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

"The perpetrator inserted his hand directly into the genitals, causing a rupture, and then hit the head with a stone. He was in intensive care for six hours and is now in the ICU. Doctors say he may become a vegetable."

The air in the office seemed to freeze.

Luo Fei felt a chilling rage creep up his spine, like a venomous snake coiling around his heart.

He hadn't originally planned to get involved in the case, since he was just an advisor and the captain had made it clear that he didn't need to get involved.

But at this moment, looking at the girl's pale face in the photo and the dark red bloodstain beneath her, he changed his mind.

"Huang Xiao".

Luo Fei suddenly stood up, the chair scraping against the floor with a screeching sound.

"Take me to see your captain."

Huang Xiao was taken aback.

"But the captain said..."

“I said, take me to see him.”

Luo Fei's voice was eerily calm, and his dark eyes held a light that Huang Xiao had never seen before.

Ten minutes later, in the criminal investigation team's office.

"Consultant Luo, I appreciate your enthusiasm, but we already have a special task force following up on this case."

Team leader Li Guoqiang sat behind his desk, his hands clasped on the table, his tone carrying an unquestionable authority.

Luo Fei stood by the window, the backlight obscuring his expression in shadow.

"Captain Li, have you found the killer in that similar case two months ago?"

Li Guoqiang's expression froze for a moment.

"Still under investigation."

In other words, no.

Luo Fei turned around, and the sunlight formed a silhouette behind him.

"Both cases involved young girls as victims, occurred in remote locations, and involved the same modus operandi. There was no sexual assault or robbery; it was purely torture for the sake of torture. These cases can be combined for prosecution."

Li Guoqiang frowned.

"We certainly considered merging the cases, but..."

"But what?"

Luo Fei took a step forward.

"But you've been investigating for months and still can't identify a single suspect?"

The atmosphere in the office instantly became tense.

Huang Xiao stood aside, watching the two confront each other with unease.

"Advisor Luo."

Li Guoqiang's face darkened.

“I understand how you feel, but solving cases isn’t about acting on impulse. We have our own procedures for handling cases.”

Luo Fei sneered.

"Procedure? The procedure is just to let yet another girl lie in the hospital waiting to die?"

"you!"

Li Guoqiang slammed his fist on the table and stood up abruptly, but Luo Fei had already turned and headed for the door.

"I'm determined to take on this case."

Luo Fei said without turning his head.

"Captain Li, you can choose to cooperate, or... watch me investigate myself."

The door was gently closed, leaving Li Guoqiang with a livid face and Huang Xiao with a bewildered expression.

In the corridor, Huang Xiao quickly caught up with Luo Fei.

"Advisor Luo, wait a minute!"

Luo Fei stopped and turned to look at her.

"What, are you trying to tell me to mind my own business?"

Huang Xiao bit his lower lip.

"No. I just... my father said you were very capable, but the captain..."

"Your father?"

Luo Fei raised an eyebrow.

"Huang Zhiming, a criminal investigation expert from the provincial department."

Huang Xiao straightened his back.

He said you have a special ability.

Luo Fei's lips curled up slightly.

"So, you believe I'm better able to solve this case than your captain?"

Huang Xiao hesitated for a moment.

“I don’t know. But what you just said is all correct, we really haven’t made any progress. On the day of the incident, all the cameras at the town’s entrances and exits were malfunctioning, and nearby residents didn’t see any suspicious vehicles. We’ve investigated seven or eight suspects, but they all have alibis.”

Luo Fei narrowed his eyes.

"The cameras are all broken? What a coincidence!"

"The technical department said the malfunction was caused by a system upgrade."

Huang Xiao's voice grew softer and softer, clearly indicating that she herself did not believe this explanation.

Luo Fei suddenly moved closer to Huang Xiao, so close that she could smell the faint scent of tobacco on him.

"Officer Huang, would you like to see my 'special ability'?"

Huang Xiao subconsciously took a half step back.

"What?"

Micro-expression analysis.

Luo Fei gave a mysterious smile.

"I can read your secrets from the changes in your facial expressions."

Huang Xiao frowned.

"This is impossible."

"Try?"

Luo Fei tilted his head.

"Just answer a few questions for me."

Huang Xiao nodded with some skepticism.

Luo Fei's gaze lingered on her face, from her slightly trembling eyelashes to her tightly pursed lips, and then to her Adam's apple bobbing with tension.

he asked suddenly.

What did you eat this morning?

"what?"

Huang Xiao was taken aback.

"Just bread and coffee."

Luo Fei nodded.

"You're lying. You didn't eat breakfast at all; you just drank a cup of black coffee with half a packet of sugar."

