Another world conquest manual

Considering that it takes time to collect information, the rabbits were not in a hurry to let Yang Hengjun send the false images to the mountain col.

Generally speaking, it is normal for a city of this size to take a day or two to figure out the layout.

For example, when Julien first arrived in Chixian City, it took nearly a day to collect information - this was a time-consuming situation when the beast wave was approaching and many businesses and residents in the city did not go out.

For a task like Yang Hengjun's that requires detailed information and is classified into many categories, it is normal for it to take five or six days.

Anyway, according to Yang Hengjun's explanation, the time limit given to him by the Mo family was one big Mo day, which was one hundred and sixty-eight hours.

Therefore, the headquarters planned to let him go to the col after three or four days, which should be the most appropriate time.

While Mr. Rabbit 91 was busy shooting videos.

At the sergeant base located more than 20 kilometers away from Chi County.

Lin Li and Lin Ziming were following a chubby scientific research expert towards a shooting range.

This expert is of medium height, with a waistline slightly smaller than Zeng Gucheng's. His eyebrows are extremely thick, somewhat similar to Tsumugi's strong eyebrows in "The Girl with a Light Sound".

Therefore, he looked smiling and extremely kind.

But in fact, hidden under this smile is a chilling aura that scares countless foreign enemies.

This chilling aura does not come from that chubby body, but from his research results.

That's right, he is Tang Pin, a well-known local weapons expert and one of the absolute authorities on firearms.

He once participated in the design and development of the Type 95 gun family and made great contributions to the rabbit weapons. In recent years, due to the pressure from across the sea, he began to specialize in the study of bullet trajectory.

By the way, this person is responsible for the 59 modifications that everyone talks about every day. The ballistic design of the main gun was made by him.

Tang Pin came to the Great Mo Realm at the same time as Hua Jun, another academician in the camp, but the situation between his team and Hua Jun's Armor Research Group (now the Defense Talisman Research Group) was completely different.

Hua Jun's research team has made continuous achievements after arriving in the Great Mo Realm. Not only did they crack the first-order physical shield and optimize the psychic shield, they also developed an escape launcher based on the first-order escape talisman. Recently, There are also some branch studies that have produced results.

Hua Jun's research group can be said to be one of the groups that has made the most achievements and contributed the most in the camp.

Without the psychic shield and the first-level escape talisman, the capture of the Xiaolianzi Mountain battle would have been many times more difficult, and the casualties would have definitely increased dramatically.

It’s not even certain whether the core layer will start this battle.

Therefore, during this period of time, Hua Jun's reputation in the camp was very high. In the words of the fan circle, he was a top-notch giegie.

But Tang Pin's team is different.

Although they arrived in the Great Mo Realm together with Huajun's team, until today, they had barely made any noise and had been doing scientific research with their heads covered.

Even if it weren't for the fact that the consumable records of each laboratory had not been reviewed and signed every two or three days, Lin Li almost forgot that such a team existed in the camp.

It's not that Lin Li is a snobbery who only values ​​teams with good results, but because the work in the camp is so busy that sometimes he forgets about those little transparency without even realizing it.

But today's situation seemed a little different. Lin Li had a hunch that Tang Pin might have made a new breakthrough in a certain field - something extremely important.

Seeing that he was approaching the shooting range, Lin Li became more and more curious and couldn't help but ask:

"Academician Tang, has your team made a breakthrough in weapons?"

Tang Pin still looked cheerful, but the front teeth that he had been refusing to reveal before were finally opened:

"Yes, we have just developed a new weapon, or a new bullet."

When Lin Li heard this, his expression immediately straightened:

"What bullet?"

Without stopping, Tang Pin reached out and carefully took out a piece of white cloth from his breast pocket.

Then he took a deep breath and slowly opened the white cloth, only to see a silver bullet much larger than an ordinary bullet lying quietly on it:

"That's it. 12.7mm psychic focused armor-piercing projectile."

Seeing that Lin Li didn't seem to fully understand, Lin Ziming on the side added:

"12.7mm, it's a sniper rifle bullet."

When Lin Li heard this, his breath suddenly froze.

