The obsidian gravity basin loomed beneath a sky warped by unseen weight, its blackened crater pulsing with a force that bent light into a haze of distorted shadows, each tremor a silent crush that pressed against the soul. Air hung heavy, its density squeezing the lungs, a relentless vow to collapse the heart into a single point. The ground was a slab of unyielding stone, cracked under invisible strain, each step a defiance against the basin's will to compress. Beyond a rift where the basin's core throbbed with a lightless pull, a chasm groaned—a crushing vortex that radiated a force so vast it could condense the cosmos into nothingness. The Gravity Sovereign, the ninety-ninth force, had stirred, its boundless weight of infinite power a thundering vow to compress Lin Feng's spirit into a singularity.
