Hidden Pollinator

The grocery store in Changxingji sends a bundle of "bean feed" or "forage" to Jiyulou's stable every day. I wonder what secrets are hidden in it?

Sent to Changxing Collection,

Turn left after the house ahead on the left and go straight.

Until there is no house left,

1. Enter the last right courtyard door,

Conversation with Chu Xuan in the stables of Jiyu Tower;

Pick up in the bean trough next to it,

Get the prop Rose Letterhead;

Presented to Chu Xuan Rose Letterhead,

The conversation is over and the mission is complete.
