Japanese police can be roughly divided into two categories. One is criminal police, which is common in animation and Japanese dramas. They are responsible for solving various criminal cases. The other is public security police, similar to China's National Security Bureau, which is responsible for national security and intelligence collection. They have various powers including investigation, search, and arrest, and can use various types of investigation equipment and means.

The public security police system is huge, with tens of thousands of employees and has branches all over the country. However, except for the Tokyo Metropolitan Police Department, most of the rest are affiliated with the security department under the local police headquarters, and Osaka Prefecture is no exception.

Aoki Yosuke is a public security policeman affiliated to the garrison department of the Osaka Prefecture Police Headquarters. He graduated from a prestigious school, proficient in English and outstanding abilities. Unfortunately, because of his casual style and unique style, he was considered by his superiors not to be steady enough and embarrassing. He was still stuck in the position of the police department and could not be promoted. He was regarded as a waste and joke by his peers.

On the morning of September 4, 1995, as soon as Aoki Yosuke got to work, the section chief called him to the office, took out a thin folder, and ordered: "The International Intelligence Bureau of the Ministry of Foreign Affairs asked us to cooperate in investigating a person, and you will be responsible for this matter."

"How did the Ministry of Foreign Affairs come to us and question and investigate Americans or Europeans?"

"A Chinese man, this is his file, you can take a look first."

Aoki Yosuke took the folder, opened it and looked at the photos, and said in surprise: "Isn't this the 2 billion yen tech genius?"

In July, the famous Japanese gossip magazine "Wei Chuan" published an article introducing the legendary story of Du Qiu. The title was very eye-catching, called "Technical Genius or Criminal Genius? The mysterious history of the 2 billion yen rich man's fortune." Aoki Yosuke had a good memory and was deeply impressed by it, so he recognized it at a glance.

"Secretary, is this guy back to Japan?"

“The flight arrived at Kansai International Airport at 2:30 pm today.”

"It's coming in the afternoon, and I'm just arranged to go to work now, right?"

"Du Qiu has intelligence personnel from the Ministry of Foreign Affairs accompanying her. Your job is to assist her in making monitoring records because she is not good at English." The head of the section chief pointed to the folder and reminded: "The daughter of an American billionaire is also in the process. Don't disturb her, otherwise it will cause international disputes and you will not be able to save the police department."

"What's so great about Americans..."

While casually treating his boss, Aoki Yangsuke quickly looked through the documents in his hand, and then complained: "Before Du Qiu left home at the age of 8, his records after returning to China at the age of 22 were very detailed, but the 14 years he spent in Japan were blank. Where have he been? What have he done? Who has met? No records are there, how can I help me?"

"This is exactly why the Ministry of Foreign Affairs wants to investigate him. In addition, the Public Security Investigation Department of the Ministry of Justice is also investigating him. He has been invisible for 14 years without being discovered, which shows that there are major loopholes in our country's social supervision system and must be investigated clearly."

"Maybe he has super powers such as invisibility or deformation, so why not catch it and do scientific experiments." Aoki Yosuke joked, then picked up a photo of four people taking a secret photo at Chuncheng Airport, and enviously said: "Three beauties are walking together, and their love luck must be very good."

"Aoki, the Chinese government and Wall Street in the United States attach great importance to this person. Don't act rashly and report to me every day's monitoring situation."

"Hi, I'll be careful."

The next afternoon, Aoki Yangsuke reported to the section chief as required. After entering the office, he asked: "Secretary, do you know that the Shanshan Qianxin is actually a woman?"

Qianxin Shangshan was a famous general in the Warring States Period. He was known as the "God of War" and a historical figure who is well-known in Japan. The head of the section chief was asked inexplicably and frowned and scolded: "Aoki, what are you talking about?"

"Secretary, Du Qiu took his three girlfriends to Osaka Castle Park today, chatting about Warring States figures and stories all day long, and even told Kenshi Katsushima to be a woman." Aoki Yosuke pointed his forehead with his finger and said, "If I go to the history exam now, I should be able to get full marks."

"Did he talk about his previous life in Osaka? For example, where he lived or someone he met?"

"No word is mentioned."

"Then keep listening."

