[X] ...Wait
I actually believe this is the most interesting option for Ling Qi to choose here. It would be the most frustrating choice for Ling Qi, as stated by this option's description, since simply waiting is something Ling Qi has rarely done. It provides an opportunity for character growth as she would have chosen this option in spite of her own desires, presumably with the bigger picture in mind. This is especially compelling when juxtaposed with the influence the Forest King arc continues to have on Ling Qi, as shown in the prior update. Unlike the Forest King arc, in which Ling Qi gave in to her innermost desires, she would be resisting them here.
I also agree with Abeo in that deciding to wait here does not contradict SCS's insight either.
There is no peace in emptiness, no content in stillness. Stagnation is death; act, change, move, think, and grow until the very end.
"..Wait" provides an opportunity for Ling Qi to think and may provide an impetus for her to change and grow, even if it's only in minor ways. With this option, she is not ignoring her problems but facing them in novel ways.
Looking at the other options:
[] Help the other village
This is the most boring option for me. Ling Qi has no personal connection to this village and I'm concerned about the content of this option overlapping with this update. I'm not sure how interesting this option would be character-wise. Strategically, "...Wait" may be just as good if not better as well.
[] Return
This option fits with Ling Qi's feelings toward Zhengui and Xiulan. This involves Ling Qi giving in to her own desires, prioritizing them over her own mission. It's an interesting path for Ling Qi to go down on, and would probably be my second choice. With that being said, it's not a positive path of development for her.
[] Hunt them down
Ling Qi gives in to her own desires in this option as well. In this case, however, those desires are entirely selfish. From a character perspective, this is an inferior version of Return in my opinion. I'd rather Ling Qi give in to her worries about Zhengui and Xiulan than to her desire to continue the chase.
There are strategic reasons Ling Qi would consider for choosing each of these options, but she would be influenced by her emotions regardless of the option we choose, so it's important to take them into account.
Edit: I'm now convinced there's enough justification behind Return even without involving Zhengui or Xiulan for it to be considered.
