Refuse to allow Conan to join the main storyline

"Murakami-sensei, she's not here. Maybe she went to the classroom?"

"Mr. Murakami? I think I saw her going to the infirmary just now."

"Not here, I don't know where she went."

Kudo Shinichi was almost going crazy.

He was clearly in the school, but he couldn't find her. Why? He took Xiaoquan and ran around the school, but he didn't find her for half an hour.

Finally, it was Koizumi who suggested, "Why don't we go to the art classroom and take a look? If we can't find it, we can forget about it today."

As she spoke, she glanced upstairs.

There was a faint stench coming from that direction, almost the same as the one she had smelled at Xiaoshen's house just now.

Little Kudo didn't notice the changing look of the man next to him: "Well, if I can't find it again, I'll go back!"

"Yeah, no problem."

The two of them went upstairs and came to the outside of a classroom. Before they opened the door, Koizumi could already hear some noise inside, the sound of stones rubbing against the ground. Not only that, but there was also a strong stench coming from the room.

Koizumi became alert and subconsciously reached out to open the door before Kudo Shinichi. But even though she used a lot of strength, the door did not open. It was obviously locked from the inside.

"what?"

Kudo Shinichi also tried to open the door but failed, so he slapped the door and shouted, "Murakami-sensei, are you in there?"

A woman's alert voice came from the classroom: "Who is it?"

"I'm Kudo Shinichi!"

The woman's voice was surprised: "Kudou-san? Wait a moment, the teacher will open the door soon."

The sound of stones rubbing against the ground, the sound of an easel being moved, and the sound of hurried footsteps.

With a "click", the classroom door was opened.

Kudo Shinichi peeked into the classroom and asked, "Murakami, what are you doing? Why are you locking the door?"

"Sorry, the teacher is concentrating on drawing. I locked the door because I don't want to be disturbed." The woman said with a smile, looking at Koizumi standing at the door with a puzzled look, "Excuse me, who are you?"

Koizumi came up to her and held out his hand: "Murakami Kumi-sensei? Hello, my name is Sakurai Izumi, and I asked Kudo-chan to come look for you."

What puzzled Koizumi was that this woman clearly had a faint floral scent on her body. If she hadn't deliberately moved closer, this scent would have been almost completely drowned out by the stench in the room.

The special smell on her body was not stinky at all, but came from somewhere in the classroom.

Just like in the photo, Mr. Murakami is not tall, has a childish face and clear eyes, and does not look like a criminal at all.

She couldn't help but hold the hand that Koizumi extended to her: "Ah, hello, Ms. Sakurai. What can I do for you?"

Koizumi didn't answer. She looked down at Kudo Shinichi beside her. The guy was still looking around trying to find something wrong in the room.

Koizumi reached out and patted him on the head: "What are you looking at?"

Kudo Shinichi rolled his eyes at her in dissatisfaction: "I'm looking for teacher's paintings. Didn't teacher Murakami say she was painting?"

Koizumi noticed that the woman's expression was a little unnatural, so he pointed to a draft on an easel not far away and said to help her out: "Isn't that it?"

"Eh? But that draft has been here for a long time."

Without waiting for Mr. Murakami to explain, Koizumi said, "What do you know, you little brat? The draft must be perfect, otherwise how can the final work be good?"

"Oh, is that so?" Kudo Shinichi looked puzzled.

Primary school students are so easy to fool.

Koizumi complained in his heart and pushed him out the door: "Okay, aren't you in a hurry to go back and read the novel? Go back quickly!"

"Eh? Eh?"

With a "bang", the classroom door closed behind Kudo Shinichi.

Little Kudo scratched his head in confusion, but in the end his eagerness to read the novel prevailed and he walked away with big strides.

Hearing the footsteps outside the door gradually fading away, Koizumi finally moved his ears away from the door.

Of course, she didn't need to do this to hear clearly what was happening outside. She did this all for Mr. Murakami behind her to see.

Teacher Murakami was a little nervous. She subconsciously glanced at the row of plaster statues at the back of the classroom and asked Koizumi, "Excuse me, what do you want?"

Koizumi smiled at her gently: "Please allow me to introduce myself again. Hello, my name is Sakurai Izumi, and I'm a detective."

"Detective!" Teacher Murakami's expression immediately became panic. She couldn't help but look in the direction of the plaster statue again, and said calmly, "Excuse me, what do you want to talk to me about?"

"I told Kudo-chan that I wanted you to design a new logo for my firm."

Mr. Murakami breathed a sigh of relief: "Oh, I see."

Koizumi sighed and shook his head, "That's just a way to coax a child. Mr. Murakami, you are so innocent that you really shouldn't be exposed to those dirty things. There's still time, call the police."

Murakami Kumi's face turned pale instantly, and her whole body began to tremble uncontrollably, but she still gritted her teeth and argued fiercely: "I, I don't know, I don't know what you are talking about!"

Koizumi sighed and walked to the row of plaster statues under her gaze.

The stench became more pronounced.

Koizumi turned his head to look at the pale Murakami Kumi, and made sure that she had no intention of drawing a weapon to attack him. He reached out and knocked down a plaster statue, and took out a bag of white powder from it.

"Murakami-sensei, please explain to me what this is?"

Kumi Murakami looked like she was short of breath and was about to faint. She covered her chest and slowly sat down on the ground.

Koizumi sighed, put the bag of white powder back to its place, and put the plaster statue back in place. Then he walked to Murakami Kumi, reached out and helped her sit down on the chair.

Seeing Koizumi's series of actions, Murakami Kumi asked hopefully, "Can you keep it a secret for me?"

Koizumi shook his head: "Murakami-sensei, what clues do you think I used to find you? If I hadn't made sure that you were still clean and hadn't touched that thing, you would be a corpse now. You don't know how dangerous your situation is!"

Facing Koizumi's increasingly dangerous eyes, Murakami Kumi showed an expression of fear on her face, and curled up like a quail and began to tremble.

"You'd better tell the truth. Whose are these things?"

"Yes, it's my boyfriend Takashi..." Murakami Kumi said tremblingly, "These are the drugs he resells, just some ordinary drugs for treating neurasthenia. I advised him not to do such illegal things. He, he didn't listen to me..."

Koizumi frowned, "Medicine? Just medicine? That's what he told you?"

"Yes, what's the problem?"

Koizumi was almost laughing out of anger: "Oh my god, this is unbelievable! You just believe what he said? Do you have any common sense? Where's your brain!"

Murakami Kumi was a little confused by Koizumi's scolding. She looked at her with a pair of innocent big eyes: "It's not medicine? What is it?"

Before Koizumi had time to explain, the classroom door was opened from the outside again.

Kudo Shinichi pushed the door open and walked in: "Murakami teacher, someone is here to see you again!"

When Murakami Kumi saw the man standing at the door, her expression suddenly changed: "Takashi, Takashi!"
