Time is undoubtedly the most difficult for a cosmic war that spans the cantilevers.

Thousands of light-years at every turn, before there is no faster-than-light travel technology, even near-light speed weapons still seem very powerless.

This powerlessness is a long time scale.

Human civilization is fully attacking the Silicon civilization's Xianying base camp, but this blow will not appear to be obvious until at least 6,000 years later.

At this time, the war of the three clans on the arm of the Aquarius has entered a white-hot stage, and the war has destroyed countless planets.

However, human beings are in a clear dominant position in this area, almost pressing the silicon family and intelligent machines.

Meanwhile.

Human civilization has also rapidly expanded to the outer side of the Orion cantilever and is currently advancing 20 light-years to the outer star field of the Orion cantilever every hundred years.

Don't look at this speed is not fast.

In fact, for a first-level civilization, the range of 20 light years that expands outward every hundred years is already very fast.

While rapidly expanding its territory.

The various groups of human civilization have also started their security strategies one after another.

After all, with humans, the Silicon Race, and the Wisdom Machines fighting in the Aquarius Arm, it is already a fact that other civilizations have discovered the existence of a powerful first-level civilization in the Orion Cantilever.

The Office of Strategic Analysis of the Federal Headquarters, again, is not a fool and surely knows that it is a matter of time before the Orion cantilever is exposed.

Although there is a high probability that second-level civilizations will not participate in the fight between first-level civilizations, this does not mean that human civilization can sit back and relax.

The encounter with the intelligent civilization at the beginning sounded the alarm for mankind, there is a quasi-second-level civilization in another star system, is there also a quasi-second-level civilization in the galaxy?

This is also the reason why human civilization has stayed away from the galactic heart region of the galaxy.

As the most resource-rich region in the galaxy, if there is a civilization there, it must be very powerful.

Why is the civilization in the Silver Heart region so powerful?

The answer lies in the very high density of stars in the galactic region, which makes it difficult for the planets in the galactic region to exist stably, and this environment is very extreme.

And the more extreme the environment, the more terrifying the creatures are born.

Human civilization does not want to bet that there is no strong civilization in the Silver Heart region, because once this bet is wrong, the consequences are unimaginable.

Therefore, at this stage, there are three main strategic directions for human civilization.

The first is to improve the local security defense system.

Second, make every effort to clear the control area of the intelligent machine civilization and the silicon civilization in the Aquarius arm.

The third is to go as far as possible to the outer reaches of the galaxy.

Human civilization is a civilization that lacks security, or in other words, the vast majority of first-level civilizations are insecure and have serious paranoia of persecution.

This is also caused by the environment.

The positioning of the first-class civilization itself is too awkward.

Level 0 civilizations can lie flat, and the ignorant are fearless, and most of their senses of the universe are curiosity, and that kind of self-loneliness.

The first-level civilization has realized the cruelty of the universe, and there are a large number of civilizations of the same level around it, and if they do not develop with all their strength, they may be wiped out by other civilizations of the same level.

At the same time, the first-level civilization has no way to come into contact with the second-level civilization, and it always feels that the road ahead is foggy as to how to develop to the second-level civilization.

It is precisely because of this special environment that all levels of civilization are more or less neurotic.

Why did human civilization seem to go crazy after being invaded by the silicon civilization?

The reason is that in this environment, human beings have no other choice.

If you don't strike first, once you are attacked by the enemy, it will be irresponsible to all the new humans.

At this time, human civilization has entered a state of wartime in an all-round way.

Neutron stars and black holes within the human realm are exploited.

In fact, there are many neutron stars and black holes in the Milky Way.

Among them, the number of neutron stars is about 3.769 billion, and the number of black holes is about 45.36 million.

This is not too high compared to the 392.8 billion stars in the Milky Way, and a large part of the neutron stars and black holes are concentrated in the galactic core region.

At present, there are about 230,000 neutron stars and 8,553 black holes in the human domain.

At this time, the widest range of human beings is 2,667 light years and the narrowest is 891 light years, with a total of more than 20 million stars inside.

This is the true strength of human civilization.

The use of neutron stars and black holes as natural shelters must not be done casually, because these two objects are inherently dangerous.

For example, a pulsar in a neutron star must be careful with the pulse stream ejected by it, and a certain distance must be maintained.

Otherwise, once it is swept by the pulse stream of the neutron star at close range, it is very dangerous even if there is a magnetic field offset shield.

And black holes are even more not.

That terrible gravitational field can not only distort light, but also tear stars apart.

When building neutron star bunkers and black hole bunkers, human civilization has tried to calculate the safest location intervals.

All this is something that needs to be carefully calculated.

After all, the enemies of human civilization are not only the Silicon civilization, but also the one-eyed civilization that is cantilevered in the constellation Centauri, and the mysterious Silver Heart region.

The arrangement of various early warning systems also covers the entire human territory in an all-round way to ensure that no blow can take advantage of loopholes.

In fact, as long as the enemy's strength does not exceed the boundaries of first-level civilization, human civilization will basically not be beaten.

This is not the arrogance of human civilization, but the synchronous communication technology brought by the magnetic monopole crystal, which has endowed human civilization with super detection and monitoring capabilities.

And the core attack method of a first-level civilization, the speed of light is its upper limit.

With a delay of hundreds of thousands of light-years, the side with faster-than-light communication technology does have the advantage.

Human civilization is now building bunkers around neutron stars and black holes in order to strengthen its own defenses.

Further enhance the comprehensive strength of mankind.

Of course, the Office of Strategic Analysis did not bet all its resources on the bunker plan.

Because the position of natural neutron stars and black holes is fixed, human civilization definitely has no way to move neutron stars and black holes at this stage.

This poses another risk, which is that once the bunker is discovered, it can be easily targeted by the enemy.

Eggs certainly can't be put in the same basket.

And as a supplement, the Dark Star Project has also become another option for various groups.

After all, neutron stars and black holes need to be shared by hundreds of groups, which is too crowded.

As a result, many groups are investing their resources in artificial earth.

Of course, in addition to the Dark Star program, there is another program that is also popular, and that is the "Lights Out Program".

The plan is actually a variant of the Dyson sphere, selecting some small red or white dwarfs as the target of modification, and then wrapping these small stars.

All in all, in order to hide itself, human civilization is almost eight immortals across the sea - each showing its own magical powers.

Just when human civilization was working hard, there was another good news from the Science Division.
