Genius is just the threshold for me!

Chapter 355 Uncle Xu, Congratulations on your promotion!

With the high school final exams over, it was Saturday and the weekend. All the college students returned, and the neighborhood entered a brief period of liveliness.

In the afternoon, at the billiard hall across from the residential area, with a bang, Lin Dong pocketed the last black ball, number 8, and then swept the remaining three colored balls from Li Tao into his pocket.

"Brother Tao, you're down now, next one! Set up the table for the tee shot!"

"Damn, Lin Dong, you've gone crazy today."

Li Tao laughed and cursed, then took the billiard hall down to sit with Zhang Zihua, and Zhang Yihao came up next.

"Isn't this the normal level?"

After Lin Dong and Zhang Yihao set up the table for the tee, Lin Dong walked over, picked up his Coke, took a sip, and asked Li Tao and Zhang Zihua, "Brother Tao, Zihua, when are you going back to your hometown?"

"Stay for a week."

Zhang Zihua thought for a moment and said, "When it's time to fertilize the corn, I'll ask my grandparents to help out."

"I'm going to my grandma's place the day after tomorrow to stay for a while."

Li Tao replied, then suggested, "Shall we eat out tonight?"

"I promised to have dinner at Qingling's house."

Lin Dong shrugged: "Next time, let's make plans to eat in advance."

"You're having a good time!"

Li Tao immediately felt envious upon hearing this: "It seems like Su Yue's parents found out about me and Su Yue this semester. I feel like the way they look at me has changed."

"Stay calm and just be yourself."

Lin Dong shared his experience with a smile, saying, "Uncle Su and the others not saying anything is the best statement. You didn't see it, but Uncle Xu's face was always dark when he looked at me a few years ago—"

In their past lives, Li Tao and Su Yue were a pair of bickering lovers who got together in high school. Apart from breaking up once in college due to conflicts, they eventually got together in the end.

On the contrary, Zhang Yihao and Jiang Caiping, in their previous lives, Zhang Yihao's college entrance examination scores were not high enough, and he failed to apply for the Seven Sons of National Defense. He went to study at an ordinary undergraduate university. After graduation, he went to Zhejiang to do business with his uncle. Because of the booming foreign trade, he had a net worth of 100 million yuan before he was 30 years old.

But Jiang Caiping, who has always been quiet, doesn't like business dealings and the atmosphere of business socializing.

In the end, the two still broke up. Jiang Caiping returned to Chengdu, passed the civil service exam, and met and married a local Chengdu civil servant at a matchmaking event organized by her workplace.

However, in this life, because Xu Qingling studied more diligently and her grades were consistently among the top in her grade and ranked in the top dozens in the city, and because Xia Ran came over, she set a great example of genius for the entire residential community.

Faced with this pressure from other people's children, all the other kids except Lin Dong got into a rut and their grades improved significantly compared to their previous lives.

With Zhang Yihao's grades secured, his future path will be different, and Lin Dong doesn't know what the final outcome will be in this life.

"Damn it, we're just having puppy love, but you're having an early marriage, a childhood betrothal. How can that be the same?" Li Tao couldn't help but say.

"Lin Dong, it's your turn!"

At that moment, Zhang Yihao shouted from the other side of the pool table, "I'll use my big fancy ball!"

"Then you're finished. Just now, Brother Tao was just a big flower ball and I killed him." Lin Dong responded and took the club over.

"We'll talk after you win."

Without the slightest hesitation, Zhang Yihao raised his middle finger in response to these words.

boom!

Lin Dong smiled and potted the number 1 ball with one stroke, but missed the second ball.

The four of them chatted and played billiards for several hours. Lin Dong didn't deliberately calculate or control the game. He won and lost, but overall he won more than he lost.

"Dongdong!"

At six o'clock in the evening, Xu Qingling, Huang Qingyao, Xia Ran, Su Yue, and Jiang Caiping returned from shopping. Xu Qingling walked to the door and called out to Lin Dong.

"You're back?" Lin Dong turned around when he heard the voice and immediately smiled.

"Lin Dong, that's a pointless question."

Su Yue ran in, glanced at the balls Li Tao still had on the pool table, and immediately snatched the cue from Li Tao's hand: "Li Tao, you're a noob, let me do it."

talking.

