I don't know why, after coming into contact with Chen Peng in the past few days, I always feel that my brain is very messy, and there always seem to be some indelible voices echoing in my mind.

Some of these sounds are fleeting and difficult to catch, while others are faintly painful but cannot be distinguished. Sometimes I really start to wonder if I'm fit to be a criminal psychology counselor.

I was so confused by the frustration of being confronted with criminals that I began to wonder if I could be a good police officer.

Especially after hearing some of Chen Peng's words, a trace of recognition of him flashed in my heart. But that doesn't mean I think he's right to kill, it's just that some of his views, at least in my current opinion, are somewhat convincing.

In particular, his attainments in criminal psychology and his analysis of human nature are incomparable to me.

Looking out the window at the moonlight gradually rising, leaning against the window, watching the shadows of the trees, listening to the wind driving the dance of the leaves, I really wanted to just stay still, not to think about the headaches that gave me a headache, but the stinging pain of the smoke across the throat, like a sharp knife cutting my throat, pulled me back to reality.

People have bad roots, I know!

But I don't know how this bad root of human nature can sink a person!

At least until now, I have not been able to shake off my own bad roots......

******

Nian Yu kept rubbing the ballpoint pen in his hand, but he couldn't write a word on the conversation record.

"You don't have to worry so much about whether the couple should die or not, deep down in everyone's heart there is a dark side that needs to be released, but there are big and small differences. I'm just magnifying the dark side of their hearts. Chen Peng sat opposite Nian Yu and said in a calm tone.

"You could have persuaded them to turn themselves in, why did you guide them to dissect and throw away their bodies?" Nian Yu's eyes were bloodshot, and his voice was hoarse when he spoke.

"I just magnified the dark side of their hearts, and even if I didn't, wouldn't they have sinned? Isn't it a crime that they killed that person without hesitation? Chen Peng asked rhetorically.

"They are defending themselves, and they are not at fault in the face of other people's robbery." Nian Yu looked at Chen Peng and argued.

"Killing is killing, don't be so high-sounding about the reason. If they don't have those dark desires in their hearts, will they pick up the knife and kill people? This desire is not only for them, but also for each of us, don't you suddenly have an urge to kill someone from the bottom of your heart at some point? Don't tell me you don't, you're an ordinary person. You also have the bad roots of people, and this is a fact that you can't get rid of. Chen Peng continued.

"I ......" After hearing Chen Peng's words, Nian Yu fell into a short period of contemplation.

Oh, yes! Sometimes, there will be a lot of dark thoughts bursting out in our hearts, and some people will take these sudden thoughts as a sign of being dizzy when they are extremely angry, and they will feel that this idea is not right, it should be contained, and this is the normal reaction of most of us.

However, some people will turn these ideas from the bad roots of human nature into action and implement them, and many people who do unforgivable acts just because of impulse, most of them do not restrain themselves well, and let the darkest things in human nature expand wantonly.

Nian Yu quickly weighed Chen Peng's words in his mind, trying to find a reason to refute Chen Peng, but three years ago, as a student of Chen Peng, Nian Yu did not do this. Today, Nian Yu interrogated the criminal Chen Peng as a police officer, and he did the same.

"Nianyu, in fact, I was very optimistic about you a few years ago. Not only do you have a keen sense of observation, but you also have strong analytical skills, and you will not let go of any questions and details in my class, and you can be regarded as the best among all the students I have taught. Chen Peng leaned back in the interrogation chair, his fingers gently rubbing the handcuffs, but his eyes were fixed on Nian Yu.

"This one doesn't seem to be related to what we're talking about today." Nian Yu said expressionlessly.

"Huh...... Aren't you trying to dissect my criminal motives and inner world? Then I'll tell you how to dissect other people's inner worlds. Why don't we first dissect and analyze yours? Chen Peng slowly sat up straight, and a very excited look flashed in his eyes.

Without waiting for Nian Yu to answer, Chen Peng began to continue: "Nian Yu, although you are one of the best students I have taught, you also have your weaknesses, that is, your impatience, indecisive personality and your ability to adapt to the consequences. ”

Nian Yu didn't speak, just stared at Chen Peng quietly.

"These weaknesses are not for many ordinary people, but for those of us who study criminal psychology, sometimes they are very fatal weaknesses." Chen Peng said to Nian Yu just like he did in the university class.

And Nian Yu seems to have returned to the class of his college days in a trance, facing one of his favorite teachers and listening to him talk about the things that attracted him.

"Who the hell is this guy?" Gu Yu stood behind the single transparent glass next door, looking at Nian Yu and Chen Peng, he didn't seem to have figured out what the relationship between the two was.

In Gu Yu's opinion, when the prisoner who was arranged by Chen Liao and Nian Yu to interrogate him today, he had been speculating about Chen Fatzi's thoughts, and wanted to find the most beneficial benefits for himself from the relationship between Chen Fatzi and Nian Yu, and getting closer to himself and Chen Fatzi through Nian Yu was Gu Yu's original idea.

