Three times married to Yama

When I was twenty, my dad forced me into a marriage that everyone feared.
The wedding date is set for July 15th, the Ghost Festival, and the man I'm marrying...
It's not a person either.
Because I was born without a heartbeat, my father used a secret technique to keep me alive. The only way to survive is to marry this mysterious husband.
On the night of the wedding, amidst a flurry of paper money, a strange paper figure descended from the sky carrying an eight-bearer phoenix palanquin.
I took the place of the girl from my village and became his wife.
After my marriage, my father mysteriously disappeared, leaving behind a book called "The Record of a Hundred Ghosts in the World." From then on, I stepped into a fantastical and bizarre world with this book in hand.
The thousand-year-old Corpse King is my bodyguard, the ten-thousand-year-old spirit creature is my magic weapon, with the Spirit-Crossing Fan in hand I can get rid of all the world's obsessions, and the power of spiritual healing can cure the mountain spirits and monsters of the three realms. I have become the world's only Spirit-Crossing Master.
My mysterious husband said that marrying me was not his wish, and that once the agreed time was up, he would give me my freedom and grant me a long life.
I accepted it readily; it's just a divorce, I can remarry.
but……
I've been married three times already, and the groom is still him?
