We all know the key phrase "hunting deer" with Yuiman, and now I shall explain Yachie's.
So there's this Chinese traditional medicine ingredient that's believed to be solidified jidiao semen. You may find this shit in marshy areas where there's a lot of deer – because jidiao are sexually aroused by deer and they would ejaculate into the water. Those emissions eventually solidify and catch on some driftwood by the water. So yeah, jidiao are turned on by deer, and Yachie's deer horns might just raise the topic of jidiao reproduction in general – or whether Yachie donates such ingredients, for science.
It's actually dried sponge, by the way.
