15-second high-octane Chinese martial arts 2D animated film, mature-oriented Guoman, 2D hand-drawn cel animation texture, realistic adult body proportions, clear outlines, Level 2-3 hard-edged shadows, cinematic lighting and shadows, partial integration of ink splash/streaks, high-speed brushes, smear frames, air blade cuts, and exaggerated yet logically consistent high-speed afterimages. Not Xianxia, not a game skill showcase, the core is a realistic martial arts chase under extreme speed differences. Setting: 'Duanyun Temple' at dusk just after heavy rain, a massive abandoned ancient temple nestled among mountains and cliffs. Features a three-story wooden main hall, giant dark brown wooden pillars, dark blue-black wet tiles, half-collapsed corridors, stone courtyards, a bell tower, broken railings, a stone bridge over a cliff, ancient pines, and tattered Buddhist banners. The western dark clouds split to reveal an orange-red sunset, with warm golden slanted light illuminating the cold bluish-gray temple. Wet stone slabs and tiles reflect characters and special effects. The air is filled with mist, dust, falling leaves, and broken tiles. Character A: 'Bai Jin', a white-haired thread-suspending guest, adult male, slender and lean, long silvery-white hair, black narrow-sleeved cross-collar martial arts attire, dark black short robe, dark red waist sash, black leg-binding pants with light martial arts boots. Small amount of dark purple vein-like patterns on the side of the neck and chest. Combat ability: extreme high-speed Qinggong 'Purple Lightning Wandering Dragon Steps', vein-severing palm techniques, and heavy leg strikes 'Cloud-Severing Mountain-Cleaver'. Purple effects represent high-speed movement only, not energy attacks. Character B: 'Shen Yan', a black-clad bladesman, adult male, messy mid-length black hair, ink black and dark gray narrow-sleeved martial arts outfit, gray-black short cloak, a long saber in a deep black scabbard at his waist. Skilled in hidden blade techniques and judgment-based tile-treading footwork, but significantly slower than Bai Jin. He remains suppressed throughout the first half. 0.0—1.0s: Fight starts immediately. 20mm ultra-wide low-angle shot, camera almost touching the wet bluestone ground. Bai Jin occupies the massive foreground, one black boot appearing huge due to perspective, body lowered almost to the ground. Shen Yan stands in the courtyard in front of the main hall dozens of meters away. Bai Jin suddenly explodes off the ground; the stone slab beneath him cracks like a spiderweb, standing water splashes backward in a fan-shaped curtain, his hair and clothing pull straight back. The camera follows closely, with wooden pillars, stone steps, banners, and eaves blurring into high-speed stripes along the direction of motion. Bai Jin enters 'Purple Lightning Wandering Dragon Steps', forming a continuous high-speed trail with a white-purple highlight core, deep purple body, magenta edges, and minimal cyan-green dispersion. 1.0—2.5s: Bai Jin cuts into the courtyard at high speed but doesn't attack immediately. He first flashes past Shen Yan's left, leaving a black human afterimage, a white air trail, and water cut by the airflow; an instant later, he circles a giant wooden pillar from the right rear. Shen Yan quickly turns his head to find the target, hand gripping the hilt but not swinging wildly. The camera zooms into Shen Yan's eye; the pupil darts left, then snaps right. In the next frame, Bai Jin has already cut in from the side-rear. Bai Jin uses two joined knuckles to quickly brush aside Shen Yan's raised scabbard, followed immediately by a palm strike exploding from a very short distance, slamming heavily into the side of Shen Yan's face. The contact must be clear: the cheek compresses first, the head is knocked aside, hair and rain spin in the other direction, a few drops of blood fly out, and the shoulders and waist follow. The arm can have a very brief 2D smear stretch, but the actual arm does not lengthen. 2.5—4.0s: Shen Yan is sent flying dozens of meters laterally by the palm strike, body tumbling irregularly. His feet first brush against a stone lamp, shattering the top half, then he crashes through the decayed wooden railing and wall of the main hall. A massive amount of wood chips, tiles, and dust scatter. The camera cuts to an ultra-wide shot to show the displacement. Shen Yan's shoulders and back hit the wooden floor of the hall first, his body continuing to roll, the long saber still gripped in his hand, the scabbard scraping the floor creating continuous wood shavings. Finally, Shen Yan kneels on one knee, one hand supporting the ground, not yet fully stable. 4.0—5.8s: A purple-white high-speed light trail flashes outside the main hall's wooden wall. Bai Jin bursts through the wood chips into the hall, first flashing past Shen Yan's front, creating two purple human afterimages, then a third afterimage appearing behind Shen Yan. The real Bai Jin finally stops steadily to the side. As Shen Yan turns, Bai Jin has already stepped forward, his supporting foot crushing the floorboards, his knee lifting quickly, waist and hips fully rotating, his leg extending horizontally to execute 'Cloud-Severing Mountain-Cleaver'. His sole strikes Shen Yan's chest and abdomen heavily. At the moment of contact, Shen Yan's torso folds, the sword hilt is pressed into his body, and then his feet leave the ground entirely. 