Join Dale Mitchell, your run-of-the-mill truck driver. Until one day, he accidentally runs someone over. Now, through a series of strange and unforeseeable circumstances, he has become anything but normal. A story of magic, of a history that never was, and of a man trying to go through his day-to-day life while managing the affairs of an entire world. Join Dale Mitchell on his journey.

Alexandra Rousseau, an engineer from the European Federation Star Navy with a past darker than the void between the stars, is unexpectedly launched into hyperspace when an FTL jump goes horribly wrong. She wakes in a world of magic and monsters, encountering a mysterious Order with plans millennia in the making. When the Order makes a catastrophic mistake, transforming Alexandra into a dungeon core, they inadvertently give her the power to bring back technology long since thought lost in this world.

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

Millions of dungeons inhabit the planet, utilizing the Human people as a source of much-needed Mana to facilitate their own growth; in turn, the humans delve into the dungeons to acquire their own power in the form of Essence, which allows them to develop and enhance themselves in a multitude of different ways. It is a symbiotic relationship that has lasted thousands of years and has brought about a measure of peace.

Jin Rou wanted to be a cultivator. A man powerful enough to defy the heavens. A master of martial arts. A lord of spiritual power. Unfortunately for him, he died, and now I’m stuck in his body. Arrogant Masters? Heavenly Tribulations? All that violence and bloodshed? Yeah, no thanks. I’m getting out of here. Farm life sounds pretty great. Tilling a field by hand is fun when you’ve got the strength of ten men—though maybe I shouldn’t have fed those Spirit Herbs to my pet rooster.
