[Conan] He is always on the front line of seeking death.

The three people arrived at the platform and prepared to travel to Izu.

Then the three people were stopped by the young lady in front of the station.

"Hello, please give me your train ticket and ID. No dangerous items are allowed." A platform lady said to the three of them.

"Is it so strict today?" Jing Guang was a little surprised. Fortunately, they were not on a mission, otherwise it would have been very troublesome.

The two platform ladies looked at each other and sighed. The workload in the past few days was too heavy, and their throats were about to smoke. They said to Wang Ziyu and the others.

"A few days ago, there was an accident on the Hokutosei train that ran between Ueno and Sapporo on the first-class (limited express) sleeper train. Someone brought a gun inside and killed a passenger. The incident became a big deal, and that's what happened."

The Big Dipper train?

I remember when I wanted to take the train in my previous life, the Hokkaido Shinkansen was about to open and then the train stopped running.

I heard on the Internet that it is a very famous sleeping platform express train in Japan. It is also called the "Blue Train" because of its unique blue body paint.

The luxurious dining car where you can enjoy kaiseki and French cuisine, as well as complete facilities such as shower rooms, make the Hokuto Star very popular among passengers.

At that time, there was also the "Akebono" that ran between Osaka and Sapporo. It also stopped operating in the spring of a certain year due to aging problems.

I'm not sitting on it now...

"Oh my God, someone just brought a gun in..." Wang Ziyu was a little surprised.

Then do I have to reconsider the inspection level?

After thinking for a while, Wang Ziyu looked up and saw Jing Guang handing three false certificates to the young lady at the platform.

Wang Ziyu suddenly wanted to laugh. There was no need for the three of them to make drafts to fool the young lady.

Miyano Akemi's acting skills are also very good, and most people can't tell whether they are real or fake.

After all, the protagonist was fooled at that time.

Jing Guang's acting skills are also good, after all, he is someone who has been undercover in that organization.

That organization...

Wang Ziyu stopped smiling and looked at Jing Guang seriously. There were some signs of professional training. Although he was very suspicious in the eyes of outsiders, he was more in line with the personality of a bodyguard and could get rid of suspicion immediately after being suspected.

The acting is very good, there are no loopholes, and the expressions are perfectly controlled, just like a traveler getting ready for a vacation.

At this time, the lady on the platform saw Wang Ziyu looking at Jingguang seriously and said to Jingguang.

"Sir, your brother is very cute. He may have been paying attention to you because he doesn't know Japanese yet."

Here’s the young lady with a serious look on her face! Kawaii!

Wang Ziyu also noticed what the young lady said, so he smiled at the two young ladies without speaking in Japanese.

The two young ladies were a little excited, so cute!

No wonder everyone said that the little cutie is a good medicine for healing the soul. They both felt that they were much more relaxed physically and mentally.

Of course Jing Guang knew, his gaze was too direct and he didn't hide it at all.

Then he turned around and found Wang Ziyu smiling at the two ladies...

Not long after, the young lady finished the inspection and reminded her before leaving.

"In the tram, your pets need to be hidden. Don't be discovered by the conductor."

The three people thanked them and left, heading for the train to Izu.

Since there were nearly five hours, the three of them chose to sit.

And a little boring

Now Xiaoxuanfeng can't take it out, and neither can the cat. After all, he has to hide from the conductor...

Wang Ziyu turned to look at Jing Guang, who was silent next to him, and sighed.

I don’t know what’s wrong. Jing Guang seemed to be in a bad mood, and then the three of them stopped talking.

About three minutes later, Wang Ziyu took out the phone with some confusion and opened the bounty hall.

Suddenly it was discovered that a previous prisoner had disappeared.

His name is Anji Asama. He is a robber who has been working for many years. The last time he committed a crime was the robbery of a jewelry store a week ago. As a result, he was driven away by the owner of the jewelry store. Before leaving, the robber left a message, saying, "This has nothing to do with it." It's different'

Then... Anji Asama died?

Ok?

The person who fell to death from the train was pushed off by the jewelry store owner, who was planning to frame the blame...

Wang Ziyu was speechless when he saw the message. Kudo Yusaku seemed to have appeared at that time, so Conan should also be there...

But Sapporo is in Hokkaido, far away from Izu, so it should be fine...

This sentence was slapped in the face by me the next day, why!

But Wang Ziyu didn't know it yet, so he picked up the game console and pressed the buttons very quickly. Sparks and lightning flashed all over the screen.

The moves of the big boss on the opposite side are basically unable to hit Wang Ziyu, but the background is quite shocking.

This level is so difficult!

Mute the background music, then put on the big black headphones, plug in the MP3 and listen to the music, yes it is MP3.

In its previous life, it launched the world's first MP1998 player - MPManF3 in 10.

It was supposed to be released next year, but it was advanced several years. It was not available when I went to the United States ten years ago, but it appeared seven years ago for almost two years...

At that time, Wang Ziyu was a little confused, but because he had never used it before, he did not notice the strange time.

In fact, there was another reason. Wang Ziyu was playing the game while thinking.

