The activity room was located on the high stone steps behind the football field, and I had always watched from afar before.

It was just after noon when I went, and there was no one in the activity room, and it was understood that students could only come to this activity room after school for club activities.

After climbing the high stone steps and pushing open the heavy glass door, I was really startled by the sight inside. The first floor is a platform for the display of honors, with trophies and certificates on both sides. I took a look at the fact that football, basketball, and tennis were all the best clubs in the same age group. The honor display platform is a small corridor with stairs at the end. Maybe there are too many clubs, and the specific location of each club hangs on the wall across the stairs.

"Culinary Club, Culinary Club." I muttered quietly.

"On the second floor, room 205." The captain pointed to a higher position.

I looked up, and the location was indeed something I didn't notice much of my height, and we confirmed the location and went upstairs. The second floor is the opposite of the first floor, and it is more spacious than the first floor.

Room 205 is easy to find, just follow the house number to find it, after all, it is not during school hours, the door of this room has been locked and cannot be entered. We looked to the side, and the door of the room next to the cooking club hung the words "Club Teacher's Office - Cooking Club".

Maybe it's not school time, and the hallway is quiet, which makes us unable to stop the sound we make no matter how quiet we are.

Just when we decided to knock on the office door, the door opened on its own. It was certainly not haunted, but a head peeked out from the inside of the door, and upon closer inspection was a young woman, about twenty years old. I think she's the teacher at the cooking club.

"Is there anything you guys are up to?" The woman said suspiciously.

The captain and I skillfully pulled out our police cards, and I thought that this young lady would be surprised, but I didn't expect her to be very calm. "Come in."

The office is also full of trophies and certificates, which is really excellent, I thought to myself.

"You may be seated." The woman motioned for the two of us to sit on the couch in the doorway.

"Hello, we are from the Municipal Criminal Police Team, and there are some things that you need to confirm." The captain said very politely.

"Okay, just ask me if there's anything, I'm a teacher in the cooking club, my surname is Tian, just call me Teacher Tian."

The captain took out his notepad, "May I ask Mr. Tian, what time did you get out of school on the 7th?" ”

"On the seventh, this is the first time I've been asked about this time, and if there is no accident on the seventh day, school will be out at half past six in the evening, and I remember that I haven't been in class this month." Teacher Tian said calmly.

"Do you know where Yang Qingyun's children went after school?"

"I don't know, she hasn't come to my class in the last two days, and I asked her teacher that she was sick. Did something happen to her? Teacher Tian said suspiciously.

Our protection worked, I thought to myself. Because the victim was a minor, we couldn't reveal that Cheongyoon had been killed during the investigation, and I said it in front of the convenience store owner, except for several school leaders and the family of the deceased.

"It's not convenient for us to tell you the specific problem, so can you tell me what kind of child she is in your eyes?" The captain put down his notebook and planned to listen carefully to Mr. Tian's answer.

"She is an excellent child, her academic performance is very good, and it is very rare to be able to participate in our club activities in addition to the intense study. At the same time, I think she is also very strong, you know, after all, the cooking club is cooking, and it is inevitable that she will hurt herself. Other children would cry and even quit the club, but she never did. The corners of Mr. Tian's mouth rose and he commented on Qingyun.

"Do you know any friends around her?" The captain picked up the notepad.

This is something to ask Hexuan, but don't worry, after all, Hexuan doesn't have time to commit crimes, I thought to myself.

Teacher Tian didn't think about it, "Well, she is a good person and is better than everyone, I don't know outside the cooking club, but when we are in class, he is always with a child named Su Hexuan." Because Hexuan's level is not good, and he came relatively late, the two of them are often divided into a group. Teacher Tian thought her answer was perfect. Someone asked this question a few days ago, and I thought you already knew it. ”

"That's a colleague from another department." The captain explained.

"Then what kind of child do you think Hexuan is?" The captain continued.

I actually want to hear what kind of student Hexuan is in the eyes of the teacher.

"Hexuan, he has a strong learning ability, and when he is grouped with Qingyun, he can always learn Qingyun's cooking skills quickly, especially Qingyun's learning of knife work. Qingyun's knife skills can be said to be one of the best in this age group, although they are not up to the level of a chef, but they are also very good, and Hexuan quickly mastered these skills after studying with her. But Hexuan's ability to cook independently is very poor, as long as we cook by ourselves, he is always the worst one. "Teacher Tian talks to us like he does with parents." I'm sorry, I don't know much about them, I only know their cooking skills and attitudes, and I don't have a deep understanding. Mr. Tian said with some apologies.

"No, I'm satisfied with your answer, oh yes, can you let me see what the inside of the activity room looks like?" The captain stood up and said with some pleading. I also stood up.

"Okay, no problem."

After Mr. Tian finished speaking, he took out the key and opened the door of the activity room next door. "You guys look first, if there's something to call me, I still have some things to deal with."

"Okay, please." The captain said politely.

