“血的訓訓”是使用 FontVibe AI 创作的血滴字体文字效果。粗体深红字母，表面湿润暗红，长长的血滴末端凝成圆珠，在侧光下孤立于纯黑背景。

竖版惊悚小说封面，3:4。纯黑、无纹理背景，画面边缘完全压暗；中央是唯一焦点，巨大的两行中文主标题，准确清晰地写为「嗜杀」，第一行「嗜」、第二行「杀」，占画面高度约55%，字间紧凑，居中对齐。标题为定制粗壮中文血滴展示字：宽厚笔画、紧凑字腔、边缘略不规则；每个笔画的下缘覆盖真实高黏度深猩红血液。血液从笔画底部重力下坠，根部宽厚，向下收窄成连接液丝，最低端形成饱满泪滴；液丝有可见表面张力和弯月形液面，底部凝成近黑红的小血泊。颜色由活动滴流的#CC0000过渡到积液的#3D0000，凸起液滴出现小面积锐利湿亮反光，凝块区域为暗哑粗糙表面；字面有零星擦拭状鲜血接触污痕。右侧一束低位冷暗红侧逆光擦过滴液边缘，形成细窄高光；血液内部出现微弱深红透光，阴影为黑褐色。不得使用橙色、暖色背景、彩色装饰、卡通插画、喷漆感或水状细滴。 主标题上方居中，小型窄体无衬线白灰文字，准确写为「暗夜档案 01」；主标题下方留出黑色呼吸空间，居中一行小号白灰文字，准确写为「惊悚短篇集」；底部居中是作者名「沈烬」，字距加宽，冷灰色。所有辅助文字干净平整、无血迹，与主标题形成清楚层级。摄影级实拍特效质感，微距液体细节，锐利焦点，深黑留白，高对比封面排版，文字必须准确无误. Portrait horror novel cover, pure black untextured background with the outer frame falling into absolute black. The only focal element is the exact Chinese title 「血的訓訓」, split across two tightly grouped lines: 「血的」 and 「訓訓」, dominating roughly 55% of the image height. Render the title as dense, heavy custom display lettering with broad solid strokes, compact internal counters, and slightly irregular cut edges. Every lower stroke edge is coated in physically convincing high-viscosity deep crimson blood: broad pooled roots taper into attached connective filaments, ending in swollen rounded teardrops. Show surface tension, curved liquid menisci, and small near-black red pools beneath the longest drops. Fresh flowing blood transitions from #CC0000 to accumulated #3D0000; raised droplets carry tiny sharp wet specular highlights, while clotted sections are dark, matte, and granular. Add sparse wiped blood contact smears across the title faces. A low cold dim-red side rim light grazes the liquid edges, producing narrow highlights and weak internal deep-red translucency; shadows remain black-brown. No orange, warm backdrop, colored decoration, cartoon illustration, spray-paint texture, or watery thin drips. Above the title, include the exact small clean cool-gray text 「暗夜档案 01」. Beneath the title, preserve a field of black negative space with the exact small cool-gray text 「惊悚短篇集」. Include the exact author name 「沈烬」 in spaced cool-gray characters near the lower cover area. All secondary text is flat, clean, and free of blood, with clear hierarchy against the blood title. Photographic practical-effects finish, macro liquid detail, razor-sharp focal plane, deep black negative space, high-contrast book-cover typography, all rendered text accurate and legible.
