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

The gate closed, and Matsumoto Sayuri finally noticed Tohru Tono following behind the group. She winked at Ran as if she had discovered some secret.

"No, no..." Xiaolan quickly waved her hand, her face slightly red.

Conan stood aside, unable to get a word in edgewise, and could only grumble to himself.

What do you mean by an arrogant brat... He's just aware of his own intelligence!

And what does Matsumoto-sensei mean by this? It feels like everyone is trying to poach his men since Shinichi Kudo isn't around.

"It was Ms. Kawasaki, your good friend, who gave me the invitation—she has an emergency to attend to and can't come to the wedding in person, so she asked me to take care of you in her place." To avoid embarrassing Ran, Tohru Tono naturally took over the conversation and explained his purpose.

This time, it was Sayuri's turn to blush.

Because she suddenly remembered this. The night before last, she had talked to her best friend on the phone about Tohno Toru, and the content was all things that couldn't pass censorship.

Even though she's about to get married, he keeps saying inappropriate things to her.

It's so embarrassing.

Although she knew that everyone in the circle except herself was quite promiscuous, Matsumoto Sayuri, being a pure-hearted romantic, always believed that beautiful appearances were a dime a dozen, but interesting souls were one in a million.

That's why she finally recognized her first love, Junyan.

only......

Thinking of this, Xiaobaihe's expression suddenly became somewhat downcast.

Tohno Toru noticed that her expression was off, and combined with the information he knew, he immediately understood what was going on.

She probably thought of her first love, Toshihiko Takasugi.

Matsumoto Sayuri's life is pretty tragic. She finally found her first love, whom she had cherished since childhood, only to discover that he not only didn't remember her at all, but also harbored thoughts of killing her so that her father would experience pain...

Takasugi Toshihiko and Uzumaki Nagato definitely have things in common.

Fortunately, the ending seems to be pretty good.

The old thief from Qingshan was still friendly to his childhood sweetheart.

......

As the group was chatting animatedly, Sayuri Matsumoto's best friend, Kazumi Takenaka, walked in and brought her two cans of lemon tea.

"Thank you!" Little Lily ran over happily and took the warm lemon tea with both hands.

Inserting a straw, the sweet and sour taste filled her mouth, and a happy smile gradually appeared on her face.

Chapter 10 My First Trial

The pleasant chatter quickly came to an end, and staff members in formal attire came in to remind everyone in the room that the ceremony was about to begin.

During this time, Toshihiko Takasugi, the heir to the Takasugi Group and the groom of this wedding, also arrived at the bride's room.

When Sonoko saw him, she secretly leaned over to Ran and said that he was "indecisive and not very reliable," but the next second she witnessed a kiss that seemed to last forever.

Everyone present was bombarded with a dose of PDA.

Even Conan blushed a little while watching.

Sonoko, her mind still clouded by love, stopped commenting, her face flushed, her gaze constantly drifting towards Toru Tono's side.

Looking at the young people, Toru Tono thought they were really naive and unsophisticated.

But thinking about it, it makes sense. No matter how precocious these people are, they are still just high school students and not yet adults.

It's perfectly normal to yearn for a sweet romance.

Unlike him, who is already a mature and steady adult who has just turned 20, long past the age of romantic love.

Tohru Tohru sighed sadly.

......

The group chatted and laughed as they left the room, giving the bride time to prepare on her own.

But before he could take more than a few steps, Toru Tono heard a crisp "clang" coming from the room, like the sound of an aluminum can falling to the ground.

There was also the sound of a heavy object hitting the ground.

Everyone had obviously heard the strange noise, and Conan suddenly turned around and asked, "What was that sound just now?"

"It seems to be coming from the teacher's room." Xiaolan reacted quickly and immediately ran back to the door.

She first called out "Teacher" and knocked on the door. When no one responded, she simply turned the unlocked doorknob.

"what!!!"

Ran and Sonoko let out a piercing scream as they opened the door.

Toru Tono, who arrived later, saw the bride lying on the ground vomiting blood and picked up his phone to call an ambulance.

......

Police officers responded in a second, and Inspector Megure arrived at the scene wiping away sweat.

