance of human muscle tissue and fat cells is very high, it is not enough to reach the point of oxygen cut-off survival, so the human body protection mechanism does not allow the human body to completely block the superficial capillaries, and 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 reducing the body surface temperature and forcing the superficial tissues to further shrink due to cold, and the contracted tissues compress the capillaries to further narrow. Dramatically reduces the flow of blood on the surface of the body, thereby maximizing the core temperature – this is known as cold sweating.

6. In the case of a particularly low outside temperature, in addition to cold sweat, the hypothalamus will also send instructions to make the human muscles contract rhythmically, increase glucose consumption at the same time, produce a large amount of heat, and bring the heat generated by these muscle contractions into the core of the human body through blood circulation, so as to further ensure the core temperature - this is shivering. (Actually, many people haven't really shivered.) The real cold tremor is completely uncontrollable, more violent trembling, and the real cold tremor will only occur in an environment that is extremely cold to the point that it may be life-threatening, and the cold tremor that usually occurs because of the cold is just a conditioned reflex of the muscles, which can be stopped as long as it is slightly controlled - by the way, many unbelieving friends can try to soak in the pool for more than three hours in the autumn and at night, and the edge of the pool is shaking like chaff, and it is impossible and impossible to control the feeling of climbing to the shore by the pool, That's the real chill. ）

But Du Jin began to remember clearly that when he finally pulled himself up and wanted to escape from the attack range of the corpse mutant, there was no cold sweat on his body, which showed that his body at that time was almost on the verge of collapse, no! Perhaps it has completely collapsed, and even the most basic caloric maintenance has lost its effect.

But for his behavior of luring away the "lone wolf", even now Du Jin has no regrets, especially when he saw the "lone wolf" mutated into a corpse mutation in front of his eyes, at that time Du Jin was not only afraid in his heart, but the rest was lucky, if this thing mutated directly on the street, then no matter what point of view, it would be a very huge blow to mankind and Xia Guo, even if Du Jin was not a great man who wanted to save the whole world, but at least he had to think about his motherland.

If this thing is made public, according to the habits of those capitalist countries, they will frantically advocate the threat theory of the Xia Kingdom, and unite with other countries to attempt to conduct a large-scale investigation and evidence collection of the Xia Kingdom, and on this possible extinction of human beings, the original struggle in the political field is likely to turn into a war because of various issues such as sovereignty, and then human beings may die in the hands of their own weapons before the blood seal begins to infect on a large scale, and Du Jin is the scene that Du Jin is most worried about and least willing to see.

Therefore, although he felt unwilling to die at his death, he still did not regret it, thinking of this, Du Jin sighed, but then when his eyes were about to see behind him, Du Jin immediately felt an object similar to a human hand against the back of his head, and forcibly stopped his tendency to turn his head.

Although the touch is somewhat similar to the five fingers of a human being, Du Jin didn't feel any heat, only the bone-chilling cold, which made him, who had recovered the heat because of the protection of the flesh membrane, couldn't help but shiver, obviously, no matter who he was talking to before, the unknown creature didn't want Du Jin to see his face, or the form, Du Jin immediately dispelled all the curiosity in his heart, and wanted to explain that he didn't mean to be in trouble, but this time the other party exceeded Du Jin's expectations, In a very stiff and deep voice, he said to Du Jin:

"You............. There shouldn't be ............. Here, your race.......... No........ Step into the abyss, your .......... Choice......... Correct and fail. ”

This typical riddler's speech made Du Jin not know how to respond for a while, race? Du Jin first thought of human beings, but what the other party was referring to was the human beings in the current world, or the human beings in the blood seal world, and what made Du Jin feel most puzzling was what the "choice" was, if the other party was referring to his behavior of leading away the "lone wolf", then ...............

"Wait................ How does it know this? ”

Du Jin seems to have suddenly realized something, the unknown creature behind him, I am afraid that he can directly check his memory, that is, the traditional level of mind reading, or the other party can directly observe his every move from his own perspective, or from the perspective of some kind of God?
