Solving the case: Combining the police dog's olfactory genes at the beginning

Luo Fei pressed the communication button, and the voice was steady and clear.

A reply came through the radio from the control tower. The sound was slightly muffled by electrical interference, but the content was clear: "B-7788, taxiing is permitted. Use runway 14. Wind direction 090, wind speed 4 m/s, corrected sea pressure 1013."

Luo Fei pushed the accelerator lever.

The roar of the aircraft's engines suddenly rose, and the massive fuselage began to move slowly forward. The Gulfstream G650ER's taxiing was very smooth, and the sound of the tires rolling on the concrete was dull and rhythmic, like a large drum being repeatedly struck.

The indicator lights on both sides of the runway rushed past, the control tower in the distance grew closer and closer, and the color of the sky was reflected in the windshield—that clean and bright blue that is unique to near noon, without a single cloud.

The plane taxied to the starting point of runway 14, its nose facing the endless runway extension. At the end of the runway, the sea surface shimmered with a layer of fine golden light under the sunlight, and the white foam of the waves rose and fell in the deep blue water.

Luo Fei pushed the throttle lever to the maximum thrust position.

The engine roared to life.

The force pressed all three of them firmly into their seats. Zhao Zhenhai instinctively gripped the armrest, his knuckles turning slightly white from the pressure.

He had been flying for decades and was used to the feeling of being pushed back during takeoff, but sitting in the co-pilot's seat and watching someone flying a Gulfstream for the "first time" operate the aircraft was an experience more thrilling than riding a roller coaster.

The nose of the aircraft rose, the main landing gear left the ground, and the fuselage began to climb at a stable and standard angle of attack.

The cityscape of Haiwei City shrank rapidly outside the porthole, the dense buildings turning into piles of gray and white blocks, and the crisscrossing streets becoming lines as thin as silk threads.

The plane passed through a thin layer of clouds, and the outside of the window instantly turned into a white fog. Then the fog was suddenly thrown down, and the sunlight shone on the wings without any obstruction. The navigation lights on the edge of the wings blinked in the bright blue sky.

Zhao Zhenhai glanced down at the data on the instrument panel—climb rate, airspeed, heading, fuel consumption—every item was within the standard parameters, without the slightest deviation.

He glanced up at Luo Fei beside him and saw that Luo Fei's hands were firmly gripping the side lever and the accelerator, his gaze shifting between the dashboard and the view outside the porthole, his expression as calm as if he were driving an automatic family car.

Is this your first time flying?

Zhao Zhenhai couldn't help but ask again, his voice filled with undisguised shock.

"This is the first time I've flown this aircraft."

Luo Fei's tone was casual, "But the principle is similar."

Zhao Zhenhai opened his mouth, but ultimately swallowed back the words that were about to come out: "This isn't a matter of principle." He had flown over 10,000 hours and trained dozens of flight students, but he had never seen a student like this before.

To be precise, Luo Fei was not a trainee at all—from the moment he sat in the pilot's seat to the moment he completed the takeoff and climb, the whole process was smooth and efficient, with every step of the operation clean and crisp, without the slightest hesitation or unnecessary movement.

This level of proficiency and mental fortitude cannot be explained by a "newbie".

After flying for one hour and twenty minutes, a flashing green dot appeared on the destination radar.

The runway lights at Haiwei City Shuipo Airport are all on. From the air, the airport looks like a gray rectangle embedded in the green earth, with the runway as the central axis of the rectangle, guiding the direction of the aircraft's descent.

The approach lights on both sides of the runway flickered on and off, their white light appearing somewhat weak in the midday sun, but still clearly visible.

Luo Fei adjusted the flap angle and engine thrust, and the aircraft began to approach the runway at a smooth glide angle. Zhao Zhenhai sat in the co-pilot's seat, his hands on his knees, his fingers clenching and unclenching nervously.

He knew that landing was the most dangerous part of the entire flight, especially for inexperienced pilots. The slightest deviation in the glide angle, the influence of crosswinds, and the control of landing speed could all determine the outcome of the landing.

But Luo Fei's landing, just like his takeoff, was so precise that Zhao Zhenhai was speechless.

The moment the wheels touched the ground, Zhao Zhenhai felt only a very slight vibration, as if the carriage had run over a tiny crack.

