【Chapter 288】After knowing the reason that hindered him from getting the weapon module on the hovercar at this time, Du Jin first considered the value of the time spent on it, compared to the energy weapons and Gauss rifles around him at this time, where is the advantage of this rapid-fire module, in this world, the development of firearms will not have much development before the revolutionary changes in ammunition technology or energy supply methods.

Now the only direction is modularization, which has basically been explored. The next possible direction is the intelligence of accessories, such as a sight that uses sensors and Al comprehensive analysis to automatically calculate targets, but the practical application is very limited.

Therefore, for the derivative direction of future weapons, it is also ammunition guidance, programming, and simple operation, which minimizes the human factor in the process of use, and most of the operations are completed by the computer system.

The anti-tank missile, which is now launched and left alone, is a representative, and the future trend should be to continue to miniaturize and reduce costs to achieve the role of replacing bazookas.

Therefore, in terms of accuracy, this rapid-fire weapon module may not be able to compare with the tracking ammunition accuracy of the Gauss rifle, and it is slightly inferior to the energy weapon in terms of penetration, after all, the strength and penetration of the radiation beam or laser can be improved indefinitely according to the material of the convergence device, and it is not impossible to develop to the Star Destroyer Cannon in the end, but Du Jin's most important point for this weapon is the unparalleled suppression ability and small logistical pressure, and the word rapid-fire represents a vast ammunition supply as soon as it appears.

Not to mention the kind of rapid-fire alert machine gun with a rate of fire starting at tens of thousands of rounds per minute, the machine gun used in the modern world emphasizes assault firepower, and its rate of fire is generally recommended to be higher than that of heavy machine guns and general-purpose machine guns.

If intermediate-power rounds are used, the ideal theoretical rate of fire is mostly around 800 rounds per minute. It turned out that if the rate of fire was higher, it would be detrimental to the practical use of infantry machine guns.

As for the conventional use of the general machine gun, it should take into account the two forms of light and heavy, the rate of fire is too high is not conducive to the common strafing of heavy machine guns, scattered fire requirements, so the theoretical rate of fire is generally a compromise in 600-700 rounds per minute, as for the machine gun using the principle of conductive gas, the gas regulator will generally be designed, the rate of fire can be adjusted in a small range, and the heavy machine gun is another extreme, it does not focus on the rate of fire, but the damage gain of large-caliber bullets also partially makes up for the problem caused by the low rate of fire, after all, its ammunition specifications are much larger.

According to the information that Du Jin got from Xiao Ai, in addition to the automatic aiming system and stabilization system on the external load, the efficiency brought by electromagnetic acceleration can increase the rate of fire of the machine gun exponentially, which is why the machine tower on the electronic sentry card will swallow up the first half of the hovering car like a swarm, that is, because the jet effect brought by the extremely high rate of fire can dissolve the enemy's armor and everything under the armor on the physical level as efficiently as a cutting machine, of course, Not being able to break the defense is another story............ At this time, Du Jin had no intention of fighting with the Unity Sect and the soldiers who might be assimilated in marksmanship and guerrilla tactics, the former was definitely a gambling duel that did not exist, and the latter was completely killing under the powerful detection ability of the Blood Seal World, so the suppressive power and deterrence were what Du Jin valued most, in a storm

In the "streamer", it takes a lot of perseverance and excellent skills to shoot, Du Jin does not have it, but it does not mean that the enemy has, and the purpose of this electromagnetic rapid-fire machine gun itself is to cover, after all, the special car is specially used to transport and protect special personnel, and it is necessary to take into account safety, aesthetics and practicality, the purpose is to prevent the special car from falling into an isolated and helpless situation that can only seek more blessings and let it be slaughtered.

Therefore, the bomb feeding system of the rapid-fire module is very simple, that is, by dividing the special metal into extremely fine debris, and then through particle solidification and electromagnetic acceleration, it is shot at an astonishing speed, by shortening the size and penetration of the single caliber of the ammunition, as well as the firing range to achieve long-term continuity, wide-angle firepower output, and even through this diffuse barrage to block possible non-laser weapons, so as to achieve the effect of attacking and defending, when Du Jin heard such an introduction, He didn't care about the technical content of this seemingly simple shooting and ammunition supply

"Continuous"

"Wide Angle"

The words "firepower coverage" and other words made Du Jin unable to find reasons and ideas to solve it.

