Xiumen Street, the entrance of Maque Hutong, Bian Que Hall.

Such Chinese medicine shops are not uncommon in Beijing.

An old facade, a simple sign, a plaque nailed to the lintel, and the three big characters "Bian Que Tang" are written on it. The characters are thin gold, thin, straight and upright, and have their own style.

There is a table next to the window in the store, which is specially designed for doctors to take their pulse and treat patients.

The long counter is used to grab medicine.

The traditional Chinese medicine cabinet close to the wall is filled with a wide variety of medicinal materials, and the air is filled with the lingering smell of herbs.

"Your illness is not serious. Just rest as long as you rest as possible. In this way, I will prescribe two more medicines for you and decoct them after you go back." A man with a long robe with a clear face and glasses sat next to the table. He said to the old man in front of him with a gentle smile.

"Thank you, Dr. Wang." The old man said with gratitude.

"You're welcome, it should be!"

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

"Yes, Master!" Liu Dou, who had been following Wang Weishan for two years, responded loudly.

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

"Are you going to see a doctor or get medicine?"

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

"You are Wang Weishan, are you?" Chu Mufeng asked directly by scanning the audience.

“Yes, I am.”

Wang Weishan stood up and smiled and said, "I wonder what the two officials are doing?"

"Wang Weishan, this is our certificate. We are all from the Criminal Investigation Department of the Peking Police Department. Today I came here to ask you something, and you must 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 our people's obligation to cooperate with the police to handle the case. I just don't know what the two police officers are asking?" Wang Weishan's eyelids trembled slightly, his pupils shrank slightly, and he quickly responded.

Wang Gezhi, who was called by the way, said nothing, and was completely in a manner that he was mainly Chu Mufeng.

"Do you know Jian Ruyun?" He keenly captured Wang Weishan's expression and Chu Mufeng went straight in with one blow.

"Who? Jane What Cloud?"

Wang Weishan seemed a little confused, frowned and thought for a while, spread his hands and said, "Official, I don't seem to know this person."

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

"Official, look at what you said, you have also seen it. There are many patients coming and going here every day, and I may not all know the names?"

"The Jian Ruyun you mentioned may have come to me for treatment, but I really don't remember it. Maybe I will recognize him after meeting him. Otherwise, please let the two officials bring him over to me and have a look."

Facing Wang Gezhi's question, Wang Weishan smiled slightly and said these words without knotting his tongue.

"You..." Wang Gezhi was speechless.

"Brother Wang."

After Chu Mufeng raised his hand and signaled, he said twitchlessly: "Doctor Wang, you are right. It is normal for you to not know or forget Jian Ruyun every day. By the way, do you like cats?"

"cat?"

Wang Weishan raised his eyebrows slightly and said hesitantly: "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, no offense!"

After waving his hand, Chu Mufeng asked a few more questions casually, suddenly asked: "Wang Weishan, where did you hide your wail?"

"Hide...hehe!"

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

"Whispering? What is wailing? Police officer, don't joke like this with me. I don't know what wailing is, so how can I hide it?"

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

"Confirm sure." Wang Weishan said as he shook his head like a rattle.

"Master."

At this moment, Liu Dou took the courage to come over and said carefully: "The medicine that was decocted inside is almost cured. Can you see if you can go and have a look?"

"oh!"

Looking at his apprentice, Wang Weishan asked, "Two officials, that pair of Chinese medicine is very important. Can I take a look and then continue chatting with you later?"

"Go!" Chu Mufeng said calmly.

"Thank you, sir!"

With his hand raised, Wang Weishan turned around and raised the curtain to walk into the back hall, and Liu Dou followed in.

At this time, several patients saw the police there, and they all left tactfully, and the shop was empty and quiet.

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

"It's probably him!" Chu Mufeng nodded and said.

Wang Gezhi was immediately excited: "Really? Where did you see it? Why didn't I see it?"

"It can be seen from his eyes!" Chu Mufeng said confidently.

Although the questions just now were very casual, they were actually a combination of virtual reality and real reality.

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

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

He had received special training in physical and spiritual thinking in his previous life. During interrogation, he could see through the suspect's lies at a glance and see through the suspect's tricks.

Just like just now.

"Eyes?" Wang Gezhi asked suspiciously.

"That's right, it's the eye! Humans are a visual animal, and human eyes are the true reflection of their inner state. Through the change of eyes, you can see the other person's inner changes."

"For example, the blinking frequency is slower first and then faster, which is a signal to lie. I wonder if you have noticed that when did Wang Weishan's blinking frequency become faster just now?"

"This?" Wang Gezhi touched his head and smiled embarrassedly. He really didn't notice it.

"He got faster when I asked Jian Ruyun, cat and wailing. What does this mean? It means he is lying."

"Because when lying, he will feel anxious and worried, and will blink quickly, which is what we often say when we open our eyes."

Chu Mufeng, who glanced at the curtain and noticed the movement inside, continued, "Apart from blinking, Wang Weishan dared not look at me in front of me when he was talking to me. He was always subconsciously avoiding and dodging. This kind of unrestrained look is guilt."

"Also, when he lies, his eyebrows will be raised and his eyes will be wide. Especially when I ask for a wail, what does it mean? It means his surprise and fear, but I didn't expect that I would actually know howl."

"Brother Chu, what's the wailing?" Wang Gezhi felt that his IQ was not enough.

"Waoing is the real reason for Jian Ruyun's death!"

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

"Come on, let's explain to you later."

After Chu Mufeng saw Wang Gezhi's appearance, his mouth curled up. These are the basis of modern case-solving theory, but it was too advanced in this era.

Bang!

Just then, a sound came from inside.

"Hurry, Wang Weishan is going to escape!"
