Argon got Isekaid to another world, and also got a system that can help him build a dungeon in a cultivation world, where people can get amazing treasures inside.And for our mc to get enough resources for upgrading the dungeon he also needs to kill the people that will enter his dungeon to get soul coins that will help him upgrade the dungeon.In a world where cultivation is the key to power and strength. Argon has the power to create dungeons - underground labyrinths filled with powerful monsters and valuable treasures.Using his unique abilities, Argon creates a dungeon in the heart of an unknown forest, hoping to attract powerful cultivators and increase his own strength. But as his dungeon grows in size and power, the top powerhouses in the world realized the danger of the dungeon, since the dungeon would pour out unknown monsters that will wreak havoc in the world.To survive in this new world, Argon must use all his cunning and strength to navigate the treacherous world of cultivation and defend his dungeon from those who seek to destroy it.

The world was never the same after that day.Humanity learned that they weren't alone in the universe, but that wasn't something they had the time to worry about.Their realization was accompanied by catastrophe.Creatures beyond their wildest imaginations poured down from the sky and appeared from the earth. They slaughtered humans as if it was their singular purpose, driving them to the brink of extinction.The people of the world did everything in their power, developing unique traits and technologies to create a united front their enemies couldn't penetrate.They secured victories and repopulated, feeling as if they stood a chance against the foreign invaders.They fought and they fought, doing everything they possibly could to ensure their survival.Until the Great Calamities appeared.In front of them, humanity was nothing regardless of its efforts.One by one, the worlds were turned into piles of rubble in between the cracks of their teeth. Civilization was torn apart, and the evolved humans living within could do nothing to stop its collapse.Humanity itself was left extinct, and in the end, only a single man was left alive amidst the chaos.Why?For what reason were they punished so?Nobody knew why the attacks began in the first place.He looked into the distance at the memories of the past and firmed his resolve.“It can only be me.”He knew of a miracle that could return him to the place of those memories.He knew of a way to make the wheels of time spin in reverse.And using it, he alone would save humanity from its doomed fate.That was his sacred duty as its final survivor.
