The numerous satellites launched by Li Qingsong decades ago have already entered the inner solar system, orbiting the sun, the eight major planets, or the satellites of the major planets and dwarf planets, collecting all the information about them; A larger-scale deep space communication network that even covers the entire solar system has been built. At this moment, there are hundreds of communication satellites distributed in different nodes of the solar system, which can communicate with Li Qingsong at any time, allowing Li Qingsong to connect to each satellite; The second generation of secondary booster thrusters has been successfully developed, which are more stable, safer and more reliable, smaller in size and mass, but more efficient; The resources of Enemy Star and Rosen Star are close to being exhausted; It is estimated that in about 260 years, the huge fleet of the Bluetook civilization will arrive. So, let’s go, let’s go, it’s time to go back to where we are closer to the sun and where there are more abundant resources. Only there can I develop better and without restrictions; Only there can I have enough resources to support my development to a higher technological stage, and only there can I have hope of fighting against the Bluetook civilization that has come from afar... At this moment, on the enemy star, the last batch of clones, as well as the final mechanical equipment and basic resources that needed to be taken away, and the most critical resource, the yellow cake, which Li Qingsong valued the most, have all been loaded onto the ship. There is no clone left on Enemy Planet now.
Tens of thousands of factories that used to roar all day long have now all stopped operating. The trains that usually run fast on the tracks that run all day long are now no longer seen. The electromagnetic catapult base, which used to be busy with cargo transportation and ejected cargo boxes into space all day long, has now become quiet. "I can't move these resources and equipment myself, but I can't leave them to my opponents either." Li Qingsong thought about it and controlled several warships to directly launch hundreds of interstellar missiles with atomic bombs loaded in their warheads. Then the next moment, it seemed as if hundreds of suns suddenly appeared on the desolate, silent and dim surface of the enemy planet. The violent heat and radiation swept across everything. In an instant, countless solid gases were sublimated directly, dissipated into space and disappeared. Those tall, solid, and seemingly indestructible steel structures became as weak as paper under this violent energy and disappeared in an instant. They were also vaporized. Even if they could cool down later, they would only condense into dust and merge with the ground of the enemy planet. It is impossible to separate them unless they are re-smelted. After clearing out everything that was left on the enemy planet, this heavy cargo ship, accompanied by several combat ships, embarked on the journey back to the planet Luoshen. At this moment, a new round of construction has begun on Luoshen Star. This round of construction is different from any previous rounds because this time, Li Qingsong has only one goal. Li Qingsong wants to build an unprecedented large spaceship. Supported by the last batch of materials that could be mined from Enemy Star and Rosen Star, countless factories began to roar again, and countless clones began to work again. The dual-purpose spacecraft that travels back and forth between space and the earth's surface is also constantly shuttling back and forth, without stopping for a moment. The space is divided into a total of 50 construction sites, and 50 of these unprecedented large spaceships are being built at the same time! In the past, even the largest heavy cargo spacecraft could be built in just a few months with Li Qingsong's efficiency. However, Li Qingsong has spent two years to complete this spacecraft and has not yet completed it.
It took Li Qingsong three years to build the main frame of the large spacecraft, and another year to complete the installation and commissioning of its internal equipment, the laying of pipelines, and other tasks. At this moment, what appeared in front of Li Qingsong were 50 square, standard spaceships that were like rectangular cubes. The spacecraft has an unprecedented length of 1,200 meters, a width of 400 meters and a height of 20 meters. This spacecraft does not have a uniform shell. It is made up of what looks like steel pipes from a distance. The diameter of each steel pipe is about 5 meters, and the distance between two steel pipes is 95 meters. In this way, a total of 4 steel pipes with a length of 1,200 meters make up one layer. Within this 1,200-meter length, there is also a 400-meter-long horizontal steel pipe crossing it every 95 meters. There are 12 horizontal steel pipes in total. Four longitudinal steel pipes and 12 transverse steel pipes cross each other to form this big net. Each grid on this large net has an area of about 9,000 square meters. Taking into account the height of 20 meters, its volume reaches about 180,000 cubic meters. There are a total of 33 such grids on this spacecraft. The last row of three grids is used to install spacecraft thrusters, equipment compartments, etc. Li Qingsong installed 10 larger secondary boosters in each of the three grids. Three grids means 30 engines. Each of these engines can propel a giant cargo ship weighing hundreds of thousands of tons to accelerate. But at this moment, these 30 huge engines are gathered together to propel this spaceship. In addition to the three occupied grids, a spacecraft like this can still use 30 grids. Each grid can transport about 300,000 tons of cargo. 30 grids means 9 million tons. Including the weight of the spacecraft itself, the mass of this spacecraft exceeds tens of millions of tons! Li Qingsong felt that it was no longer appropriate to describe such a huge and high-mass spacecraft as a cargo ship. It's not a cargo ship, but... an aerospace carrier! It was an aerospace mothership of the same type as the Bluetuk mothership that they had captured. It could be a docking place for other spacecraft and could transport an unimaginable amount of supplies! At this moment, all 50 aerospace carriers have been manufactured, and it is time to load supplies, equipment and personnel. A large number of small spaceships began to gather towards the aerospace mothership like ants. During this process, huge cargo boxes, spaceships of various sizes, and numerous ecological cabins for clones, livestock, and poultry to survive, either took off directly from the surface or were completed in space factories, and then came to the aerospace mothership and were fixed to the grid of the aerospace mothership. Almost endless amounts of liquid hydrogen, liquid oxygen, methane, ethane and other chemical fuels, as well as large amounts of uranium 235 and plutonium 239 were also poured into the fuel tank. It took Li Qingsong almost a year to complete the transfer and loading of all personnel, materials and equipment. So...it's time to set sail.
