Bamboo Forest Flying Knife Duel

First segment: Referring to the character movements and camera techniques in @Video 1, generate a video of the woman in black throwing a flying knife in the bamboo forest, as shown in @Image 1. Only the woman in black is featured in this video. The starting frame's perspective and framing should strictly follow @Video 1. After the knife is thrown, focus on the knife in slow motion and blur the woman in black. Note that the knife should fly towards the camera with the blade facing outwards, achieving a 1:1 recreation of the reference video, only changing the character to a woman in black. Only generate fighting and environmental sound effects; do not add background music. Second segment: Referring to the perspective and camera techniques of the flying knife in @Video 1, generate a video of a flying knife flying forward. The knife's perspective gradually zooms in to show the woman in @Image 1 practicing swordsmanship in the forest, using her sword to block the flying knife. Only the woman in blue is featured in this video. Again, maintain the starting frame's perspective and camera techniques strictly following @Video 1. Only generate fighting and environmental sound effects; do not add background music.
