In the magical sea at the edge of the world, Mu Lan drifts in the waves of disorder as a "remnant of the old world". The treasures here are not just gold and silver, but "source cores" that can rewrite reality. They reshape themselves in drastic changes, inducing crazy fission in the sea and people's hearts. When power, faith and memory were eroded by the source core, Mu Lan embarked on a treasure hunt, only to find that she was the trigger point of the legendary change. He tried to use the source core to reverse the collapse of the sea area, but with every decision he made, he personally tore apart the inherent order. Treasures and destruction coexist, the rage of the ocean intersects with the cracks in human nature, and Mu Lan struggles between loss and awakening. The novel uses drastic changes as its background, breaks the traditional treasure hunt narrative, and explores the reshaping of power, the rebirth of civilization, and the boundaries of self-awareness - should we choose to protect the remaining old world, or reforge a new life with flames?
