Controlled experiment

Coming out of Gu Qingyu's house, Du Yusheng was holding a deep breath in his chest.

Along the way, Du Yusheng's face was dark, he was unhappy, and Xiaobai could see it.Like Gu Qingyu, there are not a few people who think that wealthy businessmen should contribute money free of charge. There are many around them, and there are many more on the Internet. However, Gu Qingyu also added that he still owes money without repayment, which is contemptuous .

Du Yusheng walked downstairs to his house and looked up.

I haven't finished moving my house yet, so I guess there is still an hour left, and Du Yusheng has to put it back, so it will take a morning anyway.

Du Yusheng glanced at Xiaobai.

"What do you think about Gu Qingyu?"

"That's right. I've just discovered that when Gu Qingyu was talking to me, his pajama pants were almost torn. , why is it so coincidental, just a pair of shoes, just wipe the uppers, even the soles of the shoes. And seeing that Gu Qingyu doesn't look like a person who pays attention to hygiene, I think he must be doing something with those shoes gone."

Xiaobai put his hips on his hips, combing himself while talking.

"You still remember that night, we didn't find a single footprint in Chen Xin's ward." Du Yusheng said: "If the murderer is this Gu Qingyu, then he must have been worried after cleaning up the footprints at the scene, and even with Go home and clean the soles of your shoes.”

Logical, Xiaobai nodded.

"But there is one more problem." Xiaobai frowned and said, "When we were leaving, he asked us what happened to Chen Xin. From the looks of it, he really didn't know that Chen Xin was dead."

"Yes, that's what I can't figure out." Du Yusheng yawned and said, "Don't think about it yet, you go and call out the surveillance at the door of Gu Qingyu's house. If he came out by car, contact the traffic department to find out. Its driving route to see if it went to the hospital. The hospital should also be monitored."

Xiaobai nodded.

"Also." Du Yusheng asked: "Have you checked Chen Xin's other circles? Is there anyone suspicious besides Gu Qingyu? Didn't his father say that Chen Xin owed the factory money? Are there any workers who are owed wages?" If it’s impossible, check it out.”

Xiaobai rolled his eyes secretly, thinking how much work this is.

You can just open your mouth.

Scratching his nose, Xiaobai added: "Brother Yu, I see enough. The workers don't want Chen Xin to die. Once he dies, they won't be able to get the money. So far, the most motivated crime is the one upstairs. This Gu Qingyu, once Chen Xin dies, there is no need to pay back the money."

Du Yusheng looked back at Xiaobai and left a sentence.

"That also needs to be investigated."

Although it was a normal process, Xiaobai still raised his middle finger at Du Yusheng's back.

Du Yusheng felt much more comfortable after confessing the errands in his heart.

To be honest, he hoped that the murderer was this Gu Qingyu, because if the murderer was someone who had nothing to do with the deceased Chen Xin, the case would be difficult to handle. .Besides, so far, it seems that the murderer is very thoughtful, leaving no trace at the scene, except for the surveillance video, and Qin Yan has not sent the cause of death yet, so he also encountered a problem.

When Du Yusheng got out of the elevator, he immediately saw Li Yao standing at the door and yawning.

It may be that seeing Du Yusheng gone, no one is worried about moving, he is leaning on the door panel in his pajamas and staring at these movers.He was woken up very early, his face was full of tiredness, but his eyes never left the movements of the masters, and Du Yusheng's heart suddenly warmed up when he saw it.

If he could, he really hoped to go up and give him this and that.

But as we get closer in the future, this and that will happen sooner or later, Du Yusheng was thinking about it in his mind, and his heart beat faster.

"Why are you still standing here?" Du Yusheng walked over hurriedly, and said, "It's cold outside, my things are worthless, and the moving company will pay if I lose them."

Li Yao tilted his head and smiled, "It's okay, I'll rest today too."

"If you take a break, you have to take a good rest."

Du Yusheng opened the door of Li Yao's house and pushed him in.

The move on his side has also come to an end, all the furniture has been moved in, and Du Yusheng is left to put it away by himself.

The leader took the settlement slip in his hand and confronted Du Yusheng with the furniture and the amount. Du Yusheng didn't have the heart to go over it one by one, so he signed his name on the bottom of the settlement slip, and transferred the money with Alipay in his hand.

Before leaving, I brought a box of mineral water to the masters who moved.

After finishing these things, Du Yusheng wiped his mottled shoes, turned around and saw Li Yao still standing there, looking at him with a smile on his face with the door open.

Du Yusheng cursed in his heart, his face turned red, and he said to himself that this progress is progressing by leaps and bounds.

"Have you had breakfast?" Li Yao asked him.

Du Yusheng shook his head dully.

Li Yao stretched out his hand to greet him, and said, "I didn't happen to eat either, let's eat some together."

