Lin Kai followed closely behind He Jun, but he didn't expect He Jun to stand suddenly after going out, and Lin Kai, who didn't have time to stop, bumped into He Jun's back: "What are you doing?" Why do you stop it? ”

"It's okay, something suddenly occurred to me. Pen? Interesting? Pavilion wWw. ｂiquge。 info" He Jun said, "Follow me!" ”

Lin Kai didn't know what medicine He Jun was selling in the gourd, so he followed behind He Jun in a daze.

The two left the core of the city and plunged into the concrete jungle again, but in the opposite direction.

When he walked to the edge of the city, the road was broken, and more than ten meters ahead was a heavy rock wall, and it was only at this time that He Jun adjusted his direction and traveled along the rock wall to one side.

After walking around the city for a small half circle, there were rows of passages leading to the top floor in front of him, He Jun turned around and walked back, and after returning to the origin, he walked seven or eight hundred meters in the other direction, and saw an unusually huge passage on the rock wall, and there were two faded characters above the passage: Exit!

In the exit is a wide road large enough for four cars to run in parallel, there are pillboxes on each side of the entrance, and there are several underground bunkers, and if you look closely, there are the remains of the dead in the bunkers and bunkers, and there is a large machine gun with an avant-garde shape on the firing hole of one of the bunkers.

Lin Kai's eyes lit up when he saw the gun, and he walked into the bunker to see it clearly, but he didn't expect that he only took one step, and there was a roar of bullet casings all over the ground under his feet.

The two of them were stunned at the same time, what is the situation?

Although I don't know what era this place belongs to, it is an indisputable fact that the level of science and technology is higher than that of the 23rd century, but mankind in the 23rd century has begun to eliminate gunpowder weapons, and the barrel of that machine gun is thick and long, which looks like an electromagnetic weapon, and where did the bullet casings on the ground come from?

Lin Kai glanced around, casually pulled out a rifle in the arms of the skeleton, shook it vigorously to shake off the bones on the gun, and carefully looked the gun up and down.

This look out of the doorway shows that this gun is a stockless structure with a magazine stuck on the butt, but it is a little longer than a rifle with a stock. The pull handle and the casing window are above the butt, but the strangest thing is that there is a long battery box behind the magazine!

This thing Lin Kai is too familiar with, it is the place where the white battery is installed on the electromagnetic rifle. With a press of the finger, a standard-sized white battery jumped out.

But the electromagnetic rifle doesn't need to be loaded at all, and there is no need to throw the shell, what are the two things on it for?

Lin Kai directly handed the gun to He Jun: "Brother Jun, look at this gun." ”

Perhaps because the environment here is relatively dry, He Jun took it and fiddled with it a few times before successfully disassembling the gun. He actually pulled out a finger-thick barrel from the fist-thick electromagnetic accelerometer!

"I'll go, electromagnetic gunpowder double acceleration?" He Jun immediately understood the principle of this thing.

Lin Kai suddenly realized, picked up another and fiddled with it happily.

Although he lacked theoretical knowledge, he was well versed in the principles of firearms.

One of the major drawbacks of the electromagnetic rifle is that the bullet in the chamber must accelerate from zero, and the acceleration of the bullet directly determines the speed of the chamber, affecting the final power of the bullet!

To achieve a higher muzzle velocity, the barrel must be lengthened.

However, the barrel is not something that can be added, a longer barrel does bring a higher muzzle velocity, but a longer barrel can bring a series of practical problems.

For example, it is troublesome to carry after the gun is lengthened, the manufacturing process of the gun barrel needs to be improved, how to ensure reliability, maintenance is more difficult, and even the power consumption will increase dramatically due to the lengthening of the barrel.

Therefore, the barrel is not just added to the barrel. It is important to strike an acceptable balance between the weapon's power, overall gun length, reliability, maintenance, and power consumption, with reliability being the most important of all, even at the expense of other aspects of performance.

That is, military firearms are not the best weapons, but the product of a compromise.

The 23rd century is when electromagnetic weapons have just begun to enter the stage of practical use, and the dispute in the weapons community over whether electromagnetic weapons can replace traditional weapons has never subsided.

In terms of He Jun's personal experience, this electromagnetic rifle does need to be improved. For example, after the bullet is loaded into the chamber, it must be energized all the time to ensure that the bullet is suspended in the chamber; Another example is that the recoil is too strong, and it cannot be used without wearing power armor.

At present, this gun is a combination of traditional firearms and electromagnetic weapons. To put it simply, it is to put a layer of electromagnetic accelerometer on the barrel jacket of a gunpowder rifle!

In this way, the bullet does not have to endure the disadvantages of the muzzle velocity of electromagnetic acceleration when the gun is fired, and the dual effect of gunpowder gas and electromagnetic acceleration can increase the speed of the bullet and greatly improve the power of the weapon.

He Jun couldn't tell what the speed of the bullet out of this gun was. But it would never be lower than five times the speed of sound, and rifled rifles simply could not withstand the wear and tear of high-speed bullets on rifling, so he judged that such a gun must use smoothbore technology, and the bullets used were likely to be dart-shaped with tails.

Unfortunately, there was not a single bullet left in the gun, and he couldn't confirm his guess at all.

In the 23rd century, I had heard of this kind of design, but I had only heard of it, but I didn't expect to see it today.

Using simplified Chinese characters and the concept of white battery plus equipment, He Jun can basically determine that this era should be a certain period of time after the 23rd century, but it is difficult to judge how many years it is.

Thinking of this, He Jun raised his head and asked, "Lao Lin, do you want to go out and have a look?" ”

"Get out? Where to? Lin Kai was stunned.

He Jun pointed to the top of his head: "Of course it's on the ground." ”

"Are you kidding?" Lin Kai kicked the ball of his foot on the ground, and a pile of bullet shells rolled into a pile, "It's not necessarily too peaceful up there!" ”

"I'm serious." He Jun said, "Go, go back!" ”

"Huh?" Lin Kai's mind couldn't keep up with He Jun's train of thought, "Aren't you going out?" How did you change it back again? ”

"We can't go out empty-handed, can we?" He Jun said without looking back.

After more than two hours, the exhausted two people finally returned to the community, and after entering the protection area, they didn't say a word, took off the power armor as quickly as possible, and immediately ate a nonsense meal.

When the two of them were full of water and food, and when they talked about exploring the ground, they were unsurprisingly opposed by everyone.

It's just that this time everyone knows that opposition is useless, and they don't expect He Jun to listen to everyone's opinions at all, just express their respective attitudes.

He Jun didn't plan to set off immediately, even though he was wearing power armor, he and Lin Kai were also very tired, and the batteries were also consumed, so they had to come up with a detailed plan and make all preparations before they could carry out the next step of exploration.

At the very least, all white batteries must be fully charged. (To be continued.) )
