Controlled experiment

On Sunday night, Xiao Bai returned home very early.

He hasn't been sleeping well recently, and it's hard to fall asleep. Even if he falls asleep, he always wakes up in the middle of the night.

Recently, Du Yusheng always tried to test himself with a few words when he was unprepared, which made Xiaobai very nervous all day long.He didn't know why Du Yusheng would suddenly associate himself with Luo Yang, and he didn't know why he would guess that he and Li Yao knew each other.Xiaobai consciously did nothing flawless, unless Du Yusheng was spying on him and listening to his mobile phone, otherwise he would not know such details.

Thinking of this, Xiaobai took out a new mobile phone from his drawer, put the SIM card in it again, and turned it on.

Then I took off all the clothes from top to bottom, and the clothes were still rolled up in the trash can outside, and I went into the bathroom to take a shower.

It is better to believe what is there than to believe what is not, Xiaobai does not want to take risks.Xiaobai's home is not in the downtown area, it is a very old community, and the residents in the community are all elderly people, and in the middle of the night, there are very few residents who are lit here.Xiaobai sat on the sofa in his living room with a towel wrapped around him, without turning on the light, staring at the large floor-to-ceiling windows in a daze.

After taking a shower, it refreshed me. Xiao Bai took a bottle of drink from the refrigerator, opened it and drank it down.

The cold water entered his throat and his body shivered. Xiao Bai cursed and closed the refrigerator door.

Li Yao's call came 5 minutes later.

Xiaobai and Li Yao have a tacit understanding, unless it is an urgent matter, it is best not to meet, let alone make a phone call.Li Yao is a cautious person, Xiaobai looked at the number on the caller ID and felt that something happened to Li Yao probably.

"Doctor Li." Xiaobai said, "I'm alone at home. Tell me what you want."

Xiaobai is also a smart person, and he explained the occasion and surrounding environment in one sentence.

The signal on Li Yao's side is a bit weak, and the sound is also very noisy.

"Xiaobai, I need your help here." Li Yao continued: "It is 02:30 in the morning, and Du Yusheng is sleeping alone at my house. Do three things. The first thing, you go to the bedroom where Du Yusheng sleeps, find the watch on the wall, and adjust it to the same time as normal. The second thing, you go downstairs and buy two freshly baked breakfasts Put them on the dining table in the living room, and you have to make Du Yusheng think that I left the house after breakfast. The last thing, you put on my clothes and pick up the car from the surveillance video downstairs, put the car Parked in the underground parking lot of Huandao Hospital. It is less than four hours since you left home. Although Du Yusheng fell asleep after taking medicine, he may wake up in the middle at any time. Once he finds out that you are in my house, you……"

"This matter is my own idea, and it has nothing to do with Mr. Li." Xiao Bai took a deep breath, clenched the iPhone in his hand, and interrupted Li Yao.

Li Yao was very satisfied with Xiaobai's answer, and reminded him: "It's less than four hours, you have to hurry up."

Hanging up the phone over there, Xiao Bai took another deep breath.

Turning on the alarm clock on the Apple phone, Xiao Bai set a three-hour countdown for himself.

It takes at least half an hour to go from home to Li Yao's home, and there are only two hours left in that time. Xiaobai touched the water droplets on his face, picked up the jacket and sweatpants on the sofa, and quickly Put it on your body.He is usually a person without a car in the bureau, and the car in the parking lot is also in someone else's name. Even if he saw it on the surveillance video, he couldn't find anything. Looking at his face in the mirror, Xiaobai felt that there was only one thing left now, a race against time.

Xiaobai and Li Yao have known each other for many years and trust each other, but this is indeed Xiaobai's first visit to Li Yao's house.

Before coming here, Xiaobai received various monitoring maps of Li Yao Community. If he could hide, he would avoid it.Before leaving, Xiaobai deliberately chose a piece of clothing without a logo on it, so that no character traits can be seen.

