I almost touched the moon

During dinner, Cheng Che thought about the light pollution problem that had troubled him for a long time, and asked Wen Song if he had any solution.

"It's very simple." Wen Song said while eating spareribs. "Just use radio telescopes, which can observe all day long, because they detect radio waves, rather than visible light. This problem is easy to solve. Just ask Cheng Xuan."

"What does he know? He just plays games at home every day and doesn't do his job properly." Cheng Che complained unhappily, "Wife, you've suffered."

Wen Song smiled and said, "Don't say that. He is a very smart child, otherwise he wouldn't have followed my words word for word. I waited for you at home for two or three hours today and you didn't come. I was wondering if he didn't tell you about my 'injury' or if you just didn't want to come."

"Why wouldn't I want to come? I was making soup for you at home, and when I came, there was no response when I rang the doorbell, and you didn't answer my calls, so I thought you didn't want to see me."

Cheng Che secretly felt lucky that he did not leave immediately and that Wen Song found him, otherwise they would have missed each other again.

He added: "So we only need to use a radio telescope to solve the problem of being unable to observe due to light pollution, right? It's so simple, but the people in our company's design department couldn't think of it. It's really too much."

"Fool, they need to consider economic benefits." Wen Song analyzed, "Since you want to combine the ski resort with the astronomical observatory, the purpose of this observatory is for commercial profit and entertainment, not research, so the people in your company's design department will definitely consider the cost and benefit issues.

Radio telescopes are very expensive, and you can't just build one alone. You need at least two telescopes to receive the same radio waves, so they are usually arrays. Even the most common medium-sized ones cost between several million and tens of millions of euros. If you really want to use it for astronomical observations, an array will cost at least 40 to 50 million euros. The initial investment is too high, and it's not necessary if it's just for commercial entertainment. "

After hearing her words, Cheng Che's doubts for many days were finally answered. It turned out that the problem was so simple, but he was stuck in the same place, focusing only on how to solve the light pollution and forgetting to find another way to solve it.

"It doesn't matter." Cheng Che said with a smile, "It doesn't matter if the initial investment is high. Anyway, my purpose is not for profit. This is a gift prepared for you."

Wen Song did not object, nor did he support him. He just said to him, "Why don't you directly sponsor me to develop the Kuiper Belt Probe? I applied for it when I was at ESA, but it was rejected by the top management on the grounds that it would cost too much money and the economic benefits would be too low."

"Okay." Cheng Che said immediately, "No matter how much it is, I will invest now."

"Let me do the math," Wen Song said in a serious tone. "The New Horizons probe NASA launched to Pluto cost about $8.7 million, with $6.5 million spent on initial R&D and construction, and $8000 million spent on launch. That was in 2006. Based on today's prices and the need to deeply explore trans-Neptunian objects, the cost should be around $15-20 billion. After all, our Venus probe cost more than 9 million euros in initial costs this time."

After hearing this, Cheng Che thought seriously for a moment, then said, "It's a bit expensive, but it doesn't matter, as long as you like it. And didn't you say that my beauty should be able to sell for a lot of money? If it's not enough, sister, please sell me to the Trisolarans."

Wen Song couldn't help laughing, he leaned forward and kissed him and said, "I can't bear to let you go, you are mine alone, if you dare to leave me again, I will really send your ashes and Aether to Venus."

Cheng Che quickly said, "I will never leave you again. If I dare to leave you again, I will send my ashes to Venus myself."

"I'm just kidding." Wen Song smiled faintly, his tone gentle, "I know I have a lot of problems in relationships. We broke up five years ago, and I never blamed you. So if in the future, you find that you don't love me anymore and want to break up with me, I will still respect your decision. But I probably can't bless you."

"No." Cheng Che said seriously, "Absolutely not. Songsong, you are really good. I was sensitive, naive and love-brained before, but you always tolerated me. I will change these things in the future, and I will never leave you."

"Yes." Wen Song looked at him and nodded solemnly. He walked forward and hugged him, leaning against his chest and said, "Ah Che, I love you, so can you stay here for me? I hope you stay. Of course, if you really want to return to China to live, I completely respect you and I won't interfere."

Cheng Che's heart trembled at her words. This was the first time she told him that she hoped he would stay with her. However, the ending was still very Iseylia's, she said she would respect his idea.

"I will definitely stay." Cheng Che smiled. "I originally wanted to return home because you didn't want me anymore. I wanted to stay away from you so I wouldn't bother you. But since my sister still loves me, I will definitely stay in Germany. And, little idiot, I still have to stay here to train."

Wen Song stood on tiptoe and kissed him deeply, saying vaguely but firmly: "A Che, I love you very much. I need you by my side."

Although they made love many times after their reunion, only on this night, when their bodies were closely connected, their souls seemed to have merged into one.

