\"Why are there so many police cars outside, I will almost be discovered.\" Waiting in front of the door of apartment 504 at the scene of the crime, after Sato asked the apartment administrator to help open the door, Sato, who took off his velvet hat, looked at Xiaobai and said.

"I guess they're looking for you and Officer Takagi, after all, I haven't reported for so long.I guess Officer Twilight thinks you've been kidnapped by your uncle, so it's hot now.\" Standing in front of the door, Shiro replied to Sato while observing the inside.

"Well, I'm really sorry, I'm so grateful for helping me so much.\" The middle-aged man apologized to Sato.

"Ah, ah, I'll be upset if I catch the wrong person.Now let's hurry up and find out what clues there are.\" Sato replied with a smile as he walked into the apartment.

......

\"That's really the case.\" After Sato and Xiaobai put on their white gloves and checked some places such as the wardrobe, Sato lowered his head and said to himself.

\"The dark red curtains and sheets were found in the closet.\" Sato said as he looked at the bed and the curtains on the balcony not far away.

"And the calendar that should have been hanging next to the bed has also been put away.\" Xiaobai said as he handed the calendar to Sato.

"Even the December schedule is arranged.\" Sato said, looking at it.

"And the furniture has been moved.\" Xiaobai said as he looked around.

"Well, I always thought this was my home when I first came in.\" said the middle-aged uncle.

"It seems that this is indeed the case.\" Sato and Xiaobai glanced at each other and smiled.

"And then there's the matchbox found under the closet.\" Xiaobai said as he took out a matchbox from his pocket.

"Why didn't you take out something so important earlier.\" Sato said as he took the matchbox from Xiaobai's hand.

\"There is a marriage application in it, and the woman, Mami Muranishi, has signed and stamped it.\" Xiaobai said indifferently.

"But there is no man's name.\" Sato said, looking at the application.

"It's very simple, the man's name is the suspect.\" Xiaobai said as he looked at the balcony, where several pots of cacti were placed outside.

"But there's no evidence that it's him.\" Sato said with a frown.

\"That's right,**line,If it's Beichuan,,,**The line will definitely be able to be used as evidence.\" The middle-aged uncle suddenly thought of something and said.

\"That can't, because it's only your fingerprints on it, and even if a search of his home finds a ** thread missing, it doesn't mean anything.\" Sato shook his head and replied to the middle-aged uncle.

\"How could it be...\" After listening to Sato's answer, the middle-aged uncle was depressed.

\"Maybe the evidence has been found.\" In front of the balcony, Xiaobai's voice came.

\"Did you find anything?\" Sato and the middle-aged uncle hurriedly ran over and asked.

"It seems that the hostess here likes cacti very much.\" Xiaobai said, looking at some of the cacti placed on the balcony.

\"But what does that mean?\" Sato looked at Xiaobai.

\"At the time of the crime, I remember that it had rained in the morning, and these cacti were left outside.\" Shiro replied as he looked at Sato.

"All of this proves that someone has been here, but it's not direct evidence.\" Sato replied.

\"So, what about this.\" Xiaobai said as he walked towards the cactus on the very edge.

\"This... Only this pot of cacti has fallen off its needles.\" Sato also walked in, and after seeing it clearly, he shouted in surprise as he compared the rest of the cacti beside him.

"If I'm not mistaken, this is the best evidence.But the most important question is how to arrest him.If the suspect insists that he came the day before the crime, then this evidence will not be evidence.\" Xiaobai looked at Sato and said.

"So, the best thing to do is for him to say that he has never been here.\" Sato also looked at Xiaobai.

\"yes, that's the trouble.\" Sato nodded, and then made a thoughtful gesture.

\"Why are you here?\" While Sato was thinking, the voices of Takagi and the others came from the hall.

"Xiaobai, why are you here? and Officer Sato.\" Ayumi's voice also came.

"Well, I remembered that the key was dropped at the door, so I asked Xiaobai to help find it, but I didn't expect to find it, so we came first.\" Sato replied with a smile and a wave of his hand.

"Is that so?" Conan turned his head and squinted slightly at Xiaobai after glancing at the middle-aged uncle beside Sato.

"Don't talk about that.Takagi, get ready to capture the real culprit.\" Sato Masasei looked at Takagi.

\"The real prisoner?So you already know who the prisoner is?\" Takagi looked at Sato in surprise.

\"Well, with the help of this kid, everything is already known.\" Sato nodded, then looked at Xiaobai beside him.

"Aha...\" Xiaobai covered his mouth and yawned.

\"Really, we've gone to search for some clues.\" Yuan Tai said in a slightly depressed mood on the side.

\"yes, won't our efforts be in vain.\" Mitsuhiko and Ayumi are also a little depressed.

\"For your sake, when this case is over, my sister will invite you to dinner.\" Sato smiled at Yuan Tai and the others.

\"I want to eat eel rice.\" is worthy of Yuantai, it has been eel rice for 10,000 years.

...

\"You're moving very fast...\" When Yuan Tai and the others were talking about something to eat, Gray Yuan walked up to Xiaobai's side and smiled.

\"...\" Xiaobai didn't answer, but smiled, and then looked up at the sky.

As for Conan in the distance, he squinted at Xiaobai slightly, not knowing what he was thinking.

\"The expression of the middle-aged uncle just now is definitely not normal, that kind of surprised expression.\" Conan looked at Xiaobai and thought about the scene when Sato said that Xiaobai helped find the key.