Although he is not a weapons expert, and his major does not consider using biological bones to hit people, and it has nothing to do with weapons, but he is very clear about a concept:

The sniper rifle is a targeted killing weapon, and its killing effect on a single target is much greater than that of a submachine gun!

Then Lin Li wanted to ask some questions, but Tang Pin happily shut his mouth.

There is no way, people engaged in weapons research and development are like this, and they are very tight-lipped.

Then the three of them walked hundreds of steps and finally arrived at the shooting range of the military base.

At this time, the shooting range was under strict security, and there was only one gun on the gun storage platform.

This gun is somewhat familiar to everyone. After all, its appearance is so special that you will never forget it after seeing it once:

Model JS-05 sniper rifle, the best sniper in Asia.

The first time Lin Li saw this gun dates back to more than two months ago, when he brought back to Qin Zhendong a report on the benchmarking of Damojie and local weapons.

Among them, the JS-05 sniper rifle is the most penetrating firearm except for artillery shells. It can almost penetrate the external protection of second-level monsters, that is, the early and mid-term practitioners of the Foundation Establishment Realm.

There's nothing you can do if you go higher up, and the rabbits can only rely on various shells to increase the kill limit.

"The reason why firearms have an upper limit is very simple - firstly, its bullet weight is insufficient, and secondly, its muzzle velocity is limited. To put it bluntly, it means insufficient kinetic energy."

At this time, Tang Pin was stroking the gun body of JS05 and explained to Lin Li:

"The weight of the bullet is limited by the volume of the bullet itself, even if it has a steel core, lead lining, and copper armor, the weight will be the same.

The exit speed is provided by gunpowder. At the same time, due to the limitations of the gun chamber, the fastest sniper bullet currently has a muzzle velocity of 800-1000m/s. "

What Tang Pin said is a well-understood concept, that is, E=1/2mv^2.

As for the muzzle velocity mentioned by Tang Pin, it means that the high-temperature and high-pressure gas pushes the projectile in a single-sided closed pipe. After the gunpowder is fully burned for a period of time, the gas speed gradually decreases, while the live projectile speed gradually increases until the two are equal. At this time The projectile reaches maximum velocity and leaves the muzzle.

After introducing the basic concepts, Tang Pin took off the JS05 from the butt of the gun. The twelve kilograms of load made his shoulders sink significantly, making him look like he was holding a watermelon:

"The 12.7mm psychic armor-piercing sniper bullet we improved can accelerate the bullet twice in the air.

At the same time, it can also give the warhead a self-sharpening effect, allowing it to maintain a good penetration shape, thereby achieving adiabatic shear fracture and ultimately armor penetration. "

Seemingly seeing that Lin Li and Lin Ziming had difficulty understanding this passage, Tang Pin continued:

“You two, the self-sharpening effect can literally be understood as the effect of self-sharpening, that is, the bullet’s warhead can continuously deform and peel off, always exposing the solid hard part of the bullet core to continue moving forward.

For normal bullets and even armor-piercing bullets, the impact is a real frontal collision, so the warhead will be compressed after the collision.

If you two still don't understand, go back to the camp and try to poke a thicker sponge with a pencil, and then you will understand it easily by looking at its tip. The pencil has the effect of its own pencil sharpener. "

Lin Li nodded thoughtfully and said:

"I seem to understand a little bit, but Academician Tang, how did you achieve this?"

Tang Pin raised two fingers and explained to him:

“The first point is that we have innovated the material of the bullet and used some kind of strategic grade sharp tungsten alloy.

The melting point of this alloy is relatively low. Under the high temperature of impact, the tungsten alloy will continue to liquefy and peel off at high temperatures. At the same time, it will decompose in layers and planes after being subjected to pressure, but the hardness of the tip is extremely high.

In other words, it will become more and more pointed, and the penetration effect will become higher and higher, until it completely penetrates or loses kinetic energy and stops moving forward.

This behavior is somewhat similar to glaze-poor crystal, but the pollution and radioactivity of that material are too high, so we cannot use it anyway.

As for the second point, we added a very small warhead to the second half of the bullet. "

"Warhead?"

During this period, Lin Li, as the general person in charge of the camp, knew a lot about weapons, especially some basic ammunition concepts, so he immediately asked:

"Is it the part behind the missile body? But isn't the warhead loaded with explosives?"

