Lin Shinichi's words were like small droplets of water sprinkled on the flames, and instead of extinguishing the fire, they made Conan's fire of reasoning burn a little stronger.

Conan did not obediently go back to his seat, but said with a focused expression:

"You see, the rest of the library's staff are wearing short-sleeved shirts, which shows that the library doesn't have a very strict dress code for staff."

"Only the mayor of the Tsugawa Pavilion still dresses so formally on a hot day, and he covers himself so tightly with a suit jacket."

Lin Xinyi: "......"

You little devil who wears a suit and bow tie all year round, don't question that others wear suits in summer!

"People are curators, so it's normal to pay more attention to clothing etiquette, right?" Lin Xinyi questioned helplessly.

"Nope." Conan rubbed his chin, and a sharp light flashed in his eyes: "He only wore a suit and no tie today, if he pays special attention to clothing etiquette, he will not miss this." ”

"What's even stranger is that he pulled the collar of the shirt inside so high that the shirt sleeves were pulled into the cuffs of the suit."

"According to dress etiquette, the shirt collar should show about 1 inch of the suit, and the shirt cuff should show about 0.5 inches of the suit cuff."

"And the way he wears it, the collar is exposed too much, and the cuffs are completely retracted, which is very unsightly."

"Not to mention, it will be a little difficult to breathe if you stick your neck with your collar like this."

"So... It always feels very wrong. ”

"It's as if he deliberately wanted to cover himself a little thicker with this formal suit so that the skin on his neck and wrists would not be exposed."

"I think you're just thinking too much..."Lin Xinyi was still a little unimpressed.

He just wants the big detective to play his character as a primary school student now, but he doesn't have the heart to play this kind of deduction game with him that doesn't fit his age:

"What does it mean if you wear clothes a little crooked?"

"It's not about participating in any high-end banquets, it's just a daily work occasion, and you don't have to talk about clothing etiquette so rigidly."

"Look at me, I'm wearing a suit and no tie, and the cuffs of my shirt aren't shrunk in, but they don't show exactly 0.5 inches, right?"

"Am I some bad person?"

"This—" Conan was speechless, but he was still reluctant to give up.

After all, after so many practices, Conan has vaguely summed up the law:

When he discovers a slight anomaly from someone, as long as he investigates deeply, he will inevitably investigate something earth-shattering from that person.

"Lin, I think it's necessary for us to investigate that Tsugawa curator in depth."

"Trust me, my instincts are accurate."

Conan said with a serious face.

"Hey, still disobedient?"

Lin Xinyi's tone sank, with a threat in his eyes:

"Well, you go investigate, I'll give Miss Maori a lesson here."

"Since you think reasoning is more important, then you can leave with peace of mind and leave your sister Xiaolan alone with me."

With that, he sat back in his seat, picked up the book, turned his head to look at Mao Lilan, and continued to talk about the lecture with a devoted.

Conan: "......"

Bastard! With Xiaolan here, how dare he leave alone?

His weakness has been completely grasped by Lin Xinyi.

"Well... I'll stay here and read..."

Conan held back for a long time, and finally wanted to cry without tears.

He obediently took the Ultraman Encyclopedia Illustrated Book, and forced himself to calm down and read this book that did not fit his real age.

This book is too simple, there is no connotation, Conan holds the book with a small face, and the more he reads, the more he feels...

Seems pretty good?

Ahem...

..............................

Before you know it, it's evening.

It's been a while since the library closes, the library staff have disappeared from work on time, and the citizens who have come to borrow books have gone home in the twilight.

Because the make-up class was more dedicated, and the staff did not come to clear the venue when they got off work, Lin Xinyi and Mao Lilan have not left until now.

If they don't leave, Conan's classmates naturally don't dare to go first.

And just when he was lying on the table bored, silently counting the names of the various Ultramans and monsters that had almost been memorized by him, and passing the time out of boredom...

There was an eerie face, suddenly peeking out of the silence outside the door.

The head that poked in looked around, and soon locked its eyes on Lin Xinyi and the others who were still in the reading room.

Immediately afterward, a withered and thin figure walked through the door and slowly approached.

"Several... It's not early. ”

It was Conan who had been noticed suspicious by Conan at noon.,Director Tsukawa of this library.。

"It's past closing time, and I'm in a hurry to get home from work."

"If you like to read, you can register and borrow a book and read it at home."

Director Jinchuan smiled slightly at Lin Xinyi and the others, but the face with sparse hair, wrinkles, deep eye circles, and yellow wax was always a little crazy when he looked closely.

