Chapter 12: The Black Book Unlocks — Battle Through the Heavens
The aftermath of the Freshman Examination left Ayush in a state of heightened vigilance. The bond with Wang Dong was deepening, and so was the danger. Each genuine smile, each moment of trust, felt like another thread weaving him tighter into the script he was meant to break. He needed an edge—something beyond the resources of Douluo, beyond even the stolen legacies of the Dragon God.
That night, after Wang Dong had fallen asleep, Ayush retreated deep into his spiritual sea. The Black Book floated serenely above his Sea of Consciousness, its dark cover still and silent. But tonight, something was different.
As Ayush focused on it, a soft, unfamiliar hum resonated through his soul. The Book's surface shimmered, not with the usual mission logs or inventory lists, but with a new, pulsating script:
BLACK BOOK CORE STATUS UPDATE…
MULTIVERSAL ANCHOR SCAN COMPLETE.
WORLD NEXUS DETECTED: [DOULUO CONTINENT — PRIMARY TIMELINE].
ENERGY SIGNATURE SYNCHRONIZATION: 41.7%.
SECONDARY REALM RESONANCE DETECTED…
UNLOCKING: REALM #1 — BATTLE THROUGH THE HEAVENS.
Ayush's breath hitched. Battle Through the Heavens — that was a story from another world entirely. A world of Dou Qi, alchemy, and Heavenly Flames. What did it have to do with him? With Douluo?
The Book's cover slid open a fraction. Instead of pages, a swirling vortex of energy appeared—a gateway not of space, but of concept. From within, a stream of information flowed into Ayush's consciousness, not as words, but as laws, as principles, as energy patterns.
He saw:
· Dou Qi Cultivation Methods — pathways of energy circulation completely different from Spirit Power. More violent, more explosive, centered on the dantian rather than the spirit rings.
· Alchemy Formulations — recipes for pills that could cleanse meridians, boost cultivation, and even alter fate.
· Heavenly Flame Signatures — traces of twenty-three world-burning flames, each with its own nature and power.
· Battle Techniques — from the low-tier Furious Lion's Roar to the earth-shaking Angry Buddha Lotus Flame.
This wasn't just information. It was a system. A parallel cultivation path.
The Black Book's interface updated:
NEW FUNCTION UNLOCKED: REALM ASSIMILATION.
CURRENT REALM: BATTLE THROUGH THE HEAVENS (TIER 1 ACCESS).
AVAILABLE FOR INTEGRATION:
· DOU QI FOUNDATION METHOD (Compatible with Spirit Power. Can be cultivated simultaneously.)
· BASIC ALCHEMY KNOWLEDGE (Requires spiritual fire control. Current capability: Insufficient.)
· LOW-TIER BATTLE SKILLS (Can be adapted to Spirit Power usage.)
WARNING: Integration of foreign energy laws may cause planar instability. Use with caution.
Ayush's mind raced. This changed everything. He wasn't just a rebel with stolen Douluo treasures. He was now a multiversal cultivator.
He could feel the Book humming with potential. It wasn't just a library or a mission log—it was a bridge. A bridge between worlds, between systems of power. And it had chosen him.
He focused on the simplest integration: Dou Qi Foundation Method. The energy pathways mapped themselves into his mind. Unlike Spirit Power, which flowed through meridians and settled in the spirit core, Dou Qi gathered in the lower dantian, condensing into a cyclone of pure, explosive force.
Cautiously, Ayush began to circulate energy according to the Dou Qi method. Almost immediately, he felt a difference. The ambient spirit energy of Douluo, when filtered through this new pathway, transformed. It became sharper, hotter, more volatile. A faint, fiery warmth bloomed in his dantian—a Dou Qi seed.
At the same time, his Spirit Power remained undisturbed, flowing through his meridians as usual. Two systems. Two sources of power. One body.
The Black Book glowed softly.
INTEGRATION SUCCESSFUL.
DUAL-CULTIVATION MODE ACTIVATED.
SPIRIT POWER: LEVEL 18.
DOU QI: 1-STAR DOU DISCIPLE.
SYNERGY EFFECT: ENERGY CONVERSION EFFICIENCY +5%.
A smile touched Ayush's lips—cold, sharp, and full of possibility. This was the crack in the script Tang San could never have anticipated. A power from outside the system.
But with power came risk. He could not reveal this. Not to Wang Dong, not to Electrolux, not even to the Heavenly Dream Iceworm. This was his alone. A hidden blade.
He opened the Multiversal Chat Group. A new message waited.
Ancient_One_Theorist: Interesting. A dimensional frequency shift just registered in your sector. The Black Book is… flexing. Have you accessed a new realm, Nexus_Prime?
Ayush replied carefully.
Nexus_Prime: Realm #1 unlocked. Battle Through the Heavens. Testing integration now.
Star_Plucker_42: Ha! So it begins! That book's hunger is insatiable. It doesn't just record—it consumes worlds. Be careful, little node. The more you integrate, the more you become a bridge… and bridges can be crossed from both sides.
A chill ran down Ayush's spine. The Black Book was not just a tool. It was a living, hungry entity. And he was its gatekeeper.
He closed the chat and looked inward, at the fiery seed of Dou Qi glowing beside his serene Spirit Power core. Two energies, one soul. Two paths, one purpose.
Somewhere in the God Realm, Tang San stirred in his meditation. A ripple, faint and strange, had brushed against the edges of his divine sense. It felt like… a foreign flame. An unfamiliar energy signature. He frowned, his gaze turning toward the lower plane, toward Shrek Academy.
But by the time his divine sense swept over Ayush's dorm, the Dou Qi seed was hidden—masked by the Black Book' own shadow, tucked away in a fold of reality even a God King could not perceive.
Ayush lay back in bed, his eyes open in the dark.
The game had just expanded. The board was no longer just Douluo. It was multiversal.
And he was no longer just a reader, or a rebel.
He was a world-walker.
And his first step into the Battle Through the Heavens had just begun.
