Eleven years ago, Yan Xia received the coordinates of the Silken Civilization from the ten fleets.
As he was unaware of the situation there, he analyzed that these coordinates might be a way for the fleets to locate themselves and use super-distance weapons to break through the siege.
However, there was no time indicated, which was a problem.
Yan Xia wanted to contact them, but they never responded.
Why?
At this time, all ten fleets had already lost their stellar energy stations, and their energy was extremely precious.
To inquire again at this point and have the fleets consume energy to reply would be to deplete their lifelines.
The coordinates alone should be the reason why the fleets didn't want to waste energy.
Yan Xia judged that time was not actually important because his order was for the fleets to gather at that location. Once gathered, the fleets would surely be besieged, so their coordinates and those of the Silken Civilization fleets would not change much.
Even if the Silken Civilization wanted to change, the Federation fleets would not move.
This was just his speculation, which turned out to be a big mistake.
The reason there was no time indicated was that the Federation was the one proposing to launch the weapon, and Yan Xia was the one confirming the location. So the fleets thought that Yan Xia had already launched the weapon when he was conveying the information.
It was all a misunderstanding.
The fleets had been waiting for a response, eagerly anticipating it, but never realized that it was a deception.
...
After obtaining the coordinates, Yan Xia urgently ordered the deployment of a new type of weapon.
This weapon was extremely powerful and complex, and the estimated preparation time was originally one year, but because it was the first time this weapon was activated, many problems arose, and the time was extended to the fourth year.
This was a major blunder.
On the Kunlun, Yan Xia kept receiving various reports, making his face turn dark.
But there was no other way; the failure rate of high-tech equipment is inherently high.
At this point, other weapons should have been activated immediately, but each activation of the super-distance weapon required the energy of one or even several stars. It's understandable that replacing the weapon would require half a year to a year of preparation, which was a waste of time.
However, the new weapon malfunctioned not just once, but a second time, a third time...
Time was dragged on like this.
For Yan Xia, this was extremely absurd.
Fortunately, in the fourth year, after a total of eleven attempts, the new weapon was finally activated and fired towards the coordinates.
The projectile approached the speed of light and even showed signs of reaching it.
It was not a physical entity but energy.
Not positive energy, but negative energy.
Starting from the Wind Civilization, the Federation had been researching negative energy weapons.
However, the development of negative energy was extremely challenging, which also made the progress of weapon research very slow.
It wasn't until 1700 years ago that the negative energy super-distance weapon was truly born, and the Federation began installing it on the border to deal with the Silken Civilization.
It can be said that the entire Federation currently has only one such negative energy weapon, so it's understandable that its malfunction is also a problem.
But why was it still activated?
Because it was powerful!
It had a wide coverage area.
It was not easily defended against.
Its advantages overshadowed its disadvantages.
In the 21st century, negative energy was considered the energy with the least possibility of achieving superluminal motion, but this assumption has been denied in the present.
Negative energy cannot make objects move faster than light; spacetime is far more stable than imagined.
To achieve warp speed, the required energy is beyond what negative energy can provide.
But negative energy is indeed a form of gravity.
So, negative energy weapons are also gravity weapons.
However, after being launched, they do not form visible gravitational waves. If you make a model, you can see that this weapon is like an iron ball rolling on a mattress, causing it to bend.
Such bending usually only occurs in massive celestial bodies and black holes.
Negative energy can achieve the same effect.
The reason why negative energy weapons do not disperse over super-long distances is also due to gravity.
The spacetime depression formed by gravity causes the negative energy to continually contract towards the center as it advances, rather than dispersing outwards.
Although entropy increase and decrease exist, they are negligible compared to the vast energy of the weapon.
The battlefield, where the fleets gathered, was 10 light-years from the Federation border, but the distance from the negative energy weapon was 12 light-years.
So, when the negative energy weapon arrived, it was actually the 16th year, and the ten fleets discovered the details of the Silken Civilization another five years later.
In these five years, they encountered even more fierce attacks.
They lost another two giant ships, nearly ten thousand biological warships, and a super-star worm nest, a heavy loss.
However, the Silken Civilization's fleet did not suffer large-scale losses, and the Federation's statistics showed that only around 2,000 warships were destroyed.
The unbalanced casualty ratio not only widened the power gap between the two sides but also affected the mindset of the Federation's soldiers.
The Federation's soldiers rarely encouraged each other, let alone engage in basic communication.
These were the darkest five years.
The morale of the Federation's soldiers, which had been high due to their fearlessness, collapsed and fell into the abyss.
The only thing they firmly held onto was the coordinates they had at that time.
Yan Xia thought of them, and they also thought of it, and a glimmer of hope remained in their hearts.
As for using the fast-child communication equipment to contact them, it would only be a waste of energy.
If the commander had known the significance of the coordinates, the weapon should have been launched earlier, and there would have been no need to wait until the 11th year to launch it. Contacting them in the 11th year would have been meaningless.
If the commander didn't know the significance of the coordinates, there would have been no way to contact them, and after waiting for so long, they could only rely on themselves now and couldn't wait for another 11 years for the weapon to be launched.
This hope was so slim.
If they put themselves in the commander's position, they should have launched the weapon upon receiving the coordinates, and the latest arrival time of the weapon should not have exceeded 12 years.
After 12 years, it also meant that the commander did not choose to launch the weapon at the first opportunity, or even choose to contact them at the first opportunity, which also meant that they might have been abandoned.
Abandoned!
This was also one of the main reasons for the decline in the morale of the Federation's soldiers.
The Federation had already abandoned them, so who were they striving for at this point?
Themselves?
But it was impossible for them to win on their own.
So... let it go!
However, in the 16th year of despair, the remaining eight giant ships observed that the Silken Civilization's warships were being attracted by a mysterious force towards a center of mass.
It was not a black hole.
It was a massive celestial body that could cause spacetime distortion.
At the same time, it was different from ordinary gravity.
Because its range of influence was too wide, and the gravity was spread out too evenly.
The surface gravity of a celestial body is definitely incomparable to its core gravity, but the gravity at the edge of this gravity source was the same as that at the core.
This meant that even at the edge, objects attracted by it would have difficulty escaping the gravity.
The tens of thousands of Silken Civilization's warships were directly torn apart by this gravity.
At this moment, the Federation's soldiers stood in place, watching this scene, and hope rekindled in their hearts.
The Federation had not abandoned them!