"Hi……"

On the afternoon of the third day, Aoki Yosuke walked into the head of the department head's office again and asked: "Child Director, do you know how many sub-brands there are under Shiseido, Kao and Kalibao? Do you know how to match the clothes of Yamamoto Yoshiji, Miyake Ichisaki and Kawabo Kurei?"

"Did they go shopping today?"

"Yes." Aoki Yosuke pointed his forehead with his fingers, and said, "If I go to the interview with "vivi", I should be able to be the editor-in-chief."

"vivi" is a famous female fashion magazine in Japan. Its style is between cute and mature. The readers are mainly female college students and office clerks. Almost every young female staff in the police headquarters owns one, so the bald and greasy uncle in his fifties is not unfamiliar with the head of the section chief, and he guessed: "So that Du Qiu has done fashion-related work before?"

"Maybe he did it, maybe not. I heard that his memory is far superior to ordinary people. He may have told the content of the magazines he had read before." Aoki Yosuke spread his hands and said helplessly: "There are too many fashion magazines in Japan! Most of my monthly salary is taken by my wife to buy cosmetics."

"Yeah, there are too many fashion magazines, my two daughters..."

On the afternoon of the fourth day, Aoki Yosuke walked into the department head's office again. This time, he did not take a free hand, but brought a takeaway food box and said, "Class Master, do you know how many kinds of ramen there are in Japan? Do you know how many kinds of octopus flavors there are?"

"So they must have gone to taste the food today. Osaka is the World Kitchen. No tourists who come here are not conquered by the food."

"Yes." Aoki Yosuke put the food box on his desk, nodded his forehead and said, "If I go to Daoduon Food Street now..."

"You can be a chef." The head of the section chief had learned to answer questions and pointed to the food box and asked, "What is this?"

"Osakayaki, Du Qiu made it himself in a snack bar."

The head of the section chief was startled, stood up with his hands on his desk, and shouted, "His he discovered you?"

"No. Du Qiu made a total of more than a dozen. I pretended to be a passerby and bought it from him." Aoki Yosuke opened the food box, took out two pairs of chopsticks, and said with a smile: "Secretary, let's try it together. The food cooked by the rich man with 50 billion yen is not something that everyone has the opportunity to taste."

Osakayaki is one of the representative delicacies in Japan. It is made of eggs and flour, and is made of seafood, meat and vegetables and other ingredients. As soon as the food box is opened, the rich aroma rises. The slightly browned bread, green and fresh vegetables, and the shrimps and squids are decorated with it, as if it is a beautiful landscape painting. The head of the department couldn't help swallowing, took the chopsticks and asked, "What 50 billion yen?"

"Du Qiu's company is said to have reached 500 million US dollars, equivalent to 50 billion yen."

"It's so amazing. I remember it was only 2 billion two months ago."

"Isn't that..."

The head of the department picked up a piece of divided Osaka roast and stuffed it into his mouth. He felt that it looked crispy on the outside, soft on the inside, and tender on the inside. It was one of the most delicious Osaka roasts I had ever eaten in my life. So before he could swallow the food, he inferred firmly: "He must have been a chef in Osaka before, otherwise he would not be able to make such an authentic Osaka roast!"

Aoki Yosuke nodded repeatedly, expressing his full agreement.

The two of them swept the clouds and quickly wiped out a box of Osaka Burning. After eating them all, Aoki Yosuke stood attentively, and said with a serious expression: "Secretary, Du Qiu is going to Kobe tomorrow. I want to continue listening with me. Please allow me!"

"Kobe is the place where the police headquarters in Hyogo Prefecture is responsible, and we have no right to cross the border and listen."

"The police in Kobe are all wastes. I secretly went there and would not be discovered."

"Nothing! I won't approve it."

"Then I'll apply for a few days off." Aoki Yosuke changed back to his hippie face and touched his stomach and said, "I ate too much delicious food today and have gastroenteritis."

The head of the section chief looked at the empty food box on the desk, hesitated for a moment and nodded and said, "Then you have a good rest."

"Thank you, Section Chief."

When Aoki Yosuke went out, the head of the section chief called him and reminded him: "Remember to come to me to report after rest."

"Hi."

