Controlled experiment

Back in the car, Du Yusheng told Xiaobai about it.

Xiaobai's opinion is similar to that of Du Yusheng.

"We have surveillance video, what's the point of his lying?" Added: "When we are stupid?"

The corners of Du Yusheng's mouth drooped slightly, "Yeah, what's the point, and I'm still pretending to be serious."

"So? Brother Yu?" Xiaobai pointed out the window with his finger, "What do you think?"

"What do you think."

This is an affirmative rhetorical question, Du Yusheng smacked his mouth and glanced in.

Huandao Central Hospital is the largest and best hospital in the urban area. No matter in terms of medical facilities, doctor equipment, or infrastructure, it is one of the best. Even the glass of the outpatient building is wiped clean.Du Yusheng is nothing special, but his eyes are one of the best in the team. From the angle of the parking space, he can just see the corridor on the second floor.He saw that person at a glance. Li Yao came out of the consulting room and did not get off work. He was still wearing the white coat, but now he unbuttoned it, revealing the light-colored T-shirt inside. It looked like a medical drama. , A little nurse came outside the door, and said a few words to him, Du Yusheng watched Li Yao bent down to sign something in the little nurse's book, and then bowed politely, without thinking about it, that guy must be polite again Although it was the first time I saw a decent smile, Du Yusheng thought he had figured out this little doctor.

Of course, this is just what he thinks. Later generations commented on Du Yusheng's self-confidence as evil.

"Brother Yu?"

Xiaobai called out twice before Du Yusheng came back to his senses.

"Brother Yu... what are you thinking about?"

Du Yu gave him a blank look, "Okay, let's take it back to the team for interrogation."

Xiaobai was dumbfounded, "...Just take it back like this?"

"Otherwise?" Du Yusheng sneered, "Bang gongs and drums, put up lanterns and streamers, and bring them back?"

Xiaobai really wants to ask a question, why don't you call and ask for instructions?After thinking about it, this is Du Yusheng.

After waiting in the car for three seconds, there was no movement from Du Yusheng. Xiaobai didn't understand, and blinked and watched.

"What are you talking about, Fei Te?" Du Yusheng scolded, "I asked you to bring him back."

"...I'm not the leader... I'm going to use it as an ass." Xiao Bai muttered in a low voice.

Du Yusheng has his own plans in mind, this Li Yao looks pleasing to the eye, so he must not leave a good impression in front of the world.

Xiaobai originally thought that he would be pushed back by Li Yao, and he was ready for it. Who knew that Li Yao looked at Du Yusheng's car outside the window, and his eyes met. Xiaobai obviously heard Li Yao's words. With a chuckle, he was brought back to the bureau so easily.

As soon as he returned to the bureau, he ran into Qin Yan in the corridor. He had just finished dealing with the matter in hand, and saw the two of them coming back.

"The case has been solved?" Qin Yan said with a smile, "Look at this complacency?"

Xiaobai shook his head: "No, I brought back a suspect who is about to go to interrogation."

Du Yusheng stretched out a finger and said with a smile: "He, said, lied." Turning to Xiaobai, he said, "Bai, take the surveillance video."

This Du Yusheng is very lazy, and the people under his command who can interrogate him never bother himself, but for this Li Yao, Du Yusheng wants to ask in person. Du Yusheng couldn't figure out why someone like this would tell such a low-level lie.

Everything was ready, Du Yusheng pushed open the door of the interrogation room, took a laptop, and walked in alone.

Li Yao originally had his eyes closed, but he opened them slowly when he heard the movement, and smiled politely at Du Yusheng.

He was wearing a light-colored t-shirt with a dark coat on the outside, taking advantage of this person's complexion, like a scholar in an ancient TV series, with a bit of a literati air, but without the old-fashioned and pedantic of a literati.Du Yusheng's brain is not good, he only thinks of the word "good-looking".

"Doctor Li doesn't seem nervous at all." Du Yusheng sat down on the table in the interrogation room and smiled.

Li Yao shook his head and smiled, "I don't know why I should be nervous?" He looked around, "Is it because you are at the police station?"