But Gu Yu looked down on Nian Yu in his heart, and was even a little jealous of the care Nian Yu received from Fat Chen, these cares or nepotism in Gu Yu's opinion were things he wanted to get but never got it.

And when Gu Yu saw this legendary perverted serial murderer at first glance, he didn't feel the slightest fear, maybe it was Chen Peng's elegant appearance and his elegant manners that made Gu Yu's first impression of Chen Peng not so bad.

Although Chen Peng was firmly locked in the interrogation chair at this moment, his faint smile and magnetic voice made Gu Yu feel that this person did not seem to be a prisoner of Beijiang Prison, but an ordinary person who was chatting with Nian Yu about family life, but in this special environment, Gu Yu was still used to maintaining that condescending scrutiny of Chen Peng.

"But these are not the issues to be discussed today, I want to know today why you killed those eleven people, and the criminal motives you used to kill them, and the truest thoughts in your heart, instead of asking you to dissect my character weaknesses and inner world here." Nian Yu's forehead slowly oozed sweat, the back of the police uniform was already wet, he gritted his teeth and tried to calm his mood, allowing himself to come out of the trance just now.

"I'll just say you're one of the best people I've ever taught, and this inner hint and guidance doesn't seem to work much for you, haha...... Well, I'll tell you how the first man died, but it's still the same request, and you're going to give me your thoughts tomorrow. Loopholes, motives, whatever, I want to hear your thoughts. ”

Chen Peng sat in the interrogation chair with a smile on his face, and he had never been changed in the slightest by Nian Yu and his questioning, and he didn't even care about Nian Yu's embarrassment when facing him. Just where he said what he wanted to say, looking at what he wanted to see, it seemed that in this special interrogation room, he was the master who dominated everything, and Nian Yu was just the guest he invited to talk to him.

"With all that said, can you say it now?" Nian Yu still asked a little urgently.

******

Three years ago.

A female college student who has just graduated from Bac Giang University and is about to settle in Bac Giang City is looking for a small room that suits her by herself with a small advertisement for a street share house.

But after looking for a few days, I didn't find a rental house that suited me now. There is not much money in her pocket, and there is still a week before the time to go to the company for an interview, and she can't live in a small hotel near the school all the time, and such a high consumption is not something that she, an orphan who has completed college with scholarships and relief funds, can afford.

One evening after the rain, Ma Ling walked out of the small hotel next to Beijiang University in the dazzling red sunset, she had to find a place to live today no matter what, otherwise she would not be able to last until the first month's salary, although she is also doing some online part-time jobs these days, but this meager income does not seem to allow her to last longer.

Just when Ma Ling was at a loss, a small advertisement for a share house posted at the back door of Bac Gang University caught her eye.

This is a two-bedroom apartment seeking to share an advertisement, the price is within the acceptable range of Ma Ling, the location is in a community not far from Bac Giang University, from the content of the advertisement, it seems that the basic facilities of this room are not bad, the most important thing is that the price is not high, within the range that Ma Ling can afford.

Ma Ling dialed the homeowner's phone without hesitation, and it happened that the homeowner was at home at this time, and she couldn't wait to book with the homeowner to go over to see the house now.

In the afterglow, a girl with a ponytail and an old school uniform that many high school students would dislike hums a little song from her hometown, walking briskly towards the life she longs for.

This is a girl with a beautiful face, a pair of smart big eyes, not tall, and a thinner body. When Ma Ling was very young, her father left her forever because of a mining accident, and a few years later, her mother abandoned Ma Ling and her frail grandmother because she couldn't bear the poverty of her family, and she left alone and never heard from her again.

Since then, Ma Ling and his grandmother have relied on each other for many years, and have been relying on the help of the village to live. On the day when Ma Ling's admission notice to Beijiang University was delivered to her, her grandmother passed away with tears of relief, and the whole village helped Ma Ling send her grandmother away, and even raised money to send Ma Ling to the university classroom.

From the day Ma Ling walked out of the village, she secretly told herself that if she couldn't return to the village with her eyebrows raised, then she would not return to this small place where she was born and raised. Although there are many people here who have helped her, there are also many people who have laughed at her.

Ma Ling has lived under the ridicule of her peers since she was a child, she doesn't want to let herself go back to that past, although she is one of the few college students in the village, but she has not received the same treatment as them, and even when she received the university admission letter, she was ridiculed for taking shit luck.

It's just that many people don't see how Ma Ling buries his head in hard study every night after taking care of his frail and sick grandmother, these are only the old village chief who silently watches in his eyes, and it is also this old village chief who still has some prestige and ability to send Ma Ling to the university class of her dreams.

Just when Ma Ling was thinking about her future with a girl's mind, she didn't know that this was the last time she saw the sunset. What she had no idea was that more than two months of captivity and eventual death awaited her......
