Controlled experiment

What Du Yusheng said didn't seem like a joke.

He Shen was a little surprised, he stroked the bridge of his nose, and looked at his former cronies.

"Du Yusheng." He Shen said, "What on earth do you want to do?" Halfway through speaking, He Shen suddenly patted his thigh and reminded, "You're killing yourself, right?"

"What the hell are you talking about?" Du Yu gave He Shen a blank look, and said with a smile, "I heard that you have a house that was bought by your father, and it has been vacant since it was renovated?"

He Shen touched the watch Du Yusheng gave him on his wrist, nodded and said, "That's what happened."

"Success." Du Yusheng patted He Shen's thigh, and said with a smile, "Give me the key, lend me the key to live in for a while, and return it to you later, if you don't like it, you can choose any one in my house."

He Shen rolled his eyes and recognized the meaning of Du Yusheng's words.

"Not only do I lend you the house, but I also have to keep it a secret, right?"

Du Yusheng nodded, and shook his mobile phone in front of He Shen a few times.

"When I have figured out the time, you can send this message to that terminal." Du Yusheng lit a cigarette and said, "Aren't they all playing tricks on me? Don't they all treat me as a villain? Let's come here this time." Let's switch roles and see if you can be played by me once."

He Shen couldn't quite understand what Du Yusheng meant, so he could only nod in agreement.

After hanging out with He Shen in the bar for a while, Du Yusheng came out.

He glanced at his watch before going out.

It's three o'clock in the morning Beijing time.

Du Yusheng held the cigarette in his mouth between his fingers, and just now he was smoking in the small space in the private room. Now his body was covered with the smell of smoke. Du Yusheng himself felt uncomfortable smelling it, so he simply stood at the intersection, letting the wind blow, Wait for the smell of smoke to dissipate.

Taking out his mobile phone, Du Yusheng opened WeChat and looked at it. Except for Xiaobai's WeChat messages, they were all pushes from official accounts. With Du Yusheng's clumsy false statements, he was either detained or locked up in the police station, how could it be like this.

Du Yusheng squinted his eyes and looked at Li Yao's WeChat. Li Yao didn't have a circle of friends, and occasionally posted academic papers, and his professional words were longer than Du Yusheng's leg hair.

Thinking of this, Du Yusheng rubbed the phone in his hand.

When a cigarette was burned out, I saw a taxi over there.

Du Yusheng patted the smell of cigarettes on his body before getting into the car.

Originally, he didn't want to go home, but now Mrs. Du is not around the island. The old lady has not come back from a trip. Even if she goes back to the old lady now, there is only Du Yusheng alone. Du Yusheng could only go back to his own home.

It's really ironic to say that at that time, Du Yusheng moved all the way here because of Li Yao. Looking back now, his behavior of putting a hot face on a cold butt was really asking for trouble.Du Yusheng stood downstairs looking at the glass of his house and sighed.

Want to smoke another cigarette.

Du Yusheng squatted at the flower bed next to the community, and took out a cigarette from his pocket.

While holding a lighter to start a fire, Du Yusheng unexpectedly saw Li Yao coming out of the unit building.

Subconsciously glanced at the watch on his wrist.

It's four o'clock in the morning, the sun is almost rising, what is he going to do?

Li Yao, who was wearing a gray coat, opened the car door and got in, then slowly started the car.

Du Yusheng slowly took a puff of cigarette and watched Li Yao leave his field of vision.

He let out a heavy breath, and Du Yusheng suddenly remembered that when Xiaobai was just transferred, he helped him keep an eye on Li Yao. Du Yusheng still remembered that Xiaobai clearly said that he saw Li Yao coming out of the house and leaving the community Why did Du Yusheng see Li Yao at home when he picked the lock to get in.Thinking about it now, what Xiaobai saw at that time should be his younger brother.

If I had used my brain back then, I'm afraid I would have seen through that there were two people in Li Yao.

This time, Du Yusheng didn't want to take any risks.

He took out the cell phone in his pocket and made a call.

"Hello." The little nurse who answered the phone had a sweet voice, "Hello, nurse station."

Fortunately, when I secretly left the inpatient department that day, I wrote down the phone number of the nurse's station.

"Hello, hello, hello." With a cigarette in his mouth, Du Yusheng said with some slurred words, "Is Dr. Li Yao in?"

"The outpatient clinic is at eight in the morning. This is the inpatient department." The nurse who had been working all night was so exhausted that she almost didn't bother to explain, and said, "Registration starts at eight o'clock. If you are in a hurry, you can make an appointment online or through the registration machine."

"No, no." Du Yusheng stopped the nurse who was about to hang up the phone, and said, "I made an appointment with him to go to the hospital to find him later, is he there? I don't have his mobile phone number, and I don't want to make a trip in vain, so late."

"An appointment? Then you wait a moment."

Du Yusheng heard the nurse yelling on the other end of the phone: "Is Dr. Li there? Is he on the night shift or outpatient today?"

Two minutes later, the nurse picked up the phone again.

"He has an emergency room today. I just called him and he will arrive soon."

