A sudden turmoil arises in the worlds of Yin and Yang, and two young men join hands to embark on the road to slaying ghosts and becoming gods. They broke through treacherous and confusing situations, defeated monsters and monsters, and tempered their bonds in life and death tests. But fate has revealed the cruelest truth - one person's soul has returned to heaven and earth, while the other person is guarding the world alone, leaving only an unfinished song of mourning.
Purpose: To explore the bonds and sacrifices involved in life and death decisions, to show the courage of young people to stick to justice in the dark, and the growth of reconciliation with pain after losing a loved one.