"That is the warhead of the artillery shell. The powder load is basically in kilograms. The warhead of our armor-piercing bullets is different from them. It is a two-way acceleration array."

As Tang Pin spoke, he took apart the tail of the bullet, revealing a small thing similar to a button battery, and introduced:

"The so-called two-way acceleration formation refers to a strong acceleration formation that applies horizontal thrust to the right, and a weak force formation that applies horizontal downward thrust.

The driving force of the former is more than 7,400 times that of the latter.

The powerful acceleration array is like the secondary ignition of a missile. It gives the bullet a faster speed during flight, giving it greater penetrating power.

As for the weak force push method, it is for the impact in the vertical direction, so that the overall bullet has a more stable trajectory, so that it can accurately hit the target. "

Just as Tang Pin said.

The powerful acceleration array is inspired by the first-order light talisman discovered by Hua Jun before. It can make objects move faster in the forward direction. For example, people can run as fast as Western reporters when using it.

After improvements by Tang Pin and his team, this talisman was optimized into a tiny version of the acceleration formation, which could instantly increase the rate of fire of bullets.

This formation is not difficult to operate. In a sense, micro-engraving is not even a black technology.

What really cost Tang Pin's team a lot of thought was the weak force formation that exerted horizontal downward thrust.

The ballistics of bullets is a very complex thing, involving many principles, and it takes only a few years to get started with the knowledge.

However, there is a basic concept that should be widely spread, that is, the trajectory of a bullet is a parabola.

Of course.

In actual combat, the trajectory of the bullet is not a simple horizontal throwing motion, but an oblique upward parabolic trajectory. It is just used as a metaphor for the convenience of understanding.

Little known.

If the speed of a horizontal parabola in the horizontal direction is greater, the object will eventually fly farther - this can be seen very intuitively just by pushing the coins outward with different strengths at the corner of the table.

Therefore, once the bullet accelerates horizontally, its kinetic energy is indeed great, but it will fly past the target and become a wave of human body stroke art.

To make things more complicated, if the bullet accelerates during flight, its trajectory will be messy like Planck's hair, making it very difficult to locate and describe.

Therefore, Tang Pin’s team spent more than a month conducting ballistic simulations after several studies.

In the end, after paying more than two million in electricity bills and more hair, they finally developed such a miniature weak force formation.

There is an ultra-small technology switch connected between this formation and the powerful acceleration formation. The logic of the two is very simple:

It activates once the bullet's horizontal velocity reaches a certain threshold.

When activated, this weak force formation will provide a downward push, giving the bullet a small but total downward acceleration to fine-tune the trajectory, thereby speeding up the bullet's landing and hitting the target.

If you want to increase the bullet range, you can remove this weak force formation and install another tactical rail for guided shooting.

Then Tang Pin handed Lin Li a form with various detailed data written on it. It was densely packed and made a thick stack:

"Team Lin, according to our optimization, the maximum speed of this 12.7mm psychic armor-piercing sniper bullet is no longer the muzzle velocity, but the instantaneous speed when the bullet flies to 0.113 seconds. This peak can reach 4700m/second. The warhead's The bomb load is 21.2 grams.

Of course, in addition to speed, the armor-piercing kinetic energy of a bullet is also related to mass. Therefore, despite the high speed of this bullet, the current penetrating kinetic energy is also relatively limited.

After all, the speed of other artillery shells or ballistics may not be comparable or even worse by several orders of magnitude, but the ammunition load of their warheads is measured in kilograms.

After deducting the damping coefficient, contact area and collision time, some shells are not as good as them, but some armor-piercing shells are still more powerful than them.

However, this does not mean that the 12.7mm psychic bullet is useless. Its concealment and speed are there, and the success rate of killing a single target within the range is many times higher than that of armor-piercing bullets.

For example, the currently most cost-effective bullet is a bullet with a warhead size of 24.3 grams. Although its peak speed can only reach 4100m/s, its total penetration kinetic energy can reach 16977.3 joules after deducting air resistance. "

Lin Li frowned slightly when he heard this:

"Wait a minute, Academician Tang, the kinetic energy of this bullet is only 1,617,000 joules, right? That's 17 kilojoules?

