The cause and effect of the case are generally clear, and there is now a lack of substantial evidence to prove whether the inference is correct.

Jiang Qingrui breathed a sigh of relief, everyone had been busy for so long and finally saw some progress, and her heart was a lot more relaxed.

Xu Shu walked beside her, and when she saw Jiang Qingrui's slightly excited spirit, a chuckle hung on the corner of her mouth.

"Take advantage of this momentum and try to take it down in one fell swoop!"

Jiang Qingrui said and shook her fist at Xu Shu, making a cheering gesture, full of energy to find evidence.

Now the most important clue is the bill, which has unfortunately been destroyed.

Xu Shu firmly believes that there will definitely be a place where the crime is secret, Jiang Qingrui also agrees with this point of view, the two discussed, and decided to go to Changfeng Company to take a look at it next.

It's a pity that Changfeng has been questioned inside and out, and there are no new clues.

Jiang Qingrui frowned and left the hall, thinking about where it might have been overlooked.

Just as the two were about to leave, she suddenly felt a poke in her arm.

Following Xu Shu's gaze, it was the security room at the entrance of Changfeng Company.

Unlike the previous visits, the doorman was replaced.

The two looked at each other and walked over in tacit understanding.

"Hello, police. There's something I want to ask you. ”

Xu Shu took out his documents and gave him a look.

The first time the doorman saw the two of them, his expression immediately became nervous.

"Okay, okay."

Xu Shu asked according to the process, but there was nothing new.

Just when Jiang Qingrui wanted to give up, the doorman patted his head.

"Officer I remembered, Ding Sibo gave me a letter before and asked me to help keep it. As soon as I was nervous just now, and it took a long time, I forgot about it. ”

With that, the doorman rummaged through a dozen thick piles of information.

He had taken a leave of absence before, and had not caught up with the previous investigations.

Jiang Qingrui's eyes were bright, and her intuition told her that this would be a very important clue.

Xu Shu took the envelope handed by the doorman, a thin layer, not thick.

When I opened, it was a piece of paper.

Jiang Qingrui and Xu Shu looked at each other, it was a company that asked Ding Sibo for an invoice for the purchase of steel!

When I was really sleepy, someone handed me a pillow, and an important clue suddenly appeared.

Xu Shu looked at it and made sure it was true, "It seems that Ding Sibo is afraid of any accidents in the future, so he specially kept an invoice." The path of the sky is endless, and it is just right to speed up the search for him. “

Jiang Qingrui nodded, agreeing with his statement, "It is this little cleverness that may allow him to be saved." ”

Xu Shu patted the invoice to Jiang Wu, "Check where this company is immediately, this is very likely to be a breakthrough." ”

"Team Xu, you two are so fast!"

Jiang Wu on the other end of the phone was surprised, and just as he wanted to talk about something else, he was grabbed by Xu Ying's ear.

"Ouch, you tap." He couldn't break free, and after grinning for a while, he shouted into the phone, "Don't worry, leave it to me, and make sure to find it out as quickly as possible." ”

The voice fell, and the phone was hung up immediately.

Jiang Qingrui heard how hard Xu Ying used through the phone, and subconsciously covered her ears, feeling that she was also in pain.

"Uncomfortable?"

Her movements attracted Xu Shu's concern.

"No, no."

Jiang Qingrui hurriedly shook her head, for fear that his next sentence would be to let him go home and rest.

The case has been followed up until now, and she wants to keep investigating until the truth is revealed and the murderer is found.

As he said, Jiang Wu quickly sent the company's information.

Xu Shu zoomed in on his phone, and Jiang Qingrui poked his head over.

"North City ......"

It's North City again.

It seems that the evidence of Ding Sibo's illegal joint theft has been confirmed.

Determining the address, the two went to the company in North City non-stop for further investigation.

It's late at night, and it's not a short journey.

Xu Shu stopped on the side of the road and came back with a large bag of bread in his hand.

"The shops are closed, and the convenience stores don't let you have hot food, so I just looked at it and picked something you should like to eat."

"Thank you so much, I'm just a little hungry."

Jiang Qingrui took it, opened it and gave Xu Shu a bag of bread, and took another one for herself.

She found that all Xu Shu took was strawberry flavor, and she thought that the desserts he brought to him some time ago were inseparable from strawberries.

Thinking about this like this, Jiang Qingrui's ears unconsciously burned.

Xu Shu was not interested in sweet things, and put it down after eating two bites.

Late-night business trips are commonplace for him, but this time is different, the co-pilot, who is often unmanned, has Jiang Qingrui.

Xu Shu couldn't say this feeling, his heart swelled, as if he was filled with something.

Oddly enough, he didn't resist this, and wanted to make it longer and slower.

The two of them have their own hearts, and time flies.

Jiang Qingrui was woken up, she rubbed her eyes to adapt to the light, and got out of the car with Xu Shu.

Xu Shu walked in front, his posture was tall, his expression was calm, and he couldn't see any traces of exhaustion at all.

Jiang Qingrui couldn't help but admire, she didn't know when she fell asleep.

"Police, come and ask about something, please bring your person in charge."

Xu Shu's words were concise, and the front desk immediately called after seeing the documents.

A short time later, a man appeared in a hurry around the corner.

"Hello, what's the matter? I'm the person in charge, you can just ask me about anything. ”

As soon as the people came up, they shook hands with Xu Shu and Jiang Qingrui respectively, with a sincere attitude.

Jiang Qingrui noticed that his hair and neckline were messy, and it seemed that he rushed over immediately after receiving the call. His demeanor is neither humble nor arrogant, but his eyes are wandering, and his voice trembles unconsciously when he speaks.

Xu Shu took out a photo of Ding Sibo, "Do you have an impression of this person?" ”

The person in charge saw the photo, his pupils contracted, and he hesitated for a few seconds and said, "I've seen it." ”

This time, the questioning went unusually well, and the person in charge told the truth as it was.

"Ding Sibo bought a batch of steel for the company, and our two processes are all formal channels."

The person in charge glanced at Xu Shu, whose expression was getting more and more serious, licked his chapped lips and said, "Brother policeman, I can guarantee that there is no mistake on my side at all, and he is ...... I don't know. ”

"I worked with him once, and after I was done, this kid disappeared, and I didn't know him well, and I didn't usually cross paths."

The person in charge threw himself away, and the focus of Xu Shu was not here.

"Your company will issue invoices after each project, can you find the invoice for the cooperation with Ding Sibo?"

Hearing this, the person in charge didn't speak for a while, and hesitated for a long time, "He didn't give me a formal invoice." ”

"But," he said, "some time ago, he contacted me and said that he could handle as much steel as he wanted in the future." ”

went around and went back to Section Chief Zhou.

Xu Shu and Jiang Qingrui decided to investigate secretly, and the handwriting of Section Chief Zhou and the people close to him was taken for identification one by one.

They have a guess, and the last point may be the key to solving the mystery.
