On Luoshen Star, Li Qingsong felt a chill in his heart. The actual close observation of the probe lasted only a short time, but this short period of observation was enough for him to understand a lot of information. My opponent is very strong. This can be seen not only in their ability to build larger spacecraft, but also in their propulsion technology. Humans have already mastered ion propulsion technology and have applied it on a large scale. The principle of this technology is to first ionize the working fluid - that is, the substance that is ejected and uses the reverse thrust to propel the spacecraft to move - and then use the electromagnetic field to accelerate the working fluid ions to an extremely high speed and then eject them from the nozzle. Because the speed of the working fluid ions is extremely high, even up to 10,000 to 20,000 kilometers per second, far exceeding the injection speed of chemical fuels of several to more than ten kilometers per second, a unit mass of working fluid can provide a reverse thrust far exceeding that of chemical propulsion, thereby contributing to higher propulsion efficiency. However, this technology has great limitations. Although its specific impulse is high and the working fluid utilization rate is also extremely high, the overall thrust per unit time is extremely small. To put it simply, one unit of chemical fuel thrust can accelerate a one-ton object from zero to ten meters in one second, but it can only last for three seconds, so the total acceleration is thirty meters. Ion propulsion, however, is that if the same mass of working fluid is used using ion propulsion technology, the maximum it can achieve is to accelerate a one-ton object from zero to mm per second within one second, but it can last for a full year, so the total acceleration reaches meters, far exceeding chemical fuel propulsion.
In the human world, ion propulsion technology is basically unable to meet the needs of rapid maneuvering of large mass objects and is only used in needs such as maintaining satellite orbits and slow acceleration of long-distance spacecraft. The advantages and disadvantages of ion propulsion are obvious. So... what if there is a technology that can solve the disadvantages of ion propulsion while retaining its advantages, that is, while retaining its advantage of ultra-high specific impulse, solving the problem of too little thrust? This is the high-speed ion propulsion technology that the human world has always dreamed of! People imagine that once they master high-speed ion propulsion technology, they may even be able to create spacecraft capable of long-distance interstellar voyages! However, high-speed ion propulsion technology is too profound and the human world has never been able to master it. As a last resort, they can only settle for the second best and temporarily develop secondary pressurized injection technology, which is the propulsion technology used by the Deep Space spacecraft at this moment, as a transition. And now... Li Qingsong saw the practical application of high-speed ion jet technology from these unknown spacecraft! Based on this alone, Li Qingsong was able to judge that the opponent's technological strength was far superior to his own and far superior to human civilization before it disappeared. Coupled with the huge spaceship, Li Qingsong had enough reason to believe that they came from other galaxies. So there is a problem. What are you doing in the solar system? What is so special about the solar system? After much thought, the only special thing about it is that it is a galaxy with intelligent civilization. Apart from intelligent civilization, Li Qingsong doesn't think there is anything special about the solar system. So what is your connection to the disappearance of humans? What role do you play in this incident? Li Qingsong's millions of brains were thinking about this question at the same time, but it only lasted for a moment and then stopped on its own. Now is not the time to pursue this issue. The most important thing now is that they are flying towards me! Judging from the current situation, their mother ship, that is, the large spaceship, seems to have suffered accidental damage, so it has to temporarily dock in the orbit of Enemy Star and use the resources of Enemy Star to recover itself. Perhaps they did not attack him directly at the beginning, but only used the cluster of strange birds to kill him, because they were in the early stages of repair and were temporarily unable to destroy him. And now, after decades of recuperation, they have recovered a certain degree of strength, so they can't wait to embark on an interstellar voyage to destroy themselves! For a civilization that has mastered high-speed ion propulsion technology, how advanced would its offensive and defensive technologies be?
I can't possibly be his opponent! At least if we fight head-on, I'm sure I can't beat him! Li Qingsong immediately made this judgment in his mind. So...what should I do? In the face of this unprecedentedly powerful opponent, Li Qingsong remained calm and composed. Taking into account his own advantages, his own technical level, the advantages and disadvantages of his opponent, etc., a plan quickly formed in Li Qingsong's mind. "I don't care what your plans are or what your background is. At least at this stage, the strength you have shown to me is just these dozens of small spaceships. If we fight head-on, I probably won't be able to defeat these dozens of spaceships, but it doesn't matter, I must be crazy to think of fighting you head-on!" At this moment, Li Qingsong decisively issued orders to the million clones he was controlling at the same time. Except for the jobs necessary to maintain the base's own operation and the survival of the clones, all other non-essential jobs have been stopped. This immediately mobilized up to 900,000 awareness link shares. The next moment, these 900,000 consciousness link shares and their corresponding clones were all invested in one thing. Make guns! If you can’t make more advanced guns, make gunpowder guns! Make a lot of gunpowder guns! With the temporary suspension of operations of many unrelated factories, all factories related to guns and bullets were thrown into a frenzy of busyness. Many mines suddenly began to increase their production rates. Numerous excavators and crushers roared wildly, mining large chunks of ore. The train was running frantically, transporting the ore to the metallurgical plant at an unprecedented speed. The blast furnace spewed out black smoke, and the hot molten steel rolled out like a flood. After cooling and taking shape, it was sent to the processing plant and turned into parts under the operation of countless machines. The chemical plant was also running frantically, sending large amounts of gunpowder to the bullet factory, which was processed into bullets of standard specifications, which also flowed down the conveyor belt like a flood. While starting the frantic process of making guns and bullets, Li Qingsong also ordered that all of his 500 Mercury-class battleships that were stationed around the space base be transferred back to the surface of Luoshen and then into the huge factory. It wasn't long before all these warships appeared. But this time, they did not stay in space again, but started to accelerate madly, and with the support of the deep space communication network, they rushed towards the enemy planet madly. Another three updates are completed, please vote for me and keep reading!
