Genius is just the threshold for me!

7:40 PM.

After arranging everything, Xu Ziming took the washed lunchbox and led Lin Dong and the other person back to their residential compound.

Although the laser solution has been confirmed to be feasible for DD9 production, the corresponding lasers still need to be provided by Lin Weiliang, and the laboratory that provides the lasers also needs to be modified simultaneously.

This process will take approximately three to five days.

Once the laser equipment arrived, the laboratory renovation was complete.

The next step is to optimize the entire production process and maximize the production qualification rate. Then, the process can be replicated, and mass production factories can be built.

"This third-generation single-crystal material..."

Lin Dong and his companion followed behind Xu Ziming, the three of them stepping on the last rays of the setting sun.

At that moment, Xu Qingling, watching Xu Ziming's retreating figure, suddenly remembered something and whispered in Lin Dong's ear, "Is this related to you?"

She didn't understand the research, but she could read, and because she had known about Lin Dong's situation since she was a child, she didn't deliberately avoid talking to him.

In the past few months, when Lin Dong was busy with his work, she sometimes helped him tidy up. Besides formulas and data, there were also some words related to single-crystal materials.

Considering this in conjunction with today's events...

obviously.

Lin Dong and Wang Xingguo are most likely hiding something from Xu Ziming and are planning something. This materials project will most likely fall to their father.

Lin Dong didn't speak, but simply nodded softly.

"Does Dad not know the situation yet?" Xu Qingling asked again.

"right."

Lin Dong responded softly, "I'll go back with you. My godfather will be coming over in a bit to talk to Uncle Xu about this..."

"If you come to my house again, Dad will chase you away with a broom..." Xu Qingling rolled her eyes at Lin Dong, about to say something.

At this moment, Xu Ziming, who was in front, turned around and glanced back.

Seeing the two walking side by side, whispering to each other, he frowned and said, "Lingling, hurry up."

"oh."

Xu Qingling quickly quickened her pace, ran to Xu Ziming's side, and held out her hand: "Dad, I need to call Mom."

"You're already back, why bother making a phone call..."

As Xu Ziming spoke, he still took out his secure phone, unlocked it himself without letting Xu Qingling operate it, and dialed Zhou Xiaoyan's secure number.

External electronic devices are not allowed in the core area, but specially designed and secure internal equipment is permitted.

After all, once core employees join, there will inevitably be various forms of communication and interaction in their work and life; they can't just shout or wander around aimlessly.

"Hey...Mom...when are you coming back...umm, I miss you..." Xu Qingling said a few words to Zhou Xiaoyan affectionately, then hung up the phone and handed it back to Xu Ziming.

"Your mother went out?" Xu Ziming took the phone and casually put it in his pocket.

"Yes, I had dinner and then went to Aunt Fang's to play mahjong. I said I'd be back now."

Xu Qingling answered obediently.

The "Aunt Fang" she mentioned is Yang Fangfang, Huang Qingyao's mother, and Zhou Xiaoyan's best friend with whom she often chats and goes shopping when she has free time.

"Wangcai, let's go home."

Soon, the three of them left the core area.

Xu Qingling barked at the mechanical dog that was still lying on the grass, and waved to the security personnel on duty, saying, "Uncle, we're going back."

"Minister Xu, Qingling, Xiaodong, please take care."

The security personnel responded with a smile.

He then opened the computer's visitor registration records and added a record to the entry of Lin Dong and Xu Qingling into the core area, indicating that they had left and that Minister Xu had personally led the procession.

"The elastic energy storage design of this robotic dog's limbs looks quite effective..."

As they left the core area, Xu Ziming looked at the mechanical dog following Xu Qingling, and then carefully observed the light and quiet movements of the mechanical dog as it took its steps. He couldn't help but say something to Lin Dong.

"My dad said that compared to a rigid design without elastic energy storage, it improves movement efficiency by 57%, increases battery life, makes movement smoother and faster, and also reduces the impact and wear on the joint motors..."

Now that they were on the outskirts of the base, Lin Dong simply pulled Lin Weiliang out and said with a smile, "But the downside is that the motion model is much more complicated."

Additionally, this elastic component is a consumable item and needs to be replaced approximately every 2 to 5 kilometers, depending on usage intensity. The cost of replacement is around 800 yuan.

His mechanical dog design, in terms of both function and structure, was very different from the mainstream industrial mechanical dogs that came out more than a decade later.

The most significant difference is the addition of a waist-balancing mechanism and a waist-balancing motor, which improves the robot dog's flexibility and smoothness of movement.

Another feature is the addition of carbon fiber energy storage prostheses (running knives) similar to those used by disabled athletes to the limbs, a special type of carbon fiber elastic energy storage structure.

This structure can further improve the coordination and flexibility of the robot dog's movement, reduce noise from hard impacts on the ground, and at the same time significantly improve the robot dog's movement efficiency and endurance.

However, the downside is that the motion model becomes extremely complex...

Compared to a typical mechanical dog with a flat back and rigid four legs, the entire motion model is at least several hundred times more complex.

Each time it moves, the robotic dog must react within 10 milliseconds to various parameters, including the energy storage and rebound of its limbs, the coordination of its waist, its own center of gravity balance, the ground microenvironment, and air resistance.

