A mysterious aura swirled around Baili An’s fingertips, unable to disperse, as the Demon Essence separated into countless free-floating filaments, moving in a highly regular trajectory following the Circulation path, gradually illuminating a star-like brilliance at the center of the iron box. The brilliance absorbed the purple Demon Essence filaments bit by bit, and suddenly, the speck of light burst forth radiantly. Baili An, as if holding the sun in his hands in the midst of night, saw the city’s towering structure Devoured by the supreme light. Following this was the resonant clang of countless weapons mingling within the brilliance, thunder and lightning continuously intertwining into weapons within the light. Not long after, when the light had completely retracted, Baili An held a dusky blue spear in his hands, the tail trailing a flame connected to the city’s structure. When the spear was formed, the flames followed the structure of the city and covered the entirety of the ground beneath Mo City’s Houtu. On the spearhead, thirty-six thin, membrane-like Light Wings spread open without any visible supports or connecting joints, defying the fundamental laws of weapon making, spontaneously forming thirty-six light umbrellas at the blade. Baili An had never seen a weapon that combined both a spear and an umbrella . Holding the weapon, much less massive than the giant Battle Axe, a mere lifting of his arm felt as though he was lifting the entire weight of Imperial City. His fingers unintentionally caressed the three characters engraved on the body of the spear. "Sky Mystery Umbrella..." Baili An couldn’t help but softly utter the name of the weapon. At that moment, the nearby clamor of Manxie’s warriors could be heard. Perhaps the ostentatious brilliance had attracted the attention of Manxie’s army, for the remote city tower was soon surrounded by soldiers, and cavalry in the sky pressed in like dark clouds looming over the city. Ning Feiyan, witnessing this, couldn’t help but expression turn grave; she summoned her Demon Blade, "Silly cat, if this gizmo of yours doesn’t work, both of us might meet our end here today." Although her tone was teasing, her gaze towards the army was exceptionally sharp. It was evident, even to the knowledgeable Ning Feiyan, that she couldn’t recognize the kind of weapon Baili An was holding. Suddenly, the sky darkened as the winged Manxie forces riding Griffins swooped down, flying diagonally from both sides, not hastily initiating an attack. Instead, they formed an enclosing formation, cutting off any escape route for the two on the city wall, and then set up their crossbows in the air. Bone Arrows, tainted with vicious Ghost Fire, shot towards the two on the wall like a storm. Ning Feiyan frowned, "The Acquired Spirit Root created by Shen Jibai really is something, it’s even made these brainless brutes knowledgeable in using Ghost Fire poisoned arrows." The phosphorescent Ghost Fire bathed the city wall as if it were the fires of Purgatory, the slender, narrow Demon Blade drawn through the air creating a trail of sparks. Her Demon Blade was born from the Demon Emperor’s Curse Fire and half of Beiyuan’s regional spirit veins—an artifact of her lifebound spirit, where each weak spark looked like fireflies unable to escape a torrential downpour of silvery rain. Yet those flickering sparks held an awe-inducing imperial authority, instantly carving out a sweeping scope, one strike intercepting the charging thousands. Dozens of Griffin heads fell, spewing blood as they dropped. Ning Feiyan’s smile faded as she stood bathed in the battlefield’s bloody breeze, stepping over Griffin heads and flipping five incoming Manxie warriors with a single slash, smoothly catching one of their fallen crossbows. Her slender fingers nimbly drew the bow and notched ten Bone Arrows, the shafts swirling with Purple Butterflies. With a flick of her finger, the tense bowstring vibrated fiercely, and the ten Bone Arrows vanished from the bow. The sky responded with ten colossal blood-red voids. Within the dense army, she single-handedly created ten gory spaces. Before Ning Feiyan could summon her Demon Butterflies, the Griffin skull she was standing on suddenly trembled, and its eyes, covered in a deathly glaze, suddenly burst open; a bloody hand broke through and grasped Ning Feiyan’s ankle! Ning Feiyan had never imagined that someone could be hiding inside a Griffin’s head, feeling a sudden immense force beneath her dragging her into a muddy pool of blood. The blood pool rapidly boiled like oil, relentlessly churning, and a winged demon—his body bathed in scalding fresh blood—crawled