Ke Xue: I picked up a bottle of sherry at the beginning.

At this time, a police officer walked over and said that they were going to investigate everyone and called Shiori out. Conan took the opportunity to sneak up to Sakazaki and asked: "Mr. Sakazaki, what did Sister Shiori say just now..."

Sakazaki quickly waved his hands, forcing a smile on his face: "Ah, that, it's nothing, she... misunderstood."

Seeing him like this, Conan stopped asking and changed the subject: "I have something to ask you. Where did you find the letter today?"

"Ah... the letter. It's on the ground at the entrance. There's no envelope, just a piece of paper."

Conan thanked him and ran behind the gate to observe carefully. After some hard thinking, a smile gradually appeared on his face.

"That's the murderer! Although I haven't found any evidence to prove my theory yet. But it won't be long, I will definitely find you out!"

In the music hall, the principal and his colleagues were still under investigation. Conan, pardoned because of his young age, dashed about searching for evidence. He then went to the window and saw something glittering in the bushes outside. Conan quickly ran out, ducked into the bushes, and parted the leaves to see an empty cat food can. Conan remembered Michiko's words about how the stray cats living in the school were fed, and this can was brand new, as if it had just been used by a cat.

Just as he was thinking, he heard voices outside the bushes, and Conan hurried out. It turned out that Mrs. Hasumi, Michiko and others had also come out. Mrs. Hasumi was holding a can of cat food in her hand, and said sadly: "I bought this at the supermarket to treat Heibei... Now it seems that I don't have time to feed it..."

She opened the can with a snap and placed it on the ground. "It's a rare visit for me, so I'll just leave it here. I hope it can eat it. I hope that thanks to it, the murderer can be caught..."

The principal, Michiko, and Shiori all stood quietly aside, looking at her with great sympathy. Suddenly, a cat's meow came from behind everyone. Conan looked over and saw a chubby little black cat with an earring on its right ear running towards the cat food can.

Conan was pleasantly surprised: Isn't this Sakura? It's really like "after searching high and low for something, it comes to him without any effort"! At the same time, he felt ashamed. Maybe his friends were working hard to find it, but he had forgotten about it long ago.

Mrs. Lian Jian caressed the little black cat lovingly and said, "Little guy, are you hungry too? Well, I'll give you some of this..." As she spoke, she poured out half of the cat food and placed it in front of the little black cat. The little black cat didn't hesitate and started to eat it voraciously.

Conan felt a surge of excitement.

"Okay, everything is ready! Now it's just a matter of how to make the truth known to the world!"

Conan quickly thought of a solution, which was to ask Qin Xuan for help.

Conan wishes Shiraizumi, Ran, and Eri a happy life together

Conan greeted Baiquan Yi, and Baiquan Yi leaned over and listened attentively.

It turns out that Conan has discovered the truth, but Shiraizumi Mashi is busy hanging out with Xiaolan and Eri, and his mind is not on the case at all.

"I'm very sorry for taking up so much of your time today. If you need anything in the future, I hope you'll cooperate. Thank you for your understanding! You can go home now..."

In the music hall, Inspector Megure and his subordinates had packed up and were ready to leave.

"Inspector Megure, please wait a moment!"

Everyone looked in shock and saw Bai Quanyi appear at the gate: "Please don't leave yet, I've figured it out! The murderer is among you!"

This statement caused an uproar in the music hall. Everyone's faces suddenly changed, and they began to talk.

The principal and the sheriff asked in unison: "Who is it?"

"The person who sent several threatening letters and used an ingenious device to poison Mr. Hasumi," Bai Quanyi pointed at the crowd, "is you—Madam Hasumi!"

Everyone was shocked, and Michiko and Shiori even screamed.

Madam Lian Jian was startled, but quickly calmed down: "What a joke! How could it be me?

Michiko thought about it and said, "That's right. The murderer set up the trap when we were out for dinner. Mrs. Hasumi couldn't have done that."

"What if the mechanism was not set up during the meal, but was set up before?" Bai Quanyi said calmly according to Conan's explanation just now, with a confident look on his face.

Madam Lianjian laughed and said, "That's even less likely to be me. This is my first time here!"

The principal nodded and said, "That's right, she asked Renjian-kun to be her tour guide when she came."

