The "tribute" mentioned by the Wind Lightning Swordsman was not simply for gaining favour with the NPCs, it was a repeatable task.
According to the information provided by March, the Duke of Lu Ding loved to collect some novel treasures. Many items acquired from quests or slaying monsters, which players weren't sure about their specific use, could be exchanged for silver taels.
Of course, the worth of the items needed to be assessed beforehand.
The NPC in charge of assessing could be found in every major pub in the capital city. Players could exchange their bizarre trinkets for cash on the spot, once it had passed preliminary assessment. Only items of considerable value would get a recommendation letter to transact directly with the legendary Duke of Lu Ding.
Ye Weiming shook his head lightly, "I'm actually here for a task."
