Satomi Hoshino didn't ask again, Yan Shi quickly finished eating, cleaned up the dining table and took a shower before returning to the bedroom.

As soon as he lay down, he received a call from Wang Duo's seal.

Yan Shi: "Hey, Uncle Wang, what's the matter?" ”

Wang Duo: "That's the case, among the group of people arrested the day before yesterday, there is a student from your school, she sells drugs in the black market, but she should have a family above her, according to her, the place where that person traded with her is in your school, but it is not easy to install people in the school, don't I think of you, I will pick you up tomorrow and meet and chat." ”

Yan Shi: "Isn't that right?" When did you care so much about the police? ”

Wang Duo: "Hmph, even if you kid is smart, it's Chen Yan who wants to find you, and I'm just a messenger." Okay, let's talk about it tomorrow. ”

Early the next morning, Yan Shi, who had not yet woken up, was dragged to the police station by Wang Duo.

Chen Yan: "Yan Shi, I'm very sorry I still need your help, the school is really not good to place people, according to our guess, this girl's home should be in this school, according to her, every time the transaction location is in the school, every time the other party puts a book in the school's lost and found, there is a string of numbers in the book, every 6 numbers in a group, it is easy to decipher, the first 2 numbers are the number of pages of the book, the middle 2 numbers are the number of lines on the page, and the last 2 numbers are the number of words in the line. Together, they are the place of the transaction. Every time the place is different, but it is all in the school, when you arrive at the designated place, you will see a collection code, after paying, a book will appear again in the lost and found office the next day, according to the code in the book, you can see the hidden drugs when you find the location. ”

Yan Shi: "Well, wouldn't it be better for you to check the payee directly?" ”

Chen Yan: "Please don't insult the intelligence of the police, the strange point is that the collection code is different every time, and the payee is either a nursing home, or a welfare home, sometimes a caring person in the society, or a lonely old man without social security." ”

Yan Shi: "Is this person a fool?" What's in it for him to do that? ”

Chen Yan: "I don't know, we are also investigating the relationship at present. ”

Yan Shi: "According to what you say, even if you complete the transaction, you won't see anyone, where can you find it." ”

Chen Yan: "The difficulty is here, so I can only ask Yan Shi to see if there are any suspicious people who often appear in school recently." If there is a situation, do not act without permission, contact the police as soon as possible. ”

Yan Shi: "Okay, I'll try my best." ”

Yan Shi came home and saw that Tang Xiaotang had also returned, and asked, "How is the fun, is the capital prosperous?" ”

Tang Xiaotang: "It's not good, it's all human, I'm not used to staying with so many bugs." I bought you a gift, open it and take a look? ”

Yan Shi opened it and saw a watch with exquisite workmanship: "It should be very expensive, why is it so good to me?" ”

Tang Xiaotang laughed: "Of course it's to make you like me?" The book says that often creating romance will make the other person like you, and bringing gifts to the other person after traveling is a sign of romance. How's that, like? Did you find out that you already liked me? ”

Yan Shi: "This thing of yours is too valuable, I can't ask for it, you don't call it romantic, you are hitting me with money." ”

Tang Xiaotang: "Oh? Is it? Shouldn't gifts just be expensive to buy? ”

Yan Shi: "No, the gift needs to be intimate, if I were you, you might buy a pen, a pair of shoes, or a local souvenir." ”

Tang Xiaotang smiled: "I found out that I gave you face, and you really dared to teach me to do things." ”
