Chapter 2327: Academician Cheng's visit

What Director Lu said was: Chief, Elder Cheng came to visit you suddenly...
When Song Lao heard this, he could not help but frown slightly, looking a little embarrassed.
Seeing this, Xia Ruofei said directly: "Grandpa Song, is there a visitor? You go to meet us! We are our own people, it doesn't matter."
Song Lao said with a hint of apology: "Ruofei, it is Academician Cheng Rulong who is here. I am about the same age as him, and we have a very good personal relationship, but it is really not easy to refuse..."
Director Lu also explained: "Ruo Fei, the chief knows that you are coming today and has pushed all the schedules, but Academician Cheng never needs to make an appointment when he sees the chief. This is... a coincidence..."
Xia Ruofei said with a smile: "It's okay! It's okay! Grandpa Song, then you can meet Academician Cheng! That...I want to avoid it! Director Lu, please arrange a place for me to stay for a while!"
Song Lao waved his hand and said, "That's not necessary, Cheng Rulong is not an outsider, you can also meet and see together... Xiao Lu, please invite Academician Cheng to come in!"
"Yes!" Director Lu said, and hurriedly walked outside.
"Grandpa Song, is it really inconvenient?" Xia Ruofei looked at Song Lao and asked, "As far as I know, Academician Cheng's research field is related to ballistic missiles and aerospace, in case he and you need to discuss some secrets It's not appropriate for me to be there..."
Song Lao smiled and said: "Ruofei, I'm a retired person, how could Cheng Rulong really talk to me about those confidential matters? Besides... I don't understand professional matters, so why did he tell me? Just relax! Rulong often comes to see me, sometimes just to play chess, chat, drink tea, how can there be so many national affairs to talk about?"
"Oh... that's fine!" Xia Ruofei said.
At this time, there was a sound of footsteps outside, and before Xia Ruofei saw anyone, he heard a very angry voice: "Haha! Lao Song, this uninvited guest of mine is here to drink tea again!"
"Come here! It just so happened that one of my juniors brought me a lot of good tea! Drink whatever you want, this time I will definitely not be poor!" Song Lao also responded with a smile on his face.
Then, he smiled and said to Xia Ruofei: "What am I talking about? This guy is here to drink tea."
At this time, Director Lu walked in through the yard with a slightly fat old man. Xia Ruofei looked carefully, and it was Academician Cheng Rulong who came.
Xia Ruofei knew that the white-haired old man who looked a little fat in front of him was actually a senior expert in the army and enjoyed the treatment of a general, but he was not wearing a military uniform today.
Song Lao also stood up and took two steps forward, Xia Ruofei naturally did not dare to neglect, and stood up.
"Old Cheng, your nose is really smart! Did you come here smelling the aroma of tea?" Song Lao smiled and said, "My junior just brought me some good tea, and you appeared right away!"
Cheng Rulong looked at Xia Ruofei and said, "Yo! Is there really a guest here? Lao Song, I'm a bit presumptuous!"
"No, no!" Song Lao said, "This is one of my juniors, my own family. By the way, he brought the tea here. If you can drink good tea today, it's because of his blessing!"
Xia Ruofei hurriedly stepped forward and shouted with a trace of respect: "Hello, Academician Cheng, my name is Xia Ruofei, I'm Grandpa Song's junior..."
Cheng Rulong smiled and nodded towards Xia Ruofei, and said, "Well! Lao Song told me about you, you are a good boy!"
"You have passed the prize!" Xia Ruofei said.
At this time, Song Lao greeted: "Don't stand and talk, come and sit! Ruofei, don't be idle, the task of making tea today is handed over to you!"
"No problem!" Xia Ruofei smiled and nodded, then walked over and sat behind the tea tray, and started to make kung fu tea with ease.
Old Song said to Cheng Rulong with a smile: "Old Cheng, this junior of mine is from the southeastern province, which is a big province of tea! His skill in making tea with one hand is very impressive! You have a good time today!"
"I heard you compliment several times, but I want to try it. What's the difference between the tea this young man made and yours!" Cheng Rulong said with a smile.
