Vex 博士在午夜鐘樓天文台喝下紫色藥劑，變身為駭人的怪物，Seedance 2.0 黑暗奇幻短片

提示詞

PROMPT 1 — "THE ELIXIR" (0–15 秒)

0–3 秒：外景建立鏡頭——午夜時分，鐘樓裡的天文台高聳於被濃霧吞沒的城市天際線之上，巨大的鐘面閃耀著紫色光芒。狂風呼嘯著掠過破裂的窗戶。鏡頭推向一扇發光的圓窗，接著無縫穿過玻璃，滑入天文台內部。裡頭齒輪嘎嘎作響，紫色火焰球在天花板附近懶洋洋地飄浮，星圖在圖釘上翻飛。

3–6 秒：鏡頭緩緩環繞，帶出站在螺旋樓梯平台上的 Dr. Vex；她身旁是一座巨大的黃銅星盤裝置。她舉起一只破裂的水晶瓶，裡頭旋流著銀紫色的靈藥，像欣賞寶石般端詳著它。她銀色的髮髻映著火光。她下方的 Milo 和 Senna 憂心忡忡地交換了一個眼神。

6–10 秒：她啪地一聲拔開瓶塞——紫色煙霧盤旋升起。她將瓶子舉向星盤，星盤呻吟著，旋轉得越來越快。鏡頭推近她的臉，呈現特寫；她神情平靜而篤定。她一口氣喝下靈藥。學徒們僵在原地，繃緊神經，做好準備。有一瞬間，什麼事也沒發生。她滿意地微笑，開始開口說話。

10–15 秒：她的笑容定格在臉上。四周一片寂靜。她的手指一根接一根地抽動。銀紫色的光在她喉嚨和下顎的皮膚底下如蛛網般蔓延。她的瞳孔縮成針尖般大小。頭頂的星盤猛然一震，迸出火花。房間裡每一顆紫色火焰球同時閃亮又黯淡。玻璃儀器在架上鏗鏘震動。她的脊椎伴隨一聲清脆的爆裂聲向後拱起。她的頭無力地垂下，接著緩緩抬起——雙眼如今變得乳白，嘴巴咧成一道寬得非人的笑容。低沉的磨刮聲般的咆哮在塔樓裡迴盪。學徒們踉蹌著退到欄杆旁。那個曾經是 Dr. Vex 的東西轉頭看向他們。

PROMPT 2 — "THE COUNTER-REAGENT" (15–30 秒)

15–18 秒：變異後的 Vex 以抽搐而不自然的動作，沿著剩下的幾級樓梯走向學徒們。她猛然撲上前，抓住 Milo 背心的領口，把他提得雙腳幾乎離地。他踢著腿，發出驚叫；護目鏡歪到一旁。

18–22 秒：Senna 的目光迅速掃過凌亂的工作檯，卻始終盯著 Vex。她在星圖之間發現一小瓶發光的琥珀色解藥——Senna 一直懷疑，那就是 Vex「以防萬一」調製的那瓶。她一手伸出，緩慢而無聲地朝它挪近。

PROMPT 1 — "THE ELIXIR" (0–15 seconds)

0–3s: Exterior establishing shot — the clocktower observatory looms over a fog-drowned city skyline at midnight, its great clock face glowing violet. Wind screams past cracked windows. The camera pushes toward a glowing round window, then glides seamlessly through the glass into the observatory. Inside, gears grind, orbs of violet fire drift lazily near the ceiling, star charts flutter on their pins.

3–6s: Camera circles slowly to reveal Dr. Vex standing atop a spiral staircase platform beside a massive brass astrolabe rig. She holds up a swirling silver-violet elixir in a cracked crystal flask, admiring it like a jewel. Her silver topknot catches the firelight. Below her, Milo and Senna trade a worried glance.

6–10s: She uncorks the flask with a sharp crack — violet smoke coils upward. She lifts it toward the astrolabe as it groans and spins faster. Camera pushes into close-up on her face, calm and certain. She drinks it in one motion. The apprentices freeze, bracing. Nothing happens for a beat. She smiles, satisfied, and begins to speak.

10–15s: Her smile locks in place. Silence. Her fingers twitch, one by one. Silver-violet light spiderwebs beneath the skin of her throat and jaw. Her pupils contract to pinpricks. The astrolabe overhead lurches and sparks. Every violet flame-orb in the room flares and dims in unison. Glass instruments rattle off their shelves. Her spine arches backward with a sharp crack. Her head lolls, then rises slowly — eyes now milky white, mouth stretched into a grin too wide to be human. A low, grinding growl rolls through the tower. The apprentices stumble back against the railing. The thing that was Dr. Vex turns its head toward them.

PROMPT 2 — "THE COUNTER-REAGENT" (15–30 seconds)

15–18s: The transformed Vex descends the last few stairs toward the apprentices, movements jerky and unnatural. She lunges and seizes Milo by the vest collar, hoisting him half off his feet. He kicks and yelps, goggles askew.

18–22s: Senna's eyes dart across the cluttered workbench without breaking her stare on Vex. She spots a small vial of glowing amber counter-reagent tucked among the star charts — the one Vex brewed "just in case," Senna always suspected. She edges toward it, slow, silent, one hand out.
