The mountain gorge groaned under its own weight, its cliffs splintered into jagged slabs that loomed like broken giants, casting shadows heavy enough to bruise the earth. Dust swirled, a gritty veil that clung to the throat and dimmed the sun to a sickly bronze. The air pressed down, thick with a force that bent the spine and slowed the heart—a gravity that wasn't mere stone but something deeper, final. Beyond a pile of shattered rock, where the gorge seemed to choke on itself, a rift pulsed—an obsidian scar that radiated a density so vast it could crush the sky. The Graviton Mass, the fiftieth force, had stirred, its boundless pressure of infinite power a silent vow to collapse Lin Feng's spirit to dust.
