The main purpose of the probes was to scan the megastructures within the Claw Civilization Alliance.

For example, the Federation's super-range weapon.

They are generally megastructures.

For example, the Federation's Machine God is also a megastructure.

Most Level 2 Civilizations cannot escape the constraints of physical size.

The advantage of size occupies too large a proportion.

A device with a diameter of 1 meter is simply not as strong as a device with a diameter of 2 meters.

A weapon with a caliber of 1 meter is simply not as strong as a weapon with a caliber of 2 meters.

Unless there is a very high generation gap between these two weapons.

Correspondingly, to create powerful weapons that can resist external enemies, they must be enormous, larger than dwarf planets, larger than planets, and even larger than Stars.

These things are difficult to hide.

Once these are locked on, they can be directly destroyed.

The Flying Civilization deployed within civilization's home universe in the early stages of the war, essentially leaving no room for the Federation to use super-range weapons, and being a smaller Civilization, they also did not fear super-range weapons, which primarily rely on pure particle attacks.

Although super-range weapons also include unconventional weapons.

However, the Federation only possessed one Super Force in the Super-microscopic World, which was not widespread and could not cause too much damage to the Flying Civilization.

Therefore, in Human Civilization's war against the Flying Civilization, including Destiny Ring Star, super-range weapons rarely appeared.

But now it's different.

The Federation will directly enter the Claw Star Cluster through a wormhole at the beginning of the invasion.

At such close range, if large weapons can react quickly and start activating in the early stages of the war, they will cause significant casualties to the Federation.

This is somewhat different from Rasti's war against Geluoluo.

Geluoluo is too small after all.

Entering its core, the space for deployment is only a few light-years.

Moreover, that is the core, and there are many things belonging to the Geluoluo Star Nation itself inside, so using super-range weapons could very likely harm the enemy by a thousand while damaging oneself by eight hundred.

The scope of the Claw Star Cluster is much larger.

Although the location of the wormhole is also in the core area of the Claw Star Cluster.

However, there are many Civilizations within the Claw Star Cluster, and they themselves have not developed technology to utilize wormhole gravity as an energy source, so the wormhole area is not the core of the Eight Great Civilizations.

Once the Federation launches a large-scale attack, the Eight Great Civilizations of the Claw Star Cluster will quickly react and carry out large-scale attacks.

Therefore, it is best if super-range weapons, or other large weapons, can be detected and damaged in the initial stages.

These probes are by no means simple probes.

They are equipped with annihilation devices for Negative Energy and positive energy, and also some evasion capabilities.

Although due to their small size, they cannot achieve complete evasion.

After detecting large devices within the Claw Star Cluster Civilization, these probes will approach, attempt to enter their interior, and hide.

When the war begins, they will act to destroy the core, creating favorable conditions for the Federation's war.

The probes flew through some areas without causing any impact.

For such a developed Civilization, there are many kinds of internal machinery.

In the Federation's interstellar space, countless unmanned detection devices exist; if truly calculated, each Stellar System is estimated to have tens of billions or hundreds of billions.

This is just for those currently operating; for those that have been abandoned and become space debris, in tens of thousands of years, an unknown hundreds of trillions have accumulated.

Sending robots or spaceships to clear this debris wastes energy and recovers little value.

After all, the price of many industrial products is actually very low nowadays.

For example, the current probe, if it were not equipped with some of the Federation's most advanced military technologies, and was merely a civilian version with a detection range reduced to within 1000 astronomical units.

Then its price might only be 5 or 6 energy coins.

Better ones would only be a dozen or twenty energy coins.

If it's just the kind of unmanned equipment found within a Star City or planet, 1 energy coin can buy hundreds or thousands of them.

Even with independent detection capabilities and internal positive and Negative Energy annihilation devices, a probe with some evasion energy detection capabilities would cost at most a few hundred energy coins.

For the Claw Star Cluster Civilization, which has a history of hundreds of thousands or even millions of years, these operating devices and floating debris will only be more numerous.

A 10cm small probe is completely inconspicuous.

They traverse Deep Space and arrive at various Stellar Systems.

The Star density here is very high, and the distances between them are relatively short.

400,000 Stars, but with a radius of only 34 light-years, and a volume of 165,000 cubic light-years.

This means there are 2.42 Stars per cubic light-year, a density more than 600 times that of the area around the Solar System.