out of the skull. Ning Feiyan caught glimpses of swirling, writhing Blood Worms in the boiling blood pool and immediately understood. Each Griffin on this battlefield might have long been turned into corpses, and it was the Gu Insects within the bodies that were actually controlling them. Ning Feiyan, also a master of Gu Path—though the Enchanting Demon clan did not originate from this path—had learned her Gu Insect nurturing techniques from a tribe in the Wilderness domain. Without a second thought, she swung her blade downward, powering through her stance, turning the Griffin’s head into a mist of blood. The Winged Demon hidden within the skull was fully exposed, his skin a fiery red, with a pair of eyes growing at his waist, seemingly constantly shedding bloody tears—but upon closer inspection, the crimson ’blood tears’ turned out to be endlessly streaming red corpse worms. His back heaved, regenerating two more arms, spreading them horizontally. One hand blocked Ning Feiyan’s descending Demon Blade, while his other sturdy hand grasped her neck from behind. The Blade cut into flesh but couldn’t sever bone. This Winged Demon had actually caught her blade barehanded, and Ning Feiyan realized in alarm that she might have encountered a General among the Winged Demons. Sure enough, the voice of a man behind her slowly rose, "I’ve long heard that the River Lord of Si He was gravely poisoned by the Nine-Headed Snake Clan, and today’s battle proves it indeed." If it had been any other time—even if he was a king among Winged Demons, even if he had the means for a sneak attack—facing a true sovereign like the River Lord of the Demon World, how would he dare to engage her in close combat? Even at this moment, he dared not engage in idle talk with Ning Feiyan, fearing an unexpected turn of events. He spread his wings and descended, seemingly preparing to slowly devour Ning Feiyan by wrapping her entirely within his body. Ning Feiyan sensed his intentions, her gaze chilling. Glancing back in an instant, the pair of wings wrapping towards her suddenly scattered like dandelion seeds blown awry by the wind. A look of painful confusion slowly surfaced in the dilating vertical pupils of the Winged Demon—he seemed utterly unable to comprehend what had just occurred. The hand clutching Ning Feiyan’s neck turned rigidly cold and powerless. Ning Feiyan slowly turned and stared straight at him, seeing a thin red line traced from his shoulder down to his waist. His eyes gradually filled with blood, and the writhing corpse worms within his eye sockets seemed instantly drained of life and fell silent. His body was cleanly split; the cut as smooth as a mirror, his upper body sliding off at an angle. "Ah..." The Winged Demon let out a deathly hoarse cry, his six arms desperately flailing in mid-air, as if trying to grasp something. But the extended six arms quickly disintegrated into small chunks of blood which then dispersed into even smaller blood pearls, turning into a mist of blood that finally vanished completely. The head of the Winged Demon vanished just like that. Through the crimson mist, Ning Feiyan saw Baili An standing with his spear on the city wall, the umbrella of his spear slowly rotating, one of its leaves twinkling with a strand of light; that light was slowly pulling in the life force of the Winged Demon. A new trail of blood appeared on the membrane-like umbrella surface. The death of the Winged Demon general ignited the rage of the remaining Griffin Army, causing an instant loss of control—they even ignored the Manxie cavalry’s commands and roared furiously as they surged in attack. Baili An’s gaze briefly swept across the umbrella surface, serenely locating the corresponding rune on the umbrella and spear body. His finger lightly touched the rune, channeling Spiritual Power into it; the thirty-six umbrella leaves slowly rotated, a purple intent from the spear tip pinpointing the corresponding line of runes on one of the leaves. The leaf was then immobilized, projecting an indescribable vast, profound, indifferent, and cruel aura that transmitted into everyone’s heart, so chilling that it felt as though they all had plummeted into an endless void. The violet wisps of light unfurled like the tendrils of death, penetrating the bodies of over a thousand cavalry in the sky. The threads were extremely fine and long, striking as swiftly as lightning with an almost gentle, picturesque beauty, devoid of bloodshed, except for a slight tinge of red drawn out at the moment of retraction—even in killing, the Sky Mystery Umbrella embodied an elegant, meticulous aesthetic of murder. Bodies fell like rain.