"Success, then I'll look for him later, thank you."

Du Yusheng looked at the darkened windows of Li Yao's house and heaved a sigh of relief.

The cigarette in his mouth was about to burn out, so Du Yusheng extinguished it in the trash can next to it, and then pressed the elevator.

======================

When was the last time you came to Li Yao's house?

At that time, it seemed that it was Chen Xin's case, and it wasn't too long after all.

But Du Yusheng felt like several years had passed.

At the door, he opened the door of Li Yao's house deftly. His house was pitch black. Du Yusheng closed the anti-theft door with his backhand, and then turned on the light in the living room.

Looking around, there was no one in the empty room. It looked like Li Yao had just left, and there seemed to be a smell of him in the air.Standing in the middle of the living room, Du Yusheng suddenly felt a tightness in his throat. He can still remember the first time he came to his house. Li Yao was wearing pajamas. He looked at himself who unlocked and entered the door calmly. On the other hand, he was very embarrassed. .

How can he be so confident in everything he does?

Knowing Li Yao's identity, Du Yusheng finally had the answer.

Li Yao's home is almost the same as when he came last time, it is still clean and monotonous.

Du Yusheng sat on the sofa in the living room and opened the drawer under the coffee table. Inside was a drawer full of glasses.

In my impression, Li Yao seldom wears glasses.

Du Yusheng thought that the owner of these glasses should not be Li Yao.

Next to the living room is the bedroom, and Du Yusheng slept in it. Now that I think about it, I am really afraid, what if I die here.Du Yusheng stood against the wall of the bedroom for a while, his eyes could just see the clock on the wall.The style of the clock is very ordinary, the one in the classroom in high school, except for the numbers and the few needles, there are no other extra decorations.Du Yusheng stood under the clock and looked at it. He didn't know which muscle he was stuck on, so he stepped on the stool and took off the clock.

Generally, things hanging on the wall are tall and not used frequently, so it is easy for people to ignore them when cleaning.

Logically speaking, the clock is like this.

But this clock is very strange, the dial is dirty, the back is not clean, only the knob to adjust the time is clean.

Du Yusheng was stunned.

Under what circumstances do people typically turn this knob?When the power of the clock is low, stopped, or it is broken, the time needs to be adjusted.However, the battery replacement position of this watch is also dirty, only the knob is clean.

Why has this watch been touched?

Du Yusheng suddenly had a bad association. He lived here that night, and Li Yao woke him up halfway. Could it be that the watch was touched that night?

After re-hanging the watch on the wall, Du Yusheng took a photo of the clock.

Next to the bedroom is a study room. To be honest, Du Yusheng has never been here, although he has been here many times.

In addition to the necessary furniture, there is a large bookcase in the study.

Du Yusheng glanced at it, and there were all English books that he couldn't understand, and occasionally there were a few high-end books that he could understand.Pausing in front of the bookcase for a while, Du Yusheng opened the drawer under the bookcase.

The first thing I saw were a few brochures of medical companies, and underneath was a kraft paper document bag.

Du Yusheng detoured the thread ball above.

There is a thick stack of documents, the top one is the photo pinned with paper clips, the first is the group photo of seven people, followed by two photos, these two photos were seen by Du Yusheng, and they were given to Li Yao by himself.These two photos were caught in the book that Luo Yang lost in the casino car at that time. At that time, Du Yusheng wondered why he only crossed one of the two photos of the same person. .Now everything makes sense, because the other one belongs to Jing Mo.

Thinking of this, Du Yusheng scolded himself.

Should have seen it earlier.

Immediately below the photographs are several individual profiles.

Du Yusheng was stunned for a moment, he saw his file.

It includes date of birth, household registration, elementary school, high school, university, various awards and punishments during school, criticisms in the police station, evaluations, and even his own constellation and blood type. There are some trivial things that Du Yusheng himself can’t remember. It was recorded clearly.

The last one has the expiration date for this file.

Du Yusheng took a glance, and he subconsciously opened the phone calendar to compare the photos.

I knew Li Yao after Luo Daheng's case, but the above time was much earlier than this time period.In other words, Li Yao knew himself a long time ago.

Du Yusheng had a bad premonition. Although he begged the Bureau to handle the transfer from the grassroots because of the old man's accident, but now it seems that this matter has something to do with Li Yao?

In other words, does the old man's death also have something to do with Li Yao?

This thought made Du Yusheng feel chills.

The several files pressed below belong to the seven people in the photo.According to the size, Li Yao coded them together so that they wouldn't be together.

Du Yusheng took two photos and stuffed these documents back.

Then he went through the other two drawers, including Du Yusheng's professional textbooks, but found nothing of value.

Du Yusheng walked back to the living room and sighed. Sure enough, as Li Yao said, there is nothing about his brother here. If there is, it is that Li Yao's face is related to his brother, and that one Glasses in the drawer, nothing else.

Originally thinking that something would happen to Li Yao here, Du Yusheng turned off all the lights in his house, and before leaving, he was still thinking about getting some monitors.

Then, in the dark room, Du Yusheng heard a knock on the door.
