Looking at Yui's appearance, the corners of everyone's mouths twitched.

Yui, you really didn't think of anything?

Officer Twilight even thought of Yui's previous performance in the case of Emperor Moriya II, and couldn't help but ask, "Yui, are you really not expecting it?"

The only one glanced at Officer Twilight strangely, and said suspiciously, "Should I think of anything?"

"Uh......" Officer Twilight had nothing to say, so he could only cough dryly and said, "Forget it, Yui, if you think of something, you must say it in time!"

"Well, I will. The only face nodded indispensably.

Officer Twilight sighed slightly, touched his chin and said, "Hey, in this way, all the windows in the study are locked from the room, and it is impossible to get out of the room, so this door is the only entrance, and one of you who has the key to this room will never be able to get out of it." As he spoke, Officer Twilight turned to Tsujimura and asked, "Madam, there should be several keys in this study, right?"

"No, no," Tsujimura shook his head and said, "There are only two keys to the study. ”

"Only two?" Officer Twilight froze.

"Yes," said Tsujimura Koe, who reached out and took out a key with a key ring from the bag he was carrying, "one is this one in my hand, and the other is on my husband." ”

"Your husband?" said Officer Twilight, stunned.

"Well," said Tsujimura Kimie, "my husband usually used to keep it in his trouser pocket. ”

"So? I'll make sure. Officer Twilight turned and walked over to Mr. Tsujimura's body.

This one, there are autopsy personnel checking it.

Officer Twilight knelt down on one knee next to the corpse, put his hand into the corpse's trouser pocket, and after a little fumbling, Officer Twilight noticed that the trouser pocket was bulging, and it looked like something was really there.

Officer Twilight fumbled and pulled his pants pocket, only to see something strange.

I saw that inside the pants, there was a small pocket, and an oval-shaped object was showing its head, and with the movement of Officer Twilight, the thing slipped out directly, and fell to the ground with a "Kala".

It's the same key as the one in the hands of Tsujimura Gonge!

Everyone froze.

"How...... How is that possible?" shouted Officer Twilight in shock.

"What's wrong?" said Kogoro Maori.

As soon as Hattori Heiji wanted to speak, he heard Yui say, "Ahhhhhh

Secret, secret room killing?

The people in Tsujimura were stunned for a while.

Mori Kogoro, Conan, and Hattori Heiji couldn't help but smirk, and also, the legendary secret room murder...... That's the only thing to say!

Tsujimura Gonge was puzzled: "This Miss Maori, what do you mean by that? What is a secret room killing?"

Hattori Heiji explained: "This aunt, have you forgotten? When we came in, the door of this study was locked, that is to say, the murderer locked the door after committing the crime, and one of the keys to this study was on you who entered the study at the same time as us, and the other key was in the double pocket of your husband's trouser pocket, which formed a perfect impossible crime, that is, a secret room murder!!

"W-How is this possible?" muttered Mori Kogoro.

Heiji Hattori looked at Kogoro Maori's expression, and his eyes narrowed slightly.

Sure enough, this uncle's reasoning recently published in the newspaper is not his thing at all, it is Kudo Shinichi's! All the cases are solved by him, this mediocre uncle secretly contacted Kudo, asked for his help and solved the case, this time it is estimated that this time is the same, very good, who will solve this locked room murder incident first, let's see, Kudo Shinichi!

Hattori's eyes flashed with a glint of ambition.

But when I saw the girl with long brown hair next to me, I was stunned.

Fei Sang, do you know about this?

By the way, it is said that Fei Sang has also shown her talent for reasoning, but she has always said that she has no reasoning ability, does this mean that she is also aware of this?

Wei felt the gaze on his body, turned his head slightly sideways, raised his eyebrows and said, "Hattori-kun, is there something wrong?"

"Ah, it's okay!" Hattori Heiji hurriedly shook his head.

Forget it, I don't want to do this, let's crack this case before Kudo Shinichi!

Regardless of this uncle or Fei San, they should be able to get in touch with Kudo Shinichi, for my visit this time, Kudo Shinichi should understand what I mean!

Yes, that's it! Let's crack this secret room murder first!

Yui looked at Heiji Hattori, who was suddenly imposing, and didn't bother to care what this guy was thinking, and turned his head to look at Conan.

