【Chapter 189】Thanks to his intuition for decades of special work, he told Qi Guangyu that that thing belonged to some kind of surveillance equipment, and Qi Guangyu was not actually his own face now, but was wearing a special fit-fitting simulation mask, which is often said

"Human skin mask", but this is not the type of mask that people usually use, due to the influence of the material and the rich muscles on the surface of the human face, the reality wants to achieve

The effect of "changing the head" is almost impossible, high-level camouflage, in fact, it is a mask, when you disguise yourself as someone, if we look at a man and want to change his appearance, start from the top is the hair, what kind of hair does he have, does he have a beard, we may have to give you some stickers, we will also do prostheses, you can change your frontal bone, add a forehead, you can make a fake nose or, braces, with some suitable braces can change your face shape, called a tooth augmenter can change the fullness of the gums, This is used to change the shape of your face, and the last one is an artificial palate, which is attached to the upper part of the mouth, which can change your accent.

And Qi Guangyu used the latter, and the simulated mask was only to change some of the facial features, but even so, with Qi Guangyu's technique and proficiency, even if someone approached to observe him within one meter, he couldn't judge that this was a disguise, which was also the key reason why he escaped under the enemy's nose in many previous missions, but now that someone was eyeing him, Qi Guangyu immediately realized that the party that was monitoring him was to accurately know his identity and disguised appearance. Keeping track of yourself from the moment you leave the office is definitely not something that the average person or organization can do.

I think of my own morning assistant

"Attentive", Qi Guangyu seemed to understand something: "I didn't expect that I had been on guard for decades, and finally I was toyed with by my most trusted subordinate, it seems that I am indeed old....................... "It is also the case, Qi Guangyu became more and more interested in the young man in front of him, not to mention the obligation to save an old man who had never met in his life, how rare it is in this era, aside from this, the young man can pull Qi Guangyu back from the brink of death, Based on this alone, Qi Guangyu was very surprised, he was very aware of his condition, whether it was the organization or Qi Guangyu himself over the years, he had been treated by many famous doctors in the heart field, and the conclusion of the examination was either euphemistic or direct, but it was very clear that unless a high-risk operation was performed, he could only enjoy the last beauty in the remaining time.

But now he obviously feels that his body is improving, Qi Guangyu's angina pectoris was commonplace before, if it weren't for the breath in his heart and his belief in the country, let alone continue to work, I am afraid that he will be tortured and even have no hope and courage to live, which is also the main reason why Qi Guangyu did not agree to the treatment and wanted to finish his future affairs and responsibilities in the last time as much as possible, he was really tired, whether it was the review and analysis of all kinds of special intelligence information, Or the command of the intelligence operation, under the addition of illness, he was physically and mentally exhausted.

But because of this, Qi Guangyu obviously felt that his body, especially his heart, was like

Like "reborn", the labor pain and depression in his chest that had plagued him for I don't know how many years did not appear, but was replaced by a kind of peace and stability, which for Qi Guangyu was like a person who had been imprisoned in a dark cage for many years, and was released in an instant to see the bright sunshine again, although some

The discomfort caused by "dazzling eyes", but this change produced an incomparable joy in his heart.

"Thank you, lad!" Qi Guangyu controlled his emotions as much as possible, and said to Du Jin in a calm and grateful tone, Du Jin shook his head lightly, according to Xiao Ai's feedback in his mind, the current recovery progress of the diseased area has reached more than 80%, which makes Du Jin's worries gradually disappear, but then there is a trace of nervousness and helplessness, after all, Qi Guangyu has thanked him just now, which means that the other party has understood the meaning of Du Jin's treatment now, Du Jin has no doubts, After all, the body belongs to other people, not to mention the problem of the heart, even if a thorn is pierced in and then pulled out, he can feel it.

What really worries Du Jin is how to explain himself

The existence of "treatment", judging from Xiao Ai's investigation of Qi Guangyu's identity, the Special Operations Section is a special organization that carries out internal anti-infiltration and invasion by hostile forces, and its authority is very high, and the first and second sections set up in it actually do not have any real power, but only auxiliary operation departments, and the real ones with real power and personnel and equipment management authority are the three sections headed by Qi Guangyu, Du Jin does not believe that officials of this level will not be able to enjoy the top medical treatment in Xia Kingdom.