The plane didn't bounce, didn't deviate from the runway centerline, and the braking intervention was perfectly timed, with all parameters at their optimal values. Even Zhao Zhenhai himself can't always achieve this level of landing.

He took a deep breath and turned to look at Luo Fei.

"That's a good drop."

Luo Fei did not respond, but simply taxied the plane to the designated parking spot on the tarmac and then shut down the engines. The roar of the engines went from high to low, finally turning into a faint metallic cooling sound, like the slow panting of a giant beast after vigorous exercise.

Lu Chuan walked from the passenger cabin into the cockpit, his face still a little pale, but the shock in his eyes had overshadowed his tension.

"The control tower said we can stop for two hours, and the refueling truck is already on its way."

"it is good."

After Lu Chuan got off the plane, he directed the refueling truck to come over. After the tanker truck came to a stop, ground crew members wearing orange reflective vests pulled out the refueling hose and, together with Lu Chuan, inserted the nozzle into the refueling port under the wing.

Aviation fuel, carrying a distinctive kerosene odor, was poured into the tank, and the numbers on the fuel gauge slowly climbed upwards. The entire process lasted nearly twenty minutes until the tank was completely full.

After refueling, Luo Fei looked outside the cabin and said to Zhao Zhenhai.

"You and Lü Chuan, get off the plane now."

Zhao Zhenhai was stunned for a moment, then his expression changed.

"Mr. Luo, you're not planning to fly alone, are you?"

"Correct."

"No, absolutely not."

Zhao Zhenhai raised his voice a few decibels, “The Gulfstream G650ER is designed to be piloted by a single person, but that is only when equipped with an onboard fully automated driving system.”

There are no alternative airports along your current flight path, weather conditions are unstable, and strong air currents over the ocean could appear at any time. Flying long distances alone is too risky. In case of an emergency, you won't even have anyone to lend a hand—”

Luo Fei turned his head, looked at him, and smiled slightly.

You'll find out in a minute.

Zhao Zhenhai was stunned by the composure and confidence in those words. He opened his mouth, wanting to say something more to persuade him, but looking into Luo Fei's eyes, all the words stuck in his throat.

There was an unsettling calm in those eyes, like someone who had seen through all the endings and had lost interest in the process.

Lu Chuan tugged at Zhao Zhenhai's sleeve and whispered, "Let's go."

The two turned and disembarked, their steps heavy as if filled with lead. At the bottom of the gangway, Lü Chuan stopped and glanced back at the cabin. Luo Fei walked to the cabin door, one hand on the frame, the other in his work uniform pocket.

His figure appeared exceptionally straight against the white fuselage, and the blue sky above him, like an inverted mirror, cast his shadow on the wing.

"Mr. Luo."

Lu Chuan suddenly spoke. "Hmm?"

"Could you... leave me your contact information?"

Lu Chuan's voice was a little tense, "In case—I mean in case—you come back, so I'll know."

Luo Fei remained silent for a second.

"Give me a cell phone."

Lu Chuan paused for a moment, then immediately pulled a brand new cell phone out of his pocket.

The phone's casing was made of dark gray metal, giving it a cool, solid feel in the hand. On the back was an octagonal camera module with a line of small, gold-stamped lettering below it. He handed the phone over, and Luo Fei caught it quickly and steadily.

"Huawei Starlink".

"This phone uses Huawei's own Starlink communication module, which works by using a low-orbit satellite constellation to achieve global signal coverage. It is a direct competitor to Musk's Starlink system."

Lu Chuan's tone carried a rare hint of pride, "It covers the entire Earth, whether it's the Pacific Ocean or the Sahara Desert, as long as you can see the sky, you have a signal."

Furthermore, it uses 128-bit quantum encryption technology, making it technically more secure than foreign methods.

Luo Fei looked down at the phone in his hand and flipped it over. The metal back cover reflected a soft luster in the sunlight, and the buttons on the side of the phone were neatly arranged, each with finely chamfered edges that felt smooth and comfortable to the touch.

Thanks.

He put his phone in his pocket, turned around, and walked back into the cabin.

Lu Chuan and Zhao Zhenhai stood on the tarmac, watching Luo Fei's figure disappear behind the cabin door. The door closed automatically with a muffled hiss of airlock. The gangway slowly retracted, disappearing into the bottom of the fuselage.

Zhao Zhenhai suddenly asked in a low voice.

