At the edge of the jungle, on the branches of a large tree with lush foliage, Ye Feng, whose whole body was covered under the camouflage net, was concentrating on the pattern depiction of the anti-materiel sniper warhead.

The carving tool in the hand is a dart blade used for tactical throwing, with a fusiform appearance and excellent hardness.

At this moment, Ye Feng's expression was extremely focused, he held the anti-weapon sniper warhead in his left hand, and the dart blade in his right hand, and was extremely careful to carve a spiral-shaped ballistic pattern on the warhead.

Since "The End of the World" claims to be 99% real experience, Ye Feng will think of using the way of depicting lines to increase the effective shooting distance of bullets.

He had done countless bullet pattern experiments in the real world, and finally at the heavy cost of more than 500 guns, the consumption of tens of thousands of bullets, and the angry eyes of the instructor who were about to erupt into fire, he finally mastered the skill of bullet pattern depiction.

The process is very difficult, because the caliber of the bullet is different, and the number of lines depicted will be different.

FOR EXAMPLE, THE 5.56MM BULLET CAN WITHSTAND TWO LINES OF DEPICTION, AND THE FORM OF THE LINES CANNOT TAKE A SPIRAL, ONLY FLOWING WATER.

The 7.62MM bullet can withstand the depiction of three lines, and the form of the lines can be flowing and spiraling.

12.7MM BULLETS, IT CAN WITHSTAND FIVE STRIPES OF LINE CARVING, AND THE PATTERN FORM MUST BE SPIRAL.

Each caliber of bullet must be in accordance with the corresponding pattern characterization rules, only in this way can we ensure that the warhead will not be twisted and exploded due to air friction during flight.

The first anti-materiel sniper bullet is portrayed, with five spiral lines, evenly spaced, and it looks like a fine industrial work of art, which is pleasing to the eye.

For the sake of safety, Ye Feng took out a second anti-equipment sniper bullet and portrayed it.

Why is it that the warhead is engraved with a pattern that increases the effective range of the bullet?

At this moment, you must have the above questions in your mind.

This has to talk about the principle and basis involved in the flight of the bullet.

Aerodynamics!

What is aerodynamics, which is defined as the force exerted on an object moving in air, proportional to the square of the object's velocity, the characteristic area of the object, and the density of the air.

The density of the air, Ye Feng can't change it, but he has a way to change the characteristic area of the object and the speed of the object's movement.

Reducing the characteristic area of the warhead is achieved in the process of pattern characterization.

Second, the spiral stripes carved on the warhead completely match the direction of the warhead's flight rotation in the air, thereby reducing air resistance and adding rotating airflow propulsion.

In short, it is a warhead with a depicted pattern, which flies faster and has a longer effective range.

However, after the pattern is depicted, the warhead itself is greatly reduced due to the reduction of weight, and the stability performance is greatly reduced, if the warhead texture is not very accurate, then the warhead is very likely to explode when the firing pin hits the bullet fuse, commonly known as human factor explosion.

It is not difficult to see that if you want to increase the effective range of bullets, you can't do it without a pair of skillful hands and a bold and meticulous heart.

Two anti-materiel sniper warheads, carved down the lines, Ye Feng's forehead, a few drops of crystal sweat appeared, he raised his head and looked at the sky in the direction of the ninth war zone.

"It's coming!" Listening to the sound of the propeller wind blowing that was getting closer and closer, Ye Feng did not hurry or slow to load the two sniper warheads with carved lines into the magazine, and immediately entered the sniper field of vision.

In the unobstructed blue sky, the Camanche helicopter gunship slowly flew towards the jungle.

At an altitude of 3,000 meters, it is absolutely safe to fly and combat distance.

In the cockpit of the engine room, the mood of the entire crew was gloomy, and intelligence came from the rear of the troops, and the two scouts in the team disappeared into the jungle.

The disappearance of the scout means that there is an enemy in the jungle. However, as the vanguard and with the advantage of aerial reconnaissance, he did not find the enemy situation in the jungle, so he let two of his scouts disappear into the jungle and their whereabouts are unknown.

The investigation of responsibility is caused by the unknown investigation of the Carmanche crew.

"A swarm of ants, you will know in a minute, what is a real aerial firefight!" The two scouts who disappeared made the pilot's mood extremely irritable.

"Boss, I suggest you fly higher, it's safer." The crew member reminded.

"That's it." The pilot replied in a tone of non-deniability. The altitude of 3,000 meters is the best altitude for carrying out ground strikes, and if it is a little higher, then the output damage of air firepower cannot be accurately guaranteed.

