The story is based on the traditional Chinese folklore about a boy named Chenxiang. His mother, Sanshengmu, was a goddess and his father, Liu Yanchang, was a mortal. Since their marriage was forbidden, his maternal uncle, Erlang Shen, who was a god, punishes them by killing Liu Yanchang. Sanshengmu escapes and gives birth, but Chenxiang grows up without knowledge of his ancestry. Sanshengmu possesses a magical Lotus Lantern whose light can scare away evil. When Erlang Shen, a strict and powerful god, kidnaps Chenxiang, Sanshengmu fights to save him. Unfortunately, Erlang Shen is victorious and Chenxiang is forced to live in his palace on the sacred mountains. Erlang Shen then imprisons Sanshengmu beneath a mountain for her crimes. Although he is quite young, Chenxiang manages to escape from the palace, taking the magical lotus lantern that Sanshengmu lost during the battle. After surviving adventures with many beloved characters of Chinese mythology, Chenxiang finally matures into a courageous boy who must battle Erlang Shen to win Sanshengmu’s freedom and fall in love at the same time.