MPMan, taken from the combination of MP3 and WALKMAN. The volume of MPManF10 is 70x90x16.5mm, which is about the size of four 1.44M floppy disks stacked together. It weighs 65 grams, which can be said to be very light. MPManF10 does not have any mechanical parts, the signal-to-noise ratio reaches 70dB, and the distortion rate is 0.01-0.1%. During playback, the audio track and playback time can be displayed, the playback sequence can be arranged, and it supports bass/midrange amplification, battery status detection and display, and can maintain 2 hours of playback with 8 nickel-metal hydride batteries. Even in the previous life, it will not appear to be lagging behind. .

MPManF10 was developed at the time to allow users to download songs from paid music websites. Unfortunately, Saehan did not have enough strength to promote it on a large scale. In addition, MPManF10 used flash memory, which was extremely expensive at the time, and soon became popular. Lost in the battle with MD.

Although it did not attract much attention, the emergence of MPManF10 has since launched the MP3 market, and many companies in South Korea have begun the research, development and production of MP3. To this day, South Korea still leads the MP3 field.

在世韩的MPmanF10为人们带来了惊喜之后，美国的帝盟（Diamond）公司挑头，于1998年底推出了RioPMP300，这是第一个让全世界都印象深刻的MP3。RioPMP300最大的优点就是可在互联网上下载MP3而不用花一分钱。

However, while the rich MP3 resources on the Internet have brought endless surprises and fun, they have also brought new issues of copyright protection. Diamond was soon targeted by the traditional record industry giant RIAA (Recording Industry Association of America), and took Diamond to court on the grounds that RioPMP300 infringed on intellectual property rights.

The matter eventually ended with Diamond winning the lawsuit, and the copyright dispute became the biggest publicity for RioPMP300. For a time, RioPMP300 became a well-known "star". It is worth 170 US dollars and is incredibly popular all over the world. Only then did people really know the existence of "MP3 players", leading many people today to mistakenly believe that RioPMP300 is the world's first MP3 player.

Later, more and more functions were developed, and it was almost like the first version of a mobile phone, with a camera, an e-book, a reading player, videos and a mobile hard drive...

Speaking of which, the first color screen MP3 came from China.

Wang Ziyu felt a little proud, it was amazing!

Later, after Wang Ziyu dismantled an MP3 player and thoroughly understood the principles of love, he built one himself, adding recording, storage and photo-taking functions.

The most important thing here is the algorithm problem.

mp3 algorithm.

MPEG-1AudioLayer3, often referred to as MP3, is one of the more popular digital audio encoding and lossy compression formats today. It is designed to greatly reduce the amount of audio data, and for most users, the playback sound quality is the same as the original There is no noticeable drop compared to uncompressed audio. It was invented and standardized in 1991 by a team of engineers at the Fraunhofer-Gesellschaft, a research organization based in Erlangen, Germany.

Simply put

MP3 is a data compression format. It discards data from pulse code modulation (PCM) audio data that is not important to human hearing (similar to JPEG which is a lossy image compression), thus achieving a much smaller file size.

Many techniques are used in MP3 including psychoacoustics to determine which parts of the audio can be discarded. MP3 audio can be compressed at different bit rates, providing a range of trade-offs between data size and sound quality.

The MP3 format uses a hybrid conversion mechanism to convert time domain signals into frequency domain signals:

*32-band polyphase integral filter (PQF)

*36或者12tap改良离散余弦滤波器(MDCT)；每个子波段大小可以在0...1和2...31之间独立选择

*Aliasing attenuation post-processing

According to the MPEG specification, AAC (Advanced audiocoding) in MPEG-4 will be the next generation of the MP3 format, although there are many important efforts to create and promote other formats. However, due to the unprecedented popularity of MP3, the success of any other format is currently unlikely. MP3 not only has extensive client software support, but also has a lot of hardware support such as portable media players (MP3 players), DVD and CD players.

……

I don’t know what happened, but an improved MP3 player was noticed by others soon after, mainly some large companies developing electronics. At that time, Wang Ziyu even received a recruitment contract from Bounty Hunter Online...

I remember that I was just bored at the time and wanted to listen to songs conveniently. Because of the times, the MP3 players sold outside used flash memory. Flash memory was very expensive and not as practical as a mobile phone...

So Wang Ziyu tore down the mp3 that he got from someone else...

Wang Ziyu's hand in playing the game suddenly stopped, and he didn't even care that the game was beaten to death, and he frowned and thought about it carefully.

That person...who is he?

Can not remember……

my head hurts...

Click, click, click...

The game console fell to the floor, attracting the attention of two people.

The two of them turned around and saw Wang Ziyu covering her head in pain with one hand, then falling backwards as if she had lost all her strength.

"Ayu?!"

"Ayu..."

My brain felt like it was going to explode. A deafening roar echoed in my mind. Only two anxious figures were left in my sight.

Then plunged into darkness.

so dark...

He seemed to be in a hazy and illusory night, with some faint lights below.

Where is this...