The little white man was standing in the living room of Li Yao's house, it was already a quarter past three in the morning.

The lights in his house were dark, and Xiao Bai used his fingers to open a small crack on the door of the bedroom.

There was no sound of speaking, only the sound of Du Yusheng's even breathing, Xiaobai heaved a sigh of relief, and walked sideways into the bedroom.

Just like what Li Yao said on the phone, the clock on the wall was several hours behind the accurate time. Xiao Bai took it off and adjusted it, then put it back again.

Du Yusheng was still asleep, breathing heavily, and had no intention of waking up at all.

Xiaobai laughed, and said to himself that you are still in the mood to sleep, I will just shoot you in the head now, and you will not know who killed you when you die.

Comparing his hand to the shape of a pistol, Xiaobai made a gesture on Du Yusheng's head, then smiled, turned and left.

Then he changed into Li Yao's clothes and drove to the underground parking lot of Huandao Hospital.

After finishing all this, Xiaobai sent a message to Li Yao.

Li Yao was on the way back with Zhuang Hao when he received the text message. Zhuang Hao was driving fast, for fear that he would miss the time when Du Yusheng woke up. Li Yao received the text message telling Zhuang Hao to send him directly to the roundabout. Already got someone else to do it.

Zhuang Hao looked at Li Yao in disbelief.

"Are you done?"

Li Yao nodded with a long sigh of relief, and said, "Jing Mo didn't give me a chance, so I can only create some alibi for myself. He knows that Du Yusheng treats me... as long as Chen Xin's death has something to do with me , Du Yusheng will definitely keep his eyes on me, why not ask the person involved to provide me with this alibi, he will never doubt himself." Zhuang Haoen said, saying that your heart is really dark.

==== Li Yao recalled everything Xiaobai had done in his mind, and the corner of his mouth slightly raised an arc.

"What did you just say?" Li Yao frowned and said, "You said someone killed Chen Xin wearing my clothes?"

Du Yusheng nodded and said, "I can't figure it out either. Have you offended someone recently? Or did someone suspicious come to you before?"

Li Yao suddenly laughed.

"Suspicious person..." Li Yao pointed to Du Yusheng and said, "It's you."

It was rare for Li Yao to make a joke, and Du Yusheng also smiled.

Arms crossed on Li Yao's desk, Du Yusheng rested his head between his two arms. With the help of the small yellow desk lamp at this height, Li Yao could just see Du Yusheng's facial features at close range, without impurities and with a smile Its owner is looking at Li Yao blinking.

"...Tell me, why are all the recent incidents aimed at you?" Du Yusheng rubbed his chin on his arm, and said, "It's too dangerous, I have to move to a new home quickly to protect you safety."

Li Yao glanced at him, and thought that it would be good if you take care of yourself.

"I don't think this suspect is coming for me." Li Yao pointed to the door of his office, and said, "My office is at the end of the corridor, and the monitor can't see it, no matter whose office it is , the suspect will choose to take a piece of clothing in this room, no matter who the owner of the clothing is."

This statement is not very far-fetched, Du Yusheng agreed.

"Chen Xin is the hospital you billed to live in." Du Yusheng said: "What's wrong with him? Now that the forensic results have not come out, it cannot be ruled out that he died suddenly due to illness."

Du Yusheng looked at the bowl of beef noodles that Li Yao kept stirring in Li Yao's hands. He kept stirring the noodles, but Li Yao didn't eat a single bite.

"Pain in the precordial area for two months." Li Yao clicked the mouse to look at the medical records on the computer screen, and said, "I did not find any organic problems after taking the electrocardiogram. I didn't suggest him to be hospitalized at first, but He strongly demanded, and the result of the report card was too different from his main complaint, so I was worried that he had other primary diseases, so I admitted him to the hospital."

This reason is reasonable.

Du Yusheng scratched his cheek, staring at the bowl of beef noodles that was getting cold.

