Rei stepped outside of the room and glanced left to right to find any zombies left. After checking that there are none, he carefully walked outside as he held the table in his hands. Rei didn't notice this first when he glanced outside, but now that he had leisure, he had finally noticed that there's something different outside the windows.

In the year 2130, artificial trees were spread around the world, but not one came close to the texture and smell of a natural tree. That's why when Rei saw the broken window on the wall, he couldn't help but gasp in surprise at the trees that surrounded the building.

He heard the groans of the trees and the rustling of the leaves; he felt the rhythm of the forest. An indescribable feeling surged up in his heart as he felt his tense body relax in comfort.

Rei had the urge to jump and hug one of the trees, but when he noticed that he's on the second floor, his face paled, and he finally woke up from his stupor. He took a deep breath and inhaled the fresh air that was released by the trees. Rei noticed that this air here in this world was entirely different than of his former world.

Rei did not know what was different, but he was aware that the air here is much better. After savoring the fresh air outside, Rei continued to proceed downstairs. His footsteps were silent, his breath was steady, and his mind was alert. There was not a single thing that could pass through Rei's gaze. There were no zombies on the stairs, but when he reached the first floor, he got the feeling that fighting was inevitable.

When Rei arrived on the first floor, he saw dozens of zombies walking around. But, Rei did not feel any pressure as he saw that there were all level one. Rei located the nearest zombie to him and decided that it would be his first target.

Rei gritted his teeth, and he steeled his heart, after seconds of preparations he quickly charged. It did not take six seconds before the zombie turned into a bloody paste. Rei then quickly moved back and hid behind his table to look for another zombie. After seconds of preparation, he charged off again.

In a matter of minutes, Rei wiped out the zombie horde, and although he eliminated the zombie horde, there was not a single smile on Rei's face. Every time he saw the results of his work, it would slightly make his stomach churn in disgust.

Rei sat down on the stairs, which was clean of blood and gore. He then drank what's left in his water bottle to invigorate his body. As Rei drank the water, a perplexed expression appeared on his face as he pondered about the previous battles.

"Am I strong, or the enemies are just weak?"

Rei started to ponder on this question since he first defeated the zombie that he encountered in the room. Rei wanted to fight someone stronger than him to test his combat prowess, but at the same time, he was afraid of fighting someone stronger than him.

"Ah, should I try punching the zombies?" An idea popped up in his head as he was just about to stand up. Rei's first plan was to find a civilization but knowing that he was in a middle of an unknown forest, it made Rei uncomfortable traveling the vast forest while being weak.

After moments of hesitation, Rei decided to use his body to eliminate the remaining zombies he could find. He looked at the hall of the first floor, which he fought the zombie horde, seeing that there was none left, he proceeded to the classrooms on the first floor.

It did not take long before Rei arrived in front of the room. Rei relaxed his body and took a deep breath; he opened the door slowly, and he immediately went inside. But what he saw inside made his solemn expression turn into a shocked one.

There were no zombies inside the room, nor any indiscernible meat that he found in his classroom but, what's strange here is that the room is squeaky clean! The tables are perfectly aligned, the chairs are not broken, and there were even some writings on the board.

Rei immediately rushed outside, and he headed straight for the other room, but it was the same as the previous one! He went to all the rooms on the first floor, and he found out that everything was perfectly normal.

He had a confused expression on his face as countless questions passed through his mind. But he did not pay them any heed, as he quickly went to the second floor and investigated the other rooms. He entered one room after another, and just as he expected, it was devoid of any destruction.

"This is eerily creepy," is what Rei thought after discovering that there were no mess on the other rooms. He tried to think of the reason on why his room would be the only one that was littered with meat and had broken furniture.

Rei also explored the third floor, and he found out that there was nothing there. Suspicions hung above his head as he tried to think of the reason on why there was no zombies or mess on the other floors. But, no matter how he thought about it, there was not a single thing in his mind that could justify the situation.

After two hours of searching any zombies, Rei discovered two anomalies. One is that there were no mess or signs of battle zombies on the other floors and rooms. Two is that almost all of the things except for the chairs and table are gone! The utensils are gone, even the refrigerator in the cooking room is gone!

"Dammit, hours of work and I found nothing!"

Rei cursed lightly as he sat on the chair on the third floor. His back was drenched with sweat, and large beads of it came down from his head. Anyone who saw him would think that he just took a bath! But, of course, anyone who would see him can also notice his bad mood and dark expression.

Rei carefully thought about his next actions after seeing that there were no zombies on the third floor and on the second floor

"Should I also check the rooftop?" Rei thought about this for a moment and decided to visit the rooftop.

Rei unsteady gaze and heavy breath resounded on the third floor as he climbed the stairs to the rooftop. Walking like this made him remember about a particular movie where the character ended up in heaven instead on the rooftop. It made him shiver unconsciously, but he just shook his head as he walked faster to reach the door leading to the rooftop.

With a tired face and ragged body, Rei finally arrived at the door leading to the rooftop, and without a moment's hesitation, he firmly grasped the doorknob and pushed the door outside.

Rei expected some zombies or at least the usual view of the rooftop that he always saw when he used to eat here. But the scene that he saw made his legs turn to jelly.
