Mononobe Masao buried his head deeply and said in a low voice, "Yes, there is also Doctor Shinde... He died normally and has nothing to do with me..."

Conan looked at the bespectacled senior and felt that the expression on his face was more of one of self-blame.

His second sentence didn't seem like he was speaking to others, it was more like a self-comfort.

Qin Zhibo’s focus was on the first sentence, which explains why Belmode did not follow up to investigate the supernatural incident.

Because she couldn't know all the trivial things that happened two years ago, so she took the initiative to leave in order to avoid exposing her identity.

"Please all of you go out, I'm already very busy in order to catch up with this art exhibition..."

"Let's go! I don't want to waste any more time!"

Mononobe Masao suddenly stood up, shouted loudly, and yelled at several people to leave quickly.

After all, no one was killed and it was difficult to force them to stay, so the four of them had no choice but to leave.

Before leaving, Qin Zhibo glanced at the works on his easel.

It was a somewhat abstract, even weird painting, with a cloud of gray mist on top, and a slender figure vaguely visible in the chaos.

Are the paintings of high school students nowadays so unconventional?

After coming out of the art classroom, Mao Lilan and Yuanzi discussed whether they needed to consult Miss Tsukamoto Shumei.

At this moment, Conan took advantage of his height and discovered that the brick surface on the ground was somewhat reflective.

I knelt down and scraped it with my fingernail, and found that there was actually a thin layer of wax on the floor tiles.

Although I heard that in some places the cleaning staff will wax the floor in order to show the cleanliness of the floor, but this is a school and this should not be a habit.

Could it be related to the water on the stairs?

Conan lowered his head and stared at the ground, and Qin Zhibo also stared at Conan.

In the absence of investigation points, Conan is equivalent to a "literacy dog" who can eliminate all investigation blind spots that are not easily discovered by himself.

...

After the two girls discussed it, they decided to tell Tsukamoto Sumi, who was studying in the library, about the latest supernatural incident that had just happened.

"What? Are you telling the truth?"

Tsukamoto Sumi suddenly slapped the table and stood up, and other students in the library also turned their gazes here, staring at this side, the atmosphere was a bit strange.

Tsukamoto Sumi's expression was surprised and a little complicated at first, but she soon accepted it.

"Excuse me, don't you know the names of those books that Hideaki Hoita borrowed that are still in the library?"

Conan was determined to expose "someone's" prank and restore his innocence, so he investigated seriously.

Tsukamoto Sumi nodded, went to the library bookshelf, and found four books one by one.

Conan glanced at the four books on the table. They were all relatively obscure professional reference books, covering geography, history, industry, etc. They were not likely to be of interest to high school students.

When I opened the debit cards in the four books, there was only Hideaki Hoita's name on it, indicating that he was the only one who had borrowed these books in the past two years.

Tsukamoto Sumi explained with a smile: "His ambition is to be a cartoonist. He often says that in order to draw interesting cartoons, you must enrich your mind from various aspects..."

Qin Zhibo looked at Tsukamoto Sumi with a somewhat subtle expression.

As a warrior, Tsukamoto Sumi also felt Qin Zhibo's eyes, turned her head, and collided with Qin's eyes.

After the two looked at each other for a few seconds, Tsukamoto Sumi was the first to look away.

...

Not getting any useful clues from Tsukamoto Sumi, a few people went to the first floor again, wondering if they could find witnesses, maybe they saw the prankster directly.

But school has been out for a long time now, and there are almost no students on the first floor. Only when passing by the health room, I found that the lights inside were still on.

Opening the door, the Seko Kunushige whom I met before was lying on the bed by the window of the health room, with his arms resting on his head in a leisurely manner.

When he saw several people coming over again, he didn't have much surprise on his face, he just smiled and asked "What's the matter?"

Mao Lilan stepped forward and said politely: "Senior, we would like to ask you, have you seen any suspicious people on the playground just now?"

Shigu Guishan did not get up, he still rested his arms on his head and covered himself with the quilt, "I have been resting on the bed in the health room, and you can't see the situation on the playground here, right?"

He turned his eyes to the window, and saw a lush green plant blocking most of the window's view, and he could not see the situation on the playground.

How is this designed? The principal is really...

Just when Conan was complaining about his alma mater in his heart, a voice as majestic as the Z teaching office next to him suddenly spoke.
