一列驶过历史的时间列车

30s竖屏9:16第一人称手机视频。一镜到底，无剪辑。廉价手机在拥挤的磁浮列车内以胸口高度手持，朝向左侧车窗外拍摄。画面晃动、歪斜、被肩膀遮挡，有卷帘快门效应、噪点，未经防抖。

列车始终向前行驶。全程是同一节车厢和同一批乘客。

0–2s 当今的城市。广播：“下一站：1944年。”列车颠了一下。

2–4s 真实的银灰色时间迷雾隧道吞没了城市。纸片和静电碎片飞掠而过。

4–8s 驶出后来到1944年6月的诺曼底（年份为1944）：灰色的黎明、舰船、登陆艇、烟雾、远处的士兵。无血腥暴力画面。

8–9s 再次进入迷雾。“下一站：1789年。”

9–13s 凡尔赛：金色的清晨、大门、马车、1789年的人群。

13–14s 迷雾。“下一站：1776年。”

14–18s 费城：独立厅、人群、宣言。一位乘客说 “Look.”

18–19s 暗色迷雾。“下一站：公元前1184年。”

19–23s 夜晚的特洛伊：燃烧的城墙、木马、舰船。只有剪影。

23–24s 沙尘迷雾。“下一站：公元前2500年。”

24–28s 吉萨：未完工的金字塔，数千名工人拖运石块。乘客低声说 “Ohh.”

28–30s 列车继续驶过金字塔。轻柔的广播：“欢迎来到公元前2500年。”自然结束。

仅有画内声音。通过左侧车窗，光线随每个时代而变化。每一次跳转都是真实的3D迷雾隧道，而不是剪辑。

30s vertical 9:16 first-person smartphone video. One continuous take, no cuts. Cheap phone held chest-height inside a packed maglev train, looking out the left window. Shaky, crooked, blocked by shoulders, rolling shutter, noisy, unstabilized.

Train always moves forward. Same carriage and passengers throughout.

0–2s Present day city. Announcement: “Next stop: 1944.” Train jolts.

2–4s Real silver-gray time-mist tunnel swallows the city. Papers and static fragments fly past.

4–8s Emerges at Normandy, June 1944: gray dawn, ships, landing craft, smoke, distant soldiers. No graphic violence.

8–9s Mist again. “Next stop: 1789.”

9–13s Versailles: golden morning, gates, carriages, 1789 crowds.

13–14s Mist. “Next stop: 1776.”

14–18s Philadelphia: Independence Hall, crowd, proclamation. A passenger says “Look.”

18–19s Dark mist. “Next stop: 1184 BC.”

19–23s Troy at night: burning walls, wooden horse, ships. Silhouettes only.

23–24s Sand mist. “Next stop: 2500 BC.”

24–28s Giza: unfinished pyramid, thousands of workers hauling stones. Passenger whispers “Ohh.”

28–30s Train keeps moving past the pyramid. Soft announcement: “Welcome to 2500 BC.” Ends naturally.

Diegetic sound only. Light changes with each era through the left window. Every jump is a real 3D mist tunnel, not an edit.
