Since Zheng Liang was occupied with meetings with the ministers regarding important matters, he sent a message to Yang Ning that he wouldn't be able to join her for lunch, and she doesn't need to wait for him. Understanding his responsibilities, Yang Ning completed her work and had lunch before tagging along with Xiaowei to the training grounds.
In the morning, while Xiaowei was braiding Yang Ning's hair, Yang Ning found out that yesterday, Zheng Liang had ordered Gu Lan to teach Xiaowei self-defense. She even went to the training grounds and attempted to do archery with the guidance of Gu Lan.
No wonder she suddenly disappeared after getting out of the carriage.
