Modify All Things: I Become a God in the Auction House

[System + auction house + management + group portraits + cultivating immortals + there is a price] After being assigned by his family, Xiao Yue only took over a run-down auction house. An old servant, a counting house, a waiter, and a warehouse full of junk products that no one wants. Until the Vientiane revision system awakens. Broken swords can be turned into spiritual weapons. Waste elixirs can be changed into precious elixirs. Fragments can be changed into secret techniques. Even an auction house that is about to close down can slowly be transformed into the most dangerous place in the world of immortality. The down-and-out appraiser and the frustrated auctioneer also walked into the Treasure Pavilion one by one. But when each item fetched sky-high prices, changes followed. Black film, secret realm, sect, city lord's mansion... --- The system can modify everything. Only the price cannot be changed.
