The Purple Thorn Civilization had contact with some Kates during those 100 years. The Kates thus learned about their language information and some civilization characteristics. Relying on these, the exploration spacecraft can obtain more information at the target location. Two years after the exploration spacecraft was launched, it was observed that a war was taking place inside the Tiancang Five star system. The war was a conflict between two civilizations. One was the Purple Thorn Civilization, and the other was the indigenous civilization inside the Tiancang Five star system. Perhaps the news of the destruction of the Purple Thorn Civilization fleet had reached Tiancang Five, which led to this war. There could also be another reason. It was different from what Yan Xia and Ella had guessed. The Purple Thorn Civilization did want to build a huge interstellar empire, but it was not an agricultural civilization like the eastern and southern parts of Asia on Earth, but a nomadic civilization like the northern and central parts of Asia.
Its expansion was like an interstellar version of the Mongol Empire. The powerful combat power pushed the civilization flat, and then left some people to govern the civilization locally. This has one advantage. That is, the speed of expansion will be greatly accelerated. This is true. In just 1,000 years, the Purple Thorn Civilization has controlled a large area of star fields. The information roughly collected by the exploration spacecraft has 4 civilizations. Although there are only 4, it means that the Purple Thorn Civilization controls more than a dozen or even dozens of star systems. After all, even if life is widely present in the universe, it is impossible for civilizations to be born in every galaxy. According to Ella's calculations, the number of civilizations controlled by the Purple Thorn Civilization may have reached 7 to 10. Such a civilization, of course, has obvious disadvantages. Not stable enough. It cannot fully control the civilization it rules. The outbreak of civil strife is also inevitable. Especially now, when its huge army falls, it means the decline of its civilization, and it falls at a faster speed than expansion. Those 1,000 warships have 97% of the combat power of the Purple Thorn Civilization. Today's Purple Thorn Civilization is like a lamb with its wolf skin taken off, a piece of delicious and greasy fat, and a peerless beauty who has taken off her clothes. "The plan can be started." Yan Xia, who received the message, was still standing on the podium. Below were students of three races. They were listening to the class seriously, but they didn't expect that this professor who had always been extremely serious would answer the message in such an occasion, and even laughed out loud.
Then, they heard the professor say: "Students, I may not be able to continue teaching in the future." Many robot soldiers walked in from outside the classroom, and Yan Xia left under their protection. That afternoon, when the students learned that the professor who had been teaching in the school was Yan Xia, they were all surprised. Of course. These were just trivial matters for Yan Xia. He had already arrived at the battleship factory not far from the Baiyan Star Civilization Port in an anti-gravity spaceship. All their battleships were produced here. It was only in the last 100 years that the large-scale production of battleships was suspended, and all production capacity was supplied to a main ship. Since the Hope spaceship completed its mission, Yan Xia had already begun to preliminarily design a new main ship as his vehicle more than 400 years ago. But then it was shelved for more than 300 years. The reason is that the technology did not meet the requirements. As the main ship, it must have the technological level of the peak of civilization. Ella applied what she developed through the string to it. This factory is located in space. It is more like a huge space fortress than a factory. It is an astonishing 200 kilometers long, 148 kilometers wide, and 32 kilometers high. In the center of this huge space fortress is the dock for producing warships. A huge alien spaceship with a mirror-like shell is quietly staying in it. It is shaped like a kayak, and 6 energy storage devices are bound around the hull with electromagnetic force. This is their main ship now. ——Tiangong The length of the entire warship reaches a terrifying 32,800 meters, but the width is only 4,628 meters and the height is only 3,872 meters, which is very slender. And each of the surrounding energy storage devices is like a huge diamond shield with an arc, each of which is 6,300 meters long. It is equipped with the most advanced dark matter decay device, which generates 16 times more energy than the positive and negative matter annihilation device. And because of the development of technology, Ella applied the latest thermoelectric conversion device on it, getting rid of the "boiling water" technology that human civilization has been working on for a long time. This thermoelectric conversion device can directly convert thermal energy into electrical energy, and the efficiency reaches an astonishing 92%, and there is no need to worry about heat dissipation at all, because the thermal energy has been converted into electrical energy. This is a very significant breakthrough, which allows them to now have an energy reserve of on a wandering planet. "The Tiangong main ship is only three months away from completion, right?" Yan Xia asked as he looked at the brand new warship from the spacecraft. Ella took over the control of a robot next to Yan Xia.
"Yes, it can leave this dock in three months." "The surface of this battleship uses the super element I studied. This element is very stable and has greatly improved strength and heat resistance compared to the metals of light civilization." "Although its half-life is only 21 million years, its density reaches ³, hardness is 24, melting point is 170,000 degrees Celsius, and strength is 54721Mpa." "The increase in density is to better make its surface into a mirror, reflecting more light and cosmic particle flow caused by the high speed of the spacecraft." "Of course, the strength of the shell is only to bear Under more acceleration pressure, its real technology lies in the four basic forces. " "The main ship of Tiangong has been equipped with four basic force shields, and also has four basic force weapons. The strongest main gun can reach 400 trillion density equivalent," "The main ship is equipped with a complete gravity system inside, which can already be done inside the warship. The anti-gravity system is also used outside to isolate the influence of the gravity of the universe. The theoretical speed of the Tiangong spacecraft can reach 20872km/s, and the actual speed should not be much different." Now they still have a gap with the Purple Thorn Civilization. After all, the Purple Thorn Civilization has a huge amount of resources, and it has been more than 1,000 years since it entered the Level 2 civilization. And now, although it has been 500 years since the observation of the string, they are still in the stage of transition from Level civilization to Level 2 civilization, and it is not a complete Level 2 civilization. But such a configuration is enough to deal with the current Purple Thorn Civilization. Yan Xia will wait for the completion of the main ship of Tiangong, and then he will take this spacecraft to Tiancang 5. Given the current distance between them and Tiancang 5, it would only take 192 years to reach there. During this period, even if the war in Tiancang 5 was over, it would be unlikely to fully recover.
