In order to seek the elixir to save her adoptive father, she entered the immortal gate with mixed spiritual roots, but was treated with cold eyes.
But accidentally discovered the shocking secret of the sect's number one genius——
He is a righteous genius and a relic of the demon world!
He was sinister, cruel and ruthless, but he only focused on her.
Just because of her physique, she can purify his bone-corroding demonic energy.
This is a transaction of mutual use.
However, while spending time together day and night, he had feelings that he shouldn't have.
From "just using" to "I'll give you my life",
From "everyone gets what he needs" to "everything in the world is devoted to protecting you".
When his identity is exposed, the two factions pursue him.
She fled with him, and he became a demon for her.
"Everyone in the world can abandon me, but not you."
