The two nodded, agreeing with the conclusion. Not only Mr. Zhang shook his head at this conclusion, but even science fiction writer Kang Buming shook his head, "One-tenth of the speed of light is too high, and human technology in a few hundred years will definitely not reach this level." However, perhaps because he did not want to cause excessive pessimism, he immediately changed his tune and said, "No, no, I am afraid that I would go too far when I said, 'I will definitely not be able to achieve it.'" Many inventions in the history of science and technology are sudden and unconventional, for example, no scientist predicted the computer, but it appeared suddenly, and its development is faster than expected. Therefore, it is not impossible that some kind of completely new spaceship propulsion technology will emerge in this hundred years. ”

Chu Tianle continued his train of thought, "Moreover, the above estimate has not taken into account other negative factors, including: Will the cataclysmic area be expanded? It is likely to be expanded, but it has not yet been confirmed by observations. And even—at the junction of the original 'moderate expansion' and the new 'sharp contraction', will there be a tear, tearing out a closed river of weak water that cannot be crossed, and enclosing humanity in it? You may think that the vacuum doesn't matter if it's torn. But the vacuum is not empty, it must have a deep structure, otherwise it would not be able to bend due to gravity, and it would not be possible to produce quantum fluctuations. "Please note that this abrupt change from mild expansion to violent contraction has never occurred in the 13.7 billion years of the universe — perhaps it is too much, so it will be changed to: at least humanity has never experienced it." This phenomenon is completely new, and we cannot just take it for granted. He paused for a moment as usual, allowing his godfather to make the necessary translation of his fuzzy accent, "In a word, this sudden local collapse is too evil, and until the cause of it is known, it is impossible to predict in which direction and to what extent the crack it caused will expand - but Mr. Zhan is right just now, the situation is very urgent, we can't sit and wait for death, we can only grope as we go." This is a dilemma. ”

This conclusion has cut off almost all hope. The atmosphere in the room was even more suffocating. After being silent for a long time, seeing that no one spoke, Chu Tianle smiled and said:

"Just now Mr. Kang said that our universe has a terminal illness, in fact, I have been terminally ill since I was five years old, and I spent my childhood in the torment of fear. Later, thanks to my godfather," he looked at Ma Shiqi next to him, "when I was seven years old, he decisively told me the truth, cut off my back road, and gave me the courage to live." The Art of War: Death and Resurrection. What kind of courage can humanity burst out when it is put in a desperate situation? Maybe it can make the impossible possible. So, the estimates we just made may be too pessimistic. ”

The atmosphere of the venue was slightly relaxed, and people all smiled and signaled to Chu Tianle. They weren't convinced by Chu's comfort, but at least the brave boy sent a small warm current to everyone's hearts. Yu Leshui next to her happily took his arm, and now she was really impressed by this big boy who was three years younger than herself.

Since then, the free speech phase has been largely cold. Today's participants are all first-class scientists or technologists, but they are all cautious people who don't say something inconsequential in the myriad of situations in their hearts. The catastrophe was so sudden, that the calm river of civilization had suddenly fallen into a waterfall, and that the conventional experience was now invalid, leaving the minds of wise scientists at a loss. It has always been said that science can transform nature, but by "nature" we mean "local environment". No one has ever dared to say that science can transform the entire universe. For the universe, human beings are still, and probably will always be, a swarm of ants. Yu Leshui noticed that He Lao was also secretly locked on his eyebrows. This minister has always been adept at handling various incidents, but those events are human internal wrestling, and now human beings are wrestling with God, and the two are not comparable. If you want to make decisions now, you don't rely on life experience, but on scientific intuition, and He Lao is not good at this. In comparison, the most confident people in the venue were Chu Ma and the others, who faintly became the center of the venue. This is because of a special reason - they made the discovery five years ago, so they have five more years of thinking time and five more years of mental preparation than others. Yu Leshui was particularly surprised by Chu Tianle, a big boy. Judging from what he just said, there is no doubt that his knowledge, vision, personal cultivation, mentality, and professional attainments in astronomy have reached a very high level. As the saying goes, "there is poetry and books in his belly", his belly must be full of books, not literary books but scientific books, and these inner knowledge are the support of his external bearing. Inside his sick and crooked body, the flame of genius burned brightly, and you could feel its burning heat just by the side.

