With enough food and drink, Li Zheng and Lin Yuejing didn't mean to go home, so they simply walked to the beach, stared at the stars, and chatted with the sea breeze.

Even here, you can still see the brightly lit launch tower five kilometers away.

Lin Yuejing, who was above alcohol, couldn't help himself, standing on the beach and gesturing without pointing, after all, no one knew rockets better than her.

To the layman, the launch of the Yellow River 2 is not much different from each previous rocket launch.

But for Lin Yuejing, who has been in the aerospace research institute since his mother's stomach, this moment is full of historical significance.

Once the launch is successful, Yellow River 2 will become the top five in the history of carrying capacity, and the top three heavy-duty launch vehicles in active service will also become an important milestone in the history of the development of China's aerospace.

Accompanied by Lin Yuejing's guidance, behind this launch, a history of human spaceflight development slowly unfolded in front of Li Zheng.

There is only one theme of this history-

Send heavier things to heaven.

There are usually two data to evaluate the carrying capacity of the rocket.

One is LEO capacity.

The second is GTO capacity.

The former requires an orbit altitude of more than 2,000 kilometers, while the latter needs to send satellites to 36,000 kilometers of deep space, so GTO capacity is mostly less than half of LEO.

Taking the GTO as a reference, the highest record in history has been maintained by Saturn V of the magnesium country for half a century.

48.6 tons, this is the historical limit of the launch vehicle.

It is also the largest rocket in history, with a take-off weight of 3038.5 tons.

This rocket carrying the limits of mankind is truly against the sky.

It is loaded with thousands of tons of chemical fuel, with a brutal force, just to send a 1.6% of its own weight to deep space.

The former Soviet Union quickly took the time to launch the equally famous N1 launch vehicle, but all four test launches ended in failure.

But even if its launch was successful, the GTO capacity was only 23.5 tons.

Later, as the Cold War cooled, the space race between superpowers also ended.

Those who are against the sky have since lost their meaning.

After completing the last mission in 1973, Saturn V announced his retirement.

The next big guy "Energy" of the former Sulian only successfully launched in 1987, reaching a GTO carrying capacity of 22 tons.

No one has broken these records.

Today, the 14 tons of Yellow River No. 2, although not able to surpass this record, has qualified for the challenge.

This launch will triple the capacity limit of the Chinese launch vehicle across times.

There will always be those who go against the sky and go against the sky.

"This is my mother's task." Lin Yuejing stared at the brightly-lit tower on the other side of the bay entrance and gently lifted the air in his hand. "Heavier things are sent to heaven.

Li Zheng recalled this history and imagined the moment when the rocket took off.

At this point, he just wanted to say.

Your mother is amazing.

But still hold back.

In order not to fall behind Lin Yuejing's family too much, he had to stand up to the old Li's design.

"My dad, why don't he have his task." Li Zheng stood on the reef and stood down. "That's to cut off more tumors, and of course damage the nerves of the patient as little as possible."

"..."

"Ah, they are all great people." Li Zheng sighed, and suddenly remembered something, "But I remember you said, instead of putting your life on such a task, it is better to look at the stars, so you The astronomy department just selected."

"Um..." Lin Yuejing's head gradually fell down, "even if my mother can work until 70 years old... even if you can triple the capacity again, and triple it again, what about... not to mention her, even if it is I, the greatest limit I can imagine in my life, can only be a manned Mars landing..."

Li Zheng turned his head and asked a bit tangled: "But you will still cry when you look at the Yellow River 2..."

"Yes... but I also know... I can't fly far in my life..." Lin Yujing clenched his fists and looked down at the waves under his feet. "You probably have to say something more critical... "

"No, no... I understand a little bit now, no one has the right to direct the lives of others." Li Zheng sighed and jumped off the reef. "You are too clever, just like solving a problem. You will immediately come up with extreme results. Looking at spaceflight from your perspective, you can always see the struggle and despair through it... but you just like it..."

Li Zheng said, putting a hand on Lin Yujing's shoulder.

"At the basketball court meeting, you said that your troubles are'space-time scale'."

"Now, I probably understand it."

Lin Yuejing trembles, raising his hand to pull him away, but his hand slowed down in the air.

However, Li Zheng had no choice but to withdraw his hand and returned to the negative position.

"Zao Yun..." Lin Yuejing scolded, and asked, "I remember you said at the time, your trouble is that there is too little time, too much knowledge."

"Why, I forgot." Li Zheng laughed with a hand. "It's really a young man to say such things."

"Hmm..." Lin Yuejing kicked the sand and said, "I also began to understand what Zhao said."

"Hehe." Li Zheng chuckled lightly. "I don't believe it."

Lin Yuejing didn't care about him. He stood at his own place and watched the waves roll, letting his shoes sink deeper and deeper in the sand.

"If there are many ways."

"In my case, I will see the finish line at a glance."

"Then choose the most satisfying path."

"In your case, as long as you choose a path, you will go dumb and go down."

"You don't see the finish line at all and don't care about the finish line."