Conan's face was already very unsightly at this time, the sweat droplets on his cheeks were constantly sliding, and the flush that had been dispersed had returned to his cheeks.

Only frowning, is Conan's cold aggravated?

Conan struggled to catch his breath and keep his mind clear, but alas......

"Well, I'm so sad, I'm starting to have tinnitus now! It seems that I'd better solve this case as soon as possible and go back to sleep!"

Hattori Heiji turned to look at Officer Twilight and Mori Kogoro, who were discussing, and said, "What are you doing?"

Officer Twilight and Kogoro Mori both looked over.

Heiji Hattori said: "The time of the crime should be between half past three and four o'clock, in short, now we should find out as soon as possible the alibi of the person who may have committed the crime during this time, this is the most important thing, right?"

"Uh...... Yes, yes!" Officer Twilight laughed dryly.

Then, Officer Twilight turned his head and hugged Mori Kogoro's shoulder, leaned into his ear and said, "Hey, you can't lose to him!"

"Gah?" Mori Kogoro was stunned.

Officer Twilight lowered his voice and said, "Are you going to let this outsider hairy boy take the lead? I have pinned my hopes on you, Mr. Detective!"

"Uh...... Hey!" Mori Kogoro replied stunned.

Yui confirmed that Conan's expression was wrong, turned to look at Hattori Heiji, and just wanted to say something, he felt that Hattori Heiji's expression was not quite right, which made Yui open his mouth and close it again.

What does this black-skinned bastard want to do again?

Over there, Officer Twilight had already begun to inquire about everyone's alibi.

"So, Mr. Koike, the housekeeper, has been chatting with his neighbors at the gate between three and four o'clock in the afternoon, right?"

"Hey!" Koike Fumio nodded slightly uneasily.

Officer Twilight continued while taking notes, "So, Mr. Kizen and Miss Sachiko also arrived shortly before Mrs. Tsujimura went home, is that true?"

"Hey, that's true. Fumio Koike continued to nod.

Officer Twilight turned to look at Takazen Tsujimura and Sachiko Katsuragi and said, "So, where were you when Mr. Koike went to the entrance to welcome Mrs. Tsujimura home?"

Takazen Tsujimura said, "We went to my father's study, but the door of the study was locked, and he didn't answer, so we quickly went downstairs. ”

Sachiko Katsuragi continued, "After I went downstairs, I immediately met my mother in the entrance. ”

Officer Twilight nodded, turned his head to look at the old man next to him, Toshimitsu Tsujimura, and asked, "So, Mr. Toshimitsu came here, and it was after two o'clock?"

"Exactly. The old man nodded and said, "I finally came here, but Ah Dong was locked in the study, and Gongjiang went out again, so I really couldn't help it, so I kept watching TV in the living room next door to the study." ”

Officer Twilight took note of the call and asked, "So, when did Mrs. Tsujimura go out?"

"I went out an hour ago. Tsujimura replied.

Heiji Hattori listened from the side, and at this time there was already a preliminary conclusion, so the people closest to the victim at the time of the crime were the three people except Mr. Koike and Mrs. Tsujimura.

Officer Twilight turned to the CDs on the bookshelf next to him and exclaimed, "Wow, that's a lot of CDs here!"

"Yes," said Fumio Koike, "because my master has always liked to listen to classical music." ”

But when we first found the body, it was obviously an opera! Conan heard the word in a slight confusion, and thought in a daze, and just wanted to ask something, he heard Yui ask next to him, "Conan, are you really okay." ”

"Ah, I'm really fine, Sister Yui. Conan hurriedly laughed.

He swore that if he said he wasn't feeling well now, he would pull him straight back.

Wei frowned slightly, and just as he wanted to say something more, he heard Officer Twilight suddenly say, "Huh, madam, what ......is this photo?"

Yui and Conan instinctively looked up.

When I saw that photo, I was stunned.

Huh, who is the person in this picture, ......?

Conan wanted to see clearly, but found a sudden flower in front of him.

Damn, why can't you see clearly!

Conan instinctively began to rub his eyes.

Over there, Tsujimura looked very unhappy and said, "What are you looking at, these are all photos from twenty years ago!"

Lan was startled by Conan's movements and asked in a low voice, "Conan, what's wrong with you?"

"Ah, Sister Lan, I'm fine!" Conan continued to pretend as if nothing had happened.

