[Chapter 171] Backlash Just when Du Jin was about to pounce on the red blood mark, Du Jin suddenly felt a strong sense of foreign body invading his chest. This felt familiar and unfamiliar at the same time, but No matter what, he immediately realized that this was not a good sign, but that the necromorph behind him had caught up with him, and had even inserted the bone blade alien limb that was as sharp as clay into his chest. The only thing worth mentioning was that Du Jin was fortunate that he felt this foreign body sensation on his right side, not on his heart, which could kill him with one blow.
Generally speaking, when the chest cavity is penetrated, the negative pressure in the chest cavity is destroyed, which subsequently causes the alveoli to be unable to inhale air, leading to suffocation. However, during the penetration, there is no pain as imagined.
But then Du Jin began to regret why it was not his heart that was stabbed. Every breath he took now caused severe pain in his chest. He wanted to move his hands, but found that only his fingers could barely move; he wanted to make a sound. , but only blood foam can be spit out from his mouth, and a dying sob comes from his throat that frightens him. You can't breathe or struggle. It feels like your whole body is gradually drowning in blood, and then you gradually lose your hearing like a nightmare. Vision and Thought….
. . . . . . . . . . . …. . . . . . . Du Jin is no stranger to this similar process, because he has experienced it personally before. At this moment, he just feels the burning pain when breathing, and can imagine the symptoms that will happen next, and last time he was accompanied by There is also shock caused by massive bleeding, but strictly speaking, neither thoracic puncture nor hemorrhagic shock is an instant death. Puncture will cause the pleural cavity to directly communicate with the outside atmosphere, and air can flow freely into the pleural cavity with breathing. , forming an open pneumothorax, the pleural cavity on the contralateral side is still negative, lower than the injured side, causing the mediastinum to shift toward the contralateral side, which will cause the contralateral lung to collapse to a certain extent.
At the same time, because in this case, the thoracic pressure on the unaffected side can still increase or decrease with the respiratory cycle, causing mediastinal swing and residual air convection, leading to severe ventilation and ventilation dysfunction.
The swing of the mediastinum causes the great blood vessels of the heart to twist back and forth and damage the negative pressure in the thoracic cavity, which blocks the return of venous blood and reduces cardiac output. However, the time from asphyxia to death is generally within tens of minutes.
As for death from blood loss, Du Jin can be said to have a deep understanding of it. At that time, when his body was getting colder and his vision was getting blurry, he witnessed
The "lone wolf" mutates in front of his eyes. The specific process is that when insufficient blood volume exceeds the compensatory function, shock syndrome will occur, tissue perfusion will be reduced, and anaerobic metabolism will occur, leading to an increase in blood lactic acid content and metabolism. acidosis, and then blood flow is redistributed so that the blood supply to the brain and heart can be maintained.
At this time, further contraction of blood vessels will cause cell damage. Damage to vascular endothelial cells leads to loss of body fluids and proteins, aggravating hypovolemia, and eventually multiple organ failure. Of course, the time from severe trauma to death generally ranges from minutes to hours, depending on the condition of the injured blood vessels. importance, that is, looking at
"Luck", if it is veins or other parts with not dense blood vessels, this process can be relatively prolonged, but if it is the heart, liver and kidneys, or the carotid artery is unlucky like Du Jin last time, then this time will be reduced sharply to It could be two or three minutes, or even one minute.
But what really scares Du Jin is that with his attitude towards
Those necromorphs on the Eden
"Observe", the usual method used by these monsters is laceration, which is much better than simple
"Cut" a knife
"Going away at a touch" is much more serious, so he has a strong premonition that the corpse with six alien limbs behind him will probably tear himself in half with the remaining alien limbs. Of course , Du Jin's body can be strengthened and cannot be as fragile as ordinary people, even if it is torn apart by the corpse.
. . . . . . . . . . . . . . . Well, at least it can guarantee that it won't be torn from the middle, leaving only a big hole in the chest. Although the results are similar, it is obvious that Du Jin has the advantage of convenient autopsy and recovery of the body afterwards.
. . . . . . . . . . . . . . . . . . . . . .
