I'm looking for this novel which I can only remember one part. He joins a sect and there he harasses this girl (I think she's using fire to make pills). Basically I think the sect revolve around making pills and this girl is quite a high rank there. She has a bad temper and mc keeps hitting on her. On the chapter when he meets her she gets annoyed by him and wants to mess with him.
Reminds me of Spirit Realm on wuxiaworld except it’s artificing (artifact/weapon refinement) instead of pills
