ONE ARROW, SIX WORLDS.

[Material Roles]
@img1  defines the archer's face, hair, and clothing. Do not use its background or pose.
@img9  defines the opening location — its terrain, light, and the photographic tone of the entire video.
@img2  , @img3  , @img4  , @img5  , @img6  , @img7  , @img8  8 ALL define ONE single shape-shifting projectile. @img2 is its arrow form; @img3 its fire firebird form; @img4 its azure water dragon form; @img5 its antlered lightning beast form; @img6 its frost white tiger form; @img7 its jade-winged wind bird form; @img8 its golden three-legged sun crow form. These are seven forms of ONE single body. The video contains exactly ONE such projectile on screen at any moment. Do not use any reference image's background.

[Straight-Line Law]
The projectile flies in ONE straight, unwavering ballistic line from the bowstring to the final impact — constant heading, gently descending, like a real arrow shot once. It never turns, weaves, circles, spirals, banks, or reverses. Every world lies along this one straight line; every battlefield is crossed in a straight low pass; every veil between worlds sits directly ahead on the line. ALL visual playfulness belongs to the CAMERA, never to the flight path: the camera orbits the flying projectile, rolls around the line, swings ahead of it and falls back behind it, speed-ramps — while the projectile itself never deviates from its straight line.

[One-Take Law]
This is ONE unbroken continuous shot from first frame to last. No cuts, no editing, no dissolves, no flash frames, no white-flash or light-burst transitions of any kind. Passage between worlds is physical and happens inside the shot: the projectile punches straight through a natural veil directly ahead on its line — a cloud bank, a wall of dust, an ash cloud, a storm front — and the camera follows it through into the next world.

[Form Law]
Between worlds the projectile is in arrow form. Entering each world, its body ignites/erupts, stretches, and reshapes INTO that world's beast in one continuous on-screen morph — same body, same momentum, same straight line. From the instant the morph begins until it leaves that world, the arrow form does not exist: ONLY the beast is on screen. Leaving the world, the beast's body contracts back into the arrow form, again one continuous on-screen morph of the same body. Never show an arrow flying alongside, ahead of, beneath, or behind a creature. Never show a creature escorting, chasing, or carrying an arrow. One body, one form at a time, always.

[World Settings]
Live-action VFX realism throughout; the photographic tone and realism level set by @img9's opening carry through every world unchanged. All elemental effects are film-VFX physics — volumetric flame, simulated water, practical debris and dust, real light spill: heat shimmer above fire, drifting mist after water, hard lightning flashes with long real shadows, frost fog around ice. No video-game particle effects, no neon outlines, no glowing magic circles. Every battlefield holds ten thousand soldiers in formations stretching past the horizon, filling the frame edge to edge; every beast form is titanic, dominating the upper half of the frame while the soldiers read as tiny figures, so its devastation is physically believable. Each world's palette deliberately contrasts the current element: fire vs. blue ice, water vs. red desert, lightning vs. golden field, ice vs. black-red lava, wind vs. purple dusk, light vs. pitch darkness. Soldiers wear era-appropriate armor with varied faces, clothing tones, and unsynchronized movements like a real crowd; each world's devastation stays visible until the projectile leaves it. Armies from different worlds never mix. Nothing appears out of thin air.
Audio: diegetic sound only — wind, bowstring, creature roars, elemental impacts, battle noise. Absolutely NO background music, NO musical score, NO soundtrack at any point.
No subtitles, no on-screen text, no logo, no watermark.

[Timeline — one continuous shot; time ranges are pacing only, never cut points]
0-5 seconds: On the windswept basalt cliff above a sea of clouds (@img9), in cold pre-dawn light. Extreme close-up of the archer's (@img1) eye, the cloud horizon reflected in her iris. The camera pulls back and orbits her in a fast low-angle arc as she draws the bow to full tension, the arrow nocked on the string. At release, time briefly slows while the camera swings 180 degrees around the arrow mid-air, the bowstring's vibration rippling visibly <deep bowstring thrum>; time snaps back and the camera falls in right behind the arrow's fletching as it leaves the cliff on its straight, gently descending line toward the cloud sea ahead.

