Detective Conan: The System Takes Me to Zero's World

Only then did Hibiki realize her mistake. She looked around and saw the curious looks from everyone. She couldn't help but feel a little embarrassed. She coughed lightly and said, "Is there any clear evidence? Well, you are..."

Masumi Sera introduced herself, "I am a classmate of your daughter, Ms. Xiaolan. My name is Masumi Sera."

She took out her phone from her bosom, tapped the screen a few times, found the code image, and then flipped the screen to show it to Eri Kisaki. "This is the code the criminal sent to the hotel during the first bombing. I found it by chance on the Internet this morning."

Hibiki took the phone and looked at the code on the screen. She frowned slightly, as if she was thinking about something.

Sera Masumi didn't stop and continued, "Then it was this... I found the secret code sent by the criminal in the room of the man who lived next to me."

She reached into her bosom again, took out another piece of code paper, and handed it to Hibiki Eri, "Is it exactly the same?"

Hibiki Eri carefully compared the two codes, confusion flashing in her eyes: "Indeed, they have never been announced to the public."

Kudo Yuki smiled and said, "Actually, Conan and Masumi have something to ask Lawyer Hime for help."

After hearing this, Kisaki Eri looked at Kudo Yuki thoughtfully and returned the phone to Sera Masumi. She leaned forward and looked down at Conan. Her eyes were full of scrutiny. "And then? What do you want to ask of me?"

Conan looked up and pointed in the direction of the front desk. "In order to allow them to contact the hotel as soon as possible after receiving a similar code, the police also sent the code for the second explosion to this hotel, but they refused to show it to us."

He looked at Kisaki Eri with eager eyes, hoping that she would agree to help.

Kisaki Eri approached with a suspicious look, and Conan's words, which were originally quite smooth, suddenly became intermittent: "So, Aunt Eri, as long as you mention the name of the famous detective Maori Kogoro..."

Hibiki Eri's expression changed, and a hint of displeasure flashed in her eyes: "I see, you want me to come forward and say that my husband Kogoro asked me to do this, so that you can investigate this incident, right?"

Conan nodded repeatedly, his eyes full of earnestness.

Kisaki Eri looked at Conan with a speechless look, raised her eyebrows, and uttered three words: "I, won't, do it!"

Kudo Yuki still had a smile on her face, as if everything was within her expectations. She turned to look at Sera Masumi: "Oh, Masumi, how about you give it a try?"

Masumi Sera smiled and thought about how to convince Eri Kisaki.

Hibiki stood up and muttered indignantly, "Why do I have to mention the name of that mustache guy to curry favor with the hotel so that they can provide the code? Can't I just call the police?"

After hearing this, Sera Masumi quickly smiled and waved her hands: "No, the second bombing happened because the criminal knew about it and the hotel called the police, so..."

She didn't continue talking, and Hibiki Eri understood the meaning. If she rashly called the police again, it would likely lead to the criminal's extreme behavior, resulting in more serious consequences.

Kisaki Eri frowned slightly in thought.

Conan tried to persuade her in another way: "Aunt Yingli, are you free now?"

Hibiki Eri adjusted the shoulder strap of her bag. "I'm the consulting lawyer of this hotel. I came here to listen to the situation regarding the labor dispute. I'm planning to go back now."

"Consultant?" Upon hearing this, Sera Masumi was immediately happy.

So Conan and Sera Masumi each put their hands together and pleaded, "It would be more convenient this way, please!"

Kisaki Eri looked at the two of them speechlessly.

Kudo Yuki suggested: "Don't feel embarrassed, Attorney Fei. In fact, I have a small request. If Attorney Fei agrees, there will be a very good reward."

Kisaki Eri raised her eyebrows slightly, revealing a curious look.

Kudo Yuki continued, “I know Attorney Hime has been busy with work and probably has few opportunities to relax with her family.

It just so happens that my Polo Café has been developing some new dishes recently, and is planning to launch a tasteful coffee and cuisine combo, which will be on the market in a while.

But I would like to invite Mr. Maori, Xiaolan and Lawyer Fei to taste it together and experience our new product in advance.

