During the Republic of China, Su Wanning and Gu Yeshen were newly married, but they were assassinated by Aunt Liu in collusion with evil cultivators. Their souls were separated from their bodies, and their unborn child could not be saved. Her soul was rescued by Chacha, the princess of the underworld, and stayed at the Wangchuan Ferry at the junction of humans and ghosts, while Gu Yeshen waited day and night in the world. When his soul was wandering, he and his wife experienced the catastrophe of separation between yin and yang.
From the ghosts breaking the wall in the strange illusion, to the conspiracy of Pluto's nemesis Lord Xuansha, from the thunder trial in the underworld, to the breaking of evil spells in the world of the world, a rescue across Yin and Yang begins. In order to repay his life-saving grace, Chacha urged Pluto to take action; Taoist Master Yunqing walked along the sky, secretly spreading vitality; Gu Yeshen relied on his affectionate obsession to break through the formation and wait for his soul to return.
The seven-day period is imminent, and the insidiousness of the Soul Locking Array, the calculations of the Yang world, and the fetters of the underworld are intertwined. When the last ray of morning light pierced the haze, Su Wanning's soul finally broke through the obstacles and reunited with Gu Yeshen in the world.
After a near-death experience, the evildoer subdues the law and the resentment disappears. Three years later, the new child "Nian'an" arrived as promised, confirming the fate of "what is lost will eventually come back". Looking at each other on the banks of the Forgotten River, the mediation in the depths of the netherworld, and the mutual presence of fireworks in the world, all turn into the quiet perfection of the years. This is a life-and-death love that spans Yin and Yang, and it is also a fantasy story of the Republic of China about protection, redemption and fateful reunion.
