The sky above Chentangguan was a maelstrom of energy as Ne Zha and Ao Bing, their souls ablaze with new - found power, faced off against Wuliang Xianweng and the Four Dragon Kings. The once - peaceful town was now a battlefield, with the remnants of buildings and the cries of the townspeople serving as a backdrop to the epic showdown.

Wuliang Xianweng, his face contorted with anger and frustration, glared at Ne Zha and Ao Bing. "You think you can defeat me? You're nothing but arrogant children," he hissed, his voice filled with venom.

Ne Zha stepped forward, his eyes blazing with determination. "Your reign of terror ends here, Wuliang Xianweng. We won't let you get away with your evil deeds any longer," he shouted, his voice echoing through the devastated town.

With that, Ne Zha and Ao Bing launched their most powerful attacks yet. The combination of Ne Zha's fiery Demon Pill and Ao Bing's icy Spiritual Pearl created a force that seemed to shake the very foundations of the earth. The attack hit Wuliang Xianweng and the Dragon Kings, sending them reeling backwards.

But the enemy was not easily defeated. Wuliang Xianweng quickly regained his composure and launched a counter - attack. He summoned a dark cloud of energy, filled with lightning bolts and powerful winds. The cloud surged towards Ne Zha and Ao Bing, threatening to engulf them.

Ne Zha and Ao Bing, undaunted, used their combined powers to create a shield. The shield of fire and ice held firm against the dark cloud, but the pressure was intense. Ne Zha and Ao Bing could feel their strength waning, but they refused to give up.

Just when it seemed like the battle would reach a stalemate, Shen Gongbao, who had been waiting for the right moment, made his move. He had been secretly gathering his own spiritual power, and now he unleashed it in a powerful blast. The blast hit the Dragon Kings from behind, catching them off - guard.

"Take this, you villains!" Shen Gongbao shouted, his voice filled with a mix of anger and satisfaction.

The Dragon Kings, already weakened by the attacks from Ne Zha and Ao Bing, were now in a desperate situation. They tried to fight back, but their powers were no match for the combined forces of Ne Zha, Ao Bing, and Shen Gongbao.

Ao Guang, the Dragon King of the East Sea, looked around in despair. He realized that his actions, driven by anger and revenge, had led him down a dark path. He saw the destruction of Chentangguan and the suffering of the people, and a sense of guilt washed over him.

"What have I done?" he murmured, his voice filled with regret.

Ne Zha and Ao Bing, noticing the change in Ao Guang's demeanor, decided to give him a chance. "Ao Guang, it's not too late. You can still make things right," Ne Zha said, his voice firm but also filled with a glimmer of hope.

Ao Guang looked at Ne Zha and Ao Bing, and then at the devastated town. He took a deep breath and made a decision. "You're right. I've been blinded by my anger. I'll help you stop Wuliang Xianweng," he said, his voice filled with determination.

With the unexpected help of Ao Guang, the balance of the battle shifted even further in favor of Ne Zha and Ao Bing. They launched a final, all - out attack on Wuliang Xianweng. The combined powers of Ne Zha, Ao Bing, Shen Gongbao, and Ao Guang were too much for Wuliang Xianweng to handle.

In a final, desperate attempt to escape, Wuliang Xianweng tried to use the large cauldron he had brought to Chentangguan to absorb their powers. But Ne Zha and Ao Bing were ready. They used their combined powers to break the cauldron, shattering it into pieces.

With the cauldron destroyed, Wuliang Xianweng's powers were greatly weakened. Ne Zha and Ao Bing, seizing the opportunity, launched a final, decisive attack. The attack hit Wuliang Xianweng square in the chest, sending him flying backwards. He crashed to the ground, defeated.

The battle was over. Ne Zha and Ao Bing had emerged victorious. The townspeople, who had been hiding in fear, slowly emerged from their shelters. They looked at Ne Zha and Ao Bing with awe and gratitude.

"Ne Zha! Ao Bing! You saved us!" the townspeople shouted, their voices filled with joy.

Ne Zha and Ao Bing looked at each other, a tired but satisfied smile on their faces. They had not only saved Chentangguan but also exposed Wuliang Xianweng's dark secrets. And in the process, they had grown stronger, both as individuals and as friends.

As the sun began to set over Chentangguan, casting a warm glow over the town, Ne Zha and Ao Bing knew that their journey was far from over. But they were ready to face whatever challenges lay ahead, together.
