I rummaged around and searched every corner of the kitchen, but I couldn't find any nitrite caches.

I looked up and took out the small bowl they used to hold salt and MSG directly from the cupboard.

The most dangerous place is probably the safest place. I looked at the little jar of salt, white powder, and dipped it a little bit with my index finger, but I remembered that the difference between table salt and nitrite could not be distinguished with the naked eye, even in terms of taste.

I had to secretly bring a little bit and put it in a small bag, ready to take it back to the technician for identification.

When I came out of the kitchen, I found that Ouyang Qian had actually chatted with Hou Li! The two of them talked and laughed, and seemed to be talking very well.

Sure enough, they are all women in their 20s, and they can always find common topics easily. I walked out and pretended to be stern and said to Ouyang Qian: "What, Xiaoqian, have you finished asking all your questions?" Laughing so happily? Have you forgotten that we are working now? ”

When Ouyang Qian saw me like this, she immediately put away her smile.

I secretly rejoiced in my heart, but my face was still stern. I turned my head and asked Hou Li, "Hou Li, are you and your brother the only ones living in your house?" ”

Perhaps frightened by what I had just seen, Hou Li also looked at me a little scared and replied, "Well, well, it's just me and my brother." ”

"Do you have any good friends who often come to your house for dinner? Also, who are the people in your house who cook? ”

"Ah, it's such a police comrade, we have hired a cook at home, and he comes back to our house every day to cook." Hou Li explained.

I was a little surprised in my heart: this family can, and they have hired someone to cook the cooking.

Then I walked up to Ouyang Qian and asked softly if she had finished asking the question, and she nodded.

"Excuse me, when does your brother usually stay at home? If he doesn't come back, then we'll take our leave and visit your brother next time when he's home. ”

Hou Li looked at the time and said, "Then you go first, my brother's whereabouts for a day are relatively unregulated, but he often goes to bed late, so you may be able to come in the morning, he must sleep at home." ”

We nodded, said goodbye, and left her house.

As soon as I went out, Ouyang Qian pinched my shoulder fiercely.

"Team Shao, why were you so fierce to me just now! It all scared the hell out of me! She said coquettishly.

I said with a hippie smile: "Haha, I was joking just now, I just wanted to scare you, but I didn't expect you to really get tricked." ”

"Hate you!" She gently slapped me on the shoulder, and her face flushed.

After returning to the police station, there was some progress reported by the various investigation teams.

About Hou Yong, the owner of a local company, he is specifically wholesale low-cost food, similar to spicy strips and other cheap snacks. Partnered with a food processing factory. Because they have a wide range of sales channels, and many of the goods are directly bought from nearby schools, there are many stores that ask them for goods.

But according to his sister's description of him, although his company is running very well, this person often does not go home at night, often goes to nearby bars or Internet cafes to surf the Internet, lives a more romantic life, and spends money relatively quickly.

But the strange thing is that even if this person is so indulgent, his company has never had any major problems. And he was very good to his sister, gave her a house to live in, found her a simple job in the company, paid her a salary, and bought her all kinds of daily necessities.

As for Jian Honghong, he is a worker in a food processing factory that Hou Yong has a cooperation with.

Although nitrite is generally not directly used in food processing, some of the food processing raw materials obtained by nitrite through a series of chemical reactions are exactly what these factories need, so a large amount of nitrite is needed every day for processing in a factory like Jian Honghong's.

And the murderer is likely to get nitrite from this channel.

The person who delivered the food to Jian Honghong also found out his identity, he was the network manager of the Internet café, and he just helped a food delivery guy bring the food in, and the monitoring probe at the door of the Internet café also confirmed this, so we didn't pursue it, but found the courier.

Through the courier's description, we learned that he received an order from Jian Honghong on his mobile phone at 5:10 p.m. that day, and then went to the store to take the order, the name of the restaurant was "Lu Ji Xiao Fried", and Jian Honghong asked for a rice bowl with potato and beef stew at this store.

After the courier got the takeaway at the hotel, he drove straight towards the Internet café, without any stops and accidents on the way, but drove directly to the door of the Internet café, and then handed the takeaway to the network manager, and left directly and took another order.

Records from the courier's surveillance probes along the road also confirm that what he said was completely true.

In this way, our idea that someone got the takeaway before Jian Honghong and poisoned it was self-defeating. Because in the process of takeaway delivery, there is no third party to take over the takeaway.

Therefore, we had to directly find the source of this takeaway, the "Lu Ji Xiao Fried" restaurant.

This humble restaurant is located on a narrow but inexpensive restaurant that many of the workers working on the construction site eat at noon or evening after work.

The restaurants on this street almost all have the same characteristic, that is, the food is cheap and the taste is strong enough to suit the tastes of the workers. Many of them even choose to have a drink or two here.

"Lu Ji Xiao Fried" is on the street of the side street, so we found it at once.

Seeing me and Ouyang Qian wearing police uniforms, many people who were having dinner here stretched out their heads to look at us, and then exchanged their heads curiously, as if they were feeling sorry for the owner of this shop.

The hygiene of this small restaurant is not very flattering, and the dining table is dirty and greasy. In the small storefront, the floor is littered with used paper scraps and spitting out scraps of meat and bones, and the air smells of oily smoke.

I saw Ouyang Qian frowning: "Wow, Team Shao, the hygiene here is too bad, I can't believe how those people can eat their stomachs." ”

I thought to myself: but it's such a dirty little shop, and the home-cooked food is enough to taste, whether it's salt or chili, it's addictive.