Who would dare to cause trouble at their boss's daughter's wedding? They clearly don't respect our Investigation Division at all!

Looking at Matsumoto Kiyonaga's expressionless, serious face, Inspector Megure felt immense pressure.

If he can't solve this case, he probably won't be able to stay in the Metropolitan Police Department anymore.

He looked around but didn't find Shinichi Kudo or Kogoro Mouri.

Totally hopeless.

Kudo, I miss you!

......

Conan routinely sneaks into the forensic department to look for clues, but after searching for a long time, he still can't find anything wrong.

He looked down at the empty can and felt a little strange.

"There are no marks on Matsumoto-sensei's body that indicate he was struck by an external force, which proves that his coma was caused by internal factors."

"It's very likely that someone poisoned it."

"The problem is that the lemon tea, which was the most likely poisoning agent, was completely drunk. I also checked before Matsumoto-sensei got into the ambulance; there were no traces of poison on his gloves or lips..."

"If we wait for the hospital to find out the cause of Matsumoto-sensei's poisoning, it will take too long, and the murderer could easily destroy other clues at will."

"Without determining the modus operandi, there's no way to identify the suspect. This case is quite tricky..."

Conan fell into thought.

......

After seeing that the case had made little progress for a long time, Tohno Toru felt it was time for him to take action.

He casually leaned closer to Inspector Megure, who was anxiously wiping away sweat, and muttered to himself, "Sodium hydroxide..."

? !

Inspector Megure and Conan, who happened to be nearby, were startled.

Both of them looked at Tohno Toru at the same time.

Tohru Tohno, under Inspector Megure's gaze, gave a shy smile: "I smelled a pungent odor near that can of lemon tea earlier, which was a bit strange at the time... Now that I think about it, it was probably caused by the evaporation of sodium hydroxide."

"Because we come into contact with it frequently, I remembered it very quickly," he added.

Inspector Megure was filled with respect.

"you are?"

He suddenly realized that he had probably saved his hat.

It's truly a blessing for Inspector Megure; he always seems to run into detectives whenever he's at a crime scene!

"Ah, my name is Toru Tono, and I'm an inventor."

"Oh, it's Mr. Tono." Inspector Megure nodded, but his expression visibly turned colder.

Looking at Inspector Megure, Toru Tono muttered "mmp" to himself, unsure whether to say it or not.

Why do you look so disappointed when you hear it's not a detective?

No matter how you look at it, being an inventor sounds more impressive!

Toru Tohno felt that the people in this world had some problems with their thinking and values, and that he urgently needed to correct them.

"Actually, I have some clues about this case..."

Inspector Megure had originally planned to hand in his resignation as soon as he got back, but after hearing this, he felt confident that he was ready to go.

He's still a detective!

He walked over and put his arm around Tohno Toru's shoulder. "Tohno, what are your thoughts?"

Inspector Megure threw you the fruit, little brother.

Tono subtly pulled her hand away from his and walked to the can of lemon tea.

After asking a classmate from the forensic department for a pair of gloves and putting them on, he slowly picked up the aluminum can, turned it upside down, and showed the contents to Inspector Megure and Conan, who was watching nearby, through the small opening of the pull tab.

"What? This is..." Conan had a flash of inspiration and instantly understood.

As the others gathered around, Toru Tono continued, "Although we don't know how the culprit managed to make the liquid in the can evaporate out of thin air, anything done will leave a trace."

"The slightly concave part at the bottom of the jar is the evidence."

"In a confined space, when a solution evaporates, it absorbs heat from the surrounding air, causing the pressure inside the container to decrease."

"The air pressure inside an aluminum can is lower than the atmospheric pressure outside, causing the can wall sandwiched in the middle to deform inward."

Tohru Tono twirled the aluminum can in his hand, drawing a graceful arc in the air.

"The dents on the cans prove that the perpetrators deliberately allowed the solution inside the cans to evaporate."

Why would he do that? It was clearly to cover up evidence of his poisoning.

"In other words, the culprit poisoned Ms. Matsumoto using this can of lemon tea."

Tohru Tono walked to the nearby water dispenser and filled the can with water.

Then he pulled something out of his pocket that looked like an electronic thermometer.
