As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

"It smells fishy. It's too late at 4am."

"Who do you think it could be?" Ye Lin asked.

Qi Shan tilted her head, raised her hand and said, "The fish seller, or the vegetable seller in the market, get close to the fish seller."

"Yes, yes, that must be it." Wang Longxin agreed, as if he had thought of it himself.

Ye Lin smiled and said, "No, it's definitely not selling fish or vegetables."

"How is that possible? Don't fishmongers have to set up their stalls early in the morning? That fits what you said," Qi Shan questioned.

"Yes. But have you thought about the time of the crime?"

"The vendors in the market buy their vegetables wholesale at 5 or in the morning and close their stalls at around in the afternoon. They don't have time to commit crimes."

"Also, this criminal is so familiar with the surveillance cameras in universities and hospitals. Do you think someone who spends all day in the vegetable market has time to observe these?"

Ye Lin asked questions in rapid succession, stumping both of them.

"Then brother, who do you think it is?" Wang Longxin gave up directly.

Ye Lin: "I think there is only one type of people who want to have contact with fish but don't have to squat in the market every day and get up early in the morning: the upstream suppliers of the fishmongers in the market."

Qi Shan responded: "You mean the person who delivered fish to the market this morning?"

Wang Longxin obviously didn't understand this, "What do you mean by giving away fish? Don't fishmongers bring their own fish to sell?"

"Where did the fish come from?" Ye Lin said unhappily.

"Eh...was the fish bought?" Wang Longxin said casually.

"You should go to the market more often. According to current sales theory, the market is the final sales terminal. They have suppliers above them. They ask the suppliers for goods, and the suppliers deliver them or they pick them up themselves."

"The vegetable vendors have already arranged the vegetables for sale today at the market before 6 o'clock. What time do you think they will pick up the goods?"

“What time do their upstream suppliers wake up?”

"Look at Xiao Qi, he has more common sense than you." Ye Lin said unhappily.

"I have been going to the vegetable market with my grandmother since I was a child. I should have been there more often than Brother Wang." Qi Shan said with a smile.

Wang Longxin, who was standing by, smiled innocently and said, "My mother doesn't take me shopping because she thinks I mess around with other people's things."

"Should."

After Ye Lin cursed with a smile, he said seriously: "Okay, we have decided on the general direction. According to the clues from the hotel owner, the scammers should be working in the area of ​​Yunshan Hospital. So we will expand 5 kilometers outward from Yunshan Hospital, find all the vegetable markets, visit fishmongers, and see who their upstream suppliers are?"

"set off!"

After that, Ye Lin rushed out with Wang Longxin and Qi Shan in high spirits, staring at Yu Haifeng in the office, "These three, they are quite excited about committing a fraud case."

......

There are a total of 5 vegetable markets within 5 kilometers of Yunshan Hospital, and some are scattered on the streets. Ye Lin thought that those should be supplied by the same supplier as those in the vegetable market, so he went straight to the vegetable market.

Taoyuan Market is the largest market nearby. There are 4 stalls selling fish and seafood. As soon as you get close, you can smell a pungent fishy smell.

Ye Lin came in casual clothes. Before he traveled through time in his previous life, he often went to the vegetable market with his grandmother when he was a child. The vegetable market at that time was much dirtier than it is now. All the vegetables were placed on the ground, and the vegetable sellers squatted on the ground. When it came to the place where fish were sold, the ground was full of water, and your shoes would get wet as soon as you stepped in.

The vegetable market now has changed a lot. At least every vendor has a cement platform, and there are no more puddles underfoot. It looks cleaner, but it lacks the smell of my childhood.

"Boss, is this fish fresh?" Ye Lin asked casually as he walked up to the first stall.

"From what you said, they were all delivered this morning, so they must be fresh. Look, they are still swimming vigorously."

"How about a sea bass? It's great." The boss greeted enthusiastically.

Ye Lin squatted down and dug a little with his hands. The fish in the pond swung its tail violently, splashing water.

"Wow, it's quite fresh." Ye Lin joked.

"How about one?" The boss took the net and prepared to catch it.

"I'm not coming. I just want to find out something." Ye Lin's face changed, he took out his ID and said seriously.

The fish boss narrowed his eyes. Although he couldn't see the words clearly, the national emblem on it was still very clear. His face suddenly became embarrassed.

"Comrade, I'm just a fishmonger. I haven't done anything bad."

"I'm not talking about you, I just want to know, are these fish sent to you by others?" Ye Lin asked.

"Ah, yes, all of them. The fish in these four of us were sent to us by others. It's the same for everyone." The boss pointed to several other fish stalls behind him.

"What time does it usually arrive?"

"Well, this is usually delivered around 5 in the morning, about this time."

"The driver brought it here?"

"Ah, use that kind of truck to pull it to the underground garage, and then we'll bring it back."

"Are they all delivered by a fixed driver?" Ye Lin asked.

"Well..." The boss thought for a while and looked at the boss lady next to him, "It seems to be about the same. Xiao Chen sent it today."

The proprietress looked up and said impatiently, "Before it was Lao Wang, now it's Xiao Chen, officer, have you finished your questions? We still have to do business."

Ye Lin smiled slightly, "Then bring me a perch, a big one."

The lady boss smiled brightly when she heard this, and pushed the boss aside, "Hey, our fish is great, I'll pick a big one for you."

After saying that, she reached for the dying fish. Ye Lin didn't say anything and let her weigh it and pay for it.

Holding the slaughtered fish, Ye Lin looked at the boss lady and asked, "Boss lady, are all the four of you delivered by one person?"

"No, we each have our own suppliers, but they are all similar at the higher levels, all of them are big companies."

"Then look at this person, is he Xiao Chen who delivered the goods to you?" Ye Lin took out the surveillance photo of the scammer.

The proprietress took a glance and shook her head, "Xiao Chen is a young man, tall and thin, it's not him."

"Is that Lao Wang who delivered the goods before?" Ye Lin asked.

"I can't say for sure. They look about the same height, and I can't see their faces, so how would I know?"

"Well, officer, you're welcome to buy fish next time. I won't treat you this time." The proprietress had sold the fish and didn't want to bother with Ye Lin anymore.

Ye Lin walked to the next few fish stalls and asked the same question again. Basically, it was the same as what the first stall said, all the fish were delivered in the morning. As for the deliverymen, Ye Lin also showed them, and they didn't look like him.

That is, Old Wang is a little bit suspicious. Ye Lin then went to several vegetable markets and got similar information.
