Ziliujin? Well, these are quite amazing and I would love to meet this Gu Zi XI if he knows more about them.

[He definitely has to meet them. Such amazing tools! He felt inspired. Could he figure out something like this? Suddenly his few accomplishments felt like nothing. He needed to be more imaginative! Especially in a world without spirits, what did collecting spirits and finding spirits matter?]

Chroma is very hard to use in such a way I find. But is demichroma also not a good fit as a substitute?
