Li Sisi, slapped by the Empress, completely broke down. She responded to any question Liu Gongyun was asking and even outright admitted that she went to the Imperial Garden to stalk Prince Wei Ya.
Li Ren glared at her fiercely, but his daughter was completely ignorant of it.
Li Sisi came to the realization, that trying to hide and dodge questions would arouse more suspicion. So, she admitted everything freely.
However, she could never explain why a piece of her clothing was missing.
Her father is the Minister of War, and she had a slight trail in Martial Arts from her childhood. The maid who followed her was also skilled in martial arts, even a bit higher than Su Luo. On the pair of shoes in the maid's bundle, they found a dried reed.
Such reeds were only found beside Cuiwei Lake.