Xia Ruofei had a smile on his face, didn't speak, just brewed tea seriously. When he completed a set of kung fu tea process, he was very smooth, and it seemed to have a special rhythm, which made people feel very comfortable.
After a while, the whole house was filled with the scent of tea.
Cheng Rulong took a breath and said, "This scent seems to be really stronger!"
At this time, Xia Ruofei had already brewed the tea. He poured the clear tea soup from the justice cup into the tea tasting cup, and then gently pushed it in front of Song Lao and Cheng Rulong. He smiled and said, "Please drink tea, two elders!"
Song Lao and Cheng Rulong nodded, and at the same time held up their tea cups. They first smelled the fragrance of the tea, closed their eyes and felt it, and then put it to their mouths and took a sip.
The two let out a sigh of satisfaction at the same time, and then Cheng Rulong said, "It's really good craftsmanship! This tea fragrance is very special! It has a long aftertaste!"
"This is Ruofei's ability. It's obviously the same tea and the same water, but I just can't make this taste."
"Grandpa Song, you've won the prize, it's just practice makes perfect!" Xia Ruofei smiled, "The two of you will have a second taste of tea in a while, and the taste will have some subtle changes..."
"Okay!" The two nodded at the same time.
In this way, the three of them sat around the tea table, Xia Ruofei brewed tea with ease, and the three of them chatted while tasting tea.
Song Lao was right, Cheng Rulong didn't come here to talk to him about the parameters of those high-end missiles. Everyone was talking about major national events, current news and the like.
However, while chatting, the topic unknowingly turned to the direction of Cheng Rulong's research. Of course, it's just small talk, and it doesn't involve confidential content.
"Old Cheng, some time ago we entered space with another batch of astronauts, and the performance of the Chang-2 rocket is as stable as ever!" Song Lao said with a smile, "You are a pioneer too!"
The principle of rocket technology and missile technology is actually the same. Cheng Rulong is definitely the well-deserved founder of China's aerospace industry. He is the leader of the first generation of aerospace science and technology workers in China. He is still in his 80s and still undertakes many related scientific research tasks. .
The backbone of the manned space rocket system today can be said to be Cheng Rulong's disciples and grandchildren.
Therefore, Song Lao's words are not touted, they are completely truth-seeking.
Cheng Rulong was also very happy when he heard it, he said with a smile: "Our country's aerospace industry has indeed developed very rapidly in recent years. This is the advantage of being a latecomer that I have always emphasized. Although we started later than other big countries, but after With the efforts of generations of astronauts, we have successfully achieved leapfrog development!"
Song Lao nodded happily and said, "Yes! The high-thrust rocket you led and developed played a decisive role in this! Just imagine that if we didn't master the technology of high-thrust rockets, we couldn't send the heavy space station components into space at all. , the establishment of our country's own space station is an empty talk... Of course, the manned rocket is also a contributing factor, and the stability is as good as ever!"
Cheng Rulong smiled and waved his hand and said, "It's all the children's credit. Now I rarely do specific scientific research projects, and I still check the general direction for them. After all, age is here! I'm running out of energy. , the years are not forgiving!"
"There are talented people in the country, and all of your disciples have also provoked one by one. This is very good!" Song Lao smiled and said, "People still have to obey the old, it's not good to be brave!"
"You're right!" Cheng Rulong said with a wry smile, "When I was young, I was engaged in scientific research and it was common to stay up all night. But at this age, let alone staying up all night, I use my brain a little bit more, and I can spend several days on it. exhausted……"
Speaking of this, Cheng Rulong couldn't help but say, "But Lao Song, you are getting younger and younger!"
The smile on Song Lao's face couldn't stop, he looked at Xia Ruofei and then said: "The body depends on maintenance and conditioning! You are still active in the front line of scientific research, I have already retired and not asked about the world, we can be the same ?"
"I'm working hard!" Cheng Rulong sighed, "I'm also taking a break from my busy schedule today. I feel that I'm too boring in the laboratory, so I thought about coming to you to take a breath and relax... But it's really worth it! Xiao Xia The tea brewed is really good! After drinking it, I feel refreshed!"
Xia Ruofei laughed secretly in his heart. After listening to the chat of the two old people just now, he secretly added a small amount of spiritual flower petal solution to the tea.
