Controlled experiment

Chapter 4

Du Yusheng has always felt that the most invisible thing in this world is the human heart, and the most difficult thing to grasp is also the human heart.

From the mitral valve to the tricuspid valve, from the aortic valve to the pulmonary valve, you have no way to visually see their circulation in it.And the hospital is like a hood for the heart, you can easily see people's hearts when you walk into the hood.There are various states in the world, you can always see any state in the hospital.In front of life and in front of choices, the appearance you show is your original appearance. Anyone will lose their disguise in front of life.

Sitting in the waiting area, Du Yusheng looked at the registration form in his hand and the numbers on the electronic screen, and sighed deeply.

NO.20, No. 45.

"...I have to wait until the year of the monkey?"

Xiaobai looked at Du Yusheng with a little apology: "When I came, I could only hang up here."

Du Yusheng scolded: "You don't know how to buy from scalpers?"

"Then you can't add money?" Xiaobai thought for a while and added: "Shall we reimburse you?"

Report to your uncle.

"You are so frugal." Du Yusheng snorted coldly.

"...Brother Yu, if you don't manage your house, you don't know that daily necessities are expensive."

"That's true." Du Yusheng said indifferently: "If the old man is good, he can directly buy some seasoning factory."

Xiaobai actually wanted to say something, but Du Yusheng pretended invisible to force him to swallow the words.

Before coming, Du Yusheng thought about going in directly as a policeman, but after thinking about it, he went in as a policeman, which would not have a good influence on other doctors. Besides, there are so many patients waiting behind him, and it is not civic-minded to jump in the queue openly. , I asked Xiaobai to register, who knew that Xiaobai was honest, and really went to the outpatient clinic to register.

Thinking of this, Du Yusheng sighed again holding his registration form.

While waiting, Xiaobai answered the phone.

Another team found fibers of clothing belonging to Mrs. Luo in the house outside the housekeeper

Du Yusheng nodded and said: "Tell them, check whether he has cold medicine with the same ingredients as Luo Daheng's before he died, and get the surveillance video of the pharmacy around the butler to see if he has bought related medicines recently. , Pay attention to whether Daheng Luo had any assets distribution during his lifetime, especially the one belonging to Mrs. Luo."

"You suspect the two of them?" Xiaobai said: "... I don't think they look like murderers, so just... have an affair."

Du Yusheng looked at Xiaobai angrily, "You just treat it as a routine examination, understand?"

After hanging up the phone, Du Yusheng started to play with his mobile phone. Xiaobai took a sneak peek and found that he had also changed the wallpaper of his mobile phone to the photo of the announcement.

The two sat staring at each other from 02:30 to 04:30, the last date of the day.

Li Yao's name was written in black and white on the sign at the door. Du Yusheng's eyes lingered on it for a moment.Du Yusheng asked Xiaobai to wait outside.

This was the first time Du Yusheng met Li Yao. Later, Du Yusheng would always think of this scene. He felt that he should have seen something from Li Yao long ago.

If he had seen it earlier, he would not have planted such a big somersault on him.

His office was clean and tidy, as every doctor should be.A red pennant hung on the wall of the consulting room, on which the eight yellow characters of "Living Hua Tuo" were reflected.

Du Yusheng stood in the empty consulting room for a few seconds, Li Yao came out wiping his hands, saw Du Yusheng, and smiled politely.

He was as good-looking as in the photo, seemed to be well-educated, with a doctor's unique clean breath, and sat down upright.He reached out and squeezed the hand sanitizer on the table, and politely rubbed his fingers under the table.His skin was very fair, and it seemed that the blood vessels under the skin could be seen with a little force. Du Yusheng looked at him from top to bottom.

"Hello, what's wrong?"

His voice is also nice, not lukewarm.

Du Yusheng came back to his senses and coughed lightly.

"I'm from the Huandao branch." He took out his ID card and waved it in front of Li Yao's eyes.

Li Yao pinned his work ID to his chest.ID photos can always show your ugliest appearance, but for Li Yao, it seems to be an accident. He even took good-looking photos of his work ID. Compared with him, he is a ruffian. Tuck his work permit into his pocket.

Hearing the words Huandao Branch, Li Yao's face changed slightly, but he still maintained a decent smile.

"...Is there something wrong?"

Du Yusheng nodded, "Do you know Daheng Luo?"

Li Yao smiled and said, "I am his personal doctor."

"So, you have been taking care of Daheng Luo's health?" Du Yusheng said, "I heard that he has been in poor health?"

Li Yao smiled apologetically, "This is his personal matter, it's not convenient for me..."

"He died." Du Yusheng added: "The night before yesterday."

Li Yao's decent smile froze for a few seconds, and soon he shook his head regretfully.

"Mr. Luo has heart disease, high blood pressure, and bronchial asthma. He is very busy at work, and his physical condition is largely caused by his work status." Li Yao added: "Sometimes the body and work are incompatible legal considerations."

What he said were all clichés with no practical meaning.

"So, Mr. Luo's death is related to his body?"

Du Yusheng didn't answer the question and asked, "Where were you the night before yesterday?"

There was a simple calendar on Li Yao's desk, on which he circled a few days with a red pen, so far away, Du Yusheng couldn't tell which days were drawn on it.

"I had an operation the night before, and I went home after the operation."

"What time did you get home?"

"Eight o'clock or nine o'clock? I can't remember the exact time."

"After returning home, has Dr. Li been to other places?"

Hearing this, Li Yao smiled.

He is also very good-looking when he smiles, the corners of his mouth are not raised too much, and there is a slight smile in his eyes. He has a sense of distance but makes you feel very comfortable.Du Yu was poor at words, so he could only think of the word "good-looking".

"Are you interrogating me?"

Du Yusheng laughed awkwardly, "No, I'll just ask."

Li Yao is a smart man who understands what Du Yu was born with.

"I didn't see Mr. Luo that night."

Oh, never seen it.

Who is the person in the surveillance video.

Du Yusheng really wanted to ask, but he swallowed the words.If you can hear lies in his words, there is something wrong with him.However, Du Yusheng didn't intend to expose him, nor did he want to continue asking.

Before leaving, he shook hands with Li Yao politely.

"Doctor Li, there is something I want to consult with you." Du Yusheng didn't let go of his hand, but still held it. "Do you know that eating too much nitroglycerin will kill you?"

Li Yao lowered his head and smiled.

"I'm a doctor, and I learn to save people."

Du Yusheng really wanted to see something from Li Yao's smile, but his smile was so natural that Du Yusheng couldn't see anything.

The only thing I can feel are those hands.

There are calluses on those hands, and Du Yusheng also has them, and they are also in the same position. Compared with the scalpel, Du Yusheng feels that Dr. Li is more like the calluses left by holding a gun all year round.