Du Yusheng still maintained his shoeshine action, so surprised that he didn't seem to be able to react.The tone of Li Yao's inviter is very strange, it doesn't feel like he is inviting you to dinner again, just like saying 'hello' to you, without any emotion.If it weren't for Li Yao's smiling eyes, Du Yusheng really felt that his heart was not sincere and his purpose was not pure.

No matter what, Du Yusheng still followed along.

In fact, Li Yao seldom cooks. The kitchen utensils are [-]% new. His cooking skills can be described as earth-shattering. Anyone who has eaten it feels soul-stirring, so Li Yao can at best make a semi-finished product, cook a noodle, and the next one Quick-frozen dumplings are just a few of them.

It is the same today.

The corners of Du Yusheng's mouth twitched slightly as he looked at the things on the dining table, and thought to himself that Li Yao might really have a wrong heart and an impure purpose.

The toast is heated in a bread machine, the poached eggs are molded into a microwave oven, the soy milk and milk are heated and instant, and the only thing that has been thought about is that the ham sausage is freshly cut by Li Yao.Du Yusheng couldn't sit still looking at each piece of ham sausage up to one centimeter thick.

He snatched the kitchen knife from Li Yao's hand, rolled up his sleeves and sighed.

"You know how to hold a scalpel in this hand, don't you?"

Du Yusheng took the cutting board under the sink and washed it. He glanced at Li Yao, who obviously didn't know what he was going to do.

"You, uncle, sit down properly." Du Yusheng added, "Wait to eat, I will show you a hand."

There was half a bowl of leftover rice in Li Yao's refrigerator. Du Yusheng sniffed it under his nose to confirm that there was no corruption. There was still a tomato in his refrigerator. Du Yusheng thought about it and took out the tomato.

Ham sausage, eggs, rice.

Enough to cook a meal.

There were too few ingredients in his house, so Du Yusheng made egg drop soup with the tomatoes.

In less than 15 minutes, rice and soup were served steaming.

Li Yao blinked and looked at Du Yusheng with disbelief on his face.Knowing each other for so long, this is the first time that Du Yusheng saw such an expression on Li Yao's face, like a wicked teenager.

"I haven't eaten anything good just by looking at it." Du Yusheng took a bowl, glanced at his watch by the way, and said, "It's just right for breakfast at this hour."

Du Yusheng was good at cooking. Li Yao took a bite and nodded. Du Yusheng touched his chin with a smile, his face was full of complacency.

Li Yao ate slowly, which was the opposite of Du Yusheng's gobbling. Du Yusheng chewed his rice, and couldn't help looking at Li Yao's face. He felt that the feeling of two people eating at the table was very good.Like a family.Since Mr. Du had an accident, Du Yusheng seldom came home. He has been hiding this from Mrs. Du, telling her that Mrs. Du went to the Middle East to open up markets. The wife also slowly realized what happened. The two of them were separated by a layer of window paper, and neither of them said anything.Du Yusheng was afraid that every time he went home to face Mrs. Du's eyes, she was obviously extremely sad and pretended to be indifferent and didn't know anything.

Du Yusheng felt ashamed and didn't dare to look her in the eyes.

Over time, he seldom came home.

But today, after eating an ordinary meal, Du Yusheng felt like he had been away from home for a long time. Maybe it was because the only son was alone for too long, and Du Yusheng felt a little nostalgic.

"Is it delicious?"

Li Yao nodded.

Du Yusheng lowered his head and smiled contentedly.

Halfway through the meal, Xiaobai sent a WeChat message. Du Yusheng looked at the message and snapped his fingers.

Li Yao said: "What's the matter, I'm so happy."

Du Yusheng closed his phone and said with a smile: "Didn't I go to find that Gu Qingyu just now? This grandson doesn't admit anything, saying that he has never gone out at home. Guess what, Xiaobai saw it in the surveillance video. Gu Qingyu drove out around ten o'clock in the evening, and his car was parked in the underground parking lot of Huandao Hospital. It was probably before eleven o'clock, and Chen Xin was killed between eleven and twelve o'clock, and Gu Qingyu's height and body are very similar to the person in the surveillance video at Chen Xin's door."

Li Yao ate the last few grains of rice in the bowl and pushed the bowl aside.

"So you think he killed Chen Xin?"

Du Yusheng nodded and said, "It's very possible."

Li Yao suddenly smiled, took a piece of paper and a pen from the side, and with a few strokes, he simply drew the general situation of Chen Xin's ward.

Reverse, and put the paper facing Du Yusheng.

Li Yao closed the pen cap and said, "I think exactly the opposite of what you think. I don't think Gu Qingyu is the murderer who killed Chen Xin."

Take a sip of the warm water ahead.

Li Yao finished the rest.

"When Gu Qingyu entered the ward, Chen Xin should have died."
