After the simulation, the female characters in Detective Conan break down.

"understood……"

Conan's expression also looked very serious.

"Their car is coming this way."

At this moment, Kudo Yume quickly reminded her.

"Humph!!"

"This is a place that we spent the entire afternoon investigating."

"Moreover, this is the route they would inevitably take when they left."

"hidden!!"

At this moment, Hoshino Kiki squatted down slightly after finishing speaking.

The railing was a low wall made of mud, and three people could hide themselves by crouching down slightly.

At that moment, a white Toyota car was slowly approaching the building where the three people were.

Then, Conan took out four white, spherical objects, each about the size of a fingernail, from the plastic bag.

Hoshino quickly put on gloves and took out a small ball.

"Let's verify if the ball the doctor made is really useful?"

After Hoshino finished speaking, he stood up slightly, just enough to see the road below.

Then, Hoshinoki's pupils contracted slightly.

The silhouette of that white Toyota car became clearer and clearer.

"This is the moment!!"

Hoshino roared inwardly.

Then, swing your arm and flick your wrist slightly.

The white super glue ball slipped from his hand in an instant.

In an instant, the white Toyota passed beneath the building fog.

The small white ball landed perfectly on the roof of the white Toyota car.

Suddenly, the ball on the white car burst open.

A transparent, flowing mass splashed out from inside the small sphere.

Then, a mark appeared on the roof of the car.

Within this trace, a small, bean-shaped square appeared.

Moreover, the color blended in with the marks here, almost identical.

If you don't look closely, you won't even notice the small squares.

The small cube landed perfectly on top of the car and wasn't blown away by the wind despite the car's speed.

It's as if this little cube is stuck very firmly to the roof of the car.

"What's the situation now?"

Hoshino looked at Conan and said.

Then, Conan turned on his tracking glasses.

The lenses of the glasses displayed electronic images, much like a computer screen.

A few seconds later, Conan nodded.

"The transmitter has been installed very successfully."

"very good!!"

"The next step is to place the transmitters on the vehicles that have driven away."

Hoshinoki had a plan in mind and said excitedly.

A few minutes later, Hoshino placed all the transmitters he had brought in the departing vehicle.

Chapter 163 Negotiation

Soon, the four small dots moved rapidly across the tracking glasses.

At this moment, Conan looked very happy.

"Very good!!"

"By following them, we can quickly find many of that organization's strongholds."

"I must say, the doctor's invention is really amazing; it's perfect for espionage."

While joking around, Hoshino also genuinely admired the professor.

"I'm still a little worried about one thing: what if the tracking device is on their car and something happens?"

Why didn't any of those people go and check it out?

At this moment, Kudo Yume asked, full of doubt.

"The ball is relatively soft overall, and with some control over the force, the noise it makes is actually not very loud."

"And look, everyone..."

At that moment, Hoshino pointed to the ground.

"Some small stones were deliberately placed on the road, so that cars would make some noise when they drive by."

"As long as you time it right, you can throw the ball over the roof of their car."

"In this way, the noise above the roof of the vehicle was masked by the sound of the stones being crushed."

"Besides, the other party was also in a hurry to evade the police."

"Under these circumstances, I certainly wouldn't get out of the car to check it out."

"So this is ah……"

At this moment, Kudo Yume nodded in sudden realization.

While the two were talking, Conan had already contacted Dr. Agasa.

Conan said after putting down his phone.

"The doctor arrived to meet us very soon."

The explosion at Hirota Company occurred thirty minutes later.

In the conference room of the First Investigation Division of the Warning Hall.

Director Bai Ma was sitting at the head of the table in the conference room.

Moreover, his face was very serious and his gaze was very deep.

There was a telephone next to him.

This is a telephone for receiving emergency calls.

Under Director Hakuba's orders, the emergency call phone was temporarily moved to the First Investigation Division's conference room.

Director Hakuba was the only person in the First Investigation Division's meeting room.

Director Bai Ma's gaze kept drifting towards the telephone.

They seemed to be waiting for news.

Suddenly, the telephone rang.

The ringing of the telephone sounded particularly jarring in the quiet First Investigative Division's meeting room.

At this moment, Director Bai Ma's gaze clearly froze.

Without any hesitation, he quickly answered the phone.

"This is Superintendent Hakuba of the Metropolitan Police Department."

When Director Bai answered the phone, he introduced himself before the other party could speak.

The other party was silent for a short while.

Then, the deep voice of a middle-aged man was heard.

"It's quite a surprise to be able to speak directly with Inspector Hakuba of the Metropolitan Police Department. I'm a little flattered."

"No need for further words, let's communicate via mobile phone in five minutes."

Director Bai Ma spoke in a cool, clear voice.

The other party remained silent for a short while.

Then, the other party said something else.

"It seems that Director Bai Ma knows quite a lot."

"Okay, let's keep in touch by phone."

Next, Director Bai Ma gave his number to the other party.
