"Good!" Wang Daoke agreed without thinking, and he began to shake his head excitedly, he expected that Li Bi's answer could not be consistent with his own. Pen "Fun" Pavilion www.biquge.info

"A word is decided, but the premise is that you must identify the real murderer yourself." Li Bi reminded.

"No problem!" Wang Daoke waved his hand, he crossed his hands, twisted back and forth, he couldn't wait to start the game now.

"Good!" The corners of Li Bi's mouth on the right side rose slightly, he took out the pen he had prepared from his pocket and handed it to Wang Daoke, then tore off a page from the draft book on the desktop and handed it to him, "You can write on this paper!" ”

"Good!" Wang Daoke took the paper and generously agreed.

Next, they all quietly began to write.

Five minutes later, Wang Daoke couldn't hold it anymore, he bit the tip of his pen and said, "Hey, on the other side, you don't know that I'm illiterate, I can't read a few words, how can I write?" ”

Li Bi raised his head, his eyes rolled, and he made a suggestion: "Otherwise!" Just write simple numbers, and we write his gender, age, and height respectively. These are Arabic numerals except for gender, and if you think it is male, you can write "1", and if you think it is female, you can write "2", which is all right, right? ”

Wang Daoke thought for a few seconds, agreed to Li Bi's suggestion, and began to bow his head and write seriously. The interrogation room was so quiet that even the sound of flies could be heard.

"Are you done?" Li Bi raised his head and asked in a low voice.

"Yes!" Wang Daoke carefully folded the note and held it in his hand.

"That's good!" Li Bi's eyes swept over his movements, and he tore off the paper on which he had written the contents of the draft book, "How about we exchange them now?" After the exchange, you will know what the other party wrote! ”

"Good!" Wang Daoke piggybacked on a childish face with a smug smile, as long as the content written is different, he wins, and his chances of winning are too high.

"Remember to bet and lose!" Li Bi handed him the karma paper in his hand and emphasized it deliberately.

"That's for sure, you adults are so grinding and chirping! Can you ......" Wang Daoke snatched the note he had brought over, but began to be stunned when he saw what Li Bi wrote.

"How is that possible?" Wang Daoke blushed before squeezing out a few words, and he stammered: "How do you know the murderer, you ...... At that time...... In there? ”

"Would you like to lose the bet?" Seeing that Wang Daoke's jaw was about to fall to the ground in surprise, Li Bi emphasized again.

"You...... How do you know? His face was blue and white, and he saw that the note he had written was already in Li Bi's hand, and he felt that something was wrong, and he was about to reach out and grab it.

“1、25～30、170～175。” Li Bi narrowly avoided Wang Daoke's competition, opened the note and began to read.

"You mean the killer was male, between 25 and 30 years old, and between 170 and 175, right?" Li Bi glanced at the note and wrote it down.

"You ......" Wang Daoke stood up, he still couldn't believe it, looked at the note, and then looked at Li Pen, the content on the paper was exactly the same as what he wrote.

"What? Do you have any questions? Li Bi put the note on the table and grinned.

"You ...... Don't you think I'm a murderer? Wang Daoke asked with a confused expression.

"Yes, I once doubted you, but it was quickly ruled out." Li Bi nodded, he smiled at Wang Daoke in a friendly manner, and decided to explain to him well, because he had already checked the information of this Wang Daoke, this person was clever since he was a child, and he never forgot everything, but he didn't use it on the right path, and he didn't do his job all day long. "Do you want to know how I know you're not a murderer?"

Wang Daoke listened carefully and did not answer.

"First, the murderer is confirmed to be the person with the ring on the right index finger, you are not wearing anything on your hand, and there is no trace on the right index finger because of the ring." Seeing that he was paying attention to his hands, Li Bi continued with a smile: "And according to the fist marks left on the deceased's body, the person who has such strength to beat Ah Ming to death must be a tall and mighty man!" With your little body, no. ”

"......" Wang Daoke is fascinated by listening, he loves to listen to reasoning stories since he was a child.

"Now let's talk about it, how do I reason about the age and height of the murderer?" Li Bi grinned, his hands crossed and moved closer to the table.

"How to reason?" Wang Daoke asked impatiently.

"Okay, I can tell you, but before you do, you have to answer me a question." Li Bi said, poked his head over again, and asked in a low voice, "Have you ever seen the murderer?" ”

"I ......" Wang Daoke hesitated, he remembered what happened that night, about eleven o'clock in the evening, he had just come out of the Internet café, when he passed by the café, he saw that the lights of the café were all out, only the lights at the gate were on, and at this time the door was open, he was secretly happy in his heart, he thought that they had forgotten to lock the door, and he was thinking in his heart that he wanted to go in and steal something valuable, but he saw it when he went in......

"See his back!" He remembered what had happened that night, sweat broke out on his forehead, he sat up straight in some panic, and suddenly covered his face with his hands.

"It's okay, you think slowly, don't worry, now I'll tell you how I reasoned?" Seeing that he was reluctant to talk about what happened that day, Li Bi began to talk about light topics to divert his attention.

"First of all, the height is determined according to the fist marks left by the murderer, the fist marks are concentrated in front of the deceased's chest ribs, when ordinary people hit the opponent with their fists, they will fix the opponent's collar or shoulder with one hand, and the other hand is in a fist state, the arm hangs down, the forearm is bent at 90 degrees along the elbow joint, and the horizontal smash is on the beaten person's body, that is to say, the distance from the concentration point of the wound on the beaten person's body to the ground is consistent with the height of the point where the murderer's elbow is lowered. The height of the murderer can be determined based on the ratio of the height of the human body to this distance. As he spoke, Li Bi led Wang Daoke to the open space next to him, playing the murderer himself, he played the victim, and showed him a demonstration.

"I see, you're really good." Wang Daoke looked at him with adoring eyes, he felt that he was not the same as those policemen outside, he suddenly raised his head again and asked, "What about his age?" How do you calculate? ”

"This ......" Li Bi sat back on the stool and began to sell the guanzi, he said, "I can't tell you until I catch the murderer." ”

"Alright, now you should tell me what you saw at the café that night, and be willing to lose the bet." Li Bi reminded him again.

"Okay." He seemed reluctant to remember the events of that day, but he decided to speak.