"Master, as long as you can help Xiao Ai unlock the mechanical lock, the software and block part of Xiao Ai will be completely sure☆" Hearing this, Du Jin had a certain degree of confidence in his heart, with his current physical strengthening, although it is not as good as a heavy exoskeleton or a medium-sized exoskeleton that specializes in the handling and transportation of items, his actual strength is almost the same as most light exoskeletons and conventional medium-sized exoskeletons, so Du Jin can completely close the protection system with the assistance of Xiao Ai. Starting from the weak point in the physical blockade device obtained by Xiao Ai's scanning, the outer protection of the entire module is removed to obtain the weapon in it.

Others look at Du Jin's sturdy physique, at most he is a young man who often exercises and spirit, and he would not have thought that his strength is almost the same as the power given by the exoskeleton armor, it can only be said that the limit of flesh and blood is really shocking, of course, this is not just the fault of those exoskeleton designers, after all, from a combat point of view, the large humanoid mecha is not necessary, the form is towering, the area of the bullet is large, it is detected early and destroyed early, it is not as fast as a tank when lying down, it is not as good as standing to see far as Wuzhi, the joints are fragile, and it is easy to fall, Most of the weight is dead weight used to move, which is difficult and expensive to develop.

And in the blue star environment, the humanoid mecha is almost the same as an exoskeleton for individual soldiers, if it is an alien high-gravity environment, a larger cockpit may need to be filled with protective liquids or something, and the mecha has to be used, even so, I personally think that the arachnid design should be used.

Because the humanoid movement performance is really not good. We form an upright form to free our hands, and we only have four limbs, so we can only walk on two legs.

In terms of space utilization, armor efficiency and bombed area, the efficiency of the humanoid is indeed not high. From a design point of view, the boxy shape has the best space design convenience.

And the surface area is smaller with the same volume. The benefits are high space utilization, light armor weight, and a small shell area.

The human body or other organisms have a large surface area, so the corresponding bomb area is also larger.

The area where armor needs to be laid is larger. And the humanoid is still upright. This means that it is the tallest on the battlefield with the same volume.

So the probability of being hit is also greater. And this problem with the human body is the same in many animals.

And the maneuvering principle of bipedal walking and multi-legged mobility of arthropods is far less efficient than that of wheels.

In terms of mobility, it is also completely defeated by the wheels. Therefore, these light and medium-sized protective exoskeletons rely on human body shape to increase the pulling force of muscles, in essence, this is still a kind of external reinforcement of human beings to themselves, and Du Jin's strength through the genetic enhancement of blood marks is not fundamentally different, not to say that there is any change, it can only be said that Du Jin's technology is higher, and the body adaptability is stronger

The "small body" is not enough. After thinking about what he was going to do next, Du Jin didn't delay anything, and while preparing to leave the hovercar through the biometric verification on the door on the side, he asked the main driver: "Is the weapon module on top of the hovercar?" ”

"Uh......... Yes, the specific location is ..........." The main driver hurriedly replied, thinking that Du Jin wanted to retreat in spite of the difficulties, but the next scene made him puzzled, only to see that Du Jin did not wait for the main driver to finish speaking, he opened the car door and walked out, Zhang Jin on the side hurriedly asked the accompanying security personnel to also go out to cover, if Du Jin died not long after he went out, then all the efforts and compromises made by Zhang Jin would be completely ineffective, so there is no doubt about the necessary cover and guards.

After Du Jin left the suspension car, he breathed unusually sober air for a long time, although the time he sat on the suspension car was actually about half an hour, but in Du Jin's subjective opinion, it seemed that he had experienced several days of depression, which was not so sudden, after all, in terms of the torture that Du Jin experienced, it was indeed very much on the subjective level

"Delayed" the passage of time, not to mention that no matter how good the air circulation and purification measures in the suspension car are, there is still a big gap between it and the real natural environment

The "Star Ring" is in no way inferior to the forest on the blue star of the present world. But Du Jin only took a few deep breaths, and then neatly climbed onto the top of the hovercar, his hands touched the cold feeling brought by the unknown material, Du Jin instinctively shivered, Xiao Ai guided Du Jin to quickly find the place where the rapid-fire module was hidden in front of Du Jin's eyes, or in the navigation constructed according to Du Jin's personal senses, the reason why it is called hidden is because if it wasn't for Xiao Ai marking a range box, Du Jin would not have found it at all, This gapless top area hides a weapon mod that can be raised and lowered.

At the limit of the achievable accuracy of the parts in the world, a similar effect can also be achieved, but with the increase in the volume and edge length of the parts, this gap cannot be completely integrated, it will inevitably have certain traces of fit, not to mention that Du Jin's visual nerves have been strengthened, if you look closely at a thing, you can almost use yourself as a microscope of medium magnification, when Du Jin thinks about the actual gap between the current world and the blood-printed world in terms of the accuracy of the parts, Xiao Ai has initially unlocked the blockade system.

