Su Wan, 25 years old, works part-time in a museum. Her biggest worry is the unpaid mortgage.
Until she was on the night shift, a jade turtle from five thousand years ago told her: "You are a descendant of the Red Mountain Witch, and your fiancé is the ancient mythical beast Gouchen. He will be here soon."
Su Wan dialed 110 expressionlessly: "Hey, are you a demon spirit? A national first-class cultural relic has become a spirit."
Then he came - silver hair and golden eyes, with the power to cut through mountains and rivers, but he was trapped in a drum washing machine for half an hour.
He said that he would fulfill the engagement made five thousand years ago.
Su Wan said, "Okay. Write my name in the wedding room, pay the mortgage, and sign the contract."
She thought it was just a deal where everyone gets what he wants.
Until she discovers that at the end of five thousand years of waiting, what awaits her is not only a marriage contract, but also an impending crisis...
Purpose: People who save the world can also just want to pay off their mortgage. Ordinary days are also worth protecting.
