Deep in the quiet old streets of the bustling city, there is a "Wanling Grocery Store". The boss Lu Chen is lazy and mysterious, specializing in collecting old things that have been forgotten by time; the new employee Su Jiu is beautiful and confused, and always feels that the boss is unfathomable. When a destined person pushes in the door with old things, Lu Chen can tear apart time and space by touching the old things and send them back to the past to resolve their obsessions. The rusty pocket watch hides twenty-two years of regrets, the broken erhu sobs the love and hate of the Republic of China, and the half-cut pencil is engraved with the redemption of a young man... Behind each old thing is a life that has been dusted. But what Su Jiu doesn't know is that her amnesia-free life experience, her boss's true identity, and the bond between the two that has spanned hundreds of millions of years are slowly being revealed along with the cause and effect line of old things - she is not an ordinary employee, he is the Lord of All Spirits; she is not a mortal, he is the person she has never forgotten despite her nine reincarnations.
