Half-immortal civilization

About 5000 billion kilometers away from the side of the Nanmen galaxy, there are thousands of large and small spaceships floating here; and now the number of these spaceships is still increasing!Here is the position of the spectator representative.Some of them are from the imperial kingdom, some are from representatives of business groups, and it is not even ruled out that there are star thieves.

In this war, the spectators still strictly abide by the default rules. The largest spaceship is only 100 kilometers away, and it is an ordinary spaceship.

However, with a distance of 5000 billion kilometers, it can only be said to be relatively safe, not completely safe.Around the solar system, the distance between stars is about four light years, and one light year is about 9.5 trillion kilometers; but in the Pearl Star Field, such as the Four Empires, the distance between galaxies is about two trillion kilometers , in the periphery of the Mingzhu starfield (near the Nanmen galaxy), the distance between galaxies does not exceed five trillion kilometers; the gravitational influence range of galaxies can reach a maximum range of four to five light years, but the core influence generally does not exceed 3000 billion kilometer.

// @.s.?? It can be seen that the distance of 5000 billion kilometers is in the galaxy, just like being at the door of the house, so it is not absolutely safe.But watching the battle group itself is a risky industry, and it can't be too far away!Detectors flashing photoelectric information were distributed around, and then slowly flew forward.This is an instrument used to capture space combat information. In order to prevent misunderstanding, it has to be specially marked.Of course, during the battle, no one will pay attention to it, and it will be lost if it is destroyed; everyone can only say, try to express: We are playing soy sauce; the spectator group must have the awareness of the spectator group.And this time.The fleet of the Tianyun Empire has already traveled more than half of the distance, and it is still one light-year away from the humans on Earth.But along the way, the princes and generals of the Tianyun Empire, even the soldiers, were all extremely distressed. Everyone knew the tactics of humans on Earth, but they were really helpless!Tried many ways, but still can't work!
"Your Highness, as of now, 300 warships with a distance of 2000 kilometers have been wiped out. [-] small warships; but the opponent's attack has not stopped. On the contrary, after getting familiar with our attack methods, etc., the loss has become less and less. , the harassment of us is getting more and more serious!" The adjutant's face became thin.This is a recent disturbance!

"So many have been wiped out. Are you still not retreating?" The First Prince was also a little thin.During this period of time, all the soldiers of the Tianyun Empire did not have a good rest; they would be woken up by the alarm from time to time.Then he woke up like a conditioned reflex, and immediately sat down at his post.

To be honest, even though he is standing in a hostile position, the First Prince admires the courage of these earth warriors; in space, these earth humans have no backup, and they have to maneuver, so once the spaceship is destroyed , then only face death!And the most important thing is that no earthlings have been captured yet.An important reason for this is that without the protection of the spacecraft, intelligent life is too small in the universe, it can only live for a dozen breaths!Moreover, these earth humans have a strong will to die, and some even pull out the pistols on their waists to commit suicide.Suddenly, the deputy thought of a possibility, "Your Highness, the humans on this earth have been harassing us all the time. In addition to the harassment, are they also detecting our fighting methods?"

Um?The eldest prince was terrified!

Then as he imagined, he became more and more sure of the problem that the deputy found!Yes, judging from the current situation, humans on this earth are really cunning and cunning. Every time they do something, they must have several goals!But now, to be able to persist in not flinching despite such a serious loss, maybe there are other more important tasks besides courage!

As for this mission, [-]% of it may be to constantly test the attack methods, attack methods, defense methods, reaction speed and so on of Tianyun Empire.

The more he thought about it, the more gloomy the eldest prince's face became, because this thought and guess were so reasonable!No reasonable doubts are allowed!In war, the reaction speed of warships is an absolute military secret!

"Hmph!" The eldest prince snorted angrily, it was too late to say anything at this time, and the continuous harassment for more than a month had already exhausted the possible means of the Sky Cloud Empire.

However, there are still some things that the Tianyun Empire did not expect...

At the same time, on the earth side, in bright scientific laboratories one after another, scientists are busy busy.

"All the shells of the rail guns should be replaced with self-destructive shells! All quantum foam bombs are set with automatic destruction programs." Zhang Wanfei is inspecting the main control center of the starry sky cannon.

"Your Majesty, it has been set up. The effective attack distance of all railgun shells is one light-year, and if it exceeds one light-year, the gunpowder inside will explode and become debris.

And quantum foam bombs too.

As long as they fail to hit the target, all shells will be automatically destroyed at a distance of one light year. "The old scientists are full of confidence.

Zhang Wanfei nodded, a trace of helplessness flashed in his eyes.The reason is simple. Because the railgun is a moving solid projectile, there is no problem of energy loss in the universe; on the contrary, if it is affected by the gravitational field of the planet, the speed will even increase.Under such circumstances, if there are no restrictions, it is very likely that after many years, these shells may run into the territory of the four empires under the influence of the black hole!
You must know that the location of the South Gate galaxy is on the outer periphery, while the Tianyun Empire is on the inner periphery; therefore, the attack direction of the humans on Earth is towards the interior of the Pearl Starfield!
"Your Majesty, the information sent from the front has been able to roughly determine the opponent's position, and we can implement an early strike strategy!" Zhang Wanfei shot a ray of light, and finally condensed into a figure.

"How about the losses at the front?"

