Su Wanying's life was completely overturned by a worn-out jade pendant inherited from her ancestors in the summer of her twenty-fourth year. Under the neon lights of the bustling city, there is a family of practitioners that has lasted for thousands of years and an earth-shattering undercurrent of spiritual power hidden. She, a tiny "firefly", was forced to be involved in the center of the storm of light.
Fu Yeshen is a business emperor who stands at the top of money and power. His true identity is the ruler of the dark night world who is cold and powerful and treats all living beings as pawns. He came to find a treasure that had been lost for hundreds of years, but he didn't expect that the clue to this treasure actually tied to an ordinary urban girl.
A contract that cannot be refused binds people from two worlds together. He thought she was an ant that could be manipulated at will, but he saw in her a spark that could start a prairie fire. She thought he was a ruthless devil, but in the depths of his frozen eyes, she glimpsed a period of lonely waiting that spanned eternity.
When the ancient destiny awakens and Liuli City turns into a battlefield, she is no longer the Su Wanying who is at the mercy of others, but a descendant of the god who controls the light of fireflies. And he, the emperor of eternal night, is he willing to let go of his desire to control everything and become her only guardian? This is not only a competition of strength, but also an affectionate game that spans time and space.