Bai Quanyi said sarcastically, "Really? That's strange. I feel like you've been here before—because when I was shopping at the supermarket this day, you walked right up to the cat food shelf without hesitation. This can't be your first time here…"

Mrs. Lian Jian was surprised, and then said: "That's because the merchandise in every supermarket is similar!"

"Yeah, this doesn't prove anything." Inspector Megure also said, touching his chin.

Seeing Inspector Megure also speaking up for her, Mrs. Hasumi calmed down and asked Shiraizumi, "You said it was the mechanism you made before, so why was everyone fine during the rehearsal? My husband, Mr. Hasumi, also lowered his chair at that time, so why was he fine?"

"Because the chair is equipped with a safety device!" Bai Quanyi explained.

"Safety device?" Everyone was stunned.

"And it's a very simple device," Baiquanyi walked over to the chair that killed Mr. Hasumi and pointed at the protruding nail. "This nail is the safety device!"

Inspector Megure hurried over and looked at the inconspicuous nail, puzzled.

"Look, there are several coils of string wrapped around the nail. During Mr. Hasumi's rehearsal, there was no string wrapped around the nail." Shiraizumi released the string from the nail, and the taut string suddenly loosened. Even if the chair was lowered to its lowest position, the string would not reach the point of tension, so the needle tip would not be exposed. By wrapping the silk around the nail, it was actually shortening its length."

"After Mr. Renjian finished playing, you pretended to play the piano, sat on the chair, and wrapped the rope around the nail. Needless to say, everyone knows what happened after that." Xiaolan said confidently and orderly.

Mrs. Hasumi sneered: "Haha, if you say so, aren't they the more suspicious? Apart from my husband, the last two people sitting on this chair were them!" As she said that, she looked proudly at Shiori and Michiko next to her, and her cold eyes gave the two girls goose bumps all over their bodies.

Conan, who was standing outside the window, sneered back at Xiaolan through the sound generator he had placed on her: "That's impossible. There aren't any fingerprints on this mechanism. Besides the lady who was wearing gloves at the time, who else could have rolled up the silk without leaving fingerprints?"

"Ah!" Madam Lian Jian's face suddenly changed and she was speechless.

Sakazaki looked at her with horror: "So, is it really you?"

Mrs. Hasumi calmed down and asked Baiquanyi, "How do you explain that letter? Someone left it here when we went out to eat—Mr. Sakazaki, right?"

Sakazaki nodded and said, "Ah...yes! When I returned to the music hall after lunch, the letter was on the floor. Mrs. Hasumi was in the supermarket with everyone at the time! And when we left the music hall before lunch, I was the last one to leave, so I didn't see any letter."

Upon hearing this testimony in her favor, Lady Lianjian became proud again and asked provocatively, "So? When did I put the letter in?"

"Before lunch!" Bai Quanyi smiled, stared at Mrs. Lianjian, and spoke word by word.

Sakazaki was puzzled: "How is that possible? The letter was clearly put in during lunch time!"

"To be precise, the letter fell to the ground during lunch!" Shiraizumi said. Everyone looked at each other in confusion, and the more they listened, the more mysterious it seemed. Conan sneaked in while no one was paying attention, blending in with the crowd. Then he stood up, holding a spray gun in his right hand and a piece of white paper in his left.

"Conan, please explain the tricks here to everyone!" Baiquan Yi said to Conan as agreed.

"Okay, Brother Baiquanyi!" Conan nodded innocently.

"Everyone, look carefully!" Conan walked to the back of the concert hall's gate, wet the white paper with a sprayer, and then gently pressed the white paper against the back of the gate. The white paper was firmly stuck to the back of the gate.

Then, Conan made a gesture of closing a door: "Look, the person closing the door cannot see the back of the door. And this piece of paper is just wet by water. Once it dries, it will peel off and fall to the ground! The crooked anonymous letter I received today is proof of this ingenious technique!"

The principal glanced at the letter in the plastic bag and nodded in agreement. Shiraizumi turned to Mrs. Hasumi and said with a smile, "Well, ma'am, could you please let us see what's in your bag? There should be a water sprayer in there, right?"

