When Tang Youguang saw Mu Nan, although he was very surprised, he quickly understood the purpose of her trip, and still warmly received her and Su Weiqiang in the living room on the first floor, pouring tea and taking fruits, and was very busy.

After Mu Nan introduced Su Weiqiang to Tang Youguang, he went straight to the point, she didn't want to waste time. This time was different, she felt that Tang Yongguang was a victim, so she respected him very much, and kept calling him Teacher Tang, "Teacher Tang, it's very presumptuous to come and disturb you so late at night, I'll get straight to the point, and I won't hide some words." ”

"Well, well, Leader Mu, just ask, I'm Tang someone who knows everything."

"I'm your student, just call me Munan, if you're still so polite, it means that you haven't let go of my recklessness back then." She said this sincerely.

"Okay, good, Mu Nan, I'll call you Mu Nan." Tang Youguang also smiled gently.

"Do you know where my classmate Shanshan is?"

He smiled awkwardly, "I really don't know about that. ”

He was speaking sincerely, and judging by her intuition, he wasn't lying.

Tang Youguang said again: "I heard that you were the first person to suspect that Shanshan would poison me?" ”

"Yes."

"She's not going to poison me." He sat up straight, took a deep breath, and said slowly: "Mu Nan, you may not know that Shanshan's feelings for me are true, how could she poison me?" ”

"Maybe I'm too careful, but please be careful, don't be afraid of 10,000, just in case."

"I understand this."

"Have you felt nausea, vomiting, abdominal pain, diarrhea ...... recently?"

"Or are you coughing, chest tightness, shortness of breath, cyanosis, difficulty breathing, etc.?" He interrupted her without waiting for her to finish and helped her add the whole sentence.

She was a little embarrassed, but asked, "Do you have one?" ”

"Of course not, if there were, I wouldn't be able to sit here and talk to you a long time ago, either in the hospital or in the urn." His tone seemed a little impatient, but he quickly noticed it and immediately apologized for his tone, "I'm sorry, the people from the Public Security Bureau have been asking me this question every day these days, and I'm a little annoyed to ask me." ”

"Uh-huh." Of course, this good man understands, who wouldn't be annoyed by being asked the same question every day?

He then asked: "I want to check if there is paraquat in your house, especially the food you eat, is it okay?" ”

"Don't look at it!" He smiled wryly, "The police have already checked more than three times when they came." No, not as far as paraquat you are talking about. ”

But she was still not at ease, and asked him again, "What do you usually like to eat?" What to drink? Do you have any special dietary habits? ”

"Alas, when people reach middle age, they are either this or that high, so dare to have any hobbies, and those who used to have have quit have quit." This is also true.

"Have you taken any medicine lately?" She still didn't give up.

"What medicine?" Tang Youguang thought for a while and said, "Is the Liuwei Dihuang Pill counted?" ”

"Count!" She suddenly came to her senses, "Who bought it for you?" ”

"I didn't buy it." He knew what she wanted to ask, so he just said, "I bought it myself."

"Some time ago, I was a little dizzy, tinnitus, and my waist and knees were sore, and I went to the city hospital to see a traditional Chinese medicine, and according to the prescription prescribed by the Chinese doctor, I bought some Liuwei Dihuang pills in the city hospital."

"Gone?"

"It's gone." Tang Youguang nodded, but the other head was halfway up and lifted again, "Shanshan asked me to use honey water to deliver medicine." ”

"Did you send it?"

"Delivered!"

"Who bought it?"

"Who bought what?" Mu Nan's series of questions were asked too quickly, and Tang Youguang didn't follow up at once.

"Who bought the honey for the medicine?"

"I bought it."

"How did you buy it?"

"What and how did you buy it?" He didn't keep up again.

"Did I buy it online or in a physical store?"

"I bought it in a physical store." He thought for a moment, "But Shanshan said that she bought me a better bottle of honey for me at the online store." ”

"And what about this bottle of honey?"

"I haven't seen this bottle of honey." He thought hard for a moment, "That was a few days ago, Shanshan told me that she bought it for me, but then she disappeared, and I don't know where the bottle of honey she bought was?" ”

Mu Nan suddenly became excited, "Then hurry up and look for it, where is it?" ”

He smiled helplessly again, "No need to look for it, I told you just now, how many times have the policemen in this house been looking for it." ”

"Could it be somewhere else?" Mu Nan inspired him, "For example, these couriers, are there any collection points or anything like that?" ”

"We have a villa here, there are not many people living in it, there is no collection point at all, and they will usually put it in the letter house at the door when there is a courier."

