Spiritual energy fills the world. Since ancient times, humanity has revered the cultivation of spiritual essence: opening spirit channels, condensing spirit cores, and forging spirit flames. This is the path of spiritual cultivation.
There are nine realms of spiritual cultivation: Spirit Awakening, Spirit Gathering, Spirit Condensation, Spirit Core, Spirit Soul, Spirit King, Spirit Emperor, Spirit Saint, and Spirit Sovereign. The gap in power between each realm is like a chasm, and those who can defeat opponents above their level are one in ten thousand.
The world's spirit flames are divided into three grades: Heaven, Earth, and Human. Human flames are the lowest, refined from mortal flames; Earth flames are in the middle, forged from the Earth's magma; Heaven flames are supreme, said to be the ashes left behind when ancient gods fell. Obtaining even a single Heaven flame can let a cultivator defy fate and undergo a complete transformation.
Spirit flames can be fused, and fusion makes them fiercer. But the stronger the flame, the more violent its backlash. The slightest mistake means total annihilation. Thus, those who cultivate spirit flames face death nine times out of ten.
The Tianxuan Continent is vast, with sects standing everywhere. The Spirit Sect of the Eastern Region, the Demon Sect of the Western Region, the Medicine Sect of the Southern Region, and the Sword Sect of the Northern Region stand as the four great sects, dividing the world between them. At the continent's center stands the Xuantian Divine Palace, guarded by a Spirit Sovereign. It rules over countless nations and commands the path of spiritual cultivation.
The story begins with a small, declining family in the Eastern Region...
