An auction? That could be interesting. Di Tou remembered back when he was on Earth, in many of the novels he read the protagonist would go to an auction where a battle of wits and reputation would take place, and through their creativity, and surprisingly large amount of money, they would be able to take home the best treasure of the night. Although, of course, this best treasure might not be the final item that everyone thought was the real treasure, but rather a piece of scrap or unidentified good that everyone else was thought overpriced.
Thinking of hidden treasures, Di Tou couldn't help but be tempted.