"What letter house?" Now she was puzzled again.

"It's a bigger mailbox!"

"Oh, is there this bottle of honey in the letter house?" She stood up as if she were about to go to the letter house.

"Why hasn't it changed at all, it's still the same acute son." Tang Youguang actually smiled kindly, "Let's go, I'll take you to take a look." ”。

The three of them walked out together, and there was a small courtyard outside the villa, with a gate in front of the courtyard, and a small house covering an area of about two square meters to the left of the gate.

Tang Youguang pointed to the small house and said, this is the letter house.

Mu Nan sighed, it's really the life of a rich man, such a big letter box, no wonder it's called a letter house.

This letter house is full of express delivery, all of which are things purchased by Zhou Shanshan online, and it seems that Zhou Shanshan usually donates a lot to a certain treasure this week. The three of them rummaged for a long time, and finally found a courier labeled honey in this pile of couriers.

Mu Nan studied this courier carefully.

She first checked when it was delivered, the day before Shanshan went to her grandfather's house to pick up paraquat. At that time, she had not yet escaped, she should be at home, and she did not pick up the courier at home, which was unreasonable.

Mu Nan has studied the criminal police profession, and all things that are unreasonable are things that a criminal police officer must pay attention to. Then this courier arrived, and Shanshan didn't take it, then there must be a reason for this.

She first thought in her head, what was the most likely reason?

Two voices are in her sea at high speed.

The courier was bought by Shanshan for Tang Youguang, and why didn't she take the courier home at home?

Oh, that's how he wishes he could get it himself.

Why should he take it himself?

Oh, and that would prove that the courier didn't go through her hand, and that anything that went wrong had nothing to do with her.

What went wrong?

The honey in the courier contains paraquat.

So how did this paraquat get in?

It's certainly not a merchant, it's not a courier link, it's too tightly regulated to put paraquat in. Oh yes, it must have been after the courier put the courier in the letter house, and before Tang Youguang got the courier, Zhou Shanshan must have put the paraquat in during this time.

Yes, it must be. As soon as Mu Nan thought of this, he quickly brought the express delivery in front of him and observed it carefully. But to her disappointment, there was no trace of dismantling at all.

She still didn't give up, and brought the courier closer to the light, and looked carefully again, even if it was a place with a big needlepoint.

That's right, it's the point of the needle.

Mu Nan found a small hole with a large needle tip just above the outer packaging of the express.

She suddenly understood in her heart.

In order to confirm her thoughts, she asked Tang Youguang to find a knife and gently opened the outer package.

In the courier was a bottle, and inside the bottle was honey.

The side of the outer packaging with a pinhole corresponds to the cap, and there is also a pinhole on the cap corresponding to the pinhole.

That's right, Shanshan was the first to know when the courier arrived, and she used a needle to inject paraquat into the honey. After the injection, she did not take the courier, but continued to keep it in the letter house. After Tang Youguang found this bottle of honey, he would naturally take it back. These paraquat-containing honeys are then used to take the Liuwei Rehmannia Pills. Tang Youguang will slowly be poisoned to death.

Mu Nan told her reasoning to the two people present.

Su Weiqiang, who listened, secretly admired in his heart.

Hearing Tang Youguang, cold sweat broke out, and his hands and feet were cold. If he hadn't been exhausted by these policemen these days, he would have come over to get the courier a long time ago. Shanshan said that this is better honey, so he must have drunk this bottle first as soon as he got it. If that's the case, then he's what he started to say, and now he's either in the hospital or in the urn.

Tang Youguang drooped his shoulders and muttered, "I always thought she was true to me!" I always thought she was real to me—" His spirit was drained at once, and it seemed like he might fall to the ground at any moment.

"Teacher Tang-" Mu Nan hurriedly stepped forward to hold his arm, "Teacher Tang, are you okay?" ”

Su Weiqiang also hurriedly came up to hold his other arm.

This call was more timely, as if it had pulled his wandering soul back.

Tang Youguang sighed and said to Mu Nan: "Let's go, go and sit at home, and I'll tell you everything." ”
