She is the God of Heaven who is in charge of three thousand worlds. Once she was assassinated and her godhood was shattered, she was forced to bind an infinite fast travel mission to restore order in the collapsed world line.
He is a demon king who is feared by everyone in the world of cultivation. His cultivation is as high as the sky and he is murderous. However, he has been waiting for a prophecy for three thousand years.
When they met for the first time, she pointed a broken sword at his throat and planted a heart-locking curse on his heart: "I control your life and death."
Instead of being angry, he smiled: "From today on, you belong to me."
"You're mine too," she said. "One for one, fair trade."
The Demon Lord, who no one dared to get close to for three thousand years, has since become a clingy and jealous large dog - if she looks at others one more time, he will kill him; if she says one more word, he will eat her; when she sleeps, he can watch her by the bed all night long.
She thought it was just a deal where everyone gets what he wants.
But he said: "I have been waiting for you for three thousand years, do you think you can still leave?"
When the ancient demon god broke the seal, and when the hidden truths were revealed layer by layer, she discovered that the entanglement between them was far more than just one world.