5-9 seconds: The arrow punches straight through the cloud bank and emerges above a vast glacial battlefield in cold blue-white dawn light — ten thousand armored soldiers clashing on the ice, ranks stretching past the horizon, arrayed directly across its line. Mid-flight its body ignites, stretches, and reshapes into the crimson-and-gold firebird (@img3) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. Its wingspan is wider than the entire formation below, a single wingtip taller than the siege banners. It makes one straight low pass THROUGH the clashing ranks, carving a straight molten glowing trench; rolling volumetric flames with black smoke and heat shimmer hurl soldiers aside like scattered grain <piercing firebird cry, roaring flames>. The camera swings from behind to alongside during the pass. At the far edge of the icefield its body contracts back into the burning arrow and punches into the towering wall of orange dust directly ahead.

9-13 seconds: Through the dust wall into a red desert canyon at sunset, the canyon's axis aligned with the arrow's line — ten thousand riders charging along the canyon floor. Its body bursts into water, stretches, and reshapes into the serpentine azure dragon (@img4) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. Its coils fill the canyon from wall to wall, its long body rippling behind its straight course; the riders beneath read like ants. It makes one straight low run above the charging column, a churning whitewater tidal wave with real spray and mist erupting beneath it and sweeping the cavalry off their feet <thunderous roar, crashing water>. The camera rolls once around the flying body. At the canyon's end its body narrows back into the water arrow and pierces the shimmering heat-haze curtain ahead.

13-17 seconds: Through the heat haze onto a golden wheat plain at high noon — ten thousand spearmen in dense formations directly across the line. Its body crackles, stretches, and reshapes into the antlered lightning beast (@img5) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. It is titanic: shoulders above the tallest war banners, the soldiers barely reaching its hooves. It gallops on air along the straight line, straight through the heart of the army at chest height; every hoofstep detonates forked lightning that floods the plain with hard white flashes and long real shadows, blasting soldiers off their feet and ripping a straight smoking corridor of violet scorch lines through the ranks — the formations visibly break and scatter along its track <rolling thunderclaps>. The camera drops low among the scattering soldiers looking up at it, then speed-ramps back in behind. At the plain's far edge its body condenses into the lightning arrow and enters the black ash cloud ahead.

17-21 seconds: Through the ash cloud into a volcanic battlefield — rivers of red lava under a black ash sky, ten thousand soldiers fighting along basalt ridges across its line. Its body crystallizes, stretches, and reshapes into the giant frost white tiger (@img6) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. Its shoulders are level with the basalt ridge, each paw print wide enough to swallow a shield wall. It sprints low along the straight line, just above the lava river and through the fighting ranks; everything along its straight corridor freezes solid in expanding fractal ice with audible cracking, soldiers locking mid-motion in frost, fog rolling off the frozen lava <sharp cracking ice, tiger roar>. The camera skims the freezing lava surface beside it. At the field's end its body condenses into the ice arrow and pierces the torn storm front ahead.

21-25 seconds: Through the storm front into a purple twilight mountain fortress under siege — ten thousand troops swarming walls that lie directly across the line. Its body spins into jade light, stretches, and reshapes into the vast jade-winged bird (@img7) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. Its wings are wider than the entire fortress wall, its passing shadow plunging the battlefield into darkness. It makes one straight pass directly over the walls; a debris-laden vortex of dust, splinters and torn banners rips along its straight track, toppling the siege towers like toys <howling gale, groaning collapsing timber>. The camera rolls once around the line. Beyond the fortress its body folds back into the arrow and enters the black night ahead.

25-30 seconds: Out of the night, the line now runs low over a pitch-black midnight battlefield lit only by scattered torches — ten thousand soldiers locked in chaos, and the ground rising to meet the gently descending line ahead. Its body blazes, stretches, and unfolds into the golden three-legged sun crow (@img8) in one continuous morph — same body, same momentum, same straight line; the arrow form is gone. Its wings spread like a second sky over the central formation; night turns to day as golden volumetric light washes over ten thousand upturned faces. Still on the same straight descending line, its wings fold and its body condenses into a pure golden arrow, and the arrow strikes the battlefield's center where the line meets the ground: a ring-shaped golden shockwave with a visible dust wall flattens everything outward in slow motion. Only the camera moves now — pulling up and away to reveal the full crater: the arrow planted upright at its center, six faint elemental afterimages (flame, water, lightning, frost, wind, light) spiraling slowly upward around it <one deep resonant impact boom, then ringing silence>.

[Maintain Consistency]
Exactly ONE shape-shifting projectile for the entire video — one body, one form at a time, never two, never a duplicate. Its path is one straight line from the bowstring to the crater. The archer appears only in the opening. Each beast form matches its reference image and keeps its titanic scale relative to the soldiers for its whole world. One continuous camera, one continuous shot, from the archer's eye to the final crater.
