A large number of star systems were given to the Silk Civilization. This also means that the Silk Civilization officially has a bridgehead. They will use this as a springboard to enter deeper into the Federation. They did not wait for long. It was about 400 years. The Silk Civilization invaded again. This was already very fast, and they even planned to catch the Federation by surprise. However, there were too many detection devices in the deep space inside the Federation. These anchors made the Silk Civilization's plan fail and made their speed at least 20 years slower than expected. As the Federation's position, the Silk Civilization knew that they could not fight a protracted war. Fighting slowly would only give the Federation time to breathe, so it had to be a wave.
The number of warships attacked by the Silk Civilization this time was as many as million, which could be said to be all the family wealth. Such a large number of warships did not stretch the front line as much as before, but attacked 6 close star systems at the same time, so that they could support each other. After all, after fighting with the Federation for so long, they found that the Federation's transfer speed was too fast over a large span, while the movement speed of the Federation's warships was limited over a small span. This affected the Silk Civilization's battlefield judgment. It also affected Yan Xia's plan. "The depth of the Silk Civilization's attack has become narrow, which is beneficial to us." "Let all the spacecraft go out and surround them." Even if the Silk Civilization fleet is dispersed, he has dispersed tactics. However, for them at this stage, it is better for the Silk Civilization to gather together like this. Yan Xia doesn't have any more tactics. In the vastness of the universe, and at the same time, when everyone's civilization is so high, the ambush tactics like before are already extremely amazing. Most of the time, there will be no overly complicated tactics in cosmic wars, but the simpler the better. ... After another 70 years. The Silk Civilization fleet entered 6 star systems at the same time, not giving the Federation time to react. In these years, the Federation has been gradually letting citizens retreat to the rear, and there are not many citizens in the star system at this time. It can even be said that they still surrendered. It is unknown whether the Silk Civilization was overjoyed or alerted Yan Xia. Anyway, after 20 years, their encirclement was finally completed.
The speed of the spacecraft itself is actually much faster than that of the battleship. Because of its small size, and the Federation's propulsion technology is now quite advanced, some smaller spacecraft can reach more than 38,000 km/s. This is equivalent to a spacecraft traveling a distance of 1 light year in less than 8 years, which was completely unimaginable in the past. Such a fast speed also allows them to quickly reach the designated location and encircle the Silk Civilization. Encirclement in the universe not only needs to consider the front, back, left, right, but also the top and bottom, so it is not easy. It can be said that a comprehensive 360-degree encirclement is a real encirclement. Fortunately, there are enough spacecraft. In fact, even if there are enough, it is impossible to cover the entire sky. After all, they are besieging 6 star systems. Even if these 6 star systems are closer, there are still a few light years. Therefore, these spacecrafts shrink their range as much as possible to make the distance between each other shorter, so as to prevent the warships of the Silk Civilization from being able to break through directly in a group. This requires the spacecraft to have a certain degree of concealment. Therefore, Yan Xia invested some funds to connect the energy of the spacecraft in series, so that the spacecraft can transmit unlimited energy at close range. This energy connection will make the spacecraft a whole, and use these energies to hide in the spacecraft cluster. It uses the simulated radiation formed by wandering energy. There are various kinds of radiation in the universe, which make the vacuum not a vacuum, and make it impossible for all places in the universe to be absolute zero. It is very easy to hide yourself in the universe like being invisible. But you hide visible light, invisible light, natural entropy increase and unnatural entropy decrease of objects, gravity of objects, and the influence of objects on the surroundings, all of which will lead to discovery. The hiding method of these spacecraft is cosmic microwave mimic hiding, which uses energy transmitted infinitely between each other to simulate, so as to achieve the hiding effect while avoiding excessive waste of energy. These mimicked energies have clear transmission directions and can be received and reused by spacecraft in the transmission direction. The only downside is that this hiding method is not that strong. It is just a little more advanced than the general hiding method, and it is far from reaching the level of [Wall]. But Yan Xia does not need them to have strong hiding properties. They only need this point. As long as the encirclement is reduced to within 5 light years, everything will be successful. Yan Xia's fleet is far away. He uses Ella's simulation calculation to observe the movement of the spacecraft at this time. There are dozens of holographic images in front of him. The process and results of each image are different. These are also the most likely results. Play them over and over again. "So our point is here." "Although our encirclement is as small as possible, it is not extremely small. This is the point." "If it exceeds this point, the expected effect will not be achieved." When the encirclement is small enough, the Silk Civilization will directly attack the encirclement. They will use large-scale weapons. Since the density of the spacecraft itself is high, large-scale weapons will destroy excessive spacecraft. At this time, from the perspective of cost, it is a win for me.
Yan Xia needs these spacecraft to launch an attack before reaching this critical point, so that the Silk Civilization can observe the fact that it is surrounded. The response of the Silk Civilization will be to choose a direction to break through, so according to the movement of the Silk Civilization fleet, they can make adjustments at any time. The speed of the spacecraft is not much slower than that of the Silk Civilization warships, and there is a certain distance between them, so at this critical point, the Federation's spacecraft must move faster. Yan Xia can only wait for the action of the Silk Civilization, because there are too many possibilities, and he can't know what the Silk Civilization will do in advance. All the decisions of the Silk Civilization must be based on the most perfect results of supercomputing analysis, which is the most headache for him. Although civilizations such as the Olive Branch Civilization have not developed artificial intelligence, the computing power level of their civilizations is actually much higher than that of the Federation. Yan Xia also learned why the Olive Branch Civilization did not develop artificial intelligence. Later, he discovered that the life of the Olive Branch Civilization itself is artificial intelligence. This is easy to understand. Since the Olive Branch Civilization is a mechanical individual, how did their number of lives increase to the terrifying tens of trillions or even hundreds of trillions? The real reason is that most of the lives of the Olive Branch Civilization are not actually transformed from real lives, but are fundamentally creations. However, these creations are endowed with the same thoughts, feelings, values and powers as other Olive Branch lives. In this case, the Olive Branch Civilization does not need something like artificial intelligence, because if it has artificial intelligence, how can ordinary life be separated from artificial intelligence? This is like the Federation giving some robots the status of Federation citizens, while other robots choose not to give it, which is bound to cause contradictions. Now Yan Xia has not seen the original body of the Silk Civilization life, which also makes Yan Xia guess that the Silk Civilization may also be a mechanized civilization. How a mechanized civilization thinks is even more difficult to analyze. Yan Xia waited. Waiting for the Silk Civilization to respond.
