As Yiyi was the best one at following without being discovered, Liu Xinyu just went along with her instead of showing her own smartness in such a situation. On the way, there were plenty of times, when Liu Xinyu wanted to rush up to commit a murder but she had to stop in time.
These bastards threw all kinds of insults around and didn't hesitate to hit when they got annoyed too.
It was a good thing that rain became their perfect cover and as slowly the night fell, it became even harder to find Liu Xinyu's presence but it also made it difficult for Liu Xinyu to walk in this mountain forest. Those traffickers had flashlights but she didn't and even if she did, she wouldn't be able to use it under this situation.