Su Yue, watching Zhang Zihua getting ready to play ball, asked gossipily, "Zhang Zihua, I was chatting with Zhong Xi, and I heard she's going to travel to Zhongyuan Province this summer—what's going on between you two?"

"Under normal circumstances."

Zhang Zihua blushed, his cue slipped, and with a snap, the cue ball grazed the white ball and flew away.

Su Yue's eyes widened in surprise. "Two poles—Zhang Zihua, you're too kind!"

Seeing this, and then seeing Jiang Caiping walk over to Zhang Yihao to share the fruit she had just bought, Lin Dong shook his head, greeted Huang Qingyao and Xia Ran, and then went back with Xu Qingling.

"Wait a moment."

The two walked downstairs hand in hand. Suddenly, Lin Dong remembered something, turned to Xu Qingling and said, "I'm going back to get something."

o

"What else do you need?" Xu Qingling asked curiously.

"Get two bottles of wine."

Lin Dong took Xu Qingling home and brought two bottles of wine, along with the personnel transfer watch that Wang Xingguo had signed a couple of days ago.

"If you keep doing this, Dad will close the door next time he sees you carrying things over—" Xu Qingling saw this and immediately understood what Lin Dong was up to, and she was both amused and exasperated.

"Then I'll go empty-handed from now on."

Lin Dong smiled, took Xu Qingling's hand and went to the Xu family home. When they opened the door, some food was already laid out on the dining table.

Xu Ziming came out carrying a bowl of tender meat soup and happened to see the gift bag Lin Dong was carrying. His heart skipped a beat, and he asked, "What else are you bringing?"

"Last year, I took a few bottles of wine from my boss's house, saying they were decades old. You know how much my dad can drink—"

Lin Dong explained with a smile, "It would be a waste to leave it at home, so I brought it over for Uncle Xu to try."

"Did the leader's family take it? No wonder your dad scolded you—"

Xu Ziming was surprised, but then he was also a little excited and said to Xu Qingling, "Lingling, get Daddy a cup so he can have a taste."

Hearing this, and seeing how easily Xu Ziming had fallen for it, Xu Qingling asked with concern, "Dad, why don't you finish your meal before drinking?"

Although Xu Ziming has a high alcohol tolerance, he only drinks a little and doesn't drink excessively, so Xu Qingling and Zhou Xiaoyan usually don't interfere with his drinking.

But today, Lin Dong brought over some wine, and she was genuinely worried that Xu Ziming wouldn't be able to eat after drinking it all.

"Dad, just have a taste."

Xu Ziming said, "After dinner, you'll go for a walk with your mother—"

"Alright."

Seeing that she couldn't persuade him, Xu Qingling went to the side, picked up a glass, and Lin Dong opened the wine and poured a glass for Xu Ziming.

Xu Ziming looked at the pale amber-gold liquor in the glass, and smelled the faint aroma of aged wine and soy sauce. He then picked up the glass and took a sip.

In an instant, an extremely rich, mellow, and smooth taste spread from the mouth to the throat, followed by a lingering and long-lasting aroma that spread throughout the mouth.

"Did the leader really get this from his family? You can't buy this kind of liquor on the market at all—"

Xu Ziming tasted it carefully, and was somewhat surprised to take a second bite.

But after finishing his second sip, he suddenly noticed the documents in the gift bag Lin Dong had placed on the table, and his expression froze, a sense of foreboding creeping over him: "What's this?"

"Ahem, Lin Dong saw that Xu Ziming had seen it, so he couldn't hide it anymore. He took out the documents inside and handed them over: "Uncle Xu, congratulations on your promotion."

Xu Ziming looked at his name on the document, along with the notice that he was to concurrently serve as the head of the Technology Department/Final Assembly and Manufacturing Department at Chengdu Aircraft Industry Group's Aerospace Research and Production Base. He wanted to curse, but seeing the opened bottle of liquor, he didn't know how to start. In the end, he could only look up at Lin Dong and say, "Xiao Dong, can you take this liquor back?"

"Uncle Xu, this is a gift for you."

Lin Dong quickly took the remaining unopened bottle of wine to the wine cabinet, giving Xu Ziming no chance to back out.

"Hahaha!"

