The Flame Blade Quells the Turbid World

The Boundary River divides the world in two: the clear realm above and the turbid realm below. Each is ruled by a faction, the Upper Qing Kingdom and the Lower Zhuo Prefecture. Two cities lie along the Boundary River, one upstream and one downstream: Qingzhuo City and Chaos City. Qingzhuo City governs the mortal world, while Chaos City is mysterious and inscrutable.

Mortals can cultivate qi while alive and shed their mortal nature to become beings of the clear realm, or absorb yin after death and cultivate in the turbid realm. Neither the clear nor the turbid path is inherently righteous or evil, and under normal circumstances, the two cannot be cultivated together.

The factions of the Upper Qing and Lower Zhuo realms scheme against each other, constantly fighting over resources and opportunities. Now the followers of the Hunyuan Sect have appeared. What kind of turmoil will they bring?
