MC Shop from Another World

Villager Li traveled to the world of MC a long time ago and became a glorious "profiteer" villager, with the mission of defrauding players of their emeralds. Later, he traveled to a magical continent - Bafang Continent, and there was a redemption bar where he could load modules and redeem items from each module! So... Villager Li: This is really a good place to make money! Knights or swordsmen or assassins: the villagers are great! Please lower the price of your weapons! Mages or alchemists or formation mages: The villagers are great! Please lower the price of your materials! (PS: Easy store opening flow)
