身穿銀黑色生物機械戰甲的駕駛員在水下遺跡中閃避史前海洋掠食者，時長 15 秒

提示詞

15s, 16:9, 超寫實水下科幻動作電影，電影級真人實拍 VFX，深藍色混濁海洋遺跡，漂浮粒子，氣泡，體積光束，斷裂金屬樑柱，巨大的圓形沉沒結構，無文字，無浮水印，無卡通，無遊戲 UI。

角色鎖定：
僅使用 Image 1 作為 Alin 的參考。保留她完全一致的臉部特徵、長而淡金色的頭髮、銀黑色女性生化機械裝甲、橘色發光細節、流線型全身戰鬥服、寫實金屬關節、鮮明的女性身形輪廓。她是一名高科技水下戰鬥飛行員，不是普通潛水員。

怪物鎖定：
僅使用 Image 2 作為海怪參考。保留完全一致的史前水生掠食者設計：狹長的鱷魚頭骨、巨大的嘴巴、密集銳利的牙齒、深色濕潤皮膚、粗重的頸部、四隻鰭肢、長尾巴、寫實海洋爬蟲身體。不要觸手，不要章魚生物，不要抽象陰影怪物。

節奏：
快速進場 -> 短暫鎖定 -> 掠食者突然掠過 -> 險些死亡的閃避 -> 近距離反擊 -> 黑暗懸疑結尾。

0.0-1.5s
快速向前俯衝進入水下遺跡。Alin 穿過氣泡與斷裂樑柱疾速前進，身後拖曳著藍色推進器軌跡，進入巨大的沉沒結構核心。

1.5-3.8s
她在巨大圓形遺跡入口前減速並穩定身體。她的前臂裝甲展開成兩把發光的藍色能量刃。她察覺到附近有異狀。

3.8-6.0s
怪物巨大的身影突然高速從她身後掠過。水流將她猛地撞向側方。只有頭部、背部和尾巴的部分輪廓能被清楚看見，牠疾速掠過。

6.0-8.2s
強烈危機節拍。怪物張開大嘴猛撲而來。Alin 在最後一刻下沉並扭身穿過牠的嘴下與前鰭，同時在逃脫時以藍色能量刃在牠的頸部劃出一道短促的能量傷痕。

8.2-11.5s
她翻身重新掌控局面，推進器啟動，雙臂交叉蓄力，胸口與前臂爆發明亮光芒。她以一次殘酷的近距離藍白色脈衝斬擊擊中怪物，將氣泡、淤泥與碎屑向外轟散。

11.5-13.6s
怪物被逼退至遺跡的黑暗深處，沒有被殺死，只是被迫退開。Alin 保持位置，雙刃仍處於啟動狀態，準備迎接下一次攻擊。

13.6-15.0s
最終懸疑鏡頭。攝影機緩慢拉遠。Alin 飄浮在前景，背對攝影機。在她身後的深邃黑暗中，怪物的頭部與牙齒緩慢重新出現，預示第二回合即將開始。

光線：
冰冷的深海藍，高對比，寫實的水下散射，銳利的藍色能量閃光，微弱的橘色裝甲光芒，黑暗深淵的壓迫感。

聲音：
深水轟鳴，氣泡聲，推進器嘯聲，裝甲展開的喀噠聲，怪物排開水流的聲音，沉重的水下啃咬撞擊聲，尖銳的能量蓄力聲，沉悶的衝擊波。

負面：
不要觸手，不要額外生物，不要血腥暴力，不要一擊必殺，不要明亮的幻想色彩，不要僵硬的漂浮姿勢，不要解剖結構變形。

15s, 16:9, ultra-realistic underwater sci-fi action film, cinematic live-action VFX, deep blue murky ocean ruins, floating particles, bubbles, volumetric light shafts, broken metal beams, giant circular submerged structure, no text, no watermark, no cartoon, no game UI.

Character lock:
Use Image 1 as the only reference for Alin. Keep her exact face, long pale blonde hair, silver-black female biomechanical armor, orange glowing details, sleek full-body combat suit, realistic metal joints, strong feminine silhouette. She is a high-tech underwater combat pilot, not a normal diver.

Monster lock:
Use Image 2 as the only sea monster reference. Keep the exact prehistoric aquatic predator design: long narrow crocodilian skull, huge mouth, dense sharp teeth, dark wet skin, heavy neck, four flippers, long tail, realistic marine reptile body. No tentacles, no octopus creature, no abstract shadow monster.

Rhythm:
Fast entry -> brief lock-on -> sudden predator pass -> near-death dodge -> close-range counterattack -> dark suspense ending.

0.0-1.5s
Fast forward dive into the underwater ruins. Alin rushes through bubbles and broken beams with blue thruster trails, entering the core of a giant submerged structure.

1.5-3.8s
She brakes and stabilizes in front of a huge circular ruin opening. Her forearm armor unfolds into two glowing blue energy blades. She senses something nearby.

3.8-6.0s
A massive shadow of the monster suddenly cuts behind her at high speed. The water current slams her sideways. Only parts of the head, back, and tail are clearly seen as it rushes past.

6.0-8.2s
Hard danger beat. The monster lunges with jaws wide open. Alin drops and twists beneath its mouth and front flipper at the last second, slicing a short blue energy scar across its neck as she escapes.

8.2-11.5s
She flips back into control, thrusters fire, arms cross to charge, chest and forearms flare bright. She delivers one brutal close-range blue-white pulse slash into the monster, blasting bubbles, silt, and debris outward.

11.5-13.6s
The monster is driven back into the darkness of the ruin, not killed, only forced away. Alin holds position with both blades still active, ready for the next attack.

13.6-15.0s
Final suspense shot. Camera slowly pulls back. Alin floats in the foreground with her back to camera. In the deep darkness behind her, the monster’s head and teeth slowly reappear, signaling round two is about to begin.

Lighting:
Cold deep-sea blue, high contrast, realistic underwater scattering, sharp blue energy flashes, faint orange armor glow, dark abyss pressure.

Sound:
Deep water rumble, bubbles, thruster whine, armor deployment clicks, monster water displacement, heavy underwater bite impact, sharp energy charge, muffled shockwave.

Negative:
No tentacles, no extra creatures, no blood gore, no one-shot kill, no bright fantasy colors, no stiff floating pose, no distorted anatomy.
