Double Helix of Dajian Doujin

"Who invited you here?" said the little tailor, chasing away the flies.But the flies did not understand what he said, and instead of dispersing, they found a large number of flies.The little tailor got angry, took a towel and licked the flies. At least seven flies fell to the ground and died, and their feet were still in the air.

"You are very good!" he said... The little tailor quickly cut himself a ribbon, sewed it on, and wrote: "Seven at once."... The giant read: "At once Kill seven of them." He thought that the little tailor would think highly of the little tailor if he killed seven people at once.But he decided to try the little tailor first.So he took a stone and crushed it with his hands until water squeezed out of it.

The giant said: "You are so brave, just do it like me."

"That's all?" said the tailor. "That's so easy." He reached into his pocket, took out the cottage cheese, squeezed it, and the water came out.

The giant didn't know what to say, but he still doubted the little man's strength.So he picked up a stone and threw it so high that he could hardly see it.

"Hey," he said, "just do it, you nasty dwarf."

"Of course, well done," said the tailor. "However, your stone will still fall to the ground. I will show you one, and it will not fall."

He took the bird out of his pocket and threw it into the air.The bird was free, very happy, flew away and never came back. "What do you think of the trick, man?" asked the tailor.

"Your weapons? Are you talking about Lin Yushang's abilities? Even if they are easy to learn, is there time to learn them now? Didn't you just say that the recovery team set off 3 days ago?" Miria felt even more strange after hearing this.

"It's okay, first, it's to learn to use our weapons, not to train you to become a magister of the whole department or the commander-in-chief of the legion; second, if it's about dealing with those few people, just study for an hour." Cortana He replied, "Now, you put this on first." After speaking, Cortana brought out a pair of information goggles from the space backpack and gave it to Miria.

The information eyepiece is the basic information interaction device in the night elf troops. Through the eyepiece, soldiers can obtain a lot of information related to the battlefield.For example, the marking of the enemy's position and status, the marking of the execution target location, the status information of the weapon, etc., these are the same as the helmet display of Thor's Hammer armor.Therefore, the information eyepiece is actually a device that provides information to soldiers without wearing armor.

"Okay, start the system now, and you will see something that would not exist in reality. You can compare the difference between wearing the eyepiece and without the eyepiece. I will mark a target location for you now, and you can go and have a look. "Watching Miria put on eyepieces that look like sports sunglasses, Cortana said.

"Are you referring to the place pointed by the arrow? Do you mean to let me go there?" Miria saw a thick black line descending from the sky on the snow not far away, and there was a circle encircling it pointing downwards. The arrow next to the arrow has information such as the distance in meters.Such a thing is definitely not visible after taking off the eyepiece.

"That's right, this is it, you go over and have a look."

This matter is very simple, and Miria did it without any effort.After that, it is to learn how to open the virtual map and other interfaces.

Interfaces such as maps and task lists can be displayed in a variety of ways. The most commonly used one is to place them in the lower left corner of the field of vision, about 50 cm away from the soldiers (in a standing state, if they are in a squatting or lying position, the distance will be shortened accordingly, so that For operation), they are displayed as translucent squares of different colors, which can be operated with one hand.

There is also a display mode that is placed on the fingers of the left hand. Move the palm to a place about 20 cm away from the eyes, and the desired menu will appear on the fingers.This mode requires two-handed operation, and is generally used for more complex operations such as system settings, and can also be used as a way to display maps or other information.

If the soldier is holding a weapon in his hand at this time, a lot of information will be based on the weapon to form a square window interface.For example, ammunition information, sniper parameters, maps, target information (such as pictures of people the sniper needs to shoot), etc., will be lined up in the appropriate position of the weapon.Take the M109 sniper rifle that Miriya is currently getting as an example. The information of the weapon and ammunition will be displayed on the left side of the rifle, which is the side close to Miriya.Further to the left, a map is displayed.The map can also have two display modes, one is the standard mode, that is, the direction of up-north-down-south, left-west-right-east; the other is matching mode, the direction of the map is the same as the actual direction on the ground, this mode is more suitable Navigation during combat.At the same time, information such as the positions of our personnel and detected enemy personnel will also be displayed on the map.The target information and task list will be displayed on the left side of the map, and all dispatched tasks will be displayed here.There are also temporary interfaces such as video dialog boxes, which will be displayed on top of the above interfaces.

At the same time, the display positions of these interfaces can be easily adjusted, just hold the lower left corner of the window (corresponding to the left hand) and move it.Its position is determined based on the position of the user's head.For example, if the map window is placed 50 centimeters in front of the eyes, when the user looks in other directions, the map will also move accordingly, keeping the position 50 centimeters in front of him.