Since Qi Guangyu can get sick on the street, and judging from the results of Xiao Ai's scan, it is obvious that the medical treatment in the world cannot cure or the risk of cure is extremely high, so Du Jin is cured like this, and when the other party goes to check it again, and then asks him about his own treatment method, Du Jin can't explain it, after all, whether it is the VII-7 polymer or Xiao Ai itself, it is not information that he can explain and reveal.

"In the past, I only saw that this old man's position helped me to expand my network quickly, coupled with his sacrifice to the country, so I was treated, but now I think that the risk is not ordinary................... Forget it, if you come, you will be safe, I hope this old gentleman is the one who is easier to communicate......................" At this moment, Du Jin suddenly felt a chill behind him, which was similar to the feeling he felt at the gate of the military academy last time, but this time it brought him a greater sense of crisis, and the instinct of his body told Du Jin that he should dodge, otherwise there may be extremely serious consequences.

"There's a hole in this perception, huh? Don't tell me which direction to dodge, if you happen to be hit by some attack, isn't that relative to flashing graves? ......................" This kind of complaining about himself only appeared in Du Jin's heart for a moment, but the complaining was a complaint, he didn't think that his senses were joking on him, and grabbed Qi Guangyu's shoulder in front of him and flashed to the right, it was not his intuition to choose this side, but this side was closer to the edge of the bench, and a larger evasion space could be formed towards this side, and it was also convenient to quickly take Qi Guangyu to avoid the chill on his body through the street corner

Gaze. Du Jin's pull caught Qi Guangyu a little off guard, but before he could say anything, at the moment when Du Jin threw himself on the ground, Qi Guangyu heard a penetrating sound on the wooden bench, and experience told him that this was the sound that a certain high-speed object could only make by penetrating the wooden structure with kinetic energy, and this kind of high-speed object Qi Guangyu couldn't be clearer, that is, a bullet, and he realized where Du Jin's reaction came from at this time.

And Du Jin, whose senses were strengthened, saw more than Qi Guangyu, he even saw the flying debris generated by the bullet passing through his side and shooting into the bench, this time Du Jin was full of gratitude to his senses, and while the center of gravity of his body had not completely disappeared, he staggered on his hind legs and barely stood firm, but Du Jin did not hesitate, and immediately supported Qi Guangyu beside him and ran towards the street corner not far from them, although his series of actions seemed a little funny to passers-by, and even a little neurotic, But Du Jin didn't have time to care about that.

Fortunately, the gunman who tried to shoot Du Jin or Qi Guangyu did not make a second shot, and because the other party was using a gun equipped with a silencer device, the so-called gunfire was that after pulling the trigger, the firing pin inside the gun hit the base of the bullet, and then ignited the gunpowder inside the bullet to explode instantly.

The cartridge case is then ejected, and the bullet is ejected through the spiral barrel rotation. Therefore, the main sound produced by the gun when it is working is first from the sound of the movement of parts and components after the trigger is pulled, followed by the muzzle impact sound caused by the explosion of gunpowder, and finally the sonic boom sound generated by the bullet breaking through the sound barrier when it flies out.

However, the crucial point is that there is no way to intervene in the first part of the sound after the trigger is pulled, and the sonic boom of the bullet flying out.

Therefore, it is only necessary to make a fuss about the muzzle impact. The reason why this sound is loud is because after the gunpowder in the bullet is ignited, it will explode instantly in the small space of the gun body and produce tens of thousands of kilopascals of high-temperature compressed gas.

This sound is about 130-150 decibels, similar to the sound of jet planes, and the silencer is going for this sound.

The structure of this silencer is usually a tube with a hollow middle part and a series of air chambers formed by layers of resistors around it.

Its function is to give a buffer zone to the expanded gas when the bullet is ejected, so as to slow down the speed of gas outflow as much as possible, and then achieve the effect of silencing.

Generally, the gunfire after the silencer blessing will be about 100 decibels, which is about as loud as the starting sound of the diesel engine, and it is precisely because of this that the silencer has a major role when it is used: that is, in reality, due to the reduction of the amount of gunpowder of subsonic bullets and the aggravation of the warhead, its power and accuracy are relatively small, so it is rarely used.

And the silencer though can not do it, so that conventional bullets and subsonic bullets have the same effect. But it can make the sound of a gunfire with a silencer sound not like a gunshot.

