Xu Jiuyan seems to care about the ratings of this show intentionally or unintentionally, but a few words are about to set off brainstorming outside the show. Zheng Wan'er asked: "Sister Jiu, what are the aspects to start from to solve the case?" ”

Xu Jiuyan said: "This question is actually very simple, as long as there is enough evidence. ”

"Does that still require detailed reasoning?" Yao Chunyu asked like a curious baby.

Xu Jiuyan nodded and said, "Reasonable reasoning is indeed important, but all reasoning must be based on the chain of evidence. If there are footprints, we can infer the height and weight of the suspect, as well as his walking habits, and even what he was carrying at the time of the murder. ”

Lu Yaochen looked at the wreckage of the big bag and asked, "What about this one without footprints?" ”

"We can do a mental portrait." Xu Jiuyan said.

Yao Qingyu said: "Is it the one from the FBI?" ”

Xu Jiuyan smiled slightly and said, "That's right, that's it." There are many types of psychological portraits, including the appearance portrait of the suspect, the portrait of the area of action, and many more. To put it simply, the modus operandi you have mastered, physical witnesses and witnesses can all be used as the basis for psychological portraits. ”

Lu Yaochen asked in disbelief, "Is this really fake?" Xu Jiuyan smiled and said, "If you don't believe us, let's try?" Xu Jiuyan borrowed a piece of paper and a pen from the program team, and said: "Give you a piece of paper and a pen, you write a person's name on the paper, he can be a man, of course, it can also be a woman, if you don't mind being riddled with scandals." Then tell me what kind of person he is in life, he can be strong, stubborn, kind, weak, and then I make a portrait, and you can see if it looks like it. ”

Lu Yaochen said confidently: "Okay, I don't believe you are so powerful, you can draw a portrait just by listening to your personality characteristics." ”

"Then give it a try." Xu Jiuyan said confidently.

Lu Yaochen put the note in his pocket and said, "Listen, this person is a person I am very grateful for, he has given me a lot of things, and it is because of him that I have become who I am today." He looks kind, but he is stubborn in his bones, and he is not only strict with his students, but also with himself, but if someone is in trouble, he must also be the first to help. ”

The pen in Xu Jiuyan's hand drew quickly, flying around on the paper like an elf, and after about ten minutes, a stick figure appeared.

Everyone looked at the painting in surprise and said in unison: "Is it Teacher Zhang Huiwen?" ”

"Is this person's name Zhang Huiwen?" Xu Jiuyan asked cutely.

Zheng Wan'er said in surprise: "You don't know Zhang Huiwen? Can you still draw him? ”

"Eh, I painted it based on what Lu Yaochen said, I have only heard his name of Zhang Huiwen, I don't know what he looks like." Xu Jiuyan said.

Yao Qingyu said: "Zhang Huiwen is a very famous songwriter in the music world, and he trains new musicians all year round, because he has been working behind the scenes, and it is normal for you not to know him. If I hadn't worked with him on the theme song of a TV series before, I might not have known him. ”

Lu Yaochen unfolded the note in his hand incredulously and said, "How did you do it?" How do you know I'm talking about Zhang Huiwen? ”

Xu Jiuyan smiled mysteriously and said, "This is much easier." Remember what I was talking about at the beginning? ”

Zheng Wan'er said: "What you said at the beginning was to write a person's name on a piece of paper, he can be a man, and if you don't mind being riddled with scandals, of course it can also be a woman." ”

"I have two messages in this sentence, one, you can draw any person, and two, this person is a man." Xu Jiuyan couldn't help but make everyone a little puzzled when she said it, Xu Jiuyan explained: "I'm talking about men first, and then I'm talking about women, and you will subconsciously give priority to men." And in the singer circle, you are notoriously scandal-free, so the person you write about must be a man. ”

Yao Qingyu asked suspiciously, "Then how do you know that this person looks like this?" ”

"Lu Yaochen told me personally." Everyone looked at Xu Jiuyan suspiciously, and Xu Jiuyan said: "The first thing Lu Yaochen said was that this person is very grateful to a person, he has given a lot of things, and it is precisely because of him that Lu Yaochen has become what he is today." From the analysis of this sentence, this person should be Lu Yaochen's elder. ”

"Can't it be a friend? You can also say that friends give a lot of support. Lu Yaochen asked impatiently.

Xu Jiuyan shook her head and said, "No, if it were your friend, you should say thank you for his companionship and support along the way." And if a person says that he has achieved who he is today, it means that this person is a teacher-level figure for him. ”

"You're really right, Zhang Huiwen is the producer of Lu Yaochen's first album, and Zhang Huiwen dug him out of the Conservatory." Yao Qingyu said.

Xu Jiuyan continued: "Later, you said that he looked kind, but he was very stubborn in his bones, and he was not only strict with his students, but also with himself. Such a person has a strong personality and looks like a static water, but his heart is surging, so he should be a slightly square face shape, a person who usually looks like an inconspicuous expression, his eyes should be very soft, and the bridge of his nose is not high or collapsed. Later, you said that if someone is in trouble, he must be the first to help. It means that he is a warm-hearted person, then he must be a round-faced person. ”

The children listened to the clouds and fog, and there was a feeling of watching a trick. Zheng Waner said: "If I hadn't seen it with my own eyes, and there was no script, I would have thought it was fake!" ”

Xu Jiuyan smiled slightly and said, "This, it's because it looks so amazing that the murderer can be caught repeatedly." ”

"It was a lot of fun!" Guan Zheng came from behind and said, "How is it?" ”

Xu Jiuyan spread her hands and said, "That's it, there are no footprints nearby, and there are no suspicious things." ”

Guan Zheng beckoned to the director and said, "Are the police coming?" ”

"No, it's a landslide, and I can't get in for a while." The director is also very anxious.

Chu Xiong asked suspiciously, "Why did it collapse without rain?" ”

The director said: "You say it's a coincidence, it happened to catch up with the coal mine next to it, and the amount of an explosive was not well controlled, and half of the mountain was blown up." ”

Guan Zheng looked at Xu Jiuyan and said, "Then we can't count on them, please help me find a cleaner place, and I will do the corpse restoration immediately." ”

The director nodded and said, "Okay, I'll go and talk to the village chief right away." ”

"Don't talk about the dead."

"Okay, got it."
