Comprehensive Upgrade
After bombarding the planet, the Lyra turned and left. Other Mining Ship would come to mine, either by pushing away the rocks with their thrusters like they were capturing asteroids, or by bringing their Smelting Platform to the vicinity, or by releasing the Little Grey for nano-mining.
Regardless of the method used, or even several methods combined, this mining method is far more efficient than slowly digging inside a planet by sending a spaceship into the interior.
Such mining methods would have been unthinkable in the past, showcasing the full power of Level 4 Civilization. Seeing the entire planet explode, some of the older residents couldn't help but recall the Silver Mist that humanity encountered when they first ventured into space. If they had possessed such methods back then, a single shot would have wiped out the Silver Mist.
After blasting this planet, the Lyra turned to other planets and continued to bombard them. Every planet that humans set their sights on was inevitably shattered into space mineral deposits by a single blast.
Of course, the Lyra didn't continue its wanton destruction indefinitely. After bombing five planets, it had probably met some of its resource needs and temporarily stopped. Yes, only temporarily, because humanity at this stage hadn't yet completed its Level 4 Civilization upgrade, so capabilities like space transportation hadn't been fully utilized.
Therefore, the first step after humans obtain resources through mining is to build new production and transportation tools on a large scale, such as transport ships, Mining Ship, and Engineering Ship with Warp Speed Travel capabilities. After these are built, the scale of mining is expanded and the efficiency of resource acquisition is improved. Only then will the process of upgrading and replacing these with Residential Spaceship, Biosphere Spaceship, and large equipment transport ships begin.
As for the obsolete Residential Spaceship, humans will not discard them. Instead, they will be brought back to the shipyard for modification, equipped with Warp Engine, and then given to several Affiliated Races such as the Crimson Flame Civilization and the Kuntai People Cluster to be used as Residential Spaceship.
As Affiliated Races and vassal civilization, it is only natural that their spaceships are smaller than those of humans. Of course, individuals of the Affiliated Races have made contributions to science are not stingy and will be given spacious new Level 4 Civilization Residential Spaceship as their residences. Moreover, such living conditions will be publicized in the societies of each of their races, and the purpose is self-evident.
It was to make them understand that only by making scientific contributions to the entire group could they have better living conditions.
Who doesn't yearn for better living conditions? While you're still living in a cramped spaceship that uses rotational inertia to simulate gravity, and while you're still living in rooms made up of individual cabins, others have already boarded spacious Level 4 Civilization spaceships. Envy is useless; only by working hard to contribute to the community can you enjoy such an environment.
Such differences in living environments can, to some extent, motivate the efforts of other races, which is beneficial and harmless to the entire Human Civilization cluster.
In the comprehensive upgrade plan for creation, humanity will not only upgrade the creations of its own civilization, but also take into account other races, since they still need to travel through the universe with humanity. Their Level 3 Civilization spaceships must be upgraded and modified to keep up with the main force.
However, other races upgrade their creations later. Humans will first fully upgrade their creations and arm themselves to the teeth before considering subordinate civilizations and Affiliated Races.
Time always flies by in the starry sky. The great construction era that followed the Lyra's devastating bombardment of a star was measured in centuries. After several centuries, humanity finally completed the upgrades to all the ships of its civilization.
Then, over several centuries, 2,990 Planet-Class Warship were built, connected by a 'Synchronized Consciousness' device. These warships, along with the Lyra, would form humanity's most elite fleet.
Although they were not manufactured to the high standards of the Lyra, their main framework did use some Strong Material. This was unavoidable; the production of Strong Material was extremely difficult. If they were all manufactured to the Lyra's standards, it would take at least ten thousand years to complete the construction of three thousand warships, and the time cost would be too high, making it not worthwhile.
If upgrading spaceships such as Residential Spaceship, Engineering Ship, Mining Ship, Biosphere Spaceship, and Research Ship represents humanity reaching a Level 4 Civilization in terms of life and production, then the appearance of these 2,999 warships is the symbol of humanity officially possessing Level 4 Civilization combat power.
And that's not all. A mere three thousand Planet-Class Warship cannot meet humanity's security needs, so humanity will continue to build new ones, which will also be Planet-Class Warship, but ordinary Planet-Class Warship without 'Synchronized Consciousness' equipment.
Humanity's plan for this stage was to build a fleet of three million Planet-Class Warship, which would still be divided into three fleets: the First Fleet directly led by Lyra, the Second Fleet led by Jupiter, and the Third Fleet led by Saturn.
Yes, Jupiter and Saturn.
These two warships were planned to be built when the batch of 2,990 warships was being produced. They were specifically designed to serve as the flagships of the Second and Third Fleet. Their performance and configuration were actually similar to other warships in the same batch, except that they had many more pieces of equipment for overall command and control.
Because the time and cost of manufacturing Strong Material were too great, these two warships were unable to be equipped with Planet Destroyer Cannon like the Lyra, due to structural strength limitations. Therefore, they had to settle for larger Neutron Kill / Neutron Burst as their main guns. Of course, other weapons such as Gravity Bomb and Warp Speed Missile were also included.
As things stand, due to time constraints, humanity can only possess one Planet Destroyer Ship at present.
As for why there are only three million other ordinary warships, the main reason is the time and cost of shipbuilding.
Planet-Class Warship of Level 4 Civilization are far more complex than those of Level 3 Civilization, and the amount of resources required to build them is also exponentially greater. Even with fully automated production, the time cost caused by the complex processes cannot be ignored. Therefore, unless Level 4 Civilization has existed for a very long time, it generally does not have many Planet-Class Warships.
From this perspective, the fleets of Level 4 Civilization are actually much smaller than those of Level 3 Civilization. However, the smaller number is only temporary, because time will add up everything, and a smaller number does not necessarily mean weaker combat power.
Humanity spent almost another thousand years in this Binary Star System to create and upgrade various Level 4 Civilization artifacts. After completing all this, there were very few Rocky Planet left in the entire Binary Star System, and even the Gaseous Planet had shrunk somewhat due to the constant absorption of elements such as hydrogen and helium.