Zhou Xiaoyan came out with bowls and chopsticks, and seeing this scene, she couldn't help but laugh at Xu Ziming, saying, "I told you not to ask before drinking. You've been fooled before, and you'll be fooled again."

"Tell him not to bring anything over anymore; he's not welcome!"

Xu Ziming gritted his teeth and said, "I knew it, this kid bringing things here was never anything good."

"Okay, let Xiao Dong come empty-handed on the second day of the Lunar New Year next time."

Zhou Xiaoyan smiled and replied, picked up the document and looked at it, then looked at Lin Dong, who had washed his hands and come over with Xu Qingling.

He asked with some concern.

"Xiao Dong, what kind of rockets are mainly being developed and designed at the aerospace research and production base?"

"For now, we're using a small liquid oxygen/kerosene rocket to get the team used to its strengths. Once we're more proficient, we'll switch to a medium-sized rocket, and even a liquid oxygen/liquid hydrogen rocket with a higher boost level than spur. We won't be using any toxic rockets."

Lin Dong knew what Zhou Xiaoyan was asking.

The concern is that the rocket project at the aerospace research and production base might be using unsymmetrical dimethylhydrazine and nitrogen tetroxide as propellants, which could lead to poisoning.

The advantage of using unsymmetrical dimethylhydrazine and nitrogen tetroxide as propellants is that they can be stored at room temperature and can burn upon contact, eliminating the need for additional ignition devices in rockets. However, the disadvantages are that they are highly toxic and carcinogenic.

Although modern aerospace systems have a complete set of safety procedures, the products of propellant combustion are water and nitrogen, and propellant loading does not take place at the base, it still makes people worry.

"That's fine then."

Zhou Xiaoyan nodded, served Xu Ziming a bowl of tender pork soup, and then served Lin Dong and his daughter a bowl, urging them to eat.

"What is the purpose of having Chengdu Aircraft Industry Group (CAC) set up this R&D and production base?"

Xu Ziming calmed himself down, took a sip of soup, and looked at the guy sitting with his daughter, who was putting meat into Xu Qingling's bowl.

"It's just about setting up a space laboratory. Your godmother can ask the First Academy of Aerospace Science and Technology for help with the launch. There's no need to set up a research and development base yourself."

"By creating an industrial chain and utilizing the resources of the Xichang Launch Center, we can also boost the development of the Liangshan area."

Lin Dong picked up a piece of meat and said seriously, "In addition, the aerospace program and the space program, like the bio-industry, are undisputed core elements of the future."

Finally, after some research, I realized that current space technology is still too rudimentary, and there is still a lot of untapped potential.

"The technology is too basic?" Xu Ziming was taken aback.

"These are all technologies from the last century, and they've been used for patching and mending for over half a century."

Lin Dong nodded: "With the current underlying technology, even with reusable rocket technology, the cost of building a large space base is still too enormous."

At this time, the domestic launch cost was approximately 5 to 6 yuan per kilogram.

While current first-stage reusable rocket technology is advanced enough to save 80% to 90% of costs, the launch cost per kilogram still remains between 5000 and 1 yuan.

And this is still the near-Earth cost. If it's a geostationary transfer orbit or an Earth-Moon transfer orbit, the cost will be even higher.

In Lin Dong's view, this one space cost is simply insufficient to support the entire space age and space strategy.

"—Xiao Dong, you're so good to your godfather."

Xu Ziming sighed, then said with schadenfreude, "Keep up the good work."

Although he didn't know how Lin Dong planned to improve current aerospace technology, he had no doubts about Lin Dong's expertise in the technical and industrial fields.

Such a radical departure from the norm in the field of aerospace technology must put Wang Xingguo under immense pressure.

"Uncle Xu, I'm doing this to serve the country and promote the progress of human civilization. Don't think of me as someone who holds a grudge."

Lin Dong disagreed with this statement: "Their technique is slow and their skills are poor, so you can't blame me."

"Yes! You don't hold grudges—"

Xu Ziming ignored the kid, took a sip of his drink, and asked, "When will the J-20S project and the rocket project on the aerospace side start?"

"The J-20S will be launched tonight."

Lin Dong said earnestly, "The rocket will be ready in a few days. Uncle Xu, you guys go to the space base to familiarize yourselves with the docking process, and then it will be launched—"
