The nursery school is small, with only four classes.

The school building is mainly two teaching buildings, one large and one small, like a refrigerator stuffed by housewives, which is neatly and fully arranged with children's classrooms, indoor activity rooms, lunch break dormitories, small canteens, infirmaries, and teachers' offices. All windows are fitted with fence-like protective fences to prevent children from falling during the climb.

In addition to the two school buildings, there is a playground connected to the play space, and a bell tower at the end of the playground that echoes the main building.

Not to mention the bell tower where the blue peep is, in the teaching area of the school, because the equipment is for children, the school from the tables, chairs, equipment to the interior space are designed to be extremely small, if adults walk through it, there is really a sense of dislocation in a parallel world.

Probably for safety reasons, there is no area for Pokémon to be stocked in the school, even Pokémon that are close to people like dolls and Miss Skirt are not allowed, and only teachers who specialize in teaching elf knowledge can bring one or two Pokémon into the school during the teaching period.

"It doesn't look like there are wild Pokémon lurking everywhere."

At the back of the school building, Bilan hides behind the shade of a tree, cleverly avoiding the sight of passing teachers while her face is thoughtful.

According to Dr. Ohki, the hypothesis of mental illness and spatial wormholes is basically impossible to hold, and the reason is similar to what Bilan once reasoned -

Mental illness cannot affect anyone other than the patient, and there must be another reason for Sachiko's intermittent disappearance in school; Scientific theories also do not support the natural formation of space-time rifts by chance, perhaps in the vast universe of light-year units and in the microscopic world under the quantum microscope, there may be one or two such wormhole wonders, but in the reality that can be perceived by the naked eye, such accidents do not exist.

Even if it exists, it can only be caused by Pokémon.

"Hmm...... In a sense, the existence of some Pokémon is essentially a figurative embodiment of the concept of the supernatural. ”

Last night, or in the afternoon of the Kanto region, an authority on the Pokémon research community said this on the phone.

"Superpowered elves such as Casey embody teleportation and telekinesis, and the ghost system represented by ghosts realizes possession and wall piercing; In the same way, Pokébi represents good luck, the unknown totem interprets the unknown, the unicorn interprets the weird, the shadow doll holds resentment, and the Grim Reaper's coffin seals the ghost, and the Olup mimics the UFO...... Pokémon fill the sky, sea, and earth like air, so that there is no such thing as the unthinkable in the world, and all the unknowns seem to be answered by Pokémon.

"Some modern Pokémon scholars even believe that it is precisely because there are fantasies about unknown concepts in human hearts that the corresponding Pokémon appear one after another. And as the opposite of this phenomenon, it is precisely because of the appearance of these Pokémon that the supernatural fantasy in the true sense is dissolved, miracles, ghosts, resentful spirits, monsters, aliens, unknowns...... They were supposed to be more commonly seen in the world, but their place was taken by Pokémon with the same elements, so they had nowhere to be found in the real world and turned into nothingness.

Of course, this is only the conjecture of those scholars, and it is far from the truth of the world. The modern view is that this theory is imbued with anthropocentric idealism, and evidence against it is emerging, most notably the ghosts that are often seen in the town of Guandu Shion...... However, even if the theory is wrong, the argument they put forward is unequivocal - if Pokémon are considered part of nature, more than 99% of the supernatural phenomena in the human eye are caused by Pokémon after deep study. ”

The strange phenomenon on this campus is probably within 99 percent.

Strip away the situation outside the school, eliminate hypotheses such as staggered time and space, and there is only one problem left that really needs to be faced-

How did Sachiko disappear in an instant and leave a memory different from everyone else's?

When it comes to Pokémon's method of making a little girl disappear in an instant, the first thing that comes to mind should be the "teleportation" move that can lead people to transfer spatial positions; When it comes to making children have false hallucinations of traveling through parallel worlds, it is impossible not to mention the superpower moves represented by "hypnosis".

If the two are combined, if only the possibility of a crime is considered, if this case takes place in the Guandu area, people will undoubtedly point their suspicions at superpowered elves such as Yongjira and Dream Tapir.

However, this raises new questions - the kindergarten class is an extremely closed space, the teacher is always supervising the children on the premise that they will run around, and the students will pay attention to each other's situation.

Even if the Pokémon just flashes away in the class with "teleportation", it is very likely to be witnessed by the surrounding children and the supervising teachers, how did that Pokémon quietly take away the girl?

Take, for example, what I observed in the morning, when all the children in the class were playing in the playground, with at least two preschool teachers supervising them, and Sachiko was accosted by a little boy by her side. Bilan couldn't imagine how the girl would disappear under such strict surveillance.

In addition, there is no possibility that the elves will take Sachiko alone while she is in the toilet, because in the nursery school, the teacher will organize the boys and girls to go to the bathroom in batches at a fixed time...... This is how children go to the toilet in kindergarten schools, otherwise they will easily pee their pants without a sense of time.

When she observed this scene, she felt as if she had been hit by "100,000 volts", "Ah, that's really the case", and so ashamedly recalled the fragment of the message before the memory.

Is it possible that the Pokémon clings to the ground of the underground garage and takes the children on the ground to "teleport"?

Seeing the underground garage next to the entrance of the campus, Miss Detective Acting couldn't help but think actively.

Although it is not in the core area of Feiyun City, the land price is still expensive, and the land utilization rate must also be taken into account in the design. Therefore, the place where the teachers park is located under the playground, and if the isolation between the basement and the playground is not thick enough, the troublesome Pokémon can use the underground space to perform teleportation tricks.

"Well, it's really necessary to investigate the underground." The girl, who had already thoroughly investigated the structure of the school, thought.

However, the entrance to the garage is guarded by a security guard, and the playground is nearby, and the view is extraordinarily wide, and it is impossible to sneak in. Even if you sneak in, how to measure the thickness of the isolation is also a problem, if only the Geng ghost who can stealthily penetrate the wall is there at this time, and the Changeling Monster who only "transforms" with the impression can't do this kind of thing.

But it's not impossible to rely on herself, and it took two seconds for Azur to come up with a coping strategy-

It would be nice to enter the school as a relative of the client at the end of school.

The phone's built-in GPS can also show the altitude, which can be concluded by subtracting the height of the space in the basement.

So, under the cover of slides and swings, Blue walked through the playground again, into the small hall inside the bell tower, through the old and steep staircase, and climbed to the top of the bell tower.

"Speaking of which, the bell tower looks much older than the school, and the stairs are so high that they can't be for children. Was it a building that existed before the school was built? ”

As she prepares to glide away on the Vulture turned Condor, a flash of inspiration flashes through her mind before jumping off the bell tower.

It was as if the clues to solve the case had been completely prepared, and he was only half a step away from the truth.