"Indeed, there is!" Mrs. Lianjian said bluntly, seemingly unhurried. "But this is what I use to fix my hair. Just based on this, you can conclude that I am the murderer? You are indeed very clever, little girl, but what you said just now was just your imagination. Do you have any solid evidence?"

At this time, Conan slipped under the window again like a loach, so Baiquanyi said what Conan had said to him before: "I really don't have the exact evidence you want, but there is one thing I want to ask you... Mrs. Hasumi, you said you wanted to meet Heibei, right?"

"Yes, so what?" Mrs. Lian Jian looked puzzled.

Bai Quanyi continued, "Just now outside the music hall, you also saw a black cat, right?"

"Oh, yes, what's the matter? Can this cat prove that I am the murderer?"

Bai Quanyi smiled. "That's right. Even if it pointed out your true identity as the murderer! Since you met it, why didn't you say 'This is Hei Bei' at the time?"

Mrs. Lianjian was completely confused, and so was everyone else.

Bai Quanyi raised the corner of his mouth and said, "Anyone who saw the little black cat for the first time would probably think it was Hei Bei, but you said, 'I'll give you some,' and gave half of the cat food you originally intended for Hei Bei to the little black cat."

Mrs. Hasumi was stunned, and the principal, Shiori and Michiko also understood a little.

"That means you knew the cat wasn't Heibei, meaning you knew what Heibei looked like." Bai Quanyi paused and said, "There's an empty can of cat food in the bushes. That must have been you, right? You've been here many times to build the mechanism on the chair. To set up such a sophisticated mechanism, you'd have to do a thorough investigation beforehand. It was during that time that you met Heibei, and to prevent cat lovers from bothering you, you started feeding it. I've actually asked the police to investigate that can. There's your fingerprint on it, Mrs. Hasumi... You only bought one can of cat food at the supermarket today. So, when did you open that can? You seemed to say it was your first time here, right? You've actually been here many times, but you lied and said you only came once. Why is that? Can you give us a convincing explanation..."

Bai Quanyi's words hit Mrs. Renjian like a barrage of cannonballs.

"Enough!" Madam Lianjian suddenly yelled hysterically. She stepped back repeatedly, her delicate body trembling, looking extremely sad, with crystal tears welling up in her eyes.

"Lanjian is a world-class pianist, but being the wife of a world-class pianist isn't a happy thing. He may look like a gentleman who loves me, but he's actually quite the philanderer... Too lonely, I started gambling... So I got into a huge debt, and to pay it off, I wanted to use his insurance money... I thought this was my last gamble, but I lost anyway..." At this point, she laughed nervously, "Alas, Heibei, I took such good care of you, but it seems you're not such a lucky cat after all!"

"I don't think so."

After Shiraizumi finished speaking, Conan squatted down. At his feet were two adorable black cats: Kuroi and Sakura. He was thinking about finally getting the bottle cap figurines his friends had been dreaming of.

The police took Mrs. Hasumi away, and the concert was cancelled due to Mr. Hasumi's death.

Xiaolan and Eri hugged Shiraizumi Yi with admiration and praised him for being so smart.

In response, Shiraizumi thanked Conan: "Thank you. Helped me to bring Xiaolan and Eri closer together."

Conan's head turned green, and he said with a wry smile: "You're welcome, Brother Shirazumi. I wish you, Sister Xiaolan, and Aunt Eri happiness!"

Bai Quanyi was invited to be a model

Hanaoka Art Collection Agency wanted to invite Izumi Masu to collaborate with them to publish a picture book. The agency had business dealings with Dr. Agasa, so they asked Dr. Agasa for help, and Dr. Agasa asked Ai for help.

So, Xiao Ai invited Quan Yi.

Izumi and Ai have been at Hanaoka's office for a long time, but Mr. Hanaoka has not shown up yet.

Mr. Matsushita, a clerk at the Hanaoka Office, had to accompany him temporarily.

Let me be a model? Bai Quanyi was not interested in being a model, but since it was Xiao Ai who asked.

Mr. Matsushita explained: Mr. Hanaoka is a painter and also the general manager of our company. We invited you here today because we plan to invite you to be a model in our art collection.

puff--

As soon as they said this, they heard Xiao Ai's laughter from behind.