But I remember that the flame of a second-level monster is more than a thousand kilojoules. Is there such a big difference between the two? Is there a miscalculation? "

Tang Pin shook his head, knowing that Lin Li had fallen into a typical misunderstanding, so he explained with a smile:

"Team Lin, the calculation concept of armor penetration is within the scope of stress issues. In other words, in addition to muzzle velocity, the contact surface and contact time, as well as the difference between kinetic energy and momentum, must also be taken into consideration.

The figure of seventeen kilojoules seems to be hundreds of times different from the more than 1,000 kilojoules of the monster's flame, but the difference in the direct contact area between the two is more than a thousand times?

The core contact area of ​​the 12.7mm psychic armor-piercing projectile is only 0.11 square centimeters.

Before our gun came out, the most famous Barrett in the world had only 2687 joules, which is two thousand joules of armor-piercing kinetic energy. "(For the sake of explanation, Bartley's muzzle kinetic energy is claimed to be 30,000 joules, but the muzzle kinetic energy = the kinetic energy gained by the bullet + the kinetic energy gained by the firearm + the energy gained by the gas + the energy of the gunshot, so it cannot be benchmarked)

At this time, Lin Ziming, who had remained silent except for mentioning Lin Li once, suddenly raised his hand and asked:

"Academician Tang, I almost understand the principle, but I have a question.

How did you achieve this speed while the bullet was flying? What kind of detonator would do this? "

Lin Ziming's question was very pointed, because the bullet's flight time is very short, and it is absolutely difficult to get it to accelerate twice in such a time.

This technology is not so exaggerated as to be comparable to nuclear fusion. After all, the standard concept of a nuclear explosion is an explosion of one millionth of a second. The acceleration process of a bullet's flight is at most two hundredths of a second and one fifth of a second. Seconds, it is not difficult to do it with current technological means.

But if it can be done, it can be done, and those technological means require a lot of detonating doses.

At least according to Lin Ziming's knowledge, there is currently no detonator that can increase the momentum of a bullet eight times the size of a button battery, not even liquid detonators.

Tang Pin did not speak this time, but used his thumb to unscrew the warhead and held it forward:

"Guess what this is?"

Lin Li and the other two looked forward and saw some tiny white particles scattered in the warhead.

To be honest, Lin Li's first reaction when he saw these particles was alum, but he quickly rejected this guess.

At the same time, a bolt of lightning suddenly flashed through his mind, and his lips began to tremble slightly:

"A lot of energy, a lot of energy, is this a monster crystal?!"

"That's right, it's the Monster Crystal!"

Tang Pin gave him a thumbs up and said with emotion:

"According to our research, the aura crystal will provide a large amount of energy at the moment of gasification - the energy in the Great Mo Realm is conserved, that is, from a reverse perspective, the solidification of aura also requires a large amount of energy.

This kind of energy belongs to beta-type energy, which is a category that can only be observed and cannot be used temporarily, because their eosta plane is uncertain - that is, the seventh side of the crystal. There are similar crystals on the earth.

So far, we can only use it on psychic bullets on a very small scale. Any amount exceeding 3 milligrams will cause it to be disordered, that is, it will not be able to vaporize after more than 3 milligrams.

Even if they are grouped according to measurement and then gathered together across the equipment, the minimum separation distance must be two meters. This may involve some kind of microscopic state problem, which is similar to the penetrating properties of neutrinos.

In short, they are aggregates similar to many local microscopic properties. The physics team is currently studying other applications of monster crystals. At this stage, our 12.7mm psychic armor-piercing bullet is the only mature result. "

Lin Li is not a molecular expert, so he doesn't have a clear understanding of what Tang Pin said. He is more curious about another thing:

"Academician Tang, what level of monsters or practitioners can a 12.7mm psychic armor-piercing bullet kill?"

Tang Pin flipped through the report in front of him, handed one page to him, and said at the same time:

"According to our actual combat testing, the current killing limit of this armor-piercing projectile is

In the early stage of the third level, it is the target of the first and second levels of the Dan Formation Realm, and the opponent cannot hide within a thousand meters.

Because their spiritual perception feedback cannot make the body react so quickly.

But it’s hard to say about two thousand meters.

