In the southern part of the wilderness, or even further south, have you ever seen green-feathered ducks with oily green feathers?
Especially in the past two years."
"..." No.4 was stunned on the spot. He never expected such a question.
He indeed traveled to many places, but who would pay attention to such a thing?
He sat there in deep thought, reminiscing for a long time before he spoke, somewhat uncertainly.
"Now that you mention it, I think I have indeed seen something like that.
But it wasn't in the southern part of the wilderness, it was in Kuihou Country.
Last year, when passing by a lake, I saw some birds covered in oily green feathers, looking like ducks."
"Around which month?"
"April, I think."
"Oh, thank you. When the next batch of sweet rain is available for sale, I'll save a few drops for you first."
"Thank you very much." No.4 quickly clasped his hands in gratitude.
