5:40 p.m. in the Faculty Building.

In the conference room, as the muffled thunder sounded outside, a group of teachers instinctively looked out the window.

In the window position, Judy raised her neck to look at the sky, then swept her eyes down, and saw several figures in the corridor of the opposite teaching building, and couldn't help but be slightly stunned: "That's ...... The new doctor, and Xiaolan, Yuanzi, Yunwen, and that weird and intelligent Conan? What are they doing at school?"

Judy thought for a moment, then suddenly shook her head and withdrew her gaze, "No matter! But the new doctor has just returned to school, and is he mixed with the students?"

"I didn't expect that his popularity is quite good......"

......

Didan High School, School Building.

The library is on the third floor of the main building. Shu Yunwen, Tsukamoto Shumi, Conan, and Xiaolan chatted and walked, and soon walked into the corridor of the main building, and were about to walk towards the stairs, when suddenly they heard the sound of the door closing.

Shu Yunwen and they were all stunned, and when they turned their heads to look at the voice, they saw a boy walking out of the men's bathroom.

Seeing the boy, Tsukamoto Shumei let out a "ahhhh

At the door of the bathroom, Shigu Kunifan was stunned for a moment when he heard Tsukamoto Shumei's voice, and turned his head to look at it with a surprised face: "Tsukamoto-san? and Shu-san......? Investigating paranormal events together?"

"That's right!" Tsukamoto nodded and smiled, "...... Speaking of which, I heard you say that you weren't feeling well at noon, and I thought you were going home now!~"

"This one...... I was going to sleep until I got home from school, but I just woke up and it happened to be raining. Although I have an umbrella with me, I don't want to go home in the rain, so I plan to go to the health room to rest for a while, and then go home when the rain stops......" Shigu Kunishi said, yawning and said, "Okay, Tsukamoto-san, let's not talk, I'll go to the health room to rest first, if you find out who is playing a prank, remember to tell me......"

"Okay. Tsukamoto nodded and moved her wrist and said, "...... When I find that guy, I'll definitely give him some colors to see!Also, Xiaolan, you have to help!~"

Shumi Tsukamoto applied to Xiaolan to form a team to beat people, and Xiaolan laughed dryly and said, "...... I think...... Sister Shumei, you're enough for one person......"

In other words, Sister Shumei, you alone are enough to overturn a taekwondo club, just an ordinary person, and you still need to find me to form a team?

You don't want to beat that person to death and drag me along with you, do you?

Xiao Lan thought in her heart, Shu Yunwen and the others also said goodbye to Shi Gu Guofan, walked up the stairs, and soon walked into the library.

In the library, some good students who are addicted to learning and can't extricate themselves are lying on the table reading books and doing problems, and occasionally someone looks up, and after seeing Tsukamoto Shumei and them, they will think about Tsukamoto Shumei waving his hand, and Tsukamoto Shumei also smiled and saluted back.

Looking at this scene, Yuan Zi said "ah": "Sister Shumei, you know so many people in the library!"

"yes!" Tsukamoto nodded and smiled, "...... After all, I used to be one of them, and in order to get into college, I often read and study here after school, and I didn't come much until Yun Wenjun woke up......"

"Uh......" Shu Yunwen was a little speechless when he heard this-

Shumi-chan, do you want to say that we have influenced your studies?

As for the garden, she grinned and teased: "After Lord Yunwen wakes up, Sister Shumei won't have time to study? Sure enough, this is the power of love...... But if you want me to say, you don't need to study, Sister Shumei, you can marry Lord Yunwen in the future and be a happy full-time wife......"

"I hate it! Garden!" Tsukamoto Shumi was a little shy, and gently patted Yuanzi's shoulder, Yuanzi only felt that his shoulders hurt and his feet were weak, and half of his blood was lost, and the corners of his mouth twitched twice, and he looked at Tsukamoto Shumei with resentment-

Anyway, let's just make a joke, Sister Shumei, are you trying to break me?

The garden was a little resentful, and Conan coughed lightly beside him, "...... By the way, Sister Shumei, what is the supernatural event happening here in the library?"

"Well, the so-called supernatural event is nothing more than four books that Hideaki Hosaka had read before, and they were thrown in the library indiscriminately, and these were all discovered early in the morning......" Shumi Tsukamoto replied, and Sonoko was resurrected with full blood, adding excitedly: "...... No, it's not that simple! You know, this kind of thing happened for four days in a row! Four days! The students are spreading among themselves, this is because Hideaki Hosaka can't read these books anymore, so the regret is hard to get rid of, and he has become a ghost and later vented his anger here......

The garden's voice became louder and louder, attracting the attention of the students around who were obsessed with learning and couldn't extricate themselves, Tsukamoto Shumi and Xiaolan hurriedly gave the garden a silent gesture, and Conan asked curiously:

"Sister Xiaolan, will the school's library be locked when it's closed?"

"Of course!~" Xiaolan nodded, and Conan continued: "In this way, assuming that all this is man-made, those books that were found to be discarded indiscriminately in the 'early morning' should have been taken out before the library closed the day before, right?

"This one...... I've heard that those four books seem to have been thrown behind the shelves or under the desks or something, and it's not easy to see......" Xiaolan replied.

"That's right!" Conan suddenly realized, "Then this is not a supernatural event at all, it is just someone playing a prank, right?"

"Uh...... That's right!" Xiaolan nodded in agreement, and the garden crossed her waist on a plate, and pouted unhappily—

In other words, investigating supernatural events with these people is really boring, and the feeling of horror is not ......

Yuan Zi muttered in his heart, and Conan suddenly asked, "By the way, Sister Xiaolan, what are the names of the four books that Hideaki Hosaka has read?"

"Huh, how do I know this......" Xiaolan didn't finish speaking, and Tsukamoto Shumei next to her suddenly said: "...... The four books are "History of the University System," "Report on Rainforest Destruction," "Analysis of the Sound of Rock Destruction," and "Theory of Electrical and Communication Engineering," ......."

"Huh, what kind of books are these! It sounds ......like a big head," Sonoko said his head was a little dizzy, and Tsukamoto Shumi smiled:

"Yes, these books are quite off-the-beaten. However, Hideaki Hosaka seems to have said that in order to become a good manga artist, you must constantly enrich yourself and learn many things that others do not know...... Also, as I recall, none of these books have been borrowed by anyone other than Hideaki Hosaka......"

"I see!" Conan couldn't help but smile when he heard this, and stretched out his hand to pull Shu Yunwen in a daze:

"Brother Yunwen, you must have thought of it too, right?"
