Generate a strictly 25-second, 16:9, cinematic-grade photorealistic original indoor action sequence. Change the protagonist to a young, attractive East Asian woman, and change the setting to a nighttime university classroom; the original fight choreography, sequence of actions, timing beats, attack directions, hit-reactions, and camera rhythm must all remain unchanged. All characters are fictional adults; none imitate any actor, film character, or existing film/TV footage. [Environment Lock] A late-night, aging university lecture-hall classroom, long and narrow, with a low ceiling and mottled, yellowed walls, the lower half painted in faded dark green. Cold white old-style fluorescent lights flicker intermittently; chalk dust and dust motes float in the air. The center of the classroom holds multiple rows of dark brown wooden desks with matching wooden chairs; to the rear right is a large green-topped teaching/lab bench; in the center, several student desks are pushed together to form a discussion table; on the left side of the frame is a worn brown reading sofa and a small coffee table holding glass beverage bottles; along the right wall stands a tall wooden bookcase against a cracked wall; at the rear center is a narrow classroom exit. The blackboard shows only blurred chalk marks, with no legible text; a corner holds an old TV set flickering with static. All desks, chairs, books, chalk, broken glass, and fallen characters must remain continuous — they must not automatically reset after a cut. [Fixed Characters] Protagonist A: an East Asian woman of about 18 @[Image 1](image_1) A keeps the same face, same hairstyle, same body, and same outfit throughout. Her movements are clean, composed, and powerful, with no exaggerated feminized posing. Midway through, her left sleeve is soaked with alcohol and her ponytail becomes slightly loose; by the end her breathing is a bit heavier, but she has no visible wounds. Attacker B: an adult male, bald, muscular, wearing an old white tank top, blue-gray jeans, black boots, a gold chain, and a pendant. He is the first to provoke A, then crashes into the large green teaching/lab bench at the rear right, and remains down beside the broken desk for the rest of the scene. Attacker C: an adult, stocky, short-haired man, wearing an open black short-sleeve work shirt, black tank top, and gray pants, swinging a wooden chair with both hands. He is kicked in the chest/abdomen and slams into the right-side wall, then slides down along the wall and does not get up again. Attacker D: an adult male, thickly built, wearing an old charcoal-gray jacket, black top, and dark trousers, charging in at high speed from the direction of the classroom's rear door. Using D's own momentum, A throws him into the central assembled desk-cluster, after which he remains among the overturned desks and scattered books. Attacker E: an adult male with disheveled hair, wearing a thin black jacket, black tank top, and gray jeans, holding a clear glass beverage bottle in his right hand. His bottle attack is intercepted, and he is then knocked back onto the reading sofa on the left; the bottle drops in front of the sofa and must not reappear in his hand. Attacker F: the last adult male to appear, short hair, wearing an olive-brown work jacket, black top, and dark gray trousers, throwing a continuous series of close-range punches, and finally knocked down at the front of the frame with his center of gravity driven low. Fixed background characters: six adult university students total in the background, three men and three women, all over 20 years old. When the fight begins, two retreat toward the classroom exit, two crouch behind the back-row desks, and two press against the wall covering their heads. They only react with startled retreats, evasive dodging, and peeking glances — they never join the fight, and never suddenly vanish, duplicate, or change clothes. [Spatial and Camera Rules] At the opening, A is positioned on the left side of the frame facing right; B is positioned on the right side of the frame facing left. The primary action axis remains consistently left-right. The camera may only change its viewing direction after re-establishing the classroom's spatial layout via a 24mm wide shot or a high-angle overhead shot. Use 24mm, 35mm, and 50mm lenses, close-in handheld camerawork, rapid lateral pans, and short whip-pans. A slight 2-to-3-frame speed variation is allowed at the moment of impact, but slow motion, freeze-frames, and repeated replays are prohibited. Every hit to the body must first clearly show the point of contact, then show the head snapping, the torso folding, footing becoming unbalanced, and secondary collisions with desks, chairs, or walls. Although A is more slender than her attackers, she completes each move through precise timing, speed, hip rotation, and the opponent's own momentum — do not portray her as having superhuman abilities. [25-Second Continuous Shot Breakdown] 0.00–2.20s: 50mm over-the-shoulder medium-close shot. A stands with her back to the camera in the left foreground, her low ponytail hanging out from beneath a black baseball cap. B stands in front of the green teaching/lab bench on the right, approaching with a sneer, and claps his right hand onto A's left shoulder. A keeps her head down and stays still, confirming B's position only with the corner of her eye. The six adult students in the background stop talking and look toward the two of them warily. 