In the open-air restaurant, Maori Kogoro, in order to reason, makes everyone gather at the scene. Conan is ready for anesthesia, but the police can't find Sasayama mingko, and even Gao Cheng doesn't know where to go.

"Not yet? What are they doing? " Maori looked impatient, "forget it, it doesn't matter if you don't come. Anyway, I know who the killer is, among you people!"

Conan, who already knew everything, was speechless about Maori's boasting. After frowning around, he found Qiantian Cong and asked, "Mr. Qiantian, isn't miss Mingzi supposed to be with you?"

Maeda unnaturally thought of Gao Cheng, who was also absent, and said with a worried face, "I don't know. She answered the phone and went out before the police told us to come."

By the swimming pool of the hotel, the night wind is still blowing, whining.

Gao Cheng turned his back to Sasayama and said, "I always thought the killer was your fiance, former Tian Cong, but soon found out that he wasn't in your room at the time of the crime."

Sasayama mingko's face was pale. Although he had already guessed when he was called alone, he managed to squeeze out a smile and said, "yes, what's the problem?"

"I've asked the people in the hotel," Gao Cheng continued, "when it comes to this season, there is a strong wind called Princess wind at night, and the higher the wind goes, the stronger the wind will be. If a person falls off the balcony in the dark Duke's cloak, where will he fall?"

In Sasayama's trembling eyes, Gao Cheng's words became more and more clear in the wind: "yes, it will never fall on the bronze statue right below... In this way, we can understand why the murderer made Jiangyuan's room into a secret room, and the purpose is to make people think that the first scene of the crime was on the balcony, right?

"Because we all take it for granted that the anti-theft latch can't be fastened from the outside. Even if we find the secret room technique, we will think that the murderer did it after killing... But in fact, the murderer made the secret room first and then committed the crime from other places. The only possible one is room 1901, your room..."

Zuoshan silently lowered his head, with a stiff smile: "but..."

"Turn yourself in, miss Sasan," Gao Cheng said softly, turning back. "It's impossible to fall straight away from the airflow from other rooms... And the reason why Mr. Maeda took the risk to dress up as the Duke of the night is that he found that the prisoner was you, and he wanted to make an alibi for you, right? I'm afraid he's going to answer for you now... "

"Ah Cong that guy..." Zuo Shan grinned bitterly, tears gushed out, "Mr. Chenghu... No, detective Chenghu, I should have thought that this would be the result when I knew you and detective Maori were there at first..."

In the open-air restaurant, when Gao Cheng comes with Zuo Shan quietly, Conan has already made the final reasoning with the help of Maori Kogoro's identity.

"You are wrong! I'm the killer Maeda's voice spread far away, trying to explain, "I pushed that man down the stairs! I did it all, I did it all by myself

"Ah Cong..."

Sasayama mingko looked at the hoarse former Tian Cong, wiped his eyes and walked into the scene, saying: "it's unnecessary, a Cong, I killed the guy in Jiangyuan, and the detective in Chenghu has made it clear."

"Chenghu?"

Conan walked out from behind the sleepy Maori Kogoro and looked around in a hurry, but he didn't find Gao Cheng.

"Well? You mean the detective of the city A waitress who was asked by Conan looked into the hotel and said, "he just asked us for sugar water. Now it's probably over the kitchen... Ah, it's out there, right there!"

"Sugar water?"

Conan muddled for a moment, along the line of sight of the waitress to see, as expected, see Gao Cheng with a glass slowly coming.

At this time, Sasayama Mingzi has been handcuffed by the police and passed by. Maeda Cong was also escorted to the police car because of obstructing the investigation.

"I'll wait for you..." before Tian Cong got on the bus, he suddenly yelled to Zuo Shan in front of a police car, "Mingzi, I'll wait for you... Until you come back..."

Gao Cheng stands at the door of the hotel with Dongye Lake in his arms, watching two police cars leave with Qiantian and Zuoshan.

"What will happen to them in the future?"

"The judge should reduce the sentence according to his own discretion," Henggou said excitedly, turning to Gao Cheng. "However, it's really a detective from Chenghu. He cracked the case at the same time with detective Maori. It's a great honor to meet two famous detectives this time!"

Then Henggou stared at Dongye Lake: "this is the wooden knife. Can I touch it?"

"Er..."

Gao Cheng looks at Henggou excited, don't know what to say, this brother is really Henggou police officer?

At dawn the next day, all the police finished their investigation and left. The members of the tour group also checked out together.

In front of the counter in the hotel hall, Gao Chengzheng is struggling with the money, and Conan suddenly approaches.

"Hello, Chenghu, it was you who hurt Mr. Qiantian yesterday?" Conan asked curiously, "that's why you deliberately touched his arm in the interrogation room, and immediately checked Maeda's room..."

"What's the problem?" Gao Cheng turned around and said, "Mr. Maeda is too powerful, so I'm a little bit heavy. Even then, he escaped... I'll apologize to him next time."“ Hello, is that the point? " Conan held back his words and said, "Mr. Maeda was the champion of Japanese karate six years ago. Xiaolan couldn't even touch him... It seems that you are much more powerful than I thought."“ You think too much. What's the point of fighting an empty handed man with a weapon? " Gao Cheng shook his head and went on to discuss the room money with the counter staff. "..." Conan is speechless. Is there such a statement? Thinking of Xiaolan's violence in the past, he shook his head. He wanted to ask Gao Cheng about the case last night, but when he got to his mouth, he choked back. He just half opened his eyes and watched Gao Cheng and Maori Kogoro sweat for the room price“ In the end, there is no virus program at all, "Mr. Jincheng went to the counter with a smile." I thought I could teach a lesson to the guy who used computer viruses indiscriminately. " The old man went straight to Gao Cheng, suddenly took off his sunglasses and said, "detective Chenghu, is that Mr. jintianyi you? Are you interested in my commission? "“ Commission? " Gao Cheng and Maori Kogoro look at Jincheng at the same time“ Yes, "the old man said angrily," because that virus, the dark night Duke, destroyed the game software that I worked so hard to make four years ago and treated it like a son... By the way, what's its name? "“ It's a high school girl, Lord The servant Jing Jiang is helpless to remind a way“ Ah! Yes, yes, yes Ignoring people's strange eyes, the old man laughed. "In a word, it's the same with detective Maori. As long as you can find the real dark Duke, you can get 10 million commission fee!"“ Ten million commission fee. " Maori is a little envious, but it is impossible for him to find the owner of a virus program on the Internet. Gao Cheng smiles bitterly and shakes his head. It's because he knows the power of the dark Duke virus that he understands how difficult the entrustment is. The old man is not serious at all. He's just joking.
