"So, are you and Lin Xiaoguo lovers?"

The red-haired uncle unnaturally distanced himself from No. 7, and looked at the counter full of photos with a somewhat uneasy look, "No, it's not. That one was just a photo taken together when we went out to play during the holidays."

"Then do you know that Lin Xiaoguo has a male classmate with whom he has a very close relationship?"

The red-haired uncle subconsciously widened his eyes, and then quickly closed his eyes and looked like he was thinking. A slight drop of sweat appeared on the red-haired uncle's forehead at some point, "I'm really not sure about this, Mr. Lin." She didn't tell me anything about school."

No. 7 squinted his eyes and said a name, "Li Wanxiao."

"Isn't she a girl?" the red-haired uncle blurted out subconsciously, and then smiled awkwardly when he saw No. 7's half-smiling expression, "I heard Xiaoguo talk about Li Wanxiao once, saying that he wanted her to come here. It was her idea to find a job nearby."

No. 7 raised his eyebrows and continued to ask, "What about other than that?"

"No, no more."

"Oh, by the way, what is Lin Xiaoguo's mobile phone number?"

The red-haired uncle blurted out, "133xxxx7892."

"Thank you for your cooperation." No. 7 stood up, stretched out his hand and said, "Can you leave your contact information? If something happens, I will contact you as soon as possible."

"Sorry to trouble you! Please find Xiaoguo!" The red-haired man handed over his business card and grabbed No. 7 with both hands, "Please!"

After walking out of APPLE BAR, No. 7 took out the business card and took a look at it. There were red apples of different sizes printed on the white background, with the word APPLE BAR written in the center, and below that was the name and phone number: Red Tree, 133xxxx7891.

"Senior No. 7, what kind of relationship do you think there is between Hongshu and Lin Xiaoguo?"

Number 7 shrugged, "Well, who knows."

"Senior No. 7, where are we going next?"

"Go to the station first and investigate the surveillance inside." No. 7 said, taking out his mobile phone and dialing the number, "Taro, help me find out where Bai Jinhua from Class 2, Class 3, City No. 3 Middle School is."

————————————Central Station Management Office——————————————

On the 7th, he collected all the investigator IDs and said, "Stationmaster Liu, this is probably what happened. So can you investigate the surveillance video from 10:30 to 11:30 last night?"

Liu Feihong, the director of the central station, is a middle-aged uncle who is about to go bald. There is hoarfrost on the edge of the Mediterranean Sea. There are some obvious wrinkles at the corners of his eyes. He always has a gentle smile on his face and looks very kind.

"Last night's surveillance is on the desktop." Stationmaster Liu pointed to the desktop on his desk and said, "Recently, investigators have come to adjust the video every day, so every night's video will be copied to the computer the next morning. in."

"Okay, thank you."

"It would be best if the missing problem can be solved as soon as possible." Stationmaster Liu sighed helplessly, "Otherwise, the last train may have to be canceled. If it is serious, the entire central station may have to be closed. .So, it’s me who should thank you investigators.”

"You're welcome, it would be difficult for us to do things without your help."

"Haha, you guys go ahead and do your work first." Stationmaster Liu stood up and said, "I'll go outside for inspection."

"OK."

No. 7 and Luoluo hurriedly crowded in front of the computer, shook the mouse to release the sleep mode, clicked on the video folder named 2025.06.07 on the desktop and began to review them one by one.

After half an hour of hard work, No. 7 intercepted several pictures and saved them in a USB flash drive. "The first is the picture at the entrance of the central station at 10:36 last night."

In the picture, Hongshu and Lin Xiaoguo were holding hands and came to the ticket gate. Then Lin Xiaoguo stood on tiptoes and hugged Hongshu. The two kissed deeply for ten seconds before reluctantly parting. Let go of your hand.

"Wow, the two of them are really in a relationship." Luoluo was stunned, "No wonder, no wonder."

"Whether two people are lovers or not doesn't have much value for the time being. The next focus is on the back."

The screen fast forwarded ten times. About ten minutes later, Lin Xiaoguo, who originally entered the station alone, made a phone call and hurried out of the station.

Then, No. 7 opened another video. This one was a surveillance video of the waiting room. Lin Xiaoguo was seen bidding farewell to Hongshu and sitting in the waiting room looking down at his phone. After a while, a phone call seemed to come. After about a minute, he picked up his bag and hurried out of the station.

"Here, Lin Xiaoguo went out after receiving the call. As for where he went." No. 7 opened another video, "This is the surveillance camera located in the station square."

First, let’s talk about the topography of the station. Assume that the central station is located on the easternmost side of the map, connected to the north-south railway. Then the gate of the station opens to the west, followed by the station square occupying the middle of the map, and the APPLE Bar is located in the station square. To the south of , the mangroves and forest fruit in the picture are coming from that direction.