She couldn't help but think back to the terminally ill boy who was cold and autistic fifteen years ago. How did he accomplish such a drastic transformation in his fifteen years of life in the mountains? Yu Leshui suddenly had a strong desire to get to know him deeply and closely, and to write an interview. As for this "big" bad news - whatever, even if it comes tomorrow morning, Yu Leshui will not commit suicide tonight, she will grit her teeth and stand up until that moment comes. In this case, you might as well open your mind and do a few things according to your wishes, anyway, other worldly affairs, such as work, future, marriage, and even a woman's beauty, have become dispensable. The trees are about to fall, and they can't take care of these beautiful eggs. Yes, so decided. She came out of her reverie and heard He Lao saying:

"Hey, guys in the back row, today you only have ears and no mouths, but do you want to choose a representative to say a word or two?" The people in the back row looked at each other, and no one took the initiative to speak. He Lao named and said, "Xiaolin, say it." He introduced to everyone, "His name is Lin Bingzhang, the chief thinker of the National Development and Reform Commission. ”

Lin Bingzhang, who is in his early forties, stood up from the back row. Obviously, this is also a cautious person, and after thinking for a while, he said carefully: "I am afraid that it is difficult for the general public to believe that a small blue shift on the spectrograph means a cataclysm." But a devout person of science would believe it. The crowd nodded silently, but he then changed his tone, "But—the pious are prone to lose objectivity. ”

Although this sentence is a euphemism, it is actually a serious doubt about the prophecy of the cataclysm. Zhan, Xu, Ma, and Chu looked at each other, obviously disagreeing with his last sentence. Zhan Xiang sighed:

"We also hope that this is a lie, but the spectrograph has no faith and will not lose its objectivity."

Although the atmosphere in the venue has been very sluggish, this sentence still makes everyone smile. Lin Bingzhang himself smiled generously and sat down. He Lao made a final summary:

"Today was supposed to be a retreat, and I didn't want a clear result, so let's open it here. I would like to ask you to think carefully about what you will be attending at the top of the next meeting, and I hope that you will be able to give some practical advice at that time. Kobayashi's brief speech just now is very valuable, and it includes two points: 1. Is this catastrophe of partial cosmic collapse completely real? 2. If it is true, how to convince the general public, including policymakers, to believe it? These two points need to be done carefully. In addition, I would like to ask Xiao Zhan and Xiao Xu to continue to negotiate with the observatories around the world and strive to postpone the announcement date as much as possible, even if it is worth one more day. Zhan Xiang wanted to say something, He Lao guessed what he meant, and preemptively said, "Of course, delaying it for too long may also cause unofficial leaks, which is even more disadvantageous, you can weigh it yourself at this point in time." You will also have to consult with the observatories to draw up a press release in advance, and my opinion is that the catastrophic changes should be watered down as much as possible in the press release. This is not a cover-up, but a responsibility to society. You might as well rub in what Mr. Kang and Xiao Chu just said. I agree with them on this point, I just don't believe it, all of a sudden humanity is at a dead end, there is no way to think about it, God won't fuck it like this! Also, be careful to keep it secret before posting, especially you, the fish reporter who barged in halfway. ”

Yu Leshui said dryly: "Don't worry, Elder He, I will seal my mouth tightly." ”

"Mr. Ma and Xiao Chu, will you go home after the meeting? I'll arrange for a helicopter to take you there. ”

"Let's take a walk around the street and come back in the evening," Ma said. ”

Yu Leshui immediately said: "Uncle Ma, Tianle, I want to go to your house too!" Uncle Ma and Xiao Chu both nodded happily, and Yu Leshui happily took their arms. Her happiness inevitably seemed "heartless" in the current atmosphere, He Lao subconsciously shook his head and said sullenly:

