A concise summary not only allows the expressor to show his core ideas, but also allows the listener to fall into the confusion of reading comprehension.

Just when Conan was confused, Hattori Heiji also ended the call with Officer Otaki.

"The blood residue and wound marks have been identified. It seems that the same person who killed Sakura and attacked me!"

A sentence made a detective deviate from his thoughts in an instant. He immediately stopped worrying about whether Officer Shiragou was dead or alive, but subconsciously muttered: "But why did he throw the murder weapon by the river?"

Hattori Heiji guessed: "Is it possible? It is because the murderer lives near Yamanoji. He is worried that after taking away the weapon, he will be directly searched by the police."

"So, we are still very suspicious."

Noting the eyes of several people, Chigasuzu explained: "Because Yamanoji is on Hexao Road, from there, it is very close to the tea house, Mr. Mizuo's dojo, or Mr. Nishijo's bookstore..."

"Huh?" Hattori Heiji was stunned, "So it's the hexagonal road there..."

"Yes, Marutake Yiji, Otsuki, Sister Hexao..." Chigaruo hummed the nursery rhyme softly, "So Yamanoji is on the sixth road."

Sakura, ball, nursery rhyme, and the scene of the little girl reappears...

Seeing a certain black skin in a daze, Conan coughed and asked, "Sister Chiheling, what did you sing just now?"

"We all call it the pizza song, which is a minor tune composed of the names of Kyoto's roads from north to south..." Chiga Ling said, and hummed the nursery rhyme in full, "When we were young, we used it to remember the names of these roads..."

When Hattori Heiji heard this, he couldn't help asking, "So... are you from Kyoto too?"

"Yes." Chiga Ling smiled.

"How old are you?" Hattori Heiji asked hurriedly.

"19 years old." Chiga Ling said.

Ten... Nineteen years old...

Hattori Heiji's pupils contracted and he subconsciously wanted to take out the pencil drawing to confirm, but when he thought of the code on the other side of the paper, he stopped this action again.

No... Miss Chigasuke cannot be seen. After Sakura was killed, the murderer took the secret message from him. If it weren't for simply concealing his identity, it might have hurt Miss Chigasuke.

Hattori Heiji kept radiating his thoughts, which led to his semi-distracted state along the way.

Ye Gengyi watched coldly and guessed secretly.

Could it be that kind of bloody plot of first love being a murderer?

However, looking at Chigasuzu, he doesn't seem to have the ability to hospitalize Hattori Heiji...

Until we reached the intersection of Yuchi Road, we said goodbye to Qianheling.

Conan finally couldn't help asking: "Brother Heiji, you are too boring, and you can't be sure if she is..."

"It must be true!" Hattori Heiji interrupted, "She is from Kyoto, she is two years older than me, and she can sing that song..."

Conan had no choice but to say, "But, kids in Kyoto can sing that song, right?"

"I finally saw her..."

Hattori Heiji was still immersed in his own world and no longer avoided anything at this time. He took out the picture and wanted to recall it in a small way.

You guy is so helpless... Conan raised his head and gave him a blank look. Suddenly, after seeing a few lines passing through the paper, his expression gradually became serious.

This is......

"Show me!"

Conan excitedly grabbed the secret message, held it high towards the light source for a long time, and said, "I think...I know what this secret message means!"

"What?! Worker...ah, no," Hattori Heiji almost bit his tongue, "You unzipped the code?"

"Well, this should refer to the road name of Kyoto, thanks to the painting drawn by Gengqian brother on the back."

Conan spread the secret message directly, pointed to the overlapping positions of lines, and said, "Look, does this lattice window look like a crisscrossing road!"

"So that's it. Then the fifth floor of this tower refers to five roads, the fourth floor is four roads, and the middle between the third and second floors is where we are now..."

Hattori Heiji said this and scratched his head and said, "By the way, how did that song come about..."

"Acorns go away, roll, plop, fall into the pool~ It's so bad~" Conan immediately hummed, trying to find the tone.

Hattori Heiji's expression froze: "..."

Is it still time to withdraw that question now?

"Shut up, stop singing!" Ye Geng frowned, washed his ears with hidden headphones, and interrupted coldly: "Just know it represents Yuchi Road."

Conan: "..."

Why are you so responsive...

"It seems we need a map of Kyoto." Hattori Heiji quickly changed the topic.

"Yeah, let's go."

Ye Gengyi directly retrieved the secret message from a primary school student, and then left without looking back.

Conan: "..."

Illusion, this must be my own illusion...

......

"The song "Shunyu Ogawa" contains violets, which should refer to Ogawa Road. Tengu comes from Utuntu and refers to Karasuma Road. As for Mount Fuji, there is a word "Fu", so it refers to Fuxiao Road."

Hattori Heiji held the ink pen and while reasoning, he drew a horizontal line on the five roads on the map. "Loach is related to Yanagawa pot, which refers to Yanagawabata Road... But what does chicken mean?"

"Yes, there seems to be no similar signs on the four roads..."

Conan mumbled, his eyes turned, and noticed that Ye Gengyi was silent and his mind moved.

Hey? Isn't the first brother good at solving the secret codes in this regard?...

Right!

The code refers to the road in Kyoto, so I discovered it first!

You must seize it. This may be a rare opportunity to surpass the top player in reasoning!

A detective's brain is running at high speed.

As a result, Hattori Heiji, who had a headache, asked, "Brother Geng, do you have any ideas?"

"Well, but it may be a bit far-fetched." Ye Geng said, "To apply Feng Shui theory, if you want the group to work hard again, you usually place a rooster in the hall of your home or the west side of the office."

West side?

Hattori Heiji thought when he heard this and analyzed, "Will this chicken refer to Xidongyuan Road?"

Conan: "..."

Is it rare to say that one would be better than the top player in reasoning?

"It's really difficult to have knowledge about Feng Shui..."

Hattori Heiji sighed, his eyes fell on the red cicada. As soon as he was about to speak, Conan said first: "There is a kind of cicada called oil cicada, so it refers to oil path."

Hattori Heiji looked at him helplessly, "The goldfish should be from 'the feed of goldfish is wheat bran', which must be the glutinous rice road."

"Then connect the same color violet and Mount Fuji, chickens and loaches, cicadas and goldfish, Tengu and Tengu..."

Conan actively spoke and wrote the word "king" on the map with an oily pen.

"King? Why is it the King?" Hattori Heiji was still a little confused.

"There is one point left! That's it."

In order to solve the mystery before the two of them, Conan did not think too carefully this time, and directly moved the ink traces that were originally on the right side of the four and five elements of the map to the bottom.

Forcibly turned the original "王" into "jade".
