Taoist Priest, Are You a Weasel?

On the day I was born, 99 snakes were sacrificed at the door of my house. Three days after I was born, my grandfather performed the ceremony for three days. My identity is not simple, I am the reincarnation of a thousand-year-old immortal. I accepted an old man as my godfather. Eight years later, Lao Huangpizi asked me to dig up a piece of jade on my grandfather's grave. If I broke it, I could regret the engagement with the snake that had become a fairy. … It succeeded, and not long after... A girl of the same age as me came to my house, her name is Lu Qixue. She is very beautiful... But my godfather said that she is my daughter. From then on, the cause and effect between me and the snake fairy began—— Where will the original engagement go after it is shattered?
