Yu Gui took the quest item to find the NPC, Zhao Si. Zhao Si was relatively easy to find. You just need to wander around the village entrance. If players encountered him and tried to get a quest from him, he would curse you, "You want to die, huh! Disturbing Lao Tzu's rest!" No matter what you asked, there was only this one answer. Therefore, players treated him as a normal NPC.
Yu Gui walked up to him with a handful of crow feathers and asked respectfully, "Sir, I have some crow feathers here. Do you want them?"
Zhao Si's eyes lit up. "Show me."
