Lin Yuan transmigrates into a parallel world suffering from a cultural disconnect, where he becomes a player representing the Dragon Kingdom in a four-star dungeon. At the start of the game, players must purchase three gifts for their elders from a marketplace within a limited time. Players from other countries are eliminated after choosing weapons or items with inauspicious meanings. Drawing on the knowledge he gained in his previous life, Lin Yuan successfully clears the challenge and activates his own system.
