Li Qingsong still devoted almost all of his energy to technological development.
Numerous large scientific installations, countless large, medium, and small laboratories, billions of clone bodies, and millions of Blueprint scientists worked tirelessly, not daring to rest for a single day.
Time slowly passed under these circumstances, and in the blink of an eye, another six hundred years went by.
Li Qingsong quietly traversed the vast distance of 50 light-years through day-to-day navigation.
Currently, the fleet is more than 80 light-years away from the solar system. The sun, as seen from here, has had its apparent magnitude reduced to about 7.
The faintest stars visible to the human eye under ideal conditions have an apparent magnitude of about .
This means that the sun is no longer visible to the naked eye.
Li Qingsong looked at the starry sky and saw the myriad stars. But among those stars, the sun was no longer present.
"In the blink of an eye, a thousand years have passed..."
Li Qingsong sighed softly.
In recent years, although he still couldn't develop technology as recklessly as he could in a galaxy with abundant resources, carrying so many supplies had at least supported a certain degree of technological progress.
After a thousand years of perseverance, Li Qingsong's technology had made significant progress in various fields.
On the application front, whether it was the spaceship hull, radar detection, electromagnetic gun components, propulsion systems, nuclear reactors, or even chemical engineering, metallurgy, casting, and so on, almost everything had improved compared to before the departure.
Li Qingsong had even updated and iterated the blueprints of his various spaceships three times in the simulator. It is estimated that the overall performance of the latest generation of space carriers could be improved by a full 10% compared to the current ones!
This is an improvement in overall performance, which is a huge leap.
Unfortunately, this is just an estimate. Due to limited resources, Li Qingsong has not yet built even one new type of spaceship.
On the basic theoretical front, Li Qingsong comprehensively integrated all past theories, accumulated a lot of observation data on the strong nuclear force, quark-gluon plasma, etc., and better incorporated the strong nuclear force into the framework of the Standard Model.
Significant progress has also been made in condensed matter physics, quantum physics, mathematical principles, and other aspects.
The improvement in biotechnology is also enormous.
Based on the continuous iteration and improvement of the Nuwa AI, and the full genome analysis at the molecular level, Li Qingsong tried to use new technologies to manufacture a batch of clones. Through generations of optimization and iteration, his maximum consciousness connection number has slowly increased to about billion, an increase of a full 50%!
A maximum consciousness connection number of billion means that he can awaken almost all of the 3 billion clones.
After all, considering the necessary rest and rotation time, nearly twice the maximum consciousness connection number of clones is enough to use, so it won't be so extreme.
However, also due to limited resources, Li Qingsong did not awaken the 1 billion clones, but still maintained the situation of keeping 2 billion clones awake.
Overall, the technological progress of this millennium voyage can be described as enormous. However, there is still some distance to go before truly unifying the strong nuclear force and breaking through to a strong nuclear civilization.
Now, a thousand years have passed. No matter how frugal he was, the supplies he carried at the time of departure have been almost exhausted.
It is necessary to choose a star system to dock in and carry out some resupply.
As early as hundreds of years ago, Li Qingsong had already begun to prepare for the fleet's docking and resupply, and had begun to select a suitable star system.
After determining the target, he has been consciously adjusting the fleet's course for hundreds of years, constantly approaching this star system.
At this moment, the fleet is only about light-years away from the target.
It is a steadily burning, stable star in its prime, about billion years old, with a mass and size slightly smaller than the sun.
It has a sufficiently large planetary system inside, but it is not as chaotic as the Altair system, making it a good place to stop for resupply.
Under Li Qingsong's order, the fleet sailed towards this yellow-reddish star.
When the distance and direction were adjusted appropriately, Li Qingsong finally issued the first deceleration order in a thousand years.
In an instant, the main engines of tens of thousands of large spaceships and space carriers, which had been silent for a thousand years, started simultaneously, and at the same time, they started a violent injection towards the star. Under the propulsion of these countless engines, the faint deceleration gravity that had disappeared for a thousand years reappeared in the spaceship.
After decades of deceleration, the huge fleet finally entered the star system.
Looking at the bright star from afar, and looking at the huge gas giant and multiple rocky planets in front of him, Li Qingsong did not feel the excitement of finally arriving in a resource-rich star system, but was full of disappointment.
Because Li Qingsong knew that no matter how many resources there were in this star system, they did not belong to him.
This time, he would not be able to carry out a large-scale update of the fleet, nor would he be able to apply the technology developed and accumulated over the millennium to the fleet, nor would he be able to carry out large-scale scientific experiments here, regardless of material losses.
All he can do is to complete the material collection work and the construction of the disguised fleet as quickly as possible, and at most, he can update and replace the key parts of the fleet, and then he will have to set sail again and escape from here.
The entire berthing time, Li Qingsong only planned 30 years.
There is no way. The mechanical disaster may catch up here at any time, and Li Qingsong really dare not delay any longer.
Fortunately, his maximum consciousness connection number has increased to billion. Otherwise, 30 years may not be enough.
"Let's start building."
Li Qingsong gave the order listlessly.
Although he was disappointed, he did not dare to delay the construction action for a moment.
Under Li Qingsong's control, countless industrial spaceships landed on rocky planets or satellites, countless Jupiter planes entered gas giants to collect deuterium, and under the control of Shen Gong AI, countless robots and intelligent machines began to work, and factories began to rise from the ground, and then began to roar day and night.
In just a few years, this strange and dead star system began to prosper, but it only lasted for more than 20 years before it quickly became deserted again.
The material collection work has been completed.
The fleet repair, the replacement of necessary parts, the manufacture of disguised shell fleets, and the placement of hydrogen bomb traps in this star system have all been completed.
Then, it's time to leave.
Like a traveler who stays in a hotel for one night and hurriedly embarks on the journey at dawn, the passage of the past 30 years is like a dream.
A total of six fleets sailed in different directions again, looking at the gradually shrinking and dimming star.
Li Qingsong gritted his teeth secretly in his heart: "This time, we must conquer the basic physics theoretical barrier and break through to become a strong nuclear civilization!"
