[00:00-00:04] Shot 1: Epic Opening
Low-angle tracking shot: @Image1 stands on a floating silver sword, gliding smoothly two meters above the road. Her dress and hair flow backward in the wind, hands behind her back, chin slightly tilted with a master's poise.
Audio: Xianxia-style whistling wind + sword hum.

[00:04-00:08] Shot 2: Dialogue Beat
Medium tracking shot: @Image2 is cycling in the non-motorized lane, looks up at @Image1, eyes wide, and pedals hard to catch up.
[Lines/Subtitles] @Image2 shouts: "Wow! Sister, you are amazing!!"
Close-up: @Image1's mouth curls into a proud smile which she tries to suppress, reservedly brushing her hair while the sword below playfully carves an S-curve.
Audio: Proud humming sound effect.

[00:08-00:11] Shot 3: The Twist
Wide side shot: While @Image1 is feeling herself, a blue truck zooms past from the right. The wind gust flips her off the sword; her expression shifts from pride to shock as she and the sword crash into the roadside cardboard boxes, which scatter everywhere.
Audio: Truck horn + box crashing + crow cawing sound effects.

[00:11-00:15] Shot 4: Punchline
Close-up: @Image2 brakes with one foot, stunned for three seconds, then slowly holds the handlebar with one hand.
Extreme close-up: @Image1 sits up from the boxes with a lid on her head, messy hair, and a dazed look. The sword clangs down beside her.
[Lines/Subtitles] @Image2 stifles a laugh: "Sister... you're impressive, but you really should watch the road."
Freeze frame on @Image1 rolling her eyes under the box lid, ending with a funny laughter sound effect.
