[Generation Mode and Total Requirements]

Must use Seedance 2.0 Fast, strictly generate a full 15-second video, 16:9 widescreen, three continuous clear shots, with native synchronized Mandarin dialogue.

Master-level cinematic realistic texture, Arri Alexa film camera look, with a restrained and poetic Xianxia deadpan comedy temperament. The image is sharp and clear, volumetric morning light is naturally visible, acting is restrained, character movement is realistic but cinematic, and silk fabric, hair, paper, water flow, mountain mist, and natural light have believable physical feedback.

Adopting the 'Reference Image-Driven Living World System': All reference images together determine the location and visual world, including topographic logic, architectural language, spatial scale, material age, vegetation ecology, water flow direction, weather state, cloud movement, main light direction, reflective surfaces, comprehensive colors, and atmospheric depth. Before official generation, complete a round of environmental planning silently, reorganizing a new, unified, physically reasonable space from these common environmental DNAs.

The background must be vivid, unique, and continue to operate naturally, but only responsible for environmental presence, not actively triggering punchlines, changing character goals, or stealing the center of the plot.

[Characters and Core Props]

Character ID A | Swordmaster Senior Sister
Always the same 25-30 year old East Asian female from @Image 1, strictly maintaining the same face, oval face shape, fair natural skin tone, dark almond eyes, black long hair half-tied, white jade hairpin, tall and slender body proportions, white embroidered silk Hanfu, semi-transparent layered wide sleeves, silver waist seal, jade pendant, and white cloth boots.
Character ID B | Junior Sister
Always the same 20-25 year old East Asian female from @Image 2, strictly maintaining the same face, rounded and lively face shape, black hair braided, petite body proportions, green linen Hanfu, dark waist belt, wooden hairpin, and black cloth shoes.

Core Prop
Only one and the same sealed bamboo scroll throughout. The position, opening state, and holding relationship of the bamboo scroll in the three shots must be continuous and stable.

[0–5s | Low-angle panorama, slow track]

The mountain gate corridor stone platform on a morning after rain. Below is a sea of clouds and a valley, carved stone railings, wet slate, narrow canals, ancient pines, light-colored flowering branches, distant tiled palaces, slowly wandering mountain mist, and continuously changing wetland reflections together establish a real, breathing environment.
The same white-clad swordmaster senior sister and the same green-clad junior sister are located on both sides of the stone table.

The white-clad senior sister gently puts the same sealed bamboo scroll on the stone table between them, saying calmly:

'Three years ago, you left something behind. Today it is returned.'

The environment maintains restrained motion: the canal flows continuously, the mist slowly passes through the corridor, branches and hems respond to the same morning breeze, and the reflection on the stone surface after the rain changes naturally with the camera track.

[5–10s | Cowboy shot within a shot]

The same green-clad junior sister slowly reaches out to take the same bamboo scroll, while her other hand naturally rests by her sword.

The same white-clad senior sister maintains a completely calm expression and adds a sentence:

'I have already graded it for you.'

Nearby leaves naturally drift past the screen, forming realistic foreground parallax; the canal continues to flow, and mountain mist slowly wanders between the corridors.

The background always maintains only a sense of world presence and does not actively create new plot events.

The junior sister starts to unfold the bamboo scroll after taking it, maintaining continuous action for the next shot.

[10–15s | Close-up to extreme close-up]

The same bamboo scroll is fully unfolded.

Inside is not a secret manual, but an old love poem written by the same green-clad junior sister three years ago; the paper is densely written with neat, elegant red annotations.

The same green-clad junior sister freezes instantly and asks in a low voice:

'You read it all?'

The same white-clad senior sister answers calmly:

'I also changed three rhyme schemes; the third line is the best.'

An extreme close-up captures the junior sister's ears turning noticeably red.

The senior sister remains dignified, calm, and without any hint of mockery.

At this moment, a drop of rain from the eaves naturally falls into the same canal, making a slight and clear water sound, as the final deadpan beat.

Strictly ends at 15.0 seconds.
