Guided by the star map left behind by the Star Speaker Alpha, the Thousand Sunny sailed smoothly through the Chaos ocean. This path, marked by ancient forces, emitted a unique frequency, and the surrounding turbulent currents of order obediently bypassed it, while the wandering Chaos creations ignored it.
"The rules governing this path are at a very high level," Allen sensed the surrounding energy flow, "As if I've been granted some kind of passage privilege."
Robin sorted through the ancient inscriptions recorded in the temple. " The Star Speaker's message mentioned that this path leads to the Hall of Echo' —a place that records all the secrets of the Cradle of Chaos."
The voyage was not without its challenges. Although most dangers were avoided, the route itself tested the voyager's wisdom. Sometimes it required solving puzzles made of pure concepts, and sometimes finding the right exit from Labyrinth of Rules.
"Turn 30 degrees to the left, and then... wait, this spatial coordinate is self-correcting!" Nami stared intently at the instrument, beads of sweat forming on her forehead. The Log Pose, though no longer spinning wildly, was beating in a more complex pattern.
Franky manipulated General Franky's arm, constructing a temporary rule stabilizer around the ship. "Super-Concept Engine at full power! These rule changes are more difficult to handle than the weather in the New World!"
Luffy, however, was thoroughly enjoying himself, watching the ever-changing, strange scenery outside the window. "Wow! That cloud that just passed by seemed to be singing!"
"That's not a cloud," Allen said solemnly, "That's the embodiment of the sound of rules. If we accidentally intrude, our consciousness might be assimilated into an eternal melody."
Upon hearing this, Usopp quickly withdrew his hand from the porthole. "It's better to get through this dangerous place quickly!"
After several hours of arduous travel, the scenery ahead began to change dramatically. The Chaos mist gradually thinned, replaced by a strange space composed of pure rules. Countless luminous conceptual threads intertwined in the air, forming intricate and beautiful patterns. At the center of this space, a magnificent palace constructed of memory crystals floated.
" The Hall of Echo..." Robin gazed at the building, which radiated a soft light, her eyes filled with longing. "It is said that all knowledge since the birth of the universe is recorded here."
Just as the Thousand Sunny was about to approach, the entire space suddenly trembled violently. Conceptual threads danced wildly, and memory crystals emitted a blinding light.
"What happened?" Shen Jinbe the boat and cautiously observed his surroundings.
Allen's expression changed. "Someone is forcibly extracting the core's fundamental rules! This will disrupt the balance of the entire Cradle of Chaos!"
A massive surge of uncontrolled, rule-based energy erupted from the Hall of Echo, colliding and annihilating each other, creating a chain reaction. Space began to collapse, and conceptual threads snapped, transforming into dangerous fragments that flew in all directions.
"This process must be stopped!" Luffy stretched out his arm and grabbed a piece of rule flying towards the ship. His rubber palm was instantly contaminated by concepts and began to become transparent.
"Don't make direct contact!" Allen hurriedly deployed his Definition Domain to help Luffy dispel the pollution. "These shattered concepts will rewrite the very nature of those who come into contact with them!"
Chopper immediately checked Luffy: "Thank goodness we arrived in time! Any later and the captain's hand might have become transparent forever!"
The collapse intensified, and cracks began to appear on the outer walls of the Hall of Echo. Through the cracks, one could see a massive, swirling vortex of energy within the hall, spinning uncontrollably and frantically drawing energy from its surroundings.
"That's the core of the rules of the cradle!" Allen sensed the energy flow in that vortex. "If it's not controlled, the entire Cradle of Chaos will collapse!"
"What should I do?" Zoro gripped the hilt of his sword, ready to slice through the flying, dangerous shards at any moment.
Allen quickly analyzed the situation. "Someone needs to enter the Hall of Echo to stabilize the core of the rules from within. But this is extremely dangerous; the out-of-control flow of rules will constantly assault the consciousness of anyone who enters."
"I'll go!" Luffy said without hesitation.
"I'll go too." Allen nodded. "My Power of Definition should be able to help. The rest of you, please provide external support and try to slow down the collapse."
Just as the two were about to act, an ancient and weary voice suddenly echoed from the Hall of Echo:
"Finally... the successor has arrived..."
Accompanied by this voice, a figure composed of pure rules slowly rose from the hall. He possessed an ancient aura similar to that of the Star Speaker Alpha, but it was far more profound and powerful.
"I am Omega, the Keeper of Secrets," the figure's voice resounded directly in everyone's consciousness, "Guardian of the rules, watchman of knowledge."
His gaze fell on Allen: "Young successor, you have passed the Star Speaker's test. Now, it's time to face the real trial."
Omega spread its arms, and the entire space governed by the rules responded. The collapse temporarily ceased, but an even more dangerous storm of rules was brewing.
"If you want to save this impending destruction, prove to me with your power—prove that you are worthy to inherit this secret that concerns the survival of the universe."
The storm of rules began to swirl, forming a massive conceptual vortex behind Omega. Countless fragments of knowledge danced within it, each containing the power to change the world, and each carrying the danger to destroy the mind.
"Be careful," Allen Luffy, "This opponent is more dangerous than the Star Speaker. He controls the most fundamental rules of the Cradle of Chaos."
Luffy grinned, his rubber arm inflating. "Let him see our determination to keep going!"
Battle is imminent.