The model and parameter tuning involved here require even Lin Dong a large amount of training data to adjust the entire model to be perfect.

But in Lin Dong's view, these two designs are necessary.

After all, system debugging wasn't too difficult for him; the only troublesome part was the training data, which could also be quickly resolved using money.

"good."

Xu Ziming watched Xu Qingling walking the electric dog ahead, looking quite happy, and nodded with satisfaction.

After saying that, seeing the apartment complex right in front of her, she turned to Lin Dong and said, "What are you still doing following along? Aren't you going home?"

"Um... I left my backpack on there."

Lin Dong pointed to the location of Xu Ziming's house: "We need to go up there to get our schoolbags."

"..."

Xu Ziming's expression froze for a moment, but he didn't say anything more: "Take it and go back quickly."

"it is good."

Lin Dong nodded.

But as soon as he finished speaking, the roar of a car engine sounded outside.

Wang Xingguo drove his Mengshi (Warrior) to a parking space on the side of the road in the community and got out, carrying a brown paper bag in his hand.

"Mr. Xu, I need to go to your house, there's something I need to discuss."

Wang Xingguo spoke naturally, while subtly giving Lin Dong a look.

"What's the rush?"

Xu Ziming was stunned. Looking at Wang Xingguo bringing the file bag to the door, he suddenly felt a strange sense of familiarity.

seemingly……

In early spring, after they returned from an outing, Wang Xingguo approached Lin Weiliang with a file folder in this manner...

"Let's talk about it up there."

Wang Xingguo pointed to the surrounding environment.

"All right."

Xu Ziming felt even more uneasy, but after thinking about it, he couldn't figure it out, so he could only nod and lead Wang Xingguo upstairs.

The group took the elevator up to their floor and stepped out. Xu Ziming had just opened the door.

Zhou Xiaoyan and Xu Qingling, who were looking for her mother, also came out from another elevator.

"Engineer Wang, Xiao Dong."

Zhou Xiaoyan clearly knew something from Xu Qingling. She greeted her politely, glanced at the file folder in Wang Xingguo's hand, and sighed softly before saying to Xu Qingling, "Lingling, go make some tea."

"Okay, Mom."

Xu Qingling gave Lin Dong a look, as if to say, "I've brought back reinforcements for you," and then went into the house first.

The group went into the living room and sat down. Xu Qingling brought out a pot of brewed tea, poured seven-tenths full of cups for everyone, turned on the fake listening device, drew the living room curtains, and obediently sat down next to Lin Dong.

"..."

When Xu Ziming saw Xu Qingling sitting next to Lin Dong like this, his eyelids twitched twice.

He then glanced at the file folder in Wang Xingguo's hand, then at Lin Dong, and finally said to Wang Xingguo in a deep voice, "Speak, kid, what is it that you want me to take the blame for this time?"

Xu Ziming is not stupid.

At first, Xu Qingling didn't realize anything when she called Zhou Xiaoyan back, and Wang Xingguo only sensed something was wrong when he came to the door.

But when he saw that Zhou Xiaoyan was not at all surprised when Wang Xingguo came to visit, it was clear that Xu Qingling had told him something beforehand, and he immediately understood.

To have one's precious daughter call Zhou Xiaoyan back early to keep things under control, and to have Wang Xingguo come to the door like this...

Aside from something related to Lin Dong, there's no other possibility that he'd be asked to take the blame.

"It's nothing serious."

Wang Xingguo picked up his teacup, took a sip, and looked at Zhou Xiaoyan, who had returned and was sitting next to Xu Ziming. In his heart, he gave Xu Qingling a thousand thumbs up.

As the Chengdu Aircraft Industry Group's 001, he knew Xu Ziming's detailed resume and had also heard about Xu Ziming and Zhou Xiaoyan's love story. He understood that with Zhou Xiaoyan present, this matter could definitely be resolved smoothly.

"Ziming is thirty-nine this year, and he'll be forty after his birthday soon..."

Wang Xingguo put down his teacup, took out a signed and stamped nomination recommendation letter, and placed it in front of Xu Ziming and Zhou Xiaoyan: "I think this is about ready to be used."

"The Academy of Engineering... hiss!"

Xu Ziming looked down, immediately gasped, and backed away: "Where are you planning to sell me?"

"Engineer Wang, this is too heavy. My son Ziming can't carry it."

Zhou Xiaoyan frowned as she looked at the nomination letter in front of her, then pushed it back, saying seriously, "You don't need to do this for Xiao Dong's sake. We will definitely help if we can."

"This is what Ziming deserves. I just followed the normal nomination process for his achievements."

Wang Xingguo smiled and took out the remaining documents from the file folder, placing them in front of Xu Ziming: "This achievement is enough for one spot."

"Third-generation single-crystal nickel-based materials..."

Xu Ziming glanced at it, then seemed to realize something, and suddenly looked up at Lin Dong: "You're the materials team that coordinated with 624 and 606 to provide experimental directions?"

"Uncle Xu, I did not cooperate with the dispatching of 624 and 606."

"But if it's someone who gives direction for the experimentation of third-generation single-crystal materials... that's me."

Lin Dong honestly replied, "But it's just me; I don't have a materials team."
