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

The sun will set in half an hour.

Wang Ziyu was still thinking.

Sun, sun, light...

Wang Ziyu turned to look at the sun outside the window.

Sun, solar energy! ! !

If this is the case for me, then the X of XX means... between the railroad tracks.

Wang Ziyu looked at the paper he drew before.

It has so-and-so written all over it

One of them is between the railroad tracks!

"A Jing! Found it! Hurry! Send it to... the police!"

Wang Ziyu said loudly to Gu Jing directly.

At this time, Conan was still in the corridor, talking to the doctor.

"Shinichi, your solar skateboard is with the police. Remember to pick it up later." Dr. A Li said to Conan.

"Speaking of which, the principle of this bomb is exactly the opposite of that of my solar skateboard."

Seeing Conan raise his head in confusion, he looked at Dr. A Li.

The doctor explained.

"It can be seen that the power source of the bomb must not be solar energy, otherwise it would not be able to move when the sun goes down."

At this time, Conan had a flash of inspiration and discovered it.

"The sun...solar energy!"

"Doctor, I understand!"

At the same time, the prince and Gu Jing were in the room.

"Solar energy!" Wang Ziyu hit a high note.

Then take out the paper, tear it off directly, and write the formula on it.

Write and talk at the same time.

“The location where the prisoner planted the bomb was between the railroad tracks!

Those five bombs have been designed by the prisoners. If the bombs are not exposed to light for a few seconds, they will detonate.

If a circular line train passes over a bomb, if the entire train passes completely, the light will be blocked for a few seconds..."

Wang Ziyu calculated the formula directly.

Preach while writing

“一节车厢的长度以20公尺20米计算，10节车厢就是10x20等于200公尺200米

Keep the speed at 60 kilometers per hour

60x1000÷60÷60=16.6666……

It is approximately equal to 16.7 meters per second, which means that it takes 200 or about 11.97 seconds to cover a distance of 12 meters.

If you don't want the bomb to detonate without light, drive at a speed exceeding 60 kilometers per hour. The bomb will return to zero in time, so it will not detonate. "

"Just let the train leave the circular line and transfer to other tracks! There will be no danger of stopping!!!"

Wang Ziyu stared at Gu Jing and said loudly.

"it is good"

Gu Jing looked at Wang Ziyu who was serious, and then sent the information to the police.

Then Wang Ziyu silently logged into the bounty hunter account.

染！

online

Public security private message mission...completed!

At the same time, the two people in the train also discovered the key point of the problem while maintaining order.

Why do bombs explode when the sun goes down?

sun……

Matsuda and Hagiwara looked at the train track ahead at the same time.

Then he quickly called his superiors.

Just like a drama, three groups of people used different information in different positions and hit the key points at the same time to find the same correct result.

at the same time

Criminal Investigation Division 1 of the Metropolitan Police Department Criminal Investigation Division 3

Security Planning Section, Security Bureau, National Police Agency

Explosives/Explosives/Objects Disposal Team of the Mobile Team of the Metropolitan Police Department’s Security Department

All received the information

Three of the four reports were sent to the Metropolitan Police!

The fourth message, dye!

Wang Ziyu continued typing.

[Bomb location information: Between the tracks on the Toto Circle Line

A place where there are no walls or buildings blocking the light

Pay attention to the position of the sun when searching

Be careful to avoid your shadow covering the bomb. ]

[OK, the bounty will be settled after the bounty mission is confirmed to be truly completed]

Wang Ziyu thought for a while and added another sentence.

[The fax sent by the bomber to the Metropolitan Police this year should be 0, right? ]

[Yes, it’s the Metropolitan Police Department, that’s right. ]

[I don’t know if the bomber regrets it now]

The person on the other end of the email smiles.

He still remembered that the bomber's nose was bruised and swollen when he was sent here...

When the prisoner knew that he had affected a bounty hunter, his expression...

"puff."

The person on the other end of the email smiled.

[Then where are you today? ]

Wang Ziyu saw this email.

[Another test... Why do you think I will stay on that train for half a day? ]

[possible. ]

[I think you should be checking now...]

In fact, the people on the other side of the email are actually checking...

[What happened to the bomber this time? ]

Wang Ziyu became more energetic and asked.

After all, the information he currently has is still too little.

[…because of your teacher? ]

Wang Ziyu read it and wrote:

[After all, he is Chinese, and the crime rate in Tokyo is a bit high... My little teacher was kidnapped on the first day he came here, and then bank robbers, murderers, drug smugglers, etc. , bomber...it's only been a month. ]

[...]

The person on the other end of the email was a little speechless. Among bounty hunters, Ran was known to protect his shortcomings... and the crime rate in Tokyo was a bit high.

After a while, half an hour later, all 20 trains left the Tokyo Loop Line.

After 15 minutes, all five bombs were collected.

I also got 40 yen.

Wang Ziyu was very happy.