"I'm going to go back to Beijing and report to my superiors. Well, I really don't want to give them this result. Meeting! ”

5

It was difficult for Chu Ma and the two to get out of the mountain, and they did some private things in the afternoon: haircuts, shopping, and shopping. Yu Leshui entrusted the car to the farmhouse hotel for safekeeping, and accompanied the two of them around the market town. In the evening, they took large bags and small bags, including gifts from He Lao, and took a helicopter to Ma's house. The pilot was a baby-faced soldier surnamed Zhu, and there were two armed police escorts on board. The setting sun is already level with the top of the mountain, and the glow reflects the green of the mountain. There is a characteristic of Baotianman's mountain, although the cliff is steep and deep, the top of the mountain is flat. The helicopter landed on the top of the mountain, and the armed police helped the two disabled people down. Yu Leshui jumped out of the helicopter and was fascinated by the mountain scenery at sunset. The clear stream and waterfall, the sound of pine waves, the clear air, and the huge trees hugging thick everywhere. I really didn't expect that in the heart of China, after thousands of years of development by the Chinese nation, there is still a pocket-sized primeval forest area here. The armed police sent the two back to their residences, and Yu Leshui followed behind, dialed the arrows and bamboos beside the road, pulled the dogwood on the rock, and went to the clear spring to drink saliva, and frolicked with the red-bellied golden pheasant and tiger phoenix butterfly, which was quite self-satisfied. The vitality of nature seeped into her heart, and most of the gloom in her heart dissipated.

Xiao Chu's illness was already quite serious, and Yu Leshui at the venue didn't notice it, but after walking on the mountain road for a while, he was obviously unable to support it. The armed police squatted down to carry him, he excused himself in every possible way, and Ma Bobo said softly:

"Lele, let the armed police comrades carry you."

Chu Tianle no longer insisted, and leaned on the back of the armed police. Yu Leshui's heart sank, and he couldn't help but think of the scene when Xiao Tianle insisted on not wanting his mother to carry him fifteen years ago. With his character, he will not let the armed police carry it unless it is absolutely necessary. It seems that he is terminally ill and that time is running out for him.

When she was about to arrive at Ma's house, she saw a white building on the top of a hill not far away, with a spherical roof and a double lobe at the top. Dad said that Uncle Ma used to study astronomy, and later engaged in industry, with assets of more than 100 million. Unfortunately, at the peak of his life, he suffered a car accident, his wife and daughter died, and he lost his left leg, which was traumatized. Later, Uncle Ma handed over the company to someone else to take care of it, and came to the mountains to live in seclusion, regaining his love for astronomy in his youth. Because there is no light pollution in the mountains, it is easy to observe the stars. But Yu Leshui never knew that Uncle Ma had built a small private observatory here! No wonder the two of them made that discovery.

Tianle's mother Ren Dongmei greeted her at the gate of the hospital. Yu Leshui saw from afar that she was pregnant, and she should be more than five months old. When she got closer, she didn't recognize Tianle's mother anymore. When they met the mother and son fifteen years ago, Tianle's mother was haggard and aging, like an old woman in her fifties; And now she was black and red, and her body was strong, as if she were not yet forty years old. She ran over briskly, first held Yu Leshui's hands, and hurriedly asked her parents how they were doing; then took his son from the back of the armed police and settled him on the chaise longue; He was busy serving tea and pouring water for the guests. The two soldiers didn't stop long, and returned after a few sips of water. Tianle's mother thanked them again and again, and went out to see them off.

