Ten years ago, the Xie family was found guilty of rebellion and the entire family was executed. Eight-year-old Xie Buchen escaped by chance and became a beggar. When he was about to die on a snowy night, he was rescued by the seventh princess Shen Yueling who came out of the palace to worship the Buddha. She put a cloak on him, left some bread, and whispered, "You have to live."
Ten years later, when Shen Yueling was in her hairpin years, the government was in turmoil and the country was about to be destroyed. She was accused of marrying the prince of an enemy country, and her fate of marrying far away was imminent. No one knows that behind the current princess, there is always an invisible guardian - the feared ghost king Gu Ying, who has controlled all ghosts.
He lurked in the darkness, just to step out of the netherworld when she really needed him, and declare to heaven and earth: no one can force her to marry someone she doesn't want to marry; and the king of hell can't accept anyone she wants to protect.