Du Yusheng rubbed his fingers, pretended to stand up casually, and leaned against the single-sided glass at the back to watch the expression on Li Yao's face.

"I heard that Dr. Li went abroad with his parents when he was very young, and then his parents immigrated, but you returned to China alone when you were just in high school, and did not emigrate with your parents." Du Yusheng paused for a moment and continued: "Your parents really Don't worry, you are so young, why don't you immigrate with your parents. A family of three."

Li Yao looked into Du Yusheng's eyes without any discomfort on his face, as if what Du Yusheng said was not about his family.

"Parents have their own considerations. I can't decide anything."

Du Yusheng nodded thoughtfully, "Then you haven't been in touch with them since you returned to China when you were first promoted, right? Free-range care?"

"..." Li Yao laughed softly, "Does this have something to do with the case?"

Du Yusheng walked back to the table and shrugged indifferently.

"Just chat casually, just get to know Dr. Li."

Enough of the bullshit, it's time to talk about something serious.

"Dr. Li just told me in the hospital why you were there on Thursday?" Du Yusheng scratched his head, "You see, I have a bad memory."

"I went home after surgery." Li Yao repeated, "I didn't see Mr. Luo that night."

"Yo, that's weird then."

Du Yusheng opened the notebook on the table, pressed the start button, and the screen turned to Li Yao.The video on the computer screen is the night of Luo Daheng's death, the surveillance video around the villa, the surveillance equipment in the high-end community is not bad, and the shooting is very clear. Li Yao quickly appeared in the video. Du Yusheng looked at Li in the interrogation room. After a little inaudible sigh on Yao's expression, Du Yusheng didn't see any disturbance.

"Look at how clear the shot is." Du Yusheng closed the computer, tapped the screen, and looked at Li Yao with great interest.

Li Yao lowered his head and smiled, "After watching your video, I realized that I might have misremembered."

Du Yusheng couldn't laugh anymore.

"I didn't go home from surgery on Thursday, it should be Wednesday." Li Yao raised his head, "I did meet Mr. Luo on Thursday, and even went to his home."

"...You didn't remember until here?" Du Yusheng tapped his fingers vigorously on the table, "Isn't it a coincidence?"

"Cory has been very busy recently, so it's normal if I remember wrongly?"

Du Yusheng glanced at the one-way glass.

"Then tell me, why did you go to see Daheng Luo?"

"Routine inspection." Li Yao said, "I'm his personal doctor, and I'm going to check his current condition." As if he already knew what Du Yusheng was going to ask next, Li Yao continued, "Mr. Luo was no different from usual that day. After saying a few words to him, I left, and before I left, I also told him not to stay up late, and pay more attention to rest. I was delayed... for no more than 15 minutes."

"15 minutes?" Du Yusheng said, "Remember so clearly? Did you count by the watch?"

Li Yao smiled faintly, "As doctors, we have a strong sense of time and professional habits."

"No more? You didn't do anything else? Think about it." Du Yusheng crossed his legs in front of Li Yao.

Li Yao's words were all clichés, nothing dry, just like lines memorized in advance.

"That's all." Li Yao seemed to be thinking seriously, "After that, I will go home. You have monitoring, you can adjust it to see if I came home on Wednesday night, and see if I am on Thursday. Went there tonight."

"...You don't need to say that! We will see it ourselves." Du Yusheng glanced at the one-way glass, sulked, opened the door and walked out.

Qin Yan and Xiaobai stood outside to watch the conversation between the two just now, and they really heard it.Du Yusheng passed by, and the three of them exchanged glances, guessing that the two of them didn't think about anything.

"What do you two think?"

Xiao Bai watched Li Yao inside, closed his eyes and sniffed again.

"This grandson made it clear that he was lying, and changed his words after seeing the surveillance."

"... Open your mouth and you will be your grandson." Du Yusheng slapped Xiaobai on the head, "Who is your grandson?"

Don't even look at who to scold.Du Yusheng turned his head to look at Li Yao, knowing that the other party couldn't see him, but Du Yusheng couldn't help but glance there, why did he suddenly become a bitch.

