“He owns an inconspicuous vehicle, allowing him to blend easily into working-class areas. Those places are his natural hiding ground.

He harbors hatred toward women, stemming from childhood and adolescence when he likely received no affection from older female family members—possibly experiencing abuse and humiliation instead. This has left him unable to form normal relationships with women in adulthood.

The year-long gap between crimes suggests imprisonment, illness, or perhaps a relationship that temporarily halted his criminal behavior. But ultimately, he couldn’t find satisfaction and struck again.

He might have an accomplice, but if so, they would be weaker and subservient to him.

He’s the type of person we see every day in working-class neighborhoods—someone who wouldn’t draw attention even walking the streets at night. His criminal techniques aren’t necessarily sophisticated.

He has obsessive-compulsive tendencies. If you visited his shop or workplace, you’d find everything arranged with machine-like precision. He’s poor at communication, easily agitated, with strong violent tendencies.

That’s all I can deduce for now. I hope it helps with your investigation.”

After listening, You Mingxu instinctively glanced at the person beside her. Just as she was about to discuss the case further with Professor Fan, that head thrust itself into view, his handsome but foolish face suddenly occupying half the screen.

Yin Feng said, “Oh? Auntie, your deductions match mine.”

You Mingxu’s face darkened, but before she could push him away, Fan Shuhua’s eyes widened on screen: “Yin Feng?!”

Yin Feng simply took the phone from You Mingxu’s hands, asking curiously, “You know me?”

Fan Shuhua’s expression grew complex. She stared at him for a long while, then looked at You Mingxu, sighing, “Just a year without seeing you, and you don’t even recognize your teacher? I taught you criminal psychology—you don’t remember at all?”

You Mingxu was startled—they were teacher and student. Yin Feng thought for a moment, brought the phone closer to examine it carefully, then smiled slightly and nodded: “You do look somewhat familiar.”

Fan Shuhua’s expression became even more indescribable. After several seconds of silence, she asked, “I’ve been abroad all year, and only recently heard about what happened to him. Has he been like this the whole time?” This was directed at You Mingxu, who answered, “Yes. But I think he’s much better now than when it first happened.”

Yin Feng immediately glanced at her, then bit his lip, smiling secretly. You Mingxu casually patted his head, suggesting he should behave after being praised.

Fan Shuhua observed their little interactions, and despite being a renowned expert, felt the urge to widen her eyes again in surprise.

Heaven knew what a mature, experienced, and forceful man her star student had been before the incident. She hadn’t entirely approved of his personal life—not because of any character flaws, but because none of his relationships with women lasted long, always beginning and ending abruptly. From Fan Shuhua’s perspective, her brilliant student wasn’t interested in women; rather, he lacked trust in them, unable to open his heart.

But now, Yin Feng was like a teenager experiencing first love, his pure, rippling gaze giving Fan Shuhua goosebumps.

However, her student’s private life wasn’t her business, nor was it the crucial matter at hand. Fan Shuhua said thoughtfully, “Yin Feng, your teacher has some questions.”

You Mingxu understood, saying, “Professor Fan, I’ll leave you two to talk. I’m going back to my room for some water.”

Yin Feng protested: “I have water in my room, Ah Xu, I’ll get it for you.” He was about to drop the phone, but You Mingxu held his hand down, saying quietly, “Can’t take a hint? Stay put.” Then she left.

Yin Feng wasn’t stupid—he understood and raised the phone, staring straight at Fan Shuhua.

Fan Shuhua looked at his frog-like wide-eyed expression, unsure whether to laugh or feel heartbroken. Finally, she smiled gently and probed: “Yin Feng, you don’t remember anything from before?”

Blurred, chaotic images flashed through Yin Feng’s mind. He answered irritably, “Right, I don’t remember anything.”

After a moment’s silence, Fan Shuhua asked, “What about that person? The one you told me about before—you felt someone was secretly watching you, following you, someone who knew you very well and had sophisticated criminal methods.”

Yin Feng stared at Fan Shuhua for several seconds, asking, “Who was it?”

Fan Shuhua shook her head, her wise eyes showing traces of worry and confusion: “All I know is what you told me—initially, you spent over a month trying to track down this person’s existence but found nothing. The situation made you extremely anxious at the time. You believed they weren’t simply an obsessed fan or someone seeking revenge; you thought there was a massive conspiracy targeting you. You wanted my help analyzing it. But even I couldn’t figure anything out.

Later, after I went abroad, you called me saying you had a lead and wanted to meet in person to discuss it. But before we could meet you…”

Yin Feng said, “Teacher, that person hasn’t appeared again. I don’t want to look for them or investigate anymore. I’m very happy now, much happier than before.”

You Mingxu sat on her bed, wondering what Yin Feng might be discussing with his mentor, hoping the foolish boy wouldn’t upset his teacher. The thought made her smile.

Then she immediately sobered. Why was she grinning over him—was foolishness contagious?

Just then, her phone rang. It was Xu Mengshan.

“Sister You, we found something—Liu Yisha did borrow campus loans from Fenjinbao! The principal alone totaled around 100,000 yuan, with interest of over 300,000! There was no way she could ever repay that amount!”

—

Combined with Liu Yisha’s reconstructed phone records, messages, WeChat history, and bank accounts, her lending relationship with Fenjinbao Company became clear.

Starting from February this year, Liu Yisha borrowed from the company—amounts of 3,000 and 5,000 yuan. Later, she borrowed larger sums like 30,000. Police traced the money flow and found that early on, after keeping what she needed for daily expenses, Liu Yisha had sent most of these funds home—her father in the village had fallen while repairing the roof, breaking his leg, and urgently needed medical expenses.

In debt and approaching graduation, Liu Yisha had no job lined up and was increasingly financially strapped. She worked some part-time jobs, but the income was low. So she kept borrowing 2,000 or 3,000 yuan at a time. At graduation, needing money for rent while her father’s medical bills kept coming, she borrowed even more…

Three days before her disappearance, there were chat records with her Fenjinbao contact—”Brother Apple”—showing she’d asked to borrow 10,000 yuan. Brother Apple expressed reluctance, suggesting they meet to discuss. There was no further communication after that.