Yu Leshui also went out. She was a little secretly curious about Tianle's mother's pregnancy and her relationship with Uncle Ma, and wanted to avoid the two men's side inquiries. But there was no need for her to listen "sideways". Sending the armed police away, Tianle's mother noticed her gaze, and was a little embarrassed, but then she made her words clear very quickly:

"Miss Leshui, will you laugh at me? I'm almost fifty years old, and I still have a big belly. Besides, there is no name between me and Mr. Ma. We also want to get a marriage certificate, but Tianle has no news from his father, and he needs to go to the court to dissolve the marriage, and the procedures are very troublesome. I had to take care of two disabled people, and it was difficult to get down the mountain, so I dragged it down...... In my opinion, it doesn't matter if you have a name or not. I have been fascinated for the past two years, I don't want to give birth to a baby for Mr. Ma, you know that he has no children and no daughters, his only daughter went with her mother in that car accident, I have to leave him a blood in the world. He is sixty years old this year, and it will be too late if he doesn't have children. You said that since Pangu opened the world, Nuwa Niangniang created people, isn't everyone living to stay behind? ”

Yu Leshui couldn't stop laughing when he heard it. This woman with little culture looks at life in this way, and her mind is really simple. But if you think about it, her words actually distill the essence of life. Biologists say that the nature of living things is actually eight words: to preserve oneself and to continue for future generations. The "alive" and "posthumous" she just said are the colloquialism of these eight-character heavenly strips, and they are the most concise and incisive expressions. She remembered that when she came here with her father fifteen years ago, he had introduced this area as the birthplace of Pangu mythology [Note 3], and these Chinese myths had infiltrated with the blood river of the Chinese nation. It is a dark river that flows under the surface of society, usually unnoticed by people, but it is incomparably powerful and incomparably long-lasting, and fancy things such as mortal law, politics, and fashion cannot shake its foundation at all. Tianle's mother went on to say:

"I said that I wanted to give him a baby, and Mr. Ma was happy to do so...... Leshui, what are you laughing at? Laugh at me for not being rude? ”

Yu Leshui laughed, "Where, where." I'm glad to hear you. Auntie, you underestimate me, how could I be so conservative and rigid. I think it's a very romantic thing to be able to have a child for the man I love, and I don't care about the name or anything. Auntie, I admire you so much. You go on to say. ”

Tianle's mother was very happy, "Tianle also repeatedly persuaded me to have one, and he said that after he left, someone had to accompany me and his godfather." He said that, and I finally made up my mind. ”

Yu Leshui's heart was shocked. Quickly glanced at Tianle's mother, and her eyes were very calm at the moment. This was the first time she had heard Tianle's mother talk about Tianle's death in a calm tone. The calmness shocked her, but she got used to it. Tianle's mother is the best mother in the world, burning a lifetime of love for her son. But for more than ten years, she has been grinding with the ears and temples of the "Grim Reaper", and has regarded it as an ordinary member of the family, and life and death are so "homely" and seamless. Looking at Tianle Ma, Yu Leshui couldn't help but have an association, she felt that this woman was like an old oak tree in the mountains, the tree was not high, the crown was not big, it was far from being beautiful and beautiful, but it was rooted in the stone crevices, and its vitality was extremely tenacious. She had just mentioned death, and Yu Leshui couldn't help but think of Chu Ma's discovery, and asked tentatively:

"Auntie, the two of you went out for a day's meeting, do you know what it is?"

Tianle's mother said nonchalantly: "I know." What did Chuma find out, to put it bluntly, that the sky was about to fall. ”

"Then you ......"

"I didn't put this at ease. It's not that I don't believe in the two masters, they are both literary and opera stars, and they are too smart to say, even the country invited them to give lectures, and this matter must not be fake. The ancients said that there is a catastrophe in 500 years, and this is a catastrophe, so that our generation can catch up. But the calamity has started and ended, just like Nuwa Niangniang at that time, half of the sky has collapsed, isn't it? Make up for the heavens, people still have to live, God will not be so conscienceless and block all roads. Besides, even if the sky really falls after 500 years, it will not delay me from giving birth to the baby in my belly. Children beget grandchildren, grandchildren beget children, 500 years is enough for 20 generations...... Leshui, what are you laughing at? ”