Such a place is actually very difficult for primitive Civilizations to emerge.

Although the heat from a Star is difficult to affect Stars hundreds or thousands of astronomical units away, even at a distance of five or six astronomical units, the daytime temperature on some planets can drop to minus one hundred degrees Celsius.

Some smaller Stars are even worse.

However, while heat may not reach, radiation can.

In interstellar space with the density of the Claw Star Cluster, the radiation dose received by its planets is at least hundreds or thousands of times that of Earth.

Especially within the Claw Star Cluster, there are many high-density celestial bodies: wormholes, Neutron Stars, and White Dwarf Stars.

Unknown Civilizations can use these to produce energy, but lower Civilizations must endure the possible jets from wormhole explosions and the high-intensity radiation produced by Neutron Stars and White Dwarf Stars.

Direct hits by these high-energy rays would destroy a planet's atmosphere, and the genes of surface organisms would be shattered, making survival impossible.

However, high-density areas are not entirely incapable of giving birth to Civilizations.

The universe is too vast; even precise equipment created by science has flaws, let alone the rough structure of the universe.

However, when placed within the billions of years required for the birth of life.

Such a possibility is too small.

And the probability of developing into a Civilization, or even an Unknown Civilization, is even smaller.

Conversely, external Civilizations have always coveted such Star-dense regions.

And they do not give the Civilizations within these Star clusters time to develop.

The current Eight Great Civilizations of the Claw Star Cluster also have some extensions outside the Claw Star Cluster.

These extended areas are called "Primitive Navigation Routes."

The Eight Great Primitive Navigation Routes are the paths by which the eight Civilizations arrived at the Claw Star Cluster hundreds of thousands or millions of years ago.

In fact, there are far more than just these routes.

Over millions of years, the number of Civilizations that arrived at the Claw Star Cluster exceeded 30, competing and fighting each other, and ultimately only these eight Civilizations remained in balance.

However, who knows what changes these eight Civilizations will undergo in the next hundreds of thousands of years.

If there were no external enemies.

However, this external enemy seems to have already bared its fangs.

Creating a gap among the Eight Great Civilizations.

Although the war between the Eight Great Civilizations and the Devouring Zerg has always existed.

The common people below hate the Devouring Zerg to the core.

Yet, there are some dealings between the high-ranking officials.

The Eight Great Civilizations used some resources to purchase information from the Devouring Zerg.

The Human Civilization, from which the Devouring Zerg originated, has been making frequent moves recently.

The two sides are only 7500 light-years apart.

It seems distant.

But for advanced Civilizations like them, it's just a not-too-far, not-too-close distance.

From an even more macroscopic perspective, they can even be considered neighbors.

The Eight Great Civilizations have always paid attention to the Federation, mostly because of the Devouring Zerg.

After all, the Devouring Zerg is too powerful.

They have always wanted to investigate its origin.

Then they traced it back to Human Civilization.

And then they discovered that this branch of the Devouring Zerg they were fighting was merely one branch of the Devouring Zerg.

The Devouring Zerg is also just one branch of the entire Zerg.

This almost made them despair at the time.

But fortunately.

They ultimately held them back.

Now the Devouring Zerg has turned its attention to a distant target.

A failed Civilization that once vied for control of the Claw Star Cluster.

It is only 2000 light-years away from the Claw Star Cluster.

What concerns the Eight Great Civilizations most now is that the Devouring Zerg told them that the most powerful force within Human Civilization has recently been accumulating military strength, perhaps with intentions of expanding outwards.

According to Zerg intelligence.

The number of Civilizations within 10,000 light-years of Human Civilization is not large.

There are only a mere twenty or thirty Unknown Civilizations.

If many Civilization alliances are counted as a single Civilization, there are actually fewer than ten in total.

If Human Civilization bares its fangs, they will inevitably suffer.

However, fortunately, the distance between them is still relatively far.

If Human Civilization wants to reach them, they still have some buffer time.

This was just the initial thought.

Recently, the Devouring Zerg informed them of new intelligence.

They spent 100 Stellar Systems on the Primitive Navigation Route, along with their energy extraction equipment, to trade with the Devouring Zerg for this intelligence.

That is, Human Civilization will launch wars against other Civilizations through wormholes.

This made the Claw Civilization Alliance, which possesses many wormholes, tremble with fear.
