Siheyuan: At the beginning, I can integrate everything!

"If only I could use Advisor Zhang's name to write an article praising the child prodigy and publish it in the school newspaper..."

"Then isn't the 'Outstanding Teacher' award a sure thing?"

Yan Bugui found it increasingly wonderful.

It's as if I can already see the approval document for the wage increase and the adoring looks in the eyes of the three aunties.

Just as he was about to muster up the courage to knock on the door of the east wing.

Suddenly, a sharp braking sound came from the alley entrance.

"squeak--!"

Immediately following, an old man with gray hair wearing a white coat appeared.

Without even putting on a coat, he jumped out of the jeep in a flurry and headed straight for the courtyard house.

Yan Bugui was startled and quickly shrank behind the door.

Upon closer inspection, he noticed two conspicuous patches on the old man's clothes.

Who is this guy? He's acting like such a big shot, and the guards didn't even stop him?

Old Chen didn't even notice Yan Bugui behind the door.

He jogged all the way, panting, and rushed to the door of the east wing.

"Captain Chen, is Huaimin here?"

Old Chen wiped the sweat from his forehead, his voice revealing anxiety.

Upon seeing this leading figure in the scientific community, Chen Bing quickly stood at attention, saluted, and pushed open the door.

"Hey Mr. Chen, Consultant Zhang just woke up from his lunch break."

Inside the main room of the east wing.

Zhang Huaimin was sitting cross-legged on the heated kang (a traditional Chinese bed-stove), holding a Rubik's Cube in his hand.

His fingers flew across the keys, clicking away, and in a few quick movements, all six sides were the same color.

"Grandpa Chen, what brings you here?"

Zhang Huaimin looked up at Old Chen, who was panting heavily, with some surprise.

Since the last time we solved the problems of single-crystal alloys and super batteries in the top-secret research institute.

Old Chen treated Zhang Huaimin as a treasure even more than his own grandson.

"Huaimin, I'm in big trouble!"

Old Chen didn't bother with formalities and picked up the large tea mug on the table.

He gulped down a large mouthful of cool boiled water.

"Sigh, these past few days, our aerospace department has been holding meetings every day, and they're arguing non-stop."

Old Chen put down his teacup, plopped down in his chair, and let out a long sigh.

His weathered face was filled with deep worry.

"What's wrong? Is there a problem with the new engine?" Zhang Huaimin put down the Rubik's Cube.

"The engine is great! The performance is simply incredible!"

When the engine was mentioned, a glint of fervor flashed in Old Chen's eyes, but it quickly dimmed again.

"The problem lies with the radar."

Old Chen frowned and drew circles on the table with his finger.

"Western countries' radar technology is too advanced now."

"As soon as our planes take off, they appear as a giant fireball on their radar screens, clearly visible."

"No matter how fast or how high our planes fly, they can't escape their eyes."

Old Chen clenched his fists, his knuckles turning white, and his tone revealed a sense of frustration.

"It's like we've mastered unparalleled martial arts skills."

"But as soon as we went out, we would carry a large megaphone to tell the enemy where we were."

"How can we possibly fight this battle?"

Chen Bing, who was standing to the side, also looked solemn upon hearing this.

As a special forces soldier, he knew all too well the importance of air superiority and stealth.

In modern warfare, detection equals destruction.

Without stealth capabilities, even the best aircraft is just a sitting duck.

"So, I was put in charge of leading the research on radar stealth materials."

Old Chen shook his head with a wry smile.

"However, materials science has encountered a major bottleneck."

"We tried hundreds of radar-absorbing coating formulas, but they were either too heavy and affected flight, or the radar-absorbing frequency band was too narrow and could not defend against the latest microwave radar at all."

Old Chen raised his head, his hopeful old eyes fixed on Zhang Huaimin.

"Huaimin, Grandpa heard from Chief Lin that your mind is full of amazing technology that is ahead of its time."

"Do you...do you have any ideas?"

Looking at Old Chen's anxious and expectant eyes.

Zhang Huaimin remained silent.

He simply stood up and walked to the coat rack next to him.

He casually pulled off the blue cotton-padded jacket he usually wore.

This little cotton-padded jacket looks ordinary on the surface, and some parts are even faded from washing.

But at the collar of this cotton-padded jacket.

She wore a small, inconspicuous black metal hair clip.

That very night, Zhang Huaimin used the "miniature super acoustic radar" to monitor the entire steel rolling mill.

On the surface of the radar, Zhang Huaimin was already inside the system.

It also incorporates a layer of [full-band quantum wave-absorbing stealth coating].

