The Earth Star Kingdom formed an expeditionary space fleet in order to deal with the Dyson Ball plan of the Heavenly Court. In order to find out the progress of the Dyson Ball, Wei Xinyu decided to visit the Zhenbei Observatory of the Earth Star Kingdom Observatory.

Wei Xinyu got off the plane and took a special car at the Zhenbei Observation Station. He drove for about 30 minutes. On the Gobi Desert 35 kilometers east of Zhenbei City, an altitude of 4,000 meters, 35 kilometers east of Zhenbei City, a huge white ball stood among the bare mountains, wrapped in a sun-radio telescope, patrolling the dazzling galaxy day and night, and using a computer to depict the observation of the sun.

Wei Xinyu walked into the office of Zhenbei Observation Station, and a tall and thin man received him:

"My name is Wang Lin, and I am the stationmaster of Zhenbei Observation Station. Yesterday, I went to the call of the Ministry of National Defense of the Earth Star Kingdom and said that you will learn about the data on observing the sun at our observatory today. I asked our observers to sort out the data overnight. We have entered all the observation data on the sun in recent years into the U disk, so that you can bring it back to study."

As he said that, webmaster Wang Lin handed a USB flash drive to Wei Xinyu.

Wei Xinyu put the U disk into his briefcase and asked: "Did you find anything strange about your observations of the sun in recent years?"

Wang Lin held his glasses with his hand and said, "In recent times, we have found a large number of covers appearing between the earth and the sun, causing a sharp drop in brightness. However, after analyzing this, we later believed that the only thing that blocks the sun was the dust belt around the sun, not the "Dyson ball" of aliens or super civilized aliens."

Wei Xinyu asked in a suspicious tone: "Are you sure?"

Wang Lin thought for a while and said, "I can't be completely sure that although our Zhenbei Observatory is the first radio telescope in the Earth Star Kingdom, it observes the sun through radio waves emitted by the sun. It can be not limited by optical telescopes, and can see some solar physical phenomena that were not visible in the past with optical telescopes, allowing us to master the changes in the solar radiation energy and the impact of these changes on the earth. However, since the diameter of our telescope is only 50 meters, its ability to receive weak signals is relatively weak and its resolution is not high, so it cannot be completely denied that the sun's brightness has dropped significantly, and it is not done by the "Dyson Ball" of the alien super civilization."

Wei Xinyu frowned and said nothing. Wang Lin continued:

"You can go to the Zhenxi Qingfeng Observatory, which is currently the largest rotating radio telescope in the Earth Star Kingdom. This radio telescope has a diameter of 500 meters and receives an area of ​​30 football fields. Its appearance is similar to that of satellite antennas. Compared with the 50-meter telescope of our Zhenbei Observation Station, its sensitivity is 20 times higher. The larger the telescope, the stronger the electromagnetic waves it collects. When you get information about the sun, you may be able to find the answers you need."

So, Wei Xinyu said goodbye to Stationmaster Wang Lin, took the special bus from the North Observatory Station and hurried towards the Zhenbei Airport.

Because it is quite long to get to the Qingfeng Observatory in Zhenxi, he still needs to take a long-distance bus from Qingfeng Airport, and there is only one bus every day. At this time, it was already past 9 o'clock in the evening, and there was no long-distance bus to Qingfeng Observatory. Wei Xinyu could only stay in Piaomiao City for one night. He took the long-distance bus to Qingfeng Observatory in the morning of the next day and rushed to Qingfeng Observatory.

The Zhenxi Qingfeng Observatory is located in a natural depression called Dawodang deep in Qingfeng Mountains. Its terrain is like a giant sinkhole. The three green mountains in Dawodang are isosceles triangles, and the depression in the middle of the triangle is where the fast’s big pot’ lands. The distance between each peak is about 500 meters, forming a natural pot rack, which steadily put the fast’s big pot on it and fills the entire valley. In order to maintain a unique electromagnetic wave environment, the Earth Star Astronomical Administration, at the beginning of the fast project research, planned a radio astronomy protection area with a radius of 150 kilometers with Dawodang as the center. It is strictly forbidden to set up any radio transmission equipment within a radius of 5 kilometers.

At 8 o'clock that night, after getting off the bus in Qingfeng Town, Wei Xinyu relied on the abundant energy in his body to walk on the rugged mountain road for less than an hour. There were only a dozen families in Dawotang, and they were in the depths of the mountains.

Sitting on the sofa at the office of Director Gaorui of Zhenxi Qingfeng Observatory, Director Gao Rui received him.

Master Gao Rui is not tall, very solid, with bronze skin, square face, thick eyebrows and big eyes, and full of breath when he spoke. He asked Wei Xinyu that after lunch, he made a cup of tea for him, then sat beside him, took out a pack of cigarettes from his pocket. After Wei Xinyu waved his hand and refused to smoke, he lit a cigarette alone, smoked a cigarette, and spit out a cigarette ring, asking:

"I received a call from Webmaster Wang Lin. You came to our observatory to find clues about Dyson's ball for aliens, right?"

"Yes." Wei Xinyu nodded without any concealment and replied.

Master Gao Rui took another puff of cigarette and said:

"Fast is both a radio observation center and a giant data processing center. All observed data will be filtered repeatedly by various algorithms. Through the observation data calculation, I judged that the sun is being wrapped by aliens, which is done by aliens' Dyson's sphere. First of all, we found that there were two major declines in the sun's light change curve. Once on the 190th day, it darkened by 15%. About 320th day, the light change curve fell by 22%. Before and after the second decline, there were many relatively small declines. Let me give an example to illustrate: a planet as big as Jupiter, at a suitable position, can only reduce the brightness of the sun by 1% at most. This abnormality aroused our interest."