Yu Leshui couldn't help laughing out loud, and the gloom in his chest all dissipated in the laughter, "Nothing, nothing." Auntie, I just feel happy to hear you. Auntie, I'll have to stay here a few more days and listen to you more. Auntie, are you welcome? ”

Tianle's mother was happy, "Then you still need to say?" I've been looking forward to meeting the Yu family for a long time, and you are my great benefactor. ”

Uncle Ma's mountain residence is simply a place for cultivating immortals. Outside the courtyard are towering trees, birds chirping, and squirrels poking their heads through the branches. The bamboo fence in the backyard faces a cliff, and the mountain wind rolls up from the valley, sending gusts of pine waves. On the east side of the courtyard is a stone wall, and there is a mountain spring in the crack in the stone, which flows through the courtyard and flows into a pool of water on the ground, which is supposed to be the source of water for the home. The sky is blue and transparent, and the air is very fresh. The furnishings in the home are quite simple, but the study is a circle of wall-filled bookcases, piled with all kinds of books, especially in the fields of astronomy and physics, which makes the "fairy wind" of the mountain residence add a scientific "Tao bone". In such a fairyland, especially with a cheerful person like Aunt Ren, that gloomy prospect is at least temporarily away.

Chu Tianle leaned on the recliner to take a nap, and Uncle Ma was already taking care of dinner. Tianle's mother hurriedly pushed him to rest, took over the cooking by herself, and Yu Leshui also went to help her. Although it is far from the world, it has its own power supply and all the appliances in the kitchen. The two quickly made a table of game, including rock cabbage, Diqulian'er, wild leeks, etc., and the four of them had a lively dinner. After the meal, Yu Leshui's mobile phone may have just been unblocked, showing a lot of text messages and missed calls at once. She quickly replied briefly. There were two text messages from two men with whom she was having an affair and wanted to ask her out for the weekend. She declined, now is not the time to fall in love. The reply to her parents was very vague, because she was not good at revealing that she was currently here with Uncle Ma, so she only said that she was too busy in the past two days and would talk back in a few days. The newspaper was asking her about the progress of the interview, apparently not receiving the text message she sent last time, and her reply was very simple:

"I'm covering a new big story in the mountains, don't contact me for ten days."

Then it simply shut down. She thought that Sister He of the social department of the newspaper company, maybe she would add the editor-in-chief, she must have stared at this leave of absence for the first cut and then the play, maybe she would be furious. But with her current state of mind, the constraints and rules of the world are really downplayed.

There are only two bedrooms in this mountain house, and the enthusiastic Aunt Ren wants to vacate the master bedroom for her, but Yu Leshui resolutely refuses. So, they added a movable bed to the living room. Uncle Ma said:

"Shui'er, you should rest early, I should go into the cage." He explained with a smile, "Referring to the telescope's main focus cage." Over the years, as long as it is sunny, Tianle and I have never missed observations. He looked at Yoshiko and said, "But I've been alone for more than a year." The three of us in my family have a new division of labor, your aunt mainly uses her hands, I mainly use my eyes, and Tianle mainly uses my brain. ”

In other words, Chu Tianle's body no longer allowed him to "enter the cage". Yu Leshui immediately said:

"Uncle, I'll go too!"

Uncle Ma hesitated a little, "You're going too?" It's hard to walk at night. The main thing is that there are not two people in that cage, and I have to observe all night, and no one accompanies you. ”

"It's okay, I'll wait at the bottom of the cage alone." Yu Leshui laughed, "I'm sorry, I'm a bit of a fetishistic fanatic. You two have made a great discovery, and I want to touch your divination tools with my own hands. ”

Chu Tianle suddenly said, "I'll go too, I'll accompany Sister Yu below." Seeing that the two old men were a little hesitant, he said indifferently, "It's okay, I can go up, it's just a little slower." Godfather, you go first, don't wait for me. ”

Without waiting for the two old men to speak, Yu Leshui immediately said: "Of course it is best if you can go Tianle!" Don't worry about walking, I'll carry you. Don't be surprised, aunt and uncle, I can do it. At school, I loved sports, and I was able to climb rocks and mountains. I climbed a big persimmon tree outside the hotel in the early hours of this morning to investigate, but I was caught in plainclothes, or I wouldn't have been able to enter the venue. ”