"No! There's only one step left, a little distance, as long as I get closer!" Du Jin gritted his teeth. The torture caused by his breathing at this moment caused a big gap in his thoughts, but he kept one thing in mind. That is to say, Xingying and the girl named Xiaoyou must be sent out. After all, he still has the protection and trump card of the black blood seal, and the only person the mother and son can rely on now is him. Du Jin doesn't hesitate when he thinks of this. Using the nerve acceleration ability given to him by the black blood seal, everything in front of him suddenly slowed down from Du Jin's perspective, but it was accompanied by an increasingly severe pain.
"I'll do it! I almost forgot, my reaction speed is faster, doesn't the wound bring me more pain?!" After all, the ability of neural acceleration does not stop time, it just makes Du Jin subjectively more agile , from the outside world, Du Jin is also moving, but the moving speed is much faster than he usually does. As for the stimulation signal transmitted in the nervous system, that is, the pain sensation, it will naturally move at a faster rate. The speed and greater stimulation reached Du Jin's nerve endings. The sudden feeling of suffocation made him almost roll his eyes, but fortunately, he had just experienced it.
He is a "big world" person. Although this kind of pain is unbearable, it will not trigger his
"The body's bottom line of protection" fainted. After all, from a biological mechanism point of view, people are usually triggered when they are frightened, cannot bear the pain, or have particularly strong feelings. At this time, the brain will activate a self-protection mechanism - that is, fainting or syncope. This mechanism The purpose is to "no longer allow us to be hurt or endure particularly strong emotions." The subsequent awakening is because our brains are divided into two consciousnesses.
One is the "conscious mind" and the other is the "subconscious mind". This is because we simply do not have a "conscious mind", while the "subconscious mind" is still awake, and it controls when we wake up. Generally, when When our emotions weaken, the "subconscious mind" will wake us up~ Of course, in Du Jin's case, if this protection is triggered, it will only make Du Jin die faster.
But even so, Du Jin can make some preparations to break the situation before the zombies behind him start to tear him apart, that is, to accumulate energy for his next momentum. To be precise, the body's energy accumulation is not enough. Yes, the energy storage of muscles and springs is not the same. Human muscles are different from springs. Spring compression or elongation can store a lot of energy, but muscles cannot. If you close your fists or legs hard and then relax , will the fingers, arms and body bounce away?
Not really. What Du Jin uses is the tension caused by the different degrees of deformation of human muscles. People retract their arms before punching and bend their knees before running, so that the body can contract, retract, and retract in a short period of time before exerting force. Movement, this is more about contracting the muscles to give them longer room for deformation. This is like a person doing a long jump, a 5-meter run-up and a 10-meter run-up. The results are obviously different.
Of course, the simplest explanation is to increase the acceleration distance. Uniformly accelerated linear motion starts from rest. The square of the terminal velocity is equal to twice the product of acceleration and the acceleration distance. Therefore, the greater the acceleration distance, the greater the terminal velocity. This is why it moves slightly backward, although it is actually faster than the uniform acceleration. The model of linear motion is much more complicated, but it can also be understood qualitatively.
He leaned forward with the help of a foot that was already on the ground. Du Jin immediately felt a pulling sensation in his chest, as if something was being forcibly pulled out of his body, and this process It’s definitely not good. There are obviously tiger tongue-like features on the necromorph’s alien limbs.
"Saw", Du Jin roared in his heart
"A long-term pain is not as good as a short-term pain." Then he used his leg muscles to exert force, and then quickly stepped out the other leg and squatted half-squat, and his arms also moved from the beginning.
The "embrace shape" became a swing shape with a difference in height up and down. Previously, Du Jin wanted to hug the red blood mark directly and engage it with the largest body contact area.
"Fusion" can also ensure that the black blood mark can counterattack as soon as possible, but now Du Jin can only choose to hit the top to contact the red blood mark before being dismembered by the corpse. When he is ready for everything, the contact ability will have side effects. He touched the blood-stamped statue as soon as possible before appearing, but when he raised his head, he discovered that the runes floating on the surface of the blood-stamped statue in front of him did not slow down under Du Jin's accelerated senses, and still maintained a certain frequency as before.
"How is this... The blood mark is directly mapped in my mind? Otherwise, as long as it exists in reality, it must also be under my accelerated senses. Will there be changes?" Theoretically speaking, human senses also limit the speed of observation. For example, the objects under observation are in the process of constant movement and change. Some objects change faster, and some objects change faster. Slower, so when people observe these objects through their senses, they need their senses to have a certain observation speed.
