After a gestation period of three and a half years, Lady Yin, the wife of General Li Jing, gives birth to a flesh ball, which becomes a lotus flower, from which Nezha is born.

The people beg for rain, but the East Sea Dragon King Ao Guang ignores them, telling the yaksha Ye Sha to go and find children for him to eat.
