Although the distance between the two sides at this time is still as much as one astronomical unit. The distance of one astronomical unit seems very far away. If ordinary energy weapons are used, it is impossible for the civilization of the earth to reach such a far distance. For example, the civilization of the earth

Even with the rapid development of science and technology of earth civilization in recent years, the laser weapons of earth civilization have already surpassed the period of previous years. However, at this time, the laser weapons of earth civilization are effective, and the attack range is only 20,000 to 300,000 kilometers. As for other

Energy weapons have a shorter range.

In fact, not only the range of the earth's energy weapons can only reach 20,000 to 300,000 kilometers, but the attack range of the energy weapons on these spacecrafts of the opposing civilization's fleet will actually not exceed 500,000 kilometers. After all, the opposing civilization is also at this time.

It's just around level one civilization, so its attack range isn't much greater than that of humans.

However, weapons such as electromagnetic railguns, which rely purely on physical attack and rely on pure speed, are different. No matter how far away they are, they can still attack. However, if the distance is too far, such as several astronomical units away,

At that time, even if these electromagnetic rail gun shells used guided shells, it would be very difficult to focus on the opponent.

After all, at this time, the fastest speed of the projectiles fired by the electromagnetic railgun of human civilization is only about 1% of the speed of light.

Following Dong Xiaoming's order, the electromagnetic railguns on the spaceships fired the first shell and then immediately began to fire the second shell. Ten seconds later, the second shell came from the barrel of the electronic railgun.

It shoots out, the red light flashes, and then quickly disappears.

Of course, this does not mean that these electromagnetic rail gun shells have really disappeared. This is because when these electromagnetic rail gun shells accelerate in the electromagnetic rail gun tube, due to the double layer of energy and friction, the electromagnetic rail gun

Only the cannonballs turn red, but when these cannonballs are fired, they cool down immediately. After all, the background temperature at the edge of the solar system is very low and very dark, so the existence of these cannonballs cannot be seen.

Although the projectiles fired by these electromagnetic railguns are not very large, with the largest being only twenty or thirty centimeters in size, once they are hit by these battery railguns, the destructive power produced is extremely huge.

You must know that the material used in these electromagnetic railgun shells is the hardest metal currently smelted by human civilization. Its hardness is even harder than diamond. At the same time, the density of these shells is also very high, although these shells are the largest in size.

It will not exceed 30 centimeters, but the weight of a 30-centimeter artillery shell is at least 300 kilograms. This is still inside these artillery shells, not really solid. After all, these artillery shells are also equipped with a guidance system and a miniature jet system.

The steering system of artillery shells.

Therefore, once it is hit, the destructive power produced is very amazing. Even those asteroids with a slightly larger mass are enough to shatter these asteroids into pieces once they are hit by the shells of these electronic rail guns.

Half an hour later, the flying fish fleet of human civilization began to stop firing the electromagnetic rail gun shells. Of course, this was not that the flying fish fleet of human civilization wanted to stop firing shells, but after more than half an hour of firing, the fleet

The barrels of the electromagnetic railguns in these spacecrafts are already very hot. If they continue to be fired, it will have a destructive effect on the barrels of the electromagnetic railguns, and may even directly burn the barrels and electricity of the electromagnetic railguns.

supply system.

Therefore, at this time, the first wave of attacks by the flying fish fleet of human civilization has finally ended. The second wave of attacks must be carried out after the barrels of these electromagnetic railguns have cooled down. The cooling time must be at least two hours, so here

Within two hours, everyone in the Feiyu Fleet could only wait patiently.

In fact, the soldiers within the Feiyu fleet were very nervous at this time. You must know that human civilization has already launched an attack on the other side, so they do not know at this time whether the other side's fleet has already launched an attack on them, or has already launched an attack on them.

has launched an attack on them, but the spacecraft of human civilization did not detect the opponent's attack.

"Each ship will immediately report the situation to the other side. Have you found out whether the other side is attacking us?" Dong Xiaoming gave the order with some worry.

"Sir, we have not found any signs of the other side's fleet attacking us, nor have we found anything unusual about the other side."

"No abnormality was found on our ship."

"..."

As each spacecraft reported, no abnormality was found in the opponent's civilization's fleet. This made Dong Xiaoming a little confused. Knowing that the opponent's civilization was already a first-level civilization, could the attack range of the opponent's civilization be even one

The distance in astronomical units has not been reached?

However, he continued to issue orders for all spacecraft in the fleet to continue firing the second wave of shells after the electromagnetic railgun cooled down.

Subsequently, every one or two hours, the flying fish fleet of human civilization will launch a large number of electromagnetic railgun shells in the direction of the opponent's fleet.

………

"Reporting to the commander, we have discovered that there is an abnormal situation in the human civilization fleet. The opponent's civilization fleet will have a large amount of energy overflow every one or two hours. However, the reason is not yet known." At this time, the reconnaissance fleet of the rat civilization also

An abnormal phenomenon was discovered when the fleet of human civilization launched electromagnetic rail guns.

After all, when the fleet of human civilization launches the electromagnetic rail gun, not only the speed of the spacecraft will be greatly reduced, but also when the electromagnetic rail gun is launched, a large amount of energy will leak out, so these situations have been eliminated by the rat civilization.

Detected.

Although their civilized reconnaissance fleet has detected these abnormal situations in the human civilization fleet, the commander of this fleet does not think that human civilization is attacking them at this time. After all, in his subconscious, human beings

The civilization's technology is definitely not comparable to theirs, so the attack range of the opponent's energy weapons is definitely far inferior to theirs.

At this time, he did not realize at all that the main attack method of human civilization at this time was not energy attack method, but other attack methods, such as purely physical attack methods such as electromagnetic rail guns.

After all, in the early years of human civilization, when the earth's civilization was still in the period of intraplanetary civilization, the attack methods used were naturally physical attack methods. After all, energy attack methods such as laser weapons could not be used in the atmosphere.

, the energy decline will be very severe, and it will be impossible to carry out effective long-range strikes, especially in bad weather conditions, and it will not even be as good as ordinary weapons, so it will naturally not be favored by everyone.