You can enjoy the food in the private room, and you can take it home if you can't finish it. You can also order all the new dishes. I think Mr. Mao Li and Xiao Lan will like it very much. How about you, Mr. Fei, just relax with your family?"

Hearing this, Conan and Sera Masumi's eyes lit up and they looked at Kisaki Eri.

Conan thought to himself: "If Kisaki Eri agrees, Uncle Maori and Xiaolan will be very happy. Maybe this will be an opportunity to make the relationship between their family more harmonious."

Masumi Sera nodded secretly, thinking that this suggestion was very good.

Hibiki Eri's heart moved. She lowered her eyes slightly, thought for a moment, and looked up at Kudo Yuki. "Your proposal is very tempting, but I need to think about it."

Kudo Yuki smiled and nodded, saying with understanding: "Of course, Attorney Fei can take your time to think about it. I believe Mr. Maori and Xiaolan will definitely look forward to this tasting event."

Kisaki Eri was silent for a while, thinking to herself: "It's been a long time since I've spent time with Kogoro and Ran. The food at the Poirot Cafe has always been well-received, and the new dishes sound so tempting, maybe it's a good idea to agree to it."

Fei Yingli smiled faintly and said: "Okay, I promise you."

Conan and Sera Masumi immediately smiled when they heard Kisaki Eri agreed.

While searching her bag, Kudo Yuki asked, "Lawyer Fei, what kind of theme room would you like your family of three to dine in?"

Kisaki Eri thought for a moment and said, "As for the style... let's try something a little warmer. After all, it's been a while since we've had a good family get-together."

Kudo Yuki took out a free card for the new European-style theme room from her bag and handed it to Kisaki Eri. "Keep these three cards. When you want to go, just take them with you."

After putting the free card into her bag, Hibiki Eri walked to the front desk and started chatting animatedly with two female staff members.

"Of course we know, Detective Maori Kogoro."

"That's the sleeping Kogoro, right?"

"But we didn't expect that it was your husband, Lawyer Fei."

Hibiki Eri spoke calmly and naturally: "My husband asked me to do this. I think the hotel where I work as a legal consultant seems to be threatened. I hope I can lend a hand."

The female staff praised: "As expected of a famous detective, you are so well-informed!"

"My husband said that the police also had the code for the second explosion..."

"Yes, it has been given to us. This is the code."

Kisaki Eri looked at the secret code in her hand and pondered.

The female staff member asked: "Lawyer Fei, can you decipher this code?"

"Well." Hibiki Eri smiled faintly: "Maybe I will give up soon and ask my husband for help."

Conan and Sera Masumi were standing next to Kudo Yuki. When they heard this, they were both stunned with shock.

Kisaki Eri took three pictures of the secret codes with her cell phone. The four of them came to the corridor and stopped in an empty place to look at the secret codes.

She put one hand on her waist. "Then, leave the code to us. Although we told them not to contact the police for the time being, we must decipher the third code that appears in Room 2114 before five o'clock in the evening, before the bomber calls us."

Kisaki Eri looked at the Kudo siblings and Sera Masumi. "Have you untied them?"

Masumi Sera and Conan answered.

"That's it."

"We've already guessed half of it."

Kudo Yuki looked at the code note, raised an eyebrow and gave a hint: "The first word of each code is framed in a box. If we can solve this clue, we will know who the bomber is."

Sera Masumi and Conan looked at each other, then immediately lowered their heads and began to analyze the secret code in front of them one after another.

"The first explosion occurred in room 3420. The first code, after removing the first framed word, is a combination of three thousand four hundred and twenty."

"The second explosion occurred in room 2614. The second code is also a combination of without the first letter."

Conan paused and continued, "So if the code this time is also a permutation and combination, then after removing the first letter, the remaining hidden numbers and words should be..."

"Two, four, thousand, hundred, ten, these five words."

Kudo Yuki reminded him, "There are 12 possible combinations of numbers. This hotel has 25 floors, and each floor has 25 rooms."

柯南开始逐步排除：“那么，有可能的就是 1124 室、1214 室、1412 室、1420 室、2114 室和 2410 室，这六个房间。”

Upon hearing this, Kudo Yuki guided the three people to think: "Having said that, I have no idea in what order they are arranged."

