Chapter 391: Appearance of the Shadow Demon

###

The stained glass of the library dome suddenly oozed black brain fluid, and the Shadow Demon's snarling laugh quantum‑entangled among the bookshelves. Ao Li's Inverse Scale reacted explosively, the blade edge slashing toward the source of the sound, but what fell was the very Gui Xu Chronicle — the pages disintegrated in midair into three hundred screaming infant heads, each pupil reflecting the mirrored play of the twin children.

"Cognitive Projection!" Zixiao True Person's sword technique just began, and Taiyi Pure Light was swallowed by the shadow of the bookshelf. Qinglin's God‑slaying crossbow automatically locked onto a point in the void, but the bolt transformed at the moment of release into an umbilical cord, winding backward to entangle his mechanical prosthetic eye. "Visual trap! They're hidden in..."

####【Conceptual Parasitism】

Before the words finished, seven Shadow Demons were birthed from the shadows of the crowd. These monsters, gestated by cognitive shadows, were not solid; their bodies coursed with a hybrid spectrum of Taiyi Pure Light and Nirvana Fire, and their talons were entwined with memory fragments from Lín Jìn's Star Sand Crystallization. The chest of the first Shadow Demon suddenly split open, revealing a phantom of a black‑haired infant sucking the chaotic spirit marrow.

"Dragon Flame Impact!" Ao Li's roar carried a Dragon Clan incantation, but the blaze rebounded from the Shadow Demon's surface. The bookshelf licked by fire suddenly feathered into a living scroll, and ancient forbidden curses crawled toward everyone like maggots. Gongxu Yue's mechanism box ejected the Mohist forbidden device "Heavenly Craft Furnace," and what spewed from the furnace was not molten lava but the creation amniotic fluid of a silver‑haired infant.

####【Dimensional Collapse】

Lín Jìn's Star Sand right hand suddenly quantum‑shifted, piercing through the Shadow Demon's phantom straight into the spacetime fold behind the bookshelf. When Nirvana Fire detonated in the Fourth Dimension, the entire library collapsed into a Möbius Strip structure — the floor beneath them became the ceiling, and the text on the pages flowed backward into primordial mycelium. Three Shadow Demons seized the chance to merge, forming a shadowy giant blade shaped like an Abyss Return Ruler that slashed toward Ao Li.

"Clang!"

At the instant the Boundary‑cutting Blade collided with the Shadow Blade, the chaotic spirit marrow that erupted was not sparks but three hundred altered memories. Ao Li saw herself in a parallel dimension voluntarily leaping into a jade basin, using Inverse Scale to carve new toys for the twin children. This cognitive shock created fissures in her defense, and the Shadow Blade naturally sliced open her left shoulder, splashing Golden Blood onto the ancient tome and burning out the missing final chapter of the Shadow Demon Codex.

####【Fetal Treasury Formation】

Qinglin's God‑slaying crossbow core suddenly overloaded, and the radiation wave drew a Ghost Void forbidden formation in the void. At the moment the formation solidified, all Shadow Demons abruptly knelt, their spines detaching and assembling in the air into a complete Ghost Void Fetal Treasury Scripture. Each character of the sutra birthed miniature Shadow Demons, and these newborn larvae burrowed into the bookshelf, transmuting the classic into a pulsating cognitive Zigong.

"Destroy the Array Eye!" Zixiao True Person bit his tongue, and his life‑essence blood painted a dual‑yin reverse formation on the Taiyi sword. The sword light touched the sutra, and the entire library suddenly contracted, with the walls exuding amniotic fluid mixed with page fragments. In the viscous torrent, everyone saw the truth of the Polaris Tower — its foundation was built from three hundred Crystallized villages, and each villager's celestial spirit canopy extended a Shadow Demon umbilical cord.

####【Cognitive Burn Scar】

Gongxu Yue's mechanical arm was inserted into the Heavenly Craft Furnace, and the furnace spewed a cleanser laced with temporal whale brain fluid. When the liquid touched the Shadow Demons, the monsters suddenly emitted infant cries, and after the black‑mist bodies faded, the villagers' Quantum Afterimages were revealed. Lín Jìn's Star Sand right hand seized the chance to pierce the Array Eye, and Nirvana Fire burned along the umbilical cord toward the jade basin projection in the void.

"No!" The silver‑haired infant's phantom leapt out of the basin, and the creation pure light froze the flame. The black‑haired infant seized the moment to thrust the Shadow Demon Codex into Ao Li's wound, where the pages rooted and sprouted within her flesh. When the first new leaf of a forbidden chant pierced the skin, the entire library suddenly healed itself, erasing all battle traces as if the recent clash had been a collective hallucination.

####【Silent Finale】

The group gasped, leaning among the intact bookshelves, and only the scar on Ao Li's shoulder testified to what had occurred. Qinglin's God‑slaying crossbow core bore an additional Ghost Void inscription, and Gongxu Yue's Heavenly Craft Furnace inhaled and exhaled a rhythm resembling a fetal heartbeat. When Zixiao True Person opened the Shadow Demon Codex, blood‑red annotations surfaced on the yellowed flyleaf:

**The cognitive war has no victor**

**Your scars are the altar**

**Gui Xu eternally births new life**

Outside the tower, a snow‑plain wolf's howl suddenly echoed, and under the moonlight the Polaris Tower cast two entwined shadows — silver‑haired and black‑haired — carving a new jade basin with Ao Li's Boundary‑cutting Blade.
