At this moment, in the orbit around Luoshen, in addition to the originally built space laboratory, another larger space base appeared. The space laboratory is long and narrow, and although it is long enough, it lacks thickness and width. Although this space base is not as long as it, it is spherical in shape with a diameter of about 600 meters. Many supports extend from it, like needles stuck into a big ball. Those are berths for spacecraft. When the spacecraft needs supplies, it can come closer and fix itself on these brackets, and then pipes will extend out to supply the spacecraft with various supplies. In addition to the material supply racks, there are also numerous personnel passages, spacecraft maintenance stations, etc. This big ball has a diameter of 1,200 meters and a total internal space of about cubic kilometers. At the core are numerous huge tanks that are stored in strict isolation strategies. A batch of tanks store liquid methane, ethane, hydrogen and the like, with a total reserve of million cubic meters and a total mass of about 800,000 tons.
Another batch of tanks stores pure oxygen, with a total reserve of 1 million cubic meters and a total mass of approximately million tons. In addition to these two most important material reserves, there is also storage space for numerous spacecraft parts, maintenance tools, shells, bullets, missiles, generators, various equipment, etc., as well as densely packed and extremely complex internal passages. At the same time, it also has Li Qingsong's most violent firepower and most powerful defense so far. Its entire shell is made of special bulletproof steel with an average thickness of 100mm, followed by a buffer layer, a blocking layer, a fiber layer, etc., with a total thickness of up to 300mm. Unless it is bombarded with artillery shells, even continuous machine gun fire will not penetrate its defense. In addition to its thick shell, it is also equipped with a variety of weapons facilities. It is equipped with 1,500 high-rate machine guns alone, 200 machine guns, and 200 interstellar missile launchers. It is also equipped with 20 high-precision radars newly developed by Li Qingsong, which can scan the entire surrounding airspace around the clock. Moreover, Li Qingsong also planned to immediately deploy at least 100 warships around the space base for protection once a battle broke out. This whole set of measures is the limit of the protection that Li Qingsong can achieve. If we can't even protect this base, there is nothing we can do. This is the first work Li Qingsong has completed in the past two years. The second task was that Li Qingsong finally formed his first space battleship fleet. More than one million clones worked desperately, thousands of huge bases and factories roared day and night, and with the abundant material support from Luoshen Star, Li Qingsong finally built 500 Mercury-class battleships! At this moment, they are parked around Space Base No. 1, guarding it and flying with it. Machine guns, cannons, missiles, radars, optical observation equipment, optical positioning equipment... All kinds of combat equipment make this fleet look murderous and majestic. Numerous cargo ships transport supplies and fuel from the base cluster on the surface of Rosene to the space base. The warships do not need to land on the surface and can directly obtain sufficient supplies from the base. Then, they broke free from the gravitational field of Luoshen with murderous intent and headed for deep space.
Here, they were divided into two teams and began high-speed maneuvers again and again, coordinating with each other again and again. A large number of blank bullets were fired, and a large number of lasers simulating interstellar missiles were emitted. For a moment, this airspace was filled with war. This is an exercise. At this moment, Li Qingsong only had some knowledge of interstellar combat from paper deductions, and had no practical experience at all. Just like when the clones used cold weapons to face the flock of strange birds, they had to quickly accumulate experience in cold weapon combat, and the same is true now. After the collective combat drill, the next step is the pursuit battle, then the melee, the planet defense battle, and so on. Because the deep space communication network had not yet been built, Li Qingsong had to temporarily lay a communication network for this exercise and have every warship enable coordinate sharing so that the exercise could be carried out. Otherwise, it would have been a mess. After a day of exercises, the fleet returned to the base. Without bothering to analyze the gains from the day's exercises, Li Qingsong first noticed a piece of data. It was just an exercise, but this fleet consumed 25,000 tons of fuel, and various blank shells and simulated shells consumed several thousand tons. Including the consumption of the clones themselves, more than 30,000 tons of supplies were destroyed. It would take 1,000 cargo ships to make two round trips to replenish these 30,000 tons of supplies. Adding the consumption of the cargo ships themselves, almost 50,000 tons of supplies were gone. "If there were fewer clones, I wouldn't be able to afford even a drill." Li Qingsong sighed. After a short rest and replenishment of supplies, the fleet exercise began again. There is no way. We don’t know when the enemy will arrive. If we don’t prepare for battle now, it may be too late later. While carrying out large-scale production, transporting materials on a large scale, and conducting large-scale exercises, Li Qingsong was also controlling tens of thousands of clones to carry out the last of the three scheduled tasks: technical research on deep space communication networks. Two years have passed, and thanks to the clones' painstaking efforts, this technology finally made a breakthrough. "Once the communication network is built, I can send a probe to the enemy planet, and the fleet can also move away from the planet into space, instead of always circling around the Roselle planet." Li Qingsong immediately mobilized his brain power, made a blueprint of the deep space communication network, and then immediately started production and construction. The most critical component of this communication network is 100 large antennas with a diameter of up to 45 meters. Originally, there was no need for so many, only 20 would be enough. However, in order to prevent them from being destroyed during the war, Li Qingsong directly increased the number fivefold. Some of these large antennas are laid out roughly evenly at the poles, equator and other parts of Rosene in accordance with a certain geometric structure, while the other parts are laid out in the orbit around Rosene. Li Qingsong has done his best to protect every large antenna, striving to maximize its survivability. In addition to these large antennas, Li Qingsong also manufactured thousands of satellites, scattered them around the star Luoshen like sand, and even launched some satellites to start revolving around the sun. Thus, a huge and dense communication network was built with Luoshen as the core. As soon as this communication network was built, Li Qingsong launched a detector.