"He's lying. And he's very calm." Qin Yan looked at Du Yusheng and said, "Leaving his dna and fingerprints as a routine, I'll take them to the laboratory for backup."

Du Yusheng nodded, he also meant the same thing.

At first I thought I could come back and ask something, but in the end it was all for nothing.

Nothing was accomplished, Du Yusheng's complexion was not very good, he wanted to wait for the time to let him go back, but it didn't work out, he answered a phone call before leaving work, in short, there is a patient in charge of Li Yao in Huandao Central Hospital today When something happened, I asked someone to go back for consultation. This patient was always in charge of Li Yao, and it was critically ill. No one dared to take it, so I called the bureau.

After hanging up the phone, Xiaobai and Du Yusheng looked at each other.

After a long time, Du Yusheng sighed, raised his chin and looked at Xiaobai, "Go, let him go."

Xiaobai felt that he was really unlucky, and all those who ran errands and those who were scolded had to go by themselves.

When Xiaobai came back, he thought he could get off work, but was stopped by Du Yusheng again.

"Find someone to follow him and see where he goes."

After explaining, Du Yusheng sat in his office and turned on the computer.

The computer was recently set with a new wallpaper by himself, and he was rewarded for a group photo. Du Yusheng opened a photo on the desktop, and the anonymous email sent the twins, and Du Yusheng saved it in the computer.This photo was more like a prank, but Du Yusheng was disturbed in his heart and always thought about it.I stare at this photo in my free time.

Controlled experiment.

What exactly does this sentence mean.

Du Yusheng had a hunch that even if the murderer was caught, this mystery might not be solved.

After an unknown amount of time, Xiao Baina called.

"Brother Yu, Li Yao didn't go to the hospital." Xiaobai continued, "He went home."

This is normal, and it is very likely that Li Yao has to go home to get things.

Sure enough, 5 minutes later, Xiaobai called again, "Brother Yu, he came out again, should I still follow?"

"Don't follow." Du Yusheng said: "You go home and rest, I will do the rest."

After hanging up the phone, Xiaobai didn't even want to understand what Du Yusheng said and what I was referring to.

Du Yusheng grabbed his coat from the back of the chair and put it on his body, and went out with the car keys on the table.

This Li Yao was too suspicious, Du Yusheng wanted to take a risk.

Li Yao's home is not far from the police station, in a district, if there is no traffic jam, you can drive there in half an hour.It’s late at night, and the roads are not congested. Du Yusheng owns a classic car. The reason why it is called a classic car is that it is really old. The glass and doors are all rear-mounted. If you look closely, you can see the color difference, and the seats are also Most of them were rough, and most of them were edged, and the replaced door still had a hand window. Mr. Du said that you should not be too high-profile when you go out. Du Yusheng listened to it and got a car that even the repair shop couldn't handle.

Although Li Yao's community is not a noble area, it is also one of the newly opened properties. Du Yusheng's ten-hand car parked in the yard is particularly eye-catching.The owner of the car opened the door and walked down to look at the window of Li Yao's floor from a distance, it was pitch black.

Hope to find something tonight.

Li Yao lived on the tenth floor, and Du Yusheng waited by the elevator for a while. This is a new community with only two families on each floor. It is quiet and the corridors have a lot of space.

Standing at the door, Du Yusheng took out the tools in his pocket and fiddled with the keyhole.

When he was in school, Du Yusheng couldn't do anything else. He was one of the best at doing these things. The professor said that there was no lock or door that Du Yusheng couldn't open.

In a few seconds, Du Yusheng opened this valuable anti-theft door intact, and put the tool back in his pocket. Du Yusheng was quite proud.Li Yao's house was dark with no lights on, and there was a faint fragrance in his house. Du Yusheng closed the door behind his back and fumbled for the switch on the wall.

The warm yellow light is not dazzling, and there are very designed lamps on the ceiling. It seems that the owner has put a lot of thought into it.

Du Yusheng's eyes gradually moved from the lamp to the bottom, and then he stopped.

He wanted to dig Xiaobai out of the house and scold him bloody from beginning to end.

