Cinematic Wuxia Swordswoman with Synchronized Echoes

[Generation Mode] Seedance. First generate a 0–10 second clip, then based on that clip and its final frame, continuously extend for another 5 seconds. Total duration 15 seconds. [Screen Specifications] 16:9 widescreen, cinematic realistic texture, native synchronized Mandarin dialogue, no subtitles, only two visible characters throughout. [Overall Style] Cinematic realistic texture featuring monumental pure Chinese Xianxia architecture, restrained deadpan comedy, strong spatial sound narrative, warm sunrise piercing through cold blue-white cloud seas, weathered giant stones, dark ancient tile roofs, ivory silk, and fine film grain; the suspense is ultimately resolved through a comedic reversal within the grand scene. [Background Reference] @Image1–@Image4 used only for background and location, never for characters. Strictly preserve: giant circular celestial gate, layered rooftops of the immortal city above the clouds, mountain-scale stone pillars, dense rolling cloud seas, sunrise direction, grand spatial depth, and incredible vertical scale. [Character Settings] Character A (Senior Sister Sword Immortal): 26–30 years old, East Asian sword immortal woman, oval fair face, slender dark eyes, long black hair partially tied with a white jade hairpin, tall and slender, wearing white embroidered silk Hanfu with semi-transparent layered wide sleeves, silver waistband, jade pendant, and white cloth boots; carries a single slender silver flying sword. Character B (Junior Sister): 20–24 years old, East Asian junior sister, round and lively face, black hair in braids, small stature, wearing green linen Hanfu, dark waistband, wooden hairpin, and black cloth shoes. [Shot Design] Shot 1 (0–5s, Wide/Long Shot): 24mm aerial shot slowly pushing toward the giant celestial gate. Character A floats on a silver flying sword three meters above a stone platform, with the Junior Sister standing behind. The Senior Sister shouts deeply toward the gate: 'Guardian of the Celestial Gate, show yourself!' The circular gate immediately echoes back with clear spatial positioning: 'Show yourself—self—' Shot 2 (5–10s, Medium/Cowboy Shot): Character A lands back on the platform, Junior Sister remains behind, background stays consistent. The Senior Sister narrows her eyes, half-drawing her sword, and says coldly: 'Do not hide your head and show your tail.' The gate echoes back: 'Show your tail—tail—.' Wuxia-style zither and sword ring rise; she takes a restrained, precise defensive stance. Shot 3 (10–15s, Close-up/Extreme Close-up): The 5-second extension must continue from the final frame of the 10-second clip, maintaining total continuity of camera axis, character positions, sun direction, cloud movement, architecture, sword, and clothing. The Junior Sister walks up and says calmly: 'Sister, that is just an echo.' She then cups her hands and shouts: 'Senior Sister loves saving face the most!' The gate boisterously repeats: 'Saving face—face—.' The Senior Sister slowly sheaths her sword and whispers: 'This door is too talkative.' The gate echoes again: 'Talkative—tive—.' The shot ends on her face trying to maintain dignity but completely frozen, one eyebrow twitching slightly; the Junior Sister turns away, silently stifling a laugh. [Continuity Requirements] Generate 0-10s first, then use it as a reference to extend the last 5s. [Technical Requirements] 15s total, 16:9, sync Mandarin dialogue, spatial echo with long reverb, natural movement for clouds/silk/hair/sword, no subtitles, two characters only. [Negative Prompts] blurry, bad quality, low quality, low resolution, noisy, jpeg artifacts, watermark, text, error; deformed, mutated, bad anatomy, poorly drawn hands, bad composition, out of frame, disfigured; inconsistent character, changing clothes, face morphing, background shift, glitching cuts, disappearing props

电影级写实质感，采用纪念碑级纯中式仙侠建筑、克制的冷面喜剧、强烈空间声音叙事、温暖朝阳穿透清冷蓝白云海、风化巨石、深色古建瓦顶、象牙白真丝与细腻胶片颗粒；悬疑最终通过宏大场景本身完成喜剧反转。

巨型圆形天门
层层叠叠的云上仙城屋顶

山岳尺度石柱

浓密翻涌云海

【角色设定】
角色 A｜剑仙师姐
26–30 岁的东亚剑仙女子，椭圆白皙面庞，细长深色眼睛，黑色长发半挽，以白玉簪固定，身材高挑纤细，穿白色刺绣真丝汉服、半透明分层宽袖、银色腰封、玉佩、白色布靴，唯一一柄细长银色飞剑。
角色 B｜小师妹
同一个 20–24 岁的东亚小师妹，圆润灵动的脸，黑发编辫，身形娇小，穿青绿色亚麻汉服、深色腰带、木簪和黑色布鞋。
【镜头设计】
镜头 1｜0–5s｜全景 / 远景
24mm 航拍缓慢推向巨大天门。
角色 A 踩着同一柄银色飞剑悬浮在石台上方三米处，同一个小师妹站在后方。
剑仙师姐朝巨大天门沉声喝道：
“天门守将，现身！”

圆形巨门内部立刻传回浑厚而具有明确空间方位的回声：

“现身——身——”

镜头 2｜5–10s｜中景 / 牛仔景

同一个穿白色真丝汉服的剑仙师姐落回同一座石台，同一个小师妹仍然保持在后方，背景始终保持同一座巨型天门与同一片云上仙城。
剑仙师姐眯起双眼，将同一柄长剑拔出一半，冷声说道：
“莫藏头露尾。”

巨门再次以巨大回声回应：
“藏头露尾——尾——。”
英雄式古琴与剑鸣逐渐升起，她摆出克制而精准的戒备姿势。

镜头 3｜10–15s｜特写 / 极近特写

后 5 秒延长必须从前 10 秒成片的最后一帧原位继续，严格保持：

摄影机轴线完全连续

两名角色位置完全连续

太阳方向完全连续
云层运动完全连续

建筑结构完全连续

飞剑完全连续

服装完全连续

同一个小师妹走到她身旁，平静说道：

“师姐，那只是回声。”

随后双手拢在嘴边，对着天门大喊：

“师姐最爱面子！”
整座巨大天门立刻轰然重复：
“爱面子——子——。”
同一个剑仙师姐缓慢将长剑归鞘，低声说道：
“此门，多嘴。”
巨门马上再次回荡：
“多嘴——嘴——。”

镜头停在她努力维持端庄、高深却彻底僵住的脸上，一侧眉毛轻轻抽动；同一个小师妹转开脸，默默憋笑。
