"Uncle Zhao, where did you sell this kitchen knife?" After Zhao Shuo and Xia Xi sat down, they suppressed their excitement and immediately asked.

"Kitchen knives? Could it be that there is something wrong with this kitchen knife? I've been using it for a few years now and I don't see anything wrong! Uncle Zhao was very sensitive and immediately asked.

"No, no, that's right. This kitchen knife is exactly the same as the one used by the murderer in the case upstairs today. Xia Xi hurriedly explained.

"O'O, it's no wonder that seventy or eighty percent of our residents here use kitchen knives like this. Not to mention, this one is really good, it has been used for a few years, the knife edge is sharp, the blade is stainless steel, and the quality is better than the kitchen knives sold on the market. Zhao Shuo praised.

"Ao, Uncle Zhao's kitchen knife was not bought on the market." Xia Xi grasped the point and immediately asked.

"Of course, there are no such good knives on the market now!" Uncle Zhao recalled and continued: "More than two years ago, when I first came to Qingzhou to rent and live here, a knife seller came, and most of the people in the community bought it at that time. ”

"However, the strange thing is that he has not come to collect the money for more than two years." Uncle Zhao also found something unreasonable.

"Uncle Zhao, what the hell is going on, why did you say that the knife seller didn't come to collect the money?" Xia Xi asked anxiously, there must be something wrong here.

"Ao Ao, we don't have to pay for the kitchen knives we buy for the time being, there are often such people in the countryside, and we call the people who sell knives like this 'knife people on credit'. Ordinary people, love to take advantage of a little cheap, this kitchen knife does not need money for the time being, everyone must rush to buy it. Uncle Zhao said.

"Hey, after so many years, I haven't come to collect money, and many people who buy knives have moved to an unknown place, where to collect money. If you sell knives like this, you will lose your pants. Uncle Zhao sighed.

"Uncle Zhao, does the knife seller say when he will collect the money?" Zhao Shuo frowned, it seems that this "credit knife man" is not easy to find.

"Let me remember, Ao, I heard him babble at the time: When Qingzhou Dalin, the black rain is 7749 days, he will come to collect the kitchen knife money. We all laughed at him at the time, how could it rain black in the sky, and God bless Qingzhou, the wind and rain are smooth, how can it rain for forty-nine days in a row, such weather is not recorded in thousands of years of history. Zhao Shuo smiled, feeling that there was something wrong with the nerves of this "credit knife man".

"Knife man on credit"!? Zhao Shuo and Xia Xi glanced at each other, and they both felt that it was incredible, there is such a profession in modern society?

"Haven't you seen the 'Knife Man on Credit' since last time?" Xia Xi asked.

"I haven't seen it, but others say that he has sold it in other neighborhoods. They are all poor neighborhoods, and the rich don't look down on these stalls. Uncle Zhao glanced at Zhao Shuo and Xia Xi and said with a smile.

"Uncle Zhao, do you remember that Xiao Zhang, who committed the crime upstairs, bought it?" Xia Xi asked.

"There were so many people buying at that time that I was in a hurry. Wait, I seem to see Xiao Zhang's wife is also there, she should have bought it too. Zhao Shuo recalled bitterly.

That's right, all the questions point to the kitchen knife, to this mysterious "credit knife man".

"Uncle Zhao, do you roughly estimate how many people in your building came to buy kitchen knives on credit at that time?" Zhao Shuo frowned and asked, he muttered silently in his heart, hoping that fewer people would buy kitchen knives as much as possible.

"I'll take note of this. Except for a few who were not at home, basically everyone bought them. Zhao Shuo said truthfully.

This building has seven floors and three units, according to each unit plus 16 households in the corridor, there are about more than ten households in the back, and there are a total of seventy or eighty households in this building, that is to say, there are at least sixty or seventy households selling knives!

As soon as the accounts were settled, Zhao Shuo and Xia Xi were stunned! His face became unusually ugly.

If there's something wrong with these knives, it's a big deal!

Moreover, this is only one such building, in this shantytown, I don't know how many such buildings there are, roughly estimated to be a hundred and ten. In Qingzhou, there is definitely more than one such shantytown!

They don't dare to go any further, it's absolutely appalling and terrifying!

"Xiao Shuo, you say, is there really a problem with this kitchen knife?" Uncle Zhao noticed that the two of them had abnormal faces and asked suspiciously.

"Uncle Zhao, let's not hide it, we judge that there may be something wrong with this kitchen knife, but we still need to verify it further." Zhao Shuo said with a wry smile.

When he knew this fact, he also felt that the matter was important, so he spoke a lot more carefully.

"Uncle Zhao, do you remember the appearance of that mysterious 'credit knife man'?" Zhao Shuo asked.

"Have you a little impression, do you want to find him? I advise you not to bother with it, those 'credit knife people' are all over the world, they are at home everywhere, and they don't know if they are still in the world, no one knows. Uncle Zhao sighed, if it weren't for the compulsion of life, who would want to be a "credit knife man".

"Officer Xia, please arrange a portraitist now, immediately draw the portrait of the 'credit knife man', no matter where he is in the empire, he must be found out, so that the real culprit can be found." Zhao Shuo gave instructions solemnly.

"Well, okay, I'll arrange it." Xia Xi also knew that this matter was urgent, and immediately reported the arrangement.

"Uncle Zhao, can you please do one thing, that is, sell me this kitchen knife."

"Of course, since you think there's something wrong with this knife, I'll give it to you. I've got other kitchen knives, don't worry. Looking at the Yanxia coins handed over by Zhao Shuo, Uncle Zhao refused again and again.

Zhao Shuo took out a pair of plastic gloves, carefully removed the kitchen knife, and put it into a special evidence box.

"It's okay, it's the same as I estimated. As long as your skin is not next to the kitchen knife, the black fog inside the kitchen knife will not come out. He breathed a sigh of relief.

What Uncle Zhao didn't know was that it was because Zhao Shuo took his kitchen knife in time and saved the lives of their family of two. Of course, that's an afterthought.

"Uncle Zhao, can you trouble you and go to each household with us to collect such kitchen knives? Of course, we will pay 2-3 times the market price. Xia Xi's eyes lit up when he saw Zhao Shuo's movements, and he immediately made up his mind.

"That's fine, I'll take you there." Uncle Zhao said enthusiastically.

Taking advantage of the fact that the portraitist had not yet come, Uncle Zhao took the two of them to collect kitchen knives from door to door.

Fortunately, all the residents were very cooperative, and after paying the money, they were willing to sell them the kitchen knives.

After turning around, Zhao Shuo had already sold more than 50 of the same kitchen knives, and some people were not at home, Xia Xi marked them one by one, and told the neighbors a thousand times, asking them to convey: You must wait for them to come and collect them at night, and you must not use kitchen knives before collecting them.
