Legend has it that there is a mountain stretching a thousand li, also known as Thousand-Li Mountain, riddled with countless caves.
They say mice are good at digging holes. So, according to legend, the caves in Thousand-Li Mountain were dug by a group of dragons who descended from the mountain and gathered up a heap of mice. Over time, the diligent dragons overseeing the work filled the mountain with cave after cave.
All the caves across the mountain were made for the belly of the Great Black Dragon, to prepare for the eggs inside it. The caves were ready, and the eggs in the dragon's belly were ready to hatch...
After countless tribulations in the primordial age, as all things rose and fell, that distant history became legend. Someone closed the book, and a seed took root in their heart. After a few seconds of the long river of history, they snapped off a branch to use as a sword and set out on their journey.
