The Rune Shopkeeper

[Shopkeeper, fantasy, runes, leveling up, farming, apocalypse, System, wilderness survival]

The System is just for fun. But if you really want to have fun, nothing beats runes:

He runs a shop in a world of swords and magic,

He runs one in the world of cultivation, too,

And he even mines and runs a shop on Earth after the apocalypse.

He opens up shop in the mysterious Rune Wilderness, but when that isn't possible, he takes on the wilderness in a survival adventure.

Oh, right,

He's a lazy fish.
