She is the Immortal of the Nine Heavens, who guards the ruthless road and cuts off love and hate in this world.
He is her only disciple. He has been born from the dust and has only been for one person in his life.
She said: "Only by being ruthless can you live forever."
He smiled: "If I live forever without you, it would be better to become a demon and fight against heaven."
Later, she died in love, and he guarded her remaining soul and waited for thousands of years.
Intention: Being ruthless is not the way, only moving one's heart can lead to longevity.
