The cover features an ominous and towering gothic-style structure, the 魂殿, with sharp, spired rooftops glowing faintly with blood-red runes etched across their dark stone surfaces. Suspended in front of the structure is a fragmented "反派系统界面," a collection of floating digital panels, glowing in cool blue tones with data streams pulsating around it. Mechanical chains extend outward from the system interface, tangling with the edges of the architecture as if binding it. A swirling, vivid fire effect in the lower foreground represents the "异火融合态," with dancing flames of white-blue (骨灵冷火) and dark violet-black (虚无吞炎). In the upper background, a smoldering void reveals shattered heavenly skies, highlighting massive spatial rifts with floating remnants of celestial star maps.

The book title, 加入魂殿后，我靠反派系统横扫, appears in bold, sharp-edged Chinese characters, using a customized gothic-inspired font with slight technological inflections. The main text is primarily glowing a fiery crimson with subtle black shadows for depth. The author name, 本人最爱可乐, is positioned smaller beneath the title in a sleek, modern sans-serif font for contrast, glowing faintly in blue and white to harmonize with the system interface.

The title is prominently placed across the center of the cover, slightly overlapping the 魂殿. The system interface dominates the mid-to-upper portion, framed by the mechanical chains. The异火特效 swirls prominently in the lower foreground, adding intensity to the mood, while the 破碎的诸天裂隙 provide an expansive, mysterious backdrop. The author name is placed subtly at the bottom of the cover, ensuring balance without overpowering the visuals.
