He is the supreme emperor of the three realms. He is supposed to protect all living beings, but he abandoned his priesthood for his beloved wife and violated the laws of heaven.
She died by repairing the sky with her body, but he went against the will of heaven and protected her remaining soul in the palm of his hand, raising it for a full ten thousand years, and then sent her to be reborn in the Queen of Heaven's belly. But when she opened her eyes, she didn't remember anything. She turned around and married a mortal in the world.
In anger, he killed the mortal by mistake, knowing that he could not escape the catastrophe, so he used his cultivation to create an illusion of life after life, trapping the two of them together. He wanted her to taste the coldness of the world so that she would give up and come back to him.
There was also a demon king who could have broken through the illusion and taken her away, but he was willing to stay with her trapped in the dream of the illusion, watching her fall in love with others and forget herself life after life.
In the last few reincarnations, the emperor was the first to be unable to hold on.
It took him ten thousand years to make atonement for his obsession; and the journey she had to complete was to see clearly how deep and painful this love was, but she was still willing to hand over her whole self.
If you ask for something but don't get it, you must force it. The level of love traps people, demons, and gods.
Intention: True love is not about possessing and forcing, but about learning to let go, and it is self-sacrifice for perfection and protection.