"Lu Chuan, what did he just say he was going to Japan for?"

Lu Chuan's gaze was fixed on the white plane, and his lips moved slightly.

"Go avenge our brothers."

Zhao Zhenhai's pupils contracted slightly.

The plane began taxiing. The Gulfstream G650ER's nose was pointed at the runway, and the roar of its engines resumed, louder and more rapid than before. The heat waves from the wings distorted the air, blurring the outlines of distant buildings into indistinct curves.

The water stains remaining on the runway were splashed everywhere by the wake, and the water droplets evaporated into a cloud of white mist in the sunlight.

Lu Chuan and Zhao Zhenhai stood on the tarmac, watching the white plane get faster and faster, farther and farther away, and then the nose suddenly lifted up, and the whole plane, like a white arrow, pierced straight into the blue sky, climbing upwards at an astonishing speed.

The fuselage gleamed with a metallic sheen under the sunlight, and the golden phoenix emblem on the tail stood out against the blue sky, like a real phoenix spreading its wings and soaring high.

The airplane's silhouette grew smaller and smaller until it became a tiny dot of light in the deep blue sky.

Zhao Zhenhai looked up at the point of light, took a deep breath, and then turned to look at Lü Chuan.

The two exchanged a glance and simultaneously revealed a meaningful smile—a smile that contained both relief and an inexplicable expectation.

Lu Chuan turned his gaze away from the sky, took out his phone, dialed three numbers, and held the phone to his ear.

The call was answered after three rings.

"Hello, is this 110? I need to report a crime."

"Yes, someone stole a plane."

"Model number? Gulfstream G650ER, serial number B-7788."

"What did the person who stole the plane look like? He was probably over 1.8 meters tall, wearing an airport uniform and a blue baseball cap. He had an average appearance, the kind you wouldn't notice in a crowd."

Lu Chuan paused, looked up at the blue sky that was now completely obscured, and calmly added the last sentence.

"...He's a ruthless person."

Lu Chuan and Zhao Zhenhai stood on the tarmac, watching the Gulfstream G650ER disappear into the horizon, and remained silent for a long time.

Zhao Zhenhai spoke first, his voice a little dry: "Old Lü, what do we do now?"

"Do as Sister Jiang says."

Lu Chuan took out his phone, took a deep breath, and then dialed those three numbers.

The phone was answered in less than three rings, and a standard female voice came from the other end: "Hello, this is the 110 emergency service. How can I help you?"

Lu Chuan's voice suddenly trembled, carrying a kind of panic that was hard to tell whether it was nervousness or a deliberate attempt to create: "Hello, is this 110? I want to call the police!"

"Sir, please don't be anxious, tell me slowly, what happened?"

"An airplane! An airplane has been stolen!"

Lu Chuan's voice rose a few decibels, sounding as if he had just recovered from the shock, "It just happened at Shuipo Airport, that person took the plane away!"

"Sir, are you saying the plane has been hijacked? What is the model of the plane?"

"Gulfstream G650ER, serial number B-7788, white, with a gold phoenix emblem on the tail fin."

As Lü Chuan spoke, he winked at Zhao Zhenhai, who immediately understood and moved closer to the phone, his voice even more urgent than Lü Chuan's.

"I'm the captain of this plane! That man forced us off the plane with a knife, then just flew it away! He was incredibly strong; the two of us couldn't stop him at all!"

The operator on the other end of the line paused for a second, presumably to verify the authenticity of the call. Hijacking a plane is a top-level security incident in any country, and the operator dared not delay, immediately switching to emergency procedures.

"Sir, please describe the physical characteristics of the hijacker."

Lu Chuan cleared his throat, trying to make his voice sound more genuine: "Over 1.8 meters tall, slender figure, wearing a light blue airport uniform, and a blue baseball cap pulled low over his head. His appearance... very ordinary, broad cheekbones, square jaw, single eyelids, the kind you'd definitely not notice in a crowd, but—"

He paused, then emphasized, "But he was really strange. Those hands were like iron clamps; when they grabbed my arms, I couldn't move at all, and even though I was kicking my legs on the ground, I couldn't stand up."

Moreover, within three minutes of boarding the plane, he had mastered all the instruments and was even more skilled at piloting the aircraft than Lao Zhao. His takeoff, landing, and taxiing were all executed flawlessly, with no deviation whatsoever. (End of Chapter)
