Controlled experiment

Chapter 9

Du Yusheng looked at Li Yao's face and smiled.

The two were very close. Du Yusheng thought that Li Yao was about the same height as him, but now he seems to be a little taller than him.Li Yao's body proportions are perfect, his face is good, his clothes are clean, his hair is not greasy at all, even his shoes are spotless, and his whole body is full of this kind of smell that Du Yusheng likes.

Du Yusheng was fascinated by Li Yao's gaze. The latter seemed to sense the other party's gaze, and took out the glasses that had just been put in his pocket in embarrassment, wiped them on the corner of his clothes, and put them back again.After doing these actions, Li Yao raised his head and found that Du Yusheng was still looking at him.

Unable to resist coughing a few times, Du Yusheng finally came to his senses and scratched his nose with red ears. "Is the eldest sister inside alright?" Du Yusheng took an excuse to look inside for a while, and said, "Don't you need to go to the hospital again?"

Li Yao followed his gaze to look in, and the elder sister had obviously improved, and she was standing up and pacing slowly in the room.

"Our suggestion is to let her go to the system to check again. But she didn't say anything..."

Du Yusheng was puzzled and said, "Why don't you go?"

Li Yao shook his head helplessly and said, "As far as a doctor is concerned, sometimes your suggestion can only be a suggestion."

"There is depth."

Du Yusheng gave a thumbs up.

If it wasn't for Xiaobai staring at him stupidly, Du Yusheng really wanted to applaud Li Yao.His words sounded pleasing to the ear, unlike some experts who insisted on a few words, but still didn't understand the main point.In short, even when he spoke concisely, Du Yusheng felt comfortable.

Li Yao lowered his head and showed an elegant smile.

"Is Deputy Du's side going well?" Li Yao looked at the people who rushed over one after another and said, "I heard there is another murder case?"

Du Yusheng nodded, "Killing and burning corpses is so bad."

Li Yao said politely: "You usually work very hard, you have to face everything."

"We're all the same." Du Yusheng pointed to himself, then tapped Li Yao's chest, and said, "It's all about saving lives."

Li Yao froze for a moment, looked at the fingers on his chest, then stepped back slightly to avoid the touch of the fingers, Du Yusheng was a little embarrassed, and stiffly withdrew his fingers and smiled slightly hurt.

"Are you annoying me?"

Du Yusheng couldn't help asking.

Xiaobai suddenly realized something nearby, and slapped Du Yusheng's thigh.Only then did Du Yusheng realize what he said, and his ears were red.Du Yusheng may usually bring his brain to work, but whenever he encounters some emotional matters, he puts his brain in his pocket and forgets to take it out.

Du Yusheng didn't figure it out himself, so he only met Li Yao a few times, so he dared to say anything.

Fortunately, Li Yao didn't seem to hear what Du Yusheng said clearly, and his face was still calm, with a moderately distant smile.

At this stall where the air was frozen, the little nurse on the ambulance ran over and said a few words next to Li Yao's ear.

Du Yusheng understands lip language, even if he can't hear, as long as he sees your mouth shape, he can know what you said.Looking at the two people intently, in short, Huandao Hospital asked Li Yao to go back to change shifts, and the ambulance had to wait for a while before leaving. This place is remote and it is not easy to take a taxi. Li Yao's eyebrows furrowed tighter and tighter.

He looks good when he smiles, and a good-looking person should laugh. Du Yusheng doesn't like to see him frowning and troubled.

"Take my car and go."

Li Yao looked up at him in astonishment, and confirmed, "What did you say?"

Du Yusheng pointed to Bentley not far from the street and said, "I said you can take my car and go, we're just going back."

Li Yao looked at Du Yusheng for a while, and when he was about to open his mouth, Du Yusheng interrupted him immediately.

"You can treat me as a fast train."

Speaking of this, Li Yao should never refuse again, Li Yao thought for a while, nodded, and agreed.

Li Yao was changing his white coat and putting on his own clothes. Du Yusheng stood not far away and looked at him. The phone in his pocket was getting tighter and tighter. Xiaobai squinted at Du Yusheng with his elbow. he.

"Brother Yu..." Xiaobai reminded, "You are not quite normal today."

Du Yusheng didn't speak, but expressed the meaning of 'what's not normal' with his eyes.

"Why do you care so much about him?" Xiaobai imitated a bit, and said, "The eyes are almost growing on him."

Du Yusheng sniffed and said in a bad breath, "I fucking want to know too."

It's over, it's over, Du Yusheng murmured in his heart.

Xiaobai went there to drive the car over first, Du Yusheng saw that Li Yao was about to change clothes, and walked a few steps over there.Li Yao's hair was a little messy because of changing clothes, and his clothes were a little wrinkled as if he was in a hurry, which made this person a little more fussy.

Du Yusheng walked up to him and said, "Okay?"

Li Yao turned back and tugged at his clothes and nodded, "I'm sorry to trouble you."

"No trouble, I'm on my way."

Du Yusheng walked behind and pointed to Bentley at the end of his street, signaling Li Yao to go forward, and followed him to watch his back.The crime scene of murder and cremation is on the right hand side, colleagues are coming in and out one after another, and a white ambulance is behind the left, but Du Yusheng seems to feel that there are only two of them on this road, the corners of his mouth are getting wider and wider. big.

I don't know why, but I really want to laugh.

This is an urban-rural fringe area, not very developed. Du Yusheng's Bentley parked at the intersection is particularly eye-catching.

"Luo Daheng's case doesn't seem to have any impact on Dr. Li's life..."

Li Yao looked at Du Yusheng with a slight chill on his face.