Mr. Matsushita asked in confusion: What's wrong with you?

Xiao Ai, who had finally managed to stop laughing, said, "Izumi-kun, I thought you were going to invite him to write a preface for your art collection, or perhaps do an interview at the end, but you actually invited him to be a model. Bai Xingxing can debut as a model now. It seems your beauty has been recognized by everyone."

Quan Yi's head was full of black lines. He crossed his arms, curled his lips and asked: So - may I ask where is the great painter Mr. Huagang now?

The teacher hasn't arrived at the company yet. I guess he's still sleeping. Speaking of this admirable teacher, Mr. Matsushita was very respectful.

In an apartment building across from the office, pink light filled the small bedroom tightly covered by curtains.

The beautiful Chouno was kneeling in front of the bed, smiling secretly while painting a purple butterfly pattern on the face of the still sleeping Hanaoka.

Dieye was wearing a light blue suspender nightgown, her exposed shoulders looking incredibly white under the light. Behind a pair of wide-rimmed glasses, her large, watery eyes twinkled, her elegance radiating a certain spirituality.

Chono's movement woke up Hanaoka who was lying on the bed. He sat up and asked, "What are you doing?"

You're awake! Choye said gently.

Hanaoka wiped his face. What is this? Paint?

It's nail polish, the color is beautiful! It just came out today!

"Oh, this is unbearable!" Hanaoka rubbed the nail polish off his face with his hands, muttering softly.

Why don’t you get ready? You have an appointment with someone at 5 o’clock today, right? Have you forgotten? Dieye said as he opened the curtains.

With the famous criminal Bai Quanyi.

Oh, no!

Hurry up, I have put on your pants and socks for you... Choye said as he made the bed.

Don’t play such a prank! Hanaoka warned, “If my wife finds out, it will be over.”

I wiped it just because she found out! Dieye playfully acted like a spoiled brat, "This way you can get a divorce smoothly, and we can be together openly!" Dieye held his chin with his hand and yearned for it again.

Pah! A hard slap shattered Dieye's fantasy.

Aa ...

Hanaoka said fiercely, "I've told you long ago that this is purely business between us. It's because of this that you can draw the illustrations you love and live in such a luxurious apartment!" Then, Hanaoka dressed and left.

I'll tell everyone! Chou Ye covered his face and shouted at Hanaoka's back at the top of his lungs.

"Hmph, my wife has already found out and acquiesced!" Hanaoka looked indifferent, even a little gloating.

After hearing this, Dieye calmed down. After thinking for a moment, she said desperately: Humph, it’s not about us, it’s about the painting.

Ah——! Hanaoka was stunned, his eyes wide open.

Do you want me to announce that 60% of your current paintings are my work? Once everyone knows the truth, your status and reputation will plummet, and no one will buy your paintings anymore. Choye folded his arms across his chest and slowly put on his contact lenses.

She knew that this was a fatal handle for Hanaoka, and she was fully confident that she could manipulate it and she would be the ultimate winner in this contest.

Hanaoka, who was following behind her, asked nonchalantly: But who would believe the words of a novice illustrator?

Oh! Don’t you know that every time I finish a painting, I put a special mark on it!

You—what did you say? Hanaoka couldn't believe his ears. He brought his own art book and flipped through it anxiously.

Look carefully, under your signature on each of my paintings.

This is--?

My signature! Even though my style is different, I still have this mark on my own work. Thanks to the increased workload you've given me, my original works are gradually becoming famous! Dieye blinked at the mirror with a smug smile, adjusting his contact lenses. "I also stayed up all night to finish a painting today. 187. I'll have it delivered to the publisher later." Dieye opened his lipstick again, his tone suddenly becoming vicious. "It seems you'll never be able to escape from my control in this life!"

Hanaoka's hands were shaking as he supported himself on the table. Thinking of all the bad things that had happened in the past for so long and the consequences of this incident, his patience had reached its limit. After hearing Choeno's last words, he lost his mind and grabbed a glass ashtray on the table and smashed it on Choeno's head.

……

In Hanaoka's office, Izumi was getting impatient waiting. He knocked on the table. "It's already half past five. Hasn't Mr. Hanaoka arrived yet? With all due respect, my time is very precious."
