Just then, a black-and-red light suddenly bloomed.
"The passage to Hueco Mundo has been established. Everyone, retreat immediately!"
Ulquiorra's calm voice rang out, snapping everyone out of their shock over Qin Yi's Zanpakutō.
"Quick! Quick! Quick! Everyone, move to Hueco Mundo immediately!" Urahara Kisuke shouted as if waking from a dream.
Only then did the crowd react. Figures immediately began rushing toward the newly opened passage.
"Trying to run?"
A cold light flashed in King Chengdui's eyes as anger exploded within him. He finally realized that these people had come here primarily to rescue Soul Society.
As for him? He had merely been an obstacle along the way.
What enraged him even more was the fact that he had actually fallen into a disadvantage during this battle.
Damn it! Absolutely infuriating!
"AAAAAH!"
Throwing back his head, King Chengdui let out furious roars. His aura erupted once more, and his body began evolving again, advancing toward an even higher level of power.
"Kill every invader!"
"Don't let a single one escape!"
Suddenly, a chorus of voices rose from Soul Society's entrance as large groups of Shinigami poured in. At that moment, an immense pressure surged across the battlefield, causing the Soul Society Shinigami's expressions to change dramatically.
"That's...?!"
"The Shinigami Legion of the Nie Kingdom!"
"Gasp! There are even more of them than before!"
"My God! How are we supposed to stop this?!"
As everyone looked over, all they could see was an endless sea of black figures. Like a massive flood, they surged forward. The thunderous noise shook the earth and nearly deafened everyone present.
There were simply too many. Far too many.
Ten thousand? A hundred thousand? No. The numbers had already reached the level of millions, perhaps even tens of millions.
At the front stood a man with purple hair and violet eyes. His expression was indifferent, his entire body radiating cold ruthlessness.
"My King, Zilin has arrived to report in. It seems I haven't come too late."
He slowly raised the purple Zanpakutō in his hand and pointed it toward the sky.
"Kill."
In an instant, the black ocean roared. The massive army surged forward like a tidal wave.
Within that sea of Shinigami stood a black-haired man wearing glasses. Aizen looked toward the battlefield ahead, where one King stood in the sky while another stood upon the earth. A strange light flickered behind his lenses.
"Those people from the other world truly are terrifying. They're absurdly strong."
Although his words sounded like praise, the corners of his mouth slowly curved upward.
"But that's what makes it fun."
Under Zilin's relentless slaughter, the Hōgyoku had absorbed an enormous quantity of soul energy. It had expanded to a level even Aizen could never have imagined. Based on his calculations, that power might already be enough to destroy the entire world.
Meanwhile, Urahara Kisuke and the others' expressions changed drastically.
"Retreat! Hurry and retreat!!"
The incoming army resembled a plague of locusts. Setting aside their individual strength, their sheer numbers alone were enough to make one's scalp go numb and extinguish any thought of resistance.
One figure after another rushed into the dimensional passage at even greater speed before disappearing. Faced with the massive reinforcements from the Nie Kingdom, the Soul Society Shinigami could no longer summon even the slightest desire to fight. This wasn't a battle between equals, it wasn't even close.
In the sky, Qin Yi's eyes narrowed as he looked down at King Chengdui. Then, he spoke coldly.
"It seems today is not the day we settle this fight to the death."
His figure flashed. In an instant, he tore through the void and prepared to withdraw.
"Then we'll decide the winner on another battlefield!" King Chengdui panted heavily as he roared toward the sky. "Trying to escape?!"
He bent his knees, preparing to give chase. But at that moment...
Crack!
The mask on his face shattered. His body immediately staggered.
"Damn it!"
After fighting for so long, his power had finally begun to decline. Li Yuanli's attacks combined with Qin Yi's assaults had inflicted severe damage on King Chengdui's body, causing his energy to drain at an alarming rate. At this moment, he had already reached his limit.
His eyes locked onto Qin Yi, filled with hatred. This battle had brought him no advantage whatsoever.
As the vast army of the Nie Kingdom flooded in, both the Soul Society forces and Qin's Nation rapidly withdrew. Remaining behind at the very end were the Arrancar Espada and the various generals of Qin's Nation.
"Hundred-Step Flying Sword, Immortal!"
The first to act was a man dressed like a wandering swordsman. The longsword at his waist remained sheathed, but as soon as he softly uttered those words...
Bzzzz!
A powerful sword cry rang out. In an instant, he became a streak of light. His figure turned into an afterimage, trailing arcs of lightning as he charged into the ranks of the Nie Kingdom Shinigami a hundred meters ahead.
Swish! Swish! Swish!
Cold sword light filled the sky. His figure split into thousands upon thousands of images.
Pfft! Pfft! Pfft!
When the sword light finally faded, he was somehow already back where he had started. He slowly raised his head, revealing a grim skeletal mask.
Crack.
The mask shattered. Beneath it was the face of a mature and composed middle-aged man.
Ge Nie, the Sword Saint from The Legend of Qin.
Without even glancing back, he turned and walked away. After a few steps, he entered the dimensional passage and disappeared.
"Southwest sector... annihilated."
Only then did the enemy vanguard in that direction begin collapsing. Thousands of Shinigami fell like harvested wheat, forcing the Nie Kingdom troops to retreat repeatedly.
The commanders guarding the various sectors all inflicted tremendous damage upon the enemy before withdrawing. Of course, compared to the Nie Kingdom's military force numbering in the hundreds of millions, such losses were less than a drop in the ocean. But they did succeed in slowing the advance for a brief moment.
And that brief pause was enough. The Soul Society Shinigami and everyone from Qin's Nation in Hueco Mundo completely vanished.
"Looks like our enemies are quite formidable as well." Aizen walked over to King Chengdui and let out a soft sigh. He looked as calm as ever.
"Aizen."
King Chengdui had already returned to his original appearance. His face was somewhat pale, and his body seemed unsteady. The excessive energy expenditure had left him in poor condition.
"Next time we go to war, you'll handle one of those two."
Aizen blinked in surprise. He hadn't expected King Chengdui to say something like that.
"Captain Chengdui, with my current strength, I'm afraid..."
Before he could finish, King Chengdui let out a cold laugh.
"I trust your abilities. The benefits you've gained while fishing in troubled waters are worth far more than a single battle, aren't they, Aizen?"
The emphasis he placed on those last two words made Aizen's heart tremble slightly. Then, he smiled.
"In that case, since we're allies, it's only proper that I lend a hand. I'll take care of King Yuanli."
King Chengdui merely snorted and turned away. Zilin followed silently behind him.
"Summon all the experts within the kingdom. Bring them into this world. Every Venerable must be present. And..."
At this point, an unusually solemn expression appeared on King Chengdui's face. For the first time, he even seemed hesitant. His voice paused briefly before continuing.
"Bring over the one I obtained from that Unknown Hero World as well."
Zilin froze. A rare look of seriousness appeared on his face.
"Your Majesty, are you certain? That person's power far exceeds ours. If his seal is broken, it could bring catastrophe."
The corner of King Chengdui's mouth twitched. This time, however, all hesitation disappeared from his eyes.
"I never make the same decision twice. Bring him."
Meanwhile, within Las Noches, Qin Yi's expression was equally grave.
"Notify Madara Uchiha, Hashirama Senju, Whitebeard, and Sengoku. Have them enter this world immediately. From this moment on, we must be prepared for battle at any time."
The true storm was about to arrive.
