Sometimes, Bai Song can go to sea like a dragon, and he will win with one blow, and in the face of some cases, he can quickly rush forward and will not stop for a moment.

But there are also times when he can encounter big things and be calm, especially after what happened last time.

As an open class, Bai Song listened to it from the beginning to the end, without showing any impatience at all, and invited Ding Jianguo to have a meal with Wang Huadong after class.

The reason why I want to accompany him is because Wang Huadong is afraid of embarrassment when he invites a guest, and even if the girl does not agree to such an invitation, it is not embarrassing. They are all "teaching assistants", working meals...

As for Ding Jianguo, he agreed to the two of them, but they ate in the cafeteria.

It's a bit embarrassing, neither of them has a meal card, and the treat is...

......

However, this is a good start, in Wang Huadong's words, this has found a reason to invite the young lady to dinner next time.

After separating, Bai Song got into Wang Huadong's car, and as soon as he got in the car, he immediately took out his mobile phone and dialed the phone number of the Qin detachment.

"Detachment Qin, I have an idea that I want to verify. Bai Song said bluntly.

"Wait a minute. "The Qin detachment was holding a meeting in the city, and left the venue directly.

After almost twenty seconds, the Qin detachment said, "You say." ”

"I want to do a test on the money about Tian Huan that is being seized now. ”

"Testing, how to testing?" the Qin detachment was a little puzzled, "We have done an inspection of this money, and there is nothing contraband." ”

"Have you checked every single one?" asked Bai Song.

"That's definitely not the case, but Team 4 also found professional drug detection dogs from Team 6. "The Qin detachment didn't understand what Bai Song wanted to say.

Seeing that Bai Song didn't speak, the Qin detachment added: "If you have any ideas, just say it." ”

"Okay", Bai Song was not afraid of being abrupt, and said directly: "This stack of money, especially the bottom stack, I want to test whether the paper contains highly toxic substances." ”

"Is there a specific poison conjecture?" Qin Detachment said calmly, as a forensic doctor, his understanding of this aspect is far beyond that of Bai Song, and he naturally knows the benefits of narrowing the detection surface.

"Botulinum toxin. Bai Song said his conjecture: "But I don't have a clue about the specific plant type." ”

"Botox toxin?" Qin Detachment pondered, "Okay, I see." I will immediately arrange for someone to be sent to the Criminal Division. ”

"Thank you Qin detachment, Wang Huadong and I also rushed over. Bai Song hung up the phone.

...

Turning off the phone, Wang Huadong immediately turned the head of the car, and without asking, he set foot on the road to the criminal department.

"Why is money poisonous?" asked Wang Huadong.

"I'm not sure, just guessing. Bai Song said truthfully.

"You've never made a nonsensical guess, don't sell it, tell me. As a member of the project, Wang Huadong is eager to know more.

"I've been planning a perfect crime about Tian Huan. Bai Song looked out the car window: "How can you let Tian Huan die because of himself." ”

"So?" Wang Huadong still didn't understand.

"Have you seen the video of Tian Huan's interrogation?" Bai Song asked.

"I've seen it several times, and I've been involved in interrogations, and I haven't found any problems. Wang Huadong shook his head, and he was a little distracted while driving.

"Do you remember that when he was flipping through the transcripts, he had a habit?" Bai Song asked.

"Habit, what habits can you have when you turn over the transcript?" Wang Huadong recalled desperately, and said uncertainly, "He prefers to dip his saliva?"

"Yes. Bai Song said: "He is from the south, and he stays in the north, so he will feel a little dry." I don't know what the reason is, every time he turns the paper, he likes to dip his saliva, and this habit is stronger than that of ordinary people. I compared it with Lei Chaoyang last time, and it's even more so, you must know that Lei Chaoyang is also a southerner. ”

Wang Huadong is even more confused, what does it matter?

"Do you think that if I die in the car accident in April and Tian Huan's mission is completed, what is his plan?" Bai Song did not answer directly.

"Run, let's go abroad. Wang Huadong blurted out.

"Of course this is true, but in such a case, is it safe to run away?" Bai Song said: "ZZ criminals cannot be extradited by many countries, but if he kills me, he will have no one to protect him wherever he goes, and sooner or later he will be extradited back." ”

"So", Bai Song said with certainty: "Tian Huan himself actually doesn't know, if he successfully completes the task, then he will definitely not survive, and the people behind him will not even let go of the driver, how can they let him go?" Therefore, Tian Huan will definitely die, and the cause of his death is related to the existing clues, but it is difficult to guess.

According to common sense, if Tian Huan doesn't say anything about the money we seized, we won't be able to find it.

However, after losing the case, Tian Huan took out the money to fight the matter on his own.

That is, the money is part of Plan B.

However, if he succeeds, what will he do with the money when he executes Plan A?

He must have known that he couldn't carry so much cash on a plane, but would he really give up so much money? Of course not.

At this time, Tian Huan definitely wanted to take this money privately, and he had no relatives in Tianhua City, and it was impossible for him to dare to go to the bank to exchange or deposit this money at this time, so he had only one choice, which was to hide in a place that no one knew. In the future, if he still has the opportunity to return to China, or if his family and friends come to Tianhua City, he can also withdraw the money.

And Tian Huan likes money so much, he must count it, after all, there is such a thing as running away, and the ticket has not been bought, there is no need to race against time, he will definitely count the money with his own hands.

There may have been millions of dollars in the past, but the bottom ones were not allowed to be spent from the beginning, and they were part of Plan B.

Therefore, in the bottom few stacks of money, if there are some highly toxic ingredients, Tian Huan, who likes to dip in spit and count money, will die.

Moreover, this poison time is not instantaneous, if it is botulinum toxin, it usually takes a few hours.

He counted the money, hid it, and then left, and then died of poison.

When he died, we couldn't even find the source of the money and the toxins, because he hid it himself.

When the time comes, it will be really difficult to solve the case of his death. ”

"Moldy money, will he still dip it in saliva?" Wang Huadong was a little confused when he heard it, this can be connected.

"The moldy money is evidence for us, and we will definitely use gloves until the case is over, and this money will also be sent to the People's Bank for replacement. But, for him, it's money. Bai Song pursed his lips: "A rich person like you doesn't understand, in fact, if 100 yuan falls into the dung pit, many people will find a way to get it out, let alone so much money?"
