The law of universal gravitation was born out of Kepler's three laws, and Kepler's three laws were not obtained through proof. It does not have a rigorous and complete proof process like other theories. It was born out of Kepler's analysis of previous stargazing data. Analysis and calculation. And those stargazing materials are, to put it bluntly, just star maps. This is the purpose of Yunyang asking these students to draw a star map every day. But things are different today. Because according to Yunyang's calculations, a lunar eclipse will occur today, and Shenghua City can just observe it. So today Yunyang and a group of students arrived outside Shenghua City after dark. A group of students surrounded Yunyang and kept asking various questions. The students were also chatting, laughing and having fun, which felt like an outing. After arriving at the place, a group of students took out pens and paper and began to draw the starry sky, while Yunyang sat down beside him. Today is another sunny day. There are stars in the sky and a moon hanging in the sky. It is very beautiful. The noise gradually calmed down, and Yunyang's heart gradually began to soothe. "I wonder if there are people in my original world who are observing this beautiful starry sky like me at this moment. If I disappear from that world out of thin air, a few people will think of me." Yun Yang felt a little sad in his heart. But this sadness disappeared immediately: "The past is like smoke, who would have thought that in this world, I would have such an opportunity again?" The lunar eclipse has begun. Although the Star Observation Pavilion is responsible for stargazing missions, their current astronomical knowledge does not allow them to predict the lunar eclipse very accurately. Therefore, many of these students saw the spectacle of a lunar eclipse for the first time. Countless exclamations sounded from the students, and Yunyang also had many emotions in his heart. "Hong Dou, have you seen a lunar eclipse before?" Yunyang turned to ask Hong Dou, who stood solemnly behind him like a statue. Hong Dou¡¯s face was expressionless, still tense, and ignored Yunyang. Yunyang coughed slightly awkwardly. The shadow of the earth gradually covered the moon, the moon began to become smaller and smaller, and the space between heaven and earth began to become dark. But precisely because of this darkness, the stars in the sky began to become brighter. Yunyang suddenly felt something strange. While Yunyang was concentrating on watching the starry sky, Yunyang felt that something seemed to have entered his body. This feeling is very strange, probably slightly similar to the feeling of attracting the spiritual power of the sun into your body. However, after these wonderful things entered your body, they did not disperse like the spiritual power of the sun. Instead, they stayed In his own body. Yunyang's heart moved, and he immediately moved his gaze away from the moon and towards a bright star in the sky. That is Vega, which is generally called Alpha Lyra in professional star charts. It is the fifth brightest star among all stars, but is the brightest star in the northern summer sky. Yunyang carefully observed this star with a light blue-white color, and the astronomical knowledge from his previous life began to slowly flow into Yunyang's mind. Yunyang could very clearly construct the position and movement pattern of Vega relative to the solar system in his mind, and he could also truly feel the distance between Vega and himself. Yunyang knows its distance from itself, its size, mass, star type, elemental composition, position, rotation speed, age, direction of movement, and all other data. There is an extremely clear star map in Yunyang's mind. In this star map, Yunyang can mark the position of Vega very accurately. In other words, Yunyang has now "positioned" Vega with the help of his astronomical knowledge. Yunyang observed Vega carefully. Sure enough, in Yunyang's feeling, the feeling that something seemed to have entered his body became stronger and stronger. At this moment, Yunyang felt that his body began to breathe. With every breath, some bluish-white indescribable substances entered his body, then slowly flowed through his body, and finally gathered somewhere in his body. A place, and then starting from this place, gradually spread to the whole body, and finally integrated into his own body and disappeared without a trace. Yunyang¡¯s heart suddenly shook. Although Yunyang cannot practice, he has heard the practice concepts pursued in Shenghua City countless times. At this moment, the feeling he feels is the same as the initial practice of practicing with the help of the sun's spiritual power described in those classics. The stages are generally the same! what does that mean? "Could it be that I can't attract the spiritual power of the sun into my body, but can I attract the energy of other stars? Could it be that my way out is not in the sun, but in the stars in the sky?" Yun Yang immediately began to get excited. Yunyang instantly?I thought of this question. Yunyang can be sure that in the history of Shenghua City, and even in all the history including the other eleven main cities, there has never