[Where were the bombs found and sent to me? ]

The person on the other side of the email sent the information to Ran by the way.

Because Ran sometimes would do a few small favors for free when he was happy.

Ran seems to be very happy now.

After everyone left, Conan also left with Uncle Maori.

After all, his injuries were not serious, and he could learn more information by staying with the police.

Wang Ziyu was typing on the computer while chatting with Gu Jing Miyano Akemi.

"The timer for the pet basket suddenly stopped in the children's playground today, but there is no possibility of a criminal in the nearby apartment. Why?"

Wang Ziyu was still thinking at this time.

I remember when I was a kid, I only watched the first one or two episodes of the anime and then never watched it again.

I just heard, what movie version is out?

what name?

What's the general story?

But Wang Ziyu mostly forgot.

After all, you can't get extra points for memorizing those things in the exam...

At this time, the other party's information was also sent.

Most are next to residential areas.

However, one of them is on the bridge.

Sumida Canal Bridge!

While investigating this bridge, I discovered

It was built in 1983 AD. It was not an iron bridge, but made of British-style stones. It caused a great sensation at the time, and the builder

Moritani Teiji also won the Japan Architectural Association's Best Newcomer Award for the bridge.

Miyano Akemi looked at the TV and said, "There have been so many arson cases recently, and the Kurokawa House is also on fire."

Gu Jing glanced there and said, "Many of the houses that were burned were axially symmetrical."

"Huh?" Wang Ziyu glanced over there.

Moritani Teiji's architectural passion was axial symmetry.

It is said that the name was changed at that time in order to pursue symmetry...

A perfectionist...

After searching a bunch of information, I found that all the houses that were set on fire were designed by Moritani Teiji.

There is also a rice flower municipal building

When I continued to investigate the Mihua Municipal Building, I discovered that the Mihua Municipal Building is not a completely axially symmetrical figure!

Wang Ziyu swallowed.

Take a look, it's past 9 o'clock now.

Continue to investigate these houses that were set on fire. They are all works designed by Teiji Moritani in his early thirties!

However, there was no explosion attack, and the street lights in the children's park that stopped the bomb had a standard axially symmetrical shape. When Teiji Moritani went to study in the UK, he saw the London-style gas lamps.

Works by Teiji Moritani.

By the way, the houses with arson cases found on the Internet are not standard, and the axially symmetrical graphics have been modified to some extent.

Wang Ziyu opened his email account.

[Are you there, the suspect Moritani Teiji? ]

[How did you get it done? ]

People over there are still a little confused, so fast?

[Mizushima family, Yasuda family, Akutsu family, and Kurokawa family.

The Sumida Canal Bridge at the time of the explosion in the afternoon was all the work of Ritsu Moritani in his early twenties and thirties.

There is also the location where he suddenly stopped when he bombed and counted 1 in the afternoon.

The street lights in the children's playground were designed by Teiji Moritani. I saw the standard axially symmetrical graphics and they were flawless.

The above-mentioned buildings that are about to be destroyed have all been modified and have defects, and can be found online.

By the way, there is another one with flaws, the Rice Flower Municipal Building. ]

[Then why did he say it was a challenge to Kudo Shinichi? ]

[In the case of Nishitama City Mayor that Kudo Shinichi solved last year, which indirectly prevented the construction of Nishitama-style new town, the designer was Moritani Teiji. ]

[Are you sure? The Mihua Municipal Building is very important. ]

[There is a high probability that I am monitoring the Chamihua Municipal Building to see if Teiji Moritani appears there. Judging from his life experience, he is a perfectionist. To be honest, I have an intuition that he is the bomber. ]

[But now you are just looking for evidence? ]

The people over there were a little helpless.

[Yes, and there is enough leftover to blow up the Mihua Municipal Building. ]

Wang Ziyu continued to click on the computer, checking the surveillance with Gu Jing and Miyano Akemi.

Then all three people saw the figure of Moritani Teiji

Carrying a large bag, he appeared at the emergency exit of the stairs on each floor and placed some things.

All three of them looked a little bad.

Wang Ziyu immediately made a decision and directly packaged the screenshots of these videos and sent them to the person on the other side of the email.

[The little he carried was not enough for the remaining 3/4.

There must be some leftover, such as things I didn’t use at home, remember to be careful]

[understood. ]

But just after the discharge procedures were completed, the Mihua Municipal Building exploded.

At this time, Wang Ziyu just arrived in front of the Mihua Municipal Building.

Then I heard a "boom".

The front glass panel on the left side of the upper floor of the Mihua Municipal Building exploded directly! ! !

The entire front of the floor exploded! ! !

The heat wave of the explosion carried glass fragments and cement rubble and blew towards Wang Ziyu and others.

Wang Ziyu looked at the exploded fragments in his eyes, and his pupils shrank sharply.

Reminds me of some bad memories...

But...I can't remember it.

Wang Ziyu's eyes darkened.

This feeling is the most annoying...
