I'm in Detective Conan, but it's a chaotic battlefield.

"What are you doing here?" Tsujimura Kimie asked in an unfriendly tone, but Chen Nuo knew she was doing it on purpose to avoid others discovering the relationship between her and her mother.

Sachiko's fiancé, Guishan, explained, "Mom, I brought Sachiko here. I wanted her and Dad to get to know each other, but Dad refused to come out of his study."

"Are you my mother's friends?" Sachiko Katsuragi greeted her warmly, seemingly eager to please her "mother-in-law."

“This is none of your business,” Kimie Tsujimura shouted. “And please don’t call me Mom. You’re not qualified yet.”

The entryway immediately fell silent.

No one spoke, and Ms. Sachiko stood there somewhat awkwardly.

Kimie Tsujimura turned to Kogoro Mouri and said, "I'm sorry to have made you laugh. Please come with me."

After she finished speaking, she led everyone to the study on the second floor.

Chen Nuo followed.

Just as she reached the second floor, Tsujimura Kimie's father-in-law came up to her and showed her the big fish he had caught. Tsujimura Kimie managed to brush him off with a few words and explained to everyone that her father-in-law was old and had a bad memory.

But Chen Nuo knew that this old man was actually a scapegoat she had found.

The group arrived at the door of the study, and they could hear melodious music coming from inside, even through the door.

"Honestly, the music's so loud again." Kimie Tsujimura complained as she inserted the key into the lock.

Click.

As soon as the door opened, even louder music rushed in, as if a symphony orchestra was practicing in the study.

Upon entering the room, Chen Nuo saw a bald, middle-aged man resting his hand on the desk, seemingly dozing off.

"Honey, honestly, you fell asleep again and didn't turn off the music." Kimie Tsujimura walked over and gently nudged him.

Tsujimura Isao's body collapsed to the ground.

His obese body slammed onto the floor with a dull thud, even drowning out the symphony played at maximum volume.

.

"Husband, what's wrong, husband?" Tsujimura Kimie cried out as she lay on the ground.

Heiji Hattori and Conan stood on the other side of the corpse.

Hattori Heiji shook his head: "It's no use, the person is beyond saving."

At this moment, the others heard the noise and ran over, but were stopped by Kogoro Mouri: "No one is allowed in the study. Mrs. Tsujimura, do not touch the body before the matter is investigated. Ran, call the police immediately."

Everyone else who heard this stood at the door.

Xiaolan skillfully took out her phone.

While Ran was reporting the incident to the police, Heiji Hattori had already begun investigating the clues.

Hattori Heiji was surprised to encounter another case, which gave him a pleasant surprise, and he felt excited and thrilled.

He originally intended to come along and test the guy named Chen Nuo further, and now, perfect timing, there's a case that can serve as the battlefield for their first confrontation.

Heiji Hattori's observational skills are actually quite good.

He quickly discovered the real hole in the victim's neck and deduced that the murder weapon was likely a needle-like sharp object.

He then searched the ground around the body and, to his surprise, actually found a needle lying on the ground.

Did the murderer not take the murder weapon?

Hattori Heiji bent down to pick up the needle, and then—

duang!

He bumped his head into Conan's.

"Damn it! What are you doing, you brat? This isn't for kids to play with," Hattori Heiji said, displeased.

Conan: "I was just playing a detective game, but Heiji-nii, do you also think there's something wrong with this needle?"

Hattori Heiji thought to himself, "Isn't this obvious?"

But this kid looks like he's still in elementary school, right? He seems to have the potential to be a detective.

Hattori Heiji picked up the needle, glanced back at the guy named Chen Nuo, and found him chatting with Xiao Lan, seemingly uninterested in the case at all, not even as curious as this kid.

Could it be that he is not Shinichi Kudo, but just looks a bit like him?

Hattori Heiji had some doubts, but decided to solve the case first.

Soon, Inspector Megure arrived with a group of officers.

After a brief search and evidence collection, it was determined that this was a murder case, and a locked-room murder case at that.

Kogoro Mouri, perhaps spurred on by Heiji Hattori, a high school detective, thought to himself that he absolutely could not lose to such a brat.

They actually beat me to the punch and made the deduction.

Unfortunately, he fell into the murderer's trap, mistakenly believing that the victim's father was the killer.

