纯粹是想试试极端近景能顶到什么程度，镜头几乎贴到刀刃上。难点是刀身的蓝光和周围的雪、烟三者会互相吃，写的时候得给每一层各自的存在感，尤其烟不能满屏，不然刀就消失了。人脸只留了半边在景深外，反而更有劲。
CG, CGI, unreal engine render, 3D, ultra realistic, extreme close up macro shot on a chinese sword blade,
intense blue energy glow running along the edge, arcing lightning crackling across the steel, fine sparks flying off into the air,
visible forge texture and micro scratches on the blade surface,
a chinese man mid sword-swing, roaring, handsome asian features, half of the face falling outside the focal plane,
wearing tang dynasty clothing, sleeves and collar whipping with the motion,
heavy snowfall driven sideways, individual flakes streaking, motion blur on the swing arc,
thin smoke curling around the blade only, kept sparse so it never covers the metal,
dark cold background, strong rim light, high contrast, shine effect, many fine details, dramatic composition
给烟单独写一句「只绕着刀身、保持稀薄」，这一条一加，画面立刻从糊变清楚。