Huang Xiao's eyes widened.

"What are you doing"

"You have coffee stains on the corners of your mouth, but no food residue."

Luo Fei pointed to her collar.

"And you have a little sugar granule on your collar."

Huang Xiao subconsciously touched his collar, his face slightly flushed.

Luo Fei continued.

"Next question. What time did you go to bed last night?"

Around 11:30.

Huang Xiao answered very quickly this time.

Luo Fei smiled.

"You're lying again. You were still browsing your phone at 2:17 AM, looking at online shopping pages?"

Huang Xiao's face turned deathly pale instantly.

"This is impossible! You...you were spying on me?"

"Your eyes have slight bloodshot streaks, dark circles under your right eye, and slight marks left by your fingers swiping the screen."

Luo Fei shrugged.

"As for online shopping, when you asked what time you went to sleep, your right hand unconsciously touched your phone. That was a subconscious action when you remembered shopping last night."

Huang Xiao was so shocked that he couldn't speak.

Luo Fei took the opportunity to get closer and lower his voice.

"One last question. What color is your bra today?"

"what?!"

Huang Xiao's face flushed red, and he glared angrily at Luo Fei.

"This is too much!"

Luo Fei, however, remained calm.

"Just a test. Purple, with lace trim, bought last Sunday at 'Whisper' lingerie store for 368 yuan after the discount."

Huang Xiao was struck dumb, frozen in place.

She was indeed wearing purple underwear today, with a thick coat over it, so it was impossible for anyone to tell.

What's even more terrifying is that Luo Fei got the purchase location and price right!

"How could you?"

Huang Xiao's voice trembled.

Luo Fei smiled mysteriously. "Micro-expression analysis. When you heard the question just now, your pupils dilated, your breathing accelerated, and your left hand unconsciously touched your ribs. This is a physical reaction to thinking about underwear. As for the store and price…"

He pointed to Huang Xiao's bag.

“A corner of your shopping receipt is peeking out of your bag, and I can see the ‘Miyu’ logo and the number 368.”

Huang Xiao hurriedly checked his bag and found a small receipt sticking out from the edge.

But she clearly remembered putting the receipt at the very bottom of her wallet, how could it be...
Just then, Luo Fei's eyes suddenly became deep, and his pupils seemed to dilate.

Huang Xiao felt a wave of dizziness, and the scene before his eyes became blurry.

"Officer Huang."

Luo Fei's voice suddenly became unusually gentle.

"Give me your phone."

Huang Xiao nodded blankly, mechanically took out his phone from his pocket, unlocked it, and handed it to Luo Fei.

She felt like she was dreaming, her body light and airy, yet her mind was unusually clear. She just couldn't control her actions.

Luo Fei quickly added her on WeChat and then returned the phone to her.

When Huang Xiao regained consciousness, she found herself holding a cell phone in her hand, while Luo Fei was smiling at her.

How did you know my phone password?

Huang Xiao's eyes widened, his fingers gripping the phone so tightly that his knuckles turned white.

Luo Fei raised the corners of his mouth slightly, revealing a meaningful smile.

"Every time you unlock your phone, your thumb lingers on the '5' key for an extra 0.3 seconds, and your index finger twitches involuntarily three times. And..."

He deliberately dragged out the tone.

"When you enter your password, your right shoulder will drop slightly. This is a subconscious reaction when people enter familiar numbers."

Huang Xiao gasped, a chill running down his spine.

She instinctively hugged her arms tightly, as if that would protect her from being seen through.

"Scared?"

Luo Fei chuckled and turned to walk towards the police car.

"Let's go, let's go to the scene. Your little secret is nothing compared to the case we're investigating."

Huang Xiao bit his lower lip and quickly followed.

She secretly glanced at Luo Fei's profile. His sharply defined face showed no emotion, as if what he had just said was just casual conversation about the weather.

"You really figured out my password just by observing me?"

After getting in the car, Huang Xiao couldn't help but ask.

Luo Fei fastened his seatbelt and didn't look back.

"Otherwise what? Would I tell you I can read minds?"

He deliberately lowered his voice, and when he saw Huang Xiao's body tense up instantly, he couldn't help but laugh out loud.

"Just kidding, focus on driving."

Huang Xiao's knuckles turned white as he gripped the steering wheel, and he was distracted the entire way.

She kept recalling the movements she made when unlocking her phone, but she couldn't figure out how Luo Fei had cracked the six-digit password from those subtle actions.

"arrive."

Luo Fei's voice pulled her back to reality.

The first crime scene was located in an abandoned factory on the outskirts of the city.