Wang Ziyu didn't think any more and passed out again.

But before he fell into coma, a figure seemed to appear in front of him!

"Prince Jade!!!"

Wang Ziyu woke up suddenly, gasping for air like a drowning person who just floated to the shore.

There was a looming figure on the car window on the side. He slowly sat up, turned his head, and looked at Wang Ziyu outside the glass.

Wang Ziyu looked at himself on the glass,

He looked confused and confused.

My eyes gradually penetrated the glass,

Looking confused at the scenery passing by outside.

There was no one around, and the sun began to set to the west outside. The warm yellow sunlight slanted downwards, shining on the interior of the car and the mountains and forests outside.

Wang Ziyu moved to the window sill and looked at the scenery outside the carriage in a daze.

The train passed quickly, and the woods not far away seemed to be shaken by the wind, and a few green leaves fell.

As soon as the sun shines through, it's like autumn has arrived. It turns yellow, streaking across the car, and then falls far behind.

Suddenly, a cloud covered the sun, the sunlight shining on Wang Ziyu's face disappeared, and the entire carriage went dark.

Wang Ziyu lay on the windowsill and looked up at the sky.

There are pieces of golden-red clouds under the blue sky, and the sunlight shining from the edge of the clouds and fog is clearly visible.

Wang Ziyu opened his eyes slightly

so beautiful

"It's beautiful."

A very familiar voice sounded from behind.

Ok?

Wang Ziyu turned his head, and Zhu Fu Jingguang happened to be sitting on the seat on the right, followed by Miyano Akemi.

Unlike Jingguang who was so relaxed, Miyano Akira asked with some concern.

"Has this happened to you often before?"

Wang Ziyu scratched his face and said awkwardly

"It's been almost two years. I thought it would be fine. After all, this hasn't happened for a long time."

Wang Ziyu sighed,

Who could that person be...

Wang Ziyu did not continue thinking.

"We have arrived in Wakayama Prefecture on the Izu Peninsula. Passengers getting off the bus, please pay attention to your luggage..."

As the train approaches the station, it begins to slow down.

After the train's announcement, the three people packed their luggage and got off the train along with a large number of passengers.

As they were leaving the station, a small policeman noticed the three of them.

Wang Ziyu and Zhu Fu Jingguang noticed the gaze and glanced at him with their peripheral vision, ah~ it was a policeman.

The little policeman stared at these three people. The atmosphere between them was a bit low, and they didn't look like tourists coming to play...

Could it be!

The little policeman had a bad suspicion in his mind.

It's a trafficker!

Just as the little policeman was about to take action, he stopped and said speechlessly

"Ah, it's a couple again..."

Another older policeman next to the little policeman heard what he said and followed his line of sight...

A cute child blushed, holding the hand of the man on the left with one hand, and the woman on the right with the other...

Looks like a family of three...

The older policeman withdrew his gaze and said to the little policeman next to him with a smile.

"I guess they were quarreling, and the kid was trying to make them reconcile."

"Well, I think so too...Senior, did you hear that!?"

"Ha ha……"

Wang Ziyu and the others couldn't hear these words. He is very shy now!

It's okay for him to hold Jing Guang's hand, but what has he done now! ! !

He held the hand of a girl who had a boyfriend!

It’s like connecting Jingguang and Mingmei! ! !

day!

"Haha, little Tianyu is so cute!" Miyano Akemi said with a smile, with some expectation in her eyes.

She had hoped for a long time that her sister could be like a child, live a carefree and happy life.

But the organization…

Miyano Akemi's eyes darkened, but they were just serious. The previous fear disappeared, and then she became as firm as diamonds.

The organization will definitely be eliminated!

It's like transforming from black, fragile graphite to pure, hard diamond.

Wang Ziyu and Zhufu Jingguang also felt the change in Miyano Akemi, and couldn't help but look at each other and smile knowingly.

The black organization is like a black useless stone that surrounds her. After the stone is cleared away, diamonds will appear. But now it is just a rough stone. If you want to shine, you need to polish the rough stone.

Wang Ziyu was very happy, and the first [polishing] was very successful.

The firmer the heart, the stronger the person!

The three of them took the train and arrived at Shirahama Town, Nishimuluo County, where they found a hotel with a tiled roof they had booked.

The three of them opened the door and entered the hotel to change their shoes. There was a dark-skinned man wearing glasses sitting behind the somewhat old counter. Hearing the sound of the door opening, he looked up.

Three people, two adults and one child, should be here for traveling. Kyogoku really thought about it and asked

"Do you three want to stay? Do you have a reservation?"

"Yes, we booked a room last night, and the guest who booked the room is named Gu Jing." Zhu Fu Jingguang said.

Kyogoku looked down at the notebook in the drawer on the counter, took out two keys and handed them over.

"We have a reservation, one double room and one single room, for three days from today to tomorrow. Please keep the keys well. If they are lost, you will be compensated at the original price."

After putting down their luggage and putting on their yukata, the three of them walked to the nearby fireworks display venue.

It's seven o'clock

There was still an hour before the start.