The room is large, with several large tables in the center of the room, flanked by cooking tools. There are many photos posted on the walls of the room, and when you look closer, it turns out that they are photos taken by the students after cooking. Because food has an expiration date, it can only be recorded in this way.

I took a closer look, and from the first day of school this year to today, there was a wall full of stickers, "Look at what kind of dishes were made on the 7th." The captain commanded me, pointing to me looking at the picture.

"May 7th, May 7th. Oh here, it was dumplings made that day! ”

"Dumplings?" The captain asked rhetorically.

"Well, yes." Again, I'm sure.

"Did you say that you saw Hexuan go to buy soy sauce on the night of the seventh?" The captain asked knowingly.

"Uh-huh, yes. That day, he said he bought it because he had a supper. ”

After I finished speaking, the captain walked to the sauce and began to rummage, and I saw the captain take out bottle after bottle, bag after bag of sauce. "As I expected." The captain said, holding an unopened bottle of soy sauce.

"What's going on? What are you talking about? "I have some doubts.

"This bottle of soy sauce was not purchased by the teacher of the cooking club." The captain said as he put on his gloves and carefully held the soy sauce bottle.

"How do you prove it?" I was speechless at the captain's unfounded reasoning.

"You see, this soy sauce bottle doesn't have a "Cooking Club" sticker on it, but everything else is pasted. After speaking, the captain took out a brand new plastic bag and carefully put the soy sauce into it.

"Maybe I forgot to post it, but I can't say."

"I don't think so, you are taking a closer look at the brand of this bottle of soy sauce is different from the others, these two differences are enough to show that this is not a unified purchase by the teachers of the cooking club."

"What if not!" I'm a little unhappy.

"Hexuan is lying." The captain stared into my eyes.

"You're ridiculous, you said he didn't have the time to commit the crime. You're changing a little fast. "Even if he's my captain, I'm going to refute it.

"It's worth noting why you lie."

"Maybe it was brought before, how do you know that Hexuan hasn't bought soy sauce except before buying it this time?" I looked for the faint possibility to fight back.

"Let's go to his house one more time." The captain said as he tied the plastic bag in a knot. "Go and call Teacher Tian now."

I snorted.

"You're done searching?"

"Well, I don't know if we can take this bottle of soy sauce." The captain asked politely.

"Of course, you policemen, come here to get something, just a few days ago a policeman took that picture away." Teacher Tian complained.

"Which picture?" I asked next to me.

"It's just a picture of a cake, and it was hung on the wall before." Mr. Tian pointed to the photo wall.

When I got closer, I saw that a photo was missing, and the missing place clearly read "April 1st"

"Okay, I'll close the door if you two are okay."

"Okay, thank you, let's leave." I thanked the captain and left the activity room.

"We have to find a reason to go to Hexuan's house this time, it's not good to go twice in a row, you can, I'm his neighbor, how can I get along in the future." I walked out of the school gate and grumbled.

"It's not natural to find a reason to go into the kitchen anyway, let's just say that there are some things that need to be confirmed." After the captain finished speaking, he entered the door of our unit.

When we arrived on the thirteenth floor, the captain and I knocked on the door. The door opened again after a "click", and it was still Su Hai who opened the door.

"Policeman, is there anything else?" Su Hai said impatiently.

"We still have one more thing to confirm." After the captain finished speaking, he opened the door and went inside. I followed behind, too.

"Hexuan is not at home!" Su Hai said behind us.

"No, just borrow the kitchen."

The sauce of Hexuan's house is placed in the first sliding door from left to right in the cupboard, and I looked up and opened the sliding door, and there were all kinds of sauces inside. Because soy sauce is very common, it is placed in the first position.

"There are two bottles of soy sauce, there is not much soy sauce left in one bottle, and the other bottle has not been touched, this should be what Hexuan bought." I finished and took the unused soy sauce off the cupboard.

The captain also watched carefully next to me, and I turned the bottle, only to see a few big words written on the connection between the bottom of the bottle and the bottle body. A bad thought crossed my mind, and the captain patted me on the shoulder next to me.

"Let's go to a convenience store." The captain walked out of the kitchen, and I put down the soy sauce and followed.

I bowed deeply at the door, "Sorry to bother you." After saying that, I walked away, I could imagine Su Hai's surprised expression at that time, he must not know what we went to his house for.

"Can you confirm that your buy-one-get-one-free promotion here is from April 25 to May 1st?" I looked into the eyes of the convenience store owner and said.

"I can confirm that this is an event that is unique to our family. Just those days. ”

"Well, thank you."

Walking out of the glass door of the convenience store, I felt like I had been deceived. I still believe that Hexuan is not the murderer, but I am sure that he lied!

"Let's go, go back to the police station, and see how the situation is on Cao Yang's side." The captain opened the door.

Sitting in the police car that has been parked at the entrance of the community since the morning, the captain stepped on the accelerator......
