For a moment Jiang Cheng isn't really capable of answering the first question; the idea of Wei Wuxian leaving to find his path - no. He left because he wanted to protect the Wen Sect and he... He had never been able to accept that, the broken promise hanging between them.

It's much easier for him to focus on their chores rather than think about stupid Wei Wuxian and their stupid arguments. He feels stupid for even thinking about it.

"Then it has to dry." Jiang Cheng nods. "I have no questions. Thank you." Tense and terse, but trying.