Master Gao Rui opened the screen on the wall in front of the sofa, recalled relevant information, and continued:

"As shown in the figure: the vertical axis represents the brightness of the star (the brightness under "normal" conditions is 1), the horizontal axis is time, and the unit is day. Can't see clearly? Enlarge the vertical axis and see: Intercept two of the larger drops: I analyzed the possibility of an instrument error and believed that the observation error cannot explain this phenomenon, so the physical mechanism behind it must be considered. Usually, a large cloud of dust or dust disks around the sun will be considered first, such as the famous ε    aur. If the sun's brightness drop is caused by dust blocking, it is due to dust particles.

The temperature of the sub is relatively low, and the stars must be slightly brighter in the infrared band than normal. This phenomenon is called "infrared super", which is usually used to test whether there is a dust disk around the star. However, the objects blocking the sun do not have infrared super, which seems a bit strange. Therefore, I think from the perspective of civilization development, a civilization that has been advanced to the earth planet for thousands of years is possible to build a Dyson ball for energy purposes. I judge that someone is building a Dyson ball, and now this object has blocked some of our sunlight. I don’t know, do you agree with me?"

Wei Xinyu nodded in agreement and said, "Your analysis is correct."

Master Gao Rui said: "If this is true, it will be terrible. I have consulted some information about Dyson Ball. Some scientists believe that Dyson Ball is to surround a star, constantly absorb the energy of this star for its own use. This requires the development of human civilization to reach a second-level civilization to be able to achieve it. If Dyson Ball can be made, it means that this civilization is already very powerful. The development of a civilization cannot be separated from energy. The energy of the parent star is only the primary stage, and it is also a civilization below level one. At present, the Earth planet has not reached the first-level civilization. It takes about 10,000 years to go from first-level to second-level civilization, so it will take 10,000 years for humans to be able to build the Dyson Ball. Sooner or later, the energy on the Earth planet will be used up, so in the end, you have to go to the starry sky and the universe to mine energy from space. The most unabated thing in the universe is the star body."

Wei Xinyu corrected: "You are wrong. It's this Dyson Ball Plan. They have dismantled many astral bodies. What they lack is the ability to demolish the astral bodies. Now it has endangered the Earth planet. We are now trying to stop this crazy Dyson Ball Plan."

Master Gao Rui exclaimed: "They are crazy, you are even crazier. Just imagine what humans on Earth who are one level behind others will fight against them? You can only be insulted. We might as well cooperate with them to build Dyson Ball together."

Wei Xinyu took a sip of tea and said, "This is your wishful thinking. The other party builds Dyson balls not just to solve their energy problems. They want to kill two birds with one stone. They want to use Dyson balls to eliminate humans on Earth in one fell swoop."

Master Gao Rui cursed: "This plan is too vicious. Can higher civilizations develop together with lower civilizations? I have always believed that as long as humans enter the high-level intelligent creatures after entering the second-level civilization, they will never be as intrigue and follow the law of the forest like our current humans. I really didn't expect them to do something like Dyson Ball that would destroy humans and creatures in the solar system that would harm the law."

Wei Xinyu told Master Gao Rui: "What they pursue is the law of dark forests. When they built the Dyson Ball, they wanted to destroy the human civilization on Earth again. This is the result of the struggle between the two factions of the Heavenly Court."

Master Gao Rui sighed and said, "Hey, the universe is like a dark forest. For a certain high-level civilization, other civilizations are an eternal threat. The best way is to destroy the main star they rely on for their lives. No wonder, human disasters on Earth and planets have been constantly caused by them in recent years."

Wei Xinyu said: "So we have to fight. Although we are weak, we are not afraid. At least we can make them afraid."

...

The two were talking, but it was late at night. In order not to affect Master Gao Rui's rest, Wei Xinyu did not continue to talk. Master Gao Rui copied all the evidence of the Dyson ball detected by fast and handed it to Wei Xinyu on the U disk. Then he asked his assistant to arrange Wei Xinyu to stay at the Qingfeng Observatory Guesthouse.

The next day, Wei Xinyu bid farewell to Director Gao Rui, took a long-distance bus, then took a plane and other means of transportation, and finally returned to Mantes City. After waiting for a few days, Wei Xinyu finally met Chairman Wang Shouren who had returned from an out-of-town inspection in the office of the Chairman of the Earth Star League Building. He reported to Chairman Wang Shouren that the Zhenxi Qingfeng Observatory had detected that the construction of the Heaven Dyson Ball has indeed entered the final stage, and submitted his report on the discovery of the Heaven Dyson Ball construction, and initially proposed his combat plan for the Heaven Dyson Ball. In the report, he believed that because the power gap between the Earth Star Kingdom and the Heaven Dyson was too great, he could not attack strongly, so he could only take a clever lead. He first sent a micro robot to investigate. After finding out the opponent's background, he found the weak links of the Heaven Dyson Ball, and then sent troops to start from their weaknesses, take a sudden attack, and strive to destroy the Dyson Ball with one blow. A detailed combat plan is being planned.

Chairman Wang Shouren felt that time was tight and the Earth Star Kingdom had to act quickly. After receiving the order, the space troops of the Earth Star Kingdom sent a large number of micro robots to fly into space.