2.20–3.40s: Close handheld close-up. B's hand is still resting on A's shoulder when A suddenly spins clockwise, her low ponytail whipping around with the turn; her right forearm strikes B's jaw and cheek precisely along a horizontal trajectory. The point of contact is clear; B's head snaps violently backward and to the right, his chain flies up, and his feet lose their footing. A immediately withdraws her arm after the hit, without pausing or posing. 3.40–4.75s: 24mm high-angle wide shot, tracking downward. B falls backward into the large green teaching/lab bench at the rear right, his back crushing the tabletop as the table legs splay outward; textbooks, workbooks, a chalk box, papers, and a glass fall from the tabletop onto the concrete floor. Nearby students flip over their chairs as they retreat, arms shielding their faces. B lies on his back among the broken desk debris, chest heaving but no longer fighting. 4.75–6.90s: Rapid whip-pan to the right side of the frame. C grabs a dark brown wooden chair and swings it horizontally at A's head from the rear right. A leans back, letting the chair back sweep past just in front of her cap brim; her low ponytail swings backward from the momentum. She immediately closes the distance, and before C can retract the chair, lands a precise left-foot side kick to his chest and abdomen. C flies toward the right wall, chair and all, his back slamming into the cracked wall; chalk dust, plaster fragments, and old wall coating fall downward. The wooden chair falls from his grip; C slides down the wall into a seated position and does not get up again. 6.90–8.25s: 35mm side medium shot. A withdraws her left leg and re-establishes her footing in the center of the classroom, her gaze sweeping from the right wall toward the rear door. The fallen B is still beside the broken desk at the rear right; C remains beneath the right wall. Two background students seize the opening to rush toward the rear door; the other four continue to crouch. The camera moves slightly counterclockwise around A, using a wide angle to re-establish the direction of the next attacker. 8.25–10.45s: D charges at A from the rear center at high speed, first throwing a right hook. A ducks and slides to the left side of the frame, the fist grazing past the top of her cap; she closes in under D's armpit, driving her shoulder into his chest, controlling his waist and hips with both arms, and using D's forward momentum to rotate her hips. The camera moves laterally alongside the two of them. D's feet leave the ground as his body flips sideways over A's back, crashing into the discussion table formed from several student desks in the center. The desks collapse inward, wooden chairs topple over, and textbooks, notebooks, and chalk slide toward the camera. D remains among the wrecked desks and does not get up again. 10.45–13.30s: E raises a clear glass beverage bottle overhead from beside the reading sofa at the rear left and smashes it down at A. A turns and raises her left forearm, intercepting E's wrist before the bottle comes down; the sudden stop causes the liquid to burst out of the bottle's mouth, splashing A's cap brim, cheek, and left sleeve. A cups E's elbow with her right palm, twisting to pull the bottle-holding arm away from her own head, then delivers a short forearm strike to E's face, followed by a palm-heel strike to his chest. E staggers back three steps and collapses onto the brown reading sofa on the left. The bottle falls from his hand, rolls to a stop in front of the sofa, and must not return to his hand in any subsequent shot. 13.30–14.20s: Brief medium-shot bridging moment. A shakes the alcohol off her left sleeve and flicks her loosened ponytail back over her shoulder, her body still holding a side-on defensive stance. E is slumped in the sofa, covering his face. The camera pulls back from A's left shoulder, revealing F approaching from the classroom's rear door. The remaining four background students are hiding behind the back-row desks and in the corner, without changing identity or position. 