She exposed her family ugliness so much, which made Uncle Ma laugh, "That's the case, no wonder He Lao said that you climbed a tree and jumped in, it turns out that there is indeed such a thing." ”

Chu Tianle didn't want a girl to carry himself, so he shook his hand vigorously, saying that he was not going. But Yu Leshui didn't care, and forced him to pull him up from the recliner and carry him on his back. She felt a little sad on her back, and she could feel the skinny bones on her back. Tianle is not tall, about 1.65 meters, and his weight is even lighter than the weight that this height should have. She joked:

"Hey, so light! I carry you like Sun Dasheng carrying a red child, no need to work hard. Let's go. ”

Uncle Ma no longer dissuaded, and said briskly: "Okay, let's go." Dongmei, you're home alone tonight. ”

This mountain road is indeed not easy to walk, but fortunately, it is not long, and Yu Leshui took a break in the middle and arrived. Uncle Ma took Tianle from her back, placed him in a chair, and turned on the light switch. Yu Leshui gasped and looked around at the furnishings in the house. Under the spherical dome is mainly an astronomical telescope, which is a very old piece of equipment, stupid and stupid, black and not slippery, and even equipped with an old-fashioned copper double knife electrical switch, a relic of the last century. Its main focus cage is equally worn-out and wobbly when it ascends. Uncle Ma opened the roof, pointed the tube at the night sky, and turned the roof to adjust the direction. He asked Tianle to stay below, and led Yu Leshui to climb to the observation platform to visit. He said that this is a 36-inch Newtonian reflecting telescope, which was eliminated by an observatory in the United States. It's old and a bit of a dysfunctional, but overall it works. "It's a luxury for an amateur astronomer to have a telescope like this." A Newtonian telescope uses a large concave mirror at the bottom to focus the starlight and reflect it onto a small mirror suspended over the head, which then directs the focused light from the side to the eyepiece, camera, spectrometer or spectrograph. The observer must be in mid-air to adjust the focal length.

He also introduced several other devices, such as stellar spectrographs, CCD photocouplers, computers, etc., which are all of the latest in the world. After a general introduction, he returned to the focus cage, turned off the lights, and began to observe. Yu Leshui groped his way to Chu Tianle's side and sat down next to him. For a moment neither of them spoke, staring at the stars in the dark sky through the trough viewing window on the roof. Today is a moonless night, there is not a single light in the field of vision, the night sky is dark and quiet, so quiet that you can hear the oscillation of the stars and the whispering of the stars. Two pairs of eyes burned and glowed in the darkness. Chu Tianle was afraid of affecting the observers, so he lowered his voice and said with a smile:

"Sister Yu, you have already touched the magic weapon used for divination, are you a little disappointed? An old piece of scrapped equipment has no mystery at all. ”

Yu Leshui also lowered his voice and said, "On the contrary, I feel very awe. I always had a hard time believing that it was possible to pry open the secrets of the universe with these man-made, hard-nosed things. ”

"The ultimate secret of the universe must be the easiest. In these years of study, I have a strong feeling that scientists are always innocent, and cosmologists are the most naïve among them, and what they want to do is to use childlike simple and intuitive imagination to solve the ultimate secret of the universe. ”

"Like a kid blowing bubbles?"

