The World seems Realistic but Why do I have a Leveling System?

When the students reported that they had heard a screaming in the hallways to the teacher they met on the way to the teacher's office, the teacher shrugged it off at first, thinking that they were trying to pull a prank on him. But he quickly realized that they weren't joking around upon looking at their frightened face.

Once he was very sure they weren't lying, the teacher immediately took off, heading toward the location as fast as he could. Unfortunately for him however, the moment he arrived on the scene, everything was already over.

But on the way there, he found a couple of students and asked them if they ever heard any scream, but surprisingly, they shook their head with a confused look on their face.

He then asked them the second questions, if they ever finds anything strange, to which they answer with, "Strange? Oh! A little while ago, there was a group of students where we walked passed them and I overheard their conversation a little bit. I thought they were talking about a game, but then one of them said they truly saw it with their own eyes!"

"A phoenix, he said! A real life phoenix! That's the most strangest things I have heard in my entire life!"

"Yeah, obviously that guy must be lying. A phoenix in this day and age? It can only exists in virtual world."

Just like his students, he wouldn't believe either if someone suddenly said they saw a mythical creature in a modern age, heck, he might ended up calling the ambulance, thinking the other party might be sick in the head.

When the teacher had properly inspected the whole scene and still couldn't find anything, he thought of quiting midway, but then he remembers the look on his students and decided to continue. Since the students said they heard a scream from the hallways, it is possible that whoever caused a scene had already left, or gone upstairs to the second floor. It's about fifty-fifty, but if it's the former, the students he passed previously would have seen, or came across them on their way out of the premise, however, they didn't.

As such, the teacher immediately ran toward the stairs. When he stepped onto the second floor, the teacher could faintly smells blood in the air which caused him to frown as bad feeling starts to kicks in. Without a second thought, he rush toward the nearest classroom and slide the door open.

No one was in the classroom and neither did the smell of blood, once he realized that, the teacher immediately went out to check the other classrooms. Room after rooms, he found nothing yet he could hear his heart beating loudly during the whole order as his thoughts starts running wild.

'There's a murderer in the premise! I have to find him first before he gets to the other students! Though I'm not really a fighter, at the very least, I can scream to attract attention and try my best to hold the murderer back while the help is on the way. Since the students only heard of scream but no gunshot, I think it's safe to assume the murderer didn't have a gun on him. With that in mind, I have a high chance to survive if I make use of the surrounding,' the teacher thought while he were observing the whole classroom befote leaving once he didn't find anything.

After some time, he stood silently in front of the last classroom as he thought, 'this has to be it. But why was it so quiet in there if there's a murderer? Did the murderer already killed everyone inside?!' the moment that thought passed through his head, the teacher quicky gathered all his courage and slide the door open.

When the teacher saw a group of students laid quietly on the floor, he gritted his teeth and immediately ran toward them while wishing they were just unconscious, not the eternal sleep known as death. He could only breathe a sigh of relief when he felt a pulse after checking each of their vital signs. However, he found the situation strange.

Why were they laying unconscious on the floor? One of them had blood on his torn shirt, however, there's no injuries when he look into it. Plus, it looks like the bloods had already been dried up while none was on the floor.

The second questions, where was the murderer? That is if it exists since it is nothing, but just an assumption on his part. However, if it's not a murderer, that raise another question.

'No, why not question these kids since they most likely holds more of solid information than something based on my useless assumption.' The teacher thought.

With a bit of shaking and few wake up calls, the students slowly awaken from their unconsciousness with a confused look on their faces as they haven't realized the situation just yet. Upon seeing their supposedly dead friend alive next to them, their memories before falling unconscious finally returned in full. Shock, fear, awe, and disbelief. Even without uttering any words, the teacher can clearly read the clear expression written on their face.

When they saw him, a teacher, was here, some of them obviously relaxed their tense shoulders followed by a sigh. If the teacher safely arrived here, that must means they have been rescued, or so they thought. When the teacher asked them of what happened, they quickly opened up and told the teacher the nightmare they just experienced.

Everything was fine until it gets to the part that one of the student were supposed to die from all the cruel beating he had received, yet for some unknown reasons, he still alive and no injuries on his body as if everything that happens was just a bad dream. They also told the teacher of what happened before they lost unconscious, but the latter is still doubtful whether they were speaking the truth of the matter.

After all, a student of his had once told him that they saw a phoenix, and now another student said a group of people hidden in cloaks were fighting with a single person when one of them died and suddenly, the single person disappeared and appeared below the two like a ghost before pulling the two down with it. Is this even real world anymore? Or is this just a dream he had due to overwork?

But he couldn't just denied it outright when all of them agreed that they witnessed the same thing. It's either all of them were lying to him, or everything they said is the truth. In normal case, he would have believe the former, but after a quick thinking, he realized their words might hold some truth in it. Either way, thankfully they were safe.

It was only later that the teacher learned that two of their students were missing. The last student that saw them in the hallways said he saw them walking toward the cafeteria, and there's three of them actually. When the teacher questions Luke, he appeared surprised when he learned two of his friends were missing, and he told them that he had to separated from them midway there since he needs to go to toilet.

Though the teachers were doubtful the truth of his words, they couldn't do anything since there was no proof that he actually did something. In the end, they called the cops and asked for their help. But few days passed, no clue was found and their location still remains unknown. Just when the parents of the missing students was about to give up on the search, the supposedly missing students suddenly appeared in their perspective's houses as if nothing happens to them.