However, the speed of observation of the senses is limited. For example, the human eye cannot distinguish the shape of an object passing by at high speed.
For objects whose movement changes extremely slowly, human senses cannot observe the movement changes.
As for the changes in human beings, they have developed from direct observation with the senses to observation through instruments as an intermediary. This is a fundamentally significant change in the observation method. Of course, this is all for another day, at least for today's people. It makes no sense to Du Jin.
. . . . . . . . . . . . . . . . . . . . . . . . . . Obviously, if the red blood mark itself did not have a certain synchronic relationship with Du Jin's nervous system, it was because a similar impression was implanted in Du Jin's subconscious. At this time, Du Jin immediately realized that he had just entered The room was forcibly controlled by a red blood seal. Although he was not directly mentally dominated or controlled, it still left some subtle effects.
"The black blood mark in my body cannot completely resist the erosion of the red blood mark? Is it because there is a fundamental difference between the two, or is it because the black blood mark has not recovered or gained enough strength?" Du Jin's thoughts seemed to be distracted by the statue in front of him. Captured, he looked at the runes that appeared according to rules, and some inexplicable emotions appeared in his mind, which made him feel that the red blood seal was leaning toward joy and stability.
"It seems" that as long as humans have doubts or concerns about something, they will hesitate, and
The theory "hesitation leads to defeat" is not just a
"rumor". But at this moment, the slightly hesitant look on Du Jin's face was replaced by a relieved smile. The blood seal may not have thought of Du Jin's psychological activities at this time, because it has forgotten the fact that human beings really only need to deal with If you have doubts or concerns about something, you will hesitate. But if it is life-threatening and you have to fight between trapped animals, these concerns will not become an obstacle, but will become a push to force the person in trouble to resist.
"Since the black blood seal has not recovered or gained enough strength, after swallowing this red blood seal, even if it is not a physical statue in reality, it should still be a spiritual differentiation of the real blood seal within the Unity Church. I don't believe it. The black blood mark didn't help at all." Then Du Jin was no longer trapped by any hesitation in his feet and thoughts. Fortunately, he closed his eyes and tried his best.
"Bounce" out, the muscle strength he had accumulated in his legs was released in an instant, which caused his body to produce a powerful forward force, and he was instantly separated from the necromorph's alien limb. Limitation, even though this kind of separation cost Du Jin a lot of money. He could clearly feel his flesh and blood being scraped away from his back by the alien limbs of the corpse. This was definitely not a good experience, but the price was at least Let Du Jin get rid of the pulling and tearing of the corpse.
In the next one or two seconds, Du Jin only felt that his mind was completely empty, or that it was instantly extracted by some kind of power. He didn't know what his purpose was, and he couldn't remember what he did. Reason, even looking back at the lantern
The "power" is gone, because his memory has become a blank piece of paper. He just wants to sleep peacefully, but strangely, there is a small trace of black in his mind, and his blank consciousness is so Obviously, instinctively, he tried his best to trace that trace, even though Du Jin didn't know what it meant.
at this time
In "reality", or in Xingying's conscious space, Du Jin's eyes are covered with black luster. From the appearance, it is impossible to see the boundary between the whites of the eyes and the pupils. This is in stark contrast to his pale face. In contrast, the corpse transformation on Du Jin only stagnated for a moment. It did not dare to move forward for a while, as if it was extremely longing for the red blood-stained statue in front of it, but also extremely afraid, until Du Jin's left chest and the red blood-stained statue The surface came into contact, and the bright red blood immediately adhered to the surface where the blood mark was not smooth but slightly rough.
But after Du Jin's blood adhered to the surface of the blood print, it was as if there was some kind of chemical reaction. The dots of blood turned into black ink dots, and began to spread around at a not too slow speed. With this spread, The runes on the surface of the red blood seal no longer flashed one by one in this order, but began to flash randomly and irregularly. Even the deer that were still patting each other to drink water by the river just now were suddenly struck by the river. The crocodiles that jumped out were scared and fled away. Although this metaphor is not appropriate for the blood mark, it can very vividly describe the changes in the external characteristics of this statue.