been a precedent for attracting the energy of other stars into his body for cultivation. But From another aspect, if analyzed based on Yunyang's scientific literacy, there seems to be nothing surprising about such a thing. Because the sun's rays also carry heat, it is a very reasonable explanation to use the sun's energy to exercise oneself, and the other stars are also stars, and there is also energy in their light. So, since one can use the sun's energy to exercise oneself , why can¡¯t we use the energy of other stars to practice cultivation? I can¡¯t practice with the help of the sun¡¯s energy, so I¡¯ll use the energy of other stars to practice! This thought suddenly popped into Yunyang¡¯s mind. The feeling that something seemed to be entering his body continued, and Yunyang was 80% sure that he was really attracting the energy of Vega. However, there were two problems before Yunyang. First, there has never been any precedent for such a thing. If you practice in this way, no matter what problems you encounter, you will probably have to solve them yourself. Second, the remaining stars are too far away from the earth after all. The long distance means that less radiation energy reaches them, and their efficiency is tens of millions of times slower than that of the sun. But this is not a problem at all! Because this is a zero-to-one breakthrough, as long as he can practice, Yunyang will be 100% determined to solve it no matter what the difficulty is. "This feeling is really amazing" Yunyang sighed silently in his heart, "Practice, practice, train your body, and finally gain the power to travel through the stars with your physical body God allowed me to travel here, did it? Block all my ways out. " Yunyang is still immersed in this wonderful feeling, but as time goes by, this feeling is slowly slowing down. In the end, even if Yunyang can make it clear for Vega. With his positioning, Yunyang could no longer feel that wonderful energy. Yunyang looked away and saw that the lunar eclipse was over at this moment. Yunyang had a sudden realization in his heart: "Probably because the light reflected from the sun by the moon is blocked, reducing interference, I can feel the energy of Vega. Now that the lunar eclipse is over, I can't feel it anymore. But it doesn't matter. , I have many ways to deal with it If it doesn't work, just ask my senior brother to take me to practice outside the atmosphere. " "After you finish your lessons today, just leave. There is no need to explain to me." Yun. Yang walked over and gave a hasty instruction to a group of students, then hurried away with Hong Dou. Next to it was a low hill, and Yunyang planned to climb up to that hill to see if he could regain the experience he had just now. There is a very simple way to distinguish the magnitude of the radiation energy of a star. Simply put, the brighter the star, the stronger the radiation intensity. On the top of a hill, there is no doubt that many distractions can be removed and a better stargazing experience can be obtained. After being troubled for many days, he finally found a way to break through the current predicament, and Yunyang would not let it go easily no matter what. On the top of the hill, Yunyang once again concentrated on observing Vega. What made Yunyang feel a little relieved was that he finally felt the vague energy again. Although the feeling was very weak and intermittent, he could still feel it. Yunyang¡¯s face alternated between ecstasy and despair, and his expressions were constantly changing, as if he was going crazy. But Hong Dou was Hong Dou after all. No matter what weird moves Yunyang made, Hong Dou remained motionless without even a slight change in his expression. "Huh? There are so many stars in the sky, and Vega is not the only one that I can locate. What about the other stars? Can they also absorb energy from me?" Yunyang tried again with great interest. Time passed little by little, the moon gradually rose, and it was probably midnight. A man dressed as a soldier hesitated and climbed to the top of the hill, wandering not far away from Yunyang and not daring to get close. Yunyang glanced at him out of the corner of his eye and shouted: "What's the matter?" The soldier was relieved and approached Yunyang in small steps. He bent down in front of Yunyang and said respectfully: "Mr. Wu, I don¡¯t know when you will return to the city? The gate of Shenghua City has been reserved for you for a long time. We really can¡¯t delay it any longer.¡± Yunyang said casually, ¡°Then just close the door and wait for me to figure it out myself.¡± The soldier seemed to be in embarrassment. After hesitating for a while, he finally bent down and said, "So" At this moment, Hong Dou, who had been standing still like a wooden stake, suddenly opened his eyes. Like a small knife, it pierced the soldier. And at the same time that the soldier bent down, he turned his palm and there wasA dagger appeared in his palm, and with a flash of cold light, he stabbed Yunyang. At this moment, Yunyang was still observing the night sky with all his concentration, and was ecstatic about the vague feeling. ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª This is the first chapter today.