Lan looked at Conan's smile, and although he was worried, he could only press it down.

"Officer, what should I do with the books on the desk?" a police officer in a suit ran over.

"Ah, just leave it at that!" Officer Twilight said casually.

Conan looked at the desk suspiciously, and muttered in his heart, "Yes, and those books, there is indeed a complete set of hardcover books in front of the deceased, it is like a large stack of books that have been removed from the shelves together." ”

Conan looked at the bookshelf next to him, which was clearly empty.

Just when Conan was confused, another trick policeman B ran over.

"Officer, this key on the victim is a bit weird. ”

"What?" Officer Twilight wondered.

Police officer B took out the key, and said while gesturing, "After this keyring is opened......"

"There's duct tape in there?" Officer Twilight had seen as well.

Hattori Heiji had already leaned over and looked at it curiously.

What is this? There's a small gap in the middle of the keyring.

"Let's ...... Let me see it too!" Conan staggered a little, but was hugged by Lan.

"Conan, what's wrong with you?" Lan asked hurriedly.

Yui's hand had already reached out to Conan's forehead, and he was directly startled by the hot temperature under his hand, and his face sank, "He's having a high fever!"

Boom! Conan's body shook violently! Instinctively covered his chest, his little face white.

Lan was taken aback, "Conan!"

Wei's face was also completely gloomy, and he said, "Conan's body is not quite right, Dad, Officer Twilight, let's find a room for Conan to rest! ”

"Uh...... "Officer Twilight was stunned.

Hattori Heiji was so made by Yui's cold eyes that he couldn't help but swallow his saliva, don't, don't be kidding, I was really kind just now!

Maori Kogoro looked down at Conan's ugly face, nodded and said, "It's okay, Yui, Lan, you two take care of him!"

"Hmm!" the Maori sisters nodded at the same time.

Lan stood up directly with Conan in his arms, ready to find a room to rest.

Conan struggled, "Lan ...... Sister, I'm fine!"

Lan didn't pay attention to the little bamboo horse who came up with his cow strength, but said expressionlessly: "When you are well, I will let you eat raisin porridge with grape pie for a month!"

Listening to Yui's threat, Conan couldn't help but smile bitterly.

The Maori sisters took Conan out of the field and went to find a place to rest.

In the eyes of their sisters, this kind of case is enough to have Mori Kogoro and Hattori Heiji, and as for the schoolboy detective who is obviously not very peaceful, it is better to take a smoking.

The Maori sisters found an empty room and carried Conan inside.

Lan carefully put Conan on the bed and asked worriedly, "Conan, what's wrong with you?" Sister, is it better for me to find a doctor for him?"

"Lan, it's okay with me, it's much better now. Conan waved weakly at Lan.

Wei lowered his face, reached out and pressed on Conan's wrist, and said in a low voice: "I'm just rude to Chinese medicine, Conan, you haven't eaten anything strange today except for that white dry wine, right? ”

Conan said slightly dazed: "I didn't, didn't I drink some white dry wine brought by that black guy today?" Ah~~~~"

Conan screamed.

"Conan!!" Lan exclaimed, she was frightened by the situation in front of her.

Yui's pupils also dilated suddenly, and in their sight, they saw that Conan's body was constantly dilating, expanding, as if he had grown up!!

Wait, grow up???

The only surprise is that he hurriedly reached out to take off Conan's clothes, damn it, if Conan was really growing up, such a small dress would suffocate him!

Conan only cared about the pain in his body, he didn't have the strength at all, and he didn't care about resisting Yui's movements, he only felt that he had almost ripped his clothes in three or two clicks, and then a sheet was covered, and then the severe pain in his body increased violently, and then worsened!!

"Sister, sister! Ke ...... New !!"

Lan was just about to say something, but he was stunned by the scene in front of him.

The original toddler's body grew up in a very short period of a few seconds of practice, and it became a sixteen-year-old boy's body!

"Sister, this ...... Conan...... New ......"

Although he had long known that the six-year-old boy in front of him was his childhood sweetheart, but seeing him grow from six to sixteen years old, Lan was inevitably stunned.

"Hah...... Ha ...... "Shinichi finally took a breath at this time, and looked at himself in disbelief as he turned into a teenager's body again, and looked up at Lan who was looking at him blankly in a slight daze, and opened the cabinet next to him, not knowing what he was rummaging through.
