At the Moonshadow Island Police Station, the Twilight Police Department met with the old inspector and asked him to find out the file about Keiji Aso. As a result, there was a mess in the police station, and the old inspector couldn't reach it, so everyone could only help him find it.

Lin Si also arrived at the police station after returning from the clinic, and when Xiaolan saw him, she asked, "Lin Si, where did you just go?" Because everyone obviously set off together, but when they arrived at the police station, Lin Si disappeared, which made Xiaolan feel very puzzled.

Lin Si smiled: "My throat hurt a little after drinking fragrant rice wine last night, so I went to the clinic to find Dr. Asai to prescribe some medicine." Saying that, Lin Si also took out the medicine, and Xiaolan was convinced of it.

"Stop talking, you guys can help find it together." Kogoro shouted in the archives, and after shouting, Kogoro couldn't help but complain, "This kind of broken police station is really infuriating, people are messy, and things are messy." ”

So Lin Si also participated in the search for the file.

There is a lot of power in numbers, and a moment later a dusty file was found by everyone, and it was Conan who found it.

"Found it, it should be this file, the date on it is twelve years ago, and the name of Keiji Aso."

Everyone immediately leaned over, and Kogoro snatched the file bag and opened it, revealing a stack of A4 papers. In order to save time, he distributed the paper to everyone and asked them to check if there were any clues inside.

No one spoke, they were all carefully looking at the documents in their hands, and even Conan secretly took one.

"Huh?" Suddenly, Detective Takagi made a puzzled voice.

The Twilight Police Department hurriedly asked, "What's wrong, Takagi?" ”

"Is there a mistake here?" Takagi pointed to a passage on the document and said, "It says that Keiji Aso's son is frail and sickly...... Didn't Keiji Aso kill his wife and daughter? Why did another son pop up? ”

When everyone heard this, they were also puzzled, thinking that there was a mistake in the dossier.

However, the old local inspector slapped his head and shouted: "Ah! I remembered that Keiji Aso did have a son! ”

"What did you say?" Everyone was amazed.

Seeing that everyone was so surprised, the old inspector seemed to be very proud, and explained: "His son is frail and sick, and he happened to be hospitalized in Tokyo at the time of the crime, so he escaped by luck. Later, it seems that he was adopted by someone else. ”

"Why didn't you say it earlier?" The Twilight Police Department saw that he was still proud, and couldn't help but want to kick him away.

Conan couldn't wait to ask, "What's his son's name?" ”

The old inspector recalled: "Hmm...... It seems to be called Mashi? （Asou Seiji）”

Lin Si didn't pretend to be stupid, he seemed to suddenly react when he heard this, and said to everyone: "I remember the word Chengshi, not only can it be pronounced as Seiji, but also as Narumi, right?" ”

Hearing this, the picture of Dr. Asai introducing herself and the sentence she said suddenly appeared in Kolan Conan's mind - I am not a nurse, I am a doctor, and my name is Asai Narumi. （Asai Narumi）

"Hey...... It can't be, right? She's so cute......" Kogoro also realized this, but he couldn't accept it. How could such a cute person be a boy? The old man's heart hurts......

Lin Si made up a knife next to him: "There is a saying that if you are so cute, it must be a boy." ”

It's not that Lin Si wants to betray Aji's reality, in fact, making his identity public is part of the plan of the two.

The more I thought about it, the more terrifying I felt, "If Asai Narumi is really Asami, then this case is very likely that he is avenging his family!" No, we have to find out right away! ”

……

Everyone came to the clinic together, and Asai Narumi was sitting in the clinic, but there were no patients coming to seek medical treatment at this time.

When Kogoro saw such an elegant and dignified beauty, he still couldn't believe that she was a man. In fact, Chengshi has nothing to do with whether he is a man or a woman and Kogoro, but the problem is that Kogoro "fell in love at first sight" with her......

The beauty he fell in love with at first sight suddenly became a boy, except for Brother Gongba, who else could accept it?

"Mr. Mori, and the Tokyo Police Department, why are you all here?" Chengshi naturally stood up to greet everyone, with doubts on his face, so that everyone couldn't feel that something was wrong at all.

This guy is a man? Conan looked at Chengshi, also puzzled by his reasoning.

Lin Si saw that everyone was embarrassed to speak, so he took the initiative to take over the task of exposing the gender of Asai Chengshi. He stepped forward, stared at Narumi's face, and said, "We just went to the police station to check the file from twelve years ago, and it turned out that Keiji Aso originally had a son, whose name was Asami. The word Chengshi is the same as the Chengshi in your name, but the pronunciation is different. ”

Cheng Shi's face changed slightly, "You guys...... Suspect I'm a mahato? ”

No one spoke, which was a tacit acquiescence.

Cheng Shi laughed twice, "Your suspicions are completely unfounded, there are more people in the world who call Cheng Shi, is it possible that all of them are the sons of Keiji Aso?" "Although Chengshi intends to confess, he can't be too proactive, and he must show the psychology of being forced.

"Since you don't admit it, then I can only be rough." Saying that, Lin Si grabbed Chengshi's arm, and it seemed that there would be other actions next.

Chengshi asked in a panic: "You! What do you want? ”

"Of course, it's to confirm your gender, but the difference between men and women can be distinguished with the naked eye." Lin Si raised his other hand, spread his five fingers, and practiced opening and closing a few times in the air, and then it seemed that he was about to grasp something.

Xiaolan was already stupid, so she could only cover her mouth with her hands.

You have a lot of point, but if Dr. Asai is really a woman, wouldn't it be too much for you to do this...... Well, even if Dr. Asai is a man, you're going too far......

Asai Narumi seemed to be frightened, and hurriedly shouted, "Don't ...... Don't, I say, I'm a man! I'm Asashi! As soon as these words came out, Lin Si, who was about to put his hand down, stopped his hand in the air, and everyone stared at Cheng Shi.

The atmosphere seems to have frozen.

"You...... Really a man? Kogoro asked incredulously.

Chengshi hurriedly replied: "Yes...... Actually, I'm Ma Shengshi. ”

"Then why are you pretending to be a woman?" The Twilight Police Department questioned.

Chengshi put on a sad face at a 45-degree angle, looked at the sky and said: "My parents and sister died overnight, and it is rumored that my father set himself on fire after killing someone, but I don't believe it. So I came to the island to investigate, and I disguised myself as a woman to prevent others from knowing my true identity, because it is very likely that the person behind the scenes is on the island......"

Kogoro held back his tears and didn't let the tears fall, so cute, and sure enough, he was a boy.

"So, are you the one who wrote to my uncle? That's your crime teaser? Conan interjected.

Asa Sangshi looked dazed and asked rhetorically, "Faith?" Crime Notice? What is it? ”