Chu Tianle keenly guessed what she was referring to, and said with a smile: "Yes, just like when I blew bubbles." ”

Leaving the gloomy atmosphere of the conference room and coming to Ma's house, Yu Leshui's mood was much more cheerful, but the devil couldn't avoid it anyway. She sighed: "Tianle, is that disaster really inevitable? Just now I heard Aunt Ren say something, which coincided with He Lao's words, she said: God will not be so unconscientious. ”

She thought that Chu Tianle had made an optimistic statement at the meeting, so she should agree with this. Unexpectedly, Chu Tianle shook his head and simply denied this sentence, "No, such optimism is meaningless. God doesn't deliberately do evil, nor does he deliberately not do evil, he only acts according to his own rules, and does not consider the meaning of these rules for life. Throughout the entire history of biology, 99.9 percent of species have been extinct, so in terms of objective effect, God has mostly done evil. ”

Yu Leshui approached him as if he was afraid of the cold, and complained: "You are so cold and ruthless, you are reluctant to say even a word of relief." So, your optimism at the end of the meeting was fake, right? ”

"No, that's not optimism, it's contemplation. No matter how hopeless the situation is, I will try to survive and do my best to obey God's destiny. After all," he said calmly, "that's how I've come over all these years." ”

Yu Leshui has known that patients with muscular dystrophy usually die between the ages of 20 and 30. Tianle is twenty-two years old this year, so the rest of his life is really short. Just now, Tianle's mother mentioned her son's death in a normal tone, but Yu Leshui couldn't do this. She didn't want empty words to comfort her, it was useless for Chu Tianle. After thinking about it, she said sincerely:

"Either way, your life is full."

Chu Leshui smiled: "You are right. This is thanks to my mother, godfather, and your whole family for their help fifteen years ago. The fate of our mother and son changed on that day. Sister Yu, I have always wanted to have an opportunity to express my gratitude in person. ”

Yu Leshui waved his hand, those things are not worth mentioning. She said, "Talk about you, about the fifteen years since you entered the mountain." No, from the time you were born. What a rare opportunity to have an in-depth interview with tomorrow's world celebrities, and when Chuma finds out about it, the interview will be published at the same time, and I, an intern journalist, are sure to be an instant hit. She laughed and laughed at herself, "The sky is about to fall, isn't it ridiculous to care about earthly names at this time?" Ridiculous or not, you better fulfill me. ”

Chu Tianle also smiled and quipped: "Is it a little early to interview my life?" I originally wanted to live to be 100 years old and then write a memoir, and the name is ready, "A Hundred Years of Collecting Shellfish". You've advanced this by a full seventy-eight years. ”

Both of them laughed, Yu Leshui put away the banter, and said solemnly: "Tianle, I'm serious." I want to show the public how a terminally ill person can live tenaciously and live a fulfilling life. When the news of the universe's terminal illness is made public, society will inevitably fall into panic, and at that time, this article should have a bit of a positive motivational effect. ”

Chu Tianle did not answer immediately. There was a squeak overhead, it was Uncle Ma who was manually adjusting the rotation of the roof, and the telescope was equipped with a rotor clock that was not very useful. Then there was a slight sound overhead, it was Uncle Ma fine-tuning the tube to correct the error in the operation of the base. The adjustment was over, and Uncle Ma was transformed into a black sculpture again, motionless in the trough-shaped canopy.

"Okay, let's talk about it then. In fact, to be honest, it's not too early for me to sort out my life now, just two or three years in advance. ”

He calmly said this sentence with sadness in it, but it made Yu Leshui's heart hurt like tears. She gently held Chu Tianle's hands and comforted him wordlessly. It was a long conversation that lasted all night, and in order not to disturb Uncle Ma, both of them tried their best to keep their voices low. During the conversation, she kept holding Tianle's hand with both hands, so she didn't make any transcripts or recordings, but she didn't need to record them, and all the words were deeply imprinted in her memory. She also had a strange feeling that night, as if there was some calm and indifferent listener above her head all the time while the two were whispering. Of course, Uncle Ma hung overhead, but at that height he couldn't hear it, not to mention that he had been intoxicated with astronomical observations. Then the stars are listening, and the heavens are listening. After doing so many sins (letting a boy be imprisoned by illness all his life, making 99.9% of living species extinct, and making the spirit of all things suddenly face a violent spatial collapse), at this time he is still calm, no sorrow, no joy, no guilt and no regrets. It's not surprising that his old man was originally a cold-faced and ruthless guy.
