Homo sapiens.

For the cosmic war between the spanning arms, time is undoubtedly the most difficult.

Thousands of light-years at every turn, before there is no super-light-speed navigation technology, even a near-light-speed weapon is still very weak.

This powerlessness is long on the time scale.

Human civilization is going all out to attack the Andromeda base camp of the silicon civilization, but this kind of attack will take at least 6000 years before there will be obvious feedback.

At this time, the war between the three clans on the arm of the water bottle has entered a fierce stage, and the flames of war have destroyed countless planets.

However, humans are in a clear advantage in this area, almost overwhelming the silicon clan and omnics.

at the same time.

Human civilization is also rapidly expanding towards the outer direction of the Orion’s cantilever, and at present, it is advancing 100 light-years to the outer star field of the Orion’s cantilever every 20 years.

Don't look at this speed is not fast.

In fact, for a first-level civilization, the outward expansion of 100 light-years every 20 years is already very fast.

While rapidly expanding its territory.

Various groups of human civilization have also launched security strategies one after another.

After all, as humans, the silicon race, and the omnics fight in the water bottle arm, it is difficult for other civilizations to hide the fact that there is a powerful first-level civilization in the Orion arm.

The Strategic Analysis Office of the Federal Headquarters is not a fool, and must know that it will be a matter of time before the Orion cantilever is exposed.

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

What happened to the omnic civilization at the beginning sounded the alarm for human beings. There is a quasi-secondary civilization in another star system. Is there a quasi-secondary civilization in the Milky Way?
This is also the reason why human civilization keeps a respectful distance from the galactic center region of the Milky Way.

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

Why is the civilization in the galactic center region so powerful?
The answer is that the density of stars in the galactic center region is very high, making it difficult for planets in the galactic center region to exist stably. This environment is very extreme.

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

Human civilization does not want to gamble that there is no strong civilization in the galactic center, because if the gamble is wrong, the consequences will be disastrous.

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

The first is to improve the local security defense system.

The second one is to make every effort to eliminate the control area of ​​the omnic civilization and the silicon civilization in the arm of the water bottle.

The third one is to develop as far as possible to the outer reaches of the Milky Way.

Human civilization is a civilization that lacks a sense of security, or in other words, most of the first-level civilizations are insecure and suffer from severe delusions of persecution.

This is actually caused by the environment.

The positioning of the first level civilization itself is too embarrassing.

Zero-level civilization can lie flat, and the ignorant are fearless. Most of their senses about the universe are curious, and that kind of self-loneliness.

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

At the same time, the first-level civilization has no way to get in touch with the second-level civilization. I always feel that the way forward is foggy about how to develop to the second-level civilization.

It is precisely because of this special environment that all first-level civilizations are more or less neurotic.

Why does human civilization seem to go crazy after being invaded by the silicon civilization?
The reason is that in this general environment, human beings have no other choice.

If you don't act first, you are stronger. Once the enemy makes the first move, it will be irresponsible to all new human beings.

At this time, human civilization has fully entered a state of wartime.

Both the neutron star and the black hole inside the human domain are being used.

In fact, there are not a few neutron stars and black holes in the Milky Way.

Among them, the number of neutron stars is about 37.69 billion, while the number of black holes is about 4536 million.

Compared with the 3928 billion stars in the Milky Way, the proportion is not too high, and a large part of neutron stars and black holes are concentrated in the center of the galaxy.

At present, there are about 23 neutron stars and 8553 black holes in the human territory.

The territory of human beings at this time is 2667 light-years widest and 891 light-years narrowest, with a total of more than 2000 million stars inside.

This is the true strength of human civilization.

To use neutron stars and black holes as natural shelters, you must not be casual, because these two celestial bodies are inherently dangerous.

For example, pulsars among neutron stars must be careful of the pulse stream ejected by them, and a certain distance must be kept.

Otherwise, once it is swept by the neutron star's pulse flow at close range, it will be very dangerous even with a magnetic field deflection shield.

Not to mention black holes.

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

When building neutron star shelters and black hole shelters, human civilization has tried every means to calculate the safest position interval.

All this requires careful calculation.

After all, the enemy of human civilization is not only the silicon civilization, but also the one-eyed civilization staring at the centaur cantilever, and the mysterious and unpredictable galactic center area.

The layout of various early warning systems also covers the entire human territory in all directions, ensuring that no attack can take advantage of loopholes.

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

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

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

Under the delay of hundreds of thousands of light years, the party with super-light speed communication technology really has the advantage.

Now human civilization builds bunkers around neutron stars and black holes, the purpose is to enhance its own defense.

Further enhance the comprehensive strength of human beings.

Of course, OSA did not commit all its resources to the bunker program.

Because the positions of natural neutron stars and black holes are fixed, there is absolutely no way for human civilization to move neutron stars and black holes at this stage.

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

All eggs must not be put in the same basket.

As a supplement, the Dark Star Project has also become another choice for various groups.

After all, neutron stars and black holes need hundreds of groups to share one, which is too crowded.

So many groups put resources into the artificial earth.

Of course, in addition to the Dark Star Project, there is another plan that is also very popular, and that is the "Lights Off Project".

This plan is actually a variant of the Dyson sphere, selecting some small-mass red dwarfs or white dwarfs as targets for transformation, and then wrapping these small stars.

All in all, in order to hide oneself in human civilization, it is almost like the Eight Immortals crossing the sea - each showing their own magical powers.

Just as human civilization was working hard, another piece of good news came from the Science Division.