Hibiki touched her chin and thought: "But it's very strange! The first and second explosion warnings were both sent via email. The criminal's request was that if the code was cracked, the answer should be sent to a designated email address, right?

But this time, they placed the code on paper in the room and called to announce the explosion. Even if they used a machine to change the voice, the risk was still too high.

Masumi Sera folded his arms across his chest and analyzed the case: "Yes. Mr. Hayashizaki, who said he found the code in Room 2114, said that after he checked in and entered the room, he found the paper. So there are only three people who could have put this paper there."

Conan pondered and found the key clue to the case: "If it was left by the previous guest of Mr. Hayashizaki, it should have been cleaned up by the cleaner.

The only people who can give the secret code are Ms. Ronda, the cleaner who cleaned the room before Mr. Hayashizaki moved in. Mr. Kuroishi Yuto, the doorman who carried the luggage to the room. And Mr. Hayashizaki who is currently living in that room.

Masumi Sera took out his cell phone and saw the time, then said in panic, "Oh no! There are only 50 minutes left before the bomber calls."

Hibiki Eri urged: "Hurry up and find those three people to question them. The answering room..."

She looked at Sera Masumi and said, "Just use your room. Your room is right next to Mr. Hayashizaki's room, so it's more convenient. Then I'll go to the front desk and ask them to call those two people over."

Having said that, he ran towards the rooms of those people.

Conan responded: "Yeah."

Kudo Yuki nodded, waiting for the truth of the case to be revealed.

There was panic in Sera Masumi's eyes, and she smiled and said, "Well, then I'll go back to my room and clean up first."

When Conan saw that Kisaki Eri had disappeared, he looked up at Sera Masumi. "Your room isn't messy."

Masumi Sera leaned over to explain, "Aren't there tea cups spread out all over the table?"

Kudo Yuki's lips moved slightly: "It's time to clean it up."

Sera Masumi also ran back and said, "Anyway, just take your time!" As she spoke, she quickened her pace and ran towards her room.

Conan rolled his eyes speechlessly until she disappeared from his sight.

After returning to the room, Sera Masumi gently closed the door. She quickly walked to Akai Mari and told her what happened.

When Akai Mari heard this, she put her hands on her hips and her face became serious: "Bringing the suspect of the bombing to this room for questioning? Are you stupid?"

Sera Masumi quickly put on a smile, with a hint of apology in her eyes, and begged, "I'm sorry, Mom. I can't refuse now that I've said that."

Akai Mary thought about the interests involved. "However, this is the only way to find the bomber. If a room is bombed and all the guests in the hotel are evacuated, I will be exposed."

Sera Masumi continued to coax her, pulling Akai Mari's arm and shaking it gently: "Mom, just promise me. I will be careful and will never let you get exposed."

After repeated requests from Sera Masumi, Akai Mari finally nodded and agreed reluctantly. "Okay, but you must be careful not to let anyone know of my presence."

Seeing that her mother agreed, Sera Masumi quickly nodded and assured her, "I understand, Mom, don't worry."

Before everyone arrived, Akai Mary looked solemn. She turned on her daughter's mobile phone and made a voice call, connecting it to her own phone.

Then she hid in a secluded corner, holding the phone, with her ear pressed tightly against it, listening to their conversation.

A few minutes later, Eri Kisaki and the cleaner Moriko Ronda were sitting opposite each other in the living room, separated by a coffee table.

Kisaki Eri crossed her legs, leaned forward slightly, and asked Moriko Norita what had happened.

Moriko Ronda replied a little stiffly: "The code was found in Room 2114 where Mr. Hayashizaki stayed. I was the one who cleaned this room. There was no code when I cleaned the room. But I really didn't want to clean that room."

"Why?"

"Because the hotel stipulates that all rooms are non-smoking, but that person would smoke secretly, and I can't stand the smell of smoke."

"What does Mr. Hayashizaki do?"

"He's a novelist! I heard that his books are quite popular. He often hides in our hotel room to finish his manuscripts before the deadline."
