"That's all for today's lesson."

The teacher closed the lesson plan in his hand and jumped down from the small bench.

"It's as short as the teacher's height."

"I thought the person had disappeared suddenly, but it was just blocked by the podium."

"Kill you!"

The whispers from below obviously gave her a lot of stimulation, and when she jumped up and brandished chalk to give a head-on blow to the bad guys who dared to provoke the majesty of the teacher, Li Wu put up the textbook to cover his face, leaned over to the adjacent table and whispered, "Why is she still like this?" ”

"Maybe it really can't be changed back, maybe the middle-aged uncle's wish is really terrible."

Hoshikawa Aoi also responded in a low voice, "We'll know what the situation is when we break the fourth seal today." ”

The current Chiyo City is almost exactly the same as its original state, and no one has even noticed the existence of Demon King City, and the same is true when it comes to the Quadruple Seal.

And after a night's rest, they set their sights on the last seal.

Char, who sent a clone to attack the light yesterday, didn't make any more moths, as if he really incarnated as the final boss who was obediently waiting for the brave to come to the door, waiting for the assembled people to push him down.

"Speaking of which, I was taken away directly by Shiratori-san yesterday, what did you do later?"

She asked casually.

Li Wu's ability to summarize has improved a lot recently: "I wiped my face with Help." ”

Hoshikawa looked at him suspiciously for a moment, and did not withdraw his gaze until the teacher on the podium who had fallen into a disadvantage ran out of the classroom on his short legs in anger.

"Let's get ready to go, too."

Eventually, she just said that.

Because of the distorted relationship that has been gradually corrected, the fandom will not act as unscrupulously as it was in the days of the Brave Ministry, and the group chose to meet in the corner of the campus and then rely on Shiratori's ability to bring them to the Fourth Seal one by one.

"From a close distance, it looks like a castle floating in the air or built on top of a mountain."

Hoshikawa Aoi unfolded her wings of light for flight, trying to reach the black cloud that shrouded everyone's heads, but she passed through the thick walls like a phantom.

"I can't see the boundaries of space that I can cross...... Do you want to go up from the school building? ”

After she landed, Shiratori Maki was the first to walk into the empty junior high school teaching building, followed by Li Wu and Hikatsu, who had revisited their alma mater, with some nostalgic feelings, and finally Airisa and Hoshikawa Aoi.

Walking up the stairs to the second floor, you will see dusty classroom window frames, neatly arranged chairs, and a blackboard with neat handwriting......

Except that there were no students, it was as if nothing had changed—after all, it had only been less than a year since they entered Inaba High School.

"Although, nothing good happened, but I was very happy when I was here with Xiao Wu."

Hikari quietly stretched out his hand, and was grabbed by Aoi Hoshikawa, who squeezed over halfway.

The two of them holding hands crossed directly to the front of the line and climbed the stairs leading to the third floor, and Li Wu didn't even have time to make any answers.

Why did the enemy choose this as a stronghold?

What exactly Char has to do with them, and where does his obsession with killing the light come from—there's a hunch that the answer will be revealed right away.

“…… Hey? ”

Hoshikawa Aoi's stunned voice came from behind.

She had just run up to the third floor with Hikari, and walked up the stairs below to the second floor where they had been, and took a look at the remaining three.

"Don't go up yet."

Li Wu grabbed Airisa, who was almost following them, "Can Shiratori see anything?" ”

The phenomenon in front of him reminded him of the Penrose Ladder, which can only exist in the flat world, a geometric configuration proposed by mathematicians that can only be established by ignoring the concept of height in three-dimensional space, and manifests itself in the form of a circular staircase.

And they happen to have a spatial ability.

Shiratori's figure flickered a few points of light like an old-fashioned TV screen with a bad signal, and then disappeared in place.

The next moment, she reappeared after a few centimeters offset, and her face was much more ugly.

"Everything was normal before, but when I used my ability just now, I noticed that the spatial boundaries here suddenly became a mess...... No, it should always have been, but I didn't notice it. ”

She glanced at Li Wu, "For example, it's like unwittingly breaking into a tunnel that was deliberately built into a maze during the passage of the subway, sorry, if only I had used the ability earlier." ”

Shiratori bit her lip in remorse, this was the first time she had suffered in this regard since she had gained her superpowers.

"You said you sensed that the other party was summoned from another world using the same power as you, right? It is also normal to have a defense in this regard. ”

I feel more and more that there is some conspiracy behind the Song Project that caused the other party to awaken superpowers...... But now we have to deal with the issues at hand.

Li Wu turned to the little vampire while thinking: "Erisa, can I ask you to go up and give it a try?" ”

"You think this is a mechanism for screening?"

Hoshikawa Aoi reacted immediately.

If it was to divide the party or send the person who went upstairs into a trap, there was no need to let her go back to where she was, and the light was gone.

It's more like the kind of obstacle they encounter when they first join hands to fight the Hyakki Night Walk that allows a specific person to pass.

Considering that Shiratori Maoi's ability was disturbed in the environment specially arranged by the other party, Hoshikawa Aoi had already tried it again, and then it was naturally the turn of Airisa, who had the ability to protect herself even if she stepped into the trap, and even if she disappeared, there would still be two main combat forces left on their side.

She obediently ran up, then circled up from below like a magical girl, and froze for a moment when she saw everyone, as if she couldn't figure out how she had managed to get back to her place.

“…… It's my turn. ”

Li Wu wasn't so surprised when he saw Erisha return to her place.

He already had a vague premonition of who this obstacle in front of him really wanted to screen - along the way, there was still light in him, and there was already a strong karma entwined between him and the mastermind behind the scenes.

The otherwise quiet corridor suddenly sounded with an unpleasant roar that sounded like the sound of scraping a blackboard ten thousand times with sharp fingernails, and from the empty classroom poured out of the empty classroom, unspeakable monsters, flying sarcomas, eyes connected to tentacles, walking with human hands, and black-haired spine......

"Monster of the Negative Realm!"

Almost instinctively, Hoshikawa Aoi switched to a combat state, and Ping raised his magic weapon and fired a standard magic cannon towards the end of the corridor.

A torrent of white washed by, leaving a sticky trail of blood that rippled in a rainbow on the walls.

The entire school building seems to have turned into an otherworldly demon realm, unleashing a sinister aura to the unfortunate ones who invade it.

"So the trap is set up here? Li Wujun will go up first, and I'll leave it to them here. ”

Shiratori was indeed startled by the monster he had never seen at first, but quickly calmed down.

Although it is said that it is handed over to them, not to me, this is worth complaining about.

"It's like the first time I met Hoshikawa, but I'm sorry for you!"

The magical girl who fights with the monsters in the hallway of the school building takes the time to compare scissorhands, as if she is competing with someone who is not there, and Airi Sago has completed her half-dragon form in front of the weakened white bird.

Li Wu swung his fist and blasted several negative realm monsters that stood in front of him, and stepped onto the stairs leading to the top floor.
