In the year 2750, in the starry sky of Orion's cantilever hub, an unmanned fleet appeared after a long journey.

Nana, who was always paying attention, naturally learned of the situation and began to take stock of the current situation of her fleet, "The loss of 15% took 95 years in the end, and it was really slow, but fortunately, 3 jump passages connecting the central region of the ghost star cluster are under construction, and this time will soon be compressed to 60 years." ”

Nana looked around, the central area was as beautiful as when it was first discovered, if there was any flaw, it was that the starry sky was a little dim, it was caused by the white dwarfs left behind after a large number of stars were extinguished, neutron stars, and the brilliance between the stars was clustered into clusters, that was because a large number of space-time bubbles were distributed nearby, distorting the evenly distributed starlight.

"Theoretically, although our goal is to come and investigate the unknown, and by the way, to find the deep diving mother, I don't know when this work will be completed, so let's just build a base."

It didn't take long for Nana to find a reason, and she quickly found a gaseous planet with a diameter of 210,000 kilometers, surrounded by a satellite with a diameter of 8,000 kilometers.

"It's really rich, and I just found a planet to explore casually." Nana asked the main force of the unmanned fleet to turn around, and then selected the wolf-class ships in the fleet to head towards the rest of the central area in batches, the goal of which was naturally to explore the area.

Cao Chuan also got the news that the unmanned fleet had arrived at the target, and he did not hesitate to put down the work at hand, and found that compared with the unmanned spacecraft sent by the original pioneers, this fleet of 10 million unmanned legions can be described as fully armed, so he can immediately put into work without any rest when he arrives in the central area.

Cao Chuan saw that Nana was already developing at this moment, and he saw that the wolf-class spaceship was constantly moving into the distance, and almost every week of advancement, it was able to open a map of a new star system.

At this time, the landing of a large unmanned regiment was completed. The No Man's Fortress was built, intending to follow the steps of what he had done in the Deep Space Path.

The difference is that this time it has entered the fourth generation of unmanned units, and in addition to the basic construction, the unmanned fortress is to receive the relevant drawings and designs of the fourth generation unmanned units. Adjust to the appropriate stage.

The third-generation joint production workshop can be upgraded to the fourth-generation in a fixed way, which is also the advantage of unmanned units after obtaining perfect self-replication, without human involvement.

Even so, Nana and Cao Chuan personally boarded the satellite, named Fulcrum, a few days later, to check the production of the fourth-generation unmanned unit.

"The production of the Dreadnought is going well, due to the shortage of materials in all aspects, the output is only 30% of the expected for the time being, and the corresponding atomic material sources need to be addressed, as well as the establishment of a larger-scale industrial zone."

"Phantom attack aircraft due to technical deficiencies. In the region, the scrap rate of finished products is about 20%, and the production process and process need to be adjusted to ensure quality. ”

Cao Chuan just looked at the data and thought of ways to optimize it, so that the fourth-generation unmanned unit, which had just come out, could enter the mature stage faster.

On the other hand, Nana came in person, rather than sending her doppelganger, naturally because the fortress represented a possible future defense line for humanity, imagine if the Deep Dive Mother intended to do mischief to humanity. It is bound to launch an offensive from the central zone and involve the 10,000 planets bordering here in the flames of war. If you prepare well in advance, you can snipe at the conspiracy of the deep diving mother.

"The hosts... The Central District is a great place. After Nana's larger-scale exploration of the unmanned fleet, the data accumulated at hand had exploded, making her clearly realize what kind of place they had discovered, and her heart was already a little shaken and wanted to expand drastically

"It's a pity. This was once the galactic lair of the Deepdiving Female, where devastating wars took place, and the Deepdiving Females are not dead, perhaps waiting for enemies to covet its legacy. Cao Chuan seemed to know Nana's thoughts, and he had actually discovered Nana's small movements earlier. Deliberately turning a blind eye to it, but that doesn't mean it's completely laissez-faire.

"So, it's okay with a little development." Nana seemed to hear her master's meaning and defended, "Otherwise, what a waste!" ”

"Of course I agree with that, but we have to wait until the deep-diving female shows up, so we can keep an eye on it, and by the way, the birds will occupy the magpie's nest and snatch all the central areas."

"Grab the unknown territory? Sounds like a good idea. Nana agreed with her master's plan, anyway, she had to prepare for a few more decades before she could increase the size of the unmanned army here by a certain order of magnitude, and she held back as if there was nothing to lose.

On the surface of the planet, the unmanned fortress quickly transformed into an unmanned planet, and after the second batch of 20 million unmanned legions, the defense force of the fulcrum star has been quite abundant.

The metal cement shell quickly wraps the planet, and it looks shiny from a distance, giving people a sci-fi fashion feeling. Each building can accommodate at least 1 billion unmanned units and 20 million pioneers, in short, this number will never be reached in 10 years.

The unmanned spacecraft is far away, and the fastest so far is only 60 light-years away, and as a result, the rich planets are still endless, and because the main goal of the unmanned spacecraft is to search for the surviving unknown and deep-diving mothers, there is not much time to stay near the star system.

At this moment, the East Galaxy Company has not officially occupied these planets, and in fact, it has already been included in its own pocket, so it has never had a chance to explore and understand how much wealth they have, which is regrettable, and I am afraid that it will have to wait until the Pioneer arrives to have the opportunity to do this.

"It is expected that around the year 2800, we will reach the edge of the central zone, the final point of the original deep diving mother's disappearance, to make a confirmation."

This is the inference that Cao Chuan saw, those spaceships that were sent out to travel at an average speed of 100 times the speed of light would have to reach their destination at the earliest, and it would be another 50 years at the earliest.

At this time, the first group of pioneers who followed arrived, they were less than 10 light years away from the fulcrum, and they had just finished reporting their location, they were one of the few adventurous fellows among the pioneers, they were not afraid of death, and they yearned for excitement, so the mysterious central area was very suitable for them.

The number of these pioneers is 50,000, all of which are transported through a home-class starship, and as for their weapons and equipment, almost all of them were sold or stored when they came, and because of the freight charge, it is better to wait until the destination to raise their own funds.

However, considering that the Hub is such a rich place, it may not take much time for them to earn enough merit to buy themselves a new batch of weapons and equipment, even trendy gadgets like the fourth-generation mech. (To be continued.) )
