Apocalyptic Grocery Store

He ran a grocery store, but when it was about to go bankrupt, he accidentally obtained the apocalyptic grocery store system. The grocery store was therefore upgraded into an apocalyptic grocery store that could travel through the apocalypse! In the last days, money is like waste paper, treasures are like garbage, and a piece of bread is worth thousands of gold. When people in the last days see him, they feel like they are seeing God! "Mr. Richest Man, the 100 boxes of Kang Shuaifu instant noodles you ordered have arrived. The total price is one billion US dollars. Thank you!" "Your Majesty, the steak you requested has arrived. It's still hot. Please use it slowly. Also, please give me your crown. Thank you!" "Mr. President, are you sure you want to trade such high-tech scientific research results for a hamburger?" "Beautiful lady, it doesn't matter if you don't have treasures or money, you can use your beauty to exchange for everything you want!" In short, this is a seller who takes cheap items in exchange for everything from the end of the world to become the supreme being. This novel and its characters are purely fictitious.
