A collective gasp, ragged and thin from hunger, ripped through the crowd at Yulan’s pronouncement. Elder Xu’s face, already etched with worry, contorted into a mask of pure terror. The cadre members, who moments before had been ready to condemn Yulan, stared as she pointed north. A low rumble began to roll from the ridge, vibrating the canvas awnings overhead before swelling into a hard patter. Cold droplets splattered the dry clay, then coalesced into a torrential downpour that lashed the brigade grounds. “The dam?” Brigade Chief Deng’s voice was a reedy squeak, barely audible over the sudden downpour and the rising murmurs of the crowd. “How… how could you? What about the children? The fields?” Yulan merely laughed, a sound utterly devoid of mirth, her eyes glinting with a mad triumph. “Let it all drown! Let it all be washed away! They were going to take everything from me anyway!” Lin Haiqiu’s mind, however, was already a hurricane of calculations. The dam was at least ten li distant, a winding, treacherous path across fields now turning to mud. On foot, they might be too late. She glanced at Song Zewen, his lips pressed flat, his gaze pinned to Yulan. He was already moving, pushing through the stunned crowd, heading towards his black sedan. “Wait!” Haiqiu’s voice cut through the chaos, sharp and commanding. Zewen paused, turning to her with tense impatience. “The sedan won’t make it on these paths. Not fast enough.” She met his gaze, a spark of resolve in her eyes. “I have something faster.” Without another word, she sprinted towards her cabin, the rain plastering her clothes to her body. Zewen, after a momentary hesitation, followed, his long strides easily keeping pace. The villagers watched, bewildered and terrified, as the two figures disappeared into the deluge. Chixue, a blur of spectral light, zipped ahead of Haiqiu, phasing through the cabin wall as she approached. Inside, the cabin was a flurry of motion. Haiqiu flung open a cleverly disguised panel in the back wall, revealing a passage that hummed with a faint, ethereal glow. The passage led not to a cellar, but to a shimmering, translucent membrane. She pushed through it, stepping into the clean, dry air of her personal dimension. “Chixue, the *Iron Ox*!” she commanded, her voice echoing in the vast, serene space. Before her, sitting under a tarp woven from luminous threads, was a marvel of ingenuity. It was a reinforced, motorized crawler, a prototype she had built in the time-dilated library from salvaged parts and futuristic blueprints. Its frame was a dark, sturdy metal, its wheels thick and deeply treaded, designed to conquer the most intractable terrain. The engine hummed with a potent, compact power, painted in utilitarian drab green to blend against brigade foliage. Zewen, who had followed her through the shimmering veil, stared, utterly dumbfounded. The world inside was breathtakingly vibrant, the air sweet with the scent of rich earth and burgeoning crops. Then his eyes locked onto the machine. “What… what is that?” he breathed, his usual composure utterly shattered. “It’s our only chance,” Haiqiu replied, already clambering onto the driver’s seat. “Get on.” He didn’t need to be told twice. He scrambled into the small passenger seat beside her, his hand instinctively gripping the side rail. Haiqiu engaged the ignition. The engine roared to life, a surprisingly quiet but powerful thrum that vibrated through the steel frame. She maneuvered the machine with practiced ease, steering it towards the portal. The boundary shimmered, then expanded, allowing the entire machine to pass through. The cabin wall resealed itself seamlessly behind them, the portal vanishing as if it had never been there. The *Iron Ox* burst from the cabin’s back, tearing through mud as its heavy tires found purchase. The rain was now a relentless deluge, the sky an angry, bruised purple. The path to the dam, usually a narrow dirt track, had transformed into a treacherous river of viscous mud and flowing water. The crawler bit deep into the slush, rumbling onward and cutting deep furrows through the mire. Zewen leaned close, shouting over the motor's growl and the drumming rain. “How far exactly?” “About ten li,” Haiqiu yelled back, her eyes narrowed, scanning the treacherous path ahead. “At this speed, twenty minutes. Less if the gullies hold.” They sped past bewildered villagers who had scattered from the assembly, their faces flickering from terror to awe as the strange, powerful machine thundered by. The world outside the cabin was a blur of rain-slicked fields and skeletal trees, the air thick with the smell of wet earth and desperation. Haiqiu drove with an unnerving precision, her hands steady on the wheel, her foot pressing the accelerator without hesitation. Every second counted. The dam came into view through the sheets of rain, a colossal, crude masonry structure holding back the swollen waters of the reservoir. A narrow access path, slick with algae and mud, wound up its side to the control house where the detonator would be located. But just as they reached the base of the structure, a figure emerged from the rain-lashed shadows of the control house. Shen Yulan. She was soaked to the bone, her hair plastered to her face, but in her hands, she held a militia rifle, its dark barrel glinting ominously. “You won’t stop it!” Yulan shrieked, her voice thin and ragged but filled with a renewed, desperate malice. Her eyes, wild and bloodshot, fixed on Zewen. She raised the rifle, her aim wobbling but deadly. “Get down!” Haiqiu roared, slamming on the brakes. The *Iron Ox* skidded, spraying slurry as it slowed. Zewen instinctively ducked, but Yulan had already squeezed the trigger. The shot whizzed past, tearing a hole in the air where Zewen’s head had been moments before. She was reloading, her movements clumsy but frantic. Haiqiu’s gaze swept over the toolbox beside her seat. Her fingers closed around a heavy, nine-pound steel wrench, cold and solid in her grip. Her mind, a whirlwind of vectors and trajectories, calculated the precise force, angle, and release point. With a grunt of effort, she flung the wrench, a blur of dark metal against the grey, rain-swept sky. The wrench spun end over end, cutting through the air with a whistling sound. It struck Yulan’s wrist with a sickening crack, just as she was bringing the rifle up for a second shot. The weapon flew from her shattered grasp, clattering against the concrete of the dam. Yulan screamed, a raw, primal sound of agony, clutching her mangled wrist. Her legs gave out, and she tumbled sideways, sliding down the slick, algae-covered incline into the freezing, muddy water at the dam’s base, her body vanishing beneath the surging brown torrent. Haiqiu didn’t spare her a second glance. “Go! The detonator!” Zewen was already scrambling out, slipping on the muddy path before catching his balance. They raced up the narrow access path, the rain still lashing them, towards the small control house. Inside, a crude, ticking device was wired to a thick cable that snaked out towards the dam’s interior. A plume of acrid smoke rose from the trigger housing, indicating the fuse was burning fast. Next to it, a massive, hand-cranked wheel, meant to open the main release valve, stood rusted and seized. It wouldn’t budge. “The valve is frozen!” Zewen yelled, putting his full weight into the wheel, but it remained stubbornly immobile. Haiqiu’s eyes darted from the ticking mechanism to the thick, explosive line, then to the roiling current below. The micro-weld tool from her space hummed in her pocket, a tiny, potent solution. But to sever the line, she would have to get close. Too close. She looked at Zewen, then back at the dark, swirling water, the roar of the spillway growing louder. There was only one way. She had to dive into the freezing, violent rapids to use her micro-weld tool to sever the explosive line, knowing the current might sweep her away forever.
