Su Wanying, a skilled antique restorer, lives an ordinary life. During an extremely luxurious glass night banquet, she accidentally broke an inconspicuous ancient jade, and the gears of fate were deflected. That man, Ye Junlin, the powerful "Night Emperor" in the imperial capital, came to her world like a god, and with a contract she couldn't refuse, he forcibly dragged her into a bizarre modern world of immortality.
He is cold and domineering and regards her as the key to unlocking the secrets of ancient jade, but every time she is on the verge of despair, he turns into the strongest barrier.
From a rookie who was forced to embark on the path of spiritual practice, to a proud woman who stirred up the storm, Su Wanying not only awakened the sleeping bloodline through the tempering of ice and fire, but also cracked open the frozen heart of the emperor bit by bit. When the ancient conspiracy and fateful entanglements surface, is their relationship a continuation of the transaction or the origin of a long-destined love? Can the weak firefly illuminate the eternal loneliness and warm the glass-like heart?