What's more, the effective range of the second-order anti-materiel sniper rifle is about 2,500 meters, and the Camanche does not need to fly a little higher.

"Ahead into a pseudo-hilly terrain, the highest point is 125 meters above sea level." The crew members informed about this height.

Soon, Camanche flew over the pseudo-hilly terrain and approached the edge of the jungle.

That's just at this time.

Bang~!

The sonic boom suddenly rang out, and the alert pilot, somewhat stunned, saw the edge of the jungle flashing a blue line of fire.

"Blue Line of Fire?" The pilot couldn't help but sneer in his heart. I met another rookie killer who didn't understand the performance of firearms.

The blue line of fire, the hallmark of a second-order modified weapon, will not be able to hit an unexpected target at 2,800 meters, even with the longest range.

Is this an attempt?

However, the pilot, who despised the pilot for no more than the blink of an eye, was stunned in the cockpit in horror for the next second.

Clang~!

What made him unbelievable was that an anti-materiel sniper bullet actually hit the Wuzhi glass in front of the pilot's eyes, although the bullet did not destroy the Wuzhi glass in the first place, but it made the glass appear like a spider's web.

That's 3,000 meters in the air!

How could a second-order anti-materiel sniper rifle have such a long range!

In the midst of this confusion, the pilot heard another explosion, faintly heard.

Bang~!

By the time he reacted slightly, the second anti-materiel sniper bullet had already landed on the Wuzhi glass, and the worst thing was that this sniper warhead had pierced through the glass. And at the same time as the hole, the warhead exploded.

The fragments of the warhead were splashed into the entire cockpit in an instant, and the pilot had no way to escape, and he was shot in the head on the spot.

The main pilot loses control, and the co-pilot takes over control of the flight.

But at the time of the handover of the main and vice, Camanche, who temporarily lost control, fell sharply downward.

Within 2500 meters!

Bang~!

Ye Feng pulled the trigger again.

Bang~!

Battle Regulus also pulled the trigger.

As a result, two anti-materiel sniper shells, dragging two long blue tail flames, whistled towards Camanche's tail and front, respectively.

Bang~!

The sniper bullet that hit the fuel tank of Battle Regulus exploded. Then I saw that in the sky, Camanche began to fall with thick flames and black smoke.

"Hit, shoot down." The observer of Battle Regulus informed this exciting news.

Warzone Announcement: Congratulations to Battle Regulus for successfully shooting down a Camanche gunship, thus earning the Blue title of [Air Killer].

The announcement of the war zone that showed his face and the supreme blue title honor obtained by destroying Camanche could not make Battle Xuanyuan's face appear with joy, even a hint, at this time, his heart was full of doubts.

It's also a second-order counter-weapon, why can the blood mist hit targets outside the effective range?

"You say, why can the second-order anti-equipment in the boss's hand hit a target three thousand meters away, can't it be open?" Battle Xuanyuan, who couldn't think of an answer, began to think crankily-

Rushing back to the memories of Tianding on the jungle road, looking up at the sudden announcement of the war zone, he couldn't help but breathe a sigh of relief, and rejoiced in his heart that the Camanche was fortunately beaten down by Battle Xuanyuan.

It's just that what makes him quite puzzled is when did Battle Xuanyuan's sniper marksmanship become reassuring?

On the side of the subordinate forces, when Camanche's signal disappeared from the ranks, the face of the battle captain couldn't help but be gloomy.

Before seeing the enemy, their side lost two scouts and a Camanche helicopter gunship, especially the latter, whose strategic value is second only to biological and chemical weapons, was actually beaten down by a group of survivors in the ninth war zone, which is distressing and tricky.

"All members, listen to my command, activate the source of the virus in the body, equip the exclusive weapon, and let's fight into the jungle together." With a stroke of thought, the captain summoned a huge supply crate containing melee weapons.

The supply box opened, and a blood-colored fire axe with a total length of seven meters appeared in the combat captain's hot eyes.

A weapon with a total length of seven meters, and an action captain who is less than two meters tall, the gap between the two is not a star and a half, how can the action captain afford such a long weapon?

Soon, the battle captain proved that he could afford it.

The combat captain who activated the origin of the virus and completed the alienation suddenly increased his height to six meters, becoming a giant zombie, and at this time, he calmly walked to the supply box, bent down and reached out, and grabbed the giant blood-colored fire axe that was seven meters long.

The battle captain swung the giant blood-colored fire axe, and behind him, twenty giant zombie members holding various weapons also waved their weapons.