There are no leads on Hattori Heiji's side yet, but he seems very interested in fishing line. He thinks it's a key clue and is standing there thinking about how to use the fishing line to turn the study into a secret room.

Although Conan was suffering from a cold and his mind wasn't very clear, he was still much better than Kogoro Mouri. He dragged his tired body into the investigation and quickly discovered the real clue.

Everyone is busy in their own way.

As for Chen Nuo—

Xiaolan's legs are so white and soft...

In the end, Conan couldn't stand it anymore. He had originally wanted to watch the showdown between Chen Nuo and Hattori Heiji, thinking that he might be able to find some clues.

I never expected that this bastard would have absolutely no sense of honor as a detective. He's really despicable.

Conan was about to give Kogoro Mouri an injection.

Suddenly I felt a strong sense of discomfort in my body.

It was as if I had suddenly caught a severe cold, and I couldn't even hold the wristwatch-shaped anesthetic needle steady.

No, I have to solve this case quickly. Conan tried to get up by supporting himself with his hands on the ground.

"Conan, what's wrong?"

"Are you alright? Shall I take you to another room to rest?"

Xiao Lan and Chen Nuo's voices rang out in front of him, and then he felt himself being picked up by Chen Nuo and vaguely arrived at the guest room.

Conan, lying in bed, felt increasingly unwell.

His heart felt like it was going to jump out of his chest, and he felt like he was about to die.

Damn it, is it that bottle of wine?

Could the other party be an assassin sent by the Black Organization?

Just as Conan was lost in thought, he suddenly heard another voice that filled him with despair.

"Let's go out and let him lie here and rest for a while," Chen Nuo advised Xiao Lan.

"But... is this okay?"

Chen Nuo: "It's okay, it's just a cold. I'll feel much better after a good night's sleep."

Conan really wanted to sit up and slap him.

Doesn't this guy realize he's about to die? A normal cold doesn't cause this kind of condition.

If Ran hadn't been there, he would have really thought Chen Nuo was deliberately trying to murder him. But Ran definitely wouldn't stand idly by, Conan thought.

Ran: "Alright then, Conan, you get some rest."

Conan was struck dumb.

His vision went black, and he almost fainted from the shock.

When Conan opened his eyes again, he only saw the backs of the two people walking away side by side.

and……

In a daze, he seemed to see Chen Nuo putting his arm around Xiao Lan's shoulder as they went out.

Impossible. Xiaolan would never let someone put their arm around her shoulder and not resist. Even he himself has never hugged her in that way.

Conan was absolutely certain that he must be seeing things because he was dizzy and his eyes were playing tricks on him.

However, the cold sweat he had just broken out in made Conan feel even weaker than before.

He gasped for breath, feeling that impending death again.

After tossing and turning in bed for a few minutes, Conan was shocked to discover—

He had somehow reverted to Shinichi Kudo's body.

Faced with such an incredible situation, countless thoughts flashed through Shinichi Kudo's mind.

However, after hesitating for a moment, he decided to use this body to make things clear to Xiao Lan first, so that Chen Nuo wouldn't continue to take advantage of Xiao Lan by occupying his body.

Thinking of this, Shinichi Kudo got up, grabbed a random piece of clothing from the closet, and headed towards the crime scene.

When he arrived at the study, Hattori Heiji was reasoning and concluded that the murderer had used a fishing line to put the key into the locked room by the victim's father.

However, this judgment is wrong.

Because the deceased was sitting on the ground, it would have been impossible to arrange the keys in that shape using a fishing line.

As for the murderer, he had already found out; it was that terrifying woman who was so audacious as to kill someone in front of a detective.

"Wait a minute!" Shinichi Kudo appeared in the doorway, leaning against the door frame.

Everyone turned their attention to him.

"Shin...Shinichi?"

Xiaolan stared in shock at his sudden appearance, then turned her gaze to Chen Nuo, who shrugged at her with an expression that said, "I told you long ago I wasn't Shinichi Kudo, didn't I?"

Xiao Lan walked over in a daze, staring blankly at him: "You..."

Shinichi Kudo: "You idiot, how many times have I told you, how can you still mistake me for someone else?"

"But...but..." Xiaolan said in a sobbing voice, her eyes filled with tears, "I don't know where you went. You haven't shown up at all. How am I supposed to know if you're lying to me?"

Shinichi Kudo's heart softened, and he said gently, "Alright, we can talk about our business later. Let me solve the case first."
