The emerald serpent hollow hissed beneath a sky veiled in shadow, its tangled vines dripping with venomous dew that gleamed with malice, each drop a whisper of confinement that coiled around the heart. Mists slithered, their chill biting the skin, a sinuous dance of darkness that promised to bind the soul in endless loops. The ground was soft, a mire of roots that clutched at the feet, each step a struggle against the hollow's grip. Beyond a rift where the hollow's core pulsed with verdant gloom, a chasm writhed—a shadowed vortex that radiated a force so vast it could strangle eternity itself. The Serpent Shade, the eighty-ninth force, had stirred, its boundless current of infinite power a slithering vow to bind Lin Feng's spirit in its coils.