And at this time, it is more like a tracer. It was precisely because the gunshots were disguised as other sounds that they did not cause panic in the flow of people, for Du Jin's

"Dodging" provides a lot of convenience, otherwise the chaotic flow of people is definitely the biggest trouble when dodging pursuit, especially when being condescended by the enemy.

In fact, the shooter who was hiding in a car did not choose to continue to replenish the gun after a miss, but immediately put away the gun and drove away quickly, it is impossible for a person of Qi Guangyu's level to be secretly protected by someone, even if according to the intelligence Qi Guangyu was alone today to disguise himself in order to go to the martyr's cemetery to visit his comrades, but the intelligence is not necessarily absolutely accurate, this is an unspoken rule in the secret operation, this gunman is very cautious, He quickly removed some attachments from his face during the driving process, making his face change from a middle-aged uncle with a scruffy beard to a very ordinary face, I have to say, this face is definitely an intelligence officer

"Good helper", blending into the crowd can be completely hidden. The man drove the car through an intersection, and then stopped in an alley, he first put a gun with a special shape in a bag that was originally used to carry a certain musical instrument, and then threw a square-shaped box in the car, then he got out of the car and saw that there were no pedestrians passing around, so he put on a wide-brimmed hat to cover his eyes, and then walked quickly through the alley with a relaxed smile on the corner of his mouth, and when he saw the dark black car at the end of the alley, his obviously tense body relaxed, as if he saw the eyes of a smooth departure.

As he walked out of the alley, one hand was placed on his shoulder, and the other was holding something hard against his waist, which made the man's otherwise relaxed body tighten, and then a voice with a smile came from his ear: "It's hard work, isn't it?" Walk! Let's go somewhere and drink tea, don't be nervous. Hearing this, the man did not hesitate to raise his hand to remove the power pressing on him, and left while he was in chaos, but before he could act, he suddenly felt a tingling pain in the back of his neck, and then ............... His consciousness fell into darkness, and the root cause of fainting caused by attacking the back of the neck was insufficient blood supply to the brain, of course, he wanted to make the brain insufficient, compared to the back of the neck, it was faster to attack the side of the neck closest to the carotid artery, medically, this kind of syncope triggered by external force is called carotid sinus syncope, of course, the latter is very risky, and it is easily fatal.

Looking at the attacking gunman who was paralyzed on the ground, a man on the side immediately held down the headset and shouted: "The first team has ended, the second team immediately followed up to make sure that there were no other helpers absconding, and the third team went to find the section chief." ”

"Yes!" ...................... Du Jin leaned against the corner window, breathing rapidly and waited for a moment, his senses did not remind him that there was any crisis, but he did not expect that he had the same sense as a superhero, in order to avoid himself being squatted by others, he immediately said to Xiao Ai in his mind: "Xiao Ai, connect the nearby monitoring system, help me check which direction it was just now, who attacked it." "'Master, take a rest, Xiao Ai is going to check it out a moment later, a picture that was spliced together appeared in Du Jin's mind, he saw a very ordinary black car parked on the side of the road, in the southeast angle where Du Jin is, the black window slowly rolled down a small slit, and then a faint point of light flashed, and Du Jin on the other end of the picture was blankly avoided, and the attacker in the car saw that he didn't hit, so he immediately rolled up the window and drove away, and then Du Jin saw a face that looked very vicissitudes in the traffic monitoring probe arranged at the intersection, but Du Jin's intuition told him that this face was a little discordant。

"Master, Xiao Ai searched the official database and did not find a face similar to it in Wanglong City, but according to Xiao Ai's simulated face shape after processing, the other party should be one of the following people." Then three photos appeared in Du Jin's mind, in terms of appearance, it was completely different from what Du Jin saw in the traffic monitoring probe just now, but Du Jin looked at the three photos and was also at a loss, and he had no contact with similar people in his impression.