With his cultivator's elusive means, Song Lao and Cheng Rulong naturally couldn't find it.
Song Lao's body has been conditioned quite well, so his feeling is not so obvious, and Cheng Rulong is very tired and has some basic diseases, and it is the first time for him to drink Lingxin flower petal solution, so It feels quite strong.
Song Lao didn't know why, he just said with a smile: "In that moment, when you go back, take some tea leaves, and you can make some for yourself later!"
Cheng Rulong waved his hand and said, "There's no need for that! I don't know how to make kung fu tea. I'll come to you when I want to drink it. It's the same..."
"You..." Song Lao couldn't help but shake his head with a smile and said, "Speaking of when you were doing scientific research back then, you were just like Saburo working so hard, you just lost sleep and food, who would have thought that you are too lazy to make tea by yourself? If you don’t want to, I just want to drink ready-made! If Fei can brew tea so well, with your IQ, how can you not learn?

"What did you learn to do that didn't help the project?" Cheng Rulong waved his hand and said.
Xia Ruofei couldn't help showing a smile when he heard the words, but at the same time he admired Cheng Rulong even more. In fact, the older generation of scientific researchers are like this. They are all focused on their own fields. They may have low living ability and can't even take care of them. Be good to yourself, but it is precisely because of their simplicity of mind that they put all their energy into scientific research to achieve such dazzling results.
Song Lao laughed and said, "This is your style!"
Then, Song Lao turned the topic to aerospace again, he said with a smile: "Old Cheng, our country's aerospace industry has ushered in a booming harvest period, and the efforts of your older generation of scientists have not been in vain! Look! Look at the past few years, we have taken one step at a time. First, we became the third country to master manned spaceflight technology, and then became the third country to master rendezvous and docking technology and spacewalk technology. Now we have begun to build our own. The space station is over, and in a few years, our country's own space station will become the only space station in low-Earth orbit, what a dazzling achievement!"
Cheng Rulong smiled and nodded and said, "Yes! We were a space power in the past, and now... we are also a well-deserved space power! But... From the perspective of all mankind, space exploration has just started, and mankind wants to truly go deep Sora, there is still a long way to go!"
Xia Ruofei listened to the discussion between the two, and was also a little interested, and couldn't help asking: "Academician Cheng, what do you think space exploration has to achieve in order to achieve a staged success? I think we humans are now. It's amazing to have been able to stay in space for a long time!"
Cheng Rulong smiled and said, "Young man, I'm not belittling myself, not only our country, but also the other two aerospace powers are just starting to explore the sky. If this road is 100 meters long, we may only be able to. Walk a meter or two!"
"Is the gap so big?" Xia Ruofei couldn't help but be a little stunned when he heard the words.
Cheng Rulong said with a smile: "Take the long-term stay in space you just mentioned! Yes, our country's astronauts will soon implement a six-month rotation system to ensure that the space station is always on duty, and each batch of astronauts goes up, They all stay for about six months, and the same is true for the International Space Station, a few months of stay has become the norm, but..."
Speaking of this, Cheng Rulong turned and said: "This actually requires a price. What is the price? It is the health of the astronauts. Living in a weightless environment for a long time will cause a lot of harm to the body, including cardiovascular dysfunction, Bone loss, decreased immune function, muscle atrophy, etc., etc., so... a six-month stay is actually a relatively limited period of time, and if it goes longer, some of the damage will be irreversible."
Cheng Rulong took a sip of tea and continued: "After our astronauts return to Earth after a six-month mission, they will need at least half a year of recovery. Through various advanced and scientific means of recovery, their bodies can basically return to normal. Get back into training, it's all the hazards of a zero-gravity environment."
"If we are going to carry out deep space voyages and explore deeper space in the future, then this will actually be a difficulty." Cheng Rulong said, "For example, if you explore Mars, the current technology may take up to several months to fly, then What will happen to the bodies of the astronauts then? Even if they reach Mars, but they can't even walk, how can they be put to work?"
Xia Ruofei couldn't help but asked curiously when he heard the words: "Academician Cheng, can't our technology simulate the gravitational environment in space?"
