Fighting The Galaxy

Underwater weapons are very different from those on the ground and in space.

Take the oldest gunpowder weapon, the bullet is rotating inside the barrel, even if it is a pistol, the effective range is 50 meters, in fact, it can fly a few hundred meters away, but there is no accurate head. But, this thing, in the water, can only run a dozen meters away.

The bullet is rotating, in the air, to maintain stability, this is the principle of gyro, the rotation can be stable, but in the water, it is the most inappropriate to rotate out, in the water, it can not rotate one meter , It will change from rotating to rolling, and then the rolling will become more powerful, a dozen meters, all the kinetic energy will be lost. Moreover, at this time, I do not know where to go.

Other modern weapons do n’t work either. Laser guns rely on the energy of the light beam to kill them. Even in the cloud and fog, the energy will decay quickly. Once in the water, the attenuation will be faster. In the water Using it, you can see that the muzzle starts to form a tumbling boiling water column, which is the situation under the heat of the laser energy. However, when it is twenty or thirty meters forward, this horizontal water column cannot continue to move forward. , The energy has been used to evaporate the nearby seawater.

As for anti-matter bombs with more energy, etc., if they are used in water, it will not blow up the target, but directly blow up the entire ocean, and countless splashes will be lifted into space, even reaching the first cosmic speed A circle of halo spinning around the planet.

What is the best thing to use in water?

Crossbow arrows, yes, this is the most primitive weapon.

The slender arrows have the best stability in the water, and can easily kill the target at a distance of 50 meters. As long as its initial velocity is large enough, this is enough. As far as 50 meters away?

If you dive, you know that underwater, you can see things 30 to 40 meters away, it is already very good, a range of 50 meters is more than enough.

Of course, with the development of technology, this crossbow can also rejuvenate, for example, it is no longer released by the elasticity of the bowstring. After all, the bowstring is wet when it is underwater, and it will also lose a lot of energy. It can be fired with an ancient gunpowder gun or a modern electromagnetic gun. However, since the launch of the electromagnetic gun requires a relatively long track to accumulate enough speed, an ancient gunpowder gun is more suitable.

The diving propeller held in the opponent's hand is not only used for diving propulsion. At the same time, it is also a small gunpowder gun. At this time, when approaching, I found someone in the elevator here. They were also surprised for a while. I did n’t expect that an accident would happen at this time, but they responded in a random manner and immediately made an attack plan.

"Boom!" The ammunition inside ignited, and when it was fired, it made a dull sound, which was the burning of gunpowder inside, pushing the arrow forward, and the sound that was excited on the side wall of the barrel. . When the arrow flew out of the barrel, the gas of the gunpowder violently bleed outward, and it pushed the seawater near the barrel violently, forming a terrible shield-shaped water wave that spread outward.

If it is in the air, at a long distance, the bullet will arrive before the sound. The speed of the bullet is more than twice the speed of the sound. However, in the water, the speed of the bullet becomes slower, but the speed of the sound is very fast, so, The voice will pass first.

Even if the sound didn't pass through, the water wave driven by the discharge of gunpowder gas looked so magnificent, and of course the opposite could be seen instantly.

Launched an attack on yourself! At this moment, everyone's pupils were enlarged.

Nima, what happened?

Suddenly a few frogmen rushed out. What they said was nothing to do. What was this flying?

If it is an ordinary arrow, it is only used to kill people, and other frogmen without any protection are dried in the water. This is almost the same. These people are in the elevator. It is said that there is no danger to life, but The technology of this era has long allowed even a tiny mosquito-sized drone to be full of threats. This arrow shoots over. If the arrow shaft is filled with super explosives, these few shot arrows Ya, enough to blow them into flesh.

How to do?

Just now, Qin Tian found the frogman coming across from him. He planned to go up, stop first, and then ascend. Only when he reached the sea and the platform, it was safe, but now, he found these shots. When the arrow hit, Qin Tian knew that it would be too late to go up, because the planet is gravitational, and going down must be faster than going up.

These arrows don't know what device they are, but it is certain that it is definitely not a good thing, it is to kill them!

Go down, keep going down! This elevator may be for insurance, not only only the modern buttons, but also the oldest type of operating lever used by the elevator. The oldest elevator actually appeared in the mine and was controlled by the operating lever. Lifting, in essence, is the same principle as the winch.

Qin Tian was too late to press those beautiful buttons. His hand quickly pushed the operating lever, released the brakes of the elevator, and set the above drive motor to an uncontrolled state.

Stopping the elevator is the result of many functions. For example, the motor will slow down and stop, but the stop of the motor does not mean that the elevator is stable. It also needs a brake-like device to control it steadily. Otherwise, it will fall down under the influence of gravity.

Now, this is the state of falling, the state of free fall.

In an instant, everyone's feet felt suspended.

Their feet are still in contact with the floor, but their bodies, like the elevator, are in a state of falling downwards. Although they are in contact, there is no force. At this moment, even all parts of the body do not have any I feel that this is exactly the same as total weightlessness in space.

Someone exclaimed, it was Xiao Dongzi again, this fat guy was the most nervous at this time, completely without the kind of calming self-made at the beginning, his fat, as he lost weight, seemed to be far away from him Go the same.

In fact, most of the spaceships now have artificial gravity, so many astronauts have not experienced the feeling of weightlessness. At this moment, Princess Jingxi feels that her heart is empty, follow, and reach out with one hand, and Her hands were tightly held together.

Don't be afraid, I'm here.