On the afternoon of the fifth day, Aoki Yangsuke did not report on time, which made the head of the department who had been waiting for all day feel lost. Fortunately, on the morning of the sixth day, as soon as he walked into the office, he saw Aoki Yangsuke who was waiting inside. He was in a good mood and asked on his own initiative: "What questions are you going to ask me today?"

"Du Qiu returned to Osaka last night and was preparing to go to San Francisco this afternoon." Aoki Yosuke was a little listless and did not respond. Instead, he raised the thick document bag in his hand and said, "This is the monitoring text record during his stay in Osaka."

The head of the section chief has known Aoki Yosuke for almost ten years. This is the first time he has seen him so depressed. He asked, "What's wrong with you? You really have gastroenteritis, right?"

"Secretary, I think we made a mistake."

"What's wrong?"

"I didn't find Du Qiu when he was at the trough of his life, and then left him in Japan." Aoki Yangsuke touched his thick beard in recent days and said regretfully: "His departure is a loss to our country."

The head of the section chief thought he was too exaggerated and said disapprovingly: "The assets of 50 billion yen are a lot for individuals, but they are irrelevant to Japan as a whole."

"I'm not talking about money, but talent. Du Qiu has talents that ordinary people cannot imagine in many fields, and is an all-rounder among geniuses."

The head of the section still disagreed and joked: "Is it considered talent to know some history and fashion knowledge? He is indeed very talented in cooking. He cannot eat the Osaka Chili he made often, which I admit is a loss."

Aoki Yosuke smiled ritually, then bent down and took out a small tape recorder from his briefcase and said, "Yesterday at dusk, Du Qiu sang a song in the American Park near Kobe Port. I transcribed it and let me hear it for you."

"What song?"

"He said it was a song he wrote after his adoptive father passed away."

Aoki Yosuke put the recorder on the desk and pressed the play button. The tape slowly turned, and the sound of a man singing came from the sound of a light and a little low. There was no instrumental accompaniment, only the vague sound of wind and waves, and occasionally the sound of seabirds singing.

"I thought about it all over again..."

"It's because the black-tailed gull is chirping at the pier..."

"With the waves, they float and sink..."

"Pede my past and fly into the distance..."

“…”

After 50 years of class, he has long been no longer interested in music. He has no feelings for the first few sentences, but when he heard the four seemingly unrelated lyrics of "mint candy, a fishing port lighthouse, a rusty arch bridge, and an abandoned bicycle", he was suppressed for years and years, and his emotions, like a dry well, suddenly fluctuated violently. A series of beautiful memories of childhood and youth flashed in front of him. However, these beautiful memories turned into yellowed photos in the blink of an eye, floating in the passing time and could no longer be recovered.

"I thought about it all over again..."

"It's because I haven't met you yet..."

"People like you exist in this world..."

"May I like this world a little bit..."

“…”

The song was played quickly in less than 5 minutes. Neither of the people in the office spoke. After a quiet silence for a while, Aomuyang said, "I re-watched the Romance of the Three Kingdoms filmed by China last year, a passage of what Cao Cao said to Liu Bei is very suitable for Du Qiu."

"What's the matter?"

"I can't remember the specific lines. It probably means that dragons can be big and small. When they are big, they can fly into the universe to suck clouds and mist. When they are small, they can hide under the waves and make people unaware of them." Aoki Yangsuke unconsciously imitated Cao Cao's tone in the TV series and commented: "A person who can hide for 14 years and cannot be detected by the entire Japan must be an amazing genius. When he takes off, he will definitely fly very high."

The head of the section chief still disbelief and asked, "Have you found anyone who knows him in Kobe?"

"No, Du Qiu was wandering around the street with a swagger, and no one knew him."

"So where was his residence before leaving Kobe?"

Aoki Yosuke spread his hands and said helplessly: "Du Qiu has visited the entire Kobe, and has not deliberately searched for a certain place to stay, nor has he stayed in a certain place for a long time."

"How could this happen? Don't he want to find his adoptive father's belongings?"

"He dug a small bag of soil near Kobe Port, as a souvenir of his adoptive father, and then left." Aoki Yosuke said here, knocked on the file bag on his desk, and said, "He read two lines of poetry in Chinese at that time. I don't understand. Please find someone to translate it."