"Where you can go, where is the end."

This last sentence instantly shocked Li Zheng's goose bumps.

This damn...is the difference between the score of 55 and the perfect score...

"I...I believed..." Li Zheng shuddered. "Some people understand rockets better than you, but no one understands me better than you."

In the moonlight, Li Zheng couldn't see Lin Yuejing's complexion either, only knowing that she turned her head and slipped back: "Who wants to understand you, get up!"

"Haha." Li Zheng smiled and chased, "I don't, I will post."

"Disgusting, I only post to Xiaoke and Mengxi."

"But Xiao Ke also posted with me."

"Jack, I won't post her anymore."

...

Back home, after saying good night, Li Zheng helped Lin Yuejing close the bedroom door.

Then take a bath, go to bed, and sleep separately.

Everything is natural, noble and righteous, without any embarrassment.

It was the other two who, after finishing a day's work, got into trouble.

[Li Yi: Are they asleep? 】

[Shen Tinglan: I didn’t ask. 】

[Li Yi: I did not ask. 】

[Shen Tinglan: Do you ask? 】

[Li Yi: No, you ask. 】

[Shen Tinglan: I am not good to ask. 】

[Li Yi: I... forget me to ask. 】

...

[Li Yi: I didn't return to me, it should be asleep. 】

[Shen Tinglan: Quietly back to me, she hasn't slept yet. 】

[Li Yi: So...hey...]

[Shen Tinglan: Teacher Li, why do you sigh? 】

[Li Yi: I... suddenly thought of a tumor that straddled the spine and chest. 】

[Shen Tinglan: The scale of doctor chat is terrible (surprised face)]

[Li Yi: Well, you have a rest, there will be news to inform each other tomorrow. 】

[Shen Tinglan: Well, Teacher Li will take care of them tomorrow. Now I have a sense of guilt in opening WeChat at this time. I have to work on the spot all the time so that my comrades’ emotions can be stable. 】

[Li Yi: understand, understand, wait for good news! 】

[Shen Tinglan: (Good night)]

...

The next morning.

When Lin Yuejing woke up, the first thing he did was to open the curtains and walk to the balcony of the townhouse, yawning and looking at the tower.

Confirm that it is intact and that there are no rockets on the shelves.

It seemed that she would disappear if she didn't look.

However, Li Zheng was already sitting in the living room, glancing at Lin Yuejing through the floor-to-ceiling window of the living room, and said with a smile: "Are you a cat? You have to confirm the territory."

Lin Yujing just turned around and was about to scold, but cried out "wow" again.

On the table, there were several plates and coffee!

She then sniffed her nose and dived into the living room.

It is fried fish steak!

There are also ham sausage, lettuce and cereal milk porridge.

"You...you..." Lin Yuejing trembled and took a seat, picked up the chopsticks and aimed at the Baihuahua fish steak. "You have this skill.

Li Zheng closed the book and said with a sneer: "I can provide some conditions for you to eat, but I am generous and ambitious. Hurry and eat."

Needless to say, Lin Yuejing has already caught it.

The first chopsticks.

Crushed!

The second chopsticks.

It's broken!

She was anxious.

Picked up the plate and grabbed and ate.

Lin Yue chewed the fish steak, and instantly got up: "Where did you buy it, there is this in a small supermarket outside?"

"There are no supermarkets, but there are markets." Li Zheng snorted softly and took out a handwritten guide book to show Lin Yuejing with a smile.

"I have confirmed before coming."

"Local food purchases mainly rely on early and late gathering."

"The market opening hours are 6-8 am and 3-5 pm, and only during these two periods will there be excellent food supplies."

"If you want to eat fish, rush to the morning market at 6 am to buy the freshest and fattest."

Lin Yuejing was so shocked that he dropped all the fish pieces: "You started at 6 o'clock?"

Li Zheng grinned and raised his hand to cover his eyebrows.

"No, it's 5 o'clock."

"Just now, just a superficial guide."

"There is a deeper guide."

"True **** diners are purchased directly from fishermen."

"At about 5:30, fishing boats salvaged at night and early in the morning will return to the port one after another."

"Buy directly from their hands to get the best, freshest and most cost-effective seafood."

"By the way, eating the candidate oysters at noon is already in the kitchen."

"Understood, this is foolproof travel."

Lin Yuejing was shocked by Li Zheng's series of strategies.

"Are you at home...the same?"

"..." Li Zheng swallowed and snorted. "At home, I would order takeout, and at most cook porridge..."

"Giggle..." Lin Yuejing snickered and stopped talking, only to bow his head and continue to eat hard.

"Don't get me wrong, it doesn't matter to you." Li Zheng explained with a trembling face. "I just have to make the travel plan complete."

"Uh huh."

"Don't be passionate."

"Oh oh."

"I went to study... remember to brush the bowl."

"No no no."

"You have to do something? It will become a pig in this way."

"Lulu."

"Ah... how can I explain to Aunt Shen..."

