About 500 billion kilometers away from the side of the South Gate Galaxy, there are thousands of large and small spaceships floating here; And now the number of these ships is still increasing! Here, this is the position of the spectator representative. Some of them are from the imperial kingdom, some are from representatives of the merchant group, and it is not even ruled out that there are star thieves mixed in.

In this war, the spectators still strictly followed the default rules, and the largest ship was only 100 kilometers, and it was an ordinary ship.

However, the distance of 500 billion kilometers 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 near the Four Great Empires, the distance between galaxies is about two trillion kilometers, and the distance between galaxies in the periphery of the Pearl Star Field (near the South Gate Galaxy) is not more than five trillion kilometers; the gravitational influence range of galaxies can reach the maximum range of four or five light years, but the core influence generally does not exceed 300 billion kilometers.

It can be seen that the distance of 500 billion kilometers in the galaxy is like being at the doorstep, so it is not absolutely safe. But the Spectator Group itself is an adventurous industry, and it can't be too far! Detectors flashing with photoelectric information are scattered around, and then slowly fly forward. This is an instrument used to capture information about space battles, and in order to avoid misunderstanding, it has to be specially labeled. Of course, when fighting, no one will pay attention, and if it is destroyed, it will fall; Everyone can only say, try to say: we are making soy sauce; The viewing group must have the consciousness of the viewing group.

And this time. The fleet of the Tianyun Empire has already traveled more than half of the distance, and it is still a light year away from the human beings on the earth. However, along the way, the princes and generals of the Tianyun Empire, and even the soldiers, are all extremely distressed, and everyone knows the tactics of the human beings on the earth, but they are really powerless! I've tried a lot of things, but it still doesn't work!

"Your Highness, as of now, you have wiped out 300 warships of a hundred kilometers of the human race on Earth. 2,000 small warships; But the attack of the other side. It still did not stop, but as we became familiar with our attack methods, etc., the losses became less and less, and the harassment of us became more and more severe! The adjutant looked emaciated. This is a lot of trouble in recent times!

"So much wiped out. Still not retreating? "The eldest prince is also a little emaciated. During this period of time, all the soldiers of the Tianyun Empire did not have much rest; Every now and then, you'll be woken up by an alarm. Then he woke up reflexively and immediately sat down at his post.

To be honest, although he was on a hostile position, the eldest prince admired the courage of these earth warriors; In space, these earth humans have no backup or anything like that, and they also have to maneuver to fight, so once the spaceship is destroyed, then they can only face death! And the most important thing is that not a single captive of an earthling has been captured so far. An important reason for this is that without the protection of the spaceship, intelligent life is too small in the universe, and it can only live a dozen breaths! Moreover, these earth humans have a strong will to die, and some will even take out the pistol on their waist to commit suicide.

Suddenly, the deputy thought of a possibility, "Your Highness, the human beings on this earth have been constantly harassing, in addition to harassing, are they also probing our fighting methods?" ”

Well? The eldest prince was shocked!

And then with the imagination, the more and more sure the deputy found this problem! Yes, according to the current situation, this earth human beings are really cunning and cunning, and every time they do something, they must have several goals! And now, to be able to persist without flinching despite such a severe loss, perhaps there is something more important than courage!

And this task, ninety percent of the time is likely to be constantly testing the attack methods, attack methods, defense methods, reaction speed, and so on of the Tianyun Empire.

The more he thought about it, the more gloomy the eldest prince's face became, because this idea and speculation were too reasonable! There is no room for any suspicion that is reasonable! In war, the reaction speed of warships is an absolute military secret!

"Humph!" The eldest prince snorted angrily, it was too late to say anything at this time, more than a month of continuous harassment had already hollowed out the possible means of the Tianyun Empire.

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

At the same time, on the earth's side, scientists are busy in the bright scientific rooms.

"All the shells of the rail guns are replaced with auto-destructive shells! All Quantum Bubble Bombs are set up with an auto-destruct program. "Zhang Wanfei is inspecting the general control center of the Starry Sky Cannon.

"Your Majesty, it's already set. The shells of all rail guns have an effective attack distance of one light year, and beyond one light year, the gunpowder inside will explode and become debris.

And the same goes for quantum bubble bombs.

As long as they do not hit the target, all shells will automatically destroy at a distance of one light year. "The old scientists are full of confidence.

Zhang Wanfei nodded, a hint of helplessness flashed in his eyes. The reason is very simple, because the rail cannon is a moving physical 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. In such a situation, if there is no limit, it is very likely that after many years, these shells will run into the territory of the four great empires under the influence of black holes!

You must know that the location of the South Gate Galaxy is on the periphery, while the Tianyun Empire is in the inner periphery; Therefore, the direction of attack of the human beings on the earth is towards the interior of the Pearl Star Domain!

"Your Majesty, the message sent from the front has been able to roughly determine the position of the other party, and the strategy of early attack can be implemented!" A ray of light shot out of Zhang Wanfei's hand, and finally condensed into a figure.

