After the war turned against them, both the [Membrane] and other members of the Pastoral Faction focused all their attention on the Cleaners civilization.

On the other hand, no one in the entire pastoral faction expected that human civilization could advance to the eighth level of civilization, master wormhole technology, and even build a starship of the eighth level of civilization in just a few hundred years!

then……

By sheer coincidence, human civilization slipped smoothly out of the Virgo Cluster right under the noses of the Cleaners and the Pastoralists.

...

Earth's calendar years.

With the maturation of wormhole technology, the speed of human civilization has been improved like never before.

It took only five hundred years for the human fleet to successfully reach the Shapley Supercluster.

(The Shapley Supercluster is about 600 million light-years from Earth.)

This is the fleet's primary objective.

The second goal is to use the galaxies within the Shapley Supercluster to gradually travel towards the Boötes Void further ahead.

While the vacuum zero-point energy engine can directly extract energy, galactic matter is still essential to ensure efficient ultra-long-distance travel.

According to the plan, the human fleet will take a "shortcut" by directly traversing the entire Shapley Supercluster and entering the Tenth Empire's latest destination—the Boötes Void—from another direction!

Then, they rendezvous in the hollow region of Boötes.

This was also a proposal from the Sekor civilization.

Even modern human civilization faces considerable danger in the face of attacks from the pastoral faction.

If we were to act together with the Tenth Empire...

Of course, they are no match for the pastoral school.

But at least it can reduce the risk a little.

To ensure the safety of the "new big brother," the Sekor civilization even launched another ultra-high-power wide-area tachyon broadcast to solicit opinions from the [Tenth Empire].

As fellow countrymen from the Milky Way, the Tenth Empire, amidst surprise and delight, readily agreed to the request.

P.S.: As you can probably tell, this book is nearing its end.

It'll probably be the finale within a month.

The ending is hard to write, but I'll try my best to update twice a day...
