Qin Wu and Song He were still talking, and they didn't seem to stop within a short period of time. "Thisthat's enough, let's talk about me and that Hong Dou." Yunyang lamented. "Well, that's fine." Qin Wu paused, seemed to organize her words, and then continued: "Sister Hong Dou is also a poor person. After entering the back of the academy, Sister Hong Dou was not accepted by the master. Instead, she entered the main courtyard of the academy to study. Sister Hong Dou is actually very talented. Her cultivation level is even higher than ours. She is almost at the seventh level of physical cultivation. " "Yes, Hong Dou. Although the senior sister is a bit grumpy, she has a good heart. No matter who asks her questions, she will answer them patiently. "Then why would she force me to marry?" Yun Yang asked hesitantly. Qin Wu sighed, "It's not you you are a little too playful and always get into trouble outside. In order to make your uncles and uncle Zhang less worried, Sister Hong Dou has been following you to prevent you from doing something like this again." Something bad happened. Well, you know, Sister Hongdou grew up with you and she also cared about you very much. When you lost a fight when you were a child, Sister Hongdou took you out to recover the situation. She loves to cause trouble, so Sister Hongdou always gets into fights. Perhaps Sister Hongdou¡¯s bad temper was developed at that time.¡± She always refused to listen, and even scolded Sister Hongdou for being nosy. Later, Sister Hongdou heard people say that after a man gets married, he will calm down and stop messing around, so, then" "So" "So Hong Dou is forcing me to marry him?" Yunyang asked incredulously. "It's not for your own good. Sister Hong Dou is so talented and beautiful. Many people in the college are pursuing Sister Hong Dou. If we don't really care about you and hope that you will take the right path, why would Sister Hong Dou sacrifice her life? Feeding the tiger" Qin Wu said, her eyes gradually became filled with a hint of hatred, but she immediately realized: "Ah, Master Yun, I'm sorry, I didn't mean that." "That's all, that's all. ." Yunyang waved his hand, stood up unsteadily, and walked to the inner room. Yunyang felt that he was burdened with another debt, and he even began to lament in his heart: "You, how many people and debts do you owe When will I be able to pay off so many debts?" " Outside, Qin Wu and Song He were still talking in a low voice: "Xiao Wu, are you saying these things a little too harshly?" "But what I said is true" "Okay, although. It's all true, but I don't know if Master Yun can listen to it. " "Don't you notice? After Master Yun lost his memory, he really seemed to be a different person. He seemed to be much more dignified and knowledgeable. The thing can even take us out of danger and stop touching me Let me put it more seriously, maybe Master Yun can really change his mind. " "But I hope Master Yun wakes up. After coming here, things really changed a lot" The words gradually became smaller and smaller, and eventually they could no longer be heard. Yunyang was lying on the bed, feeling very sad in his heart. All kinds of thoughts were entangled and he couldn't figure it out clearly. In the end, it just turned into a long sigh, "Alas" Yunyang's injuries still have not fully recovered, and there is nothing going on at this moment. Yunyang thought for a while and then fell asleep. I don¡¯t know how long it took when I woke up. Anyway, it was daytime outside again, and the sunlight without clouds shone directly into the Taiyu Golden Pagoda, seeming to coat everything inside with a layer of white light. Zhang Yue has woken up. Although he is still a little weak, according to him, there is no problem in making the Jiuxuan Lingshi. Yunyang also saw some finished Jiuxuan Lingshi products next to him. The Jiuxuan Lingshi does not look like a stone, but looks like eggs with a soft brilliance on it. However, the brilliance emitted by these Jiuxuan Lingshi created by Zhang Yue is not pure. "How many Nine-Xuan Lingshi will be consumed to get from Venus to the Ancestral Star? Brother Zhang Yue, how long will it take you to complete the production?" Yun Yang asked. "Coupled with the reserves of Jiuxuan Lingshi needed to maintain our survival, I will need to work here for about a month. Then, after leaving Chang Geng and returning to the ancestral star, I will continue to use the spiritual power of the sun to create Jiuxuan Lingshi, and will It will allow us to return to the ancestral star." Zhang Yue thought for a moment before replying, "However, my previous repairs to the Taiyu Golden Pagoda were not complete. With my cultivation, there is really no way to repair the Taiyu Golden Pagoda. Absolutely, well, the Taiyu Golden Tower can still last for about four months, which is enough for us to return to the ancestral planet. " Yunyang¡¯s heart tightened. After coming to this world, Yunyang has become accustomed to questioning the ideas and conclusions that Zhang Yue, Qin Wu, Song He and others took for granted. Because there is much about interstellar navigation that is