"Okay, brush it." Lin Yujing laughed at the oatmeal, "wait and go out and buy some furniture. I want to put lounge chairs and hammocks on the balcony."

"Okay, I sleep in a hammock."

"I sleep."

"Think about who made these foods?"

"Uncle Fisherman!"

"..."

...

Therefore, this morning's theme naturally became home furnishing.

There are also many home improvement stores in the town because there are new properties nearby.

In the morning of the morning, Li Zheng only had a set of office chairs and desks for studying.

Lin Yuejing purchased lounge chairs, hammocks, cartoon beds, barbecue grills, clothes hangers, plush toys, hanging pictures, etc...

After more than one o'clock in the afternoon, these things were finished, and Lin Yuejing was lying on the sofa tired.

But when Li Zheng appeared with garlic oysters on, she jumped up again.

After a full meal, tidy up the table and lie down on the balcony.

Fortunately, it was a cloudy day, not drying, and a little breeze.

The two were on a rattan lounger and one on a hammock, and they slept to death without a few words.

At less than three o'clock, Li Zheng woke up first, and also got up and glanced at the tower first. After confirming that there was no change, he looked to Lin Yuejing.

This guy, sleeping in a hammock, must sleep on his stomach, and he also holds a large Stitch...

Li Zheng was too lazy to take care of her, went into the house to boil water, soaked a pot of local herbal tea, and then he sat at the newly-built desk in the living room and began to study.

Unlike the past, this time the theme is biology.

There are not many books, it is nothing more than a dozen college textbooks.

After all, they are self-taught people who have chewed on chemistry and physics. Reading these materials is like reading extracurricular books.

Moreover, biology and chemistry have countless similarities. Many of the biological knowledge he read, he had basically understood when he was studying chemistry, or the knowledge was floating at the time, and now he has seen the perspective of biology and understands it a little deeper. .

In general, the rules of biology are more straightforward than physical chemistry. There are few basic principles, and more are the surface laws summarized by experiments.

And these rules often need to be memorized for single student.

For example, the synthesis and decomposition of things such as amino acids and proteins, from a biological point of view, need to remember a lot of knowledge summary, but do not know why this is the case.

But combined with organic chemistry, you can deeply understand the principles of it, and you can infer naturally without deliberate memory.

As for the ten thousand years of difficult fruit fly mating...

This is more comfortable to do with a mathematical model.

Overall, the current biological learning is probably like a brain radio gymnastics, soothing and energizing spirit. After learning, just brush the IPHO puzzle.

After more than half an hour for Li Zheng to get a few biological books, Lin Yujing also rubbed his eyes and picked up the balcony door.

"Um... it's almost four o'clock..."

"Yeah, it's four o'clock and I haven't studied..." Li Zheng shook his head. "Don't you feel guilty..."

"Come out to play, learn what to learn." Lin Yuejing smiled, went to the bathroom and rushed his face, then whispered into the house, took out a small rectangular bag, and a few power cords and TV lines.

Li Zheng glanced and ignored her.

But she saw that she was walking around behind the TV again. After whispering, she sat cross-legged on the sofa.

The TV screen lights up.

A cat Leo appeared in the cover of the car.

A cheap voice came immediately after the TV-

"MorioKart-eight!"

Then there is the music that children like.

"Beep~Beep~~" Lin Yujing held the steering wheel and beeped.

"You..." Li Zheng looked at a lot of Ren Tian Tian characters on the screen, and his face was pumped. "The only luggage you carry... is this thing?"

"There is still." Lin Yuejing patted the black small bag. "Maurio Brothers U, the big drum master, the dance is full, the Animal Island Friends Association, there are so many...enough to play for a year."

"Fuck..." Li Zheng covered his head and said, "You whisper, don't disturb my study."

"Oh."

Lin Yuejing really whispered.

But Li Zheng was still disturbed.

He always looked up at the TV from time to time, watching a bunch of silly things while driving and throwing things at each other.

In the end, Lin Yuejing operated Kuba, sorry for the second.

"Still stupid." Li Zheng grinned, "The red tortoise can be traced, what is thrown, and it will remain the first dirty one, won't you win the championship?"

"You're stupid!" Lin Yuejing yelled, "I don't need a red turtle, I couldn't even get in the first three."

Li Zheng waved his hand and said: "Such a simple children's game, you can top three without props hard open."

"Try it if you have the ability." Lin Yuejing said with a mouthful, "Cloud player, Yun Zha."

"Oh." Li Zheng chuckled, "Sorry, the person who can seduce me to play the game is not born yet."

"Oh, that's right." Lin Yujing suddenly rubbed his chin. "You are a C2 book and you are not qualified to race with me."

"What does this have to do with C2..."

"Anyway, now all female drivers take C1, but only C2... people with problems in the cerebellum... or people with disabilities?"

"You are enough...just too short...C2 is faster."

"Forget it, for C2, just open C2, don't bully you." Lin Yujing waved his fist, "Come on, work hard, be strong."

This is intolerable.

Li Zheng clapped the table and got up.

"Are there any steering wheels!"
