Su Wantang, a young spiritual master from the lower world, broke into the ancient spiritual tomb by mistake and accidentally made a contract with the ancient spiritual king who had been sleeping for thousands of years (actually the reincarnation of the tomb keeper Gu Zhaozhi), and has been haunted by Gu Zhaozhi ever since. As the guardian of the spiritual tomb, Gu Zhaozhi appears to be cold and taciturn, but in fact he is waiting for the reincarnation of his former lover Su Wantang, guarding him for thousands of years just to reunite. After the two reunited, Gu Zhaozhi loved Su Wantang extremely, helping her defeat the villains who looked down on her, and accompanying her through the disputes in the three realms. Su Wantang relied on his ability to control spirits and his tough character, and grew from a transparent person in the lower world to a spirit control master recognized by the three realms. The plot is centered on "sweet pet daily + face-slapping counterattack". Through the male protagonist's protection, the female protagonist's counterattack, and the love between the two spanning thousands of years, it shows the fusion of strong points (slapping the villain in the face, reversing the situation) and sweet pets (extreme preference, daily sprinkles of sweets). In the end, the two resolve their ancient grievances and live happily. !