5.8—7.1s: Shen Yan is blown out from the other side of the hall by the side kick, the decayed wall exploding into a giant hole. He flies through a storm of wood pieces and broken tiles toward the next roof level. Shen Yan's feet hit the wet blue tiles first, which shatter consecutively as his body slides down the slanted roof at high speed. He immediately stabs the scabbard into the tile gaps to slow down, carving a long mark across the roof. Bai Jin doesn't pause, entering 'Purple Lightning Wandering Dragon Steps' again, shooting out from the hall's opening, a purple-white high-speed trail streaking across the flying eaves. 7.1—9.0s: High-density 3D pursuit. Bai Jin sprints along the eaves, circles behind an ancient pine, then runs briefly horizontally along the side wall of the bell tower, using the force to change direction. The purple light band forms a continuous S-shaped path between temple buildings, accompanied by black humanoid afterimages and white ink-style air brushes. Shen Yan leaps from a roof toward another corridor. Bai Jin cuts in early from the ridge above, first slamming his shoulder into Shen Yan's sword arm to deflect his posture, then immediately spinning his body to deliver a lateral elbow strike to the side of Shen Yan's face. The elbow strike frame features a strong 2D smear, with hair, cuffs, and forearm briefly stretched. Shen Yan is knocked off the roof again. 9.0—10.0s: Shen Yan falls from a height of two stories. Bai Jin chases down from above as an almost vertical purple high-speed trail. Bai Jin is not firing energy but descending at high speed himself. He passes Shen Yan mid-air, presses his palm against Shen Yan's back, and uses his own descending momentum to slam him downward. Shen Yan's trajectory is forced vertically down, crashing face-first into the next courtyard. The wet stone slabs shatter instantly, with white-gray dust, water splashes, and rubble exploding simultaneously, forming a tall smoke pillar in the center and a ring of spreading water curtains. 10.0—11.8s: Before the dust clears, Shen Yan forces himself out, running along a massive colonnade. Bai Jin follows in 'Purple Lightning Wandering Dragon Steps'. High-speed horizontal tracking shot; the two weave between dozens of giant dark brown wooden pillars, characters briefly obscured by the columns. The purple trail must realistically circle the pillars and never pass through them. Bai Jin kicks off a pillar to turn, wood chips exploding from the surface as he launches in the opposite direction. Shen Yan uses his scabbard to vault over a wooden railing, landing on an outer stone terrace. As Bai Jin chases out, the high-speed wind pressure sweeps up a whole row of banners. 11.8—13.2s: Shen Yan judges that the next strike cannot be fully dodged. He turns immediately, keeping his long saber sheathed, gripping both the hilt and scabbard with both hands, holding the entire sword horizontally across his chest, lowering his center of gravity in a front-back bow stance to form 'River-Blocking Guard'. In the distance, Bai Jin charges along the stone terrace, exiting the purple high-speed state in the final meters, pulling both palms to his waist before thrusting forward simultaneously in the final step with 'Mountain-Shaking Palm'. Both palms slam into Shen Yan's horizontal scabbard. 13.2—14.1s: The collision must be depicted in layers. In the first instant, Shen Yan successfully blocks the attack; the scabbard bends inward, his arms are pressed back to his chest by the immense force, and his feet slide back along the wet stone slabs, soles kicking up water splashes as the stones begin to crack. But Bai Jin's force continues to surge in; in the next instant, Shen Yan's defense completely collapses, and he is blown away along with his sword. The camera follows Shen Yan with a 30-45 degree camera roll, with eaves, sunset, cliffs, and mountains rotating and tilting together. 14.1—15.0s: Shen Yan flies toward an ancient stone bridge connecting two cliff walls. One foot touches the wet bridge surface first, followed by the second. His body continues to slide back at high speed, water on the bridge spraying to both sides. Shen Yan almost falls off the edge of the bridge before finally stabbing the scabbard into a stone crack; rubble bursts out, and his body finally forces a stop. The final shot is static: Shen Yan kneels on one knee in the center of the cliff stone bridge, head slightly lowered, a trace of blood at the corner of his mouth, shoulders heaving, one hand still firmly gripping the hilt. In the distance, on the roof of Duanyun Temple, Bai Jin stands quietly. The sunset stretches a vast distance between the two. The scene ends as Shen Yan just begins to look up, connecting directly to the next segment. Special Effects Fixed Rules: Purple only represents Bai Jin's high-speed Qinggong; white-purple center, deep purple body, magenta outer edge, minimal green dispersion. High speed can produce 3-5 humanoid afterimages, but there is only one real person. Attacks are primarily actual fist, palm, and leg techniques; effects only show speed and impact. All knockbacks must involve real contact first, then body deformation, then displacement. No random teleporting, no static standing, no turn-based combat, no purple turning into lasers, no characters passing through pillars or walls, no characters flying away prematurely, no instant recovery to normal after landing.
