騎士策馬飛奔過雪山環繞的冰封湖面，巨龍在冰下游動並使冰面碎裂

提示詞

超寫實電影感奇幻動作場景，15 秒，畫面比例 16:9。

白天，冰封的山野中。一名騎士騎著一匹快馬，疾馳越過遼闊的冰封湖面，而一頭巨龍正在下方的冰層底下移動。湖面覆蓋著積有薄雪的藍色冰層，上面有裂縫、受困的氣泡與霜凍紋路。嶙峋的群山與冰冷的懸崖環繞著湖泊。強風吹著鬆散的雪掠過湖面。危險來自下方：巨龍最初只呈現為冰層下移動的巨大暗影，接著牠行經之處的冰面開始龜裂、崩裂。

開場以俯瞰湖面的高空大幅環繞鏡頭呈現騎士與快馬疾馳越過開闊冰面的景象，朝遠方的岸邊前進。在他們下方，一道巨大的陰影掠過冰封湖面下方，從底下緊追著他們的路線移動。
切換至貼近冰面的低角度近景，拍攝馬蹄重重踏擊冰面的畫面。每次馬蹄落下，細如髮絲的裂縫便突然向外蔓延。馬匹稍微踉蹌，但仍繼續奔跑，騎士則向前傾身，催促牠加速。
切換至冰層下方的視角，透過半透明的藍色冰層向上觀看。巨龍的身影在冰面下方猛然竄動，牠的動作使冰層從下方扭曲變形。接著冰面隆起、裂開，巨龍也隨之更加逼近。

回到冰面上方，呈現劇烈的動態場面。長長的裂縫緊追在騎士身後。冰塊碎片向上飛濺，積雪炸散至空中，冰封湖面的一大片區域崩塌，墜入漆黑冰冷的湖水中。巨龍的角、吻部或發光的雙眼短暫地出現在龜裂的冰層下，隨即再次消失在藍色深處。

接近結尾時，騎士抵達岸邊前的最後一段路程，巨龍則在他正後方猛然竄起，將更大一片冰面撞得粉碎。馬匹躍過最後一道裂開的冰縫，重重落地在堅實地面附近，接著踉蹌衝上滿布岩石與積雪的岸邊，身後的碎冰隨即崩塌。
結尾呈現騎士在岸邊短暫轉身，而巨龍的龐大身影仍在湖岸附近碎裂的冰層下方移動，冰霧升騰至空中。

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

Daytime in a frozen mountain wilderness. One rider on a fast horse races across a vast frozen lake while a giant dragon moves beneath the ice below. The lake is covered in snow-dusted blue ice with cracks, trapped air, and frosted patterns. Jagged mountains and icy cliffs surround the lake. Wind drives loose snow across the surface. The danger comes from below: the dragon is visible first as a huge dark shape moving under the ice, then the frozen surface begins cracking and breaking in its path.

Begin with a high sweeping view of the lake as the rider and horse race across the open ice toward the distant shore. Beneath them, a massive shadow glides under the frozen surface, matching their path from below.
Shift to a close, low view near the horse’s hooves pounding the ice. Hairline cracks suddenly race outward under each stride. The horse stumbles slightly but keeps running as the rider leans forward, urging more speed.
Cut to a view from beneath the ice looking upward through blue translucent frozen layers. The dragon’s shape surges just below the surface, its movement distorting the ice from underneath. Then the ice bulges and splits as the creature rises closer.

Return above the surface with violent motion. Long fracture lines chase behind the rider. Ice shards jump upward, snow bursts into the air, and sections of the frozen lake collapse into dark freezing water. The dragon’s horns, snout, or glowing eyes become briefly visible under cracking ice before vanishing again into the blue depths.

Near the end, the rider reaches the last stretch before shore while the dragon surges up directly behind, smashing a larger section of ice apart. The horse launches across one final cracked gap, lands hard near solid ground, and scrambles onto the rocky snowy shoreline as broken ice collapses behind.
End with the rider turning briefly from the shore while the dragon’s huge shape moves beneath the shattered ice near the lake edge and freezing mist rises into the air.