counter-intuitive. Yunyang didn't think clearly about what was wrong at the moment, but as if it was a conditioned reflex, Yunyang became suspicious of Zhang Yue's statement that "four months is enough to return to the ancestral star". "First tell me, during the process of landing in Chang Geng, how did you determine the trajectory and position yourself and the target?" Yun Yang looked at Zhang Yue closely. Regarding this question, Zhang Yue was a little confused, but Qin Wu was the first to answer: "Do we need to be sure? We just look at the Chang Geng star in the sky, and then fly straight towards it. If we find that the direction is off, we can correct it at any time. As long as we keep heading towards If we fly with it, we still can't reach it?" Yunyang touched his nose and continued to ask in a calm tone: "Then, you should have the following data, how far we have traveled from Zuxing to Changgeng? "How much time did it take?" "This" Qin Wu and Song He looked at each other and replied, "It took about 83 million kilometers and a little more than two months." Interjected: "Now the Taiyu Golden Pagoda can support four months. Isn't this time enough for us to return to the ancestral planet? Is there anything wrong?" Yunyang exhaled softly and slowly closed the door. Eye. Yunyang is making intense calculations in his brain, calculating the distance between Venus and the Earth at this moment. The difference between the orbit of Venus and the orbit of the Earth is only about 50 million kilometers, but this is the orbital gap, and this number is also the theoretical closest distance between the two planets. But it is obvious that the Earth and Venus are constantly moving, and the distance between them is constantly changing. It has been nearly three months since we left the earth. How much will the distance between the two planets change during this time? Yunyang quickly calculated the result. The conclusion is that the distance between the Earth and Venus at this moment is about 90 million kilometers. But 90 million kilometers is a straight-line distance, and in real interstellar navigation, it is obviously impossible to travel in a straight line. The straight-line distance is 90 million kilometers. Real navigation, even according to the shortest route, requires sailing more than 110 million kilometers. Through the data provided by Qin Wu before, Yunyang can calculate the average speed of the Taiyu Golden Tower, which is about fifteen kilometers per second. At this rate, the time it would take to return from Venus to Earth would be less than three months. However, taking the shortest route will consume much more fuel, which means that Zhang Yue needs more time to store the Nine Mysterious Spiritual Stones in the orbit of Venus, so the total time will add up to almost five months. Also, during the voyage, the earth is also moving, and the distance from Venus will continue to increase, which will consume more time. ¡°And¡ the Taiyu Golden Pagoda can only support four months. In other words, before reaching the earth, the Taiyu Golden Tower will not be able to support it, and all four people, including Yunyang, will die in this vast space. Yunyang suddenly opened his eyes. "This won't work." Yunyang said, "We can't go back because we don't have enough time. Four months is not enough." "Why?" Qin Wu asked with a hint of surprise. "Because, because" Yunyang grabbed a piece of paper and drew a small circle on it, "This is the sun." Then, Yunyang clicked two points at different distances outside the small circle, " This is the ancestral star, this is Venus. " "Both the ancestral star and Venus are orbiting the sun. They are not fixed. In other words, the distance between the ancestral star and Venus is also changing. We spend two It takes many months to travel from the Ancestral Star to Venus, but it will take at least five months for us to return from Venus to the Ancestral Star! " "Are the Ancestral Stars and Chang Geng both revolving around the sun? This, this isn't it true that both the Sun and Chang Geng are orbiting the sun? Are you orbiting the ancestral star" Qin Wu murmured. Zhang Yue¡¯s expression suddenly changed. "Yes, yes, that's it, that's it" Zhang Yue suddenly seemed very tired, "In the process of leaving the ancestral star and coming to Chang Geng, I looked at the stars for a long time. In the past, I also heard Master say a lot. At that time, I had a vague feeling that the starry sky movement as we currently understand it seemed wrong, but I couldn¡¯t tell what was wrong. Now Junior Brother Yun said that Zu Xing and Chang Geng They are all revolving around the sun That's right, that's right, that's it. " "Think about it carefully and think about everything you have seen along the way." Zhang Yue said to Qin Wu and Song He. said. Qin Wu and Song He are naturally outstanding figures if they have the qualifications to explore Chang Geng. Now, ?After receiving Yunyang's prompt, the two of them thought carefully for a moment, and suddenly their expressions changed. "It's trueit's truethe distance between Zuxing and Chang Geng keeps changing. We, wecan't go back."
