Although Su Liang was quickly defeated by Ning Jing and had to change to another wooden stake, they did not stop.
Sparring on top of the Plum Blossom Pile requires extreme concentration.
When they were practising martial arts before, they were wielding weapons, so there were fewer leg techniques. The Plum Blossom Pile was specially created by Ning Jing for Su Liang to make up for her weaknesses.
It wasn't until dusk that the two left the Training Ground. Su Liang analyzed her shortcomings, while Ning Jing listened but said nothing.
Deep into the night, there was still no news from anyone regarding Su Liang.
She knew that Ning Jing was right after all.
The letter she sent to Duanmu Che might not even be read, or even if he did, he might not believe it.
Since she had to ask for help, she couldn't just sneak into the prince's mansion without notice and perform martial arts in front of Duanmu Che to prove that she was not weak.