Two months have passed, and the cordon has long been removed, leaving only the whistling sound of the wind blowing through the dilapidated factory buildings, like the weeping of wronged souls.

"The deceased was a 23-year-old woman whose throat was cut and who had seventeen stab wounds, but none of them were fatal."

Huang Xiao opened the case file, his voice unconsciously lowering.

"The forensic doctor determined that she died from excessive blood loss, and the whole process may have lasted for more than half an hour."

Luo Fei squatted down and gently ran his fingers over the dried bloodstains on the ground.

"The killer enjoyed the process."

He narrowed his eyes.

"Every cut avoids vital points, watching the prey slowly die."

"At the time, only a size 42 footprint was extracted, but it was impossible to determine whether it belonged to the murderer."

Huang Xiao added.

“The scene was cleaned up very well, with no fingerprints, no hair, and even the traces of the victim’s struggle were deliberately erased.”

Luo Fei stood up, closed his eyes, and took a deep breath.

Huang Xiao knew he was using that legendary "super sense of smell," but quickly shook his head.

"It's been too long, nothing has been left."

He frowned.

"Let's go check out the next scene."

The second crime scene was in the stairwell of an old apartment building.

The victim was a 19-year-old college student whose death was even more gruesome: his eyes were gouged out, his tongue was cut off, and a crooked "sin" character was carved on his chest.

“The character for ‘crime’ was written with such force that it was almost etched into the rib.”

Luo Fei stared at the photo and said.

"What message is the killer trying to convey?"

Huang Xiao shivered.

"The two cases were similar in method, but the second one was clearly more brutal."

Luo Fei did not answer. He tried to activate his super sense of smell again, but still found nothing.

As darkness fell, the two returned empty-handed.

When they returned to the police station, Captain Wang Hong was receiving a young girl.

The girl was about twenty years old, her hands clasped tightly on her knees, her knuckles white from the force.

"This is Xiao Peng; she has an important lead."

Wang Hong explained.

“She was also attacked a few days before the first murder.”

Luo Fei and Huang Xiao exchanged a glance and immediately sat down.

"That day I was getting off work and it was getting dark when I got home."

Xiao Peng's voice trembled.

"Someone grabbed my neck from behind and I struggled desperately, but he was very strong."

"how does he look like?"

Luo Fei asked softly.

Xiao Peng shook his head.

"I couldn't see clearly. It was too dark, and I was scared."

She suddenly grabbed her left arm.

"He bit me here last time, and then ran away."

Huang Xiao immediately noted down this detail.

"Biting marks? The forensic examiner found similar biting marks on both bodies!"

Wang Hong's eyes lit up.

Can you describe his height and build?

"About half a head taller than me."

Xiao Peng gestured.

"I'm 163cm tall, and he's probably around 175cm. He's very strong; I couldn't push him. He's probably in his early twenties."

Wang Hong immediately arranged for a portrait artist to come and assist.

However, a few hours later, the portrait artist and his mentor, Lin Yonghui, the retired policeman known as the "magic brush," both walked out of the interrogation room dejectedly.

"The information is too vague."

Lin Yonghui shook his head and sighed.

"She can only remember a general outline, and can't even describe the facial features clearly."

Luo Fei leaned against the wall, looking at their dejected expressions, when suddenly, a mechanical voice rang in his mind.

[Ding! Congratulations, host, for successfully solving the case of the corpse hidden in the freezer and the Red Line Media fraud case, gaining 2850 sin points!]

Luo Fei tapped his fingers lightly on the table, when a sudden flash of inspiration struck him: the [Super Painting] skill in the system shop.

Since acquiring the "Sin Value System," he hasn't had the chance to use those special skills, and now might be the perfect time.

"Huang Xiao".

Luo Fei suddenly turned his head, a confident smile curving his lips.

"I want to try simulated portraiture."

Huang Xiao's hand, which was tidying up the documents, suddenly stopped. When he looked up, his eyebrows almost flew off his hairline.

"You? A painter?"

She looked Luo Fei up and down as if he had just announced that he was going to go to the moon.

"When did you learn to draw? I didn't know that."

Other colleagues in the office also cast curious glances their way.

Luo Fei laughed and deliberately tossed his hair exaggeratedly.

"I'm brimming with artistic talent, I just keep a low profile most of the time."

Huang Xiao rolled his eyes.

"Come on, forensic portraiture and regular drawing are completely different things. It requires a professional understanding of human facial structure, muscle direction, and facial expression changes, as well as the ability to guide witnesses to recall details through language."

She counted on her fingers.

"Not to mention, one must also have extremely strong observational skills and spatial imagination."

Just as Luo Fei was about to respond, a cold, stern voice came from behind him. (End of Chapter)