"It's within the plan. The soldiers still refuse to return."

"Well. Everyone is responsible for the rise and fall of the world. Let them fight with peace of mind." Zhang Wanfei sighed, and understood and admired the mentality of the frontline soldiers: their hard tasks have been completed, and the rest are free tasks.

Zhang Wanfei turned his head.Nodding to the old scientist, "Old Chen, let's launch."

"Okay!" The scientists at the scene did not have the tense atmosphere of the upcoming battle, but they were all very excited!Perhaps, for them, this is just a somewhat special scientific experiment.However, this experiment will face more than 5000 million elite troops of the Tianyun Empire.

The Sky Cloud Empire didn't know yet that the humans on Earth were already preparing to attack ahead of time, a light-year away.

This cannot be blamed on the Tianyun Empire's carelessness, there is a reason for this.The full radius of influence of a star system.It is very likely to reach the influence range of two or three light years or even further four or five light years; but the stars in the Pearl Star Field are very "crowded".This leads to a variety of complex cosmic space environments. Gravitational fields of different sizes and strengths act in space, superimpose each other, and have the influence of black holes.Plus the universe itself is in constant motion.What ultimately leads to is.The space of the Pearl Star Field fluctuates greatly, and there is also a slight gap in time, which makes ultra-long-distance locking almost impossible.because.Maybe the position you calculated a moment ago will change the next moment!
At a distance of one light-year, even light takes a year to travel; such a long distance, a deviation of one or two seconds is really normal, and the deviation may be an hour.And one second is a deviation of 38 kilometers!

Of course, things are not absolute. If you use coverage attacks, there is still a certain degree of danger.Therefore, the Tianyun Empire's fleet moved forward very carefully.

But the Sky Cloud Empire has never imagined that the small special forces on the earth, in addition to harassment, detection and attack methods, etc., have been locating the location of the Sky Cloud Empire's fleet for a month, and have also analyzed their fleet for a month Movement rules, etc.

All of these actions made it possible for ultra-long-distance locking attacks to be more precise!
Perhaps the error will still be large, but it is no longer a random attack like a headless fly.

In fact, there is another thing that made the Tianyun Empire careless: the previous wars in the Pearl Starfield, etc., were mainly energy cannons, but energy cannons will automatically dissipate in space; they are not like rail guns, which can theoretically move unlimitedly go down.Such a mindset, to a certain extent, limits their consideration in a certain aspect.

In the South Gate galaxy, three thousand rail guns began to recharge, and in an instant, lightning flashed. Blue, white, red, and purple lightning and brilliance were like dragons, winding around the rail guns that were tens of thousands of kilometers long. Go up; turn each rail gun into the most brilliant treasure in the world.

Well, maybe for the humans on earth, this is indeed a treasure, a treasure related to the destiny of the nation.

The spectator group from afar received the message immediately, and everyone's eyes widened, even the spectator groups from the Four Great Empires!Everyone has railgun technology, but every person, country or race wants to see how humans on earth use railguns!In fact, the rail guns with a length of tens of thousands of kilometers have already made the eyes of all empires shine!The original outline said, but it doesn't mean it can be mastered!
In a technological society, there is no useless technology, only useless technology in the right place!There are only technologies that have not been developed to the extreme.Obviously, the rail gun is one of the pinnacle products of electromagnetic technology; and the rail gun with a length of tens of thousands of kilometers is the pinnacle product of the rail gun technology series!
The charging time has been consumed for two full days... Humans on Earth will not tell you that we are hiding our clumsiness!Since time is not very tight, humans on Earth are willing to hide their tricks!

There is a little advantage in hiding a little; if in a more intense battle, the rail gun suddenly completes charging within a few hours, it may seriously disrupt the enemy's war deployment.

After waiting for 50 hours, the charging was over, and the railgun finally experienced a qualitative change. The lightning bolts were like thin silk threads, hovering finely on the surface of the railgun, allowing the railgun, which is tens of thousands of kilometers long, to At this moment, it seemed to turn into a crystal clear crystal column, which gave people a crystal clear, warm feeling like suet jade.However, this crystal pillar is not only beautiful!

At a certain moment, the engine behind the rail gun started, and hazy water vapor sprayed out, and the rail gun moved forward slowly. After reaching a certain initial speed, the rail gun finally started!
But I saw a series of shining beams of light flying for millions of kilometers, and then dissipated; but in the process of spraying, railgun shells, large and small, had already disappeared in space with a howl.

At this time, the rail gun body also retreated suddenly under the huge reaction force...

The engine roared, and the rail gun was readjusted, and it was already a week later.

Accelerating a static cannonball directly to 0.7 to 0.8 times the speed of light is not a simple matter. The long charging time and huge reaction force, as well as the inflexibility of the star cannon itself and the week-long re-adjustment Time is a disadvantage.

Such a situation made many military staff officers in the spectator group heave a sigh of relief, but at the same time felt a little helpless.

Obviously, the rail gun is stronger, but it is very inflexible.Such a starry cannon seems a little insufficient for defense, let alone for offense.That's why I was relieved.

But I have to say that such a huge cannon is really shocking.Accelerating an object directly from zero to a few tenths of the speed of light, such a technology, is also very promising.For example, the staff officers of the four great empires thought that such a giant space cannon could be used as one of the main artillery technologies in the huge space continent!
