The world has three realms: heaven, hell, and human world. The heaven and hell realms are collectively called the Dharma Realm and are ruled by the Princess of the World (Princess of the Heaven Realm). From the Second Heavenly Hell War more than 1,000 years ago to the present, everything has been relatively peaceful. But since then, Hai Yiqi, the princess singer of the heaven world, disappeared from the world, and Hai Lanxiao, the princess singer of the prison world, was seriously injured and was taken to the forbidden area by the military commander Teng Cuo of the prison world. In the heavenly world, Dongfang Huaizhu and his party began to search for the princess, but unexpectedly found a girl they thought had fallen from the sky - a girl who only knew her name was Luo Zakixia. She was 80% similar to the singer Hai Yiqi, and this name was also the former pseudonym of the singer Hai Yiqi. This girl seems to be the only clue. . .
