“mmpi？” Li Yi took the phone and flipped a few pages down, confirming that it was a number of personality tests in Minnesota, "A blank test paper, why are you showing me this?" ”

"Have you read all the news today?"

Li Yi: "Do you mean a media person with a dream, the two things that broke out on this account?" ”

Feng Yuan nodded, "This test paper was found on Hao Xiaoxiao's computer, and it was sent to her by a netizen named 'Cleaner'. ”

After that, he also said a word. Feng Yuan looked at Li Yi and said word by word: "The game is over here, looking forward to the next time, just these two messages, there is no other chat history, I guess it was deleted remotely by that person." ”

Li Yi looked at the things on his phone, frowned, and said, "Minnesota has multiple personality tests, do you want to know what the murderer's purpose was in leaving this clue?" ”

"That's right."

Since the murderer has the ability to delete all other content, he must have his purpose in leaving these two items.

Li Yi touched his nose and said: "MMPI is so far, a very widely used and authoritative personality test, assuming that the murderer wants to measure Hao Xiaoxiao's personality, and she fills in this scale, there will inevitably be a personality test report about Hao Xiaoxiao, but now we only have a blank test paper in our hands."

"But what is his purpose in doing this, to determine Hao Xiaoxiao's mental abnormality?"

Li Yi said: "As far as I know, Hao Xiaoxiao has severe depression, which can actually be determined from her behavior yesterday, I don't know if Hao Xiaoxiao has seen a psychiatrist elsewhere, but if there is, you can go to find her case, I will take a look at it then, maybe I can help you." ”

Feng Yuan took his mobile phone and sent a message, saying, "I'll let people find it." ”

Shi Lean listened to it on the side, and suddenly asked with some curiosity: "Little brother, I have a question I want to ask you." ”

Little brother? Captain Feng was a little angry, why had he never called me so gently?

Li Yi couldn't hear Feng Yuan's inner shout, and said, "You say." ”

"Can a person change dramatically in two years? For example, from a quiet and well-behaved child to a cruel pervert with sadistic tendencies? ”

"Well, it's not common, but that doesn't mean it's impossible."

"Can you tell me?" Shi Tian put on a posture of listening to Xueba's lecture, obviously trying to study this problem thoroughly.

Feng Yuan knew that he was asking about Lu Xi, and it just so happened that he also wanted to hear Li Yi's opinion on the 'man in black'.

"Mr. Freud, the founder of the psychoanalytic school, believes that human psychology can be divided into conscious and unconscious, consciousness is the part of the mind that we can recognize, we know it and can control it, the unconscious is also called the subconscious, which means that we usually do not know that it exists, but it deeply affects people's lives, which usually refers to the **, secrets, thoughts and fears that are not tolerated by social norms and are deeply suppressed in the bottom of the heart."

"Freud believed that the unconscious has agency, that it actively exerts pressure and influence on human character and behavior, and that things that seem trivial to him are determined by underlying causes in the brain, but in a disguised form."

"The composition of human consciousness is like an iceberg, only a small part of the consciousness is exposed to the water, but most of the hidden underwater has a subconscious impact on the rest of the part, if you are talking about this person, who has experienced trauma in childhood, or his blood is born with a cruel factor, then in the first half of his life, because of the various behavioral rules of human society, it will be well suppressed, but his personality has great potential risk factors, once it is placed in an environment that is easy to induce, It's easy to bring out what is hidden in his heart. ”

Li Yi said a lot of psychological terms, Feng Yuan was very confused and had a headache when he heard it, but he also heard a little, "You are saying that it is because of a certain person or a certain environment that stimulates the subconscious meaning in his heart, so he has undergone such a big change?" ”

Li Yi nodded, "Theoretically speaking, that's the case, what Miss Shi just said was that from a well-behaved and lovely child to a big pervert, if ordinary people have been happy and healthy and have a happy life, it is impossible for such a big change to happen." ”

Feng Yuan remembered what Shi Tian said, Lu Xi disappeared two years ago, so if the man in black in the video was really him, he didn't dare to imagine what he had suffered.

"Miss Shi." Li Yi turned his head and asked, "Let me guess, is the person you are talking about the man in black who has been hanging on the hot search on Weibo today?" ”

Shi Tian raised his eyebrows in some surprise, "How do you say that?" ”

Li Yi smiled and said: "This is my guess, since you asked me this question, then I guess that there really is this person, plus you came with Ah Yuan today, he came to consult me about things related to the case, and today's news was mentioned in the middle, generally speaking, Ah Yuan will not allow ordinary citizens to be present in the case, so I guess that this person is related to the case, and if you meet the conditions, then only him." ”

'Pa~Pa~' Shi Tian stretched out his hands and applauded: "I really deserve to be a psychology expert, and my skills in peeping into people's hearts are almost full, Dr. Li, is it possible that I am thinking about something now, you can see it?" ”

Feng Yuan slapped Shi Tian and said, "What do you want?" He studied psychology, not a god, and he can know what you think at a glance! ”

"Oops! Xiaoyuan, what are you doing beating me? Murder your mother! ”

What the heck? Feng Yuan really wanted to slap Shi Tian's head again, but fortunately, Li Yi stopped him in time.

"Huh." Li Yi said with a smile: "Ah Yuan is right, psychology is a science, in fact, it is not so magical, you can see people's thoughts at a glance, this is a set of scientific theories accumulated by countless ancestors after a hundred years, we just happened to be born in a prosperous era." ”

"Little brother, you are good, handsome, and knowledgeable, and you don't know which girl will be cheaper in the future?" Shi Tian said regretfully: "If I hadn't had our family Xiaoyuan, I would really want to fall in love with you." ”

"What did you say?" Feng Yuan exploded all of a sudden, "What's your family, when did we become so acquainted?" Don't frame me. ”

"Xiaoyi, don't listen to her nonsense, she is still a yellow flower guy."

Li Yi: Why do I suddenly feel a little cold?
