I don't know how many years have passed, Charloto's swarm has swept through more than a dozen river systems and then set its sights on the former galaxy again.

At this time, they have been away from the galaxy for too long, and they don't know if a new civilization has been born in the galaxy. In order to prevent a new civilization in the galaxy from growing, the swarm embarks on a journey back.

At this time, the civilizations in the galaxy were not aware of the approaching danger, and they were immersed in the excavation and study of the ruins of ancient civilizations.

After such a long period of development, these civilizations have thoroughly mastered the technology left over from the previous generation of civilizations, and have developed new technologies on the basis of these technologies.

Civilizations throughout the galaxy have learned from each other, and all civilizations have stepped up to a higher level.

An epoch-making megastructure that will cost thousands of materials in a galaxy is on the agenda, and it's a mega building in the habitable zone! A world around the stars!

By the time the construction of the Ring World began, the swarm had already left the nearest river system to the Milky Way and began to fly towards the Milky Way in the void.

But at this time, the civilizations in the galaxy did not know about the Zerg! After such a long time, the information about the Zerg left over from the previous generation of civilization has long disappeared in the long river of time. They had no way of knowing how terrible the Zerg were.

When the Rim was built, the biters re-logged into the galaxy!

But this swarm that had just landed in the galaxy did not attract the attention of these civilizations.

And the swarm did not disturb these civilizations at first, but hibernate and carefully recovered, waiting for the best opportunity.

Finally, hundreds of years later, the Zerg, who had recovered from flying across the river system, launched a surprise attack on the nearest civilization.

This civilization was powerless in the face of a fleet of swarms hundreds or thousands of times higher than its own, and was defeated by the swarm in just a few days.

However, at this time, the surface consciousness of the mother queen of the swarm, that is, Charolo, has learned to hide, and she is not in a hurry to devour the creatures of this civilization, but directly takes over the management of this civilization.

Seeing this, the various civilizations in the outside world only thought that there was a civil war in this civilization, but since the other side did not launch a massacre against the indigenous people of the civilization, they did not care too much.

Then the Zerg Mother Empress began to control the fleet of this civilization and launched a sneak attack on the surrounding civilizations, and the Zerg fleet was secretly involved in all the major battles.

As long as there is a battle in which the swarm participates, not a single warship can escape, and even the signal is not received by these civilizations, and everything on the battlefield seems to have become a secret.

In this case, the civilization easily conquered the surrounding civilizations.

Many civilizations in the galaxy regard this kind of war as a normal war between civilizations in the galaxy, and they are just wary of it, but they don't care too much, after all, the galaxy is so big, and the other party is so far away from them!

However, what they didn't expect was that this Zerg would defeat the civilization of half of the galaxy in just a few decades.

After gaining so much territory, the Zerg no longer needed to hide it, and the Zerg Mother directly ordered the Zerg to devour the creatures of these civilizations under her control. The number of swarms doubled overnight!

At this time, the many remaining civilizations in the galaxy finally felt the threat from the Zerg!

The remaining civilizations were forced to band together to form an anti-Zerg alliance to fight the increasingly powerful Zerg. And the headquarters of this alliance is located in the newly built ring world!

They began to concentrate the power of most of the galaxy against the invading swarms.

But it was too late, and the number of swarms was no longer something they could resist. What's more, the Zerg Mother Queen also has a new book with super rules!

(Speaking of the new super-rule book, I have to talk about a period of events after Charloto's swarm flew out of the galaxy, in the countless years of flying out of the galaxy, the mother queen of the swarm, that is, Charloto's surface consciousness, has encountered a swarm several times stronger than her in other river systems, in order to avoid the fate of her own population being devoured, and in order to protect Charloto's body from harm, she chose to submit to this powerful swarm.) But because she joined later, she was disgusted and ostracized from this Zerg line, and Charolo's surface consciousness also had her pride as the mother queen of the Zerg, she rebelled against the Zerg in a fit of rage, and stole a new super-rule book from the Zerg lineage. ）

The superficial consciousness of Charolo, the mother queen of the swarm, directly activated the new book of super-rules, limiting the speed of all ranged weapons in this river system to an extremely low standard.

Overnight, the anti-zerg alliance across the galaxy lost their greatest advantage: range!

While putting all the fleets on the front line, the Anti-Zerg Alliance is stepping up research on new weapons.

Finally, thousands of light years after the Zerg had advanced the battle line, a spherical weapon capable of burrowing into the Zerg warship and causing destruction was developed.

This weapon can heat itself to generate ultra-high heat and use kinetic energy to crash into the opponent's body, causing damage in the opponent's body before returning to the battleship to recharge.

As soon as this weapon was manufactured, it was installed throughout the Alliance, and the warships of the Alliance were equipped with the latest weapon.

The situation on the battlefield was finally alleviated after the appearance of this weapon, and the Zerg offensive slowed down, and the fleet of the Anti-Zerg Alliance used this weapon to slightly alleviate the disadvantage.

But it's a pity that the construction speed of ordinary civilizations can't compare to the hatching speed of the Zerg Battleship Bug after all.

When the Anti-Zerg Alliance builds a destroyer, the Zerg side can cultivate twenty battleship insects as long as the nutrient solution is sufficient.

Although the combat effectiveness of the anti-Zerg alliance warships is much higher than that of the battleships of the same level of the Zerg, even then they can be at most one against five.

And the construction ratio of the Zerg is one to twenty! Even if the Anti-Zerg Alliance can fight five, the other party still has fifteen troops to surround you.

The advantages of the Anti-Zerg Alliance relying on weapons began to gradually decline, and even if the Anti-Human Alliance built warships at full capacity, it could not keep up with the speed of warship consumption!

And with the loss of territory, the Anti-Zerg Alliance gradually began to lose the supply of materials for the manufacture of warships and the shipyard for the production of warships!

On the other hand, the swarm is getting stronger and stronger, and the speed at which they advance is getting faster and faster!

After fighting like this for more than twenty years, the Anti-Zerg Alliance has been forced into a corner of the galaxy by the swarm.

At this time, the remaining territory of the Anti-Zerg Alliance has begun to be insufficient to maintain the consumption of this war, and the people within the alliance have begun to live in poverty.

At this time, the new super-rule book used by the Zerg suddenly expired, and the speed limit on ranged weapons was suddenly lifted!

If this happened earlier, the Anti-Zerg Alliance might have been pleasantly surprised, but now they are left with deep helplessness!

Because they've spent all their resources on building short-range weapons!

They don't have much left of their resources! It's not enough to equip the entire army with new ranged weapons!

In desperation, they had no choice but to start re-equipping the newly built ships with long-range weapons, while the original ships could only use the original short-range weapons!
