At the end of the Shang Dynasty, King Zhou's tyranny made life unbearable for the people. Li Jing, one of the dynasty's most renowned generals, and his wife Yin Shiniang, faced a strange event when their child was born as a ball of flesh. Believing it to be a demon, Li Jing split it open, revealing a two-year-old boy named Nezha. To protect her child, Shiniang sent Nezha to the Nuwa Temple to be raised. Nezha befriended Yang Jian and Lei Zhenzi, and the trio delved into the world of kung fu. Yang Jian's sister, Yang Lian Hua, fell in love with Nezha at first sight. Meanwhile, King Zhou's indulgence in beauty and favouritism towards Su Daji led to widespread destruction. Jiang Ziya then led Nezha, Lei Zhenzi, and Yang Jian to persuade King Wen and assist King Wu in leading an army against Zhou. Together, they fought against the injustice.