In the scene ten minutes later, Lin Xiaoguo left the station, turned right and walked north quickly. To the north of the square is the parking lot, and to the west of the square is a two-way eight-lane road. In the scene, Lin Xiaoguo passes through the parking station and continues to walk towards the station. North, and then disappeared from the surveillance screen.

On the 7th, he opened the Gu Ge map and drew in the direction Lin Xiaoguo left, "To the north is the parking lot, and then further north is a department store, Lily Community, Lily Primary School, and City No. 3 Middle School."

"What is she going to school for?" Luoluo asked, frowning.

"It doesn't have to be school." No. 7 clicked on another video, "Look, the time Lin Xiaoguo came back was 11:20, and the time he left the station was 10:46. During this period, there were three Fourteen minutes of free time. According to a normal person's walking speed of two meters per second, Lin Xiaoguo would only have walked four kilometers, a round trip of two kilometers."

No. 7 said and opened the scene of Hongshu and Lin Xiaoguo hugging each other and kissing, "But you also saw that Lin Xiaoguo is short, about 1.6 meters tall. Considering her strong physical strength, she is very fast." The traveling speed will probably not exceed one meter per second."

"One meter? Shouldn't it be one meter and four per second?"

"Girls usually have short legs and most of them have poor physical strength. Of course, except for sports students and girls who grew up doing housework, they normally walk slowly and at a constant speed. One minute is actually very short, and girls cannot actually walk very far. We also have to consider road conditions and traffic lights, so the speed will naturally slow down."

"Then look here again." No. 7 opened the screen of Lin Xiaoguo's departure and return. He saw that Lin Xiaoguo's schoolbag was thin and flat when he left, but it was bulging when he came back.

Luoluo said thoughtfully, "In other words, Lin Xiaoguo left the station to pick up or buy something? In this case, the trip should not exceed twenty minutes."

"Even if it takes her twenty minutes to walk quickly, the round trip is 1,200 meters, and the one way is 600 meters. Draw a circle with a radius of 600 meters with the station as the center." No. 7 used the drawing tool to draw a circle based on the map scale coefficient. Circle, there are only two places that are widened within this circle, "Lily Department Store and Lily Community."

Luoluo looked at the map and thought, "The department store building is 400 meters away from the central station, and Lily Community is 550 meters away from the station."

No. 7 watched these videos over and over again. Whether before leaving or after returning, Lin Xiaoguo did not do anything unusual in the station. He bought tickets, looked at his mobile phone, queued, and got on the train, even when the underground train left. There is nothing unusual about the entire station. Of course, this lack of abnormality is just that there is no abnormality in the picture.

"Buzz -" At this moment, No. 7's phone rang, "Hey, Taro... um, okay, got it. By the way, help me check Lin Xiaoguo's call records, um, okay."

"Senior No. 7, is there any news about Bai Jinhua?"

"Yeah." No. 7 nodded and looked at the map with a complicated expression, "Bai Jinhua goes to work in a department store every afternoon."

"Every afternoon? Doesn't he have classes?" Luoluo asked with a strange expression.

"Although he only attends half-day classes every day, his academic performance is good, so the school teacher turns a blind eye."

The corner of Luoluo's mouth twitched slightly, "You can really do whatever you want if you study well. Is Senior No. 7 going to meet him next?"

"It's half past twelve now, and there's still an hour before I go to work in the afternoon." No. 7 looked at his watch and said, "So let's go eat first."

"It's really time to eat." Luoluo touched his belly. He was so busy that he forgot to eat, "Senior No. 7, where should we eat?"

"Food court on the fourth floor of Lily Department Store."

"ah?"

————————————Food City on the fourth floor of Lily Department Store——————————————

The entire department store has seven floors in total. Excluding the two underground floors and the fifth floor used for offices, the entire fourth floor is a very large canteen. The hall is surrounded by small shops one after another. In the middle It is a neatly arranged dining area, where you can see a few scattered students in school uniforms, all students from nearby schools.

Luoluo swallowed her saliva as she smelled the aroma of vegetables in the air, "Senior No. 7, what should we eat?"

“Xiaoyun Fast Food.”

Looking in the direction pointed by No. 7, at the back of the store, a young man wearing a light blue chef's uniform was standing in front of the cutting board, cutting potatoes. His short black hair was wrapped in a red scarf, and his tender cheeks that had just faded seemed to tell the story. It was as if he had just grown up. In addition, there was an uncle sitting behind the counter looking at the recipes. This man must be the owner of this shop.

Luoluo's eyes widened inadvertently, and he said with some surprise, "That's Bai Jinhua?"