Practitioners above the eighth level of foundation building can basically avoid it, and the fatality rate below the eighth level is about 85%, but this is already several times more effective than our previous firearms. "

Lin Li nodded slightly when he heard this, with excitement in his eyes.

As Tang Pin said, although the rabbits' previous firearms could kill practitioners on the sixth level of the Foundation Establishment Realm, the muzzle velocity of those bullets was only more than 800 meters per second, which was one-fifth of today's new bullets.

Therefore, except for practitioners who are trapped in a specific area, the original bullets can only stably kill practitioners on one or two levels of the Foundation Establishment Realm within 500 meters. If they encounter extreme defense, they may not be able to hit them.

It is possible to kill practitioners on the sixth floor of the Foundation Establishment Realm within two hundred meters, but for practitioners, a sniper rifle with a range of 200 meters is already useless - at this distance, either the opponent will be killed by a close-range anti-aircraft gun, or he will be killed first. Rush into the position in one step, causing a huge wave of damage before dying.

Regardless of the above situation, the original sniper rifle cannot exert its effect.

It is a positioning that you can use, but there are many more useful and convenient things than you.

But this kind of psychic armor-piercing bullet is different. The peak speed of 4100m/s can kill almost any cultivator or monster within the third level within a thousand meters. This improvement is more than several times?

Then Lin Li looked at Lin Ziming and said:

"Colonel Lin, how are you? Are your eyes burning? Do you want to have sex?"

Although Tang Pin didn't say it directly, he took Lin Li and Lin directly to the shooting range today instead of the laboratory to look at the data. The underlying meaning was already very clear.

This also proves Tang Pin's confidence in this firearm and the new 12.7mm psychic armor-piercing bullet.

After hearing Lin Li's words, Lin Ziming's face showed a rare look of expectation.

As a soldier, who doesn’t love knives and guns?

In fact, he was a little impatient when Tang Pin was introducing firearms. If he couldn't keep them all in GTA5...ahem.

Tang Pin obviously saw Lin Ziming's urgency and handed him the gun with a smile:

"Colonel Lin, hold on tight. It weighs more than twenty pounds."

Lin Ziming carefully took the js05 and pressed it against his chest. Although he had used many sniper rifles, this was the first time he had used the js05, which was specially designed for the west:

"Good guy, it's really not light."

Then under Tang Pin's guidance, he inserted the bullet into the calibration and walked from the gun storage platform to the test firing platform in the shooting range.

Since Da Mojie does not need to consider the issue of building density, the military base designed the shooting range to be very open during construction, with a diameter of nearly three kilometers and complete functions.

At this moment.

On a high platform one kilometer away from the test launch platform is the remains of a monster beast, which is at the early stage of the third level.

Although the dead monsters do not have spiritual energy to protect their bodies, their bones are many times stronger than their surface defenses.

After everything was ready, Lin Li took the gun and hit the target.

As the captain of the special operations team, he is extremely proficient in this type of firearm. When ready, he lay down on the ground, aimed at the target, and pulled the trigger.

Bang——

JS05, which had no silencer equipment, let out a roar, and the powerful recoil force made Lin Ziming, a practitioner at the second level of Qi training, unable to hold on, and his shoulders sank heavily.

By the time he came to his senses, the skeleton of the demon beast one kilometer away had been shattered by the armor-piercing power.

Lin Li on the side was stunned for a few seconds when he saw this, and suddenly turned to Tang Pin and asked:

"Academician Tang, how many rounds of this kind of psychic armor-piercing bullet can be made from one monster crystal?"

Tang Pin thought for a while and said:

"About two hundred rounds. After all, the quality of the monster crystal itself is not heavy. Moreover, its interior is not entirely composed of spiritual energy crystals. There are also some other ingredients."

"One level 3 monster crystal can produce two hundred rounds of 12.7mm psychic armor-piercing bullets. One armor-piercing bullet can kill a level 3 monster."

Lin Li whispered softly and looked at Lin Ziming, and their eyes lit up at the same time.

This is the two-in-one update today. I am revising the article because of my headache. Please give me some monthly votes.

Then some students seemed to have misunderstood. I was not talking about the emojis urging updates, but some comments asking why updates were not added.

That TikTok is quite interesting. I even grabbed the first floor a few days ago.