Under Du Jin's gaze, the starting top cover of the module was slowly raised, but the lifting range was not large, at most less than three centimeters of distance, it is obvious that although the control system level was cracked by Xiao Ai, but the mechanical restriction Xiao Ai is still powerless, this is a double prevention mechanism, the dual prevention system is divided into risk classification control and hidden danger investigation and management, in order to prevent any party in the mechanical and control system from being cracked by the enemy, the remaining part of the restriction means can still take effect, in the risk classification control part, The focus is naturally on the classification, which is not only to classify the risk, but also to classify the responsibility, and when encountering the corresponding situation, according to the corresponding risk classification method, the risk is divided into

The risk levels of "red, orange, yellow, and blue" correspond to each other

"Significant Risk, Relatively High Risk, Average Risk, Low Risk". The central control system of the front part of the hovercar was destroyed, which essentially triggered the restriction conditions of the red level, and the weapon module that could not get the attack command could not take the initiative to eject and attack, because it would cause friendly soldiers to be accidentally injured or the weapon module would be the first to be terminated, and the last barrier and protection would be lost, so when the two core structures of the cab and the cockpit where Du Jin and some people were located were attacked and damaged, the weapon module would automatically pop up and catch the enemy off guard. But at this time, Du Jin's purpose was to dismantle the electromagnetic machine gun, and naturally he couldn't let it activate the attack state, otherwise he would go up and forcibly dismantle it, and it would be funny if it was identified as a hostile target and made into a sieve.

After the hierarchical control, it is the hidden danger investigation and management, the significance of which is to investigate the hidden dangers according to the relevant standards, and reduce the possibility of accidents and even curb the occurrence of accidents, that is, in the process of hidden danger investigation, it is necessary to know which risk points exist in the corresponding safety hazards, such as what kind of circumstances will cause accidents, and according to the conventional production environment and principles, the existence of potential safety hazards usually stems from four factors, namely: unsafe behavior of people, unsafe state of things, The cause of the environment, the lack of management, that is, the commonly referred to as people, things, environment, and management.

The corresponding measures of the weapon module on the hovering car are to establish a double set of prevention mechanisms to prevent the appearance of internal ghosts in the hovering car, unlock defensive weapons in advance through the control system, so that the enemy can get a chance to be defeated, or carry out a surprise attack on friendly units next to the hovering car, so that the weapon that should be fire support becomes a sharp blade for the internal ghost to know that he is a threat to himself, and the mechanical part is to ensure that the self-defense weapon is attacked and damaged before the two core structures of the cockpit where Du Jin and some people are located. It will not be used rashly, causing unpredictable negative situations to occur.

Corresponding to this dual prevention mechanism, it is the most common traditional control measures in the world, that is, the back-end control, that is, the hidden danger is only managed after it occurs, but often the accident has only broken out in a short period of time, and the later control can only reduce the loss but not the occurrence of the accident.

The key to the dual prevention system is to move the pass forward and defense in depth, which is to eliminate the outbreak of accidents before they occur, and strengthen them with control measures

The control of the four items of "people, things, environment, and management" reduces the frequency of accidents, thereby reducing the harm of accidents, namely

"Pass Forward". Under normal logic, the risk is attached to the risk point, and if there is no problem in the four links of human activities, the state of facilities and equipment, environmental factors and the influence of management, the risk is only a risk, not a hidden danger, and will not become an accident; However, if there is a problem somewhere in these four links, the risk attached to the risk point will be transformed into a hidden danger, and if there is no corresponding control measures, then this hidden danger will then change into an accident.

The key to prevention is to curb or even reverse this process, although the prevention mechanism of the hovercar weapon module has far more harm than good to Du Jin at this time, but he also knows in his heart that this design is undoubtedly the safest.

But fortunately, the prevention mechanism is still within the scope of Du Jin's plan, and he knows very well that he does not have the talent of engineers and mechanical repair experts, so he did not plan to open the blockade by conventional methods from the beginning, but was prepared to use a very simple and crude but effective way: strength, of course, strength also requires skill, only know that the raw pull is called recklessness and brute force, in addition to strength, strength also needs to measure the situation and make corresponding measures, in order to be regarded as a real strong.

