Guan Zheng hung up the phone, and Xu Jiuyan asked, "Is the case closed?" ”

"Come on, let's go, go back to the team!"

"What are you doing when you go back? Watching the excitement? ”

Guan Zheng got out of bed, stepped on his shoes, put on his coat, and said, "Be steady." Pen Fun Pavilion www.biquge.info"

Xu Jiuyan sighed, helped Guan Zheng put on his coat, then bent down, put Guan Zheng's shoes on, and returned to the bureau together.

Guan Zheng stood at the other end of the double-sided glass, watching Li Chongyang and Xu Jiuyan interrogate Cong Kai.

Li Chongyang took Jin Yao's photo to Cong Kai and asked, "What is the relationship between this girl and you?" ”

"It's okay!"

"Doesn't matter? It doesn't matter if you buy her a lot of luxuries? Drained all your savings for so many years working in Nanyi? ”

Cong Kai's eyes were instantly filled with anger, and he said, "It's all this bad woman, she lied to me!" She was the one who left me with nothing! She deserves it! What I can't get, no one else can think of! ”

"How did you kill Jin Yao and Jiang Yingying?"

Cong Kai smiled and said, "They are so dirty, I had to put them in sulfuric acid and corrode their sinful faces, little by little!" ”

"Calm down, I'm asking you how you killed them."

"How did you kill it? I used a knife to cut their necks, put the blood into the plastic bucket little by little, and the test liquid turned red little by little, so beautiful and beautiful......"

Li Chongyang interrupted Cong Kai's exclamation and asked, "Why did you press Zhu Qian into Wang Shui alive?" ”

"Because she is too dirty, dirtier than Jin Yao and Jiang Yingying."

"Why?"

"Because Zhu Qian has a child, she still uses this child to extort money, but she has already beaten the child, you say, is she too dirty?"

Guan Zheng listened to the sinful voice, his fists clenched little by little.

Xu Jiuyan came out of the interrogation room, and Guan Zheng asked, "How is it?" ”

"Not good."

Guan Zheng smiled and said, "This case has your credit, let's go, please go to dinner." ”

Xu Jiuyan looked at Guan Zheng's bandaged hand with disgust, and said, "You can pull it down, just your hand, and still eat?" ”

Guan Zheng didn't speak, and pulled Xu Jiuyan to the hot pot restaurant opposite.

Xu Jiuyan sat down and said, "Do you love hot pot very much?" ”

"No, it's just that this family's food can be eaten near our Public Security Bureau."

It didn't take long for the dishes to be served. Guan Zheng reached out and picked up the plate and poured all the meat into the pot. Xu Jiuyan saw Guan Zheng pinching the spoon with difficulty, and said, "Do you need me to feed you?" ”

Guan Zheng said: "No. I saw Guan Zheng stretch out his left hand, pick up chopsticks, and eat quickly.

Xu Jiuyan asked, "Are you left-handed?" ”

"Why do you ask? Such an idiot's question. ”

Xu Jiuyan said: "Can you still use chopsticks with your left hand?" ”

"Why not? I can do what my right hand can do, and I can do it with my left hand. ”

Xu Jiuyan nodded and muttered, "Who knew you could have such great ability!" ”

Guan Zheng smiled and said: "I said that you are an idiot not because you don't know that my left hand can be used, but because you have been with me for so long, you don't even know my dominant hand." ”

"Should I know?"

Guan Zheng said: "Of course it should be, in China, the number of left-handers is relatively small, and if we know that the murderer is left-handed, then it will be much easier."

Left-handedness in the strict sense of the word is rare. First of all, the movements of the hand include pulling, throwing, twisting, holding, holding the pen, using the needle and many other actions. There are quite a few people who have different hands for different movements. If a person is accustomed to one side of the hand, the dominant hand of the two-handed movement may be the other hand.

Another factor influencing the judgment of left-handers is acquired correction. However, no matter how they are corrected, these people are still left-handed. If you consider the movement of the legs and feet, the problem is even more complicated. High jump, long jump, kicking, stepping, rubbing and other actions, many right-handers who use their hands 100%, but the movements of their legs and feet are dominated by the left side.

There are also some left-handers who are assimilated by the acquired right-handed environment and use the right hand. There are also left-handers who are corrected or assimilated, or who are born with similar left-handed advantages, and will become dexterous two-handers.

For the sake of a standard, it can generally be thought of as left-handedness as a person who is naturally left-handed in writing or using chopsticks, and a person who is naturally left-handed in sports. ”

Xu Jiuyan rubbed her head and said, "Talk about people!" ”

Guan Zheng put down his chopsticks and said, "You stand up and put your hands in your pockets." ”

Xu Jiuyan stood up and put her hands in her pockets, Guan Zheng handed the chopsticks to Xu Jiuyan, Xu Jiuyan reached out to pick them up, Guan Zheng held Xu Jiuyan's hand and said, "Do you see it?" ”

"See what?"

"When both of your hands are tied, you instinctively stretch out your right hand in the face of the situation. This means that your dominant hand is right-handed. ”

Xu Jiuyan sat down and said, "So what? You still haven't figured out which hand you think your dominant hand is. ”

"Didn't I say that? I said it! ”

Xu Jiuyan was shocked and said, "When did it happen?" ”

Guan Zheng smiled and said, "Tease you." If you want to know which hand is the dominant hand, you have to look at the emergency response. For example, a cup drops, or you can see which hand is wearing the watch and which hand is picking up something. Generally speaking, if a cup flies over, which hand is the dominant hand, and which hand wears the watch is the dominant hand. ”

Xu Jiuyan nodded and asked, "Then which hand is your dominant hand?" ”

"I'm double-handed."

"Huh? You can use both hands? ”

"Yes, writing, eating, etc., you can use your left and right hands."

Xu Jiuyan looked at Guan Zheng and said, "How many other things do you have that I don't know?" ”

"You don't know much!"

"How do I know if you don't say so?"

Guan Zheng said: "The criminal police are looking for answers in not knowing, if the murderer tells you, what else do you want the criminal police to do?" ”

Xu Jiuyan was a little deflated, pouted, and said, "If you don't say it, you won't say it." ”

Guan Zheng smiled: "Let's make a bet, if you win, I will hand over all my skills to you, if I win, you will honestly go to me to handle the case!" ”

"If I don't go, I won't be happy!"

"You're afraid of losing, aren't you?"

"Who's afraid to lose? It's better than that!"

"Walking then?"

The two of them got out of the restaurant, Guan Zheng didn't get in the car, took a turn outside, and went to the supermarket on the side to buy a bag of tea.

Xu Jiuyan followed behind and didn't speak. Guan Zheng paid the money and pulled Xu Jiuyan into the car.

Guan Zheng asked: "How many people were in the supermarket just now?" ”

“…… Four or five, right? ”

"It's eight, you don't count us and the cashier. Again, how much did I spend on my purchase? How much does each item cost? ”

"Well, I see this, 42!"
