Genius is just the threshold for me!

Rumbling--

An airport in the southwest.

The afternoon sun slanted down, turning the concrete track a golden hue. At the end of the track, sparse patches of withered grass swayed in the cold wind, rustling softly.

Wang Xingguo hid in a sheltered spot at the airport, watching military planes land in the sky.

A few minutes later, the military aircraft came to a stop, and ground crew immediately sent over the connecting ladder.

After waiting for a while, the hatch opened.

A woman with shoulder-length short hair, wearing glasses, standing a little over 1.6 meters tall, with a gentle and kind face, and a scarf around her neck, who looked to be in her forties, appeared at the cabin door.

The cold wind blew the ends of her scarf, and she raised her hand to pull it tighter. Behind her glasses, her eyes revealed the weariness of a long flight.

"Ruohua, over here!"

Upon seeing the figure, Wang Xingguo immediately waved and shouted, while running over at the same time.

Su Ruohua had just stepped off the plane and was walking towards a house not far away when she heard the sound and paused for a moment.

Turning his head, he saw a figure running over from the side and a smile appeared on his face. When Wang Xingguo walked to the side, he asked, "Why did you come over to pick me up in the middle of winter? Aren't you afraid of the cold?"

"Winter in Chengdu is much warmer than in the Northwest."

As Wang Xingguo spoke, looking at the figure he hadn't seen for several years, he suddenly opened his arms and gave him a big hug.

"Why--"

Su Ruohua exclaimed in surprise, struggled a couple of times, and shouted, "How old are you? Aren't you ashamed... with so many young comrades around watching?"

"You two chat, sirs. We'll be leaving now."

Several ground staff members nearby covered their mouths and chuckled, then bowed and quickly left the scene.

The military aircraft not far away also closed its cabin door, accelerated forward, turned, and then roared into the sky.

The roar of the engine faded into the distance, eventually becoming a blurry black dot on the horizon.

"alright."

Su Ruohua hugged him for a while, then let go, looking at Wang Xingguo's sparse hair and smiling, "You still have hair, you're not bald."

"We managed to catch our breath a few months ago and salvage some of our assets," Wang Xingguo said with a sigh, then gestured, "Let's go back now."

"What's the matter that you called me back in such a hurry?"

Su Ruohua took Wang Xingguo's arm and asked curiously, "Chengfei is going to build a space fighter, and they're going to study reentry trajectory control?"

"We'll discuss the details once we get on the bus."

"This matter is rather urgent, but it doesn't fall under Chengdu Aircraft Industry Group's business yet. I'm wondering whether I should take it on."

Wang Xingguo pointed to the Mengshi, which had been in his sight and had just undergone a thorough inspection today.

The black body reflected the sunlight, revealing its sharp lines. The windows were covered with privacy film, and the all-black exterior made it impossible to see anything inside.

Xie Qiming made two phone calls today to inquire about the joint research and development team, and he hasn't given a definite reply to the email yet.

Even though Su Ruohua had agreed to come back for this project, he thought about it all night yesterday and still kept wondering whether he should turn it down.

Because he knew that once this kind of thing started, it would become uncontrollable, just like the hot and spicy food incident, just like him, Lin Weiliang, Xu Ziming and the others.

When all sorts of problems related to aerospace, ballistic reentry, and space trajectory control come crashing down, coupled with Lin Dong's monstrous talent, Su Ruohua really doesn't know if she can withstand it.

But seeing the words "anti-ship ballistic missile" that Xie Qiming sent later, he just couldn't bring himself to back out.

Because he knew that Chengdu Aircraft Industry Group already had high-performance reconnaissance aircraft.

He understood what a high-performance reconnaissance aircraft combined with anti-ship missiles meant.

This means that the anti-ship missile can be deployed a day earlier, and the country can breathe a sigh of relief a day earlier under the blockade and pressure from the other side.

"I thought Chengdu Aircraft Industry Group was going to build an aerospace fighter jet."

Su Ruohua understood the hidden meaning in Wang Xingguo's words and turned her head to ask, "It would be very tiring for me to help with this, but it would be of great help to the country?"

"Mm." Wang Xingguo nodded.

"I guessed that was it. There are only two things that could make you so conflicted. If there were only one, you would have already decided to either refuse or accept it."

Su Ruohua smiled and naturally intertwined her fingers with Wang Xingguo's hand: "If that's the case, then let's agree."

"It's tiring, but Xiao Rui is on the same path now. If we're tired now, he'll have an easier time later."

"Alright."

Wang Xingguo paused for a moment and nodded, then tightened his grip slightly, the warmth of their palms passing through each other's hands.

"I called my teacher on Teacher's Day this year, and he told me he was working at Chengdu Aircraft Industry Group. And you tricked him once?"

Su Ruohua smiled, then suddenly remembered something and asked curiously, "What's going on?"

"How could I dare to cheat him?"

Wang Xingguo protested, "It's clearly this old guy's stubborn temper. No matter how I tried to persuade him, he wouldn't listen. He insisted on making trouble for himself and then blamed me."

"Still calling him an old man..."

Su Ruohua pinched Wang Xingguo and said helplessly, "You two are both over fifty years old. One of you is the chief engineer of the 611 Institute, which works on aircraft, and the other is the chief engineer of the 624 Institute, which works on aero engines. You are both in Sichuan in the southwest and have a cooperative relationship. Why are you still bickering like this?"

