Bai Yu has been able to see things that others cannot see since she was a child. She was born with yin and yang eyes and a very yin body, making her the best candidate for cultivation.
Bai Yu always knew that his life did not belong to him. He died when he was born, and his parents were reluctant to let him go. They even changed his fate and gave him a marriage.
Other people in underworld marriages are all lonely ghosts, fierce ghosts, evil ghosts, and ghost kings. However, these are extremely weak, and they are not as good as his man at all. Even the king of hell will respectfully call him "sir" when he sees him. His origin is a mystery, and he doesn't know what he is.
On the day he turned eighteen, a man who claimed to be his husband came to his door. In the eyes of others, the man who made all ghosts cry was actually a dog-skin plaster, extremely sticky. She accidentally discovered that whenever she was in danger, she would be saved by a tiger cat, and the tiger cat turned out to be a man. As a way of repaying her kindness, she reluctantly took the man in as a savior, not as a man.
