Inside the Earth-class battleship, under the control of a total of 688 clones, and with the assistance of the Earth-A tactical version of Goku, Li Qingsong's will was thoroughly implemented. The 16 small nuclear fission reactors and 16 internal combustion engines equipped inside the spacecraft were started at the same time. A large amount of chemical fuel was sent into the combustion chamber to begin burning, generating high-temperature and high-pressure gas, which was then sent into the fission reactor under magnetic confinement for secondary pressurization. Finally, this gas with extremely high temperature and pressure was violently ejected from the 16 thrusters installed at the tail of the battleship. At the same time, a total of 32 attitude adjustment thrusters distributed throughout the spacecraft's hull, controlled by the 17th secondary pressurization system, were also started simultaneously, controlling the battleship's hull to slowly turn. The speed of this Earth-class battleship increased at a not-very-fast but extremely determined rate, and it eventually broke free from the gravity of Ganymede and flew into the vast space. With the huge Jupiter as its backdrop and under the dazzling sunlight, this Earth-class battleship soars freely in space. After testing its maneuverability and engine performance for a period of time, a fleet of Mercury-class battleships arrived thousands of kilometers away from it and poured heavy fire on it. In an instant, tens of thousands, hundreds of thousands of high-speed electromagnetic cannon projectiles came rushing in like an irresistible torrent. But the next moment, the high-speed radar network was activated. Under the surging power supply of the fission reactor, a total of 1,024 deep space scanning modules continuously scan the surrounding airspace, and determine the orbital data of numerous tiny electromagnetic cannon projectiles. This mountain of data was rapidly transmitted to the central supercomputer. With the parallel operation of more than 2,000 high-performance 2-nanometer chips, the counterattack data was calculated in an instant. Then the data was quickly transmitted to each high-speed bogie, controlling them to complete the steering of the electromagnetic gun and laser cannon within a few tenths of a second.
Countless tiny electromagnetic cannon projectiles and tiny laser beams were fired. In order to increase the success rate, every incoming electromagnetic cannon projectile will face the interception of dozens or even hundreds of projectiles! And during this process, the scanning of the high-speed radar network will continue without stopping, constantly updating the situation of the surrounding airspace and continuously transmitting data back to the supercomputer. The supercomputer will continue to calculate and continuously transmit data to the high-speed bogie and defense weapons. At the same time, offensive weapons were activated after sensing the attack. More than 100 large electromagnetic cannons and laser cannons immediately launched a counterattack. Although their number is small, their firing rate is faster than that of Mercury and Venus class battleships, their mass is higher, and their lethality is greater! There were also electromagnetic cannon projectiles and laser cannons fired in all directions like a landslide or tsunami. At the same time, four giant electromagnetic cannons and laser cannons also joined the battle. Under the irradiation of a high-energy laser beam, in just one second, the hull of a Mercury-class battleship more than 3,000 kilometers away began to boil like boiling water, with tiny metal particles flying everywhere. The Mercury-class battleship fled in panic, but the next moment, a projectile with a mass of 10 grams and a speed of 20 kilometers per second flew straight towards it. The speed of this projectile was too fast! This made the interception of this Mercury-class battleship seem weak and powerless. In a hurry, only a few micro-electromagnetic cannon projectiles hit it, but failed to completely change its trajectory. So the next moment, the projectile suddenly hit the armor. The entire spacecraft shook violently at this moment. Although the armor was not penetrated, a huge dent was directly created, and various equipment installed nearby were also directly damaged. Just one bullet caused it to suffer huge trauma! The fierce battle lasted for more than three hours, and ended with all the hundreds of Mercury-class warships participating in the siege being annihilated. Although this Earth-class battleship was also hit by some electromagnetic cannon projectiles - after all, defense interception cannot be 100% complete - but under its thick and tough armor, there were only some dents and a few pieces of equipment damaged, which can only be called superficial injuries at most. The test achieved results that satisfied Li Qingsong, but this Earth-class battleship did not return, but came to the ring of Jupiter. Among the thousands of pieces of rubble, a huge piece of rubble, the longest of which is two hundred meters long, is moving slowly under the gravity of Jupiter.
Although its size is similar to that of an Earth-class battleship, it is solid. This means that its total mass is at least over 2 million tons, more than 100 times that of an Earth-class battleship! Faced with this behemoth, the Earth-class battleship launched an attack. Endless electromagnetic cannon projectiles bombarded it violently, and in an instant, endless dust erupted from this huge piece of rubble. The fierce shooting lasted only five minutes before it stopped. At this moment, the smoke and dust had cleared, and there was no trace of the huge piece of rubble in Jupiter's rings. It was easily smashed into pieces by the Earth-class battleships and completely merged into the rings of Jupiter, and could no longer be distinguished. Feeling the powerful combat capability of the Earth-class battleship, Li Qingsong's heart was filled with joy. “You are the first Earth-class battleship I own, so you must have a resounding name. Hmm... the Big Dipper rotates around the North Star, so I'll name you after the North Star in Eastern mythology, Ziwei!" The name of this first Earth-class battleship is Ziwei! At this moment, having fully verified the performance and combat capability of the Earth-class battleship, Li Qingsong immediately began larger-scale construction. With the Ziwei, of course we also need an Earth-class battleship named after the seven stars of the Big Dipper. Tianshu, Tianxuan, Tianji, Tianquan, Yuheng, Kaiyang, Yaoguang, each of these names will have an Earth-class battleship! In addition, there will be more stars that will have corresponding Earth-class battleships. According to Li Qingsong's plan, the total size of his fleet will reach more than 70,000 ships. Among the total number of about 70,000 warships, there will be about 68,000 new Mercury-class battleships and 3,000 Venus-class battleships. The largest Earth-class battleships will number 50! In addition to these warships, Li Qingsong will also build more types of auxiliary spacecraft, such as supercomputing ships that run the strategic version of Wukong and provide data support for the entire battlefield, communication ships that support battlefield communications, reconnaissance ships responsible for reconnaissance, as well as supply ships, repair ships, and so on. The final fleet size will reach more than 75,000 spaceships!
