Shu Min has seen a lot of smiles, sad, happy, evil, innocent, and the most memorable of them is the Mona Lisa's smile.

For 500 years, people have been indifferent to the mysterious smile of the Mona Lisa, which seems to be felt differently by different viewers or at different times, sometimes with a comfortable and gentle smile, sometimes with a serious smile, sometimes with a slight sadness, and sometimes even with ridicule and ridicule.

Shu Min went to the museum several times to see the Mona Lisa's smile, but she was never able to appreciate the essence, and since then, this smile has solidified in her impression as synonymous with mystery.

Now, looking at the shallow smile on the corner of Li Xianyun's mouth, she actually had that feeling again, the nervous figure who was crying with his legs before was gradually changing to mysteriousness.

"I'll take a closer look. ”

Shu Min didn't dare to ignore Li Xianyun's opinion, and carefully investigated in the room.

"There are four groups of footprints in the room, and according to the size and distribution of the footprints, these four groups of footprints are the deceased and the deceased's daughter, as well as you and me, and there is no fifth group of footprints. ”

"As for fingerprints, you have to wait for the physical evidence department to extract them, but the doors and windows are normal, and there is no trace of anyone breaking into the room at all. ”

"If there is a murderer, that murderer should be an acquaintance, has the key to this house, opened the door and came in, and he has a strong sense of anti-detection, probably wearing shoe covers and gloves. ”

Shu Min carefully checked inside and out, but still found nothing, and could only come to the conclusion that an acquaintance committed the crime and had a strong sense of anti-investigation.

"Acquaintances committing crimes?" Li Xianyun nodded with a smile, "You're right." ”

"The deceased just fell from the building, and the murderer hasn't run far yet!" Shu Min said and walked out the door, "I'll chase it immediately!"

"Wait a minute, where do you want to chase?"

Li Xianyun grabbed Shu Min's arm.

"I first went to the property to get surveillance, and anyone who went out of the community after the death of the deceased was suspicious. ”

"Do you know how many doors there are in the community, what if there are small doors that are not monitored?"

"Then, you go with me. ”

"What if the murderer didn't run away at all after killing someone?"

"It's impossible, isn't it?

"Sure enough, it's an intern, it's really inexperienced, such a perfect murder, why did the murderer run away, didn't he tell the police that he had a problem as soon as he ran?"

"So what do you say?"

"Don't worry, I'll ask you two questions. ”

"Hmm. ”

"In a secret room, there are two people, one is a thirty-year-old woman, the other is a thirty-year-old strong man, the woman died suddenly, and there is no trace of outsiders breaking into the secret room, excuse me, who will you suspect. ”

"Of course it's that thirty-year-old strong man!"

"The second question is that there are still two people, one of them is still a thirty-year-old woman, and the other is an eighteen-year-old young man, the woman also died suddenly, and there is no trace of outsiders breaking into the secret room, may I ask, who would you suspect?"

"Of course it's an eighteen-year-old young man, aren't these two questions the same, why did you ask them twice?"

"Do you know that these two questions are the same?" Li Xianyun spread his hands, "I thought that if you change the person who is with the woman, you won't understand." ”

"How come!" Shu Min snorted, "I'm just inexperienced, in the police academy, my grades in all subjects are the first!"

"Won't it?" Li Xianyun hooked the corners of his mouth and smiled again, "Aren't we staying in such a secret room now, the woman is dead, and there is no trace of outsiders breaking into the secret room, but who are you suspecting now?"

"You mean ······" Shu Min suddenly understood what Li Xianyun meant, her small mouth opened into an "O", her eyes looked at Li Xianyun directly, and she was stunned by Li Xianyun's brain, "Are you kidding, are you telling me that it was the nine-year-old daughter who killed the murderer!"

"Nine-year-old?" are you sure?"

"Nine-and-a-half-year-old, ten-year-old, even if she's a little older, it's impossible to kill someone, she's afraid she hasn't even stepped on an ant to death!"

"Give me your phone. ”

"Huh?"

"Cell phone!"

"Oh. ”

Shu Min took out the mobile phone from his bag and handed it to Li Xianyun.

Li Xianyun took the mobile phone and pressed the home button, Shu Min then remembered that he was going to unlock Li Xianyun, his mouth moved, and before he could make a sound, the mobile phone actually displayed the main interface!

"How is that possible?"

Shu Min's red mouth opened wide again, this seems to be her biological mobile phone, why can others unlock it casually?

"You look at him, how old do you think he is. ”

Li Xianyun searched for a photo and put it in front of Shu Min's eyes.

"How did you turn on my phone?"

"You don't understand it. Li Xianyun shook his phone, "Don't care about these inconsequential little details, how old are you?"

"Twenty?"

Looking at the handsome and damp face on the phone screen, Shu Min guessed.

"This is Baidu Encyclopedia's information, you can see it yourself. ”

Li Xianyun threw the phone to Shu Min.

"He's thirty-nine years old!" Shu Min exclaimed, "Oh my God, how is this maintained?" Wait, he also endorsed L'Oreal, is this skin care product really that easy to use? Do you want to try it? But, it's so expensive······"

"Hey!"

"Ahem, I mean, he's so young, he looks half his real age. ”

"You're telling me now, the one in the bedroom, she's really only nine years old?"

"It's different, that star, he looks young because he is well maintained, his living conditions are good, etc., but no matter how good a person is, he won't make himself look only nine years old, right?"

"There's a word called 'dwarf', you've probably heard it, right?"

"The dwarf is just small in stature, but also an adult, that child, like an adult's face?"

"You're mistaken, I'm not saying she's a dwarf, but I'm expanding your mind, since someone can look like a child because of illness, then why can't someone look like a child because of illness or other reasons?"

"How can there be such a disease!"

"Do you know how many diseases there are in the world?"

"I don't know. ”

"Then how dare you assert that there is no such disease?"

"No, it can't be, it's ridiculous. ”

After some questions and answers, Shu Min felt that he was about to be driven crazy by Li Xianyun.

The mother fell from the stairs and was murdered by the nine-year-old child of the family, God, this is not a novel, how can there be such a?
