Huaisu, the dragon son of the East China Sea, was deceived by a witch during his spiritual practice. His godfather Wang demoted him to the mortal world. He took over a pawnshop in Yinxi City and named it "Jubaodang". He raised potted flowers as an assistant, caught a fox to do odd jobs, and lived a leisurely life from then on.
Only regular customers of the pawn shop know that the transactions here are not limited to bartering for money. You can also exchange your own treasures for any treasure in the world. Moreover, the shopkeeper guarantees his personality and will never do anything illegal. Of course, the treasures traded by both parties must be of equal value.
However, the new shopkeeper Huai who took over Jubaodang is a bit "picky": if a customer trades mundane treasures, he will look down upon him and send the guest away immediately.
And some secrets slowly surfaced with the exchange of treasures...