"A Che... A Che..." Wen Song called him again and again, holding his fingers tightly, and his nails inadvertently left a few red marks on his back.

"I'm here." Cheng Che leaned over to her ear and kissed her ear, "Songsong, I'm here, my wife..."

He saw the pendant on Wen Song's neck. It turned out to be the wedding ring he gave her. He couldn't help but lower his head, kissed the ring and her collarbone, and confessed softly: "I love you..."

This night was truly an all-nighter, and it was not until dawn that both of them were exhausted and ended the crazy night.

Cheng Che hugged her tightly, took off the pendant from Wen Song's neck, put the ring back on her left ring finger, and kissed Wen Song's brow tenderly, "Don't take it off again."

Wen Song was very sleepy, but his eyes were still half-closed and half-open, and he was not asleep. Looking at the rings on the two people's left ring fingers, he smiled and nodded gently.

"Baby, can I stay here tonight?" Cheng Che suddenly felt a little vengeful and asked her with a wicked smile.

Wen Song snorted and pinched his back, "Go away."

"I won't leave." Cheng Che held her in his arms, tucked her in, and said coquettishly, "I won't leave even if you beat me up. I haven't had you by my side for the past five years. I have insomnia every night and have to take sleeping pills to fall asleep."

"What an idiot..."

Wen Song looked at him with some distress. He was indeed thinner than five years ago. But she was also like this. Many nights she woke up from her sleep, looking at the empty bed beside her, her pillow soaked with tears.

"I won't let you go." Wen Song said lazily, burying his head in Cheng Che's arms, "Ah Che, I'm so sleepy, hug me."

The next day at noon, Cheng Che was awakened by the endless vibration of his cell phone. He turned around and saw Wen Song still sleeping soundly. Afraid of waking her up, he reluctantly got up from the bed and walked to the living room to answer the phone.

He looked at the dozen or so missed calls from Cheng Lixuan on his phone, and called back irritably, his tone also somewhat impatient: "What's the matter so early in the morning?"

"What do you mean so early in the morning?" Cheng Xuan was a little shocked. Cheng Che had a very regular schedule. He went to bed at 12 o'clock and got up at 9 o'clock every day. He never stayed in bed on weekends. But today he got up so late for the first time.

"Brother!! It's already 12:20! I have an exam at 1:00! Did you forget?"

"Oh, sorry, I forgot." Cheng Che yawned as he spoke, "You can drive there yourself."

Cheng Xuan was so upset that she thought her brother must have gone crazy. "Brother, I don't have a car or a German driver's license. Besides, your house is too remote and it's snowing, so I can't get a taxi. Your housekeeper isn't at home either, and I don't have the driver's phone number. Please come pick me up, please. I have an exam today on numerical methods in advanced astrophysics, it's Iseylia's class, and she's the invigilator. If I'm late, I'll be dead!"

"What? Iseylia is the invigilator?" Cheng Che suddenly felt that he was doomed, and immediately transferred some money to Cheng Xuan. He also sent him a number and said, "I just transferred some money to you. After the test, go buy a car and get a driver's license. I also gave you Uncle Jin's phone number. Contact him and ask him to pick you up. I have something to do now. I'm hanging up."

After hanging up the phone, Cheng Che hurried back to the room and woke Wen Song up: "Baby, wake up, get up quickly, you have an exam at one o'clock, did you forget?"

Wen Song woke up sleepily, yawned, and said in a daze: "What, what exam? I don't even need an exam."

After saying that, he fell down again and continued to sleep.

Cheng Che didn't know whether he should feel lucky for Cheng Xuan. If Wen Song was late, he wouldn't blame him. But he immediately picked her up from the bed and urged her, "You have to go to the exam! Isn't that your class?! Hurry up, honey, it's 12:40."

"Damn it!" Wen Song finally reacted and ran to the bathroom to wash up, complaining as he ran, "Cheng Che, why didn't you call me earlier!"

However, when he got up, he felt extremely sore all over, especially his lower body, which hurt whenever he walked. He glared at Cheng Che and said unhappily, "It's all your fault!"

"How can you blame me?" Cheng Che went to the closet to help her get clothes, and then brushed her teeth and washed her face with her, and said with a smile, "Wife, it was clearly you who asked me to do that this morning. Besides, I didn't know you were going to be the invigilator today..."

Wen Song also realized that he was in the wrong, and didn't say anything else, but just glared at him again. He casually put on a T-shirt and trousers, put on a baseball cap, picked up his jacket and bag and prepared to go out.

Cheng Che followed her, took her hand and said, "Sister's foot is not healed yet, it's best not to drive, I'll take you there. Don't worry, I'll memorize your class schedule and wake you up every day."
