In the mysterious world where spiritual veins are exhausted and shadow pollution is rampant, Lin Jin, a "waste" young man, carries the mystery of his adoptive father's life and life experience, and embarks on a dangerous journey with Xingying, a mysterious girl who possesses a pure spiritual source. Using their martial arts to burn the sky and their spiritual skills to weave light, they struggled to be hunted down by a cult that believed in shadow erosion and the "Linguang Society" that monopolized spiritual veins. They gradually uncovered the cruel truth about the failure of the "Great Source Vein Project" thousands of years ago - shadow erosion was not a natural disaster, but a man-made disaster! The silent Jinghuo Gangyuan in Lin Jin's body and the pure spiritual source of Xingying became the key to breaking the situation. In order to end the long night, they must go deep into the source of the shadow, and between the choices of devouring and purifying, sacrifice and redemption, they must ignite a prairie fire that burns away the darkness.
