"It's okay Team Shao, I can understand you. Now let's go, go back to the hotel, and wait for the news about Zhang Hua from the police station. ”

As we passed by their kitchen, I noticed a sink full of water in their kitchen.

Suddenly, a flash of inspiration crossed my mind. The puzzle piece that had never appeared appeared suddenly appeared in my mind.

I rushed out and saw Wang Yun who was still washing in the yard, and asked her:

"Xiaoyun, let me ask you something."

Wang Yun raised his head in confusion, his mouth was still full of white foam of toothpaste. She spat out a puddle of foam in her mouth and looked at me in a daze.

"Do you use pump water or tap water?" I looked at her excitedly.

"Tap water. Our family used to use a well, but now we don't use it. Every house has running water, and who still uses that. ”

"When I first came out, I saw that the sink in your kitchen was full...... This is? ”

"Oh, you said that, our house has been without water for the past two days. It seems that it is not only our house, I heard that it is raining heavily in the upstream city, so the tap water in our village should have been shut down recently. ”

"When did the water outage start?" I babbled on and on, trying to get to the bottom of the question.

Because I feel that at this point I am about to penetrate the shell and touch the core of this matter.

"A few days ago, it should have been ......"

"The days your uncle died." I said confidently.

Wang Yun looked a little surprised, she tilted her head and thought for a while, then nodded, and said approvingly:

"Well, you're right, it should be those days or two."

"Okay, I got it. Xiaoyun, you and your mother should stop eating the water in your tank, pour it all out, buy mineral water, or borrow it from a neighbor. In addition, if your mother's stomach pain is not completely cured after she comes back, let her take a car to the city hospital. ”

I'll be quick to say. Then he ran into Li Zhenbo's room, took out his book, and took a picture of the pages of the contents of the "suicide note" that we cracked with his mobile phone. Then I went to the kitchen and took some water from the sink to take back to our police station for testing.

Behind him, Wang Yun's footsteps came.

"Officer, you...... I don't understand, what do you just mean? Why did you suddenly say a whole bunch of strange things to me? Why can't we drink from the pool anymore? ”

I picked up the bag with water, looked thoughtfully at the transparent bag in front of me, and said without looking back:

"Because, I suspect, your uncle Li Zhenbo has put an excessive amount of arsenic in your water tank. Although this substance will be diluted by the sheer volume of the cistern, it will not affect the process by which it slowly accumulates in your body and eventually takes your life. ”

Hearing my words, Wang Yun's frightened face changed completely, and she rushed out of the house as if she was going to find her mother.

I turned around and found Ouyang Qian, who was standing outside the courtyard, looking at me with her hands folded.

After returning to the hotel, Ouyang Qian asked me:

"Team Shao, why did you insist that Li Zhenbo poisoned their pool?"

I took out the bag of water I had taken from Wang Yun's kitchen, then threw it on the table and explained to Ouyang Qian:

"What I was thinking before and what I was thinking about now was completely different. At first, I really thought that Li Zhenbo was simply committing suicide. Maybe it's because of loneliness, maybe it's because it's neurotic, or maybe it's because you can't get enough attention from your family and the people around you......

"But, this is a smart man. If you drink the poison and let yourself die, there is no problem at all. In that case, he's just going to be a joke on people's lips, not to get people's attention as I thought.

Therefore, a big reason for his suicide is, of course, because he thinks that there is nothing to worry about living in the world, and there is nothing worth cherishing. He is just a bachelor under the fence, with no family, no wife, and no ability to get himself out of this predicament.

"'I know, I'm nothing to the world.'" This is the content of his suicide note. But this was actually the truest thought in his heart, and it was indeed the truest situation he was in at that time. However, his suicide also attracted enough attention for his plan. ”

"Plan?" Ouyang Qian looked at me puzzled.

"That's right, it's the plan. If my guess is correct, Wang Huizhen's husband should have been very unhappy with Li Zhenbo a long time ago. Coupled with his character, punching and kicking Li Zhenbo is definitely indispensable at home. Living in this family is so aggrieved, one person will not be able to stand it. So......

So he simply set up this plan. He wanted to kill the people in his family, and let them be buried with him. So he waited for a time when the water would be cut off, and when the family had to use the water from the kitchen sink, he added an excessive amount of life-threatening arsenic to it, and then committed suicide to attract attention.

"As for the arsenic, it should have been obtained from Zhang Hua. But as for whether Zhang Hua is dead or alive now, I don't know. However, I believe that if Li Zhenbo is meticulous enough, if he really wants his murderous plan to succeed, then he should get rid of Zhang Hua.

"After all, it's suspicious for a quirky person to have a friend, isn't it?" I spread my hands and looked at Ouyang Qian in front of me with my eyes slightly open.

Ouyang Qian licked her lips and patted me on the shoulder.

"My man, it's just different, this can also be thought out by you, it's amazing! Ha ha! "She jumped on top of me at once and kissed me wildly.

And then...... It's a tender moment.

We took the car back to the police station the next day and handed the bag of water to our medical examiner's office for testing. As I expected, this bag of water was filled with an overdose of arsenic, which was diluted but still deadly.

When I got back, someone from the technical department called me.

"Team Shao, we have found Zhang Hua."

I rubbed to my feet all at once:

"Where?"

"In his hometown. He took a few days off work to visit his old mother. He was taking care of his mother in bed when we entered the house. ”

"Arrest him. This person provided a large amount of arsenic to another person, which was already suspected of endangering social security. ”

"Okay Shao team."
