The abyss hollow yawned beneath a sky devoured by shadow, its jagged walls cloaked in a darkness so profound it drank light, each crevice a pulse of absence that gnawed at the mind. Wisps of black mist coiled through the air, clinging to the skin with a cold that sapped warmth, their tendrils a silent vow of oblivion. The ground was slick, a mire of unseen sludge that sucked at the feet, whispering of surrender with every step. Beyond a rift where the hollow's core pulsed with obsidian void, a chasm seethed—a liquid darkness that radiated a force so vast it could swallow existence itself. The Shadow Abyss, the seventy-eighth force, had stirred, its boundless void of infinite power a silent vow to drown Lin Feng's spirit in darkness.