"Do you know Chen Xin?"

Li Yao shook his head and said, "I only know that he is a car dealer."

Du Yusheng sent a WeChat message, which was sent by a colleague in the same group. The general content was that Chen Xin's family members, that is, the wife who had just had a trouble in the hospital, had been invited to the bureau, and someone would be arranged to ask relevant questions later.Du Yusheng replied with a word of kindness, and then sent a message asking them to check Chen Xin's relationship.

There is no result from Qin Yan's side yet, and Du Yusheng has nothing on hand except the monitor wearing Li Yao's clothes.

Du Yusheng scratched his nose and stood up, looked at Li Yao and said, "Chen Xin's ward is upstairs, why don't you go and see it with me?"

Li Yao laughed awkwardly and said, "Isn't it appropriate?"

Du Yusheng shook his head, "When it comes to hospitals, you are more familiar than me."

===

Chen Xin's ward has been cordoned off. Not only that, in order to prevent other patients or people from the hospital from entering the ward by mistake, martial law has been imposed on the lower half floor, from Chen Xin's ward to the next ward. After the door separating the ward, there were only Li Yao and Du Yusheng on the entire floor.

No one else has entered Chen Xin's ward except for the evidence collection this morning, and the scene remains as it is.

Du Yusheng picked up the shoe cover on the side and handed it to Li Yao.

"Have you been to Chen Xin's ward before?"

Du Yusheng turned on the light at the door of the ward.

"I've been here a few times during ward rounds." Li Yao walked to the side of the hospital bed, and continued: "But this is the first time that there is no one in this room."

The general outline of Chen Xin's position was drawn on the hospital bed. Except for the depression, the bed surface was very flat. Li Yao noticed this and bent down to look closely at the bed surface. Chen Xin did not die of natural causes.

"I felt weird when I came here in the morning." Du Yusheng opened Chen Xin's closet to Li Yao with his gloves on, and said, "He seems to be staying here in a hotel, and he even prepared three bottles of shampoo."

Li Yao laughed dryly.

"How did he die?"

Du Yusheng sighed, and said: "It's strange, he didn't have any scars all over his body, he seemed to be asleep, there was no sign of a fight in the room, and the murderer seemed to have been prepared for a long time, he even dealt with the footprints on the ground, just It’s like a gust of wind that blows over and then disappears.”

Li Yao picked up the project list on Chen Xin's desk and looked at it. It was obvious that he was still working in the hospital and was still working hard to make money for his career.

There were several pairs of Chen Xin's shoes on the lower shelf of the closet. Li Yao opened them one by one, and then turned around to look at the soles of these shoes.The shoes he brought were basically worn this season, and most of the soles were clean, except for one pair.

Li Yao rubbed the dirt on it and said to Du Yusheng, "It seems to have some red dirt on it..."

Du Yusheng's heart skipped a beat. He had only seen red soil in one place so far, and that was Daheng Luo's villa.

Could their deaths be related to each other?

Du Yusheng scratched his head, unable to understand.

The door of Chen Xin's ward was the vent, and Du Yusheng looked up at the vent.

The air vent was square and square, exactly the size of an adult. Du Yusheng moved a chair and stood under it, and took off the ventilation hood with gloves on.It was a little dark inside, so Du Yusheng turned on the flashlight of his mobile phone and took a picture inside. When a beam of light shot past, all he could see was dust.

Du Yusheng couldn't help but sneezed, he found a problem.

The dust is all in the air, and the walls of the vents are not so dirty.

Not only that, Du Yusheng also found a small half-black circle inside.

Mrs. Du bought aromatherapy for him before, and Du Yusheng used it once or twice, but later he felt that it was very fragrant and uncomfortable to use.Those aromatherapy bases are just the right size for this circle.So, something was burning in there.

A little breakthrough.

Du Yusheng turned around and wanted to show off to Li Yao.

Suddenly, the whole floor was plunged into darkness.
