Retired cultural relic restorer Shen Deshan binds to the All-Things Valuation System. Dragged by his niece and nephew to clear out the old house, he buys a house full of junk for eighty-eight thousand, being mocked as senile by the second-hand dealer Ma Sancai. Unexpectedly, from old account books, remnant chapters, exchange drafts, and rusted keys, he unearths three hundred and sixty million in old banking firm assets, subsequently cracking the salt merchants' secret treasury, recovering overseas national treasures, and excavating a multi-billion ancient kiln site, all the way slapping greedy villains in the face.