The mechanical limitation part of the rapid-fire module is designed for the standard of heavy exoskeletons, and it is very difficult for Du Jin to forcibly destroy the entire blockade device with his own strength, but there is a trick in Xia Guo's tactics called breaking the surface with points, dragging knives, returning to the horse gun, and making a move, all of which are sold flaws to win, all of which are to break the surface, break the deadlock, break the calm, and open the situation, and deal with the intricateness, you can pile up firewood and light the fire, fan the wind and ignite the fire, take advantage of the fire to rob, take advantage of the weakness, take advantage of the chaos to change, the sound of the east and the west, the wind is loud, and the situation is embattled.

This is vividly shown in the human body, a person with a strong physique, there are also dead points in his body, such as the carotid sinus body, its position is about the upper edge of the thyroid cartilage in the neck on both sides of the level, in layman's terms, the position is below the earlobe, above the Adam's apple, on both sides of the neck, the reason for the fragility here is that there is a special sensory terminal plate in the arterial wall here - baroreceptors, which are surrounded by rich plexuses.

The carotid sinus senses the change in the pressure in the lumen of the artery and reflexively regulates blood circulation in the brain, and this reflex is called

Stimulation of the carotid sinus can affect arterial blood pressure, heart rate, myocardial work, cardiac output, arterial resistance, and venous volume, resulting in a slowing of heart rate and a drop in blood pressure.

Thus, when the carotid sinuses are hyperactive, they can cause episodes of vertigo, fainting, or convulsions. Or the temple, the thickness of the skull that protects the temple is only about a millimeter, and it hardly plays any protective role, and by extension, no matter how complete and solid the surface is, there will inevitably be a relatively fragile point, and you only need to start from this point to find a much simpler, much easier way than breaking the whole surface.

"Xiao Ai, it's up to you." Du Jin whispered please, and put his wrist on the gap where the rapid-fire module bounced, a faintly visible blue light flashed, and after a while, a three-dimensional mechanical blockade structure diagram appeared in front of his eyes, the whole structure is not much complicated and blocked, but in fact, the simpler the structure, the less places can start, the road to simplicity is not an empty word, but fortunately, Du Jin does not need to find out the missing points in the design, Xiao Ai can pass structural mechanics, material density, The link method and design principle are comprehensively evaluated in many aspects to achieve the most efficient planning and deployment in the shortest time.

"Master, Xiao Ai has found four weak points, which have been marked in front of the master, I believe that the master must be fine, come on" Soon Xiao Ai presented the results in front of Du Jin's eyes, four light red imprints appeared in the digital picture in front of Du Jin's eyes, and Xiao Ai on the side also gave four weak points very professionally, respectively, from what angle to start to realize the principle of paralyzing the physical blockade structure, after responding to Xiao Ai's cheering in his heart, Du Jin immediately began to try, he did not stumble on a weak point, but ready to try all four of them on one side, he saw his hands slowly stretch out of the gap where the top cover of the module popped up, stabilized his shoulders and body, took a deep breath and suddenly forced, Du Jin's luck was obviously blessed, as his instantaneous explosive power continued, two seconds later, starting from the other side of the top cover, the mechanical device that stuck the top cover seemed to suddenly lose its effect, and the gap began to expand rapidly.

Immediately after that, several pieces of fine parts burst out from the expanding gaps, scratching Du Jin's hands and side face, one of which even penetrated the flesh and blood at Du Jin's knuckles due to the greater strength of the angle, and the blood quickly flowed out of the half-torn wound, but only two or three seconds later, a crimson blood scab appeared at the wound, and the blood began to slowly condense, Du Jin looked at his strong self-healing ability, and what appeared in his heart for a while was not joy, but helplessness and worry about the future, his body has been further strengthened, The self-healing ability visible to the naked eye is the best embodiment, but the transformation of flesh and blood makes Du Jin instinctively feel a little chilly, he is afraid that this is the point of no return for him to become some kind of body or flesh monster step by step.

"Hey, okay, wait until this time is done, and then talk about ................. when you return to the present world" Du Jin tried to suppress the worries in his heart, concentrating on the things under the top cover that had been forcibly opened by himself, only to see a gun-shaped object with an extremely heavy sense of security appear in his field of vision, and the flickering ghost light in the acceleration ring at the rear end seemed to slowly soothe Du Jin's originally slightly frightened heart,

"The fear of all the unknown comes from the lack of firepower", this joking sentence appeared in Du Jin's heart, and at this time he just wanted to echo a sentence: "That's right!" It just so happened that at this time, several heavily armed escorts found Du Jin half-kneeling on the top of the hovering car, but looking at the alloy top cover that Du Jin was holding in his hand that was obviously lifted from a certain part, they were speechless for a while, and they didn't know what to say.
