More than three thousand years have passed since human civilization launched a large-scale attack on the Cepheus cantilever.
The Aquarius Arm War ended 693 years ago, and human civilization completely wiped out the silicon branch and the omnic branch entrenched on the Aquarius Arm.
At the same time, the expansion of human civilization in the outer direction of the Orion cantilever has also advanced outward by about 1,229 light-years.
This kind of advancement refers to the expansion of the boundaries of human territory, not the scope of exploration.
In fact, the scope of human exploration at this time extended about 1,800 light-years beyond the territorial boundaries.
In addition, one of the sparks of human civilization has reached beyond the Milky Way.
That's right, this spark of civilization was launched three thousand years ago. It was wrapped in a neutron cage, flew at nearly the speed of light for more than three thousand years, and almost crossed the void of three thousand light years.
When this plan was implemented at that time, it was mainly just in case, leaving an extra escape route for human civilization.
As we all know, there are two dwarf star galaxies surrounding the Milky Way, the Small Magellanic Cloud and the Large Magellanic Cloud, which are also affiliated with the Milky Way.
But in fact, the satellite galaxies of the Milky Way are not limited to the Large Magellanic Cloud and the Small Magellanic Cloud.
For example, there is a small star system in the void about 2896 to 4253 light-years away from the Orion cantilever. This star system has only more than 3,000 stars.
This is one of the many small star systems affiliated with the Milky Way, and it is also the closest small star system to human civilization.
Therefore, this small star system named "Tianxuan Star System" has been targeted by human civilization.
At the same time as this spark of civilization successfully took root in the Tianxuan star system.
…
At this time, the first batch of high-energy neutron shells finally arrived at the Cepheus cantilever after a long journey of more than three thousand years.
The Silicon Clan's base camp has just received the "delayed news" that the expeditionary force successfully landed and began to conquer that star field.
Obviously, these news, which had been delayed for more than three thousand years, did not make the Silicon Clan base camp be more vigilant. They thought that their opponents this time were still the weaklings they had encountered before.
Just when they were receiving reports from the expeditionary force one after another.
The neutron shells fired by the high-energy particle cannon of human civilization also swept across.
A neutron shell containing terrifying energy instantly penetrated an Earth-like planet, leaving a huge gap in the Earth-like planet.
【Enemy attack!】
[Quick transfer...]
Various communication electromagnetic waves are rippling in various planetary systems on the edge of the Cepheus cantilever, but this cannot stop the strikes of neutron shells.
In particular, stars used as reference objects have received special attention from neutron bombs.
A red dwarf star was instantly hit by more than a dozen neutron shells, blasting out plasma jets on the surface, followed by more intense runaway nuclear fusion, and a large number of heavy elements were ejected.
The Silicon tribe and various facilities around the red dwarf star were also severely damaged.
A doomsday scene began to erupt on the edge of the Silicon Clan's stronghold, and then quickly spread to its core area.
Even though the leaders of the Silicon tribe in the peripheral areas tried their best to quickly report the situation to the core area, it was of no use at this time.
Because electromagnetic waves, gravitational waves and neutrino communications cannot break through the speed of light.
This means that even if they notify the Silicon clan behind them, the neutron bombs will arrive at almost the same time.
In particular, the density of neutron shells that have swept across several areas that have attracted human attention is dozens of times higher than other areas.
After human civilization developed the gravitational shield technology, it continued to launch particle cannons to hit the Andromeda cantilever.
After all, when it can defend itself against the enemy's attacks, human civilization takes the strategic initiative, so it seems a little unscrupulous to attack the Silicon Clan's base camp.
Tens of thousands of stars were blown up.
The dazzling flash of nuclear fusion flashes continuously at the edge of the cantilever of the constellation Cepheus.
This ultimate beauty of destruction is painting a scroll of death on the Milky Way.
Even the ruthless Silicon tribe members felt extremely angry when faced with such a tragic loss.
However, the blows of human civilization are almost non-stop heavy rains, which do not give the Silicon tribe any chance to breathe.
This is the cruelty of space war.
The weak may have never even seen the face of their enemy, and have no justice or reason to speak of.
Weakness is the original sin.
If the Silicon race had not been exposed in the first place, they might not have attracted the attention of human civilization.
But there are no ifs in this world.
Since they have provoked human civilization, they must be mentally prepared to fight to the death with humans.
The indiscriminate bombardment of neutron bombs lasted for a full 100 Earth years.
In the cantilever of Andei, more than 17 million stars were exploded, and countless planets were affected.
Especially on the side close to the cantilever of Orion, there is basically no complete planetary system to be found.
The leaders of the Silicon civilization already knew where the enemy came from.
[Retaliation! We must retaliate with all our strength!]
[Order each tribe to start building large particle cannons, and then attack with all their strength...]
【I agree!】
Due to communication limitations, the Silicon Clan does not have a ruling core, but the leaders of each planetary system act independently.
Of course, the Silicon people are all ruthless in character, so the decisions they make are all very similar.
Revenge against human civilization is basically their common choice.
It's just that they don't know yet that human civilization's attack on the Cepheus cantilever is not over yet, or in other words, this is just the beginning.
About two hundred years later, the Silicon tribe, which had recovered at this time, also fired high-energy particles wildly towards the Orion cantilever of human civilization.
However, at this time, according to the previous timetable of human civilization, the defensive circle of the gravity shield has just been completed, and productivity has begun to be gradually transformed into attack power.
The Silicon clan, which had just recovered, was once again hit by dense neutron bombs.
Although they had suffered losses before, these Silicon tribesmen hid some of their members and facilities behind neutron stars and black holes.
However, the number of natural black holes and neutron stars is ultimately limited, and those planetary systems without protection have been hit hard again.
But this time, the neutron bombs of human civilization show almost no signs of stopping.
In the vast void, stars and the wreckage of battleships are intertwined, and plasma and light radiation are sputtered everywhere.
The base camp of the Silicon civilization has long lost the peace and tranquility of the past, leaving only endless wreckage.
However, the Silicon civilization did not give in. After all, their racial characteristics created their ruthless character and made it difficult for them to be completely eliminated.
However, just when they fought back desperately.
More than a dozen ill-intentioned human civilization fires have quietly arrived at the edge of the Cepheus cantilever.
