Conan: I've been linked to the tech tree system.

Although he never considered himself a detective, he couldn't help it if others insisted on labeling him that way.

Moreover, in the world of detectives, having multiple titles like these is quite advantageous.

As his fame grows after solving cases, more people will likely pay attention to his inventions, right?

......

[Ding, Detective storyline system quest triggered: Diplomat Murder Case]

Mission objective: Solve the case first.

Mission completion reward: 200 Detective Points

The system also triggered a mission at this time, rewarding 200 Detective Points. It wasn't a lot, but it was still very useful for Toru Tohno, who had been under immense pressure recently due to the Black Organization's attention.

......

Hattori Heiji felt bored when he saw that Tohru Tono was just nodding without answering.

Why does this detective have absolutely no fighting spirit...? Shouldn't two detectives, after getting to know each other, immediately separate like magnets with the same polarity, their eyes locked, sparks flying between them...?

Shouldn't it be like this?

The teenager, still a bit eccentric, was completely baffled.

The adult Toru Tono looked around and spotted Conan Edogawa, who had a cold and had been tricked by Heiji Hattori into drinking strong liquor. He immediately burst out laughing.

He walked over and ruffled Conan's hair, saying with a smug look, "How could you be so careless? Did you catch a cold?"

"Yeah, not only did he catch a cold, but thanks to someone, he also drank a glass of baijiu." Ran, standing next to him, didn't give Heiji Hattori a friendly look. "Look at Conan, he seems to be drunk and feeling terrible."

"I told you it's a miracle cure for colds." Hattori Heiji protested, insisting he was fine. "Speaking of which, you and Kudo Shinichi are both detectives from the Kanto region. Do you know where he went?"

"Shinichi Kudo?" Toru Tono said he didn't know the person. "I only recently moved to Beika Town from Kyoto, and I've never met this Shinichi Kudo before."

"Oh." Hattori nodded, looking at Ran who seemed to be deep in thought.

Tohno knew that he was probably thinking that Shinichi Kudo was hiding nearby, but he didn't say anything.

If nothing unexpected happens, I'll be able to meet Shinichi Kudo in person today.

Tohno Toru, seeing that Conan was clearly struggling to control his limbs but was still trying to solve the case, reminded Ran, "Conan looks very ill—he looks like he's about to faint. Ran, you should find him a room to rest for a while."

Find a secluded place to transform quickly; it would be bad if the organization saw you transforming anywhere.

Because Ran was standing behind Conan, she couldn't see his face. When she heard Toru's words, she leaned over and saw that Conan's face was pale and his forehead was covered with a fine layer of cold sweat.

"Oh! Why do you look so pale! If you feel unwell, you should tell your sister, Conan!" Ran was startled, afraid that the child would get sick from the fever, and hurriedly carried him to a room to rest.

However, before leaving, Conan seemed to reach out his hand in this direction, as if to say, "Don't take me with you, I can still fight."

This reminded Tohru Tohru of whether Heiji Hattori had mistakenly identified the wrong culprit in his first attempt at deduction.

Because he was so eager to settle things with Shinichi Kudo, who was hiding in the shadows, he overlooked the illogicality of his own reasoning... He was indeed a bit inferior to Shinichi Kudo, who had been through countless battles at such a young age.

Is it because there are too few murder cases in Osaka that people don't get enough practice?

Or is it because he's already Little Black, so the probability of Little Black appearing on screen alongside him will decrease accordingly...?

......

Heiji Hattori noticed that Toru Tohno's gaze was shifty, and he felt that Toru was thinking about something impolite.

"So after hearing Inspector Megure's clues, do you have any leads on this case?" Hattori Heiji casually asked Tohru Tono, not expecting any definite answer.

After all, he knew the level of those police officers; at most, they'd only look at footprints at the scene, and the detectives had to go and retrieve even the ballpoint pen rolled up in the blanket themselves...