"Could it be those agents or spies from country M again? No matter how they chase me, alas! Du Jin complained helplessly in his heart, and Qi Guangyu on the side patted Du Jin's shoulder at this time, and after Du Jin's eyes moved to him, Qi Guangyu said in a very kind tone: "Thank you again, little brother, you have saved the old man more than once." Hearing this, Du Jin didn't know how to answer for a while, and hesitated for a few seconds before saying, "Ahem............. Old gentleman, you don't have to be so polite, I just did what I had to do, as for the ones I ..................... just now" Qi Guangyu seemed to understand something in Du Jin's hesitation, he smiled and waved his hand, and then said again: "I understand, I understand, everyone has some secrets, since you saved me, I naturally won't force any answers." At this time, a black SUV stopped on the side of the road, but no one in the car got down, it seemed that he noticed that Qi Guangyu was communicating with someone, and did not take the initiative to disturb, Xiao Ai immediately said in Du Jin's mind: "Master, this is the Tiger Roar-2 that is beneficial to the national special operations department, according to its ownership, it has recently been called by the Special Operations Section." Hearing this, Du Jin immediately understood that this was the person who came to pick up Qi Guangyu, but he didn't expect these people to arrive so quickly, Qi Guangyu and him were attacked for less than five minutes just now, I'm afraid this speed has been guarding the side, right?

At this time, Qi Guangyu on the side did not shy away from anything, and took the initiative to say to Du Jin: "It seems that mine."

"Children" came to pick me up, little brother, let's go together, I can also send you where you are going, I hope you don't solve it, this is just a little bit of a wish to repay you for saving me. Du Jingang wanted to refuse, but considering Qi Guangyu's identity, he still suppressed the words that had just come to his lips, and said instead: "Then trouble you, old man!" ”

"Hahaha, no trouble, no trouble." Qi Guangyu smiled and waved his hand, and then let Du Jin walk in front and follow behind Du Jin, which in itself showed an attitude of his, after opening the car door, the two people in the driver and the co-pilot glanced back at Du Jin, but after they saw Qi Guangyu who was following Du Jin nodded, they didn't say anything, and after getting in the car, Du Jin

"Honestly" reported the address of the Xia National Defense Military Academy, Qi Guangyu's eyes narrowed slightly, and then he thought of a name he saw on the file not long ago: Du Jin, when he first saw this file, the task requirement was to investigate its identity information, and less than a day later, the task requirements became protection and concealment.

Especially this one

The task requirement of "hiding" surprised him very much, this task Qi Guangyu has not seen before, but it is more for those who have been discovered by the enemy to forge the identity of their own intelligence personnel, but now for one

"Unknown".

The "newcomers" adopted similar protection measures, which undoubtedly proves that the upper echelons attach importance to and worry about Du Jin.

Thinking of the details in the file, Qi Guangyu looked at Du Jin who was sitting on the side and looking out the window, and couldn't help but think of some details on that document, such as the indescribable recovery speed in the hospital after blocking the gun for Captain Si Qing, and the ace agent who was killed by the M side not long ago

The "lone wolf" was brought to the brink of death, but in the end he miraculously recovered quickly, Qi Guangyu thought of Du Jin's series of actions just now, and he couldn't imagine that he had been fatally injured in a few days.

To put it simply, there are four processes for general injury recovery, the first is the first step; Early changes in the wound: because the wound has tissue necrosis and blood vessel rupture, there will be an inflammatory reaction, blood vessel congestion, inflammatory cell exudation, so it will be red and swollen, and the blood and fibrinogen exuding from the wound will coagulate into a clump to form a crust, thereby protecting the wound.

The second part is that after 2-3 days of wound contraction, the fibroblasts of the muscle layer of the wound skin and subcutaneous tissue proliferate, stretch the edge of the wound to the center, and shrink the wound, this process generally stops in 14 days, and it should be noted that the wound contraction has nothing to do with collagen.

The smooth recovery of medical judgment, that is, granulation tissue proliferation and scar formation begins on the third day, at this time, granulation tissue grows at the bottom and edge of the wound, which is generally caused by fibroblast proliferation, and the granulation tissue is rich in blood vessels, and after maintaining such self-repair for 5-6 days, fibroblasts produce collagen fibers and form scars, so collagen fibers are the main components of scars, and finally, the collagen fibers in the scar will gradually be parallel to the skin surface, and then stop growing and oozing.

In fact, generally after 1 day, the basal cells at the edge of the wound begin to proliferate, and migrate to the center of the wound under the clot to form a single layer of epithelium, covering the surface of granulation tissue, and when these basal cells begin to meet, contact inhibition, it will stop migrating and differentiate into squamous epithelium, so if the granulation tissue is produced too slowly or the foreign body stimulates the generation of too much, it is not conducive to wound healing.

Of course, when it comes to organ recovery, it is very complicated, not just tissue recovery, but Du Jin's specific recovery ability is really a little surprising, but the upper level puts Du Jin's this

The "anomalies" were kept secret, and no similar research was conducted.