Especially under the illumination of the blood-colored afterglow of the sunset, this face looked more like a wandering ghost that came out of nowhere.

Not to mention, Director Tsukawa's voice is hoarse and ugly, low and weak, and it sounds more like a horror movie.

Mao Lilan, who has always been afraid of ghosts, got goosebumps slightly, but she still tried her best to put on a polite posture, and said to Director Tsugawa very embarrassed:

"I'm sorry, we've been here too long."

"I'm sorry for your trouble."

With that, Maolilan stood up and busied himself with his things.

She packed up her books, notes, pencils, and erasers, and helped clean up the eraser shavings on the desktop, before she got up and said to Lin Xinyi and Conan beside her:

"Mr. Lin, Conan, let's go back."

"Hmm." Lin Xinyi and Conan both nodded.

Then the three of them got up and left their seats and walked out the door.

But when passing by Director Tsugawa's side, Conan's brow couldn't help but furrow slightly.

He instinctively wanted to stop and take a closer look, but before this reasoning addiction could attack, he was picked up by Lin Xin one by one, and the whole person slipped out:

"Hurry up, don't be playful."

"I... Wait, I really think there's something wrong with him! Conan struggled in Lin Xinyi's arms with an ugly face, and whispered like this.

"Got it." Lin Xinyi ignored it completely.

Behind him, watching Lin Xinyi and the others go away, Director Tsukawa's expression was slightly soothed.

At this time, a call came to his mobile phone, and he was not afraid that Lin Xinyi and the others had not completely left, so he directly picked up the mobile phone and said in a calm tone:

"Don't rush."

"I'm all set, we'll meet right away."

Curator Tsugawa said something incomprehensible without a beginning or an end, and then he turned his head and walked out of the reading room and stepped onto the elevator upstairs.

Lin Xinyi and the three of them walked towards the door of the library from the opposite direction.

Maolilan looked natural, just a little tired from an afternoon of intensely focused study.

Conan's expression was strange, and his brows were furrowed.

He thought about it for a while, and finally couldn't hold back Lin Xinyi's collar, who was holding him away, and leaned into his ear and said:

"Lin, I really think there's something wrong with that guy."

"Did you smell it just now, there seems to be a faint sour smell on that Tsukawa curator."

"That smell... It's hard to describe, let me think about it... What the hell will it be..."

Conan frowned, pondering.

But Lin Xinyi suddenly replied: "That's the smell of tablets." ”

"Huh? Pills... Isn't that just—" Conan was slightly stunned.

"That's right..."

"Not only does that guy have a faint sour smell on his body, but he also has a pale face, weak breathing, and a slight bruise on the tips of his fingers."

"His eyes, in particular, are cloudy and their pupils are constricted and pinpoint-shaped."

"These are the symptoms that come after taking that diabolical drug because of the drop in blood pressure, the suppression of breathing and heart rate."

When he said this, Lin Xinyi's face was extremely heavy.

Moreover, there was a thick, irresolvable disgust in his eyes:

"With that kind of demonic drug, addicts are heating and smoking at first."

"But such a potion will quickly make the body resistant to the drug, and the same dose and inhalation method can no longer maintain the balance in the body, and it will not produce an effect."

"So, in order to maintain that guilty pleasure, the garbage will be uncontrollably injected intravenously to make the object more effective."

"But resistance will continue to grow... Over time, those guys who are not ghosts or ghosts, in order to find excitement, even dare to change intravenous injections to very dangerous arterial injections. ”

"Generally speaking, they will use a syringe to deliver medicine directly to the carotid artery, so that the object directly enters the brain with the arterial blood, which is an extremely dangerous behavior and can lead to sudden death at any time."

"Whoever comes this far, not even Jesus can keep him."

"Repeated intravenous injections can cause skin infections to fester, leaving ugly scars on the arms and wrists that cannot be erased; Carotid artery injections will also leave a visible needle hole in the neck. ”

"So, those disgusting guys who are mixed in the crowd, in order to hide their ugliness, don't dare to show their wrists and necks even on a hot day."

"In that case, why did that Tsugawa curator wear a suit in such a strange way..."

"The answer is conceivable."

Speaking these words with a calm face, Lin Xinyi couldn't help but let out a long sigh:

"I'm sorry, Conan, I didn't pay attention to what you said at noon..."

"That guy does have a problem, and it's a big problem"

"This Tsugawa curator is probably a long-addicted worm."