There's no such thing as a detective who can deduce the truth of a case from clues obtained from useless police reports.

"Yes, I already know who the culprit is," Toru Tono replied casually.

"I knew it... what did you say?" Hattori Heiji didn't react at first, but after realizing what Tohno Toru had said, he immediately looked at him with a shocked expression.

What do you mean? I've been searching for ages and just started to get a clue. How did you know the killer as soon as you arrived at the scene?

Inspector Megure, who had been listening in, also had a sudden realization. He knew that his friend Tono would definitely be able to defeat this kid who spoke with an Osaka accent!

I just didn't expect it to be so fast.

Chapter 35 You're making me lose face.

"Wait, you're not kidding me, are you?" Hattori Heiji tugged at Tohru Tohru's sleeve, his head spinning. "Detectives have to be responsible for what they say!"

Tohru Tohru remained silent, but Inspector Megure spoke up for him: "Since you say so, Tohru-kun, it means you have enough evidence to prove who the murderer is!" The deliberately amplified voice attracted everyone's attention.

Heiji Hattori frowned slightly. He thought he was competing with Shinichi Kudo, who was hiding in the shadows, to see who could solve the case first. How did another expert suddenly appear out of nowhere?

He didn't think that the detective, whose work had never even been published in the newspapers, could solve cases faster than Kudo and himself, but he'd listen to what he had to say anyway.

Under everyone's gaze, Tono cleared his throat, turned to the diplomat's wife who had a grim expression, and dropped a bombshell: "The person who murdered the diplomat is you!"

"Mrs. Tamura!"

"What?!" Everyone was shocked when these words were spoken.

"Wait, wait, what evidence do you have for saying that?" Hattori Heiji quickly interrupted Tohru Tono. "Mrs. Tamura came into this room with us before... You saw it yourself, the key to this room is in the diplomat's pocket—this is a classic locked-room murder case, and before this, Mrs. Tamura didn't have any time to enter this locked room at all."

"Is that what you think?" Tono grinned, pointing to the doorway. "But from the moment you opened that door, this place was no longer a secret room."

"What?" Inspector Megure, being a dutiful straight man, exclaimed in surprise at the opportune moment.

Hattori Heiji, however, had a sudden flash of inspiration and felt as if he had vaguely grasped something: "...I see. We have never been able to determine the time of the victim's death. If the murderer committed the crime after we opened the door, then this does not really count as a locked-room murder case."

"But according to you, Mrs. Nadam killed the diplomat in full view of everyone?"

"How can this be?"

“Nothing is impossible.” Toru Tono stepped forward, walked to the diplomat’s body, picked up the water glass next to him, and made a “cheers” gesture to Mrs. Tamura.

Mrs. Tamura's pupils gradually dilated, revealing an expression of disbelief.

"By using special means—such as putting sleeping pills or similar drugs in the diplomat's drinking cup beforehand—it is entirely possible to keep the diplomat quiet and only make his move when you enter the room with him—making you mistakenly believe that he is already dead at that time."

Tohno Toru demonstrated to everyone how to stand behind a diplomat and secretly raise his hand. Sure enough, because of the pile of books on the table, no one could see his specific actions clearly.

"But what did the lady use to kill the diplomat?" Inspector Megure asked, puzzled.

“Of course it is this.” Toru Tono stretched out his hand, gesturing for the police officer behind him to place a bunch of bright yellow keys that had been found on the diplomat into his palm.

Then he opened the oval-shaped keychain and showed everyone what was inside.

“Look here, the inside of this keychain has a noticeable groove, which is obviously used to hide something.”

"And based on my observation, Mrs. Tamura had the same keychain as the deceased... Judging from the size of this groove, the most likely thing hidden inside is a poison needle, right?"

"Mrs. Tamura must have taken out a poisoned needle hidden in the keychain and killed the diplomat from somewhere you couldn't see."