Because he saw Li Yao in dark blue home clothes standing in the living room holding a transparent glass.

The person who Xiaobai said had left home, the person who was called by the hospital for consultation, was standing in front of him.

Provocative things, breaking into private houses, these eight words suddenly appeared in Du Yusheng's mind.

Not to mention being the captain, Du Yusheng suddenly felt that he couldn't even keep the vice-captain.

"...Hey, I opened the wrong door." Du Yusheng felt at a loss for the first time, he withdrew his hand in embarrassment, stepped back a few steps and pointed at the door behind, "Oh, Doctor Li, do you live here? What a coincidence , I live opposite."

A lie that can be easily debunked.

Li Yao didn't seem to intend to expose this clumsy lie, nor was he flustered by his sudden entry, as if he knew there would be an unexpected visitor tonight.Du Yusheng saw that he took the cup in his hand and took a cup of white water in a leisurely manner, and put it on the expensive glass coffee table.His house slippers are dark green, they look thick, they must be very warm to wear, Du Yusheng thought.

"Neighbor?" Li Yao said with a well-bred smile, "I just moved here not long ago, I didn't expect us to live so close."

Du Yusheng laughed a few times, "Isn't it? It's very close, and you can see it when you open the door... I didn't bring the key, just, you know, we need to know everything in this industry, and unlocking is also a compulsory course. Go upstairs I didn’t even notice when it was dark, I opened the wrong door.”

Li Yao pursed his lips and smiled, "You really surprised me. You can come to my place next time without the key."

Du Yusheng didn't know what to say, so he nodded, thinking in his heart that he should never go to the bureau to report his breaking into a private house. Originally, he was under the pressure of the case recently. After resting for more than half a month, even with the title of Young Master of the Du family, he couldn't stand it anymore.

After walking a few steps back, Du Yusheng suddenly remembered something.

"...Didn't Dr. Li say he was going to the hospital?"

"I don't need to go." Li Yao put the cup of water aside with ease, sat on the sofa and looked at him, and said, "I just told them on the phone in the car, and I don't need to be rescued. I'll go again." He added: "After several night shifts in a row, I'm also tired and want to sleep well."

Now that the words have come to this point, Du Yusheng has no reason to stay any longer.

Before leaving, Du Yusheng apologized and looked at the entrance. There was a bunch of keys on the table in the entrance. The keys were exquisitely made, like a house number.

Du Yusheng also has one of these things. The key to Mr. Du’s villa is like this. In other words, the key to Luo Daheng’s villa is also in this shape. No, with this key, Li Yao can enter and leave his home at will.

Coming out of Li Yao's house, Du Yusheng took the elevator all the way back to the car with his ears red.

He took out his cell phone and made a call. Xiao Bai was woken up just after falling asleep.

"What the hell kind of eyes do you have?" Du Yusheng scolded: "A 30-year-old has the eyes of an 80-year-old. You can't tell who is who. Li Yao is fucking at home, you know? .”

In one sentence, three fucks are enough to show how angry Du Yusheng is now.After scolding for a few minutes, Xiaobai understood and scratched his head in confusion.

"You obviously saw him come out of the house."

"You see a fart." Du Yusheng said angrily: "By the way, buy the house opposite Li Yao's house."

"..." Xiaobai laughed dryly, "Brother Yu, do you rich people spend so much money?"

"Do you still have the guts to say it? If it weren't for your perverted eyes, I would be guilty of it. If you say one more word, I will record whether you heard it or not!"

"Yes, I'll do it right away." Xiaobai thought that he would not be able to afford the house price in that area even if he lived to 99.

After hanging up the phone, Du Yusheng pushed down the car window and looked at Li Yao's floor. This Li Yao was very strange. Everything he said was a perfect lie. Du Yusheng couldn't guarantee whether it had anything to do with Luo Daheng's death.As Li Yao said, he is a family doctor who counts on Daheng Luo for his salary, so there is no reason to kill him, but why all the relevant evidence points to him most directly.Du Yusheng lit a cigarette, put it in his mouth, and slowly started the car.

He figured he needed some sleep too.
