I've seen this concept in a few English original xianxia/xuanhuan novels where the MC's "cheat" is a shop by which he/she can sell things to for points to buy cultivation stuff with. However, I can't recall reading / seeing description of any translated novels with this premise. Anyone come across one before?
I think I know what you're talking about. Does the mc find a gold sculpture that he uses to strengthen his body?
Not looking for a specific novel, I haven't read any with a shop system. If you have something in mind, I would love to hear it! I meant a story where the MC has an ability that can "sell" them cultivation resources or a manual. But the MC has to earn points with the shop by giving stuff to it.
