Because the angle between the hour hand and twelve o'clock on the surface of the northern hemisphere is the direction of true south. As long as true south is determined, other directions can be determined one by one."

"I see, it's really simple!" Mao Lilan praised as if he had learned a new skill.

Conan ignored Aoki Song and others behind him, but looked at the environment outside the glass window with concern.

[Due south is the direction of one o'clock, southwest is the direction of half past two, and so on...]

Conan held up his watch with his left hand and compared it with the buildings outside. When he compared a building, the corners of his mouth raised.

[So that’s it, I solved the secret code on Kaitou Kidd’s notice letter]

However, when he thought of what Aoki Song said just now, Conan's joy was slightly reduced. Hearing Aoki Song's familiar words, he had indeed solved the secret code a long time ago, and he lost again this time.

Seeing Conan put down his hand, Mao Lilan quickly asked: "Conan, have you figured out the password?"

"I figured it out. Brother Aoki's reasoning is correct. It is indeed the rooftop of the Cupido Hotel." Conan replied.

After hearing this, Suzuki Sonoko became interested and immediately asked: "How did you solve it?"

Conan did not answer directly, but looked to Aoki Song aside and asked: "Brother Aoki, can I tell you?"

After hearing this, Aoki Song looked at the new name Kahori and asked with a smile: "Kahori, have you solved it?"

Niina Kaholi showed a bright smile, "Thanks to little brother Conan, I had no clue at first, but after Conan acted like that and you said those words, I suddenly figured it out."

After saying his new name, Kahori blinked, "The key to cracking the problem is the 'radio wave', right?"

Aokimatsu and Conan's eyes widened a little when they heard this. They were obviously a little surprised that Shinname Kahori could accurately tell the key.

In fact, Aoki Matsu was okay, he knew that Niina Kahori was talented in this area.

But Conan was a little stimulated. What happened today? Why are neither of them weaker than him?

Is it possible that I used to sit back and watch the sky, and those news reports that I was touted by others in the past, in the eyes of truly capable people, did I feel that I was a clown?

"It seems I was right." Niina Kahoori looked at the reactions of Aokimatsu and Conan and said happily.

Aoki Song heard this and said with a smile: "Yes, the key is the radio wave. I know you can definitely decipher this code."

"It's still difficult. Most people don't think about 'radio waves.'" After saying his new name, Kaori looked at Conan and said, "I can solve it because of Conan. Conan is really smart. He deserves to be your child, Mr. Mori.

Very well taught.”

"Where." Mouri Kogoro replied subconsciously, and then laughed.

Conan immediately went online.

It's not because Kogoro Mouri taught him that he is so good, but he is so good himself.