Compared with the information-based eyepiece, the use of the sniper rifle itself is much simpler.The night elves started to use EXACTO ammunition very early, that is, ammunition for extreme precision missions. Currently, they are generally equipped with second-generation ammunition, namely EXACTO-2 bullets.This is a guided bullet that is guided by a laser designator, which can be carried by a sniper or a drone.The bullet senses the laser light through tiny nano-robots on the surface, which work a bit like the photoreceptor cells of an earthworm all over the body.There are 4 fixed fins at the rear of the bullet, and there is a magic circle on the surface of the fins to heat the air.By heating the air, the air velocity on both sides of the bullet is different (the molecules of the hot air move faster), thus creating the effect of turning.

The second-generation ammunition that Miriya now has is equipped with an ultra-miniature ramjet engine.The biggest problem with the first generation of guided bullets is that turning will consume the bullet's own flight kinetic energy, thereby reducing its power.Therefore, the second-generation ammunition uses an ultra-miniature ramjet engine to provide auxiliary power to keep the bullet almost without reducing its speed during the entire flight.

The biggest advantage of the ramjet engine is that there are no moving parts, which fundamentally avoids mechanical failure.It's just that the ramjet engine can't work at zero initial velocity. Therefore, like many missiles that use ramjet engines in the atmosphere, they first use the rocket engine to accelerate to a certain speed, then start the ramjet engine, and continue to accelerate.But here, through the electromagnetic track on the sniper rifle, the speed of EXACTO ammunition can exceed Mach 6 (2040 meters per second), even the scramjet engine (that is, the ramjet) that requires the highest starting speed The speed of the gas flowing through the engine exceeds the speed of sound, and the difficulty is equivalent to lighting a match in a tornado and maintaining its combustion) and it can be completely ignited and started.This ramjet works at a minimum speed of 6 times the speed of sound, and a maximum speed of 25 times the speed of sound.For the 109 km effective range of a sniper rifle like the M5, if there is enough fuel, the bullet can accelerate almost all the time.

Such ammunition also solves the problem of excessive recoil of high muzzle velocity sniper rifles.Originally, using electromagnetic orbital weapons, it can fire very light ammunition, which is enough power.However, in order to solve the problem of guidance, a series of devices need to be put in, coupled with the devices that produce explosive effects, which itself limits the lightweight of ammunition.Therefore, the final result of excessively increasing the exit speed is that the recoil force of the weapon is too large.When using EXACTO ammunition, the muzzle velocity is relatively low (electromagnetic orbital weapons can easily reach a muzzle velocity of more than 4 kilometers per second), and will not produce strong recoil, but the maximum speed of the bullet can reach about Mach 15. , that is, 5100 meters per second.That is, it has low recoil and high kinetic energy killing effect.

With such ammunition, even a person like Miriya who has just come into contact with a sniper rifle can easily hit a target 3 kilometers away.And all she has to do is align the crosshairs with the target.The scene seen in the scope of the sniper rifle is that, in addition to the normal mode mark (that is, the mark scheme that Lin Yushang saw when using the MA5c rifle), the target is surrounded by red translucent balls. Enclosed, the center of the sphere is the expected landing point of the bullet, usually the head and other vital points, and the radius is the maximum radius that can be corrected by the bullet.As long as the center of the reticle is aimed at the ball and the trigger is pulled, the bullet will hit the target.In order for the sniper to know which target his bullet will hit, the ball of the aimed target will be highlighted.

Such a simple operating system surprised Miriya.Learned all the operations in half an hour.

"Unexpectedly, this matter is so simple." Looking at the big tree that was blown up 3 kilometers away, Miria said, "By the way, there is one more thing I wanted to say just now. The two sides of this gun are Isn't it written?"

"Ah, yes, there are indeed some words written, the right side is Elven language, and the left side is the common language of the continent of Eminor." Cortana hesitated.

"What does that mean?"

"The one on the right is 'Sevenatonestroke.', what does it mean..." Cortana thought for a while, and decided to betray the officer, "It means 'kill seven at once.', the left means 'squeeze one to death. An ant needs two fingers, but a trigger needs only one.'”

"..." Miria was speechless for a while, these two paragraphs were very good and powerful, "This seems to be a mess, is it just a pattern?" Miria said, pointing to the back of the first word on the right.

"Uh..." Cortana finally decided to betray his chief completely, "Actually...it was a fly..."

"..." Miria could only slam Cortana hard with her white eyeballs...

It was years later that Miria knew why there was a fly.Then, silently gave the middle finger to Lin Yushang who was still lying dead.

Joking aside, Miria immediately asked a very serious question.Things like information eyepieces are very fragile.In terms of the fighting situation of the big sword fighters, it is easy to damage.Miria is worried that it will affect the battle at that time.

However, Cortana's answer was just...

"My opinion, as long as you don't hit walls, trees, or mountains, this thing won't break. And our fighting style happens to avoid these things."

"When did I hit a wall, a tree, or a mountain?" Miria felt very strange.

"For example, when it was photographed flying." When the artificial intelligence answered, the expression on the image was serious.It's just that Miria felt that there was a mischievous smile hidden in the corner of Cortana's mouth, so she continued to hit it with her white eyes.

"Don't worry, you won't get close to the enemy during this entire battle."

"I can see it, I just don't understand why you have such confidence."
