戴頭盔的騎士在夜間隧道中疾馳，身後洪水洶湧而來

提示詞

超寫實電影感動作場景，15 秒，長寬比 16:9。

夜晚，在大型地下維修隧道內，一名騎士騎著流線型高速重機向前疾馳，身後則有一股洶湧的洪水灌入隧道。環境呈現清晰的工業風格：混凝土隧道牆壁、上方管線、支撐樑、維修燈、金屬走道、警示燈，以及潮濕且具有反光效果的表面。
騎士穿著深色合身騎士裝，戴著深色面罩的全罩式安全帽。看不見臉部。

廣角開場鏡頭：騎士高速穿越維修隧道。遠處後方，一道洪水牆猛然灌入隧道，開始迅速向前湧來。隧道燈光映照在濕滑地面上。
側面跟拍鏡頭：騎士在隧道中加速，身後的洪水不斷逼近。重機在支撐柱、管線和簡單的維修障礙物間穿梭。騎士經過時，隧道燈開始依序一盞接一盞熄滅。

前方三分之四角度鏡頭：水位升高並蔓延至地面，騎士仍持續高速前進。輪胎周圍濺起水花。警示燈閃爍紅光。
遠處隧道盡頭可見正在關閉的防洪閘門。

最後 5 秒：節奏變得更加緊張。洪水不斷逼近，騎士將速度催至極限。更多隧道燈熄滅。騎士壓低身體，疾速穿過逐漸縮小的開口，在沉重的防洪閘門完全關閉前一刻脫身。另一側的洪水猛烈撞上閘門。
最後一刻：騎士在閘門後方較安全的通道內打滑後停下，洪水則在身後猛烈撞擊已密封的屏障。

風格：超寫實、電影感、快節奏，強烈呈現緊迫感與速度感，動作清晰易懂，工業隧道氛圍、上漲的水位、閃爍的警示燈、倒影、水花，動態但清楚易懂的鏡頭運動，不露出臉部，不要與名人相似，不要文字，不要標誌，不要卡通風格，不要慢動作。保持比例。保持風格與特徵。長寬比 16:9。

Hyper-realistic cinematic action sequence, 15 seconds, aspect ratio 16:9.

Inside a large underground maintenance tunnel at night, a rider on a sleek fast bike races forward as a violent surge of water floods through the tunnel behind them. The environment is industrial and clear: concrete tunnel walls, overhead pipes, support beams, service lights, metal walkways, warning lights, and wet reflective surfaces. 
The rider wears dark fitted riding gear and a full helmet with dark visor. No visible face.

Wide opening shot: the rider speeds through the maintenance tunnel at high speed. Far behind, a wall of floodwater bursts into the tunnel and begins rushing forward. Tunnel lights reflect on the wet ground.
Side tracking shot: the rider accelerates through the tunnel while water surges closer behind. The bike weaves past support pillars, pipes, and simple maintenance obstacles. The tunnel lights begin failing one by one, going dark in sequence as the rider passes.

Front three-quarter shot: the rider keeps moving fast as water rises and spreads across the floor. Spray kicks up around the tires. Warning lights flash red. 
The closing flood gate is visible far ahead at the end of the tunnel.

Final 5 seconds: the pace becomes more intense. The rider pushes to maximum speed as the floodwater closes in. More tunnel lights go dark. The rider leans low, races through the narrowing opening, and escapes just before the heavy flood gate finishes closing. The water slams into the gate from the other side.
Final moment: the rider skids to a stop in the safer corridor beyond the gate while water crashes against the sealed barrier behind.

Style: hyper-realistic, cinematic, fast-paced, strong sense of urgency and speed, clear readable action, industrial tunnel atmosphere, rising water, flashing warning lights, reflections, spray, dynamic but readable camera movement, no visible face, no celebrity resemblance, no text, no logos, no cartoon style, no slow motion. Keep proportions. Keep style and features. Aspect ratio 16:9.
