The Su family ancestral hall was filled with incense, and Su's father kowtowed to his ancestors: "Today, my daughter Su Nianxing entered into a ghost marriage with Master Pluto!" A necklace with a jade pendant was handed to Su Nianxing's hand. It was an amulet given by his father and a token of the ghost marriage. When she revealed her identity as a supernatural detective and was involved in a campus mystery case, the pressure of the underworld suddenly descended. Pluto's stern voice shocked everyone: "Have you ever asked me if you want to touch my underworld wife?" But before the storm was over, the rich second-class marriage that the grandfather of Su's parents had planned for her in the early years was suddenly revealed. Pluto was furious and forced her to tear up the engagement letter! He even swore an oath in front of the memorial tablets of the ancestors of the Su family: "I, Lu Zhiming, will protect the Nianxing in full forever!" Unexpectedly, as soon as the oath fell, Pluto became so angry that he vomited blood and died, and was urgently taken back to the underworld by Yin Shi. From then on, no one dared to underestimate this new student in the folklore department - her husband was the Lord of the Underworld who could be so angry with her that his soul was damaged. When she met the vampire young master Musian, he tricked her into taking pills and getting married in the back mountain park. After Su Nianxing turned black, she became Su Nian'er, a descendant of Nuwa in 500 years ago. She couldn't control her red snake tail and was driven away by the people with stones. She hid in the cave and waited for his return.
