Humen Street, Sparrow Hutong Entrance, Bian Que Hall.

Such traditional Chinese medicine shops are not uncommon in the city of Beiping.

The old façade, the simple signboard, the lintel is nailed with a plaque, on which the three big characters of "Bian Que Tang" are written. The word is thin gold body, thin and straight, and the style is self-contained.

There is a table by the window in the store, which is specially used by the doctor to check the pulse.

The long counter is used to grab the medicine.

The Chinese medicine cabinet against the wall contains a dazzling array of medicinal herbs, and the lingering smell of herbs fills the air.

"Your illness is no longer serious, as long as you recuperate in peace, in this way, I will prescribe you two more pairs of medicines, and you will still decoction when you go back." At the table sat a man in a long shirt with a clear face and glasses, and he said to the old man in front of him with a gentle smile.

"Thank you, Dr. Wang." The old man said gratefully.

"You're welcome, you should!"

Wang Weishan turned his head and shouted at the counter: "Beans, take the medicine according to the prescription." ”

"Yes, Master!" Liu Dou, who has been following Wang Weishan's apprenticeship for two years, replied loudly.

At the same time, Chu Mufeng and Wang Gezhi walked in.

"Are the two officials going to see a doctor or taking medicine?"

Liu Doudi, who was quite clever, walked out from behind the counter and asked with a smile on his face.

"You're Wang Weishan, right?" Sweeping the audience, Chu Mufeng's eyes locked on Wang Weishan, who was sitting at the table to see a doctor, and asked directly.

"Yes, I am."

Wang Weishan stood up and said with a smile: "I don't know what the two officials have to do?" ”

"Wang Weishan, this is our ID, we are all from the Criminal Investigation Department of the Peking Police Department. I came here today because I want to ask you something, and you have to answer truthfully. Chu Mufeng looked at the other party and said in a deep voice.

Criminal Investigation Department of the Peking Police Department?

"Of course, of course, it is the duty of our people to cooperate with the police in handling the case, but I don't know what the two police officers want to ask?" Wang Weishan's eyelids trembled slightly, his pupils shrank, and he hurriedly responded.

Wang Gezhi, who was called by the way, didn't say a word, and completely looked like Chu Mufeng.

"You know Jian Ruyun, right?" Keenly caught Wang Weishan's expression, Chu Mufeng went straight in.

"Who? Jane what cloud? ”

Wang Weishan seemed a little dazed, frowned and thought about it, spread his hands and said, "Official, I don't seem to know this person." ”

"Don't know? How is it possible, he's your patient? Wang Gezhi, who was in charge of understanding the prescription, immediately said.

"Official, look at what you said, you also saw that I have a lot of patients who come and go here every day, and I may not all know their names?"

"The Jian Ruyun you are talking about may have seen me for a doctor, but I really don't have an impression, maybe I can recognize it when I meet him. Otherwise, I will bother the two officials to bring him over for me to see. ”

In the face of Wang Gezhi's question, Wang Weishan smiled slightly, and said these words without knots on his tongue.

"You ......" Wang Gezhi was suddenly a little speechless.

"Brother Wang."

After Chu Mufeng raised his hand to signal, he said tepidly: "Doctor Wang, you are right. With so many patients coming to see a doctor every day, it's normal for you not to know or forget Jian Ruyun. By the way, do you like cats? ”

"Cats?"

Wang Weishan raised his eyebrows slightly, and said with some hesitation: "I don't like it, this thing is too annoying!" Official, I don't like cats...... It shouldn't be illegal, right? ”

"Don't commit it, don't commit it!"

Waving his hand, Chu Mufeng asked a few more random questions, and suddenly asked coldly, "Wang Weishan, where did you hide your wailing?" ”

"Zang...... Ahem! ”

Wang Weishan almost subconsciously responded, but as soon as the word "hidden" was spoken, he was stuck on the spot, and then a look of panic flashed in his eyes, he coughed vigorously twice, lowered his head and wiped his glasses.

"Wailing? What is Wailing? Officer, don't play such a joke on me, I don't even know what a wailing is, how can I hide it? ”

"Are you sure you don't know?" Chu Mufeng's eyes were playful.

"OK, OK, OK." Wang Weishan shook his head like a rattle and said.

"Master."

At this moment, Liu Dou mustered up the courage to come over and said cautiously: "The medicine fried in it is almost ready, can you see if you can go and take a look?" ”

"Oh!"

Glancing at the apprentice, Wang Weishan begged: "Two officials, that pair of Chinese medicine is very important, can you let me take a look, and then accompany the two of you to continue chatting when you come out later?" ”

"Go ahead!" Chu Mufeng said indifferently.

"Thank you, sir!"

Raising his hand, Wang Weishan turned around and lifted the curtain and walked into the back hall, and Liu Dou also followed.

At this time, the original patients saw that the police were there, and they all walked away in a funny way, and the shop was empty and quiet.

"Brother Chu, is this doctor suspicious?" Wang Gezhi asked in a low voice after glancing at the door curtain.

"Nine times out of ten, it's him!" Chu Mufeng nodded and said.

Wang Gezhi suddenly perked: "Really? Where did you see that? Why didn't I see it? ”

"Look in his eyes!" Chu Mufeng said confidently.

Although the questions just now were very casual, in fact, they were a combination of fiction and reality, and fiction and reality.

From beginning to end, he was observing Wang Weishan's eyes.

You must know that lies are a language woven to cover up a certain motive or psychology, but such a lie is the most fragile and vulnerable in Chu Mufeng's eyes.

In his previous life, he had received special training in metaphysical thinking, and he could see through the suspect's lies at a glance during interrogation and see through the suspect's tricks.

It's like just now.

"Eyes?" Wang Gezhi asked with some suspicion.

"That's right, it's the eyes! Human beings are visual creatures, and the human eye is a true reflection of their inner state. Through the change of eyes, you can spy on the changes in the other person's heart. ”

"For example, the frequency of blinking is slow and then fast, which is a signal to lie. I don't know if you noticed it, when did Wang Weishan's blinking frequency become faster just now? ”

"This?" Wang Gezhi touched his head and smiled, he really didn't notice.

"He gets quicker when I ask the three questions of Jane Ruyun, the cat, and wailing. What does this mean? Shows that he is lying. ”

"Because when he lies, he will feel uncontrollably anxious and worried, and he can't help but blink rapidly, which is what we often call talking nonsense with his eyes open."

Chu Mufeng, who glanced at the door curtain and paid attention to the movement inside, continued: "Except for blinking, Wang Weishan didn't dare to look at me with both eyes when he was talking to me, and he was always subconsciously avoiding and dodging. ”

Also, when he lies, his eyebrows are raised and his eyes are wide open, especially when I ask a wail, what does it mean? It shows that he was surprised and frightened, and he didn't expect me to know about wailing. ”

"Brother Chu, what's the wailing?" Wang Gezhi felt that his IQ was a little insufficient.

"Wailing is the real cause of Jian Ruyun's death!"

Wang Gezhi looked confused, as if he was listening to a book from heaven.

"Come on, I'll explain it to you later."

After Chu Mufeng saw Wang Gezhi's appearance, the corners of his mouth curled, these are the basis of modern case-solving theories, but they are too advanced in this era.

Bang Dang!

Just then, there was a noise inside.

"Quick, Wang Weishan wants to escape!"

Chu Mufeng's face changed slightly, and the two rushed to the back hall without hesitation.
