Liu Shuyuan and Wang Huadong looked at Yang Ruiri, Bai Song went out to make a few calls, and then went back to the house.

There is no jurisdiction over this matter.

It's not that the Jiuhe Branch doesn't have jurisdiction, it's that the Public Security Bureau doesn't have jurisdiction.

How can there be so many absolute "commercial" spies?

Someone from the city bureau will come directly to the city, and the case will be under the jurisdiction of a security department.

"Why are you so struggling?" Wang Liang asked curiously, "In the end, this matter is so solved?"

"Aren't you going to have a treat at noon? I'll want to eat river crabs in a moment. Bai Song ignored Wang Liang's stubble.

"Ah, it's not spring yet, where are I going to get river crabs for you?" Wang Liang asked.

"Breeding crabs still depends on the season? You haven't eaten them during the New Year? Don't talk about it, do you want river crabs?"

"Please, please, please. ”

...

Wang Liang still didn't understand, Liu Shuyuan generally understood something.

The next thing is that the city bureau comes over and then makes a handover with the relevant departments.

...

"What's this called?" Wang Liang was a little unhappy and sighed: "This is really incomprehensible, and it is different from the Xingang Branch." ”

"You know, it's okay, but it's okay, this matter involves other units, and in the end, if you investigate a big case, you will also have merit. Liu Shuyuan seemed to have a deeper understanding of these things: "Then the city bureau is here, let's just leave." ”

Bai Song didn't say much, and called Master Tang to a room alone.

"Professor Tang, let me ask you a question, and you think about it carefully. Bai Song said.

"You say. Professor Tang was not in a good mood, but he still replied very seriously.

"I look at you, and I see that the problem comes from a very small detail, and it is a fleeting thing. Bai Song pondered his tone: "Can you tell me why?"

This can't be doubted by Bai Song, this kind of thing is not necessarily the first time.

Professor Tang, the first does not have the vigilance of professionals such as the police, and the second age is really not young, even Bai Song does not pay attention to this kind of detail, how did Professor Tang find out?

Was this the case before, or was Professor Tang actually suspicious of the students?

Professor Tang was silent.

"Professor Tang, I'm not afraid that you have subjective thoughts, you can say anything, and I am not a case officer in the real sense. Bai Song encouraged.

"Alas," Professor Tang said, "Actually, it's nothing else, I sometimes always feel that I may be really old, and I am prone to cranky thoughts. What you said is actually true, I did find out about this situation, but every time it was a flash, and I didn't have any special ideas, let alone be sure about it. It was because of my somewhat neurotic concern that I found out about this problem today. And I'm not sure, I can't report it, so I'll call you over to confirm. ”

"Well, that makes sense. Don't think about it, I think your thinking and discovery are very reasonable. Bai Song expressed his approval: "You also saw Yang Ruiri's situation today, do you think he is lying?"

"Nope. Professor Tang sighed: "He's a good boy, to be honest, I don't really blame him." If I can help with his niece's illness, I will still help now. ”

"Well", Bai Song tried not to think about so many emotional factors: "Then do you think that he said that it was the first time, do you believe it?"

After Yang Ruiri admitted the incident himself, he said that this was his first time.

Everyone didn't believe it, but Bai Song just talked to Yang Ruiri again, and Bai Song believed it. 16

It's not just because Yang Ruiri's niece hasn't gone abroad today, but more importantly, because of Yang Ruiri's behavior in watching the surveillance.

If there have been many similar behaviors in the past, don't wait until the near future to start looking for a blind spot in the surveillance, right?

Moreover, Yang Ruiri also confessed to the theft of these things.

The one who stole was another person, Yang Ruiri's sister.

This kind of thing can't be done by outsiders, and they don't have the courage to do it, Yang Ruiri doesn't have time to steal, his sister does.

As for the blind spots of monitoring, including various operation modes, Yang Ruiri repeated it to his sister N times after understanding enough, and then he had today's action.

Moreover, because the transaction of this material must be made by Yang Ruiri himself, it is still in his sister's place.

These don't need to be considered by Bai Song, including the arrest of his sister and the arrest of those who buy trade secrets, all of which are responsible for the relevant departments.

However, having said all this, what Bai Song is most concerned about is that if it is really the first time that this thing has been stolen as Yang Ruiri said, then what is the matter with Professor Tang's previous discovery?

Is it really a fantasy?

Bai Song and Professor Tang have known each other for a short time, this person is very free and easy, and he is not a person who thinks crankily with a little achievement, so if Professor Tang can doubt this matter, then this matter will not be simple.

After thinking about it for a long time, I didn't get anything, and finally waited for people from the city to come.

Bai Song met the leader of the city bureau, this person Bai Song has also seen, although he is not familiar with it, but he is always his own person.

The term "own people" is relatively relative, at least for people from other units.

These few people from other units also came with two leaders.

Although this unit is special, it is not a three-headed and six-armed unit, if it is really compared to the ability to investigate and handle cases, it is really not necessarily better than Bai Song, there is a specialization in the art industry, plus some mystery, that's all.

The process of handing over the work made Bai Song very uncomfortable, and he didn't have any legal documents, so he just wanted to leave the case.

If it weren't for the presence of the city bureau, Bai Song would feel that this matter was a little incomprehensible...

"Can anyone tell me all this from beginning to end?" asked Captain Peng, who was in charge of the unit.

The people from the city bureau shook their heads, and everyone looked at Bai Song.

They all work in one place, and there is cooperation between the city bureau and this side, and many people are friends in their lives, so they are polite to speak.

From beginning to end, from the discovery of the case to the final analysis, Bai Song quickly recounted, and several people nodded frequently.

"Well, this white captain has a solid business ability. Captain Peng smiled: "Then please avoid it, the work needs." ”

Everyone walked out for dozens of meters, and Bai Song saw that he was about to walk to the staircase, but finally stopped.

"What's wrong with the white team?" asked the leader of the city bureau.

"I also want to have a few words to say to Captain Peng. Bai Song finally made a decision.

"En?" The leader of the city bureau looked at Bai Song: "Okay, you go, we'll wait for you." ”

Bai Song nodded, no nonsense, went directly to Captain Peng, and chatted alone for about ten minutes.

In the end, Bai Song gave a conclusion: "Captain Peng, here, you must pay special attention to one person. ”

"Who?" said Captain Peng thoughtfully.

"Ding Jianguo. ”