"What about losses at the front?"

"Within the plan. The soldiers still refused to return. ”

"Hmm. The rise and fall of the world is the responsibility of the husband. Let them fight with confidence. Zhang Wanfei sighed, and he also understood and admired the mentality of the front-line 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 were very excited! Perhaps, for them, this is just a special scientific reality. However, this experiment will face more than fifty million elite troops of the Heavenly Cloud Empire.

The Tianyun Empire didn't know that just a light year away, the human beings on Earth were already preparing to strike in advance.

This can't be blamed on the Tianyun Empire being careless, there's a reason for that. The full sphere of influence of a galaxy. It is quite possible to reach the sphere of influence of two or three light-years or even farther 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, with gravitational fields of different sizes and strengths acting in space, superimposed on each other, and the influence of black holes. Plus the universe itself is in constant motion. In the end, the guide is zhì. The space fluctuations in the Pearl Star Field are very large, and there is a slight gap in time, which makes it almost impossible to lock at an ultra-long distance. Because. Maybe the position you calculated one moment will change the next!

At a distance of one light year, even light would take a year; At such a long distance, it is too normal to deviate by a second or two, and the deviation can be an hour. And one second is a deviation of 380,000 kilometers!

Of course, there are no absolutes, and if you use a covering attack, there is still a certain danger. Therefore, the fleet of the Tianyun Empire is also very careful.

But the Tianyun Empire never thought that the small special forces on the earth, in addition to harassing, detecting the means of attack, etc., would locate the location of the Tianyun Empire's fleet for a month, and also analyze the laws of their fleet movement for a month.

All these actions make it possible to lock attacks at a long distance with more precision!

The error may still be large, but it is no longer a headless fly.

In fact, there is another thing that makes the Tianyun Empire careless: in the past, the wars in the Pearl Star Domain were mainly energy cannons, but the energy cannons would automatically dissipate in space; Rather than being like a rail gun, which can theoretically move without limits. Such a mindset, in a certain way, restricts their consideration in a certain aspect.

In the South Gate Galaxy, 3,000 rail cannons began to be charged, and in an instant, blue, white, red, and purple lightning and brilliance were like coiling dragons, winding on the rail cannons that were tens of thousands of kilometers long; The rails seem to be incarnated into the most brilliant treasures in the world.

Well, perhaps for the human beings of the earth, this is indeed a treasure, a treasure related to the fate of the nation.

The distant viewing group received the information as soon as possible, and everyone's eyes widened, even the viewing groups of the four empires! Everyone has the rail cannon technology, but everyone and country or race wants to see how the human beings on the earth use the rail gun! In fact, the rail cannon itself, which is tens of thousands of kilometers long, has already made the eyes of all the empires light up! Just because you know the principle doesn't mean you can master it!

In a technological society, there is no useless technology, only useless technology in the right place! There is only technology that has not been developed to the extreme. Obviously, the rail cannon is one of the pinnacles of electromagnetic technology; And the rail gun with a length of tens of thousands of kilometers is the pinnacle of the rail gun technology series!

It took two days to recharge...... The human beings of the earth will not sue you, we are hiding! Since time is not very tight, the humans of the earth are also willing to hide their means!

Hiding a little gives you an advantage; If, in a more intense battle, the rail cannon suddenly completes its charge within a few hours, it may seriously disrupt the enemy's war deployment.

It was not until 50 hours later that the charging ended, and the rail cannon finally underwent a qualitative change, a lightning bolt was like a thin silk thread, hovering finely on the surface of the rail gun, so that the rail cannon that was tens of thousands of kilometers long seemed to turn into a crystal clear crystal pillar at this moment, giving people a feeling of crystal clear and warm like mutton fat jade. It's just that this crystal pillar is not only beautiful!

At a certain moment, the engine behind the rail cannon starts, and the hazy water vapor sprays out, and the rail gun slowly advances, and when it has a certain initial velocity, the rail gun finally starts!

But I saw that the shining pillars of light flew out for millions of kilometers before dissipating; But in the process of this ejection, one by one, large and small rail-rail cannon shells have disappeared in space with a roar.

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

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

Accelerating a stationary cannonball to 0.7 to 0.8 times the speed of light is not a simple matter, and the long charge and huge reaction force, as well as the inflexibility of the Star Cannon itself and the week-long readjustment time, are all disadvantages.

Such a situation made many military staff officers in the battle group breathe a sigh of relief, but also some helplessness.

Obviously, the rail cannon is stronger, but it is very inflexible. This kind of starry sky cannon defense seems to be a little insufficient, let alone used for offense. This is also a reason for the relief.

But I have to say that such a huge cannon is really terrifying. Starting from zero and accelerating an object directly to the speed of a few tenths of a light is a technology that makes a difference. For example, the staff officers of the four empires thought that the huge space continent could completely adopt such a starry sky cannon as one of the main artillery technologies!
