The day of Ne Zha's birthday finally arrived, and the Li residence in Chentangguan was bustling with activity. Li Jing and Lady Yin had prepared a grand banquet to celebrate their son's special day. The courtyard was decorated with colorful lanterns and streamers, and the air was filled with the delicious aroma of food.

Taiyi, as Ne Zha's master, was in charge of the preparations. He had invited all the important figures in Chentangguan, hoping that this birthday banquet would be a chance for Ne Zha to gain the respect and acceptance of the townspeople.

Ne Zha was in high spirits. He had been looking forward to this day for a long time, not only because it was his birthday, but also because he could finally show off his skills in front of everyone. He put on his new clothes and practiced his martial arts moves in his room, imagining the amazed looks on people's faces when they saw his abilities.

When the guests started to arrive, Ne Zha greeted them with a big smile. But he noticed that many of them still looked at him with fear and suspicion. Ignoring their reactions, he led them to the banquet hall, excited to start the celebration.

Just as the banquet was about to begin, a figure suddenly appeared in the courtyard. It was Shen Gongbao, with a malicious smile on his face. "Happy birthday, Ne Zha," he said sarcastically.

Ne Zha was surprised to see him. "What are you doing here? You're not welcome," he said, frowning.

Shen Gongbao ignored Ne Zha's words and walked towards the crowd. "Ladies and gentlemen, do you know what kind of child Ne Zha really is?" he asked, his voice echoing through the courtyard.

Everyone looked at each other in confusion. Li Jing stepped forward and said, "Shen Gongbao, what do you mean by that? This is a happy occasion. Don't cause any trouble."

Shen Gongbao laughed coldly. "Happy occasion? You're all being deceived. Ne Zha is not the reincarnation of the Spiritual Pearl as you thought. He is the Demon Pill!" he shouted, pointing at Ne Zha.

The crowd gasped in shock. Ne Zha was stunned. He looked at his parents, then at Taiyi, hoping they would deny it. But the expressions on their faces told him that what Shen Gongbao said was true.

At that moment, Ao Bing arrived. He saw the chaos in the courtyard and immediately understood that something was wrong. He walked towards Ne Zha, trying to comfort him. "Ne Zha, don't believe him. It doesn't matter what you are," he said.

But Ne Zha was too angry and hurt to listen. He turned to Taiyi. "Is it true? Am I really the Demon Pill?" he asked, his voice trembling.

Taiyi sighed. "I'm sorry, Ne Zha. There was a mistake. But you're still you. You can still be a hero," he tried to explain.

Ne Zha couldn't accept it. He felt betrayed. Just then, he noticed that Ao Bing was wearing the same kind of clothes as the sea monsters they fought before. A thought flashed through his mind. "Are you... one of them?" he asked, his eyes filled with anger.

Before Ao Bing could answer, Shen Gongbao whispered something in his ear. Ao Bing's face changed. He remembered his mission from the Dragon Clan - to use the power of the Spiritual Pearl to flood Chentangguan and prove the Dragon Clan's loyalty to the heavens.

With a heavy heart, Ao Bing summoned his ice - magic powers. The temperature in the courtyard dropped rapidly, and ice began to spread everywhere. "I'm sorry, Ne Zha. But I have to do this," he said.

Ne Zha was furious. "You traitor! You're no friend of mine!" he shouted, and launched an attack at Ao Bing.

The two of them, who were once friends, now engaged in a fierce battle. Their magic powers clashed in the air, creating a powerful shockwave that shattered the lanterns and tables in the courtyard. The guests panicked and fled in all directions.

Li Jing and Lady Yin tried to stop them, but they were no match for the power of the two boys. "Stop! Both of you, stop!" Lady Yin cried, but her voice was drowned out by the sound of the battle.

As the battle raged on, Ne Zha and Ao Bing's powers became more and more powerful. The ice and fire collided, and the entire Chentangguan was on the verge of being destroyed. And so, the birthday banquet that was supposed to be a celebration turned into a chaotic and tragic battle, with the fate of Chentangguan hanging in the balance.