"What influence should I have?" He said: "I can't sleep, or should I eat well? It has nothing to do with me. How many times do I have to say it to Deputy Team Du?"

Annoyed?

So lovely.

Du Yusheng touched his chin and changed the subject: "Don't call me that, my name is Du Yusheng, you can call me..."

"Adu?"

"..."

"Adu, hello."

"..."

Du Yusheng looked at the outstretched hand and didn't know whether to hold it or not.

Du Yusheng looked at Li Yao's slightly raised mouth and these two words came to mind.

Du Yusheng's Bentley exploded 30 seconds later, and it happened that the signal in the car was not good. As soon as Xiaobai started the car, he got out of the car and went outside to answer the phone. At the end, he called the two people who were walking and chatting to get in the car quickly.

When the distance between the car and the person was still five or six meters away, Li Yao suddenly grabbed Du Yusheng's arm. In my impression, he always had a polite smile on his face. This was the first time that Du Yusheng was on Li Yao's face. I saw a seriousness that I had never seen before.Du Yusheng's body was stiff for a moment, and he looked down at Li Yao's tightly gripped fingers. His strength was so great that his nails turned white. He just wanted to open his mouth to make a joke, but suddenly there was a loud bang from Xiaobai's side, and Du Yusheng's mind was buzzing. There was a sound, followed by a pungent burning smell that filled the nostrils.

Bentley was instantly surrounded by flames, and in less than a few tens of seconds, only a burning body remained.

For the first time, Du Yusheng felt that he had a face-to-face meeting with the god of death.

========

Du Yusheng returned to the bureau that afternoon.

Back in the game, Qin Yan was coming out of the laboratory. He had been busy in the laboratory all day, his hair was wet and almost stuck to the surgical cap, his rubber gloves were almost soaked in sweat, and he didn't know how many masks he had changed. With no time to wash his hands and change his clothes, Qin Yan took this equipment and ran into Du Yusheng who had just come back from the outside.

Without greeting Du Yusheng, Qin Yan looked behind Du Yusheng for a while.

He seems to bring back a person.

"It's Li Yao."

Xiaobai wiped the dust off his body in embarrassment, with lingering fears in his heart, he said, "It's thanks to him this time, otherwise we would have to burn paper for Brother Yu."

Qin Yan didn't understand, and watched the colleagues behind him take Li Yao into another room.Du Yu sank heavily on his boss chair with a thud, then picked up the boiled water left on the table yesterday, and drank it all in one gulp.

Du Yusheng was never afraid of death, but he was afraid that others would die because of him.

"Someone planted a bomb on Brother Yu's Bentley." Xiaobai explained, "It's just a little short." Comparing his fingers, he continued, "I'm a little short, too."

After hearing this, Qin Yan felt cold all over.

"The police are all around, who dares to do that?" Qin Yan added: "Who can do that." The latter sentence was more like a questioning.

Xiaobai shrugged.

"There is no monitoring, everyone is busy with their own business, our car is parked at the intersection, who can keep watching?"

Qin Yan looked at Du Yusheng, who didn't speak, picked up the half pack of cigarettes on the table, lit them skillfully, took two deep puffs, held the cigarette in the corner of his mouth for a few seconds, and then held the cigarette between his fingertips.He smoked fiercely, and the cigarettes burned out quickly. Du Yusheng didn't say a word, and kept looking at the four characters of "controlled experiment" on his computer.

"Let someone check it out. You must know what's going on." Qin Yan was wearing a mask, and couldn't hear clearly. He might feel the anxiety in his tone.

Xiaobai sat up from the chair and made a gesture to go.

"Sit down!" Du Yusheng interrupted him sharply, "I'll let you sit down!"

Qin Yan was puzzled.

Du Yusheng extinguished the cigarette in the ashtray, looked up at Qin Yan.

Qin Yan always thought that Du Yusheng's eyes were beautiful, and he could see to the end at a glance, but these beautiful pupils were completely black, exactly the same color as death.

"I know who it is."

Du Yusheng looked at Xiaobai, then at Qin Yan, and finally fixed his eyes on Xiaobai.

"I know who it is."

He repeated it again.

The second cigarette was held between his fingertips. Du Yusheng was about to light it, but he thought about it and put it back.

He raised his head and said, "Yo, I didn't look at you carefully just now." Du Yusheng looked at Qin Yan with a belated and apologetic expression.

His face changed quickly, and in a few seconds he returned to the foolish look he knew before.

"Are the results out?"

Qin Yan nodded.

"Just as you thought, Luo Daheng's used-up salbutamol did contain a high concentration of nitroglycerin."

Du Yusheng then asked, "Where's the toner on your thumb?"

"It's also the same as the ingredients in the toner cartridge."

Xiaobai didn't understand, and looked at the two of them with innocent eyes blinking.

"What do you mean?"

Du Yusheng still took out another cigarette and lit it.

This time he smoked slower.

"Luo Daheng met two people one after another that night, let's put aside these two people. We all have this common sense. When your printer can't print ink, take out the toner cartridge and shake it from side to side, and it can print again. But in this way, you will leave toner on your thumb. Therefore, one thing is certain now, that is, Daheng Luo must have opened the printer and checked the toner cartridge that night."

"..." Xiaobai said, "So?"

"Printers are electronic equipment, and electronic equipment is the easiest to accumulate dust. Luo Daheng had severe bronchial asthma during his lifetime. Dust is nothing to us, but to him?"

Du Yusheng's cigarette was held between his fingertips, the end of the cigarette was facing Xiaobai, and the burnt orange head was flickering towards Xiaobai, like a pair of eyes looking at him.

Xiaobai suddenly felt a little cold.
