On the way back, Bai Song received a call from Song Suo again, asking Bai Song to have dinner tomorrow night.

Bai Song is the leader of the fourth group, Li Yunfeng is the first group, Song is in the second group, and Li will be on duty tomorrow, so the fourth group and the second group will have time tomorrow night.

Of course, Bai Song was not invited to eat alone, but all the four groups were invited to eat.

As the number one leader in the institute, the Song Institute has a total of four groups and a case-handling team, and the cohesion of these people is directly related to the combat effectiveness of the whole firm.

A police station is not the same as a police station.

The directors of the Jiuheqiao Police Station and the Sanmu Street Police Station seem to be at the same level, but there is still a gap in status. The Sanmu Street Police Station is one of the best police stations in Jiuhe District, and it may be directly promoted to the head of a certain detachment in the future, so after Song was transferred to the top leader, he was full of enthusiasm and looked forward to good results.

The other three groups of Song have all been invited, and now there are only four groups left.

Generally, subordinates make an appointment with the leader, at least three days in advance.

The leader makes an appointment with his subordinates, depending on the mood.

Bai Song agreed, and then called Ren Xu, asking everyone not to arrange other private matters tomorrow night, and go to the restaurant that Song said was good for dinner.

Even if you simply eat a stir-fried dish, it won't cost much, but the leader's heart must not be ignored.

"By the way, I have to tell you", Bai Song thought for a while, "Before you go to dinner tomorrow night, you find a place to eat three hamburgers and a pad." ”

"Huh?" Ren Xu didn't understand what Bai Song meant. How can you have a big meal and have to eat a hamburger first?

"Ah, what? The leader has a treat, and it's not like a few of us sit down to eat together, the leader orders 12 dishes, you eat 8 in one go, and the leader has to add a few dishes for you, do you think it's appropriate?" Bai Song knew Ren Xu too well: "You have to remember my words, and taste them carefully." ”

"I see what you mean. ”

Ren Xu had palpitations after hanging up the phone, but fortunately Bai Song reminded him!

Otherwise, after tomorrow, although it is impossible for the leaders to wear small shoes for him, it is also very embarrassing...

The police station is different from the big organs, and the leaders like Ren Xu like him very much.

It's just that if you can leave a good impression on the leader, then you will always have a brighter future in the future.

...

Back in Tianhua City, it was already more than seven o'clock in the evening, and Bai Song went to find Liu Shuyuan for the first time.

"What called me, is there a clue to Zheng Yanwu's murder that I said?" Bai Song asked hurriedly.

"Do you treat me as an immortal?" Liu Shuyuan glanced at him: "However, there is something related. ”

"You say. Bai Song lowered his posture suddenly, and listened attentively.

"I don't have any friends from the public security in Shonan Province, but I have a friend who is in the government, and I sent him a document, and he helped me find someone from the Taxation and Market Supervision Administration, and passed on all the materials of Zheng Yanwu's previous printing and dyeing factory. Liu Shuyuan took out a large stack: "It's too much, I looked at it for a while, and I couldn't understand these accounts." ”

"Okay, I'll see. Bai Song took the box in Liu Shuyuan's hand, it was quite heavy.

Bai Song looked at the scrolls there, and Liu Shuyuan was a little impressed.

The stuff of these companies is simply incomprehensible to the layman. An insider can judge many, many things from a single ledger, while a layman only knows 1234567890.

But Bai Song actually taught himself the knowledge of certified public accountants, and he usually learns this kind of thing. He didn't have time to prepare for the exams right now, otherwise he would have hoped to pass a few of them.

It's still okay to look at these materials.

Bai Song was there to read the materials, and the tome books he had taken from Shangjing City were temporarily placed on the table.

"I can't read those accounts, I'm okay with his books after all, right?" Liu Shuyuan thought secretly, and began to look through the books that Bai Song had brought over.

Flipped through a book... Flipped through another book...

Again...

Liu Shuyuan began to doubt life.

Are these all books that the police can read? Are you sure this isn't the book that a doctor should read? What the hell!

And there are several, all in English!

There is another one, is this in German???

The law of White Pine is already at this level?

Liu Shuyuan has been fighting hard recently, and now looking at Bai Song's back, he is completely depressed.

I can't catch up with this gap.

...

Bai Song watched for more than an hour, during which he wrote down a lot of things in his notebook with a pen, and calculated a lot with a mobile phone calculator, sometimes frowning, sometimes suddenly.

"Is there a problem?" Liu Shuyuan watched Bai Song close the booked case file, poured Bai Song a cup of tea, and handed it over.

Bai Song was stunned for a moment, he really hadn't seen Liu Shuyuan pour tea.

"Don't drink tea?" Liu Shuyuan's voice was not loud: "Or, pour you a glass of ice and happiness?"

"No, no", Bai Song took the teacup and pointed to what he had written: "There is a problem with this company." ”

"Just now, when you didn't come, I looked for the accountant, and the accountant said that there was nothing wrong with the books. ”

"It's fine on paper. Bai Song said: "But there are problems with raw materials and output. ”

"What do you mean?" Liu Shuyuan leaned closer and saw a large number of chemical equations he didn't know, and he was a little dizzy.

"Their company has a lot of printing and dyeing products, but most of the products are alkaline and cationic dyes, because there are many types of production, and many raw materials are cross-used, there is no way to calculate", Bai Song pointed to an equation in the book: "They began to produce a reactive dye a few years ago, to be exact, it is called KN type diazo reactive blue dye, which is a kind of vinyl sulfone reactive dye." And to produce this reactive dye, a chemical called p-nitroaninose is required. ”

"So what?" Liu Shuyuan found that he could only understand the word "chemical".

Looking at Liu Shuyuan's appearance, Bai Song suddenly wanted to tease him: "It's very simple to produce this blue dye. Mix p-nitrobenzine with water and concentrated hydrochloric acid, heat and dissolve, quench on ice after dissolving, and then add sodium nitrite aqueous solution at low temperature. In diazotization reactions..."

Bai Song talked about the steps in general, and he talked about it for about fifteen minutes.

"What do you want to tell me?" Liu Shuyuan rubbed his temples.

"Actually, what I just said is useless. We just need to know that because the process is very stable, it stands to reason that the ratio of p-nitroaniline to blue dye purchased should be fixed. Bai Song said: "Considering that there will be raw material hoarding and other situations, there is no way to give an accurate assessment, but if you roughly estimate it on a monthly basis, it can be clearly seen that in recent years, the production of dyes has exceeded what raw materials can provide, which is not explained by process improvement." ”

"It's useless for you to say a fart..."Liu Shuyuan almost complained, but he still held back this sentence.

Liu Shuyuan endured it and said, "So you just tell me that these raw materials may have smuggled raw materials, isn't it?"

"Isn't it easy to understand if I'm going to tell you more detailed?" Bai Song didn't feel anything, and continued: "This data is too little, we need more data." ”
