Legend of Fu Yao Episode 5

During the second round of the Hunting and Fighting Game, no one wants to pair up with Fu Yao, so Wu Ji assists her. However, their umbrella breaks, and they fall. The stick from uncle Zhou opens a hidden cavern where the unconscious Fu Yao learns a fighting technique. Though Zong Yue heals her physical injuries, she suffers from partial memory loss and continues to practice the sword fighting techniques unconsciously in her sleep, making her tired all day.
