Metropolis: I Handed over He's Bi to the Country

Lin Fan traveled through time and obtained a great treasure appraiser. At the beginning of the game, he was at his ancestral antique stall, and found out that he had been missing for nearly two thousand years and made a national jade seal made of He's jade. It was priceless! Master Chen: "I'll pay you one billion, and I'll take this piece of jade seal passed down from the country!" Lin Fan: "Little old man, you want to take one billion? Are you looking down on my national jade seal?" … Just when everyone thought Lin Fan was going to get rich, Lin Fan actually handed over the Imperial Seal to the country! I got five hundred yuan, plus a banner! Netizen: Is this person stupid? This is a national treasure worth more than one billion, and he exchanged it for 500 yuan and a banner? That's ridiculous! System: "Hey, congratulations to the host, for completing the task of handing in the national jade seal, and rewarding the host 15 billion RMB!" Lin Fan: "Everyone laughs at me for being crazy, but I laugh at others because they can't see through it." This novel and its characters are purely fictitious.
