I Can Make Everything Level UP

Many generations ago, before the capitals of the states were built, the world was in total chaos. Monsters could be found everywhere, and they were a lot bigger and powerful than the current ones that could be found in dungeons. Those beasts could easily level any settlements and camps that humans could build in a matter of seconds. Around the time, most humans lived traveling around, and they only created bases when weather conditions forced them to stop. When the snow started to pile up, or when storms approached, for whatever reason, the weather was a lot worse than it is today.

"The weather, huh…" Billy thought. "I wonder if it was due to the presence of those powerful beats that walked around like they owned the world."

Humans could multiply faster than the monsters, but their numbers never increased in those times. The tribes that were lucky managed to lose people and quickly give birth to the same number of the fallen. However, it was clear that something had to be done. Eventually, those tribes began to fight against the monsters. Little by little, humans began to gain power and use tactics against the beasts. However, when humans started to win the fight, something happened… A new spot where monsters could appear endlessly showed up, they were the dungeons, and thanks to it, the human race began to lose the fight again.

"This timing… Is just too weird," Billy thought. "It is almost like someone intervened to help the monsters."

Once again, the humans were put in a bad spot against the monsters. For many years, nothing improved for them. However, several leaders began to emerge among the tribes, and they began to fight back against the beasts. They were inhumanly powerful, and some of them even had powers that people couldn't explain or understand. Those people turned into leaders and made their people prosper like never before. The first cities were built by them, and then they started to refer to themselves as kings. Eventually, the kings started to increase the size of their territories, and when they finally met each other. At first, they tried to compromise, but eventually, conflicts began among them. For several decades, they put aside the problem that was the monsters and thus fought amongst themselves. Eventually, they began to die, and one emerged victorious among the others. Things prospered for a while, but then that king suddenly disappeared.

"Those dumbasses… They certainly were reincarnated individuals…" Billy thought. "It seems that this tale is more or less true since the same thing happened to Galatea. However, she didn't win any war…"

Thanks to those kings, the human race managed to learn a lot, and even without them, they managed to prosper and slowly reached their way to the top of the food chain thanks to their numbers and brains. It wasn't much different from things on Earth. The only difference was that the existence of mana made them a lot more powerful. Still, they never managed to become even closer as strong as those kings that made history in that world. That was because they never had many chances to improve themselves. Wars of conquest happened here and there, but they were far too far in between due to the logistics. The armies couldn't travel for weeks without hoping to be ambushed, and their food never lasted that long.

Eventually, more strange individuals emerged, and then they revolutionized the world with their inventions and powers. The human race began to prosper again, to the point that they exterminated most of the beasts outside dungeons. Still, once they got rid of that problem, they began to target each other once again. Those individuals never managed to get along, and they were always fighting…

"I guess any human race really needs an enemy in common to fight together. Otherwise, they begin to attack each other to stand at the top, truly useless…" Billy thought. "Perhaps this kind of species truly deserved to face extinction…"

Billy shook his head to get rid of those dark thoughts… It wasn't like all humans were like that. Only a small fraction that tends to be really noisy when they want. That being said, he confirmed several things that he knew… Reincarnated people have been appearing in that world for a while, and when they do, they always bring change and make things speed up in many fields. Nevertheless, from Billy's point of view, they brought more problems than anything since they involved and caused the death of countless people. Even without them, things like politics developed on their own, the management of dungeon towns, and the question of peace treaties.

Billy was impressed that somehow so much history managed to be passed down. He was also improved that somehow the author of the book managed to conclude that individuals like him appeared once every five hundred years. It was hard to be sure, but it seemed that he was part of the sixth or seventh group that was reborn in that world.

Around the time the fourth group appeared, some massive birds also began to attack all human cities and destroy them with ease. Apparently, they had the power of fire, ice, and thunder… It was quite the odd number of monsters considering that their powers were similar to the titans. Billy wondered if they could be related, but apparently, they were defeated when all the armies of the world and all of the leaders put aside their differences…

After they were killed, those massive birds were never found again, nor were they mentioned in the history of that world. The author of the book did some research, but he never managed to find any traces of their origins.

Finally, the book began to mention the history of that state. It started around five hundred years ago, and the one who named the state was the first ruler. A man who had the weird power to use all forms of weapons with supernatural mastery, even when he touched them for the first time…
