Jiang Qingrui understood, "No wonder that boss has such a bad attitude towards us, I guess he thinks we are the ones who investigate exhaust emissions." ”

Xu Shu informed the police officers to return to the bureau for a meeting.

With all the information, it is most likely that this public bath is currently the most likely one.

"But if you just come here to take a bath, it shouldn't lead to death, there are so many people who go."

Jiang Wu was puzzled.

Xu Ying scolded him when he heard this, "Since Jiang Jiang said so, he must have his own reasoning, and you don't understand, talk less and listen more." ”

"Jiang Jiang, what do you say is going on?"

Everyone looked at Jiang Qingrui.

Jiang Qingrui clenched the pen in her hand, and she said, "This bath emits carbon monoxide in violation of regulations, and it is likely that it will enter the household's home when the concentration is too high, and whether it is Zhang Xia, Qian Yuan, or Chen Yang, they were all poisoned at home when there were the least people. ”

"But how do we prove it now?"

Jiang Wu was a little anxious, "We don't have any evidence to arrest them now." ”

"Rest easy."

After Jiang Qingrui groaned, she looked at Xu Shu, "I think that if you want to prove this, you can only evacuate the residents in the community and do an experiment." ”

"No, it's too exciting, and it's unrealistic, and it's easy to affect the normal life of residents!"

Jiang Wu felt that it would not work.

"But if we don't, we won't be able to prove that the death of the dead is related to the public baths, and maybe more people will die."

Qiao Linlin agreed with Jiang Qingrui's proposal even more.

But she also knows how difficult it is to get the proposal through.

The pressure instantly fell on Xu Shu.

Xu Shu lowered his eyes, thought briefly for a moment, and said categorically: "I agree with Forensic Doctor Jiang's proposal. ”

"I'll go talk to the director."

To everyone's surprise, when Xu Shu said this idea, he was opposed by the Ye Bureau.

"Nope."

Ye Ju, who usually laughs, is very serious, "You guys are just messing around, how many people are there in the community, let all the residents quit, it's up to you to think of it!" ”

"This plan doesn't work, you can find another way!"

"Leaf Bureau!"

Jiang Qingrui was a little anxious, "If you don't do this, there will only be more people ......."

Ye Ju didn't let her continue.

"That's true, but if it's not for this reason, who will bear the consequences?"

Xu Shu clenched his fists, "Ye Ju, I'll take it!" ”

His voice was heavy, his eyes were sharp, and he stood straight.

Ye Ju was laughed angrily, "You take it, aren't you really afraid of carrying the punishment?" ”

"In order to solve the case, for the sake of more potential victims, I am willing to bear the consequences, there is nothing to say, I believe in Jiang Forensics!"

Xu Shu's eyes did not squint, and every word was extremely clear, "She is not only a forensic doctor, but also my most powerful assistant, I believe that she must have no other way to make such a decision, I believe her!" ”

Jiang Qingrui's heart was shocked, she didn't expect Xu Shu to trust her so much, and she felt hot for a while, and she was a little moved.

"Ye Bureau, if the result is different from what we guessed, I am also willing to carry the punishment and bear the consequences!"

Jiang Qingrui and Xu Shu both expressed their positions, and they were there, and the two of them looked at Ye Ju with straight eyes.

Ye Ju was holding a teacup, and the taste of Longjing tea sent by his friend before the rain was overflowing, but he had no intention of tasting it.

"Since that's all said, let's go."

Dullness swept through the room, and Ye Ju suddenly said.

Xu Shu and Jiang Qingrui were pleasantly surprised.

"Still."

Ye Ju's words changed, "If you can't get any results, see how I clean you up!" ”

With the support of the Ye Bureau, this matter is much easier, the police officers are all mobilized, Jiang Qingrui, as the main operator of this experiment, in order to prevent the sample from changing and causing errors in the results, she specially chose the same time period as when the crime occurred.

The police cordoned off the public baths, burning coal at specific times and emitting gases into the sewers, as usual.

Jiang Qingrui began the carbon monoxide concentration test.

Before the time came, Jiang Qingrui and the others were guarding outside, and Xu Shu handed Jiang Qingrui a bottle of water and sat beside her.

"Drink some water, don't be so nervous."

"You're not nervous?"

Jiang Qingrui turned around and asked him, "If I don't succeed this time, you will have to bear a big punishment." ”

"I said it, I believe you."

Xu Shu repeated again, "Moreover, if it is not successful, the residents will eliminate a potential safety hazard, whether it is to solve the case or everyone's safety, it is a good thing, and a punishment is worth it." ”

"What's more......" Xu Shu hooked his lips, "I believe in your professional ability." ”

"Hmm."

Jiang Qingrui was in a much better mood, drank some water, her thoughts became clearer, and the tension just now suddenly disappeared, "Okay, I'll try not to let you and me carry the punishment." ”

"Touch it."

Jiang Qingrui said, the mineral water bottle in her hand touched the bottle in Xu Shu's hand, "I wish us a victory!" ”

Time passed little by little, and everything was ready.

When it was time to start the experiment, after making sure that there were no interference factors and everything was in place, Jiang Qingrui held the walkie-talkie in her hand and stared at the data transmitted through the device on the screen.

"Let's go!"

She spat out two words, and the officers in the bath began to operate.

Everyone held their breath and looked at the line of carbon monoxide on the screen, rising from zero.

Over time, the concentration of carbon monoxide in the room begins to increase.

Eventually, the value stopped.

The carbon monoxide concentration in Chen Yang's home stopped at 0.23, and the carbon monoxide concentration in Zhang Xia and Qian Yuan's home stopped at 0.3.

"Is this done?"

The atmosphere was suddenly silent, and Jiang Wu asked Qiao Linlin in hindsight.

No one answered.

Jiang Qingrui's eyes were glued to the numbers above, and after reaching this peak, the carbon monoxide concentration in the room never changed again.

"The experiment failed."

Jiang Qingrui's tone was heavy, and her voice was a little hoarse, and the entire police force dispatched a large number of police forces for this experiment.

And in order to prepare, she was busy with this all day, Jiang Qingrui was full of confidence, and she didn't expect this result at all.

"How did it fail?"

Xu Ying didn't understand, and pointed to the number above, "Isn't this carbon monoxide?" ”

"But it's not enough."

Jo Linlin explained in a low voice, "The lethal concentration of carbon monoxide is above 0.32, and this amount does not kill people. ”

The crowd was silent.

"I'm sorry."

Jiang Qingrui showed a look of guilt on her face, lowered her head, and apologized to Xu Shu and everyone with some apologies.

"It's a whole day of delay."

Jiang Qingrui announced the results of the experiment with difficulty, "This experiment failed. ”

With that, she walked out of the room.

Not long after, Xu Shu found her on the steps outside.
