The scene he's filming with Gao Wu is, interestingly, a sharp contrast with the one he just did with Xin Hulei.
Unlike his shixiong, Gao Wu's character, Rong Zi, is an even-tempered young man, with very insightful opinions about Frozen Peak cultivation techniques, and who always volunteers to help Yan Shuyi with his work copying some of the sect library's older manuscripts.
He's also rarely punished, and despite being a demon has no problems adapting to sword immortal cultivation techniques, despite the pain it causes his body to go against his demonic core's nature.
Yao Shen can't help thinking that many of the novel's tragedies would have been avoided if Yan Shuyi just fell in love with Rong Zi instead of Xie Huan.
But then he guesses he wouldn't have a drama to film.
Who wants to watch something about two well-matched people falling in love, experiencing no hardship, and living happily ever after?
