After receiving their missions, Taiyi and Shen Gongbao left the celestial realm. Taiyi, with the Spiritual Pearl carefully in his arms, made his way towards Chentangguan, where Li Jing and his wife were expecting a child. He was full of excitement and anticipation, looking forward to fulfilling his task and seeing the Spiritual Pearl being reincarnated into a heroic figure.

Meanwhile, Shen Gongbao, filled with resentment and jealousy, hatched a devious plan. He knew that the Spiritual Pearl held great power and prestige, and he couldn't bear the thought of Taiyi being the one to guide it. So, he decided to intercept Taiyi on his way to Chentangguan.

On a stormy night, as Taiyi was flying through the clouds, Shen Gongbao suddenly appeared in front of him. "Taiyi, stop right there!" Shen Gongbao shouted, his voice filled with anger.

Taiyi was startled but quickly regained his composure. "Shen Gongbao, what are you doing here? Don't you have your own mission to attend to?" he asked.

Shen Gongbao sneered. "Your mission should have been mine! I'm just as capable as you are. Hand over the Spiritual Pearl!" he demanded.

Taiyi hugged the Spiritual Pearl tightly. "No way! Master assigned this task to me. You can't just take it away," he retorted firmly.

With that, the two disciples engaged in a fierce battle. Magic spells flew through the air, and the dark clouds above them swirled even more violently. Shen Gongbao, using his sly and tricky fighting style, managed to gain the upper hand for a moment. He launched a powerful attack that sent Taiyi flying backwards.

Taking advantage of the situation, Shen Gongbao snatched the box containing the Spiritual Pearl. He quickly opened it and swapped the Spiritual Pearl with the Demon Pill that he had hidden. Then, he threw the box back to Taiyi, who was still trying to regain his balance.

"Taiyi, you're too naive. Now, you go and deliver the 'Spiritual Pearl' to Chentangguan. Let's see what kind of hero you'll create," Shen Gongbao laughed wickedly and disappeared into the night.

Taiyi, not realizing the swap, continued his journey to Chentangguan. When he arrived at Li Jing's residence, he was greeted by the excited couple. "Master Taiyi, you've finally arrived! We've been waiting for you," Li Jing said with a big smile.

Taiyi, still a bit flustered from the battle, quickly composed himself. "Yes, yes. Let's get started. The Spiritual Pearl is ready to be reincarnated into your child," he said.

Following the ancient ritual, Taiyi used his magic to release the energy of the "Spiritual Pearl" (which was actually the Demon Pill) into the womb of Li Jing's wife. As the energy entered her body, a strange and powerful force filled the room. The air became thick with a dark, oppressive aura, and the candles flickered wildly.

Li Jing and his wife looked at each other, a hint of worry in their eyes. "Master Taiyi, is everything okay? Why does it feel so strange?" Li Jing asked nervously.

Taiyi, also feeling a bit uneasy, tried to reassure them. "Don't worry. It's just a powerful energy. The child will surely be a great hero," he said, though he secretly wondered why the energy felt so different from what he had expected.

Nine months later, Li Jing's wife went into labor. The entire Chentangguan was filled with excitement and anticipation. But as the child was about to be born, a series of strange and terrifying events took place. Dark clouds gathered rapidly above the city, and bolts of lightning flashed across the sky. The ground trembled, and a deafening roar echoed through the air.

Finally, with a loud cry, the child was born. But instead of a normal baby, what emerged was a powerful and mischievous creature. The baby, who was Ne Zha, immediately broke free from the midwife's arms and started flying around the room, causing chaos. His eyes glowed with a fierce red light, and his small body was surrounded by a dark, swirling energy.

Li Jing and his wife were shocked and horrified. "What is this? Is this our child?" Li Jing exclaimed in disbelief.

Taiyi, realizing that something had gone terribly wrong, quickly tried to contain Ne Zha. "Stay still, little one! There's something wrong here," he shouted, using his magic to create a barrier around Ne Zha.

But Ne Zha was too powerful. He broke through the barrier with ease and continued his rampage. He even managed to snatch Taiyi's bag of magic treasures and started playing with them, causing all sorts of magical effects to go off randomly.

Just then, a voice came from outside. "What's going on in there? Is everything okay?" It was the local magistrate, who had been alerted by the commotion.

Li Jing, with a heavy heart, opened the door. "I'm sorry, everyone. It seems our child is... different," he said, his voice filled with sadness and disappointment.

The news of Ne Zha's strange birth spread quickly throughout Chentangguan. The townspeople were filled with fear and suspicion. They started to believe that Ne Zha was a monster, a bringer of bad luck and disaster. And so, from the very moment he was born, Ne Zha was met with fear and rejection from the world around him.
