After some examination, Fujiwara Yo was sure that none of them were lying, because they had all been contacted by the same landline, so they were invited here by the same person, and that person was most likely behind the hidden somewhere.

Now only Ruriko Sakuragi is contacted by Makoto Makoto, who disappeared, which doesn't rule out her suspicion, maybe this is a self-directed and self-acting, taking the initiative to find herself, but also to get rid of suspicion.

Fujiwara Yu looked at the computer screen in silence, he thought of the phone calls received by several other people, and was about to ask, when there were footsteps at the door, and before he could see anyone, he heard an extremely loud voice: "Hey, hey, hey!" Who the hell came here so late without permission, please don't increase the workload of our guards at will, okay?! The man who appeared at the door with a flashlight had gray hair, and he looked to be no more than fifty years old.

He looked at the people in the classroom unhappily, but when his eyes swept over Sousuke Taji, he was stunned. He quickly stepped forward and looked at it carefully, his attitude improved, and he asked aloud, "Huh?" You're the Eagle Officer who came to school in the morning, right? Why did you bring your students here so late? ”

"I'm sorry, we came here after receiving a call from a student, and there are strange words written on the computer over there, and the student who is calling now has disappeared, so I want to investigate in this old school building." Fujiwara Yu politely explained, not dissatisfied with the other party's previous yelling.

The gray-haired guard couldn't help but be stunned when he heard this, he walked to the computer screen, and after seeing the content on it, his face became a little ugly, and he turned around and asked, "This is the payment...... Isn't there really some curse? ”

"Mr. Guard, there is no curse in this world, if you are afraid, I can find a student to help me lead the way." The gray-haired guard hurriedly waved his hand, and he introduced himself with a smile: "No, I'm not afraid, oh yes, I forgot to introduce myself to Mr. Sergeant, I'm Tachibana Ryozo, who works as a security guard at Teidan High School, and is mainly responsible for patrolling, so I'm familiar with every part of the school." Fujiwara struggled for a while, and finally took the other students to the school building that was in use, where there was a guardhouse, just enough for them to rest.

Before leaving, he didn't forget to give Sakura Ruriko his contact information, just in case he received another strange phone call, he could contact him as soon as possible.

After Tachibana Ryozo gave a flashlight to Sosuke Takaji, he said loudly, "Officer Takaji, where are you going?" ”

"Where is the biology room that doesn't open the door? I'm going to check it out there. Fujiwara raised his watch and looked at the time, it was twenty-two o'clock in two minutes, and he still cared about the phone calls received by the other students.

What exactly does a death ritual mean? Just pure mischief...... Or is it a murder teaser? Tachibana Ryozo knew where Sosuke Takaji was going after a little thought, and he said with a smile, "The biology room that doesn't open the door? Oh, you said the abandoned biology classroom, the classroom is on the second floor of the old school building, come with me. ”

"Well, I'm sorry for you." Fujiwara Yoshi followed Tachibana with a flashlight, and he remembered the clues he found during the day's investigation, and asked aloud, "Mr. Tachibana, I remember that the old school building will be demolished next month, right?" ”

"That's right, but I don't know what's going on, there are still people who oppose the demolition, it's that threatening letter, you have also seen it, Officer Eagle Division, right? No matter how you look at it, it means opposing demolition, and I don't know what that person thinks. ”

"Did anyone openly object to that?" Tachibana Ryozo shook his head after a moment's thought, and he said with a smile: "No, but there are one or two teachers who are more worried about what will happen to the school, they think that the content of the threatening letter is true, and if it is demolished, something bad will happen, and now it seems that they may not be blinded by them." Fujiwara Yu nodded thoughtfully, he was about to follow when he noticed a light coming from the old school building opposite, he stopped in confusion and asked aloud, "Mr. Tachibana, is there still anyone using the classroom on the second floor opposite?" ”

"Huh?" Tachibana Ryozo narrowed his eyes and looked at the bright window on the opposite side, touched his head and wondered: "It's strange, I patrolled the second floor just now, and I obviously turned off the lights in the corridor, and the one at the end is the 'creature room that doesn't open the door', and it is impossible for light to shine through from it!" "A biology room that doesn't open the door?

Fujiwara Yu immediately propped his hands on the edge of the window, trying to see the situation in the classroom opposite, but he saw a shocking picture - the person hanging from the ceiling was Makoto Makoto who had disappeared for a long time!

Just as he was about to rush directly to the old school building, a thing in a black cloak moved in front of the body, and the other party slowly turned around as if sensing that someone was paying attention to him.

The silver-gray straw-like long untreated hair, the terrifying dark red face, and the round eyes seemed to be staring into the abyss...... Isn't this what humans look like, is it a mask?

No, now is not the time to think about that. Fujiwara Yu took a step and rushed downstairs, all the way to the end of the second floor of the old school building, and when he twisted the doorknob hard, he found that the door was locked.

He looked at Tachibana Ryozo, who was panting and followed, and shouted, "Hurry up and take out the key and open the door!" ”

"Whew... But...... This biological room can't be opened at all, and there is no key at all! Tachibana Ryozo put his hands on his knees and gasped for breath, he really couldn't breathe after running for so long without exercising.

Without a key, how did the murderer open the door? Isn't this the second floor? Although Fujiwara Yu had doubts in his heart, but now he couldn't care about so much, he directly raised his foot and kicked towards the door, the old wooden door fell to the ground in response, stirring up the old ash, if it wasn't for the power of the wind to protect his mouth and nose, it is estimated that he would be like Tachibana Ryozo behind him, choking and coughing.

He looked up at the ceiling, only to find that the entire biology classroom was empty, whether it was the masked freak in a black cloak or Makoto Makoto hanging from the ceiling...... It's all gone without a trace.

"How is that possible!"

"No one?! I saw it with my own eyes, how could there be no one?! Tachibana Ryozo, who had managed to recover, was incredulous, rubbing his eyes vigorously and telling himself that he wasn't dreaming.

Da-da-da-da. There was a sound of hurried footsteps outside the house, and Fujiwara Yu turned back vigilantly, and when he saw the girl who appeared in front of him, he was surprised, "Why are you here?" ”
