Li Dan took a general look at this "Criminal Psychology" and found that it was not an obscure psychological work.

Instead, it mainly includes all kinds of real crime cases, and analyzes the psychological conditions and mental processes of the criminals in each case from a deep level.

In Li Dan's brain, every crime case has become a logical reasoning test question.

It is possible to speculate on the next move of the criminal based on logical thinking while watching, and at the same time, it is also possible to find out what loopholes and flaws exist in each move to facilitate detection.

At this moment, Li Dan has already fantasized about himself as a detective who fights crime.

Through a series of clues in the case, logical reasoning is carried out to bring the real criminals to the surface, and a variety of arrest scenarios are envisaged to bring the criminals to justice.

However, the criminal cases in this "Criminal Psychology" book are too ordinary, and Li Dan lost interest after reading it casually for a while.

Especially in the pages, there were still some colorful small denominations of cash scattered in the pages, and Li Dan didn't dare to look through them for a long time.

If my mother came back early and saw this scene, my father's life might not be guaranteed......

"Are there any books like this, but the methods of crime are more subtle, and the criminals are more sophisticated in counter-reconnaissance?"

Li Dan searched for a long time in the bookcase, and then used his mobile phone to search for a long time in the online mall.

It turned out to be a little disappointing for him.

The most classic detective novel is naturally the "Sherlock Holmes Detective Collection" series.

However, the cases and characters in the novel are all antiques from two centuries ago, and there is little reference significance compared to the modern society with highly developed technology.

Detective novels written by contemporary writers, such as "The Code of the Riverside Scene at Qingming Festival", "White Night Walking", and "High IQ Crime" series, tend to focus more on the story, and the cases are particularly distorted.

"I just want to see real cases, not novels......"

Li Dan couldn't arouse any interest in reading these novels, so he simply went to the living room and turned on the TV, and then used the smart TV box to play the cartoon of "Detective Conan".

Skipping the plot that has nothing to do with the case, Li Dan sits on the sofa and starts a case-solving duel with the RB high school student detective Kudo Shinichi in the anime.

When enough clues were collected in his brain, Li Dan directly jumped the plot to the end to verify whether his reasoning was correct and what were the differences in details with Kudo Shinichi's reasoning.

In less than half an hour, Li Dan has watched more than a dozen episodes of the anime, not only the presumed criminals are exactly the same as the anime, but even the reasoning of the case is similar to Kudo Shinichi.

Of course, Li Dan disdains the flashy and bizarre criminal methods in the anime.

Although this is the biggest attraction of the "Detective Conan" comics, in reality, there is no criminal who uses such a complicated way to commit crimes!

In this sense, the case shown in "Detective Conan" does not quite meet Li Dan's expectations.

At this time, the sound of the key unlocking came from the security door.

Then the door opened from the outside.

Li Dan originally thought that his mother was back, but after taking a look, he found that it was his father who had not seen him for several days.

Li Changsheng hadn't closed his eyes for two days and two nights.

If it weren't for the leader ordering him to go home and rest for the night, and change his mind by the way, he would have fought all night tonight.

"Balls? How did you get back? ”

Li Changsheng saw Li Dan sitting on the sofa at first sight, and he didn't slow down for a long time.

Seeing his son on nights other than weekends made Li Changsheng somewhat uncomfortable.

Li Dan looked at his father's obvious weight loss, his eye sockets were deep, and his face was scruffy, as if he had aged several years all of a sudden, and his heart couldn't help but feel sour: "How many days have you been working overtime?" How did you get to be like this? ”

Li Changsheng smiled faintly, he also knew that his current appearance must be terrifying.

"Where's your mother?"

Li Changsheng looked at the kitchen vigilantly.

At this time, Lin Ya should be cleaning in the kitchen.

"She went out for a walk."

"Great! Dandan, you go and cook me a bowl of instant noodles and lie down with two poached eggs! ”

Li Changsheng breathed a sigh of relief, hummed a song and turned around and walked into the bathroom.

"Dad, my mom cooked a lot of dishes tonight, and there's a lot left! Would you like to warm it up? ”

Li Dan asked at the top of his voice.

"You dare?! I just eat instant noodles and nothing else! ”

Li Changsheng yelled loudly in the bathroom, as if he was afraid that the other party would not hear it.

"What are the nutrients of instant noodles? I don't understand! Why do you father and son like to eat this junk food?! ”

At this time, Lin Ya suddenly appeared at the door, looked at Li Dan and said, "Go!" Heat up that leftovers and let your dad eat them! ”

"Okay!"

Li Dan smiled, and immediately jumped up from the sofa.

"Wait! Don't get hot with that yellow croaker, it's specially made for you! ”

Li Dan's elated mood suddenly cooled down for most of the time.

After the meal was heated, Li Changsheng also came out of the bathroom.

After taking a hot shower and shaving his beard, Li Changsheng returned to his usual radiant appearance, but he looked a lot thinner.

Glancing at Li Dan fiercely with his eyes, Li Changsheng walked to the dining table helplessly, raised his chopsticks and hesitated in the face of the leftovers on the table.

The reheated dark dishes are even more worthy of their name, and they are intimidating from the outside.

"Mom, I'll add another dish to my dad. He's been working overtime for days, and it's not easy to ......"

Li Dan asked tentatively.

Li Changsheng's body shook slightly, this kind of request is tantamount to challenging Lin Ya's authority as a family chef, it is very dangerous, if you don't get it right, a war will break out directly!

Lin Ya opened her mouth, hesitated for a moment, and sat down on the sofa with an "um" sound.

"How old are you and still watching cartoons...... Do you still want to watch it? If I don't watch it, I'll change the channel. ”

Lin Ya's move stunned both Li Dan and Li Changsheng.

What's wrong with this queen in the family today?

Not only did she acquiesce to her son's challenge to her chef's authority, but she didn't get angry at all at all at at her son watching cartoons!

I even have to ask my son's opinion before changing the channel?!

Li Changsheng sat on the dining table, slowly put the chopsticks on the bowl, turned to look at Lin Ya sitting on the sofa, and showed a thoughtful expression.

"It seems that my family status is going to drop one place again? From now on, it's the end of the year? However, who is higher and lower in the status of these two girls......"

Li Changsheng was still pondering, and a dish of fried shredded pork with garlic sprouts was served, and a large bowl of steaming tomato and egg drop soup was served.

The soup is sprinkled with green shallots and dripping with sesame oil, and the red, yellow and green color combination looks very attractive.

"That's what dinner should look like......

Li Changsheng was so moved that tears were about to fall.

"Lao Li, don't get carried away! You have to finish my cooking! Not at all! ”

Lin Ya was looking at the TV, and suddenly a sentence popped up.

Li Changsheng instantly felt a lot of pressure......

Li Dan hurriedly cleaned the spatula and went back to the house.

Because, he just received a text message on his phone.

A transfer SMS.