"Horrrr!!!" The corpse mutant then let out a hoarse cry. Although this sound is too different for humans, you can still hear what it wants from it. It was an emotion of rejection, but this rejection seemed to be of no use. Its body hit Du Jin in a twisted posture, as if there was something inside the corpse pulling its body to move in one direction. This is probably
A true portrayal of "Brain: You should be like this, Hands and feet: I don't, just playing". But when a foreign limb was about to pierce Du Jin's neck with a bone blade, the foreign limb suddenly exploded into a ball of blood mist. Without any warning, it instantly changed from an object to a gas, but the corpse's body remained the same. Before it moves forward even a little bit, part of its body, or even a whole piece, will immediately turn into blood mist and stay in the air. It can be seen that it has an influence on Du Jin, who is very close in front of him but just out of reach. Very strong emotions, but helplessly, this emotion does not make it
"Completely" preserved. This blood mist stayed on the side facing the red blood seal, and was immediately attracted by some power of the blood seal. To be precise, it should be absorbed, but it seemed to be too late at this time. The blood mist was covered by the red blood seal and reached those who were constantly The blackness spreading on oneself
On the "wave", but it is not as black as this
The "wave" showed no slight sluggishness or retreat, and the bright blood mist was swallowed up almost instantly, turning into the wave of the wave.
The "accomplice" further accelerated the attack on the red part. The red blood seal seems to have been affected by this scene
It was "shocked". In its consciousness, it seemed that it had never thought that it would swallow and infect humans wantonly, and one day it would be devoured and lose everything. Its surface emitted an increasingly intense red light, a dazzling red light. As if Du Jin was being wrapped inside and burned, Du Jin's hair and eyebrows were disappearing at a speed visible to the naked eye.
His clothes also began to turn into black dust and began to fall to the ground under the action of gravity. The human body can feel the temperature changes of the outside world because there are temperature receptors in the human skin layer. When they are stimulated by cold and heat, they will produce impulses. Sends a pulse signal of about 50mV to the brain.
The strength of the signal is determined by the frequency of the pulse. If a microelectrode is inserted into the axon of a neuron or into a single nerve fiber, these pulses can be recorded directly and their frequency can be observed to change in response to changes in temperature stimulation.
But at this time, he looked like his entire body was wrapped in a ball of crimson flames. However, he was completely immersed in chaos and did not seem to show a normal human reaction to high temperatures. Instead, he maintained the same posture unusually calmly. And his movements were like being roasted by high temperature. Du Jin was just like the crowd eating melon on the side.
And the red blood seal is looking forward to
The scene of "holding the emperor hostage to order the princes" has not yet come, black
The "wave" did not stagnate at all, but began to cover the rest of the area at an increasingly faster speed. There was no hesitation or pause, just enjoying the dripping pleasure. This blood seal was afraid, even if it itself It is synonymous with fear and death, but in the face of the black wave surging out of Du Jin's body, no amount of its efforts can bring back the slightest chance of survival.
I don’t know if it was because of the blood mark that I had the idea of detaching, but many cracks suddenly appeared on the walls of the room, and then the whole room shook, as if an earthquake suddenly came, large and small concrete blocks, lamp fragments, The fragments of decoration fell from the ceiling. Xingying immediately turned her back to the corner to protect her child under her back. She wanted to use her thin body to protect her child who might have died long ago, but where they were The place was relatively lucky, except for some gravel, there weren't many fatal things hitting it.
In contrast, Du Jin was much unlucky. A large piece of material fell on his shoulder, which caused his body to sink suddenly. However, Du Jin had already relied on instinct to cling to the red blood mark. , but judging from the appearance, his shoulder has been severely damaged. This kind of instant death injury is difficult to see even on the battlefield.
Perhaps it was because of Du Jin's persistence, or perhaps because it was too late for the red blood seal to escape and disconnect. When the statue became increasingly dimmer and almost disappeared, the black wave finally occupied the red blood seal. The last sharp corner at the top of the double helix completed what Du Jin expected.
"Swallow", and then the time in the consciousness space seemed to pause for an instant. A concrete block with a diameter of two meters hung above Du Jin's head. It is no exaggeration to say that if this thing hits Du Jin, I am afraid that Du Jin will soon turn into a puddle of meat.
But it did not fall at this time. Everything seemed to have stopped, including Xingying's doubts and joy at this time.
A second before the "pause", she felt a movement of the child in her arms. Xiaoyou in her arms opened his starry eyes that looked very sleepy, but glowed with a different kind of vitality, full of doubts.
The next second, these stationary things began to move, but in the opposite direction. The fragments of gravel that fell to the ground floated up from the ground and flew upward again.