14.20–17.00s: 50mm close-in orbiting shot. F throws a series of blows from the right side of the frame — a right straight punch, a left hook, and a right elbow. A does not retreat: she slightly tilts her head to dodge the straight punch, slaps away the hook with her left palm, and blocks the elbow with her right forearm; she then lands a short, sharp palm strike to F's sternum, followed by a shoulder check into his upper chest. F staggers back half a step but does not fall, a slight trace of blood appearing at the corner of his mouth. The camera stays tight on the two of them's arms and upper bodies, clearly showing the blocks, contact, and impact, without letting hair, the cap, or motion blur obscure either character's identity. 17.00–20.00s: F angrily throws another pair of wide left-right hooks. A first dodges to the right to avoid the first punch, then lowers her center of gravity to duck under the second, simultaneously grabbing F's right wrist and pulling his arm across in front of her own shoulder. A delivers a short left-elbow strike to F's ribs, followed by a right palm strike to his jaw. F's upper body tilts backward; his feet slip on scattered books and the chalk box, knocking over a wooden chair, but he barely avoids falling by grabbing A's shoulder. A's cap, low ponytail, black outfit, and damp left sleeve remain unchanged throughout. 20.00–22.30s: F launches one final frontal charge. A steps diagonally to the left to avoid the charge line, pressing her right hand against the back of F's neck while her left hand controls his arm, pulling F's upper body forward and downward. A then raises her right elbow and delivers a short downward strike to the junction of F's shoulder and back, blocking F's advancing foot with her own leg in front. F loses his support, first dropping to his knees on the concrete floor at the front of the classroom, then falling to the side. A immediately releases her grip and steps back, ensuring the hit and fall are clear and continuous, with no teleportation or contact-free falling. 22.30–25.00s: 24mm stable wide shot for the ending. A stands alone in the center of the classroom, with all traces of the fight preserved around her: B beside the shattered green lab bench at the rear right, C beneath the right wall, D lying among the wrecked central desks, E fallen onto the reading sofa on the left, F fallen in the foreground. Wooden chairs lie overturned; books, workbooks, chalk, glass, and paper are scattered across the floor. A lowers her head to roll up her alcohol-soaked left sleeve, tucks her loosened ponytail back behind her, then slowly raises her eyes to survey the classroom. The background adult students cautiously peek out from behind the back-row desks. In the final second, the camera pushes in extremely slowly. Only A's slightly heavy breathing, her gently swaying ponytail, the flickering fluorescent lights, and the chalk dust in the air are in motion. [Sound] An old ceiling fan, the electrical hum of fluorescent lights, and a distant low city rumble; the dull thuds of forearms and palms striking the body, wooden desks breaking, textbooks and the chalk box hitting the floor, chairs slamming against the wall, the glass bottle rolling, alcohol splashing, shoe soles scraping the concrete floor. The background adult students produce only brief startled gasps, chairs scraping back, and hurried footsteps — no exaggerated shouting is added. At the end, the sound narrows rapidly, leaving only the fluorescent light's electrical hum, the sound of the last book hitting the floor, and the protagonist's breathing. [Negative Constraints] No film titles, actor names, existing film/TV characters, school emblems, school names, legible chalkboard writing, subtitles, on-screen text, arrows, narration, watermarks, or instructional annotations; no minors may appear; no freeze-frames, slow motion, replays, anime-style effects, or superpowers; do not add extra attackers, and do not let any downed character get back up. Do not change the protagonist's face, body, black cap, low ponytail, or black outfit; do not let her hair suddenly come loose, or change hair color or length; do not portray the protagonist with sexualized posing, high-heel styling, or exaggerated model-like posturing. No face-swapping, duplicated characters, malformed limbs, extra fingers, clipping through geometry, teleportation, contact-free falls, or gravity-defying flight; do not let desks, wooden chairs, the bottle, books, or debris reset after a cut; no heavy blood spatter, dismemberment, or exposed organs — only F's slight blood trace at the corner of his mouth should remain. All actions are cinematic fictional choreography, and must not be presented as real-world instruction or a step-by-step training guide.