It was originally intended to prevent being tracked by enemy agents using advanced equipment.

Now it seems it has come in very handy.

"Grandpa Chen, the invisibility materials aren't actually that complicated."

Zhang Huaimin picked up the little cotton-padded jacket.

With a "snap".

It was thrown directly at Old Chen's puzzled face.

"Put this over your head."

Zhang Huaimin pointed to Old Chen, who was covered by a cotton-padded coat.

"Brother Chen, take out your portable radar detector and scan Grandpa Chen."

Old Chen pulled his cotton-padded coat off his face, completely bewildered.

"Huaimin, what are you doing?"

"Putting a tattered cotton-padded coat over my head will protect me from radar? That's utter nonsense."

Old Chen was somewhat displeased, feeling that Zhang Huaimin was joking.

Chen Bing, who was standing to the side, was also stunned.

But he had blind trust in Zhang Huaimin.

Without saying a word, he pulled out a palm-sized, high-precision handheld microwave radar detector, the latest issued by the military region, from the inner pocket of his military overcoat.

"Mr. Chen, please forgive me."

Chen Bing turned on the detector.

"Beep—beep—"

The detector emitted a regular scanning sound.

On the screen, a red dot representing a high heat source and metal reflection waves flashed clearly.

The target was Old Chen, who was sitting in the chair.

"See? It's perfectly clear what use this tattered cotton-padded coat can be."

Old Chen shook his head, just about to put down his cotton-padded coat.

"Grandpa Chen, stick that black hair clip from the collar of your cotton-padded jacket to your chest."

Zhang Huaimin offered a casual reminder.

Old Chen frowned, finding it absurd, but he still did as instructed.

He pressed the unassuming black hair clip close to his chest.

Just as the hair clip was about to touch her.

Old Chen didn't even sense any energy fluctuations.

however.

"Beep—beep—"

The high-precision radar detector in Chen Bing's hand suddenly stopped working!

Chen Bing stared wide-eyed at the screen in his hand.

"This...how is this possible?!"

Chen Bing gasped in shock, his voice cracking.

The red dot that had been clearly flashing just moments before was now visible on the screen.

Vanished into thin air!

Clean and spotless, without leaving a single trace!

"What happened? Is the equipment broken?"

Hearing Chen Bing's exclamation, Old Chen quickly went over to see what was happening.

When he saw that blank screen.

This well-traveled and knowledgeable scientific giant felt his heart skip a beat.

He snatched the detector and scanned himself with it.

No!

There's absolutely no signal!

On this radar detector, which represented the highest level of technology in the country at the time.

He was Old Chen, a living, breathing man weighing over 100 pounds.

It has completely "disappeared"!

Even the heat radiation signals from his body were perfectly absorbed and shielded!

"My God..."

Old Chen gasped, nearly dropping the detector in his hand.

His hands trembled as he touched the black metal hair clip.

His eyes blazed with a light a hundred times more fervent than the discovery of a new continent.

"What...what kind of coating is this?!"

"Full-band absorption?! Nearly zero mass?!"

This completely overturned his decades-long understanding of physics!

If this coating could be applied to aircraft.

Those Chinese fighter jets will become true ghosts in the sky!

The elaborate traps set by Western countries are no match for a hair clip that a five-year-old child casually pulls out.

That's an absolute joke!

"Huaimin! Where...where did you get this divine object?!"

Old Chen was so excited that he trembled all over, and his old face turned bright red.

Zhang Huaimin yawned and sat back down on the kang (a heated brick bed).

"It's just a matter of using some scrap graphite and titanium alloy powder from the lab and reorganizing the molecular structure under high temperature and pressure."

"I wrote the recipe on a piece of scrap paper, it's in the drawer."

Zhang Huaimin pointed to the table next to him.

"Grandpa Chen, you can take it and see for yourself."

Following Zhang Huaimin's finger, Old Chen saw a crumpled piece of draft paper in the drawer.

He pounced like a starving wolf.

I carefully unfolded the paper.

I only glanced at it.

Old Chen stood there, completely stunned, as if struck by lightning.

"Perfect...absolutely perfect!"

"This molecular arrangement is simply a masterpiece of God!"

Old Chen was so excited that tears almost fell from his eyes.

He grabbed the dusty cotton-padded jacket and the draft paper and hugged them tightly to his chest.

He even gave up his military overcoat that was hanging on the chair.

"Huaimin! You are truly a living god of the nation!"

Old Chen shouted incoherently.

He turned around, like a madman, clutching his cotton-padded coat.

He sprinted out of the courtyard house at top speed.

"Quick! Prepare the car! To Top Secret Airport Number One!"