After listening to Toru Tohno's reasoning, Inspector Megure walked up to Mrs. Tatsumura with a stern face and said, "Could you please take out your keychain so we can take a look?"

Seeing that the evidence was irrefutable, Mrs. Tatsumura did not show any obvious panic. Instead, she took out her keychain and handed it to Inspector Megure, saying, "My keychain does have a groove—but it only contains ordinary embroidery needles for my embroidery, not any poison needles."

Inspector Megure opened the keychain and handed it to the forensic department. The forensic department scanned it with Toru Tono's previous invention and, as expected, did not find any obvious drugs on it.

Everyone looked at Tohru Tohru with puzzled expressions.

Tohru Tohru twitched the corner of her mouth. She hadn't expected this person to have such a strong mentality. No wonder she was a woman who could become a diplomat's wife.

However, using his invention to deactivate biological poison attached to poison needles with remote high temperature... such a trick is still a bit like showing off one's limited skills before an expert.

Recently, prisoners like you have been able to put together a mahjong table in prison!

Toru Tono explained to everyone the principle that biological toxins can be deactivated by high temperatures, and then walked over to the diplomat and pointed out the needle marks on his neck.

"The toxin on the poison needle can be killed, but the traces left by the crime cannot be faked."

"Now that we know your modus operandi, when we take the victim's blood for a test, we'll be able to find out exactly what kind of poison you used—it should be a very fast-acting neurotoxin, right?"

"Let me guess... is it the venom of the blue-ringed sea snake?"

With the evidence irrefutable, Mrs. Dacun gave up the struggle.

She stood there expressionless, without the remorseful look of the other prisoners, calmly recounting her motives for the crime.

It turns out that her former husband was not the deceased diplomat Tatsumura Isao—but rather Tatsumura's rival, Yamashiro Kenji, who was also a diplomat.

After Kenji Yamashiro was brought down by Tatsumura's despicable means and imprisoned, he had no choice but to entrust his daughter to relatives for upbringing. Only then was Tatsumura's wife, who was completely unaware of the situation, deceived by Tatsumura Isao's sweet words and became his wife.

Coincidentally, one day Tatsumura Isao's son gave Tatsumura Isao a photo of Yamashiro Kenji's daughter, Sachiko, and claimed that she was his girlfriend.

Upon seeing Sachiko's photo, Tatsumura Isao flew into a rage. In a moment of irrationality, he revealed to Mrs. Tatsumura, who was standing nearby, everything he had done to frame Yamashiro.

It was this hatred that gave rise to Mrs. Tatsumura's idea of ​​killing Tatsumura Isao.

......

After hearing all this, Toru Tono had only one feeling.

Your circle is really chaotic.

His son really does have the same taste as his father; the people he likes are all direct relatives...

......

[Mission Completed: Diplomat Murder Case. Reward: 200 Detective Points]

Mrs. Tatsumura was handcuffed and taken away by the police officers, and the mission was successfully completed. Tohno Toru still hadn't seen Shinichi Kudo, who was supposed to be at the scene.

It's probably because he solved the case too quickly; Conan was still transforming.

However, the case ended early, and Tohno Toru seemed to see Ran heading straight for Conan's room...

Oh no, is Conan still transforming?

If Ran were to see Conan transforming into Shinichi Kudo live, it would be quite a spectacle.

Chapter 36 Large Conan

To cover for Shinichi Kudo, Toru Tono asked Ran some questions about Shinichi Kudo.

Sure enough, as soon as she heard the name Shinichi Kudo, she stopped and started complaining, bringing up the theory she'd heard from Heiji Hattori that "Shinichi Kudo is definitely watching your life all around you."

“Actually, it might not be him personally who was there,” Toru Tono added, helping Conan out. “Isn’t Conan a distant relative of Professor Agasa? It seems the Kudo family is also related to Professor Agasa by blood… Maybe he learned about your recent situation from Conan.”

"Huh? Is that so?" Xiaolan thought about it and realized that it was indeed very possible.