"Don't hold grudges."

Wang Xingguo nodded: "When I see him later, I'll call him Teacher Jiao."

"You'll keep calling me 'old man' when I'm not home, right?"

"No way... We don't argue. I always call him Engineer Jiao, and I even give him gifts every year during holidays," Wang Xingguo retorted.

As he spoke, he walked to the side of the car, opened the door, and beckoned Su Ruohua to get in. He then followed her in and turned on the anti-eavesdropping device and electromagnetic shielding device.

With a thud.

The car door closed, instantly isolating all external sounds, leaving only the faint hum of the instruments inside the car.

Wang Xingguo adjusted the power windshield to an opaque black, turned on the interior lights, and took a document from the armrest box, handing it to Su Ruohua.

"Ruohua, this is a control scheme for an anti-ship missile to re-enter the atmosphere and lock onto and pursue its target... What do you think?"

"Anti-ship missile re-entering the atmosphere?"

Su Ruohua adjusted her glasses, picked up the document, and began to carefully examine it.

She read some documents quickly, and others slowly, her fingers moving habitually as she read, her whole being focused on analyzing and verifying the control parameters.

"That's amazing..."

Ten minutes later, Su Ruohua casually turned the document over and put it down. She looked up at Wang Xingguo with a surprised expression and said, "The person who wrote this control model has a very thorough understanding of the ballistic reentry trajectory."

I now know that in the field of ballistic reentry control, there are probably only three people who can achieve this level of precision, but their algorithm models are not as simple and efficient as this...

The algorithm model here only requires them to control about one-third of the model's data... This means the entire control response cycle will be much faster.

During the brief window of reentry from space, the missile tracking system can gain approximately 2 to 5 seconds more time to lock on and control the missile.

"How about gaining another 2 to 5 seconds to lock down and control the situation?"

Wang Xingguo's eyes widened, and he couldn't help but curse, "Pervert!"

Although he did not understand ballistic missile control, he did understand that ballistic missile space reentry control is a very demanding technology.

Because the missile has entered the terminal phase of its flight path when it re-enters the atmosphere, the entire missile has undergone acceleration in the middle stage. Combined with the acceleration due to Earth's gravity, the fastest speed is already above Mach 20, and the slowest speed will reach Mach 10.

At this point, the entire journey from the 100-kilometer-high Carmen Line in space takes only 15 to 30 seconds.

But now.

A single control technique can buy an extra 2 to 5 seconds...

If this time is used well, the accuracy of the missile can be improved by at least one or two levels, or the survivability can be greatly improved by using terminal maneuvering technology.

"This control technology should be kept strictly confidential..."

Su Ruohua looked at Wang Xingguo: "Why did you take it outside? And when did Chengdu Aircraft Industry Group (CAC) have such an expert?"

"I see these things every day. Chengdu Aircraft Industry Group's top-secret storage facility is already full. Now we're hiding them in plain sight, not being overly secretive or making a fuss about them. This way, the secrecy is better and they attract less attention."

Wang Xingguo leaned back in his seat, took a deep breath, and said, "As for that expert... your godson."

"My son, Xiao Rui..."

Su Ruohua was stunned for a moment, then her eyes widened: "Wait! Godson? The Xiao Dong you mentioned last time?"

"right."

Wang Xingguo nodded and briefly recounted the situation during this period.

"Code name, Hope..."

Su Ruohua read the code name aloud.

But the next second, she stared wide-eyed at Wang Xingguo: "So, all these project titles you've suddenly acquired lately are thanks to Xiao Dong? You're taking credit for someone else's work?"

"You think I want to stand up? Look at my hair..."

Wang Xingguo was speechless: "He was only 8 years old when he showed his talent, designed a supersonic aircraft on his own, and shot down a J-20 when he was only 12 years old..."

"This...is indeed too much of a genius; he shouldn't reveal himself easily." Su Ruohua nodded understandingly.

As a professional, although not in the aviation field.

But she also knew what kind of talent it took to design a supersonic aircraft on her own at the age of twelve.

"Not just a genius, he's a prodigy."

Wang Xingguo emphasized this earnestly from the side.

They watched Lin Dong grow up.

If Lin Dong was just a super genius at the beginning, it took him two and a half years to learn how to design a supersonic aircraft.

However, as Lin Dong accumulated more and more knowledge through learning, the effects of his talent became increasingly extraordinary.

It takes less than six months to develop a hypersonic aircraft now.

The chief engineer of the top-tier company said that a medium-sized strategic reconnaissance aircraft only takes four months to complete.

This has completely transformed into a monster, and a super monster at that.

"So, that's why you were in such a hurry to call me back..."

Su Ruohua pointed to the documents she had casually turned face down, and said thoughtfully, "Covering up for Xiao Dong?"

"right."

After all, as you said, this technique can gain an extra 2 to 5 seconds of control time during the brief reentry window.

Then other ballistic missiles, and even intercontinental ballistic missiles, will most likely come knocking, needing to make improvements and adaptations based on this technology…”

After Wang Xingguo finished speaking, the car fell silent for a brief moment.

The couple exchanged a glance, and both saw silence in their eyes.

"Let's drive back."

"You've already brought the documents over and shown them to me, so I can't leave now."

After a long while, Su Ruohua rubbed her temples, took a deep breath, and said, "Let me see the child and ask about the situation before we talk."
