"Xiaobai, I feel so happy." Ayumi looked at Maori Bai beside her and said as she walked up the stairs.

"Oh, what's wrong?" Mori Bai looked at Ayumi as if sensing something, and then looked at his feet.

"Look at it for yourself, you look like being a god like this." Ayumi stopped, then lifted her right foot, and then saw white gas under her feet follow the wind from which she lifted her foot, and then disappeared.

"What's the matter with these cigarettes?" Mitsuhiko shines his flashlight on the stairs while Conan runs up.

"Ah, blood, there's blood..."At this time, Motota, who was holding the handrail next to Mitsuhiko, called.

"Don't worry, it's not blood, it's just red paint, you see..."Conan finished speaking, and shone a flashlight on the handrail, the handrail of Didan Elementary School is made of stone, leaving only a little gap in the middle.

"That's... Tape." Mitsuhiko stepped forward and shone a flashlight as well.

"Well, it's just somebody letting the paint run down from this crack in the staircase, and if you put tape between the stairs, the paint will run down the handrail." Conan raised his hand and shone it on it, then on the tape on the armrest.

"And what's the deal with all these smokes?" Mitsuhiko asked, looking at the gas under his feet.

"It's just the result of putting dry ice in water for chemical experiments, which I found in the corner of the stairs." Conan said as he showed a cup, which was still bubbling white.

"So, this gangster is doing this to scare a few of us back?" Mitsuhiko thought for a moment and asked.

"Alright, let's go up there and get him arrested." Motota said excitedly.

"It's useless, the prisoner has already escaped, but I have my own way." Conan said with a smile.

"Ah, there's a ghost... It's scary... Hurry up, let's call together..."Conan shouted loudly, and then said to Yuanta and the others.

"That's what it is, creating the illusion that the prisoner thinks that we are afraid of running away, so that the prisoner can be brought out." Maori Bai pushed his glasses.

"Okay, since that's the case, it's so scary, there's a ghost..."I saw that Motota glanced at Mitsuhiko and Ayumi and screamed too.

"Alright, let's go, let's go hide." Mao Li Bai looked at the excited Yuan Tai and the others and said helplessly, and then walked towards the bathroom downstairs.

Half an hour later

"Conan, can we go out now?" Motota asked Conan.

"Well, that's fine." Conan pushed the door open and took his watch out of his pocket.

"Why is Uncle so slow, what are you doing?" Conan looked at his watch and thought speechlessly.

"Oh, don't look at it, I don't think he's coming, I guess he's already drunk and forgot everything." Maori Shiro, who came out of the bathroom, looked at Conan who was holding a watch to see the time and said.

"Heh... Conan seemed to agree, and then he seemed to think of something, and the corners of his mouth twitched.

"Hmm..."I saw Ayumi and the others looking at the other side of the window, as if they saw something terrible...

"What's wrong?" Conan asked.

"They're there, there's someone." Mitsuhiko looked at the other side and said

"They're all in our classrooms." Ayumi said and gestured to the classroom opposite.

"And it's not just one person." Motota also said.

"What? It looks like there should be a dozen people, what are they doing? In such a dark classroom. Also, the man seems to be wearing a mask, it's him, and Ayumi sees him. Strange, what is he holding?" Conan thought silently, and then saw that he seemed to think of something, trotted to the window, and crouched down.

"Where are you going? Conan." Motota watched Conan's movements and asked Conan with questions.

"Do you still need to ask about this, of course I'm going to catch the gangsters." Conan looked at Genta and the others with a triumphant smile, and then saw him bend over and start running towards the classroom.

Maori Bai looked at the other side, and then saw Conan and said to catch the gangsters, pushed his glasses, and jogged to follow.

"Will it be okay? Conan, can we really catch the gangsters?" Ayumi asked Conan as she ran.

Conan looked at Ayumi, raised his index finger, put it to his lips to indicate not to speak, and continued to run.

"Ahem." Soon coming to the classroom with the 1-B sign, Conan coughed, then knocked on the door, opened the door and went in, turned around and turned on the light.

"Look, this is the doll, and there's one on every table." Ayumi ran to her forehead and picked up the rag doll on the table.

"The plaster statues are all placed next to the window." Mitsuhiko looks at the plaster statue by the window.

"Even the mannequins are in this place, huh, what is this?" Motota said as he looked at the paper on the head of the mannequin placed in front of the blackboard at the back of the classroom.

"Parent-Teacher Conference." Mitsuhiko looked at the words on the note and read

"It's like a parent-teacher conference." Ayumi looked around and echoed.

"Yes, this person is the parents of the doll as a student, and then the plaster cast and the mannequin as the student, and he keeps practicing in the classroom every night, the purpose is to prepare for the parent-teacher meeting next week, and in order not to let others hear the voice, so he puts a mask on his mouth, am I right? The one hiding under the podium now is Mr. Kobayashi in the first grade B class." Conan spoke confidently as he reasoned and looked at the podium.

"It's really Mr. Kobayashi." Ayumi ran to the podium and looked at Mr. Kobayashi who was hiding under the podium.

I saw Mr. Kobayashi stand up from the podium and look at Conan and the others, and Ayumi also stepped forward to hug Mr. Kobayashi.But because of her size, she could only hold Mr. Kobayashi's thighs.

"So, the legend that the plaster cast changes its position and the running mannequin is..."Mitsuhiko seemed to think of it.

"Well, they're just moved here by the teacher every night, and as for the running mannequin, it's probably because she's running too fast, so it's wrong."

