Genius is just the threshold for me!

[003]: You've taken over the space base project?

[003]: Didn't you say that once the first rocket project was completed by the end of the year and the team was fully integrated and familiar with each other, you would take over the second rocket project?

【003】: At such a young age, don't think about work even when you're out playing. The project can be slowed down a bit, there will be plenty of time in the future.

Around 6 PM, Lin Dong and Xu Qingling had dinner and strolled hand in hand in the free activity area. At that moment, the secure cell phone in his pocket started vibrating frantically, with one message after another popping up.

"Uncle Xu is scolding me."

Lin Dong took out his phone, unlocked it, glanced at it, smiled, and handed it to Xu Qingling.

003 was his nickname for Xu Ziming's secure phone, to prevent others from accidentally seeing the information and identifying the relevant people and relationships if the phone was left unlocked or used outside.

"You've taken over the space program?"

Upon seeing the message, Xu Qingling looked around to make sure no one else was there, then covered her mouth and leaned close to Lin Dong, asking in a low voice.

"Uh-huh."

Lin Dong nodded: "My godmother has other matters to attend to."

"I want to chat with my dad..." Xu Qingling smiled, took out her phone, and dialed Xu Ziming's video call.

Beep! Beep—

The video call was answered after ringing twice.

Xu Ziming and Zhou Xiaoyan appeared on the screen, with Xu Ziming asking with a smile, "Lingling, what's wrong?"

"Mom and Dad, what are you doing? Have you eaten yet?" Xu Qingling asked happily, then stretched out her arm to include Lin Dong in the photo.

"Eating..."

Xu Ziming turned around and adjusted the angle, capturing the food on the table in the shot.

But the next second, upon seeing Lin Dong, his smile vanished instantly, his face darkening as he slammed his hand on the laptop from a different angle: "Still working overtime? You've been busy all day!"

"Pfft—"

Before Lin Dong and Xu Qingling could react, Zhou Xiaoyan couldn't help but laugh and exposed them from the side: "Xiao Dong, don't listen to what your Uncle Xu said... He finished his work in the morning and went to have tea with Engineer Huang and the others in the afternoon when he had nothing to do. He only found out about what happened when he came back now."

"I'm talking about these things now, which are not in the plan and are extra work..." Xu Ziming explained from the side.

Xu Qingling smiled and said with concern, "Dad, if you have a lot to do, do it tomorrow. Don't stay up late."

"it is good."

Xu Ziming replied, noticing that Lin Dong's expression had improved considerably despite his displeasure: "Be careful when you go out, and bring security personnel with you..."

"Understood, Uncle Xu." Lin Dong nodded.

After chatting with Xu Ziming and Zhou Xiaoyan for a while, Xu Qingling hung up the video call and smiled at Lin Dong, saying, "You see, Old Xu is still quite easy to please..."

"Yes, yes, yes."

Lin Dong nodded and replied, "It's only easy to coax you when you're the one who takes action..."

Xu Qingling put away her phone and said happily.

Behind them, Huang Qingyao and Xia Ran came out together.

Looking at the Long March 5 rocket, still towering and clearly visible two kilometers away, shrouded in white mist, Huang Qingyao felt somewhat relieved.

"Ranran, does this propellant loading take this long?"

"The booster is fueled with kerosene 30 hours before launch, liquid oxygen 10 hours before launch, and liquid hydrogen for the main rocket core 6 hours before launch, because liquid hydrogen and liquid oxygen will continue to evaporate, and these two need to be fueled to maintain the liquid level until five minutes before launch."

Xia Ran chuckled and said, "The information racks in this viewing area all have popular science materials explaining... These white mists are formed by the evaporation of liquid hydrogen and liquid oxygen, and the low temperature causes water vapor in the air to condense."

Although rockets have heat shields, these shields cannot completely block out external heat.

Because liquid oxygen and liquid hydrogen have extremely low boiling points, one at -183°C and the other at -253°C, even a little heat conducted through permeation will cause them to evaporate and then dissipate through the pressure relief vents to form condensed mist.

Therefore, rocket launches, in addition to kerosene which can be stored at room temperature, also involve toxic substances such as unsymmetrical dimethylhydrazine and nitrogen tetroxide.

The remaining propellants, such as liquid oxygen and liquid hydrogen, must be continuously supplied until five minutes before launch to ensure that the liquid level does not drop.

"No wonder the foundation is industry. The supporting engineering for the constant refueling of liquid hydrogen and liquid oxygen is something that most small countries can't handle."

Huang Qingyao sighed, then seemed to remember something, glanced ahead, and pulled Xia Ran aside to whisper gossip, "After watching the Long March 5 launch tonight, are you going to serve me in bed?"

???

