Mining with the Planet Destroyer Cannon
Upon arriving in the new Star System, humanity, like a beggar who had been starving for many days, rushed to Rocky Planet they saw, mining there extensively. In order to improve mining efficiency, they even used many weapons originally intended for war.
Yes, it's true that humans have the Nano Mining Robot Little Grey, and it's also true that the minerals mined by Little Grey will directly turn into various metallic elements. However, if Little Grey is allowed to mine on its own, it will still have to search and dig holes on the planet. Especially when digging holes, it needs to dig down little by little, just like when humans saw the planet where Silver Mist was located.
For humanity, which was already thirsty for resources and urgently needed to upgrade its entire civilization, this was simply too inefficient. So after some discussion, humanity decided to use Planet Destroyer Cannon to mine resources.
The only known Planet Destroyer Cannon in human history is currently mounted on the Lyra.
This Star System has two Main Sequence Star. One is a very common Red Dwarf Star, with a mass about 0.4 times that of the Sun. Stars of this type have very long lifespans, remaining stable for about 200 billion years. The other is an A-type star, with a white surface and a mass about 2.5 times that of the Sun. Because of its large mass and volume, it burns fuel at a faster rate, making it much brighter. Compared to the Sun, it is 25 times brighter, but its lifespan is much shorter, only about 1.3 billion years.
Therefore, if you were to look at this Star System from a distance in space, you wouldn't see a Binary Star System, but only the brighter star. In fact, most Star System in the sky are not single stars; most are Binary Star System, followed by triple systems, then single-star Star System, and finally, systems with more than four stars are extremely rare.
Therefore, the Star System that humans have come to is one of the most common Star System in the universe. It has two stars. The smaller Red Dwarf Star is so small that its trajectory looks like that of a planet of the larger star. However, through orbital calculations, it can be known that the two stars are actually moving around a common center of mass in the Void.
Of course, this center of mass is based on the stationary reference frame of this Star System. If we also take into account their orbital velocities within the Milky Way Galaxy, then this center of mass will also move.
However, regardless of the frame of reference, humans have ways to accurately calculate their trajectories, so the fleet's activities into the star system are naturally no problem.
There are a total of fourteen planets in its system, three of which are Gaseous Planet located in orbits seven, nine, and fourteen respectively. The rest are all Rocky Planet. Moreover, the three Gaseous Planet have many moons, and the eleven Rocky Planet each have one to three moons. In total, there are more than one hundred moons of different sizes, making it a resource-rich system.
Based on the normal metallicity of a typical Star System, this Star System is more than enough for human use. It has Rocky Planet from which various Heavy Metal can be obtained, as well as Gaseous Planet from which gaseous substances such as hydrogen, helium, sulfur, methane, and Carbon Dioxide can be extracted, making it an ideal place for resource acquisition.
This binary system lacks Asteroid Belt and Kuiper Belt similar to those in our Solar System, making the space within the system relatively clean, and there are no comets. This is likely due to the large mass of the A-type star and the three Gaseous Planet in its orbit; astronomers speculate that over a long period of time, they have Gravity cleared the surrounding orbits.
As soon as the human Great Fleet entered the Star System, it deployed all its Engineering Ship and mining ships. The Main Civilization's Residential Spaceship Cluster headed directly to the Gaseous Planet in the seventh orbit. This was because the gas giant was located in the middle orbit of the star system, which would be relatively close to the main human spaceship cluster no matter where it followed the Gaseous Planet.
Humanity plans to place various engineering platforms outside the planet's orbit, and then concentrate resources here to begin building upgrades.
After some exploration, humans discovered that most of the planets in this Binary Star System have cooled cores, while only a few planets closer to the center still have hot cores due to Gravity pull and star heating.
After obtaining the data, humanity chose to launch its first violent mineral mining operation on a planet in the orbit of the Fifth Planet.
The Lyra, about the size of an island, quickly arrived near the star, but instead of entering the planet's near or Low Earth Orbit, it moved to a distance of about one Astronomical Unit in space. Then, it aimed its massive cannon at the planet, which, just as it had done countless billions of years ago, was slowly orbiting a Binary Star System.
"Warp Engine shut down, conventional power fine-tuning complete, Lyra has reached its destination, 168,320 kilometers from target, warship Attitude Adjustment complete!"
"Target planet designation: Red White-5 Planet. Specific parameters are as follows: mass 8.7457 x 10^24 kg, average density 5998 kg/m³, diameter 15560 km, orbital length, and semi-axial length of its rotational orbit."
"All functional facilities are operating normally, and the Antimatter energy system's rated output force field acceleration rail has entered the pre-start state!"
"The Antimatter warhead of the Planet Destroyer Cannon has been loaded into the chamber; all data for the Planet Destroyer Cannon are normal."
"The Planet Destroyer Cannon is ready!"
Inside the Lyra, reports rang out in the internal communications of various departments, while at the same time, the Lyra's fire control system locked onto the target planet.
This planet is slightly larger than Earth. Its core has cooled, making it a dead planet. It lacks an atmosphere and is a typical Rocky Planet in the universe. It has two moons in its orbit: one is perfectly spherical, while the other, due to its small mass, does not exhibit a perfectly spherical shape.
Humanity plans to blast it apart with a single shot, then deploy Mining Ship and nano-mining Little Grey to harvest resources from its planetary remains. Clearly, this is a brutal method of mining, essentially turning the planet's environment into something akin to mining resources from an asteroid in space—a highly convenient approach for Wandering Civilization.
However, only a civilization like humanity, which possesses Planet Destroyer Cannon, could accomplish this.
"The Lyra's Propulsion System has restarted; the anti-recoil damper readings are normal. All crew members, please enter Human Body Overclocking mode. Planet Destroyer Cannon firing countdown: 10, 9, 8, 7, 6."
A moment later, the Planet Destroyer Cannon entered the launch countdown.
The Lyra has two piloting modes. One involves all eight thousand pilots connecting to the consciousness link system to pilot the warship from Third-Person Perspective. This mode is very convenient, but it's generally used only during combat. Under normal circumstances, the other piloting mode is used, which is the traditional multi-person cooperative control mode.
This model is not much different from that of Level 3 Civilization, where each person is responsible for their own part with the help of Artificial Intelligence, which is why various voice broadcasts appear.
Humanity's Planet Destroyer Cannon has Antimatter warhead. The Antimatter is sealed in the head of the cannonball using powerful Gravity Potential Well Technology. From its appearance, the cannonball looks more like a familiar intercontinental ballistic missile.