"But instead of doing exercises here, it would be nice to us students, wouldn't we?" Yuan Tai said with dissatisfaction.

"In other words, the teacher should change your nasty child's personality first." Mitsuhiko echoed the words.

"No, it's the opposite, the teacher just likes the student too much, so he doesn't know what to do, the teacher actually likes the student very much... I loved my students in my own way, and I didn't even lose my temper at that school before, but at the first parent-teacher meeting, I made a mess of things. The memories of the past came back to my eyes again, I couldn't sit or stand at all, I only secretly hid in this place every night and kept practicing. Mr. Kobayashi talks about his past while reminiscing.

"But now that everyone is afraid of me, and some people call me a tigress, it seems that I am probably not suitable to be a teacher." Mr. Kobayashi lowered his head and read.

"That's not the case," Ayumi replied as she stood aside.

"To be honest, I have known for a long time that Mr. Kobayashi is a very good teacher, this is what I have seen with my own eyes, after everyone returns home, the teacher sometimes helps to water the flowers in the classroom, or helps the fish in the fish tank to change the water, right?" Ayumi fell into a memory, looked at Kobayashi Sensei with a smile and said, then turned to look at Motota and the others.

"yes, because other teachers don't usually do that." People are also saying that it's strange that tigress can water flowers." Yuantai and Mitsuhiko said one by one, and when Yuantai in the back said the word tigress, Mitsuhiko gently touched Yuantai's stomach with his elbow.

"No matter what, no matter how much the teacher deceives himself, there is still no way to deceive the eyes of children, since the matter has been exposed, it would be better for you to restore your nature.

"I know that." Mr. Kobayashi replied with an embarrassed smile.

"But you're too much, teacher, how can you scare us with smoke and paint." Ayumi took Mr. Kobayashi's hand and said.

"Don't pretend, it's the teacher who hides by the window and peeks at us." Mitsuhiko echoed the words.

"What are you talking about? Today is the first time I've been practicing here, because when I heard Mitsuhiko-san's scream, I was so frightened that I moved the mannequin back to the health room, and I hid in the health room for the rest of the year." Mr. Kobayashi replied with a smile.

And Mao Libai, who was leaning against the door, listened to this sentence, the corners of his mouth rose slightly, and then walked into the classroom and stood next to him.

"Who opened the door to the faculty office?" Conan immediately asked when he heard Kobayashi-sensei's words.

"What are you talking about?" Mr. Kobayashi replied.

"Damn, that's true, there is another person besides Mr. Kobayashi." Conan thought as he ran towards the clerk's office...

"Where are you going? Looking at Conan who ran out, Mr. Kobayashi also ran to the door and called Conan.

"Alright, let's go along." Mao Ribai said to Ayumi and the others, and then also trotted towards the office of the staff.

"Don't move." When Conan came to the door of the faculty office, he said with a flashlight shining on the people inside.

"Dean of Studies, what's going on with your head." At this time, Kobayashi and the others, who rushed to the academic affairs room, looked at the whole picture illuminated by the white light, that is, the person in front of him and said.

"Mr. Kobayashi..."I saw that this person was 40 to 50 years old, with a bald head and a mustache.

"Hehehe... Hahaha..."And when Mr. Kobayashi and the others really looked at the person in front of them completely, holding back.Then, it seemed that they were holding back very hard, and the corners of their mouths glanced at them, and then they laughed.

Later, the dean of education told him the reason, it turned out that the person who wanted to scare Conan and the others home was the dean of education, and the reason why he came to school at night was just to find the wig that he had been blown by the wind in the faculty office two days ago.

"However, I searched for 2 days and couldn't find it." The dean said with a hint of sorrow.

"Dean of Studies, can't you just come like this?" Yuan Tai looked at the dean and said.

"No, no, no, I don't have the face to leave school without that wig." The dean hurriedly replied.

"Conan, I remember you said you met the Headmaster later, right?" Maori Bai asked Conan.

"Yes, I remember the headmaster saying at the time, "Paper can't keep the fire, this man's luck is so bad, it's all fate" Conan said, and then seemed to think of something.

"I guess the wig is at the headmaster's." Maori Bai looked at Conan, who had thought of something, and said his answer.

"Yes, that's it." Conan looked at Maori Bai and said, then spoke to the Dean of Students the same answer he had asked the Headmaster the Dean of Students during the day.

"Alright, Dean of Studies, we'll ask the Headmaster tomorrow, it's getting late." Mao Libai said to the dean.

"Yes, Dean of Students, the students are tired too." Kobayashi sensei looked at Ayumi and the others.

"Well, I'll leave it to you tomorrow." The dean said to Conan and the others.

"But, Dean Student, you're going too far to scare us with smoke and paint." Yuan Tai seemed to think of something, and said to the dean.

"Ah, you all found out? The Dean of Education said with consternation.

"Hmph, you're underestimating us, we're a junior detective team...," said Yuantai.

"yes, the Dean of Education is excessive." Mitsuhiko and Ayumi also chimed in.

"Hehe, that's really sorry...", the dean was embarrassed, and then bent down to apologize to them...

"Hehe, hahahahaha..."Looking at the bald head of the teaching director, Ayumi and the others laughed heartily again...

That's it... We spent the day smiling, and this day was the first day Maori Bai spent on campus.

On the second day of class, Ms. Kobayashi became much gentler, and her classmates said that they changed quickly, and because of this, as time went by, the students in the class liked her.

And about the dean, as Conan guessed, it turned out that the principal hid the dean's wig, and the principal returned the dean's wig to us, so we could apologize to the dean.

And this school rumor was solved in this way.
