Liu Ming accidentally picked up a mysterious wooden box. It seemed ordinary, but it hid a mystery - as long as ordinary objects were put into it, rare treasures would come out. Once, he put a portion of Liangpi into a box, and what he took out was a brilliant golden hairpin. What's even more shocking is Jin Chai's owner, Su Waner. She comes from distant ancient times and is burdened with unknown missions and secrets. A box connects two worlds, an object affects thousands of years, and a legend spanning time and space begins.
