The crag tore open with a sound like a giant’s sigh, not a sudden collapse, but a drawn-out rending of stone. Yunya felt the stone drop away first, the sudden plunge cutting off her sweet giggle. Her feet scrabbled at the crumbling edge, a futile dance on the precipice. Time stretched, thick and sluggish, as the darkness below swallowed the last vestiges of the sulfur haze. Her world tilted, and then she was falling, a silent, helpless plummet into the unknown. But a rough, calloused hand clamped around her waist, yanking her sideways with impossible force. He Zhenting had moved. He didn’t shout, didn’t hesitate. His body, a hard, unyielding shield, twisted beneath her, absorbing the shock of their descent. He pulled her tight against him, a desperate, protective embrace. The wind roared past their ears, a hungry beast devouring sound. Yunya’s head collided with his chest, and she heard the frantic beat of his heart against her ear, a wild drum in the rapidly deepening gloom. They landed with a bone-jarring thud. Not on jagged rocks, but on something softer, yielding. A mound of fine, loose earth. Zhenting grunted, a sharp intake of breath. He still held her, a vise of muscle and resolve. Dust choked the air, stinging her eyes and coating her tongue. When the swirling motes settled, a vast, oppressive space revealed itself, stretching into an inky blackness that seemed to mock the faint light filtering from the crack above. “Are you hurt?” His voice was a low growl, rough with concern, his grip tightening on her arm. He ran his other hand over her head, checking for bumps, his movements surprisingly gentle despite the urgency. “A little dusty,” Yunya managed, her voice a reedy thing, the shock finally catching up to her. Her eyes, however, were already adjusting, wide and curious. The subterranean chamber was vast, carved out by hidden water or ancient shifts. The walls shimmered with metallic veins, and a dull, mossy green light pulsed from a mineral deposit overhead. But what caught her attention were the objects scattered across the bedrock. Wooden crates, stacked haphazardly, were everywhere. Many had burst open, spilling their contents: gleaming bronzeware, intricate porcelain vases, delicate silk scrolls, and, most dazzling of all, raw veins of jade, some as thick as a man’s forearm, snaking through the flagstones and catching what little light remained. This wasn't just a tunnel; it was a forgotten vault, a king’s ransom in stolen national treasures. The sheer scale of it was staggering. Then, a cough, wet and ragged, echoed from the shadows. Accountant Liu Guang stumbled into the faint light, his face a mask of terror and rage, smeared with grime. He clutched a small, black pistol, its barrel wavering in his trembling hand. Behind him, two more trench-hands, their faces bruised and their clothes torn from the blast and debris, crawled from behind a stack of crates, groaning softly. “You… you ruined everything!” Liu Guang shrieked, his voice cracking. The pistol jerked up, aiming squarely at Yunya. “I’ll kill you! All of you!” Yunya didn't flinch. She simply tilted her head, a sweet, unreadable smile gracing her lips. “Oh, Accountant Liu. It seems you’ve been caught in your own trap, haven’t you?” “Silence, you parasite!” He snarled, his eyes bulging. His finger tightened on the trigger. Before he could squeeze, a dark, furry projectile descended from the inky blackness above, a blur of indignant rage and considerable mass. Daodao, roaring like a miniature lion, landed with a squishy thud directly on Liu Guang’s face. The accountant let out a choked yelp, the pistol flying from his hand and skittering across the flagstones. Daodao, all teeth and claws, began to maul his target with furious enthusiasm, a furry, growling tornado of badger fury. Zhenting didn't waste a second. He shoved Yunya behind a particularly large crate of ceremonial pottery, a low warning rumble in his throat. He moved with the brutal efficiency of a trained predator, silent and swift. The first smuggler, still dazed, tried to tackle him. Zhenting sidestepped, pivoted, and delivered a devastating elbow to the man’s jaw. A dull crack followed, and the laborer crumpled to the dirt, motionless. The second man, seeing his partner fall, lunged with a rusted pickaxe. Zhenting met him with a sharp kick to the knee, eliciting a howl of pain. As the man buckled, Zhenting twisted the pickaxe from his grasp, sending it spinning into the dark, then drove a fist straight into his temple. That man, too, joined his cohort on the floor. Daodao, meanwhile, had finished his work on Liu Guang, who lay groaning, his face a bloody mess of scratches and bite marks. The badger waddled over to Yunya, nudging her hand with his snout, a proud, satisfied grunt rumbling in his chest. Yunya, stroking his thick fur, offered him a genuinely delighted smile. “Good boy, Daodao. Very good.” Zhenting scanned the chamber, his posture rigid. The immediate brawl had ended, but the bedrock beneath their boots still shuddered faintly. A steady drizzle of grit sifted down from the limestone above. A faint, almost imperceptible groan resonated through the stone. “The dynamite… it’s destabilized the whole structure,” he murmured, his gaze flicking upwards. A hairline fracture split across the limestone above them, lengthening fast. It widened, slowly at first, then with alarming speed. “We need to get out,” Yunya said, her voice devoid of panic, though her eyes were fixed on the widening fissure. “Now.” A massive slab of shale tore free overhead with a harsh grind, sending a cascade of debris crashing down. Zhenting grabbed Yunya’s arm, pulling her towards a narrow, jagged fissure in the far wall – a potential escape route, a chimney of sorts that seemed to lead upwards. He boosted her, pushing her through the tight opening. Just as Yunya scrambled through, her hand finding a rough ledge, a violent tremor shook the vault. A massive chunk of rock above the stacked crates gave way, dislodging a small, intricately carved wooden box. The box tumbled into the open, its brass latch popping apart. Sitting on the packed dirt, carved from mutton-fat nephrite, rested an Imperial seal, its cut edges catching the greenish mineral glow. Zhenting’s eyes locked onto it, his mission, his entire undercover life, flashing before him. The prize. The very reason he was here. He took a single, instinctive step towards it. Another tremor tore through the chamber, and the ledge Yunya clung to began to fracture, spitting gravel down into the dark. She cried out, her foot slipping. The crack above her widened, threatening to swallow her whole. Zhenting had to choose. He could lunge for the priceless Imperial Jade Seal, or he could use both hands to pull Yunya up the collapsing ledge to safety.