Xia Ran paused for a moment, then realized what Huang Qingyao was talking about. She patted her and couldn't help but say, "I just wanted to talk to Lin Dong about something. What do you mean by 'serving someone in bed'? That's so awful... Yao Yao, can you please stop watching so many messy TV dramas? It'll damage your IQ."

"The first step of a long march, rounded up a bit, is about right."

Huang Qingyao shook her head, looked at Lin Dong and Xu Qingling chatting hand in hand in front of her, and sighed softly, "Time flies, seventeen years old, soon to be eighteen."

These two kids, Aunt Zhou and Aunt Xia started arranging a marriage between them when we were in fourth grade, and I never expected that it wouldn't have changed after all these years...

Sister, your skills aren't very good.

Aren't all the online sayings that a green plum can't compete with a gift from heaven?

"How come you, who suddenly appeared in front of Qingling, don't even have the courage to say a few words to Lin Dong? The only time you spoke to him face-to-face, you needed alcohol to help you speak. Is the Empress's authority really that great?"

"...Yao Yao".

Xia Ran looked at Huang Qingyao's short hair and chuckled, "You have short hair, are you calling it short hair...?"

"My hair has been like this since I was a child!"

Huang Qingyao remained completely unfazed and laughed, "I'm not like you, a loser who's kept your hair long for years and then cut it short."

"..."

Xia Ran was now a little too hurt by the provocation, and glared at Huang Qingyao through gritted teeth, saying, "You asked me to come out for a walk just to annoy me, didn't you?"

"So, what happened when you went to see Lin Dong tonight? Tell me about it."

Huang Qingyao said with a gossipy expression, "I want to see how this guy reacts after being tricked like this. In all these years, I've never seen him show any surprise or defensiveness..."

"If you're so capable, come along." Xia Ran calmed herself down and said lightly, "Like you said, don't be a coward."

"Never mind, I'm afraid he'll hit me."

Huang Qingyao shook her head regretfully: "...The strength and stamina this guy showed while swimming could have easily beaten me up. He's just being polite to you. I grew up with him, and he's really capable of taking a beating."

[Beep! Beep beep—]

[30 minutes until launch. All spectators and staff, please return to your positions and do not move around without permission!]

After chatting for a while, a broadcast suddenly came from the launch center. Huang Qingyao and Xia Ran exchanged a glance and turned to walk towards the viewing area.

Lin Dong and Xu Qingling, who were in front, also turned around and walked together towards the viewing center.

"Wow! It's about to launch!"

Lin Dong, Xu Qingling, and the others returned to the viewing area and sat down in their seats. Su Yue, who had arrived earlier, excitedly said something next to them.

"A height of 56.97 meters, a diameter of 5 meters, a takeoff mass of 867 tons... It's hard to imagine that such a behemoth will soon be flying into space."

"In the fifteenth month, you actually still look at data parameters?" Huang Qingyao exclaimed in surprise.

"That's right. It's my first time watching a space launch, so I definitely need to look at some information to feel more involved," Su Yue replied in a lively voice, making a very reasonable point.

Other family members of aerospace workers nearby, especially some retired people with white hair who had been invited to watch, couldn't help but smile as they watched Su Yue's lively and happy demeanor.

"Young man."

A retired man next to Lin Dong, whose hair was completely black and who looked to be over seventy, smiled kindly at Lin Dong and his group, saying, "You're all family members from Chengdu Aircraft Industry Group invited by Xiao Su?"

Xiao Su?

Lin Dong was taken aback for a moment, then realized that the other person was referring to Su Ruohua, and immediately smiled and said, "Yes, we all call her Aunt Su."

In front of outsiders, Lin Dong did not use the terms for godmother or empresses in the Sichuan region, but instead asked them to use the more common term "auntie" instead.

"Grandpa, where did you come from?" Lin Dong asked politely after answering the question.

"I'm from the Central Plains, and I've been retired for almost twenty years. I didn't originally want to come, but since it's the first large rocket, I thought I could still make it and come see it..."

The old man smiled, looking at the rocket two kilometers away, his eyes shining with joy: "More than 800 tons of takeoff weight, 1060 tons of takeoff thrust, and 25 tons of payload."

Before we retired, we wouldn't have even dared to dream of a rocket like this... With this, our space station can be launched into space.

"Grandpa, in a few years, we will have heavy-lift rockets with a takeoff weight of 3500 tons, thrust of over 5000 tons, and a payload of 150 tons..." Lin Dong said with a smile, "The Long March 5 is just the beginning."

"3500 tons takeoff weight, over 5000 tons of thrust, 150 tons payload... That's even bigger than the Saturn V, and its carrying capacity is even stronger."

The old man exclaimed in surprise, then shook his head and said, "I can't see it anymore, I can't see what you're talking about... I'm content to have seen this large rocket launch today."
